An Object-Oriented Compiler Framework SableCC is an object-oriented framework that generates compilers (and interpreters) in the Java programming language. This framework is based on two fundamental design decisions. Firstly, the framework uses object-oriented techniques to automatically build a strictly typed abstract syntax tree that matches the grammar of the compiled language and simplifies debugging. Secondly, the framework generates tree-walker classes using an extended version of the visitor design pattern which enables the implementation of actions on the nodes of the abstract syntax tree using inheritance. These two design decisions lead to a tool that supports a shorter development cycle for constructing compilers. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

the plan9 text editor -- ed with a gui and multi-file editing sam -d can be used without X (with an ed-like interface -- but with more powerful regular expressions, the capacity to edit multiple files with a single command, and unlimited undo). Files can be added to an exiting sam session using the B command. sam without the -d option is an graphical editor with pop-up menus and a point+click interface. You'll want to read sam's manual page to use the full power of sam, but you can probably figure out how to do basic editing with a minimum of trial and error. If you have a Plan 9 terminal, you can use the Plan 9 terminal with sam to edit unix files, but not vice-versa; the Plan 9 authentication scheme does not honor remote execution requests from a non-Plan 9 system.

On Microsoft Windows 2000 (and Windows NT), all the user account information is stored within the SAM. It exists as a single file on the disk. The SAM is the primary target when hackers break into a system because it can be run through a password cracker. Key point: The SAM file is located in the path %systemroot%/system32/config/SAM However, a backup is also stored in the location %systemroot%/repair/sam._ as well as on any repair disk generated. (Note: if new repair disks haven't been created, then you'll likely only be able to see the Administrator's password there). Hackers usually go after the "repair" versions because they are not locked by the operating system. Tools: pwdump/pwdump2 Dumps the current password information using Windows registry calls. Must have administrative access for this to work. The data is written in a format for crack programs. samdump Reads the password information from the SAM file in a format suitable for inputting into crack programs. l0phtcrack The most popular utility for cracking Windows passwords. All these tools are available at http://www.l0pht.com/. History: The original version of WinNT allowed the password hashes to be easily retrieved, making cracking easy. In SP3, an optional utility called SYSKEY was added that encrypts the hashes. In order to decrypt them, the administrator needs to either type in the passphrase at boot time, store the passphrase on a floppy, or put the passphrase in the registry (dramatically reducing security, of course). Whatever way is used to boot the system, the keys are then stored in unencrypted format in memory, so administrative access can still read them (using the pwdump2 utility). SYSKEY is optional on WinNT, but is always running on Win2k. Key point: The PASSPROP and PASSFILT utilities can be used to enforce the choice of better passwords.

A free software implementation of the server message block (SMB) network file sharing protocol. Samba is usually implemented on networks that have a mixture of UNIX, Linux, and Windows computers and is designed for interoperable file sharing. From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A LanManager like file and printer server for Unix. The Samba software suite is a collection of programs that implements the SMB protocol for unix systems, allowing you to serve files and printers to Windows, NT, OS/2 and DOS clients. This protocol is sometimes also referred to as the LanManager or NetBIOS protocol. This package contains all the components necessary to turn your Debian GNU/Linux box into a powerful file and printer server. Currently, the Samba Debian packages consist of the following: samba - A LanManager like file and printer server for Unix. samba-common - Samba common files used by both the server and the client. smbclient - A LanManager like simple client for Unix. swat - Samba Web Administration Tool samba-doc - Samba documentation. smbfs - Mount and umount commands for the smbfs (kernels 2.0.x and above). libpam-smbpass - pluggable authentication module for SMB password database libsmbclient - Shared library that allows applications to talk to SMB servers libsmbclient-dev - libsmbclient shared libraries winbind: Service to resolve user and group information from Windows NT servers It is possible to install a subset of these packages depending on your particular needs. For example, to access other SMB servers you should only need the smbclient and samba-common packages. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A lot of emphasis has been placed on peaceful coexistence between UNIX and Windows. Unfortunately, the two systems come from very different cultures and they have difficulty getting along without mediation. ...and that, of course, is Samba's job. Samba <http://samba.org/> runs on UNIX platforms, but speaks to Windows clients like a native. It allows a UNIX system to move into a Windows ``Network Neighborhood'' without causing a stir. Windows users can happily access file and print services without knowing or caring that those services are being offered by a UNIX host. All of this is managed through a protocol suite which is currently known as the ``Common Internet File System,'' or CIFS <http://www.cifs.com>. This name was introduced by Microsoft, and provides some insight into their hopes for the future. At the heart of CIFS is the latest incarnation of the Server Message Block (SMB) protocol, which has a long and tedious history. Samba is an open source CIFS implementation, and is available for free from the http://samba.org/ mirror sites. Samba and Windows are not the only ones to provide CIFS networking. OS/2 supports SMB file and print sharing, and there are commercial CIFS products for Macintosh and other platforms (including several others for UNIX). Samba has been ported to a variety of non-UNIX operating systems, including VMS, AmigaOS, and NetWare. CIFS is also supported on dedicated file server platforms from a variety of vendors. In other words, this stuff is all over the place. From Rute-Users-Guide http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
a suite of programs which work together to allow clients to access to a server's filespace and printers via the SMB (Session Message Block) protocol. This means that you can redirect disks and printers to Unix disks and printers from Lan Manager clients, Windows for Workgroups 3.11 clients, Windows NT clients, Linux clients and OS/2 clients. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Samba adds Windows-networking support to UNIX. Whereas NFS is the most popular protocol for sharing files among UNIX machines, SMB is the most popular protocol for sharing files among Windows machines. The Samba package adds the ability for UNIX systems to interact with Windows systems. Key point: The Samba package comprises the following: smbd The Samba service allowing other machines (often Windows) to read files from a UNIX machine. nmbd Provides support for NetBIOS. Logically, the SMB protocol is layered on top of NetBIOS, which is in turn layered on top of TCP/IP. smbmount An extension to the mount program that allows a UNIX machine to connect to another machine implicitly. Files can be accessed as if they were located on the local machines. smbclient Allows files to be access through SMB in an explicity manner. This is a command-line tool much like the FTP tool that allows files to be copied. Unlike smbmount, files cannot be accessed as if they were local. smb.conf The configuration file for Samba. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Samba-client provides some SMB clients, which complement the built-in SMB filesystem in Linux. These allow the accessing of SMB shares, and printing to SMB printers. From Mandrake 9.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Samba-server provides a SMB server which can be used to provide network services to SMB (sometimes called "Lan Manager") clients. Samba uses NetBIOS over TCP/IP (NetBT) protocols and does NOT need NetBEUI (Microsoft Raw NetBIOS frame) protocol. Samba-2.2 features working NT Domain Control capability andincludes the SWAT (Samba Web Administration Tool) that allows samba's smb.conf file to be remotely managed using your favourite web browser. For the time being this is being enabled on TCP port 901 via xinetd. SWAT is now included init's own subpackage, samba-swat. Users are advised to use Samba-2.2 as a Windows NT4 Domain Controller only on networks that do NOT have a WindowsNT Domain Controller. This release does NOT as yet have Backup Domain control ability. Please refer to the WHATSNEW.txt document for fixup information. This binary release includes encrypted password support.

A "sandbox" is a mode of running a program that prevents it from having full access to the rest of the system. This is especially important for mobile code such as Java. A client can trust the code automatically downloaded from a web-site if the code runs in a sandbox and cannot harm the rest of the system. Key point: Sandboxes are being used more and more often for servers. This puts walls between different components that can help stop (or slow down) an intruder that has broken into one part of the system. The most important technique is to run services as a user account rather than an administrator/root account. For example, Microsoft's IIS creates a special user account (named "IUSR_XXXX" where XXXX is the system name) that the web-server runs under. When somebody breaks into the web-server, they still cannot gain control over the full system (unless they run some sort of local exploit in order to break out of this sandbox). Example: Example sandboxes are: user accounts As described above, running services under a user account prevents an intruder from gaining control over the entire machine. jail/chroot These utilities limit the view of the filesystem from a program. A program that runs under a chroot environment can only its own subdirectory, but no other parts of the filesystem. virtual machine The technique used by Java is to create an entirely separate "virtual" machine. A Java program has absolutely no access to the real machine except in a few places. A more extensive version of this is software like VMware or SoftPC that creates an entire virtual computer. Using VMware, you can boot a Linux or Windows virtual machine under the real machines. If an intruder compromises the virtual machine, he/she still cannot access the real machine.

The Anomy Mail Sanitizer - an email virus scanner The Anomy sanitizer is what most people would call "an email virus scanner". That description is not totally accurate, but it does cover one of the more important jobs that the sanitizer can do for you - it can scan email attachments for viruses. Other things it can do: Disable potentially dangerous HTML code, such as javascript, within incoming email. Protect you from email-based break-in attempts which exploit bugs in common email programs (Outlook, Eudora, Pine, ...). Block or "mangle" attachments based on their file names. This way if you don't *need* to receive e.g. visual basic scripts, then you don't have to worry about the security risk they imply (the ILOVEYOU virus was a visual basic program). This lets you protect yourself and your users from whole classes of attacks, without relying on complex, resource intensive and outdated virus scanning solutions.

Sash is a simple, standalone, statically linked shell which includes simplified versions of built-in commands like ls, dd and gzip. Sash is statically linked so that it can work without shared libraries, so it is particularly useful for recovering from certain types of system failures. Sash can also be used to safely upgrade to new versions of shared libraries. From Mandrake 9.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Stand-alone shell. sash serves as an interactive substitute for /bin/sh, for use when /bin/sh is unusable. It's statically linked, and inludes many standard utilities as builtins (type "help" at the prompt for a reference list). If you've installed sash before rendering your system unbootable, and you have some knowledge of how your system is supposed to work, you might be able to repair your system using init=/bin/sash at the boot prompt. Some people also prefer to have sash available as the shell for a root account (perhaps an under an alternate name such as sashroot) Configuration support is included for people who want this. Note: sash is not intended to serve as /bin/sh, and has few of the interactive features present in bash or ksh. It's designed to be simple and robust, for people who need to do emergency repair work on a system. Also note: sash doesn't include a built-in fsck -- fsck is too big and complicated. If you need fsck, you'll have to get at least one partition or disk working well enough to run fsck. More generally, sash is but one tool of many (backups, backup recovery tools, emergency boot disks or partitions, spare parts, testing of disaster plans, etc.) to help you recover a damaged system.

A vulnerability scanning tool designed to hunt for many ways into a system. Much hyped at the time; people feared that it would give a powerful tool into the hands of hackers everywhere. In practice, it was a dud: it was much to "noisy", was already outdated by the time it was released, was impossible to setup, and hasn't been really maintained. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Program designed to assess the security status of a computer or local area network (LAN) connected to the Internet. The program determines whether Internet-related software is misconfigured in a way that could render the system vulnerable to a cracker. The program is controversial because intruders as well as system administrators can use it to find loopholes. The controversy deepened when the program's authors, Dan Farmer and Wietse Venema, made the program publicly available through the Internet.

The University of Cincinnati's free VHDL 93 Analyzer This is the analyzer and intermediate representation for a free VHDL simulation system from the University of Cincinnati's Experimental Computation Laboratory. "scram", SAVANT's analyzer, converts VHDL into the AIRE intermediate standard form. AIRE is designed to be extensible by the user so that they can easily insert their own back ends. SAVANT includes a VHDLpublishing back end and a C++ publishing back end. The generated C++ can be compiled and linked against the TyVis library to allow end to end sequential or parallel simulation of VHDL. This version of the Debian package supports only sequential simulation - future releases should support parallel simulation as well.

n. [Unix] A terminal line which spews an infinite number of random characters at the operating system. This can happen if the terminal is either disconnected or connected to a powered-off terminal but still enabled for login; misconfiguration, misimplementation, or simple bad luck can start such a terminal screaming. A screaming tty or two can seriously degrade the performance of a vanilla Unix system; the arriving "characters" are treated as userid/password pairs and tested as such. The Unix password encryption algorithm is designed to be computationally intensive in order to foil brute-force crack attacks, so although none of the logins succeeds; the overhead of rejecting them all can be substantial.

An advanced ircII-based IRC client ScrollZ is advanced IRC client based on ircII code. It adds features normally found in ircII scripts like Toolz, PhoEniX, GargOyle or Lice. The main difference between these scripts and ScrollZ is the code. Where ircII scripts take a lot of disk and memory space and run slow, ScrollZ only takes a couple of extra kilobytes compared to stock ircII client yet runs faster than any ircII script. This was accomplished by using C code instead of ircII scripting language. This reduces memory and CPU usage and code tends to run way faster.

A `scheme' interpreter designed for writing system programs. Scsh has a high-level process notation for doing shell-script like tasks: running programs, establishing pipelines and I/O redirection. Scsh embeds this process notation within a full Scheme implementation. The process notation is realized as a set of macro definitions, and is carefully designed to allow full integration with standard Scheme code. Scsh isn't Scheme-like; it is Scheme. At the scripting level, scsh also has an Awk design, also implemented as a macro that can be embedded inside general Scheme code. Scsh additionally provides the low-level access to the operating system normally associated with C. The current release provides full access to POSIX, plus important non-POSIX extensions, such as complete sockets support. "Complete POSIX" means: fork, exec & wait, sockets, full read, write, open & close, seek & tell, complete file-system access, including stat, chmod/chgrp/chown, symlink, FIFO & directory access, tty & pty support, file locking, pipes, select, file-name pattern-matching, time & date, environment variables, signal handlers, and more. Please be aware that several of the other scheme implementations being distributed as Debian GNU/Linux packages also provide much of the similar system programming functionality. It is wisest to try them all and explore. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Small Computer Systems Interface (SCSI) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
SCSI (pronounced scuzzy) stands for Small Computer System Interface. SCSI is a ribbon, a specification, and an electronic protocol for communication between devices and computers. Like your IDE ribbons, SCSI ribbons can connect to their own SCSI hard disks. SCSI ribbons have gone through some versions to make SCSI faster, the latest ``Ultra-Wide'' SCSI ribbons are thin, with a dense array of pins. Unlike your IDE, SCSI can also connect tape drives, scanners, and many other types of peripherals. SCSI theoretically allows multiple computers to share the same device, although I have not seen this implemented in practice. Because many UNIX hardware platforms only support SCSI, it has become an integral part of UNIX operating systems. SCSIs also introduce the concept of LUNs (which stands for Logical Unit Number), Buses, and ID. These are just numbers given to each device in order of the SCSI cards you are using (if more than one), the SCSI cables on those cards, and the SCSI devices on those cables--the SCSI standard was designed to support a great many of these. The kernel assigns each SCSI drive in sequence as it finds them: /dev/sda, /dev/sdb, and so on, so these details are usually irrelevant. An enormous amount should be said on SCSI, but the bare bones is that for 90% of situations, insmod <pci-scsi-driver> is all you are going to need. You can then immediately begin accessing the device through /dev/sd? for disks, /dev/st? for tapes, /dev/scd? for CD-ROMs, or /dev/sg? for scanners. [Scanner user programs will have docs on what devices they access.] SCSIs often also come with their own BIOS that you can enter on startup (like your CMOS). This will enable you to set certain things. In some cases, where your distribution compiles-out certain modules, you may have to load one of sd_mod.o, st.o, sr_mod.o, or sg.o, respectively. The core scsi_mod.o module may also need loading, and /dev/ devices may need to be created. From Rute-Users-Guide http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Add or remove SCSI devices by rescanning the bus. scsiadd allows you to add or remove SCSI devices without having to restart the computer. This is *NOT* a substitute for powering down to connect or disconnect hardware unless it's specifically designed to be hot swappable. Use it to enable the external SCSI drive you only use occasionally so is powered off when the machine first boots, or to rescan the bus after moving hot-swap drives around. scsiadd will also try to prevent you from doing anything to disrupt drive names that are in use. Similar functionality is available by echoing text to /proc/scsi/scsi From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Collection of tools for SCSI hardware management This package is a collection of tools for manipulating SCSI hardware: scsiinfo: displays SCSI drive low-level information and modifies SCSI drive settings, scsidev: makes permanent SCSI LUN -> devicename connections, scsifmt: low-level SCSI formatter, sraw: benchmarks raw SCSI I/O rates bypassing the buffer cache, scsistop: low-level SCSI drive start/stop program, scsi-spin: program to manually spin up and down a SCSI device. Be aware that these tools require some knowledge of what are they doing to be used properly, not causing damage to your system.

Fly aircraft to Search (for) and Rescue people in distress. Tired of scores indicating things destroyed or lives snuffed? Try something different -- fly a helicopter around and rescue people in distress. If you were in trouble wouldn't you want someone to rescue you? This game is intended for players of all audiences, but especially for mature players who want to get away from the violence and still retain a level of precise challenge. Flight difficulty can be lowered for beginners (regardless of mission type), and graphics minimized to suit slower computers (minimum Pentium 166 with no graphics acceleration). This package has been configured to depend on libjsw for joystick support and libY2 for sound support. However, neither a joystick nor sound support is necessary to enjoy the game. http://wolfpack.twu.net/SearchAndRescue/ From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

(alt. `security by obscurity') A term applied by hackers to most OS vendors' favorite way of coping with security holes -- namely, ignoring them, documenting neither any known holes nor the underlying security algorithms, trusting that nobody will find out about them and that people who do find out about them won't exploit them. This "strategy" never works for long and occasionally sets the world up for debacles like the RTM worm of 1988 (see Great Worm), but once the brief moments of panic created by such events subside most vendors are all too willing to turn over and go back to sleep. After all, actually fixing the bugs would siphon off the resources needed to implement the next user-interface frill on marketing's wish list -- and besides, if they started fixing security bugs customers might begin to expect it and imagine that their warranties of merchantability gave them some sort of right to a system with fewer holes in it than a shotgunned Swiss cheese, and then where would we be? Historical note: There are conflicting stories about the origin of this term. It has been claimed that it was first used in the Usenet newsgroup in comp.sys.apollo during a campaign to get HP/Apollo to fix security problems in its Unix-clone Aegis/DomainOS (they didn't change a thing). ITS fans, on the other hand, say it was coined years earlier in opposition to the incredibly paranoid Multics people down the hall, for whom security was everything. In the ITS culture it referred to (1) the fact that by the time a tourist figured out how to make trouble he'd generally gotten over the urge to make it, because he felt part of the community; and (2) (self-mockingly) the poor coverage of the documentation and obscurity of many commands. One instance of deliberate security through obscurity is recorded; the command to allow patching the running ITS system (escape escape control-R) echoed as $$^D. If you actually typed alt alt ^D, that set a flag that would prevent patching the system even if you later got it right.

a satellite location program Seesat5 uses the NORAD sgp4 algorithm to compute the location of a satellite. Many different filtering methods are provided by Seesat5 so that only those satellites that might actually be viewed are presented in the report. This report includes bearing and elevation with respect to the observer's location as well as other information of interest to the observer. Although an observer would find no use for it, the program can be made to report the location even when it is below the horizon. For radio satellites like the Oscar series knowing when it comes above the horizon is some of the interesting information this program can provide.

A lexer, parser-generator, and parser written in elisp The Semantic Bovinator's goal is to provide an intermediate API for authors of language agnostic tools who want to deal with languages in a generic way. It also provides a simple way for Mode Authors, who are experts in their language, to provide a parser for those tool authors, without knowing anything about those tools. The Semantic Bovinator is made up of these important pieces: - lexer: Converts a language into a token stream - parser: Converts a token stream into a stream of nonterminals defined by the language. - parser-generator: Converts a language definition into a table usable by the parser. (Written using the Semantic Bovinator) - Language Definitions: Parsers already existing for the parser generator language (Bovine Normal Form), Emacs Lisp, and C. - speedbar browser: Code for browsing a generated nonterminal list with Speedbar. - Documentation generator: Identifies inline documentation in source code, and can convert it to texinfo. It can also create inline documentation. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Simple Asynchronous File Transfer Sendfile is an asynchronous file transfer service for the Internet, like the sendfile facility in Bitnet: Any user A can send files to another user B without B being active in any way. The existing standard file transfer (ftp) is a synchronous service: The user must have access to an account on the sending and on the receiving site, too. Sendfile for Unix, which is an implementation of the SAFT protocol (Simple Asynchronous File Transfer) now offers you a true asynchronous file transfer service for the Internet. Virtually any form of file can be sent, including encrypted ones. The SAFT protocol will be submitted as an RFC in the near future.

A commandline tool to allow sending arbitrary IP packets. SendIP has a large number of command line options to specify the content of every header of a RIP, TCP, UDP, ICMP or raw IPv4 and IPv6 packet. It also allows any data to be added to the packet.

A powerful, efficient, and scalable Mail Transport Agent. Sendmail is an alternative Mail Transport Agent (MTA) for Debian. It is suitable for handling sophisticated mail configurations, although this means that its configuration can also be complex. Fortunately, easy thing can be done easily, and complex things are possible, even if not easily understood ;) Sendmail is the *ONLY* MTA with a Turing complete language under the covers ! Sendmail provides Security and SPAM/UCE/UBE protection via several means: - STARTTLS(SSL) RFC2487 encryption for mail reception/delivery. - STARTTLS(SSL) authentication (certificate based) for access/relay control. - SMTP AUTH (SASL/PAM) authentication for access/relay control. - ACCESS database (by IP/host) for access/relay control. - Use of varied Realtime Blackhole Lists (RBL) to prevent access. - Integration of LOGCHECK rules to fine-tune logging. - Inboard POSIX Regular Expression processing of *all* headers. - Ability (via MILTER) to scan/change headers *and* body of *ALL* mail A site may utilize zero, one, or more MILTERs. - Reduced SUID exposures by running SGID smmsp/mail where possible. Sendmail provides Performance and Scalability by: - Allowing multiple queues, with the ability to tune both interval and queue runners on a queue by queue basis. - Providing (a Debian exclusive) an easy to configure means of queue-aging to improve throughput by not continually retrying failed deliveries. - Allowing most all maps/databases to be obtained via LDAP; reducing the number of used databases and simplifying the maintenance of Sendmail. - Reducing the file I/O where possible by buffering files in memory. Sendmail provides site enhanced site configuration/customization by: - Allowing the listener (usually port 25) to run as a daemon or via INETD. - Allowing the queue runner (mail delivery) to run as a daemon or via CRON. - Automagically updating configuration and databases on upgrades. - Providing a Turing complete language for site customization of mail handling. - Providing a means (MILTER) for a site to scan/change all email - both incoming and outgoing. A site can write their own MILTER, or may use any of those found on internet. To write your own MILTER, you'll need to install the optional milter-dev package. - Providing extensive documentation via the sendmail-doc (optional) package. - Providing an inboard Mail Delivery Agent (MDA) (mail.local), but supporting procmail, mailagent, maildrop, or deliver automatically if installed. Sendmail will also deliver to anythings else (cyrus, etc) if asked to. Sendmail includes *no* Mail User Agents (MUA), you'll have to pick from the plethora of available MUAs (pine, mutt, vm, etc.) This package supports REGEX, DB, NIS, NIS+, LDAP, DNS, HESIOD maps, and has enabled TCPWrappers, IPv6, LockFile, SMTP AUTH(SASL), STARTTLS(SSL). From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Sendmail is a popular e-mail server package. By most estimates, well over half of all e-mail flowing through the Internet goes through a Sendmail system. Sendmail is open-source software. Key point: Sendmail is an MTA (Message Transfer Agent). This means that Sendmail only transfers e-mail to other MTAs. Client programs (like Outlook, Eudora, Pine) will use SMTP to hand e-mail to Sendmail for transmission over the Internet, but they can't use SMTP to read e-mail. Instead, when Sendmail receives e-mail destined for the local machine, it must hand it off to some other software package. In the most common situation, Sendmail will save incoming messages in mbox format to /var/spool/mail for each user, and other programs will allow users to retrieve e-mail from those files. History: In 1989, Morris Worm exploited Sendmail bugs as one technique to spread itself. Sendmail is an ancient software package on the Internet, which results in a high-degree of complexity for backwards compatibility. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Sendmail sends a message to one or more recipients, routing the message over whatever networks are necessary. Sendmail does inter-network forwarding as necessary to deliver the message to the correct place. Sendmail is not intended as a user interface routine; other programs provide user-friendly front ends; sendmail is used only to deliver pre-formatted messages. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The Sendmail program is a very widely used Mail Transport Agent (MTA). MTAs send mail from one machine to another. Sendmail is not a client program, which you use to read your email. Sendmail is a behind-the-scenes program which actually moves your email over networks or the Internet to where you want it to go. If you ever need to reconfigure Sendmail, you will also need to have the sendmail.cf package installed. If you need documentation on Sendmail, you can install the sendmail-doc package.

A computer system that manages files, services, and access to resources on a network. From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A computer, or a software package, that provides a specific kind of service to client software running on other computers. The term can refer to a particular piece of software, such as a WWW server, or to the machine on which the software is running, e.g. "Our mail server is down today, that's why e-mail isn't getting out." A single server machine can (and often does) have several different server software packages running on it, thus providing many different servers to clients on the network. Sometimes server software is designed so that additional capabilities can be added to the main program by adding small programs known as servlets.

Especially the CPU power reduction cuts down on most temperature-related problems on many motherboards. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Control the behaviour of your cdrom device This program allows you to control the behaviour of your Linux cdrom player. You'll need a cdrom device that complies to the new interface defined in linux/Documentation/cdrom/cdrom-standard.tex. For kernel 2.0 this is only the cm206 drive, for kernel 2.1 this includes IDE and SCSI drives. You can control: auto close, auto eject, medium type checking and tray locking. You can get information on the volume name of cdroms and other data, and you can set the speed of your drive and choose a disc from a jukebox. In order to fully exploit the possibilities, you'll need libc6 and a recent version of the the linux kernel, but you will get decent error behaviour in return. Expect a message "No medium found" if you attempt to mount an empty drive or "Wrong medium type" if you try to mount an audio disc, instead of a whole load of kernel error messages. The source of this package may be an example for cdrom player program developers that wish to exploit the features of the new cdrom interface.

SETI@Home Client (install package) SETI@home is a scientific experiment that harnesses the power of hundreds of thousands of Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data. There's a small but captivating possibility that your computer will detect the faint murmur of a civilization beyond Earth. SETI@Home is only distributed in binary form and the correct unix tar ball for your architecture has to be downloaded from http://setiathome.ssl.berkeley.edu/unix.html and placed in $TMPDIR (or /tmp if $TMPDIR is not defined). This installer package will automagically wget (if wget is installed) the right tarball and install the program, if the target debian linux architecture is one of the following: x86, alpha, sparc, powerpc or hppa.

Controls configuration of serial ports. Set and/or report the configuration information associated with a serial port. This information includes what I/O port and which IRQ a particular serial port is using. This version has a completely new approach to configuration, so if you have a setup other than the standard ttyS0 and 1, you will have to get your hands dirty. By default, only COM1-4 are configured by the kernel, using IRQ 3 and 4. If you have other serial ports (such as an AST Fourport card), or if you have mapped the IRQs differently (perhaps COM3 and 4 to other IRQs to allow concurrent access with COM1 and 2) then you must have this package.

UNIX programs that can be run by a user, but which have root privileges. Key point: In theory, setuid programs can only be installed by root, and they are considered as part of the operating system, because they inherently bypass security checks and must verify security themselves. A typical example is the passwd command, which a user runs in order to change his/her password. It must be setuid, because it changes files only root has access to, but yet it must be runnable by users. Key point: In practice, setuid programs often have bugs that can be exploited by logged in users. Key point: As part of hardening a system, the administrator should scour the system and remove all unnecessary setuid programs. Linux find / -type f -perm +6000 -exec ls -l {} \; Solaris find / -type f \( -perm -4000 -o -perm -2000 \) -exec ls -l {} \; In order to remove the suid bit, you can use the command chmod -s filename. Removing the suid bit will disable a lot of programs. Two programs that really need to have this bit turned on are /usr/bin/passwd, which users run to change their passwords, and /bin/su, which elevates a normal user to super user (when given the correct password). Key point: Some programs are really setguid which only changes the group context rather than the user context. Key point: Windows doesn't have the concept of setuid. Instead, RPC is used whereby client programs (run by users) contact server programs to carry out the desired task. For example, in order to change the password, the client program asks the SAM to do it on behalf of the user. Thus, whereas UNIX requires a myriad of client programs to verify credentials and be written securely, Windows only requires a few server programs to do the same. Key point: A common way to backdoor a system is to place a SUID program in the /tmp directory. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

convert DocBook SGML source into HTML using DSSSL A text-formatting package based on SGML (Standard Generalized Markup Language), which allows you to produce TeX/DVI/PS/PDF, HTML, RTF, and plain ASCII (currently via w3m by default) from a single source with other recommended and suggested packages; due to the flexible nature of SGML, many other target formats are possible. This tool can not handle DocBook XML yet. For DocBook SGML only. HTML can be generated without any other Debian text processing package, but for the other formats the appropriate packages have to be installed. You need to install lynx or w3m for ASCII text output (w3m is the default txt backend). Also jadetex is required for PS and PDF, and linuxdoc-tools for ld2db conversion. This system is tailored for writing technical software documentation, an example of which are the Linux HOWTO documents. However, there is nothing Linux-specific about this package; it can be used for many other types of documentation on many other systems. It should be useful for all kinds of printed and online documentation. The package was formerly called linuxdoc-sgml because it originates from the Linux Documentation Project (LDP).

Super High Aperture [LCD] (LCD) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
SHA-1 is a popular hash algorithm. It converts an input file or message into a "unique" 160-bit fingerprint. This fingerprint is believed to be "unique"; while it is theoretically possible that two inputs could hash to the same fingerprint, it is nearly statistically impossible. Contrast: SHA-1 is currently (year 2001) considered to be the strongest hash function available. It has a larger size (160-bits vs. 128-bits) and has underground thorough scrutiny without discovery of weaknesses (such as MD5). On the other hand, it is one of the slower hash algorithms. History: SHA-1 is a slight variation of SHA. It adds a one-bit shift at one stage in order to overcome a theoretical weakness. SHA was based upon MD4, enhanced to overcome known weaknesses and increase the length to 160-bits. See also: integrity From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates an npasswd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel and usermod commands are used for managing user accounts. The groupadd, groupdel andgroupmod commands are used for managing group accounts.

toggle shadow passwords on and off From whatis http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
UNIX was designed around the concept of making the encrypted form of passwords readable by everyone. These passwords were stored in the /etc/passwd file, along with the full account information. It was thought to be secure because the passwords were stored in an encrypted format within this file. However, this is not secure in practice because users tend to choose easily guessable passwords. A program called crack was developed that would guess dictionary words (/usr/dict) and then attempt to brute force the passwords. On an average UNIX system, 90% of all passwords could be cracked with a few days worth of computing time. In order to solve this problem, a "shadow" password file was developed. The encrypted passwords are removed from the normal /etc/passwd and placed in a special file (usually /etc/shadow) that is only readable by root. The remaining account information is left in the original password file for backwards compatibility. Example: The following is a table of typical locations for the shadowed passwords: AIX 3 /etc/security/passwd or /tcb/auth/files// A/UX 3.0s /tcb/files/auth/?/ BSD4.3-Reno /etc/master.passwd ConvexOS 10 /etc/shadpw ConvexOS 11 /etc/shadow DG/UX /etc/tcb/aa/user/ EP/IX /etc/shadow HP-UX /.secure/etc/passwd IRIX 5 /etc/shadow Linux /etc/shadow OSF/1 /etc/passwd[.dir|.pag] SCO Unix #.2.x /tcb/auth/files// SunOS4.1+c2 /etc/security/passwd.adjunct SunOS 5.0 /etc/shadow System V Release 4.0 /etc/shadow System V Release 4.2 /etc/security/* database Ultrix 4 /etc/auth.dir or /etc/auth.pag UNICOS /etc/udb Key point: In the old days, most remote attacks against UNIX were directed at the /etc/passwd file. For example, the most common form of the phf would be to grab the password file. As password shadowing becomes more common, such attacks are increasingly being pointed at the shadow password file instead.

The Shapecfg program configures and adjusts traffic shaper bandwidth limiters. Traffic shaping is setting parameters or limits on bandwidth consumption, to which network traffic should conform. To use Shapecfg,you must have also installed the kernel which supports the shaper module (kernel versions 2.0.36 or later and late 2.1.x kernels).

Traffic Shaper for Linux The traffic shaper for Linux configures and adjusts traffic shaper bandwidth limiters. Traffic shaping means setting parameters or limits to which network traffic should conform - that is, setting limitations on bandwidth consumption. See README.shaper for more details. An init script which sets up traffic shaping using class-based queueing is also provided. This can be used to build smart bandwidth shapers which know about TCP/IP. See README.cbq for more details. The kernel support needed to use either of these facilities is described in README.Debian. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A user-mode traffic shaper for tcp-ip networks. Shaperd is a user-mode program that can shape traffic passing through a Linux box.

Configuration and Release management using AtFS. ShapeTools is a collection of programs to support software configuration management in an UNIX environment. It consists of a set of version and attribute control commands, and a configuration interpreter and build tool ("shape"). The toolkit is integrated on top of the Attributed File System (AtFS). ShapeTools is designed to live meaningfully together with any other UNIX tool operating on regular files. This distribution also contains a prototype for a comprehensive change control and release management system designed to manage the evolution of system releases in multi programmer software development efforts.

create shell archives From whatis http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
/shar'ki:v/ n. [Unix and Usenet; from /bin/sh archive] A flattened representation of a set of one or more files, with the unique property that it can be unflattened (the original files restored) by feeding it through a standard Unix shell; thus, a sharchive can be distributed to anyone running Unix, and no special unpacking software is required. Sharchives are also intriguing in that they are typically created by shell scripts; the script that produces sharchives is thus a script which produces self-unpacking scripts, which may themselves contain scripts. (The downsides of sharchives are that they are an ideal venue for Trojan horse attacks and that, for recipients not running Unix, no simple un-sharchiving program is possible; sharchives can and do make use of arbitrarily-powerful shell features.) Sharchives are also commonly referred to as `shar files' after the name of the most common program for generating them. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

The idea that many people share the same password or key. Shared secrets are widely use because they are easy: there is simply one password to give out. On the other hand, the more widely secrets are shared, the more likely it will become compromised. In fact, many people believe that even sharing a secret among two people is extremely risky, where the proper solution is using public keys to distribute a randomly generated key only valid for the particular message. Example: DVD movies are encrypted with a randomly generated key. This key is then is then encrypted multiple times with hundreds of different keys. Every DVD player vendor owns one of these keys and imbeds it in their device, thus allows that player to decrypt the movie. (Presumably, if one of the keys is compromised, future movies can be generated without the offending key, causing players based upon that key to become obsolete). However, there is no good way to protect these keys, even though they are in hardware. In late 1999, students in Europe where able to break one of these keys (the Xing software DVD player), and from there they were able to break the majority of the other keys. (These keys only used 40-bit encryption, so breaking one key in the software player allowed a known-plaintext attack). From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

shar, unshar, uuencode, uudecode `shar' makes so-called shell archives out of many files, preparing them for transmission by electronic mail services. `unshar' helps unpacking shell archives after reception. Other related utility programs help with other tasks. `uuencode' prepares a file for transmission over an electronic channel which ignores or otherwise mangles the eight bit (high order bit) of bytes. `uudecode' does the converse transformation.

The sharutils package contains the GNU shar utilities, a set of tools for encoding and decoding packages of files (in binary or text format) in a special plain text format called shell archives (shar). This format can be sent through email (which can be problematic for regular binary files). The shar utility supports a wide range of capabilities (compressing, uuencoding, splitting long files for multi-part mailings, providing checksums), which make it very flexible at creating shar files. After the files have been sent, the unshartool scans mail messages looking for shar files. Unshar automatically strips off mail headers and introductory text and then unpacks the sharfiles. Install sharutils if you send binary files through email very often. From Mandrake 9.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

One of several command line interfaces available on Unix machines, some common shells include Bourne shell, ksh, and tcsh. From KADOWKEV http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The default command-line interface on UNIX systems. Key point: This is similar to the "Command Prompt" or incorrectly named "DOS Prompt" on Windows systems. Key point: Many systems pass filenames along with commands directly to the shell. Hackers can exploit this by sending special shell characters (like the pipe | character) as part of filenames in order to execute their own commands. This is an example of an input validation exploit. Examples of this are web-servers, PERL scripts, and CGI scripts. Key point: The most popular shell among hackers is probably "bash", the shell from GNU that ships with Linux. (Culture: The original shell on UNIX is known as the "Bourne Shell", named for its creator. The acronym "bash" means "Bourne Again SHell", reflecting that fact that it is a rewrite of that shell). Key point: Retrieving someone's .bash_history file is a common attack against UNIX machines. Several embedded systems have shipped such that the file http://raq.robertgraham.com/~root/.bash_history could be retrieved via the web. Key point: The holy grail of UNIX hacking is to somehow obtain (or re-obtain) a root shell. In other words, the hacker wants to get a command-line on the victim system in order to carry out any task. For this reason, buffer overflow exploits often contain what is called "shell code". When the victim process is running with root privileges, the buffer-overflow will cause that process to begin running a shell. For example, an exploit might send a long password containing the shell code to an FTP server, converting the TCP connection to the FTP server into a full command-prompt from which any program can be launched. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
[orig. Multics n. techspeak, widely propagated via Unix] 1. [techspeak] The command interpreter used to pass commands to an operating system; so called because it is the part of the operating system that interfaces with the outside world. 2. More generally, any interface program that mediates access to a special resource or server for convenience, efficiency, or security reasons; for this meaning, the usage is usually `a shell around' whatever. This sort of program is also called a `wrapper'. 3. A skeleton program, created by hand or by another program (like, say, a parser generator), which provides the necessary incantations to set up some task and the control flow to drive it (the term driver is sometimes used synonymously). The user is meant to fill in whatever code is needed to get real work done. This usage is common in the AI and Microsoft Windows worlds, and confuses Unix hackers. Historical note: Apparently, the original Multics shell (sense 1) was so called because it was a shell (sense 3); it ran user programs not by starting up separate processes, but by dynamically linking the programs into its own code, calling them as subroutines, and then dynamically de-linking them on return. The VMS command interpreter still does something very like this. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
vi. [Unix] To spawn an interactive subshell from within a program (e.g., a mailer or editor). "Bang foo runs foo in a subshell, while bang alone shells out." From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Shell Scripting and hence computer programming is merely the idea of getting a number of commands to be executed, that in combination do some unique powerful function. From Rute-Users-Guide http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
When a hackers successfully exploit vulnerabilities like buffer overflows, they will typically open a shell at the end of the exploit. With a command-line shell, the hacker will then be able to carry out any task they desire. However, opening shells within buffer overflow exploits can be difficult. Therefore, hackers often maintain libraries of "shellcode": code fragments for various operating systems that can be pasted into buffer overflow exploits. Key point: One of the difficulties in writing shellcode is that need to pass through filters. For example, when exploiting a bug in an SMTP server, you may find that the server strips the high-order bit from all bytes (i.e. will pass text but not binary). Therefore, all bytes between 0x00-07F will pass through, but not 0x80-0xFF. Alternately, a big limitation is systems that won't pass nul characters (0x00) because they terminate strings in functions like strcpy(). Therefore, when a hacker picks shellcode to append to their script, they must be fully aware of the limitations of the system they are dealing with. Key point: When creating new shellcode, create a C program that calls something like "system("/bin/sh");" or "execve("/bin/sh",0,0);" and grab the assembly output. At that point, pare it down to what you need. This requires extensive knowledge of assembly, needless to say. Key point: Sometimes you won't be able to grab a shell, so you have to create the exploit script to run a command. Typical choices of commands would be those that change passwords, add accounts, or in some fashion open up some other hole on the system. Key point: The vast majority of buffer overflow attacks will execute /bin/sh. Therefore, by simply removing this program (or replacing it with something that double-checks what's being done), you can protect yourself against many 0-day exploits.

A tool for scanning a UNIX NFS servers to see what directories it is sharing/exporting and to whom. There are two basic forms of this command: showmount victim Shows which machines are logged onto the victim NFS server. showmount -e victim Shows which directories are being exported, and which groups can log on. Entries marked as (everyone) allow anybody to log on. Key point: This command used the rpc.mountd protocol (RPC program number 100005). On most systems, these commands do not require authentication, which means that anybody can run them. The showmount command with no arguments equates the MOUNTPROG_DUMP procedure, whereas the -e option equates to the MOUNTPROG_EXPORT procedure. This protocol is extremely light-weight, only two packets in each direction are needed: one for the portmap, and one for the procedure call. Contrast: Similar capabilities exist on Windows for Microsoft's SMB protocols. The net view \\victim command on Windows will view the shares that the victim is exporting.

A secure, encrypted version of HTTP used for financial transactions and other private information sent via the Internet. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
An extension of the World Wide Web's HyperText Transport Protocol (HTTP) that supports secure commercial transactions on the Web. Secure HTTP provides this support in two ways by assuring vendors that the customers attempting to buy the vendors' wares are who they say they are (authentication) and by encrypting sensitive information, such as credit-card numbers , so that it cannot be intercepted while en route. Secure HTTP was developed by Enterprise Integration Technology (EIT) and the National Center Supercomputing Applications (NCSA), with subsequent commercial development by Terisa system. Netscape communications developed a competing security technology , the Secure Sockets Layer (SSL) protocol. The two security protocols are incompatible, and for a time it was feared that no single widely accepted security protocol would emerge. In early 1995, however Netscape invested heavily in Terisa Systems and announced that it would integrate Secure HTTTP and SSL to provide the Web community with a single security protocol that will work with any security-capable browser.

/sig blok/ n. [Unix; often written `.sig' there] Short for `signature', used specifically to refer to the electronic signature block that most Unix mail- and news-posting software will automagically append to outgoing mail and news. The composition of one's sig can be quite an art form, including an ASCII logo or one's choice of witty sayings (see sig quote, fool file); but many consider large sigs a waste of bandwidth, and it has been observed that the size of one's sig block is usually inversely proportional to one's longevity and level of prestige on the net.

Software interrupts sent to a program to indicate that an important event has occurred. The events can vary from user requests to illegal memory access errors. Some signals, like the interrupt signal, indicate that a user has asked the program to do something that is not in the usual flow of control. http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
used to inform processes of unexpected external events such as a time out or forced termination of a process. A signal consists of prescribed message with a default action embedded in it. Each signal has a unique number associated with it. An example is SEGV, segmentation violation. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
In anti-virus and intrusion detection systems, a signature is a pattern that the system will look for when scanning files or network traffic. (Note: this term is unrelated to digital signatures). Key point: Marketing forces often mean that companies have to fill their products with useless signatures. Don't be impressed because one product has more signatures than another. Key point: One of the key goals of hacking is to evade signature detection. Virus writers attempt to encrypt their viruses, whereas remote hackers attempt to alter the networking protocol so that it has the same effect, but a different pattern on the wire.

create and render 3-d scenes This is SIPP, the SImple Polygon Processor, version 3.1. SIPP is a library for creating 3-dimensional scenes and rendering them using a scan-line z-buffer algorithm. A scene is built up of objects which can be transformed with rotation, translation and scaling. The objects form hierarchies where each object can have arbitrarily many subobjects and subsurfaces. A surface is a number of connected polygons which are rendered with either Phong, Gouraud or flat shading. An image can also be rendered as a line drawing of the polygon edges without any shading at all. The library supports texture mapping with textures in up to 3-dimensions and automatic interpolation of texture coordinates. Simple anti-aliasing can be performed through oversampling. A scene can be illuminated by an arbitrary number of light sources and a number of different light sources are availaible. The light from some of them are capable of casting shadows of objects. A basic shading algorithm is provided with the library, but the user can also use his own shading algorithms for each surface to produce special effects. Objects can have varying degree of transparency, controlled by the shader. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Serial Line Internet Protocol (Internet, RFC 1055), "SL/IP" From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Serial Line Internet Protocol - A communication method that allows a personal computer to connect directly to the Internet using a standard telephone line. It preceded PPP as the means through which access to the Internet could be achieved. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A standard for using a regular telephone line (a serial line) and a modem to connect a computer as a realInternet site. SLIP has largely been replaced by PPP. From Matisse http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Allows a computer to connect to the Internet using a modem and telephone line--similar to PPP. Users then navigate the Internet using software on their own computer. This is in contrast to using a dialup teminal connection, where a user is forced to navigate the Net using a text-based set of menus. From Glossary of Distance Education and Internet Terminology http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Predecessor of PPP. Allows a user to connect to the Internet directly over a high-speed modem. From Glossary of Distance Education and Internet Terminology http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
One of two standards specifying how a workstation or personal computers can link to the Internet by means of a dialup connection (the other standard is the Point-to-Point Protocol [PPP] . SLIP defines the transport of data packets through an asynchronous telephone line. Therefore, SLIP enables computers not directly connected to local area networks (LANs) to be fully connected to the Internet. This mode of connectivity is far superior to shell access (a dialup, text-only account on a UNIX computer) because it enables you to use the Internet tools of your choice (such as a graphical Web browser to run more than one Internet application at a time and to download data directly to your computer, with no intermediate storage required. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
SLIP/PPP emulator using a dial up shell account Slirp is a TCP/IP emulator which turns an ordinary shell account into a (C)SLIP/PPP account. This allows shell users to use all the funky Internet applications like Netscape, Mosaic, CUSeeMe, etc. Please note that maybe your ISP really doesn't like you using slirp, because they want to charge more for a ppp connection, so use it at your own risk.

Programs for counting physical source lines of code (SLOC) SLOCCount (pronounced "sloc-count") is a suite of programs for counting physical source lines of code (SLOC) in potentially large software systems (thus, SLOCCount is a "software metrics tool" or "software measurement tool"). SLOCCount can count physical SLOC for a wide number of languages; listed alphabetically, they are: Ada, Assembly, awk, Bourne shell, C, C++, C shell, Expect, Fortran, Java, lex/flex, LISP (including Scheme), Modula3, Objective-C, Pascal, Perl, PHP, Python, sed, TCL, and Yacc. SLOCCount can automatically determine if a file is a source code file or not, and if so, which language it's written in. As a result, you can analyze large systems completely automatically. SLOCCount also includes some report-generating tools to collect the data generated and present it in several different formats.

The GNU Eiffel Compiler SmallEiffel is a compiler for the Eiffel language, which is a pure object-oriented language providing strong type-checking and based on the concept of 'design by contract'. It allows multiple inheritance and does it well. Design-by-contract means that a class guarantees that certain conditions will always hold, and that a routine guarantees certain results given certain specified inputs. The rules for inheritance mean that contracts can be relied on even when classes are reused through inheritance. The Eiffel language is described and defined in the book "Eiffel: The Language" by Bertrand Meyer. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A high-level declarative programming language and programming environment that treates computations as objects that send messages to one another. SmallTalk encourages the programmer to define objects in terms relevant to the intended application. The language is highly extensible because it enables you to create objects, which can be reused, quite easily. SmallTalk inspired HyperTalk, the software command language of HyperTalk, an application provided with every Macintosh produced since 1987. In this new guise, SmallTalk fulfills its goal of making programming more accessible; tens of thousand of Macintosh users have learned how to program in HyperTalk.

A smart-card looks like a credit-card but contains an embedded microprocessor. The gold contact pad with roughly 8 contact points is visible on the outside of the card. As of the year 2000, typical circuits consisted of an 8-bit microprocessor running at 5MHz, 1K of RAM, and 16K of ROM with a 9.6-kbps half-duplex interface. (Much of the design of AES focused on being able to run within these stringent requirements). Key point: Whereas the data on the magnetic strip of a credit-card can be easily read or changed, smart-cards are designed to be tamper proof. Example: All Germans have a smart-card for health insurance. As of 2001, smart-cards have been popular in Europe for about a decade, but are still mostly unknown in the United States. Example: The tamper-proof features make it popular for authentication in both physical security and infosec uses. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
n. 1. A terminal that has enough computing capability to render graphics or to offload some kind of front-end processing from the computer it talks to. The development of workstations and personal computers has made this term and the product it describes semi-obsolescent, but one may still hear variants of the phrase `act like a smart terminal' used to describe the behavior of workstations or PCs with respect to programs that execute almost entirely out of a remote server's storage, using local devices as displays. 2. obs. Any terminal with an addressable cursor; the opposite of a glass tty. Today, a terminal with merely an addressable cursor, but with none of the more-powerful features mentioned in sense 1, is called a dumb terminal. There is a classic quote from Rob Pike (inventor of the blit terminal): "A smart terminal is not a smartass terminal, but rather a terminal you can educate." This illustrates a common design problem: The attempt to make peripherals (or anything else) intelligent sometimes results in finicky, rigid `special features' that become just so much dead weight if you try to use the device in any way the designer didn't anticipate. Flexibility and programmability, on the other hand, are really smart. Compare hook. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Introduction This is the SMB HOWTO. This document describes how to use the Server Message Block (SMB) protocol, also called the Session Message Block, NetBIOS or LanManager protocol, with Linux using Samba. Although this document is Linux-centric, Samba runs on most Unix-like operating systems. This document is maintained by David Wood ( dwood@plugged.net.au). Additions, modifications or corrections may be mailed there for inclusion in the next release. Much more Samba documentation is available at the Samba Web site, located at http://www.samba.org/. There is a tremendous amount of information there; please have a look before asking for help! You also might try the comp.protocols.smb newsgroup. The SMB protocol is used by Microsoft Windows 3.11, NT and 95/98 to share disks and printers. Using the Samba suite of tools by Andrew Tridgell ( Andrew.Tridgell@anu.edu.au), UNIX (including Linux) machines can share disk and printers with Windows hosts. The smbfs tools by Paal-Kr. Engstad ( engstad@intermetrics.com) and Volker Lendecke ( lendecke@namu01.gwdg.de) enable Unix machines to mount SMB shares from Windows or Samba hosts. There are four basic things that one can do with Samba: Share a Linux drive with Windows machines. Access an SMB share with Linux machines. Share a Linux printer with Windows machines. Share a Windows printer with Linux machines. All of these are covered in this document, plus a few other odds and ends. Disclaimer: The procedures and scripts either work for the author or have been reported to work by the people that provided them. Different configurations may not work with the information given here. If you encounter such a situation, please e-mail the author with suggestions for improvement in this document. Please note that for Windows 3.x machines to access SMB shares, they must have a TCP/IP stack and the Win32s DLLs. Both of these are available on Microsoft's Web site ( http://www.microsoft.com). As of the writing of this version of the HOWTO, Microsoft are reportedly requiring a subscription to the Microsoft Software Developers Network (MSDN) to download the TCP/IP-32 stack for Windows 3.x from their Web site. Since this software used to be free, many older copies are in existance and may be acquired from friends and user group contacts.

SMB is the protocol used by Microsoft for file and print sharing. SMB stands for Server Message Block, though that doesn't really mean anything. SMB runs on top of NetBIOS, though in Win2k it can bypass NetBIOS. History: SMB was originally developed for DOS machines. It was later upgraded so that OS/2 machines could act as servers for DOS machines. The protocol was later upgraded for Windows (Wfw = Windows for Workgroups) and Windows NT. Still later upgrades have been added for Windows 2000. This constant evolution and need for backwards compatibility has led to many security holes within the protocol. The most severe is the need for "LAN Manager" authentication. Key point: SMB is an application layer protocol and can run over many different transports, including TCP/IP. A common problem is that home-users enable SMB over TCP/IP, allowing anybody on the Internet to access their hard-disk. They should instead install a local-only transport such as NetBEUI for SMB, which will allow file access among local machines, but not remote machines across the Internet. Key point: SMB-sniffers can read the encrypted password info off the wire and send them to password crackers. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

In particular it includes the command line utilities smbclient, smbtar, and smbspool.

mount and umount commands for the smbfs (for kernels >= than 2.2.x) Smbfs is a filesystem which understands the SMB protocol. This is the protocol Windows for Workgroups, Windows NT or LAN Manager use to talk to each other. It was inspired by samba, the program by Andrew Tridgell that turns any unix site into a file server for DOS or Windows clients. If you want to use command-line utilities like smbclient, smbtar and/or smbspool just need to install the smbclient package. Starting with the Debian Samba packages version 2.2.0-1, the old smbfs utilities for 2.0.x have been removed. There are no wrapper scripts that call a specific smbmount/smbumount depending on the kernel version. If you are using a 2.0.x kernel please upgrade or use the latest Samba 2.0.7 Debian package.

SMS Server Tools for GSM modems The SMS Server Tools make your server into a central SMS gateway. You can send and receive SM using a simple file-based interface. This Software was made for users who send less than 20 000 messages each month. There is an event-handler option that allows you to call your own programs or scripts after sent or received SM. The SMS Server Tools use one or more (max. 32) GSM modems to send and receive SM. You can equip some modems with Vodafone SIM cards and other with Telmi SIM cards (for example), to save money. All SM are sorted in queues by provider. If one modem fails it will be deactivated for one hour before the software retries. The other modems run without any restriction. You can log status information and alarms using the syslog daemon of your operating system.

Show Me The Money is a configurable Perl/Tk stock ticker program smtm, which is a not overly clever acronym for Show Me The Money, is a simple stock ticker application. It creates and automatically updates a window with stock quotes from Yahoo! Finance. When called with one or several stock symbols, it displays these selected stocks, and also records the symbols for later use. When smtm is called without arguments, it reads the symbols tickers from a (default or specified) file. This file can be created explicitly by calling the Save option from the File menu, or implicitly whenever smtm is called with one or more symbols. smtm is fully configurable -- it can display the stock symbol and the full name of the company, the price change, the percentage change, the volume traded, the profit or loss, the value of the holding, the length of the holding period as well as annualised percentage returns. The display can be sort on almost any of the columns. Losers are flagged in red. smtm can be used for North American equities, as well as European and Australian/NZ ones. It should work for other markets supported by Yahoo! Finance. The quotes are delayed, typically 15 minutes for NASDAQ and 20 minutes otherwise, see Yahoo! Finance for details.

Simple Mail Transfer Protocol (RFC 821, TCP/IP) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Key point: Virtually all e-mail exchanged on the Internet is through SMTP. Key point: The most common exploits for SMTP involve spammers trying to relay mail through high-speed mail servers. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
SMTP is the Internet standard for the transferring of electronic mail messages. An SMTP server acts as a central 'post office' for addressing mail to all users within wide area and local area networks. From Faculty-of-Education http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The main protocol used to send electronic mail from server to server on the Internet. SMTP is defined in RFC 821 and modified by many later RFC's. From Matisse http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Simple spam-block with refusal message Smtp-refuser can be configured to reject mail from specific hosts (or that satisfy other tcpd hosts.allow or similar rules), returning a meaningful message including the reason it was bounced and a local phone number. Because spam often has a bad envelope-from, (and because this is more efficient), we bounce it with an error message during the SMTP transaction, rather than send bounce mail later. This SMTP refuser is used along with "tcpd" or (another TCP security daemon) to bounce messages from the IP addresses of known spammers. The advantage of this over just blocking the connection is that the remote SMTP server will not retry, and a legitimate e-mail sender will get a polite message telling them why their mail was blocked and whom to call to get around the blocking. Mail that is not blocked by smtp-refuser is delivered to your standard mail transport agent. Other, more automated solutions such as RBL and ORBS (supported by most of the mail transfer agents), have become available since smtp-refuser was written, but this may still be of interest to you. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Mail proxy for firewalls with anti-spam and anti-relay features Smtpd uses two programs, smtpd which listens for incoming mail and places it in a private queue, and smtpfwdd, which invokes sendmail to deliver messages from the queue. The configuration file for smtpd has powerful features for controlling the acceptance of incoming mail. It is particularly useful for firewall sites, where the policy aspects of which mail should be accepted (in smtpd's configuration file) are clearly separated from the routing and other aspects of the mail configuration (which remain in the sendmail configuration file) It can be used with any mail-transport-agent which can be invoked as sendmail but is intended to integrate with the Debian sendmail package, which recognises when smtpd has been installed. If you are attempting to use it with an MTA other than sendmail then you will need to be prepared to modify the MTA configuration.

ASN.1 to C or C++ or IDL compiler Snacc is short for "Sample Neufeld ASN.1 to C Compiler" and ASN.1 stands for Abstract Syntax Notation One (ITU-T X.208/ISO 8824). Snacc supports a subset of ASN.1 1988. If you need features of ASN.1 1992 or later, snacc is not for you. Given an ASN.1 source file(s) snacc can produce: 1. C routines for BER encoding, decoding, printing and freeing. 2. C++ routines for BER encoding, decoding, and printing. 3. A type table that can be used with C driver routines for BER encoding, decoding, printing and freeing.

A method for keeping track of various hardware devices, such as printers, connected to a network. SNMP can tell network administrators when printers are low on paper or toner, or when a paper jam has occurred. SNMP seems destined to be replaced by die Microsoft at Work standard or the Desktop Management Interface (DMI) standard. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A set of standards for communication with devices connected to a TCP/IP network. Examples of these devices include routers, hubs, and switches. http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The Internet infrastructure is composed of lots of hardware scattered around the place. SNMP is the method that allows someone to "manage" all that equipment. By the word "manage" I mean do things like monitor the amount of traffic flowing through the equipment, trigger when faults occur, change the configuration of equipment remotely, and so forth. Key point: Most equipment comes with default passwords (aka. community strings) of public and private. These allow you to read information from the device (traffic, temperature, voltage, etc.) and re-configure it. Key point: A common technique is to traceroute to a victim's dial-up machine thereby discovering the IP address of the hardware they've dialed into. Then, you can send SNMP commands with the "private" community strings telling the hardware to hang-up on the victim. Also, spammers have used this technique to find the true login name of the user.

It is useful for debugging or analyzing the communications protocol between two devices that would normally be connected directly to each other, e.g. a digital camera and a personal computer. By sitting "in the middle" (after you connect the two devices to serial ports on your Linux machine) snooper is able to capture data traveling in either direction while also passing it unmodified to the other device. It is also possible to operate with a single serial device, using your console and keyboard as the second device. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

In DNS, the SOA record is the "root" record for a domain (or "zone"). Hack: If you control the SOA for a reverse mapping, you can spoof the reverse lookup for an IP address. Let's say that you controlled the DNS server for 132.2.0.192.in-addr.arpa, you can choose to return any domain name you want. This can be used to subvert a number of systems that rely upon reverse lookups, such as older /etc/hosts.equiv files (specifically, the older istrusted() function call).

Social engineering is a form of hacking that targets people's minds rather than their computers. A typical example is sending out snail mail marketing materials with the words "You may already have won" emblazoned across the outside of the letter. As you can see, social engineering is not unique to hackers; it's main practitioners are the marketing departments of corporations. Key point: The classic example is to pretend to be from a company's computer department and call up a user asking for their password. Sophisticated hacks will first try to make the victim uncomfortable (i.e. "We've detected improper use of your account..."), then offer them the opportunity to be very helpful ("I'm sure we can check this out now and not involve your boss."). The technique often works well in reverse: call up the computer support department and tell them you've lost your password. This works especially well in companies that have policies requiring you to change your password -- people forgetting passwords on really old accounts are frequent, so support departments are deluged with such requests, so it's easy to slip one past them. Key point: Know as much about your victim as possible. If you are emulating something, try to find the answers to typical questions you will be asked. Key point: If all else fails, try stupidity. If you are a foreigner, pretend not to speak the language well. Likewise, females have certain advantages in male-dominated cultures. Example: For members-only access, please create an account: Username: Password: Confirm: People often choose the same password for everything. For example, put in your website the prompt shown to the right. A lot of users will use the same username/password for this that they use for websites like Hotmail, Yahoo mail, or Netscape mail. This will therefore sift valid e-mail accounts from people who visit your site. In a similar manner, these passwords might be useful within the companies they work for as well. Key point: Newbies are favorite victims of social-engineering attacks in chat rooms. Hackers go after people who appear to be unsure of themselves online. Key point: Many hackers do not consider social-engineering a "real" attack because it doesn't require extensive technical knowledge in order to pull off. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
An Internet address that combines an IP address (the four-part numerical addrss that uniquely identifies a prticular computer on the Internet) and a port number (which identifies a prticular Internet application, such as File Transfer Protocol [FTP], Gopher, or the World Wide Web [WWW]). See well-known port. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Multi purpose socket tool The socket program is a simple tool for socket based connections. It can be used to create simple daemons (in both standalone and inetd mode), to connect to other daemons or to redirect ports. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
In programming, the "sockets" interface is the most common way that coders use to access the network. Sockets works by creating a "file handle" that when written to, sends data over the network rather than to a file on the hard-disk. Contrast: Other interfaces programmers could use are higher-level abstractions like RPC, or lower-level "raw" interfaces like libnet. Contrast: Sockets originally came from UNIX, but has been ported to other platforms. In particular, the "WinSock" variant for Windows includes both the UNIX-style functions as well as the Windows-style functions. It is possible to write sockets-based programs that compile for both platforms. Key point: The name "sockets" comes from the TCP/IP term "socket". A socket is minimum information necessary needed to communication on the network: the source/destination IP address, the source/destination port, and the transport protocol (UDP or TCP). From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
SOCKet Secure From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
SOCKS is a service that allows internal machines behind a firewall/proxy/gateway access to the Internet. Rather than talking to the target machine, clients communicate with the SOCKS server and ask it to relay data to the target machine out on the Internet. Most web-browsers and FTP clients have SOCKS support built in; SOCKS clients can also be installed on client computers to automatically redirect traffic through the socks gateway. Key point: SOCKS servers are frequently misconfigured allowing both outside and inside people to use them. This means that if a hacker wants to hide where they come from, the hacker scans the Internet for SOCKS proxies, then funnel their data through the proxies they find. When victims trace back to the hacker's IP address, they find the open SOCKS server instead. Key point: Abuse through SOCKS servers has become so common on IRC networks that many of them (dalnet, undernet) have begun scanning clients to see if they are running an open SOCKS proxy. They deny access to anybody coming into the networks through such a proxy. Note that users can still use closed proxies (i.e. those available only to internal users). Key point: SOCKS servers listen by default on TCP port 1080. Real world: Most browsers support SOCKS, which you can see in the "proxy" settings configuration tab. You can download generic SOCKS clients and servers from http://www.socks.nec.com/. SOCKS v5 is specified in RFRC 1928. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

To demonstrate a soft link, try the following: touch myfile; ln -s myfile myfile2; ls -al; cat > myfile; a few lines of text; ^D; cat myfile; cat myfile2; Notice that the ls -al listing has the letter l on the far left next to myfile2, and the usual - next to myfile. This indicates that the file is a soft link (also known as a symbolic link or symlink) to some other file. A symbolic link contains no data of its own, only a reference to another file. It can even contain a reference to a directory. In either case, programs operating on the link will actually see the file or directory it points to. One of the common uses of symbolic links is to make mounted (see Section 19.4) file systems accessible from a different directory. For instance, you may have a large directory that has to be split over several physical disks. For clarity, you can mount the disks as /disk1, /disk2, etc., and then link the various subdirectories in a way that makes efficient use of the space you have. Another example is the linking of /dev/cdrom to, say, /dev/hdc so that programs accessing the device file /dev/cdrom (see Chapter 18) actually access the correct IDE drive.

In network network protocols, source routing is the capability whereby the sender can specify the route a packet should take. Analogy: Somebody asks you how to get to the freeway. You can give them two responses: You tell them to drive a little further on, and there will be signs pointing to the freeway. You tell them just to follow the signs. This is normal routing: you simply hand the packet off to the routers, and let them worry about which direction the packet takes. You tell them to drive up 3 blocks, turn left, then go 2 blocks, then turn right, then go one more block and bear left onto the onramp. This is source routing: you tell the packet every hop it should take through the network. Key point: The hacker can give the packets routes that go around firewalls.

Most spam comes through open SMTP relays. Spam is generally sent through the SMTP mail transfer protocol, though spammers are increasingly making use of web-based e-mail. A big source of spam comes from people who spider websites looking for web-pages that contain e-mail addresses. Since a lot of a web-sites will archive mailing lists and USENET groups, posting to a "private" list will often still expose your e-mail address. The SirCam worm of 2001 spidered the HTML files on the local web-browser cache to forward e-mail, creating a hugely effective manner for discovering new e-mail addresses. Spammers will usually spoof their e-mail address -- you can virtually never reply to the "sender" e-mail address. Netiquette: Use Bcc to send to multiple recipients rather than Cc: or To: fields in order to avoid exposing friends e-mail addresses to potential spammers. Firewalls don't block spam. The @Home cable modem ISP now regularly scans its customers for open USENET relays that spammers often hijack in order to forward spam on newsgroups. Some people are so emotionally against spam that they will will completely shun all access from networks known to be sources of spam. Websites will sometimes scan clients with SNMP or NetBIOS in order to discover their login name. Likewise, some websites sift HTTP fields for usernames (though virtually all web-browsers have disabled this feature). A Rumpelstiltskin attack is where a spammer sends e-mail to all possible names (a@example.com, b@example.com, c@example.com, ...) at a domain. This is similar to a brute-force attack.

vt.,vi.,n. [from "Monty Python's Flying Circus"] 1. To crash a program by overrunning a fixed-size buffer with excessively large input data. See also buffer overflow, overrun screw, smash the stack. 2. To cause a newsgroup to be flooded with irrelevant or inappropriate messages. You can spam a newsgroup with as little as one well- (or ill-) planned message (e.g. asking "What do you think of abortion?" on soc.women). This is often done with cross-posting (e.g. any message which is crossposted to alt.rush-limbaugh and alt.politics.homosexuality will almost inevitably spam both groups). This overlaps with troll behavior; the latter more specific term has become more common. 3. To send many identical or nearly-identical messages separately to a large number of Usenet newsgroups. This is more specifically called `ECP', Excessive Cross-Posting. This is one sure way to infuriate nearly everyone on the Net. See also velveeta and jello. 4. To bombard a newsgroup with multiple copies of a message. This is more specifically called `EMP', Excessive Multi-Posting. 5. To mass-mail unrequested identical or nearly-identical email messages, particularly those containing advertising. Especially used when the mail addresses have been culled from network traffic or databases without the consent of the recipients. Synonyms include UCE, UBE. 6. Any large, annoying, quantity of output. For instance, someone on IRC who walks away from their screen and comes back to find 200 lines of text might say "Oh no, spam". The later definitions have become much more prevalent as the Internet has opened up to non-techies, and to most people senses 3 4 and 5 are now primary. All three behaviors are considered abuse of the net, and are almost universally grounds for termination of the originator's email account or network connection. In these senses the term `spam' has gone mainstream, though without its original sense or folkloric freight - there is apparently a widespread myth among lusers that "spamming" is what happens when you dump cans of Spam into a revolving fan. Hormel, the makers of Spam, have published a surprisingly enlightened position statement on the Internet usage. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
An inappropriate attempt to use a mailing list, or USENET or other networked communications facility as if it was a broadcast medium (which it is not) by sending the same message to a large number of people who didn?t ask for it. The term probably comes from a famous Monty Python skit which featured the word spam repeated over and over. The term may also have come from someone?s low opinion of the food product with the same name, which is generally perceived as a generic content-free waste of resources.

Filter spam from incoming mail This package contains a framework to make it easy to filter spam (i.e. junk email) from your incoming mail. It is intended as a user-controlled filter instead of being attached to the MTA as would otherwise be required. All a user has to do is run "spamfilter" and edit one file to set personal information (email addresses, etc.) to have a fully functional spam filter on their incoming mail. Once installed, the filter is infinitely customizable by the user via the rules of procmail. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

An automated program that reads webpages from a website, then follows the hypertext links to other pages. If the Internet is a "web", then a spider is something that follows the strands of the web. Key point: A website can use the file "robots.txt" to give hints to spiders what they should, or should not, index. A big problem with websites is that spiders are really good at finding webpages, even those that website operators don't care to be exposed. However, users can still find these pages due to hits from search engines. Website operators can therefore "hide" pages by listing them in "robots.txt". However, hackers will therefore read "robots.txt" in order to find webpages that website operators want hidden. Example: Spammers use spiders to sift through web pages looking for e-mail addresses. For example, if you have a link that looks like <A HREF="mailto:spexamp@reckoning.robertgraham.com">me</A> then the spam spider will find the address and funnel spam to you. A partial defense against this is to URL-encode your e-mail address, which hides it from most spam spiders, but works in most browsers. See the page at http://www.robertgraham.com/tools/mailtoencoder.html for an example. Contrast: A spider pulls information inward; a worm pushes itself outward to other systems. A spider is a type of 'bot, rather than infectious malware like viruses, trojans, or worm. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

The word "spoof" generally means the act of forging your identity. More specifically, it means forging the sender's IP address (IP spoofing). Analogy: When you send a letter via normal post (snail mail), you write the recipient's name and address on the envelope. You typically also write the sender's name and address as well, so that if there is an error forwarding you letter (e.g. a stamp falls off), they know who sent the letter and can return it. However, you can easily spoof it. For example, someone I know absolutely had to send a letter, but had no stamps. So he simply put the actual recipient's name as the return address section of the envelope and dropped it into the mail box. The letter was returned to sender, which of course arrived at the intended recipient. Misunderstanding: Most people are interested in spoofing because they think it will allow them to hack a machine in a completely anonymous manner. It doesn't work this way. For example, Mitnick used IP spoofing in order to attack Shimomura's computers, but was caught anyway because spoofing does not truly hide the attacker. The problem is that all responses go back to the sender, so if you've spoofed the sender, you'll never see the responses. Therefore, the spoofing is useless for any normal activity. On the other hand, spoofing can still be useful in situations where seeing the response is not necessary. In the Mitnick instance, two machines trusted each other. Therefore, Mitnick was able to emulate and entire connection between the two machines by "predicting" what all the responses would be. He used this connection to open up something on the victim machine that he could then connect to normally. It was precursor scanning the and the post-spoof connection that Shimomura used to catch Mitnick. Example: A particularly nasty form of a spoofing is TCP sequence number prediction. Theoretically, you cannot spoof any protocol based upon TCP connections. This is because both sides of a TCP connection choose their own Initial Sequence Number (ISN). In theory, this is a completely random number that cannot be guessed. In practice, it can sometimes be easily guessed. Mitnick used this technique when hacking Shimomura. As of the end of 1999, operating systems such as Linux, WinNT, and Win2k have implemented truly random ISNs in order to defeat this type of attack. Example: In terms of volume of traffic, the most common use of spoofing today is smurf and fraggle attacks. These attacks spoofed packets against amplifiers in order to overload the victim's connection. This is done by sending a single packet to a broadcast address with the victim as the source address. All the machines within the broadcast domain then respond back to the victim, overloading the victim's Internet connection. Since smurfing accounts for more than half the traffic on some backbones, ISPs are starting to take spoofing seriously and have started implementing measures within their routers that verify valid source addresses before passing the packets. As a consequence, spoofing will become increasingly more difficult as time goes on. Key point: Most of the discussion of spoofing centers around clients masquerading as somebody else. On the other hand, the reverse problem is equally worrisome: hackers can often spoof servers. For example, I post on my website that there is a serious security fix needed to protect yourself while on the web, and point you to http://www.micrsoft.com and hope that you never notice that the URL is misspelled. You would then go to that site (which would be really my server) and download the patch, which would really be a Trojan Horse that I designed in order to break into your computer. This is why server-side certificates are important: they allow someone to validate that the server isn't bogus. Key point: As the analogy with postal mail shows, many things can be forged, not just the sender's IP address. Most spammers forge their sender's e-mail address in order to avoid all the hate mail they will receive in response. Forging your own sender e-mail address is as simple as reconfiguring your e-mail client -- anybody can do it. (However, there are more secrets to this, which mean you can still be caught by any determined person). Contrast: Blind spoofing describes when you have no knowledge of the responses. Non-blind spoofing is when you are somewhere "in the line of site" as one end of the connection and can sniff some packets. For example, you may spoof a neighbor on the same cable-modem segment. Non-blind spoofing is also used in sniffers like juggernaut to either kill connections or to hijack them. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Simultaneous Peripheral Operations OnLine From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
vi. [from early IBM `Simultaneous Peripheral Operation On-Line', but is widely thought to be a backronym] To send files to some device or program (a `spooler') that queues them up and does something useful with them later. Without qualification, the spooler is the `print spooler' controlling output of jobs to a printer; but the term has been used in connection with other peripherals (especially plotters and graphics devices) and occasionally even for input devices. See also demon. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
To send data to a program that queues up the information for later use (for example, the print spooler). From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
n. Any file to which data is spooled to await the next stage of processing. Especially used in circumstances where spooling the data copes with a mismatch between speeds in two devices or pieces of software. For example, when you send mail under Unix, it's typically copied to a spool file to await a transport demon's attentions. This is borderline techspeak. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Systems services like lpd, innd, sendmail, and uucp create intermediate files in the course of processing each request. These are called spool files and are stored somewhere under the /var/spool/ directory, usually to be processed and then deleted in sequence.

Structured Query Language (ISO 9075, DB, 4GL) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Structured Query Language is a language for manipulating data in relational databases. It has a very simple grammar and is a standard with wide industry support. SQL-based databases have become the core of the classical client/server database concept. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A specialized language for sending queries to databases. Most industrial-strength and many smaller database applications can be addressed using SQL. Each specific application will have its own slightly different version of SQL implementing features unique to that application, but all SQL-capable databases support a common subset of SQL. A example of an SQl statement is: SELECT name,email FROM people_table WHERE contry='uk'. From Matisse http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
In database management systems, an IBM-developed query language widely used in mainframe and minicomputer systems. SQL is gaining acceptance on local area networks (LANs). SQL is an elegant and concise query language with only 30 commands. The four basic Commands (SELECT, UPDATE, DELETE, and INSERT) correspond to the four basic function d data manipulation (data retrieval data modification, data deletion, and data insertion, respectively). SQL queries approximate the structure of an English natural-language query. A data table consisting of columns (corresponding to data fields and rows (corresponding to data records) displays a query's results. See table oriented database management program. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

editor of SQL databases, with 'join' capability sql-editor lets the user edit the contents of the tables of a SQL database through a convenient Gtk graphical interface. The user can also select in the database, using an SQL SELECT query, and browse the results. sql-editor does not create tables, nor it does any other administrative task: you may use mysql-navigator for these. sql-editor is aware of joins (which can be specified by using reg.expressions) THIS EDITOR IS VERY YOUNG AND NOT THROUGHLY TESTED. DO NOT USE IT TO EDIT VALUABLE DATA. (though it should be safe to use it to browse data) sql-editor uses the python module dbGtk, which is included in this package; this module provides classes that automatically parse the structure of SQL tables and prepare Gtk widgets to edit the entries of the tables; these classes rely on a backend module that should be compatible to Python db-api 2.0. dbGtk has been tested on mySql databases, using the module MySQLdb; it may work on PostgreSQL databases, using the module pgSQL From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

See Secure Shell (SSH). From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The Secure Shell, or SSH, provides a way of running command line and graphical applications, and transferring files, over an encrypted connection, all that will be seen is junk. It is both a protocol and a suite of small command line applications, which can be used for various functions. SSH replaces the old Telnet application, and can be used for secure remote administration of machines across the Internet. However, it also has other features. SSH increases the ease of running applications remotely by setting up X permissions automatically. If you can log into a machine, it allows you to run a graphical application on it, unlikt Telnet, which requires users to have an understanding of the X authentication mechanisms that are manipulated through the xauth and xhost commands. SSH also has inbuilt compression, which allows your graphic applications to run much faster over the network. SCP (Secure Copy) and SFTP (Secure FTP) allow transfer of files over the remote link, either via SSH's own command line utilities or graphical tools like Gnome's GFTP. Like Telnet, SSH is cross-platform. You can find SSH server and clients for Linux, Unix and all flavours of Windows, BeOS, PalmOS, Java and embedded Oses used in routers.

Provides a "secure" (i.e. encrypted connection) between the web-browser and the web-server so that the data cannot be sniffed. SSL is used primarily for HTTP, but can also be used for other protocols such as FTP or Telnet. SSL provides three key features: digital-signatures to verify the identity of both the client and server, encryption to prevent the eavesdropping of data, and hashing to protect the integrity of the data. Key point: Web servers have a certificate signed by a trusted certificate authority (CA). This certificate allows the client and the server to generate random keys for the session and to exchange them securely (to defend against man-in-the-middle attacks). The generated random key is used to encrypt the rest of the contents of the connection, usually using RC4. U.S. export controls attempts to limit products used abroad to only 40-bits of key length, which can easily be broken. Key point: In SSL, the server first authenticates itself with the client (a technique that makes it more likely that e-commerce vendors are reputable). Therefore, if you want to set up your own SSL-based web server, you need to get a signed certificate from a CA. Furthermore, if you are outside the U.S., you will find it difficult to find one for 128-bits, though the Chaos Computer Club in Germany manages nicely. Key point: The chief reason SSL isn't used more widely is because it creates a huge performance hit on servers. In particular, the biggest hit comes from handling the public keys in the certificate, though normal encryption/decryption also plays a role. Hardware acceleration for both the public key cryptography and symmetric cryptography are becoming more and more popular. History: SSL was originally developed by Netscape to promote e-commerce. It is also known under the IETF standard name of TLS (Transport Layer Security) and the URL https://. History: In 1996, Netscape's implementation was found to be deeply flawed (i.e. crackable) because of problems in the random number generator. It seeded the generator with the time in seconds and milliseconds as well as the PID (process ID) and PPID (parent process ID). Since these numbers are easy to guess, it gives the random symmetric session key a complexity of roughly 20-bits, which can be easily be brute forced. Subsequent sessions are not re-seeded, which means the discovery of the PRNG seed only needs to be discovered once. Point: SSL allows the encryption algorithm to be negotiated (also known as the "cipher"). Some possible ciphers for SSL are: RC2 with 40-bit keys. RC4 with 40-bit keys. RC4 with 128-bit keys. DES with 40-bit keys. DES with 56-bit keys. Triple-DES with 112/168-bit keys. IDEA with 128-bit keys. Fortezza with 96-bit keys. Point: SSL handshake details: Negotiate cipher Exchange keys Authenticate the server Authenticate the client Authenticate previously exchanged data.

A protocol designed by Netscape Communications to enable encrypted, authenticated communications across the Internet. From Matisse http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
An Internet security standard proposed by Netscape Communications and incorporated into its Netscape Navigator browser and Netscape Commerce Server software. Unlike its chief competition, Secure HyperText Transport Protocol (Secure HTTP), SSL is application-independent it with all Internet tools, not just the World Wide Web (WWW). Applications that use SSL use public key encryption to ensure that, while information is being conveyed through the Internet, no one can intercept that information. Netscape Communications has released the SSL specification to the Internet community as an open standard. Terisa Systems is currently developing a hybrid SSL/Secure H'TTP specification that ensures that any browser with security features can access any secure Web site. See public key cryptography. security The protection of data so unauthorized users cannot examine or copy it. Mainframe computer systems ensured security by keeping the computer and its mass storage media under lock and key, and allowing access only through remote terminals equipped with displays but no disk drives. Although some experts argue that personal computer local area networks (LANs) should be set up the same way, the excessive centralization of mainframe computer systems was one of the main reasons for the development of personal computers. Concern for security shouldn't prevent a manager from distributing computing power-and computing autonomy-to subordinates. Sufficiently advanced data encryption and password-protection schemes can foil even the most skilled and determined hacker. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

n. The set of things a person has to do in the future. One speaks of the next project to be attacked as having risen to the top of the stack. "I'm afraid I've got real work to do, so this'll have to be pushed way down on my stack." "I haven't done it yet because every time I pop my stack something new gets pushed." If you are interrupted several times in the middle of a conversation, "My stack overflowed" means "I forget what we were talking about." The implication is that more items were pushed onto the stack than could be remembered, so the least recent items were lost. The usual physical example of a stack is to be found in a cafeteria: a pile of plates or trays sitting on a spring in a well, so that when you put one on the top they all sink down, and when you take one off the top the rest spring up a bit. See also push and pop. At MIT, PDL used to be a more common synonym for stack in all these contexts, and this may still be true. Everywhere else stack seems to be the preferred term. Knuth ("The Art of Computer Programming", second edition, vol. 1, p. 236) says: Many people who realized the importance of stacks and queues independently have given other names to these structures: stacks have been called push-down lists, reversion storages, cellars, nesting stores, piles, last-in-first-out ("LIFO") lists, and even yo-yo lists! From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A "stack" in an underlying feature of programming languages like C/C++/Java. Normally, most programmers aren't even aware of the stack. It is important to infosec because subverting this hidden detail is one of the primary ways that hackers break into systems.

An extremely aggressive Scheme compiler. stalin is an aggressive self-hosting Scheme compiler, designed to generate resource efficient stand-alone executables with very high computational performance. It is a batch mode compiler like gcc, not an interpreter, and is designed to be used only after your code has stabilized. It places a few limitations on the content of the source code. For example, you may not not LOAD or EVAL new expressions or procedure definitions at runtime, but in exchange, it is able to perform various global analyses which may allow it to transparently map Scheme types to C types and to use native C arithmetic operations on a per-expression basis, whenever such operations are proven safe. Further stalin can often reduce or eliminate run-time type checking and dispatching, and omit garbage collection for data of limited scope or accessability, while omitting unreachable data altogether. stalin also has a foreign procedure interface to both Xlib and OpenGL.

The founder of the GNU project, launched in 1984 to develop the free operating system GNU (an acronym for GNU's Not Unix''), and thereby give computer users the freedom that most of them have lost. GNU is free software: everyone is free to copy it and redistribute it, as well as to make changes either large or small. Richard Stallman is the principal author of the GNU C Compiler, a portable optimizing compiler which was designed to support diverse architectures and multiple languages. The compiler now supports over 30 different architectures and 7 programming languages. Stallman also wrote the GNU symbolic debugger (GDB), GNU Emacs, and various other GNU programs.

The rpc.statd service is a relatively obscure subsystem of the NFS protocol used primarily on UNIX. It is used so that if an NFS server crashes and comes back alive, it can notify clients that this event happened. Many important vulnerabilities have been found in rpc.statd. This means that while it is not so important to system administrators, it is very important to hackers. History: In 1998, Solaris systems across the Internet were broken into via rpc.statd due to a buffer overflow vulnerability (see Solar Sunrise). In 2000, Linux systems throughout the Internet were broken into via a format string vulnerability. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
n. 1. Condition, situation. "What's the state of your latest hack?" "It's winning away." "The system tried to read and write the disk simultaneously and got into a totally wedged state." The standard question "What's your state?" means "What are you doing?" or "What are you about to do?" Typical answers are "about to gronk out", or "hungry". Another standard question is "What's the state of the world?", meaning "What's new?" or "What's going on?". The more terse and humorous way of asking these questions would be "State-p?". Another way of phrasing the first question under sense 1 would be "state-p latest hack?". 2. Information being maintained in non-permanent memory (electronic or human). From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A firewall marketing buzzword, stateful inspection implies that the firewall is remembering stuff from previous packets when making the decision whether or not to forward/block the current packet. Stateful inspection is needed to pass classic FTP as well as newer multimedia protocols (NetMeeting, RealAudio, etc.). Example: Class FTP has a separate control connection and data connection. When you connect to an FTP server and request a file, you tell the server to connect back to you. Since most firewalls allow outgoing connections to servers but block incoming connections, you will be able to connect to the FTP server, but you won't be able to retrieve the desired file. Stateful inspection looks at the outgoing connection and notices that you've requested the incoming connection. The firewall opens up a tiny hole allowing just that inbound connection, thus fixing the entire situation. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

A set of quality standards that make programs more verbose but more readable, reliable, and easily maintained. The goal of structured programming is to avoid spaghetti code caused by overreliance on GOTO statements, a problem often found in BASIC and FORTRAN programs. Structured programming-such as that promoted by C, Pascal Modula-2, and the dBASE software command language - insists that the overall program structure reflect what the program is supposed to do, beginning with the first task and proceeding logically. Indentations help make the logic clear, and the programmer is encouraged to use loops and branch control structures and named procedures rather than GOTO statements.

Small newsfeed from an NNTP server with standard NNTP commands. This package contains software for copying news from an NNTP server to your local machine, and copying replies back up to an NNTP server. The suck/rpost combination allows you to run your own INN/CNEWS site, controlling where you get your news, and where you post outgoing articles. Suck/rpost use only standard NNTP commands that are used by your favorite news reader (like tin, knews, trn) such as POST and ARTICLE. If you can use tin or knews against a NNTP site, than you can use Suck/Rpost and have multiple site feeds. NOTE: Suck will not work with obsolete NNTP servers that can't handle the xhdr command.

Sudo (superuser do) allows a system administrator to give certain users (or groups of users) the ability to run some (or all) commands as root while logging all commands and arguments. Sudo operates on a per-command basis. It is not a replacement for the shell. Features include: the ability to restrict what commands a user may run on aper-host basis, copious logging of each command (providing a clear audit trail of who did what), a configurable timeout of the sudo command, and the ability to use the same configuration file (sudoers) on many different machines.

Set User ID: a file attribute which allows a program to run as a specific user no matter who executes it. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The SUID permission causes a script to run as the user who is the owner of the script, rather than the user who started it.

Software Upgrade Protocol implementation The SUP System is a set of programs developed by Carnegie Mellon University that provide for collections of files to be maintained in identical versions across a number of machines. These programs are: SUP: The "client" program, run by users or system maintainers, which initiates the upgrade activity on a machine requesting the latest version of a collection of files. SUP will normally be run as a daemon, firing up once each night (week, etc.) to upgrade the specified file collections. SUPFILESRV: The "file server" program, a daemon that is run by the system maintainer to service requests for files initiated by client SUP programs. The file server runs on every machine used as a "repository" of distributable versions of files. It runs continuously and listens for network connection requests by individual client processes; for each individual client request, a process is forked to service that request. SUPSCAN: The "file scanner" program, that may optionally be run periodically to speed up execution of the file server. It pre-compiles a list of files on the file system that match the specifications for a given file collection so that the file server need not do this during each upgrade of that collection. The file scanner is normally used daily for very large file collections that are upgraded by many clients each day; it is not so useful for small file collections or for those that are upgraded by only a few client machines per day.

Run higher resolution text modes. This program is designed to greatly improve the normal (EGA-based) textmodes on your Linux machine. It uses an Xconfig-like configuration file to set up better looking textmodes. (=higher resolution, larger font size, higher display refresh...) This is already a big boon on normal 14" displays, and it is an immense difference on larger and better (15" and up) screens. It stems from the idea that it is a real waste of hardware to use EGA textmodes on an SVGA-card, which was designed to do much better than that. This package is mainly of use to people with older hardware that is not adequately supported by the Linux framebuffer drivers. If you abhor 80x25 text modes as much as I do but have a modern cpu and video hardware, then building a kernel with framebuffer support is probably a better option. Some newer video cards are not supported by this package at all (but are supported by the kernel fb drivers) WARNING: This program will not work on non-VGA based systems.

A storage disk partition used to support virtual memory. Data is written to a swap partition when there is not enough main memory to store the data that a system is processing. From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
An important aspect of all operating systems is a feature called "virtual memory". This allows the OS to take unused pieces of memory and write them to disk, then free up the block of memory just written so that another active application can use it. Whenever somebody needs that block again, the operating system will automatically restore it from the disk. Of course, it will then have to free up another block to do so by writing that block to the disk. This technique is generally called "swapping" or "paging". The word "swap" reflects the fact that inactive blocks of memory are being switched with active blocks from the disk. The word "paging" reflects the fact that a common name for a block of memory is "page". The name of the file on the disk that an OS uses for swapping is called the "swapfile" or "pagefile". Key point: A lot of security depends upon the fact that memory is secure: the OS protects applications from reading other application's memory, and that when the computer is turned off, the memory is erased. Therefore, applications can safely store passwords in clear-text in memory. Swapping defeats this, because the memory pages that store the passwords may have been swapped to the disk. Someone with physical access to the machine can turn it off, steal the disk, and run the pagefile through analysis programs in order possibly retrieve passwords.

to move information from a fast-access memory to a slow-access memory (`swap out'), or vice versa (`swap in'). Often refers specifically to the use of disks as `virtual memory'. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
To temporarily move data (programs and/or data files) from random access memory to disk storage (swap out), or back (swap in), to allow more programs and data to be processed than there is physical memory to hold it. Also called Virtual Memory. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
vt. 1. [techspeak] To move information from a fast-access memory to a slow-access memory (`swap out'), or vice versa (`swap in'). Often refers specifically to the use of disks as `virtual memory'. As pieces of data or program are needed, they are swapped into core for processing; when they are no longer needed they may be swapped out again. 2. The jargon use of these terms analogizes people's short-term memories with core. Cramming for an exam might be spoken of as swapping in. If you temporarily forget someone's name, but then remember it, your excuse is that it was swapped out. To `keep something swapped in' means to keep it fresh in your memory: "I reread the TECO manual every few months to keep it swapped in." If someone interrupts you just as you got a good idea, you might say "Wait a moment while I swap this out", implying that a piece of paper is your extra-somatic memory and that if you don't swap the idea out by writing it down it will get overwritten and lost as you talk. Compare page in, page out. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
n. Storage space, especially temporary storage space used during a move or reconfiguration. "I'm just using that corner of the machine room for swap space." From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Where swapped data is temporarily stored on disk. Linux uses a dedicated disk partition for swap space, rather than a specific swap file. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Swap demon for dynamic swap file creation Swapd is a dynamic swapping manager for Linux. It provides the system with as much swap space (virtual memory) as is required at a particular time by dynamically creating swap files. This is more convenient than using fixed swap files and/or partitions because they (a) are unused most of the time and are just taking up disk space; and (b) provide a limited amount of virtual memory. On systems that have constant need for virtual memory it would still be wise to use a swap partition in parallel with dynamic swapping, since swap partitions provide much faster access than swap files.

log file viewer with regexp matching, highlighting, & hooks Swatch is designed to monitor system activity. It reads a configuration file which contains pattern(s) to look for and action(s) to perform when each pattern is found. A typical action is echoing the matched line in a variety of colours and formats including reverse video, bold, underline, and normal, which swatch knows how to do internally. Other actions include sending mail or executing an arbitrary program on the line. Swatch is written in Perl and uses Perl regular expressions for line matching. This Debian version of swatch includes two directives not yet found in the "official" swatch -- "PERLCODE" and "threshold".

The part of an object table that gives the value of each symbol (usually as a section name and an offset) is called the symbol table. Executables may also have a symbol table, with this one giving the final values of the symbols. Debuggers use the symbol table to present addresses to the user in a symbolic, rather than a numeric form. It is possible to strip the symbol table from executables resulting in a smaller sized executable but this prevents meaningful debugging.

An alias or shortcut to a program or file. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A special filetype, which is a small pointer, file allowing multiple names for the same file. Unlilke hard links, symbolic links can be made for directories and can be made across filesystems. Commands that access the file being pointed to are said to follow the symbolic link. Commands that access the link itself do not follow the symbolic link. From Rute-Users-Guide http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
On UNIX, a symbolic link is where a file in one directory acts as a pointer to a file in another directory. For example, you could create a link so that all accesses to the file /tmp/foo really act upon the file /etc/passwd. This feature can often be exploited. While a non-root user does not have permission to write to administrative files like /etc/passwd, they can certainly create links to them in the /tmp directory or their local directory. SUID can then be exploited whereby they believe they are acting upon a user file, which which are instead acting upon the original administrative file. This is the leading way that local users can escalate their privileges on a system. Example: finger A user could link their .plan file to any other file on the system. A finger daemon running with root privileges would then follow the link to that file and read it upon execution of a finger lookup. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
scan/change symbolic links Symlinks scans directories for symbolic links and lists them on stdout. Each link is prefixed with a classification of relative, absolute, dangling, messy, lengthy or other_fs.

The first packet sent across a TCP connection is known as a "SYN" or "synchronize" packet. For example, when you contact http://www.robertgraham.com, the first packet your systems out will be a SYN packet to the HTTP port 80 on www.robertgraham.com. Your browser is telling the web server that it wants to connect. Key point: Most packet-filtering firewalls work by blocking the SYN packets. This stops connections from being initiated. You can still scan behind these firewalls using ACK or FIN packets, but you will not be able to connect to any of those machines. See also: SYN flood, three-way-handshake, TCP From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A SYN flood is a type of DoS attack. A SYN packet notifies a server of a new connection. The server then allocates some memory in order to handle the incoming connection, sends back an acknowledgement, then waits for the client to complete the connection and start sending data. By spoofing large numbers of SYN requests, an attacker can fill up memory on the server, which will sit their waiting for more data that never will arrive. Once memory has filled up, the server will be unable to accept connections from legitimate clients. This effectively disables the server. Key point: SYN floods exploit a flaw in the core of the TCP/IP technology itself. There is no complete defense against this attack. There are, however, partial defenses. Servers can be configured to reserve more memory and decrease the amount of time they wait for connections to complete. Likewise, routers and firewalls can filter out some of the spoofed SYN packets. Finally, there are techniques (such as "SYN cookies") that can play tricks with the protocol in order to help distinguish good SYNs from bad ones.

System-V like init. Init is the first program to run after your system is booted, and continues to run as process number 1 until your system halts. Init's job is to start other programs that are essential to the operation of your system. All processes are descended from init. For more information, see the manual page init(8).

The SysVinit package contains a group of processes that control the very basic functions of your system. SysVinit includes the init program, the first program started by the Linux kernel when the system boots. Init then controls the startup, running and shutdown of all other programs.
