/T/ 1. [from LISP terminology for 'true'] Yes. Used in reply to a question (particularly one asked using The -P convention). In LISP, the constant T means 'true', among other things. Some Lisp hackers use 'T' and 'NIL' instead of 'Yes' and 'No' almost reflexively. This sometimes causes misunderstandings. When a waiter or flight attendant asks whether a hacker wants coffee, he may absently respond 'T', meaning that he wants coffee; but of course he will be brought a cup of tea instead. Fortunately, most hackers (particularly those who frequent Chinese restaurants) like tea at least as well as coffee -- so it is not that big a problem. 2. See time T (also since time T equals minus infinity). 3. [techspeak] In transaction-processing circles, an abbreviation for the noun 'transaction'. 4. [Purdue] Alternate spelling of tee. 5. A dialect of LISP developed at Yale. (There is an intended allusion to NIL, "New Implementation of Lisp", another dialect of Lisp developed for the VAX) [7]

A leased-line connection capable of carrying data at 1,544,000 bits-per-second. At maximum theoretical capacity, a T-1 line could move a megabyte in less than 10 seconds. That is still not fast enough for full-screen, full-motion video, for which you need at least 10,000,000 bits-per-second. T-1 lines are commonly used to connect large LANs to the Internet. [5]

A leased-line connection capable of carrying data at 44,736,000 bits-per-second. This is more than enough to do full-screen, full-motion video. [5]

A branch of Semi-gnus (Gnus for SEMI) variants. Semi-gnus is a replacement of Gnus with gnus-mime for SEMI. It has all features of Gnus and gnus-mime, so there are no need to install Gnus to use it, and you must not use gnus-mime for SEMI. It requires SEMI package, so please get and install SEMI package before to install it. Use T-gnus in offline(Unplugged) status using gnus-offline. T-gnus have also features that have Semi-gnus MainTrunk. Enable to get Multiple Pop server in POP and APOP using pop3-fma.el (pop3 For Multi Account). By Tatsuya Ichikawa <t-ichi@po.shiojiri.ne.jp>. T-gnus is one of Semi-gnus variants. Now, "Semi-gnus" is generic name of Gnus for SEMI. [3]

display filter for RFC822 messages This program is a filter which shall improve the readability for messages (email and posts) by *hiding* some annoying parts, e.g. mailing list footers, signatures and TOFU as well as squeezing sequences of blank lines or punctuation. TOFU is an acronym that stands for "Text oben, Fullquote unten" (german language) which means the style of sadly so many people that just leave all the quotes in a reply and add some own lines above. This acronym is what gave the script it's name - TOFU Protection. It currently offers hints how to include it within mutt. It should be possible to do similars with other mailers that allow to have a message run through a program before it's displayed. If you have such an mailer I'd be interested if you could let me know of your setup. [3]

Type 1 font rasterizer library - user binaries T1lib is an enhanced rasterizer for Type 1 fonts. T1lib is based on the X11R5 font rasterizer code, but operates independently of X11. It includes many enhancements, including underlining, antialiasing, user-defined slant and extension factors, and rotation. This package contains the programs "xglyph" and "type1afm", included in the upstream T1lib distribution. It also contains the "t1libconfig" script used to configure t1lib. [3]

T1lib is a library for generating character and string-glyphs from Adobe Type 1 fonts under UNIX. T1lib uses most of the code of the X11 rasterizer donated by IBM to the X11-project. But some disadvantages of the rasterizer being included in X11 have been eliminated. T1lib also includes a support for antialiasing. [4]

Type 1 font rasterizer library - runtime T1lib is an enhanced rasterizer for Type 1 fonts. T1lib is based on the X11R5 font rasterizer code, but operates independently of X11.

This package contains the shared libraries needed to run programs using T1lib. [3]

A tool to help xdvi use all your t1 fonts [34]

A collection of simple Type 1 font manipulation programs. t1utils is a collection of simple type-1 font manipulation programs. Together, they allow you to convert between PFA (ASCII) and PFB (binary) formats; disassemble PFA or PFB files into human-readable form; and reassemble the human-readable files into PFA or PFB format files. You can also extract font resources from a Macintosh font file (ATM/Laserwriter), or create a Macintosh Type 1 font file from a PFA or PFB font. There are currently six programs: t1ascii Converts PFB files to PFA format. t1binary Converts PFA files to PFB format. t1disasm Disassembles a Type 1 font (PFA or PFB format) into a raw, human-readable text form for subsequent hand editing, tweaking, hint fixing, etcetera... t1asm Assembles a Type 1 font into PFA or PFB format from the human-readable form produced by t1disasm. t1unmac Extracts POST resources from a Macintosh Type 1 font file (ATM/Laserwriter) into PFA or PFB format for use outside the Macintosh environment. The Macintosh file should be stored in MacBinary, AppleSingle, AppleDouble, or BinHex format, or as a raw resource fork. Note that t1unmac does not have to run on a Macintosh, but makes Macintosh Type 1 fonts available for use on Unix machines and PCs. t1mac Creates a Macintosh Type 1 file from a PFA- or PFB-format Type 1 font. Writes the Macintosh file in MacBinary, AppleSingle, AppleDouble, or BinHex format, or as a raw resource fork. WARNING: This tool will not suffice to allow you to use the new font on a Macintosh, as Macintoshes cannot read raw Type 1 fonts. You will need to create a font suitcase containing bitmap fonts. If you do not already have such a suitcase for the font, T1utils will not help you create one. This version of the t1utils programs has been maintained by Eddie Kohler <eddietwo@lcs.mit.edu> since version 1.5, based on the original code by I. Lee Hetherington. As such, it is a complete replacement for the t1utils Debian package, which is based on version 1.2 of I. Lee Hetherington's code. [3]

The t1utils package is a set of programs for manipulating PostScript Type 1 fonts. It contains programs to change between binary PFB format (for storage), ASCII PFA format (for printing), a human-readable andeditable ASCII format, and Macintosh resource forks. [4]

A common vulnerability that hackers use to break into systems is the lack of proper input validation. The problem is that programmers expect users to enter in "proper" input, but fail to check for the case of hostile users carefully crafting input designed to compromise the system. The problems with input validation is that the part of the system that receives the input does not know enough to validate it properly. On the other hand, every single component in the system cannot thoroughly validate input. The concept of "taint" is to mark certain inputs as having been entered by the user. Only a thorough desconstruction/reconstruction of the data removes the taint. Some programming languages, like PERL, automate this tracking. Others, like C, requires manual tracking. Example: Version 4 of PERL has a special alternative interpretter called tainperl that tracks tainted input. Version 5 of PERL has the option "-T" that tracks taint. See also: metacharacter [96]

Talk to another user. Talk is a visual communication program which copies lines from your terminal to that of another user. In order to talk locally, you will need to install the talkd package. [3]

The talk package provides client and daemon programs for the Internet talk protocol, which allows you to chat with other users on different systems. Talk is a communication program which copies lines from one terminal to the terminal of another user. [93]

n. A feature supported by Unix, ITS, and some other OSes that allows two or more logged-in users to set up a real-time on-line conversation. It combines the immediacy of talking with all the precision (and verbosity) that written language entails. It is difficult to communicate inflection, though conventions have arisen for some of these (see the section on writing style in the Prependices for details). Talk mode has a special set of jargon words, used to save typing, which are not used orally. Some of these are identical to (and probably derived from) Morse-code jargon used by ham-radio amateurs since the 1920s. AFAIAC as far as I am concerned AFAIK as far as I know BCNU be seeing you BTW by the way BYE? are you ready to unlink? (this is the standard way to end a talk-mode conversation; the other person types BYE to confirm, or else continues the conversation) CUL see you later ENQ? are you busy? (expects ACK or NAK in return) FOO? are you there? (often used on unexpected links, meaning also "Sorry if I butted in ..." (linker) or "What's up?" (linkee)) FWIW for what it's worth FYI for your information FYA for your amusement GA go ahead (used when two people have tried to type simultaneously; this cedes the right to type to the other) GRMBL grumble (expresses disquiet or disagreement) HELLOP hello? (an instance of the '-P' convention) IIRC if I recall correctly JAM just a minute (equivalent to SEC....) MIN same as JAM NIL no (see NIL) NP no problem O over to you OO over and out / another form of "over to you" (from x/y as "x over y") \ lambda (used in discussing LISPy things) OBTW oh, by the way OTOH on the other hand R U THERE? are you there? SEC wait a second (sometimes written SEC...) SYN Are you busy? (expects ACK, SYN|ACK, or RST in return; this is modeled on the TCP/IP handshake sequence) T yes (see the main entry for T) TNX thanks TNX 1.0E6 thanks a million (humorous) TNXE6 another form of "thanks a million" WRT with regard to, or with respect to. WTF the universal interrogative particle; WTF knows what it means? WTH what the hell? <double newline> When the typing party has finished, he/she types two newlines to signal that he/she is done; this leaves a blank line between 'speeches' in the conversation, making it easier to reread the preceding text. <name>: When three or more terminals are linked, it is conventional for each typist to prepend his/her login name or handle and a colon (or a hyphen) to each line to indicate who is typing (some conferencing facilities do this automatically). The login name is often shortened to a unique prefix (possibly a single letter) during a very long conversation. /\/\/\ A giggle or chuckle. On a MUD, this usually means 'earthquake fault'. Most of the above sub-jargon is used at both Stanford and MIT. Several of these expressions are also common in email, esp. FYI, FYA, BTW, BCNU, WTF, and CUL. A few other abbreviations have been reported from commercial networks, such as GEnie and CompuServe, where on-line 'live' chat including more than two people is common and usually involves a more 'social' context, notably the following: <g> grin <gd&r> grinning, ducking, and running BBL be back later BRB be right back HHOJ ha ha only joking HHOK ha ha only kidding HHOS ha ha only serious IMHO in my humble opinion (see IMHO) LOL laughing out loud NHOH Never Heard of Him/Her (often used in initgame) ROTF rolling on the floor ROTFL rolling on the floor laughing AFK away from keyboard b4 before CU l8tr see you later MORF male or female? TTFN ta-ta for now TTYL talk to you later OIC oh, I see rehi hello again Most of these are not used at universities or in the Unix world, though ROTF and TTFN have gained some currency there and IMHO is common; conversely, most of the people who know these are unfamiliar with FOO?, BCNU, HELLOP, NIL, and T. The MUD community uses a mixture of Usenet/Internet emoticons, a few of the more natural of the old-style talk-mode abbrevs, and some of the 'social' list above; specifically, MUD respondents report use of BBL, BRB, LOL, b4, BTW, WTF, TTFN, and WTH. The use of 'rehi' is also common; in fact, mudders are fond of re- compounds and will frequently 'rehug' or 'rebonk' (see bonk/oif) people. The word 're' by itself is taken as 'regreet'. In general, though, MUDders express a preference for typing things out in full rather than using abbreviations; this may be due to the relative youth of the MUD cultures, which tend to include many touch typists and to assume high-speed links. The following uses specific to MUDs are reported: CU l8er see you later (mutant of CU l8tr) FOAD f*** off and die (use of this is generally OTT) OTT over the top (excessive, uncalled for) ppl abbrev for "people" THX thanks (mutant of TNX; clearly this comes in batches of 1138 (the Lucasian K)). UOK? are you OK? Some B1FFisms (notably the variant spelling d00d) appear to be passing into wider use among some subgroups of MUDders. One final note on talk mode style: neophytes, when in talk mode, often seem to think they must produce letter-perfect prose because they are typing rather than speaking. This is not the best approach. It can be very frustrating to wait while your partner pauses to think of a word, or repeatedly makes the same spelling error and backs up to fix it. It is usually best just to leave typographical errors behind and plunge forward, unless severe confusion may result; in that case it is often fastest just to type "xxx" and start over from before the mistake.

Full-screen system backup utility. Taper is a tape backup and restore program that provides a friendly user interface to allow backup/restore to a tape drive. Alternatively, files can be backed up to hard disk files. Selecting files for backup and restore is very similar to the Mouseless Commander interface and allows easy traversal of directories. Recursively selected directories are supported. Incremental backup and automatic most recent restore are defaults settings. SCSI, ftape, zftape, ide tape drives, and removable drives are supported. [3]

Telephony Application Program Interface (Intel, MS, WOSA, CTI) [95]

A tool for real time audio delay and feedback effects. Tapiir is a simple and flexible audio effects processor, inspired on the classical magnetic tape delay systems used since the early days of electro-acoustic music composition. It provides a graphical user interface consisting of six delay lines, or "taps", which can introduce an almost arbitrarily big or small delay to their inputs and can be feed back to each other. A wide set of effects can be easily achieved by properly configuring and connecting the delay lines: complex echo patterns, resonances, filtering, etc. Delays, interconnections and gains can all be controlled in real time. Tapiir requires the ALSA sound driver. [3]

A program used to create a single file archive from several files, often used to distribute programs for Unix. The Unix command has many options. [42]

An archiver that is used to combine many files and directories in single archive file. The name comes from 'Tape ARchive', since the utility was created to make tape backups of Unix systems. [32]

GNU tar Tar is a program for packaging a set of files as a single archive in tar format. The function it performs is conceptually similar to cpio, and to things like pkzip in the DOS world. It is heavily used by the Debian package management system, and is useful for performing system backups and exchanging sets of files with others. [3]

Tape ARchiver (Unix) [95]

The GNU tar program saves many files together into one archive and can restore individual files (or all of the files) from the archive. Tar can also be used to add supplemental files to an archive and to update or list files in the archive. Tar includes multivolume support, automatic archive compression/decompression, the ability to perform remote archives and the ability to perform incremental and full backups. If you want to use Tar for remote backups, you'll also need to install the rmt package. You should install the tar package, because you'll find its compression and decompression utilities essential for working with files. [4]

A file packaging tool included with UNIX/Linux for the purpose of assembling a collection of files into one combined file for easier archiving. It was originally designed for tape backup, but today can be used with other storage media. When run by itself, it produces files with a .tar extension. When combined with Gzip, for data compression, the resulting file extensions may be .tgz, .tar.gz or .tar.Z. [8]

vi. [from Unix tar(1)] To create a transportable archive from a group of files by first sticking them together with tar(1) (the Tape ARchiver) and then compressing the result (see compress). The latter action is dubbed 'feathering' partly for euphony and (if only for contrived effect) by analogy to what you do with an airplane propeller to decrease wind resistance, or with an oar to reduce water resistance; smaller files, after all, slip through comm links more easily. Compare the more common tarball. [7]

A file created by the Tar utility, containing one or more other archived and, optionally, compressed files. [8]

A file created with the "tar" command containing a collection of other files. [32]

n. [very common; prob. based on the "tar baby" in the Uncle Remus folk tales] An archive, created with the Unix tar(1) utility, containing myriad related files. "Here, I'll just ftp you a tarball of the whole project." Tarballs have been the standard way to ship around source-code distributions since the mid-1980s; in retrospect it seems odd that this term did not enter common usage until the late 1990s. [7]

Tarball filter Tarcust is a tool designed to help developers rolling tarballs out of their programs. It acts as a filter on tar archives, any change on file attributes (like its name, uid, gid, etc) can be performed, and files can be removed but not added to archive. [3]

Tcl is a simple scripting language designed to be embedded into other applications. Tcl is designed to be used with Tk, a widget set, which is provided in the tk package. This package also includes tclsh, a simple example of a Tcl application. If you're installing the tcl package and you want to use Tcl for development, you should also install the tk and tclx packages. [4]

Tool Command Language [95]

Tcl (generally pronounced "tickle") is a command language designed and first implemented by John Ousterhout. Tcl is an extensible, interpreted, programming language, which has been ported to a wide range of machines and operating systems. Tk (pronounced "Tee-kay") is an X-windows toolkit for Tcl. It is generally claimed that Tcl/Tk implementations of software require approximately 10 times less code than the corresponding software in C. [32]

Tcl is a scripting language. It is an easy to learn interpreted language that uses a typeless approach to achieve a higher level of programming and a rapid application development. The Tk toolkit is a programming environment for creating graphical user interf aces (GUI) under X Window System. Their capabilities include the possibility to extend and embed in other application, rapid development and ease of use. Toge ther, Tcl and Tk provide many benefits both to application developer and user. Tk-ba sed interfaces tend to be much more customizable and dynamic than those built with one of the C or C++ based toolkits. Tk implements the Motif look and feel. A great number of interesting X applications are implemented entirely in Tk, with no new application-specific commands at all. [10]

Tcl interface to libcurl This module provides the same functionality as libcurl provides to C/C++ programs, please refer to the documentation of libcurl. [3]

A lexical analyzer generator for Tcl tcLex is a lexer (lexical analyzer) generator extension to Tcl. It is inspired by Unix and GNU lex and flex, which are "tools for generating programs that perform pattern-matching on text". tcLex is very similar to these programs, except it uses Tcl philosophy and syntax, whereas the others use their own syntax and are used in conjunction with the C language. People used to lex or flex should then feel familiar with tcLex. tcLex is a small extension (the Windows compiled version is about 20kb, and the source is about 150kb), because it extensively uses the Tcl library. However, the current doesn't use Tcl's regexp code anymore but a patched version is now included in tcLex, which makes it slightly bigger (by a few KB). tcLex should work with Tcl 8.0 and later. tcLex will NEVER work with earlier versions, because it uses Tcl 8.0's "object" system for performance. The most interesting features are: * cross-platform support, thanks to Tcl. Though it has been developed on Windows and tested on Windows and Unix only, it should work on other platforms as long as Tcl exists on these platforms. Supported Tcl platforms are Windows 95/NT, Unix (Linux, Solaris...) and Macintosh. Other platforms are VMS, OS/2, NeXTStep, Amiga... * unlike lex and flex, which only generate static lexers written in C and intended to be compiled, tcLex dynamically generates Tcl commands that can be used like other C commands or Tcl procedures from within Tcl scripts or C programs. * it uses Tcl regular expressions. That means you don't have to learn another regexp language. * it works with Tcl namespaces * the generated lexer commands can be used in one pass or incrementally, because they maintain state information. That way, several instances of the same lexer (eg a HTML parser) can run at the same time in distinct call frames and maintain distinct states (local variables...). Lexer need not be specially designed in order to be used incrementally, the same lexer can transparently be used in one pass or incrementally. This feature is especially useful when processing text from a file or an Internet socket (Web pages for example), when data is not necessarily available at the beginning of the processing. [3]

Tcl interface to expat XML parser. This package provides a Tcl interface to James Clark's expat library. It creates a Tcl package, called "expat", which defines a single new Tcl command "expat". [3]

TclX provides additional interfaces to the operating system, and adds many new programming constructs, text manipulation tools, and debugging tools. The tclx8.3 package doesn't include programs and libraries depending on Tk. You need the tkx8.3 package for these. [3]

Transmission Control Protocol (ARPANET) [95]

Transmission Control Protocol--the big kahoona of the Internet Protocols. TCP takes the information to be generated by an application and passes it to the IP (Internet Protocol) to be transmitted. IP is responsible for getting a packet of information from one host to another, while TCP is responsible for making sure messages get from one host to another and that the messages are understood. [44]

Transmission Control Protocol. The chief transport protocol for TCP/IP. Key point: TCP is "connection oriented". This means the three-way handshake must be completed before any data can be sent across the connection. This makes IP address spoofing impossible without sequence number prediction. Key point: TCP creates a virtual "byte stream" for applications. Therefore, applications that send/receive data must create their own boundaries, such as length encoding the data, or send text data a line at a time. However, in practice, applications do indeed send data aligned on packet boundaries. Most network-based intrusion detection systems depend upon these boundaries in order to work correctly. Therefore, they can easily be evaded by custom written scripts that misalign the data. The applications don't see any difference, but the NIDS see something completely different go across the wire that no longer matches their signatures. Contrast: There are two transport protocols: TCP and UDP. Whereas TCP is connection-oriented, UDP is connectionless, meaning UDP-based applications are easily spoofed. [96]

When trying to spoof a TCP connection, the intruder is faced with the difficulty that he will never see the response to a SYN packet.. This is a problem because the victim sends back information to the spoofed address that is needed to carry on the conversation, namely the sequence number being used by the victim. Luckily (for hackers), most systems choose sequence numbers in a predictable way. History: Kevin Mitnick was caught doing TCP sequence number prediction against Tsutmu Shimomura. The reason Shimomura was able to catch Mitnick is because in order to predict the next sequence number, you must first grab the previous number using a non-spoofed connection. History: One of the first to point out this security problem was Robert T. Morris in a 1985 paper entitled A Weakness in the 4.2BSD Unix TCP/IP Software. [96]

(often written as TCP/IP because it works together with IP). TCP is a protocol which ensures that data transmitted is received in the intended order and free of errors. The reason for this is that when computer data is transmitted over the Internet it is broken up into small 'packets' which may travel over different routes. [2]

Transmission Control Protocol/Internet Protocol. It is the data communication protocol most often used on Linux machines. [Transmission Control Protocol/Internet Protocol] The wide-area-networking protocol that makes the Internet work, and the only one most hackers can speak the name of without laughing or retching. Unlike such allegedly 'standard' competitors such as X.25, DECnet, and the ISO 7-layer stack, TCP/IP evolved primarily by actually being used, rather than being handed down from on high by a vendor or a heavily-politicized standards committee. [32]

Transmission Control Protocol/Internet Protocol. It is the data communication protocol most often used on Unix machines. [19]

Almost all of the services provided through inetd are invoked through tcp-wrappers by way of the tcp-wrappers daemon, tcpd. The tcp-wrappers mechanism provides access control list restrictions and logging for all service requests to the service it wraps. It may be used for either TCP or TCP services as long as the services are invoked through a central daemon process such as inetd. These programs log the client host name of incoming telnet, ftp, rsh, rlogin, finger etc.... requests. Security options are access control per host, domain and/or service; detection of host name spoofing or host address spoofing; booby traps to implement an early-warning system. [64]

/T'C-P I'P/ n. 1. [Transmission Control Protocol/Internet Protocol] The wide-area-networking protocol that makes the Internet work, and the only one most hackers can speak the name of without laughing or retching. Unlike such allegedly 'standard' competitors such as X.25, DECnet, and the ISO 7-layer stack, TCP/IP evolved primarily by actually being used, rather than being handed down from on high by a vendor or a heavily-politicized standards committee. Consequently, it (a) works, (b) actually promotes cheap cross-platform connectivity, and (c) annoys the hell out of corporate and governmental empire-builders everywhere. Hackers value all three of these properties. See creationism. 2. [Amateur Packet Radio] Formerly expanded as "The Crap Phil Is Pushing". The reference is to Phil Karn, KA9Q, and the context was an ongoing technical/political war between the majority of sites still running AX.25 and the TCP/IP relays. TCP/IP won. [7]

see transmission control protocol on top internet protocol (TCP/IP). [94]

Describes the protocols used on the Internet. The term evolved from the fact that these were the two most important protocols for engineers. If you talk about how to get data across the network from machine to machine, then you talk about IP packets. If you are interested in the abstract communication between applications, then you talk about TCP connections. If talk about generic transport of data encompassing both concepts (machine and application), then you naturally talk about both TCP and IP, or simply TCP/IP. [96]

This is the suiteof protocols that defines the Internet. Originally designed for the UNIX operating system, TCP/IP software is now included with every major kind of computer operating system. To be truly on the Internet, your computer must have TCP/IP software. [5]

tcp wrapper configuration checker [34]

tcp wrapper oracle [34]

A powerful tool for network monitoring and data acquisition This program allows you to dump the traffic on a network. tcpdump is able to examine IPv4, ICMPv4, IPv6, ICMPv6, UDP, TCP, SNMP, AFS BGP, RIP, PIM, DVMRP, IGMP, SMB, OSPF, NFS and many other packet types. It can be used to print out the headers of packets on a network interface, filter packets that match a certain expression. You can use this tool to track down network problems, to detect "ping attacks" or to monitor network activities. More information is at <URL: http://www.tcpdump.org/> [3]

Tcpdump is a command-line tool for monitoring network traffic. Tcpdump can capture and display the packet headers on a particular network interface or on all interfaces. Tcpdump can display all of the packet headers, or just the ones that match particular criteria. [93]

TCP flow recorder tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis or debugging. A program like 'tcpdump' shows a summary of packets seen on the wire, but usually doesn't store the data that's actually being transmitted. In contrast, tcpflow reconstructs the actual data streams and stores each flow in a separate file for later analysis. tcpflow understands sequence numbers and will correctly reconstruct data streams regardless of retransmissions or out-of-order delivery. However, it currently does not understand IP fragments; flows containing IP fragments will not be recorded properly. tcpflow is based on the LBL Packet Capture Library and therefore supports the same rich filtering expressions that programs like 'tcpdump' support. tcpflow can also rebuild flows from data captured with 'tcpdump -w'. [3]

TCP extensions for Long Delay Paths (RFC 1072, TCP) [95]

A dialout/masquerading monitoring package. TCPQuota monitors and debit users depending on there online time (dialout). The program is made for those who have a local network with a server that also functions as a Internet gateway (among other things). The server runs diald, for example, which does the actual dial-on-demand, and this package which debit each user, whether from the server or from a masqueraded host (program includes masquerade code). All a user from inside the gateway/firewall have to do is run the command 'openhost', and the hostname and username is masqueraded and debited according to the time they spend calling out. [3]

Tool to replay saved tcpdump files at arbitrary speeds Tcpreplay is aimed at testing the performance of a NIDS by replaying real background network traffic in which to hide attacks. Tcpreplay allows you to control the speed at which the traffic is replayed, and can replay arbitrary tcpdump traces. Unlike programmatically-generated artificial traffic which doesn't exercise the application/protocol inspection that a NIDS performs, and doesn't reproduce the real-world anomalies that appear on production networks (asymmetric routes, traffic bursts/lulls, fragmentation, retransmissions, etc.), tcpreplay allows for exact replication of real traffic seen on real networks. [3]

extract pieces of and/or glue together tcpdump files Tcpslice is a program for extracting portions of packet-trace files generated using tcpdump(l)'s -w flag. It can also be used to glue together several such files. [3]

Incoming and Outgoing TCP/IP connections logger. tcpspy is an administrator's tool that logs information about incoming and outgoing TCP/IP connections. It's written in C and uses no libpcap functions, unlike tcpdump. Connections are selected for logging with rules, similarly to the filter expressions accepted by tcpdump. The following information is logged: username, local address and port, remote address and port, and, optionally, the executable filename. At present, only the IPv4 protocol is supported. [3]

network interface statistics reporting tool tcpstat reports certain network interface statistics much like vmstat does for system statistics. tcpstat gets its information by either monitoring a specific interface, or by reading previously saved tcpdump data from a file. [3]

A traceroute implementation using TCP packets The more traditional traceroute(8) sends out either UDP or ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination. The problem is that with the widespread use of firewalls on the modern Internet, many of the packets that traceroute(8) sends out end up being filtered, making it impossible to completely trace the path to the destination. However, in many cases, these firewalls will permit inbound TCP packets to specific ports that hosts sitting behind the firewall are listening for connections on. By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common firewall filters. [3]

Utilities for TCP programming in shell-scripts This is a collection of programs to facilitate TCP programming in shell-scripts. There is also a small library which makes it somewhat easier to create TCP/IP sockets. The programs included in this release are: mini-inetd - small TCP/IP connection dispatcher tcpbug - TCP/IP connection bugging device tcpconnect - general TCP/IP client tcplisten - general TCP/IP server getpeername - get name of connected TCP/IP peer [3]

acts as an intermediary between inetd and the server program to be run, providing a filtering "wrapper" that allows connections to be allowed or denied based on the host or network address. [32]

The tcp_wrappers package provides small daemon programs that canmonitor and filter incoming requests for systat, finger, FTP, telnet, rlogin, rsh, exec, tftp, talk, and other network services. Install the tcp_wrappers program if you need a security tool for filtering incoming network services requests. [93]

Character set translator. tcs translates character sets from one encoding to another. Supported encodings include utf (ISO utf-8), ascii, ISO 8859-[123456789], koi8, jis-kanji, ujis, ms-kanji, jis, gb, big5, unicode, tis, msdos, and atari. [3]

Transmission Convergence Sublayer (ATM) [95]

Trusted Computer System Evaluation Criteria (Orange Book, NCSC) [95]

A formal and academic specification of infosec created by the United States Department of Defense in the early 1980s. Point: TCSEC is divided in four parts: A, B, C, and D, where 'A' describes systems with the highest security and 'D' describes untrusted/untrustworthy systems. Each of these is further subdivided into "classes". Microsoft received "C2" certification for Windows NT. This mean the government certified the system as to conforming to class 2 of division C. Contrast: TCSEC is designed around the concept of trusted employees accessing local systems. It was not designed for todays open Internet access. Hackers do not approach security from the TCSEC point of view. TCSEC doesn't deal with types of threats hackers pose. What this means is that the TCSEC approach is irrelevent when trying to defend your e-commerce site against hackers. However, it is extremely useful in protecting internal systems from internal people. Remember that the biggest threat is from your own internal employees, and that most cybercriminals were convicted for having abused trust placed in them. [96]
