GNU R statistical computing language and environment R is `GNU S' - A language and environment for statistical computing and graphics. R is similar to the award-winning S system, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, ...). R is designed as a true computer language with control-flow constructions for iteration and alternation, and it allows users to add additional functionality by defining new functions. For computationally intensive tasks, C, C++ and Fortran code can be linked and called at run time. S is the statistician's Matlab and R is to S what Octave is to Matlab. This packages is a meta-package which eases the transition from the pre-1.5.0 package setup with its larger r-base package. Once installed, it can be safely removed and apt-get will automatically upgrade its components during future upgrades. Providing this packages gives a way to users to then only install r-base-core (but not, say, r-base-latex) if they so desire.

Security Tool to audit remote systems Remote Access Session is a security tool to analyze the integrity of systems. The program tries to gain access to a system using the most advanced techniques of remote intrusion. It lets to work on normal mode (fast) and hard mode (more intensive). There is a big difference between "Remote Access Session" and other remote security audit tools: If "Remote Access Session" find a remote vulnerability that gives user account or root, it will try to exploit it and it will return a shell in order to discard false positives. It is actually under development and it just has a few features of the future final version: *Advanced scanning capabilities. This tool doesn't block against firewall and it's fast. *Total service's banner info added: Includes web server detection version and named version, and the classical too (ftp, pop ...) *Writes reports with info of the host analyzed to the hard disk. *Remote OS detect feature with QueSO. *If detects any vulnerability, the tool chooses the right exploits based on version, vendor and OS of the services that run on the remote host and ask you on a interactive way if you want to run these exploits in order to check the real danger the remote host can receive and discard false positives.

Remote Authentication Dial-In User Service (RFC 2138) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Remote Authentication Dial-In user Service. A standard for authentication and accounting, RADIUS is primarily used to control dial-up access to PPP and other services. The protocal was standardized in RFC 2058, the current implementation is defined in RFCs 2138 and 2139. RADIUS uses UDP packets, older servers use ports 1645 and 1646, the current standard is port 1812 for authentication and 1813 for accounting. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
RADIUS allows distributed "modem pools" to use the same authentication server. When a user dials-up to an ISPs, the username/password is transmitted across the Internet to the central RADIUS server. This allows an ISP to easily manage many dialin locations. Key point: Since its humble beginnings, RADIUS has spread to become a generic remote authentication service. For example, it is becoming the desired standard to fix IEEE 802.11 wireless authentication problems. random http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
/bin/login replacement which uses the RADIUS protocol for authentication. Radiusclient is a /bin/login replacement which gets called by a getty to log in a user and to setup the user's login environment. Normal login programs just check the login name and password which the user entered against the local password file (/etc/passwd, /etc/shadow). In contrast to that Radiusclient also uses the RADIUS protocol to authenticate the user. This is the main binary archive.

Router Advertisement Daemon IPv6 has a lot more support for autoconfiguration than IPv4. But for this autoconfiguration to work on the hosts of a network, the routers of the local network have to run a program which answers the autoconfiguration requests of the hosts.

A group of hard disks under the control of array management software that work together to improve performance and decrease the odds of losing data due to mechanical or electronic failure by using such techniques as data striping. RAID implementations, because of their complexity and steep cost, are most often used on network servers. Several RAID levels exist, each with advantages and disadvantages. See RAID level 0 through RAID level 53. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Redundant Array of Independent / Inexpensive Disks (HDD, RAID) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Redundant Array of Inexpensive Disks - a method whereby information is spread across several disks, using techniques such as disk striping (RAID Level 0) and disk mirroring (RAID level 1) to achieve redundancy, lower latency and/or higher bandwidth for reading and/or writing, and recoverability from hard-disk crashes. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
see redundant arrays of independent disks (RAID). From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A method of providing data redundancy, improved performance and/or quick data recoverability from disk crashes, by spreading or duplicating data across multiple disk drives. Commonly used RAID types include RAID 0 (Data Striping), RAID 1 (Disk Mirroring) and RAID 5 (Striping with Distributed Parity). RAID configurations typically require SCSI disk drives (not IDE/EIDE) and may require identical drives (same capacity, brand, etc.). RAID arrays appear to the operating system as a single device. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

See RAID level 10. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A redundant array of inexpemive disks (RAID) scheme involving an array of two hard disks with identical contents. RAID level 1 does not employ data striping, so it offers no speed advantage and is not economical. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A redundant array of inexpensive disks (RAID) implementation that combines the data striping of RAID level 0 with the data-redundancy of RAID level 1. RAID level 10 array have high performance, but are not economical. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A redundant array of inexprnsive disks (RAID) scheme that uses data striping over an array of as many as a bard disks. Several of the drives in the array have copies of data that exist elsewhere, enabling them to catch and fix errors in the outgoing data stream. RAID level 2 is one of the most popular implementations. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A redundant array of inexpemive disks (RAID) implementation very similar to RAID levels 2, in which the level disks that contain the copies of data that appears elsewhere can detect but not fix errors in the outgoing data stream. Though RAID level 3 is slightly slower than RAID level 2 when errors occur, modern hard disks rarely make errors. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A redundant array of inexprnsive disks (RAID) implementation that distributes copies of sectors across an array of hard disked and uses one drive to check for, but not correct, errors in the outgoing data stream. RAID level 4's sector-copying technique is a special type of data striping. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The most commonly used redundant array of inexpensive disks (RAID) implementation. RAID level 5 uses a sector-based data striping scheme like RAID level 4, but does ant require a special data-checking disk since it distributes that function across the entire array as well. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A redundant array of inexpensive disks (RAID) scheme that uses data striping on two separate RAID level 3 arrays RAID level 53 arrays are very fast and quite fault-tolerant. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A redundant array of inexpensive disks (RAID) implementation that allows two hard disks to fail without loss of data and boasts very good data-reading performance, but also has poor data-writing performance. RAID level 6 is similar to RAID level 5, except that it distributes two copies of the error-checking data across the array. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
The raidtools package includes the tools you need to set up and maintain a software RAID device (using two or more disk drives in combination for fault tolerance and improved performance) on a Linux system.

Utilities to support 'old-style' RAID disks The Multiple Device driver's main goal is to group several disks or partitions together, making them look like a single block device. This includes linear adding of disks, RAID-0, RAID-4 and -5. If you are creating new RAID arrays, the raidtools2 package and newer RAID drivers may be a better choice. This package may only installed on systems with a kernel version higher than 2.1.62. With kernels from the 2.4 series or newer, or with 2.2 kernels with the 'new-style' RAID-patches, you should use raidtools2 instead.

spam-catcher using a collaborative filtering network Vipul's Razor is a distributed, collaborative, spam detection and filtering network. Razor establishes a distributed and constantly updating catalogue of spam in propagation. This catalogue is used by clients to filter out known spam. On receiving a spam, a Razor Reporting Agent (run by an end-user or a troll box) calculates and submits a 20-character unique identification of the spam (a SHA Digest) to its closest Razor Catalogue Server. The Catalogue Server echos this signature to other trusted servers after storing it in its database. Prior to manual processing or transport-level reception, Razor Filtering Agents (end-users and MTAs) check their incoming mail against a Catalogue Server and filter out or deny transport in case of a signature match. Catalogued spam, once identified and reported by a Reporting Agent, can be blocked out by the rest of the Filtering Agents on the network.

Tool to Query RBL Servers This program is a very basic interface to DNS listings such as the RBL filter developed by Paul Vixie and the MAPS project. The basic idea of the filter is that when someone is blacklisted for email abuse of some sort, a new domain name is resolved of the form "2.0.0.127.domain.name.com", where 2.0.0.127 is the abusive IP address in reverse (for example, 2.0.0.127 would be the IP address 127.0.0.2), and "domain.name.com" is the base domain name of the filtering service (such as "blackholes.mail-abuse.org" for the MAPS project RBL filter).

A popular symmetric block-cipher alogirthm created by Ron Rivest>. It allows keys between 1 and 2048 bits, though most implementations limits keys to 40-bits due to historic export controls.

Ron's Code 2/4 (cryptography), "RC2/4" From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A symmetric stream cipher developed by RSA Data Security, Inc.. Whereas most ciphers have been optimized for hardware (e.g. DES), RC4 was optimized for software. Applications: SSL, which means RC4 is built into your Netscape and Microsoft web browser. CDPD (Cellular) connections for your Palm modem using OmniSky. Lotus Notes, MS Access, Adobe Acrobat, PPTP, Oracle Secure SQL. IEEE 802.11 WEP Key point: RC4 supports variable length keys (up to 2048-bits), but most uses are 40-bits due to historic export controls. History: The algorithm was a trade-secret until 1994 when somebody reverse engineered it and anonymously posted it to the cypherpunks list and USENET. This reverse engineered version is known as "Arcfour" or "ARC4", which stands for "Alleged RC4". It isn't patented. Therefore, RSA Inc. is trying to move all its customers to RC5, which is both patented and copyrighted. The source code is essentially: while (length--) { x++; sx = state[x]; y += sx; sy = state[y]; state[y] = sx; state[x] = sy; *data++ ^= state[(sx+sy)&0xFF];} RSA Inc. still claims that it is a trade secret; however, due to its simplicity, its description is in virtually all crypto textbooks -- it is the most widely known secret on the net. Key point: RC4 works by XORing the plain-text against a stream of random numbers. Unless a whitening seed is provided at the begining, the plain-text may be recovered. This is a common bug in products. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

The first contest used a 56-bit key, took 212 days to crack by http://www.distributed.net/ using a total of roughly 1-million computers trying all possible 35,000,000,000,000,000 combinations. The message was "It is time to move to a longer key length.", and it was encrypted using the key 0x532B744CC20999. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Besides supporting all the basic Direct Connect commands such as downloading, searching, uploading, resuming, multihub search etc RCCP can be scripted. Selected scripts from many included with the package: * multi hub spider search * last seen user script (ala irc !seen script) * list all files from all users * download bot - watches query results and downloads all of them * segmented downloading * ... plus many more ... Direct Connect protocol is intended for peer-based file-sharing. In practise it works better than gnutella and other similar systems as it allows dc hubs (servers) administators to require clients to share specified amount of data. The amount is usually based on type of client's connection and it is used not to hurt or exclude anybody but to make file sharing "fair play".

Overview of RCS. RCS, the revision control system, is a suite of programs that tracks changes in text files and controls shared access to files in work group situations. It is generally used to maintain source code modules. It lends itself to tracking revisions of document files as well. RCS was written by Walter F. Tichy and Paul Eggert. The latest version which has been ported to Linux is RCS Version 5.7. There is also a semi-official, threaded version available. Much of the information in this HOWTO is taken from the RCS man pages. RCS includes the rcs(1) program, which controls RCS archive file attributes, ci(1) and co(1), which check files in and out of RCS archives, ident(1), which searches RCS archives by keyword identifiers, rcsclean(1), a program to clean up files that are not being worked on or haven't changed, rcsdiff(1), which runs diff(1) to compare the revisions, rcsmerge(1), which merges two RCS branches into a single working file, and rlog(1), which prints RCS log messages. Files archived by RCS may be text of any format, or binary if the diff program used to generate change files handles 8-bit data. Files may optionally include identification strings to aid in tracking by ident(1). RCS uses the utilities diff(1) and diff3(3) to generate the change files between revisions. A RCS archive consists of the initial revision of a file, which is version 1.1, and a series of change files, one for each revision. Each time a file is checked out of an archive with co(1), edited, and checked back into the archive with ci(1), the version number is increased, for example, to 1.2, 1.3, 1.4, and so on for successive revisions. The archives themselves commonly reside in a ./RCS subdirectory, although RCS has other options for archive storage. For an overview of RCS, see the rcsintro(1) manual page.

Backup program to use deltas for history rdiff-backup is a script that backs up one directory to another. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, symlinks, special files, permissions, uid/gid ownership (if it is running as root), and modification times. Finally, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted.

In jargon, refers to doing something while people are watching or waiting. "I asked her how to find the calling procedure's program counter on the stack and she came up with an algorithm in real time." From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

n. 1. A commercial user. One who is paying real money for his computer usage. 2. A non-hacker. Someone using the system for an explicit purpose (a research project, a course, etc.) other than pure exploration. See user. Hackers who are also students may also be real users. "I need this fixed so I can do a problem set. I'm not complaining out of randomness, but as a real user." See also luser. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
n. 1. Those institutions at which `programming' may be used in the same sentence as `FORTRAN', `COBOL', `RPG', `IBM', `DBASE', etc. Places where programs do such commercially necessary but intellectually uninspiring things as generating payroll checks and invoices. 2. The location of non-programmers and activities not related to programming. 3. A bizarre dimension in which the standard dress is shirt and tie and in which a person's working hours are defined as 9 to 5 (see code grinder). 4. Anywhere outside a university. "Poor fellow, he's left MIT and gone into the Real World." Used pejoratively by those not in residence there. In conversation, talking of someone who has entered the Real World is not unlike speaking of a deceased person. It is also noteworthy that on the campus of Cambridge University in England, there is a gaily-painted lamp-post which bears the label `REALITY CHECKPOINT'. It marks the boundary between university and the Real World; check your notions of reality before passing. This joke is funnier because the Cambridge `campus' is actually coextensive with the center of Cambridge town. See also fear and loathing, mundane, and uninteresting.

English text speech synthesizer Recite is a program to do speech synthesis. The quality of sound produced is not terribly good, but it should be adequate for reporting the occasional error message verbally. Given some English text, recite will convert it to a series of phonemes, then convert the phonemes to a sequence of vocal tract parameters, and then synthesise the sound a vocal tract would make to say the sentence. Recite can perform a subset of these operations, so it can be used to convert text into phonemes, or to produce an utterance based on vocal tract parameters computed by some other program.

Undelete files on ext2 partitions Recover automates some steps as described in the ext2-undeletion howto. This means it seeks all the deleted inodes on your hard drive with debugfs. When all the inodes are indexed, recover asks you some questions about the deleted file. These questions are: * Hard disk device name * Year of deletion * Month of deletion * Weekday of deletion * First/Last possible day of month * Min/Max possible file size * Min/Max possible deletion hour * Min/Max possible deletion minute * User ID of the deleted file * A text string the file included (can be ignored) If recover found any fitting inodes, it asks to give a directory name and dumps the inodes into the directory. Finally it asks you if you want to filter the inodes again (in case you typed some wrong answers). From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

REGular EXpressions (GREP, EMACS, ...) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
/reg'eksp/ n. [Unix] (alt. `regex' or `reg-ex') 1. Common written and spoken abbreviation for `regular expression', one of the wildcard patterns used, e.g., by Unix utilities such as grep(1), sed(1), and awk(1). These use conventions similar to but more elaborate than those described under glob. For purposes of this lexicon, it is sufficient to note that regexps also allow complemented character sets using ^; thus, one can specify `any non-alphabetic character' with [^A-Za-z]. 2. Name of a well-known PD regexp-handling package in portable C, written by revered Usenetter Henry Spencer <henry@zoo.toronto.edu>.

REmote Graphics Instruction Set From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
n. Many older processor architectures suffer from a serious shortage of general-purpose registers. This is especially a problem for compiler-writers, because their generated code needs places to store temporaries for things like intermediate values in expression evaluation. Some designs with this problem, like the Intel 80x86, do have a handful of special-purpose registers that can be pressed into service, providing suitable care is taken to avoid unpleasant side effects on the state of the processor: while the special-purpose register is being used to hold an intermediate value, a delicate minuet is required in which the previous value of the register is saved and then restored just before the official function (and value) of the special-purpose register is again needed.

A set of symbols, including text and metacharacters, used to search for text. The most common components are the period (.), which matches one character; the asterisk (*), which matches any number of characters; and brackets ([string]), which list a set of characters to be matched. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
A regular expression is a sequence of characters that forms a template used to search for strings [Words, phrases, or just about any sequence of characters. ] within text. In other words, it is a search pattern. To get an idea of when you would need to do this, consider the example of having a list of names and telephone numbers. If you want to find a telephone number that contains a 3 in the second place and ends with an 8, regular expressions provide a way of doing that kind of search. Or consider the case where you would like to send an email to fifty people, replacing the word after the ``Dear'' with their own name to make the letter more personal. Regular expressions allow for this type of searching and replacing. From Rute-Users-Guide http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

In file system navigation, a path to a file or directory as it relates to a user's or program's current directory location. From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
Commands can be given file name arguments in two ways. If you are in the same directory as the file (i.e., the file is in the current directory), then you can just enter the file name on its own (e.g., cp my_file new_file). Otherwise, you can enter the full path name, like cp /home/jack/my_file /home/jack/new_file. Very often administrators use the notation ./my_file to be clear about the distinction, for instance, cp ./my_file ./new_file. The leading ./ makes it clear that both files are relative to the current directory. File names not starting with a / are called relative path names, and otherwise, absolute path names.

E-mail relay is where spammers hijack an e-mail server in order to forward their spam through the server. Usually, the spammer (from the Internet) sends the e-mail server a single e-mail with thousands of recipients. Similarly, any open USENET server can be hijacked to relay spam to newsgroups. Key point: This allows a spammer with a dial-up account to send e-mail as fast as a high-speed Internet connection, since it is the victim who breaks apart the recipient list and sends each person a separate copy. Therefore, one e-mail goes into the server, thousands come out. Key point: Relaying can be turned off in the e-mail server configuration. Such configuration will force the server to accept either incoming mail, or outgoing mail, but not incoming e-mail destined back out to the Internet. There are several sites on the Internet that will scan your corporate e-mail server to see if will relay spam. Key point: Some e-mail relays are completely open, others are closed to open relaying, but have bugs that can be exploited in order to relay spam.

Emacs mode to help find relevant texts The Remembrance Agent is one of the projects being developed by the MIT Media Lab's software agents group.
