T

T

/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) From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

T-1

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. From Matisse http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

T-3

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. From Matisse http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

t-code

Yet another Japanese input method T-Code is Japanese input method that doesn't use Kana-to-Kanji conversion. You can input Kanji characters directly in the same way of inputting Hiragana. This packages also provides TUT-Code input method (the alternative of T-Code). From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

t-gnus

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

t-prot

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

t1lib-bin

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

t1lib1

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. From Mandrake 9.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

t1lib1

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.

t1utils

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

taint

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.

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. From Redhat 8.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

talk mode

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.

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tar

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.

TAR

Tape ARchiver (Unix) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tar

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. From Mandrake 9.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Tar (Tape ARchive)

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. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tar and feather

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. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

TCL

Tool Command Language From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Tcl/Tk

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. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Tcl/Tk

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. From Tcl/Tk HOWTO http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tclcurl

Tcl interface to libcurl This module provides the same functionality as libcurl provides to C/C++ programs, please refer to the documentation of libcurl. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tclex

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.

Transmission Control Protocol (ARPANET) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

TCP

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. From Glossary of Distance Education and Internet Terminology http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

TCP

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. TCP Format: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Source Port | Destination Port | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Sequence Number | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Acknowledgment Number | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Data | |U|A|P|R|S|F| | | Offset| Reserved |R|C|S|S|Y|I| Window | | | |G|K|H|T|N|N| | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Checksum | Urgent Pointer | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Options | Padding | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | data | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Sequence Number^ The sequence number of the first byte within this packet. Acknowledgement Number^ The next expected sequence number of packets coming in the opposite direction. Reserved^ Not used. Note that this "field" is actually two fields: the low-order bits of the data offset byte and the high-order bits of the flags byte. Key point: The two undefined flags in this field are handled differently by different systems, which allows them to be fingerprinted URG^ The urgent flag is used to send what is known as out-of-band data. Key point: TCP/IP stacks often don't implement this right, and virtually no application uses it either. In fact, the WinNuke DoS attack against Windows was due to the fact that Windows would crash on URG data. ACK^ When set, the Acknowledgement Number field is valid. Key point: This bit is set in every packet but the first one, because every TCP packet acknowledges the last data it received. Key point: In order to block incoming connections, firewalls typically only pay attention to TCP packets with the ACK bit == 0. In other words, by blocking the first packet of a TCP connection, you prevent the connection from being established in the first place. Key point: Hackers can usually send TCP packets through a firewall by setting the ACK bit. Even though hackers cannot connect to a service, they can still do things like port scanning using this technique. PSH^ Normally, TCP tries to coalesce multiple packets into a single packet in order to improve throughput performance (handling one big chunk is more efficient than smaller chunks), but at the cost of latency (after receiving the first chunk, it must wait a little bit to see if a second chunk arrives). This bit tells the stack to push the data though immediately without waiting. RST^ Informs the other side that an error has occurred. This will either drop the connection or set it back to a known state. Key point: Different TCP/IP stacks send resets in response to different conditions, which can be used to fingerprint the stack. SYN^ Begins a connection. The most important consideration is synchronizing the sequence numbers on both sides. See SYN for more information. FIN^ Closes a connection. Key point: If you send a FIN packet to an open port, it should not respond. Some incorrectly written stacks respond anyway, allowing you to fingerprint a system. Key point: IDS systems monitoring network traffic will sometimes kill TCP sessions by spoofing a FIN packet. Thus, when it detects an intruder connected to a server, it will make the server think the intruder has hung-up, and the server will likewise hang-up. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

TCP sequence number prediction

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. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

TCP Transmission Control Protocol

(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.

tcp-wrappers

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.

TCP/IP (TCP/IP suite, TCP/IP stack)

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.

tcpdump

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/> From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tcpdump

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. From Redhat 8.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tcpflow

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'.

tcpquota

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tcpreplay

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tcpslice

tcpspy

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tcpstat

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. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tcptraceroute

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.

TCSEC (DoD Trusted Computer System Evaluation Criteria, CSC-STD-001-83, DoD 5200.28-STD)

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.

TELNET

/tel'net/ vt. (also commonly lowercased as `telnet') To communicate with another Internet host using the TELNET (RFC 854) protocol (usually using a program of the same name). TOPS-10 people used the word IMPCOM, since that was the program name for them. Sometimes abbreviated to TN /T-N/. "I usually TN over to SAIL just to read the AP News." From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Telnet

A network protocol that provides a remote command-line shell. Telnet was created in the early 1970s, and is still widely used (as of early 2000). The most common uses of Telnet are to remotely login to UNIX systems. It is also widely used to obtain a command-prompt on network equipment such as routers and switches. Misconception: The word Telnet is the name of both the protocol as well as the client-program that uses the protocol. This client program is built into most systems. Using the Telnet program, you can open up a raw TCP connection to any port on the target computer in order to interact directly with text-based protocols. Thus, when we talk about telnetting to a certain port, we usually are talking about simply opening a raw connection. Indeed, we may be referring to a case where neither the Telnet program nor protocol are being used, such as using netcat to port 80. Example: Telnet to your local SMTP using a command that looks like telnet smtp.example.com 25. The first parameter should be your own mail server, whereas the second parameter indicates which port to connect to (other than the default port 23). Now type in the text as you see it below: http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Telnet

An Internet protocol that enables Internet users to log on to another computer linked to the Internet, including those that cannot directly communicate with the internet's TCP/IP protocols. Telnet establishes a "plain vanilla" computer terminal called a network virtual terminal. This capability is frequently used to enable communications with bulletin boards systems (BBSs) and mainframe computers. For example, you will often see hyperlinks so Telnet sessions while browsing the World Wide Web (WWW) . If you click such a hyperlink, your browser starts a Telnet helper program, and you see a text-only command window. In this window, you type commands and see the remote system's responses. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

TERMCAP

TERMinal CAPability (Unix) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

termcap

The termcap package provides the /etc/termcap file. /etc/termcap is a database which defines the capabilities of various terminals and terminal emulators. Certain programs use the /etc/termcap file to access various features of terminals (the bell, colors, and graphics, etc.). From Mandrake 9.0 RPM http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

termcap-compat

Compatibility package for old termcap-based programs. The termcap-compat package provides the libtermcap.so.2 and /etc/termcap files which are required to run non-Debian, binary-only termcap-based programs. Since libc6-based programs are hopefully "modern" enough to be linked with ncurses (or slang), this package only provides a libc5-based libtermcap library. You do not need to install this package to run Debian-packaged programs since Debian GNU/Linux uses terminfo and not termcap. You need this package if a program (that you cannot recompile) fails to run with the error message "...: can't load library 'libtermcap.so.2'" or complains about a missing /etc/termcap file. The termcap-compat package isn't meant to be used to compile programs therefore it doesn't provide all the necessary files for compilation. If you want to compile a program that claims to need termcap, why not try ncurses's termcap emulation instead? It's as simple as linking with ncurses instead of libtermcap (i.e. replace the '-ltermcap' with '-lncurses' in the makefile). Ncurses' termcap emulation routines translate terminfo entries to termcap entries on the fly, so you don't even need an /etc/termcap file. This package provides: libtermcap.so shared library, version 2.0.8 termcap database, version 10.2.7 From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tetex

TeTeX is an implementation of TeX for Linux or UNIX systems. TeX takes a text file and a set of formatting commands as input and creates a typesetter-independent .dvi (DeVice Independent) file as output. Usually, TeX is used in conjunction with a higher level formatting package like LaTeX or PlainTeX, since TeX by itself is not very user-friendly.Install tetex if you want to use the TeX text formatting system. If you are installing tetex, you will also need to install tetex-afm (aPostScript(TM) font converter for TeX), tetex-dvilj (for converting.dvi files to HP PCL format for printing on HP and HP compatible printers), tetex-dvips (for converting .dvi files to PostScript format for printing on PostScript printers), tetex-latex (a higher level formatting package which provides an easier-to-use interface for TeX), and tetex-xdvi (for previewing .dvi files in X). Unless you are anexpert at using TeX, you should also install the tetex-doc package, which includes the documentation for TeX.

TeX

/tekh/ n. An extremely powerful macro-based text formatter written by Donald E. Knuth, very popular in the computer-science community (it is good enough to have displaced Unix troff, the other favored formatter, even at many Unix installations). TeX fans insist on the correct (guttural) pronunciation, and the correct spelling (all caps, squished together, with the E depressed below the baseline; the mixed-case `TeX' is considered an acceptable kluge on ASCII-only devices). Fans like to proliferate names from the word `TeX' -- such as TeXnician (TeX user), TeXhacker (TeX programmer), TeXmaster (competent TeX programmer), TeXhax, and TeXnique. See also CrApTeX. Knuth began TeX because he had become annoyed at the declining quality of the typesetting in volumes I-III of his monumental "Art of Computer Programming" (see Knuth, also bible). In a manifestation of the typical hackish urge to solve the problem at hand once and for all, he began to design his own typesetting language. He thought he would finish it on his sabbatical in 1978; he was wrong by only about 8 years. The language was finally frozen around 1985, but volume IV of "The Art of Computer Programming" is not expected to appear until 2002. The impact and influence of TeX's design has been such that nobody minds this very much. Many grand hackish projects have started as a bit of toolsmithing on the way to something else; Knuth's diversion was simply on a grander scale than most. TeX has also been a noteworthy example of free, shared, but high-quality software. Knuth offers a monetary awards to anyone who found and reported bugs dating from before the 1989 code freeze; as the years wore on and the few remaining bugs were fixed (and new ones even harder to find), the bribe went up. Though well-written, TeX is so large (and so full of cutting edge technique) that it is said to have unearthed at least one bug in every Pascal system it has been compiled with.

tex4ht

LaTeX and TeX for Hypertext (HTML) TeX4ht is a highly configurable TeX-based authoring system for producing hypertext. It interacts with TeX-based applications through style files and postprocessors, leaving the processing of the source files to the native TeX compiler. Consequently, TeX4ht can handle the features of TeX-based systems in general, and of LaTeX in particular. TeX4ht can be used both for authoring HTML using TeX/LaTeX input files, or for converting existing TeX input files (in any format) into HTML, with (usually) only minor modifications. You will need imagemagick suite of programs to convert from graphics in DVI files, as output by TeX (via postscript) to GIF, PNG or JPEG files. Alternatively, you could use ghostscript and programs from the netpbm package after adjusting TeX4ht's configuration. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Documentation system for on-line information and printed output Texinfo is a documentation system that uses a single source file to produce both on-line information and printed output. Using Texinfo, you can create a printed document with the normal features of a book, including chapters, sections, cross references, and indices. From the same Texinfo source file, you can create a menu-driven, on-line Info file with nodes, menus, cross references, and indices. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

texinfo

Texinfo is a documentation system that can produce both online informationand printed output from a single source file. Normally, you'd have to write two separate documents: one for online help or other online information and the other for a typeset manual or other printed work. Using Texinfo, you only need to write one source document. Then when the work needs revision, you only have to revise one source document. The GNU Project uses the Texinfo file format for most of its documentation. Install texinfo if you want a documentation system for producing both online and print documentation from the same source file and/or if you are going to write documentation for the GNU Project.

The editor allows you to write structured documents via a WYSIWYG (what-you-see-is-what-you-get) and user friendly interface. New styles may be created by the user. The program implements high-quality typesetting algorithms and TeX fonts, which help you to produce professionally looking documents. The high typesetting quality still goes through for automatically generated formulas, which makes TeXmacs suitable as an interface for computer algebra systems. TeXmacs also supports the Guile/Scheme extension language, so that you may customize the interface and write your own extensions to the editor. In the future, TeXmacs is planned to evolve towards a complete scientific office suite, with spreadsheet capacities, a technical drawing editor and a presentation mode.

text

n. 1. [techspeak] Executable code, esp. a `pure code' portion shared between multiple instances of a program running in a multitasking OS. Compare English. 2. Textual material in the mainstream sense; data in ordinary ASCII or EBCDIC representation (see flat-ASCII). "Those are text files; you can review them using the editor." These two contradictory senses confuse hackers, too. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

text

This word has multiple senses. Historically, it comes the standard English word meaning that main body of a printed or written work. For example, the text of a letter somebody sent you distinguishes the body of the letter from the envelope or the greeting. In cryptography, the word TEXT means anything you might want to encrypt, where the words plaintext indicates the message before you encrypt it and ciphertext indicates the message after you encrypt it. In other areas of computer science, there is text data and binary data. The phrase "text" generally means human readable data, such as English text, whereas the word binary indicates data that can only be read by the computer. Misunderstanding: We sometimes encrypt binary data, in which case the binary data forms that plain text of the message. Conversely, the body of a binary program that runs is often referred to as the TEXT of the program. In both these particular areas, the word "TEXT" is indicating the oppose meaning of the general usage. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Trivial File Transfer Protocol (UDP, RFC 1350/1782/1783/1784/1785) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

TFTP

Trivial File Transfer Protocol TFTP is a bare-bones protocol used by devices that boot from the network. It is runs on top of UDP, so it doesn't require a real TCP/IP stack. Misunderstanding: Many people describe TFTP as simply a trivial version of FTP. This misses the point. The purpose of TFTP is not to reduce the complexity of file transfer, but to reduce the complexity of the underlying TCP/IP stack so that it can fit inside boot ROMs. Key point: TFTP is almost always used with BOOTP. BOOTP first configures the device, then TFTP transfers the boot image named by BOOTP. Key point: Many systems come with unnecessary TFTP servers. Many TFTP servers have bugs, like the backtracking problem or buffer overflows. As a consequence, many systems can be exploited with TFTP even though virtually nobody really uses it. Key point: A TFTP file transfer client is built into many operating systems (UNIX, Windows, etc.). These clients are often used to download rootkits when being broken into. Therefore, removing the TFTP client should be part of your hardening procedure. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

A multithreaded program can run much faster than a monolithic, or single-threaded, program because several, or even many, different tasks can be performed concurrently, rather than serially (sequentially). Also, threads within a single application can share resources and pass data back and forth between themselves. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

threaded code

A technique for implementing virtual machine interpreters, introduced by J.R. Bell in 1973, where each op-code in the virtual machine instruction set is the address of some (lower level) code to perform the required operation.

thrust

a port of the classic Commodore 64 game The object of the game is to lift the Klystron Pod from the bottom of a cave and return it safely to space. The Pod is very heavy (compared to the ship) and this makes it tougher than it may seem. You must be careful not to run out of fuel, crash into the cave walls, or let the enemy artillery outposts shoot you down.

tiger teams (sneakers)

A team of "white-hats" attack and secure systems. Some of these teams are given the task to penetrate the systems, other are just to review security procedures with an eye of how they might be penetrated. This is a favorite of government and paranoid organizations. Controversy: Tiger teams aren't afraid of prosecution and start with a greater degree of knowledge about the victim. Therefore, many people argue whether a successful penetration by a tiger team reflects a real-world scenario. For example, if you don't fear prosecution, then you might simply do a physical break-in. A physical break-in will always result in a successful "hack" because you can install keystroke loggers, password sniffers, or simply steal disk drives. Controversy: There are some cases where tiger teams have actually stolen sensitive information. History: This originally a military term, where teams would enter secure installations and leave behind notes like "bomb" or "theft" in sensitive areas to prove that they had been there, and that they could have left behind bombs or stolen secret plans.

tmpreaper

Cleans up files in directories based on their age This package provides a program that can be used to clean out temporary-file directories. It recursively searches the directory, refusing to chdir() across symlinks, and removes files that haven't been accessed in a user-specified amount of time. You can specify a set of files to protect from deletion with a shell pattern. It will not remove files owned by the process EUID that have the `w' bit clear, unless you ask it to, much like `rm -f'. `tmpreaper' will not remove symlinks, sockets, fifos, or special files unless given a command line option enabling it to. WARNING: Please do not run `tmpreaper' on `/'. There are no protections against this written into the program, as that would prevent it from functioning the way you'd expect it to in a `chroot(8)' environment. The daily tmpreaper run can be configured through /etc/tmpreaper.conf . From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

toggle

vt. To change a bit from whatever state it is in to the other state; to change from 1 to 0 or from 0 to 1. This comes from `toggle switches', such as standard light switches, though the word `toggle' actually refers to the mechanism that keeps the switch in the position to which it is flipped rather than to the fact that the switch has two positions. There are four things you can do to a bit: set it (force it to be 1), clear (or zero) it, leave it alone, or toggle it. (Mathematically, one would say that there are four distinct boolean-valued functions of one boolean argument, but saying that is much less fun than talking about toggling bits.)

toolame

MPEG-1 layer 2 audio encoder toolame is a very fast (6x realtime on a 550mhz celeron) MPEG-1 layer 2 audio encoder with a command-line syntax nearly identical to that of the lame MPEG-1 layer 3 audio encoder. Because of patent issues surrounding the layer 3 encoder, the ability of most mpeg audio players to play layer 2 files, and the similarity in command-line syntax, toolame makes a very good drop-in replacement for lame or other layer 3 encoders under most circumstances.

traceroute

provides information concerning the route which packets must take to get from your computer (the server in this case) to a remote computer/server; typically used to diagnose possible problems in packet routing. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

traceroute

Traceroute is a command built into most systems that traces the path through the Internet between two points (on Windows, it is known as "tracert"). Every IP packet on the Internet has a Time-to-Live field. Each router subtracts one from this field when it forwards the packet. This was designed to solve the problem of "routing loops": routers get confused as to the proper network topology and end up routing packets in an infinite loop. The TTL field guarantees that these packets will eventually die on their own accord. When a packet dies in this fashion, the last router to see the packet sends a diagnostic message back to the sender informing of this fact. Consequently (and this is the genius part), you can purposely create small TTLs that are guaranteed to kill the packet. You set the TTL field first to 1, causing the first router to drop it and inform you. You set the TTL field to 2, causing the second router to drop it. You do this for all TTL values, getting back a notification from each router in the network, thus mapping the route between two points. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

traceroute

Traces the route taken by packets over a TCP/IP network. The traceroute utility displays the route used by IP packets on their way to a specified network (or Internet) host. Traceroute displays the IP number and host name (if possible) of the machines along the route taken by the packets. Traceroute is used as a network debugging tool. If you're having network connectivity problems, traceroute will show you where the trouble is coming from along the route. Install traceroute if you need a tool for diagnosing network connectivity problems. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Triple DES (3DES, 3DES_EDE)

A stronger form of DES where the algorithm is applied three times in order to encrypt data. Triple DES became necessary in the later part of the 20th century because DES had become so weak (a $200k machine was able to decrypt a DES encrypted message in hours). At that time, the new AES replacement had not yet appeared. In order to leverage DES hardware/software products, it was decided just to use DES three times with multiple keys. Point: Triple DES runs in "E-D-E" mode where it encrypts the data with the first key, then decrypts it with the second key, then encrypts with the third key. The second "decryption" phase is really just an encryption step: it is only by convention that one direction is considered encryption and the other direction decryption. The reason this technique is chosen is that if the same key is supplied three times, the effect is the same as a single encryption step. Controversy: The NSA urged banks not to adopt Triple-DES as a standard, citing national security concerns. They instead urged banks to adopt the Clipper chip. The banks went with Triple-DES in ANSI X9.52. In fact, as of 1998, several countries mandated the use of Triple-DES (replacing DES) in financial transactions. Controversy: Simply tripling the encryption does not necessarily triple its strength. For example, there are many crypto algorithms whereby encrypting with two different keys simply means you can decrypt with a single third key. Many suspect that tripling DES only doubles is cryptographic strength. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tripwire

Tripwire is a tool that detects when files have been altered by regularly recalculating hashes of them and storing the hashes in a secure location. The product triggers when changes to the files have been detected. By using cryptographic hashes, tripwire is often able to detect subtle changes. Contrast: The simplistic form of tripwire is to check file size and last modification time. However, programs that change files (like viruses) will often keep these the same. On the other hand, keeping complete backups would require too much space. Therefore, cryptographic hashes are used. Contrast: The cryptographic hash calculated from the file is often known as a "fingerprint" or "signature". However, these terms have completely different meanings in other areas of security, so some people just say "hash" or "checksum". History: The original tool was published in 1992 for Unix. The company Tripwire Inc. was formed in 1998. Point: Reasons why files change: Replace common system programs with duplicates contains backdoors. Change configuration files to allow intruder back into the system. Alter system logfiles in order to cover tracks. Alter data files (such as financial records or school grades).

troff

/T'rof/ or /trof/ n. [Unix] The gray eminence of Unix text processing; a formatting and phototypesetting program, written originally in PDP-11 assembler and then in barely-structured early C by the late Joseph Ossanna, modeled after the earlier ROFF which was in turn modeled after the Multics and CTSS program RUNOFF by Jerome Saltzer (that name came from the expression "to run off a copy"). A companion program, nroff, formats output for terminals and line printers. In 1979, Brian Kernighan modified troff so that it could drive phototypesetters other than the Graphic Systems CAT. His paper describing that work ("A Typesetter-independent troff," AT&T CSTR #97) explains troff's durability. After discussing the program's "obvious deficiencies -- a rebarbative input syntax, mysterious and undocumented properties in some areas, and a voracious appetite for computer resources" and noting the ugliness and extreme hairiness of the code and internals, Kernighan concludes: None of these remarks should be taken as denigrating Ossanna's accomplishment with TROFF. It has proven a remarkably robust tool, taking unbelievable abuse from a variety of preprocessors and being forced into uses that were never conceived of in the original design, all with considerable grace under fire. The success of TeX and desktop publishing systems have reduced troff's relative importance, but this tribute perfectly captures the strengths that secured troff a place in hacker folklore; indeed, it could be taken more generally as an indication of those qualities of good programs that, in the long run, hackers most admire.

trojan

A class of malware, the word trojan refers to the classic Trojan Horse from the Iliad. In this story, after giving up on sieging the fortified city of Troy, the Greeks left behind a present. This consisted of a large wooden horse left at the outskirts of the town. After seeing the Greeks sail off, the citizens brought the wooden horse into town. The horse contained Greek warriors, who promptly jumped out, killed a bunch of people, and opened the city gates, letting in the Greek army who had actually been hiding rather than sailing off with the ships. Trojans are one of the leading causes of breaking into machines. If you pull down a program from a chat room, new group, or even from unsolicited e-mail, then the program is likely trojaned with some subversive purpose. It might contain a virus, a password-grabber, or consist of a remote admin trojan designed to allow remote control over your machine. Contrast: Whereas the general popular uses the word virus to refer to any malware, a Trojan is not technically a virus. Generally, Trojans do not spread to other programs or other machines. Key point: The word can be used as a verb. To trojan a program is to add subversive functionality to an existing program. For example, a trojaned login program might be programmed to accept a certain password for any user's account that the hacker can use to log back into the system at any time. Rootkits often contain a suite of such trojaned programs. Key point: Users can often break into a system by leaving behind trojaned command programs in directories (like their own directory or the /tmp directory). If you copy your own ls program to the /tmp directory, and somebody else does a cd /tmp then an ls, that user will run your program with their own privileges. This is especially dangerous against root, which is why the local directory should not be part of the search path for the root account. Contrast: A big fear is the transitive trojan -- a trojan horse that generates other trojans. The best example is the trojan described by Ken Thompson. He put a trojan horse into the C compiler so that when the login code was compiled, it would always accept a backdoor password. A common technique to guard against that is to first recompile the compiler first. Thompson therefore trojaned the compiler so that when it recompiled itself, it would put back the trojan. Therefore, even when you had the complete source to UNIX and compiler, you still couldn't recompile from scratch and remove the trojan. The fear is that tool vendors might put such trojans in their compilers, which cause products made from those compilers to have backdoors.

Trojan Horse

A computer program is either hidden inside another program or that masquerades as something it is not in order to trick potential users into running it. For example a program that appears to be a game or image file but in reality performs some other function. The term "Trojan Horse" comes from a possibly mythical ruse of war used by the Greeks sometime between 1500 and 1200 B.C. A Trojan Horse computer program may spread itself by sending copies of itself from the host computer to other computers, but unlike a virus it will (usually) not infect other programs.

trscripts

Scripts for reencoding text files and BDF-fonts. The script `trbdf' can convert a BDF font from one codeset to another. The script `trcs' reencodes text files from one codeset to another. It can generate scripts for `tr'. For example the command trcs --from cp1252 --to latin1 --gen-script gives you the following output: #!/bin/sh trap "exit 0" PIPE cat "$@" | tr \ '\200''\201''\202''\203''\204''\205''\206''\207''\210''\211''\212'\ '\213''\214''\215''\216''\217''\220''\221''\222''\223''\224''\225'\ '\226''\227''\230''\231''\232''\233''\234''\235''\236''\237' \ '\105''\77''\47''\146''\42''\267''\53''\77''\136''\77''\123'\ '\253''\117''\77''\132''\77''\77''\47''\47''\42''\42''\267'\ '\-''\-''\176''\77''\163''\273''\157''\77''\172''\131' Both scripts try to approximate the missing from the target codeset symbols.

TrueType Fonts

A wide variety of fonts designed to be printer-independent, unlike PostScript fonts. Available for the Apple Macintosh and Windows. Not commonly used with UNIX/Linux. (Also, see BDF Fonts and PostScript Fonts.) From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

trust

The word trust has a huge amount of significance within the infosec community. The most immediately connotation is the use of this word instead of "secure". Government standards talk about Trusted Systems rather than secure systems. This is a zen way at looking at security. The main issue hinges around to what degree you can trust systems. If you store confidential information on a computer, you are placing your trust in that computer. More importantly, you are trusting the people/organization that operates that system. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

trustees

Advanced permission management system for Linux. The main goal of Linux trustees project is to create an advanced permission management system for linux. In fact, UNIX permission system is not suitable for solution of very common tasks. E.g., let a system administrator wants to create a directory that available for some groups in write mode, for another groups - in read only. The files in the directory and subdirectories should inherits the parent's behavior, unless other is stated explicitly. Using standard UNIX (and Linux) security model it is generally speaking impossible to implement the situation when different groups have read/write and read/only permissions. This issue can be resolved by ext2-fs ACL project, but the problem is that nobody wants to copy mask or ACLs from parent directory to subdirectories either by hands or using special scripts. Using the trustees, you can resolve this problems just typing [/device]/path:+group1:REBX The solution proposed is mainly inspired by Novell Netware approach and Java security API. Special objects (called trustees) can be bounded to every file or directory. Trustee object means that access to file or directory or directory with subdirectories is granted (or denied) to certain user or group (or all except user or group). This package provides settrustee utility, which enables new privileges from trustee.conf. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

tunnel

A way of establishing an outbound connection through a firewall in such a way that it is neither blocked or monitored. This isn't a way of breaking through a firewall, but assuming you've compromised a machine on the other side of a firewall (through some other technique), this will allow you to communicate with that machine from the Internet. It is also used by people behind firewalls that use restrictive rulesets: users simply create a tunnel back to their home machine. Example: People have written tunnels over ICMP, DNS, HTTP, e-mail messages, and TCP connections. Tunnels can either by of the "port redirector" style (which run on top of any TCP/IP stack) or of the network interface variety (below the TCP/IP stack requiring kernel mod).

Encrypted network connection within a TCP/IP connection Tunnel Vision creates a "virtual" TCP/IP network (VPN) between two Tunnel Vision-capable sites on the internet. It uses the strongest encryption that's actually useful (1024-bit RSA and 128-bit Blowfish) to protect your data along the way. This connection between two TV servers is called a "tunnel." Tunnel Vision is usually used on a router or gateway machine. When someone on your network wants to send data to someone on the other side of the tunnel, it sends through the default gateway (the TV server) like it normally would. You configure the TV server to send data through the tunnel instead of just forwarding it onto the internet. Tunnel Vision requires Linux 2.1.122 or higher with the ethertap and netlink devices.

Tux

Tux the Penguin is the official emblem of Linux, This eventuated after a logo contest in 1996, during which Linus Torvalds endorsed the idea of a penguin logo in a couple of famously funny postings. Linus explained that he was once bitten by a killer penguin in Australia and has felt a special affinity for the species ever since. (Linus has since admitted that he was also thinking of Feathers McGraw, the evil-genius penguin jewel thief who appeared in a Wallace & Grommit feature cartoon, "The Wrong Trousers".) Larry Ewing designed the official Tux logo. It has proved a wise choice, amenable to hundreds of recognizable variations used as emblems of Linux-related projects, products, and user groups. In fact, Tux has spawned an entire mythology, of which the Gospel According to Tux and the mock-epic poem "Tuxowolf" are among the best-known examples. There is a `real' Tux - a black-footed penguin resident at the Bristol Zoo. Several friends of Linux bought a zoo sponsorship for Linus as a birthday present in 1996.

tweak

vt. 1. To change slightly, usually in reference to a value. Also used synonymously with twiddle. If a program is almost correct, rather than figure out the precise problem you might just keep tweaking it until it works. See frobnicate and fudge factor; also see shotgun debugging. 2. To tune or bum a program; preferred usage in the U.K. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

twiddle

n. 1. Tilde (ASCII 1111110, ~). Also called `squiggle', `sqiggle' (sic -- pronounced /skig'l/), and `twaddle', but twiddle is the most common term. 2. A small and insignificant change to a program. Usually fixes one bug and generates several new ones (see also shotgun debugging). 3. vt. To change something in a small way. Bits, for example, are often twiddled. Twiddling a switch or knobs implies much less sense of purpose than toggling or tweaking it; see frobnicate. To speak of twiddling a bit connotes aimlessness, and at best doesn't specify what you're doing to the bit; `toggling a bit' has a more specific meaning (see bit twiddling, toggle). 4. Uncommon name for the twirling baton prompt. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

twirling baton

n. [PLATO] The overstrike sequence -/|\-/|\- which produces an animated twirling baton. If you output it with a single backspace between characters, the baton spins in place. If you output the sequence BS SP between characters, the baton spins from left to right. If you output BS SP BS BS between characters, the baton spins from right to left. This is also occasionally called a twiddle prompt. The twirling baton was a popular component of animated signature files on the pioneering PLATO educational timesharing system. The archie Internet service is perhaps the best-known baton program today; it uses the twirling baton as an idler indicating that the program is working on a query. The twirling baton is also used as a boot progress indicator on several BSD variants of Unix; if it stops you're probably going to have a long and trying day.

type1inst

Install Adobe Type 1 fonts into X11 and Ghostscript type1inst is a small perl script which generates the "fonts.scale" file required by an X11 server to use any Type 1 PostScript fonts which exist in a particular directory. It gathers this information from the font files themselves, a task which previously was done by hand. The script is also capable of generating the similar "Fontmap" file used by ghostscript. It can also generate sample sheets for the fonts. The xutils package contains a utility called makepsres, which creates output in a different format but which may nevertheless be more useful.
