C a programming language designed by Dennis Ritchie during the early 1970s and immediately used to reimplement Unix; so called because many features derived from an earlier compiler named `B' in commemoration of its parent, BCPL. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html C n. 1. The third letter of the English alphabet. 2. ASCII 1000011. 3. The name of a programming language designed by Dennis Ritchie during the early 1970s and immediately used to reimplement Unix; so called because many features derived from an earlier compiler named `B' in commemoration of its parent, BCPL. (BCPL was in turn descended from an earlier Algol-derived language, CPL.) Before Bjarne Stroustrup settled the question by designing C++, there was a humorous debate over whether C's successor should be named `D' or `P'. C became immensely popular outside Bell Labs after about 1980 and is now the dominant language in systems and microcomputer applications programming. See also languages of choice, indent style. C is often described, with a mixture of fondness and disdain varying according to the speaker, as "a language that combines all the elegance and power of assembly language with all the readability and maintainability of assembly language". From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html C programming language Point: The language is quirky, difficult for beginners to learn, and really just an accident of history. Despite this, one must grok the language in order to become an elite hacker. Key point: The large number of buffer overflow exploits is directly related to poor way that C protects programmers from doing the wrong thing. On the other hand, these lack of protections leads directly to its high speed. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html C Shell A Linux shell written to look sort of like the C programming language. It prompts you with %. Its program name is csh. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html C++ /C'-pluhs-pluhs/ n. Designed by Bjarne Stroustrup of AT&T Bell Labs as a successor to C. Now one of the languages of choice, although many hackers still grumble that it is the successor to either Algol 68 or Ada (depending on generation), and a prime example of second-system effect. Almost anything that can be done in any language can be done in C++, but it requires a language lawyer to know what is and what is not legal-- the design is almost too large to hold in even hackers' heads. Much of the cruft results from C++'s attempt to be backward compatible with C. Stroustrup himself has said in his retrospective book "The Design and Evolution of C++" (p. 207), "Within C++, there is a much smaller and cleaner language struggling to get out."

Most often applied to processor-memory access but also used for a local copy of data accessible over a network etc. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Cache A storage area that keeps frequently accessed data or program instructions readily available so that you don't have to retrieve them repeatedly from slow storage. Caches improve storage by storing data or instructions in faster sections of memory and by using efficient design to increase the likelihood that the data needed next is in the cache. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cache A temporary storage area for currently-used or recently-accessed data. Cache can be system-level (residing in dedicated cache memory on the motherboard or physically etched on the central processing unit) or disk-based (residing in main memory such as a hard disk drive or RAM). From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cache In general computer science, the word cache means simply to keep things around in case they are used again. For example, when you log onto your system, your username and password are stored in a cache in memory, because they are repeatedly used by the system every time you access a resource. Key point: Sometimes systems can be exploited through the cache. Examples are: HTTP proxy servers Companies use these so that thousands of users can share a single Internet connection. They store recently used webpages so that when multiple users access the same web-site, the proxy server only has to go across the link once in order to fetch the page for all the users. A never ending series of bugs leads to conditions whereby when one user logs into a website, other users can see that first user's data. Web-browser history/file cache Once a hacker breaks into a machine, he/she can view the history cache (list of URLs) or file cache (the actual contents of the web-sites) in order to spy on where the user has been. Embarrassing, inadvertent disclosure of this information by users with certain surfing habits is common. Web-browser cookie cache Lots of web-sites store passwords within cookies, so that stealing somebody's cookie information will allow a hacker to log in as that user.

[techspeak] To spew an entire file to the screen or some other output sink without pause (syn. blast). 2. By extension, to dump large amounts of data at an unprepared target or with no intention of browsing it carefully. Usage: considered silly. Rare outside Unix sites. See also dd, BLT. Among Unix fans, cat(1) is considered an excellent example of user-interface design, because it delivers the file contents without such verbosity as spacing or headers between the files, and because it does not require the files to consist of lines of text, but works with any sort of data. Among Unix haters, cat(1) is considered the canonical example of bad user-interface design, because of its woefully unobvious name. It is far more often used to blast a file to standard output than to concatenate two files. The name cat for the former operation is just as unintuitive as, say, LISP's cdr. Of such oppositions are holy wars made.... See also UUOC. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html catalog Tool to create,maintain and display Yahoo! like directories. Catalog is a perl program that allows to create, maintain and display Yahoo! like directories. The user interface is 100% HTML. It requires a MySQL database to run. The general idea behind the design of Catalog is that creating a catalog is mainly a matter of organizing objects in a structured tree. For Catalog the objects are records in a table of the SQL database. The structured tree is a set of tree nodes and relations between these nodes. The maintainer of the catalog is in charge of building the tree and placing objects in this tree. Here is a short list of the functions provided by Catalog: * Display structured trees of resources. * Display chronologically ordered resources and associated calendar. * Display alphabetical indexes of resources. * Allow full text search in the resources and the category names. * Powerful HTML based administration of catalogs. * On-Line editing of resource records. * Handle an arbitrary number of catalogs. * High performances using mod_perl and Apache. * Easy customization of the user view using HTML template files. * It is possible to define more than one view of the same catalog. * Load and unload a thematic catalog in XML. * Create an HTML dump of a structured tree to publish a static version. * Complete documentation including a guide and a reference manual. * Ready to use example.

Describes a condition of suspended animation in which something is so wedged or hung that it makes no response. If you are typing on a terminal and suddenly the computer doesn't even echo the letters back to the screen as you type, let alone do what you're asking it to do, then the computer is suffering from catatonia (possibly because it has crashed). "There I was in the middle of a winning game of nethack and it went catatonic on me! Aaargh!" Compare buzz.

It aims to generate high-quality output that reproduces all aspects of the DVI file within the limits of the output medium. CatDVI uses Unicode internally and can output ASCII, ISO Latin 1 and UTF-8 Unicode. CatDVI can be used for previewing TeX documents on character-cell displays such as traditional terminals and terminal emulators. It is also possible to use it in generation of plain text documents from TeX source, assuming that the document is written with this conversion in mind. CatDVI is under development and as such yet incomplete. However, it is quite useful even in its current form and already outperforms some of its competition in some areas. CatDVI requires that the TFM files for all fonts used in its input DVI files are installed or can be generated by kpathsea.

The CDcontrol is the first burning system of that type that I know for *nix operating system and it's all under GPL license. Some of it's features are better than commercial systems that I've hear about (and fully support CD images and all data type supported by cdrecord program), one of these features is the separated control of each recorder once the recording is started (avoid problems due a fail or speed problem in other writers). The CDcontrol itself has a daily production report for each writter and fails of writting, in cases of more serious errors, a technical report is also written (it's content is a full cdrecord output for that writter, plus the time when it happens). Other interesting feature is the automatic calculation of copies, enabling only the writers requested to complete the number and skipping all that are disabled. The CDcontrol come with the following tools: cd-memoria - Read the CD image and write it on the permanent memory (HD, Raid, CDRW, etc). memoria-cd - Read the CD image and write it on all writers. apagar-cdcontrol - Delete a CD image from permanent memory config-cdcontrol - Allow you to manually enable/disable one or more writers. rel-cdcontrol - Allow you to read the success/fail reports of each day (the technician report is found at the subdirectory $LOG_DIR/tec and should be read as any text file in the system).

It will break debconf. You have been warned! From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cdecl Turn english phrases to C or C++ declarations Cdecl is a program which will turn English-like phrases such as "declare foo as array 5 of pointer to function returning int" into C declarations such as "int (*foo[5])()". It can also translate the C into the pseudo- English. And it handles typecasts, too. Plus C++. And in this version it has command line editing and history with the GNU readline library.

The idea is you can easily search for keywords in the code, and jump to the file and line where a match is found. Used with ctags(1), this can really help with jumping around and following code. Some features include a human-readable output, coloring, bolding (and alternate bolding), and just sheer convenience for a programmer. cgvg uses the Perl internal find and does it's own searching, rather than being a wrapper for UNIX find(1) and grep(1). There is a ~/.cgvgrc file for per-user configuration, and some nice features like coloring, and multiple log files.

A 'special purpose/mini' distribution. From LWN Distribution List http://www.tldp.org/LDP/Linux-Dictionary/html/index.html challenge (challenge-response) A method to authenticate users that avoids sending passwords over the network. It goes something like this (though the details among various programs are different). the client requests access the server sends back random data the client then encrypts/hashes the data using the password the server checks the result In this manner, the client proves it knows the correct password without ever sending it across the wire. Key point: In most cases the user is prompted for the password, which the client then stores in memory. In the use of smart cards, however, the system may give the user the challenge string, which the user then types into the smart card. The smart card then produces a response, which the user must type back into the system. In this way, the user validates that they have the smart card. Key point: Challenge-response systems are thought to be more secure because the challenge/response is different every time. This guards against replay attacks as well as making cracking more difficult.

It is useful for ensuring a file has been transferred correctly. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html checksum A technique for detecting if data inadvertently changes during transmission. The sender simply divides all the data up into two-character numbers, then adds all the numbers together. The receiver makes the same calculation, and checks the calculated checksum with the transmitted checksum. If they don't match, then the receiver knows the data was corrupted in transit. Key point: Checksums are not secure against intentional changes by hackers. For that, you need a cryptographic hash. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Checksum An acronym for SUMmation CHECK. In data communications, an error-checking technique in which the number of bits in a unit of data is summed, transmitted along with the data, and checked by the receiving computer. If the sum differs, an error probably occurred in transmission and the transmission is repeated. A commonly used personal computer communications protocol called XMODEM uses the checksum technique. In some virus scanning and file integrity software checksums are calculted for every file in a directory and the results are stoed in the directory. When the program is scanningm it compares the checksum information stored in the directory with the current checksum for each scanned file. A difference in the sum may indicate that the file has been infected by a virus that doesn't leave a recognised signature.

A cipher transforms the original data/message into pseudo-random data/message of the same length. In order to decipher the message, a reverse transformation must be applied. Key point: A block cipher is one that encrypts a block of data at a time. For example, DES uses a block size of 64-bits. Each input block must correspond to exactly one output block (like a codebook). A block-cipher suffers from the fact the same data repeated in a message would be encoded in the same way. Consider a block size of 8-bit encrypting English text; you could therefore figure out all the letter 'e's in the cipher text because they are the most common letter used. Therefore, block-ciphers are often used in a chaining mode such that the same pattern will indeed be decrypted differently. Key point: A stream cipher is essentially a chained block cipher with a block size of 1 (either 1-bit or 1-byte). It generates a keystream against which it XORs the plaintext, operating much like a one-time pad, though less secure in theory but more secure in practice. Example: Some popular ciphers are: DES The original widely-used computer-based encryption cipher that spawned the industry, but easily crackable today. triple DES A more secure form of DES whereby data is simply encrypted three different times. RC4 One of the most widely used ciphers today because of its prevalent use within web browsers and SSL. RC2 A cipher similar to RC4. IDEA Gained popularity because it was used as the default cipher for PGP. Blowfish Popular cipher because of its open source and non-patented status. CAST-128 Alternate cipher in PGP. Skipjack Controversal cipher designed for the Clipper chip, a government program to encourage key recovery for law enforcement. GOST 28147 Russian standard with 256-bit key. AES The new American standard for replacing DES.

CMake was developed by Kitware as part of the NLM Insight Segmentation and Registration Toolkit project. The ASCI VIEWS project also provided support in the context of their parallel computation environment. Other sponsors include the Insight, VTK, and VXL open source software communities.

This allows one to combine the maintainability of a generic parameterized source code with the speed of programs optimized for specific problem instances.

From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Compiled Language A language that requires a compiler program to turn programming source code into an executable machine-language binary program. After compiling once, the program can continue to be run from its binary form without compiling again. Compiled languages/programs tend to be faster than interpreted or p-code languages, but require compilers (which can be expensive), and are often more difficult to program in than interpreted and p-code languages. Examples of compiled languages are C and C++, COBOL, and FORTRAN. From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html compiler A computer program that translates high-level programs, called source files, into low-level programs, called object files. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Compiler A program that reads the statements written in a human-readable programming language, such as Pacal or Modula-2, and translates the statements into a machine-readable executable program. Compiled programs run significantly faster than interpreted ones because the program interacts directly with the microprocessor and doesn't need to share memory space with the interpreter. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html compiler In programming, a compiler takes human readable source code and converts it into the binary code that the computer can understand. Key point: A compiler is a form of lossy compression and one-way encryption. All the information meaningful to humans is removed from the code leaving only the information necessary for the computer. This means that humans can no longer easily read the resulting program directly. Because of the "one-way" nature of the operation, programs cannot be used to recover the existing source code. This effect is different in various languages. C++ is the worst language in terms of decompilation; Java is the best. Most Java applets can be decompiled back to some semblance of their previous form. This has led to a market for programs that further obfuscate Java binaries in an effort to hide the original source code. Some compilers do leave human-readable symbols behind for debugging purposes. They won't reveal the original source, but can still be useful for reverse engineering They can be "stripped" from the binary. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html compilercache a caching wrapper around compilers to speed up compilations Compilercache is a wrapper around your C and C++ compilers. Each time you compile something, the wrapper puts the result of the compilation into a cache. And once you compile the same thing again, the result will be picked from the cache instead of being recompiled. Care is taken to ensure that compilation with and without compilercache always results in identical object files.

From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Compress To make a file smaller by applying a compression algorithm, usually for the purpose of conserving space or speeding up file transfers. This can also refer to the Unix command to compress a file which appends '.Z' to the filename, or to the free GNU enhanced version, gzip.

From Glossary of Distance Education and Internet Terminology http://www.tldp.org/LDP/Linux-Dictionary/html/index.html compression Since encrypted data is essentially random, you cannot compress it. This defeats networking standards designed to automatically encrypt traffic (such as dial-up modems). Therefore, data must be compressed before it is encrypted. For this reason, compression is becoming an automatic feature to most encryption products. The most often used compression standard is gzip and its compression library zlib. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html compression Special encoding of data to reduce byte size; useful in storing and archiving large (or multiple) files or for transmission of data over a network. From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Compression The compacting of files to save storage space and reduce transfer time. Compression uses algorithms such as Lempel-Ziv, LZW and Huffman coding. From Linux Guide @FirstLinux http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Compression The reduction of a file's size by means of a compression program. The two types of compression are loassless compression and lossy compression. In lossless compression, the compression process allows for subsequent decompression of the data with no loss of the original data. Lossless compression is used for program and dat files. Lossy compression, in which the compression processes remove some of the data in a way that is not obvious to a person using te data. Lossy compression is used for sounds, graphics, animations, and videos. Many modems offer on-the-fly compression, and often use the MNP5 or V.42bis protocols. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html compression methods There are two types: With lossless compression none of the original information is lost. Generally such compression can reduce the file size by about 50%. A popular lossless compression for graphics files is .tga (Targa) or for data .gz and .zip. The other compression method is lossy compression where some of the original information is lost. Lossy compression methods can reduce the file size often by 300% but are unsuitable in many situations. They are particularly useful for the compression of graphic files with JPEG compression being the most popular, especially as they help to reduce bandwidth.

The object of the game is twofold. The short-range goal is to accumulate "kills" by shooting down enemy players. You get one kill point for each enemy ship shot down, plus some extra if the enemy had kills too. The major weapon used to shoot down ships is the photon torpedo. The long-range goal is to conquer the universe for your team by taking every planet. You take planets by killing off the enemy's armies via bombardment, and then beaming your team's armies down. When all the planets have been taken, the game ends, a new game begins, and the player who actually took the last planet gets his/her name up in lights. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cons A Perl replacement for Make Excerpted from the README file: Cons is a system for constructing, primarily, software, but is quite different from previous software construction systems. Cons was designed from the ground up to deal easily with the construction of software spread over multiple source directories. Cons makes it easy to create build scripts that are simple, understandable and maintainable. Cons ensures that complex software is easily and accurately reproducible. Cons uses a number of techniques to accomplish all of this. Construction scripts are just Perl scripts, making them both easy to comprehend and very flexible. Global scoping of variables is replaced with an import/export mechanism for sharing information between scripts, significantly improving the readability and maintainability of each script. Construction environments are introduced: these are Perl objects that capture the information required for controlling the build process. Multiple environments are used when different semantics are required for generating products in the build tree. Cons implements automatic dependency analysis and uses this to globally sequence the entire build. Variant builds are easily produced from a single source tree. Intelligent build subsetting is possible, when working on localized changes. Overrides can be setup to easily override build instructions without modifying any scripts. MD5 cryptographic signatures are associated with derived files, and are used to accurately determine whether a given file needs to be rebuilt.

From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Cookie The most common meaning of "Cookie" on the Internet refers to a piece of information sent by a Web Server to a Web Browser that the Browser software is expected to save and to send back to the Server whenever the browser makes additional requests from the Server. Depending on the type of Cookie used, and the Browsers' settings, the Browser may accept or not accept the Cookie, and may save the Cookie for either a short time or a long time. Cookies might contain information such as login or registration information, online "shopping cart" information, user preferences, etc. When a Server receives a request from a Browser that includes a Cookie, the Server is able to use the information stored in the Cookie. For example, the Server might customize what is sent back to the user, or keep a log of particular users' requests. Cookies are usually set to expire after a predetermined amount of time and are usually saved in memory until the Browser software is closed down, at which time they may be saved to disk if their "expire time" has not been reached. Cookies do not read your hard drive and send your life story to the CIA, but they can be used to gather more information about a user than would be possible without them.

The operating system kills the program and creates a core file that programmers can use to figure out what went wrong. It contains a detailed description of the state that the program was in when it died. If would like to determine what program a core file came from, use the file command, like this: $ file core That will tell you the name of the program that produced the core dump. You may want to write the maintainer(s) of the program, telling them that their program dumped core. To Enable or Disable Core Dumps you must use the ulimit command in bash, the limit command in tcsh, or the rlimit command in ksh. See the appropriate manual page for details. This setting affects all programs run from the shell (directly or indirectly), not the whole system. If you wish to enable or disable core dumping for all processes by default, you can change the default setting in /usr/include/linux/sched.h. Refer to definition of INIT_TASK, and look also in /usr/include/linux/resource.h. PAM support optimizes the system's environment, including the amount of memory a user is allowed. In some distributions this parameter is configurable in the /etc/security/limits.conf file. From Linux Administrator's Security Guide. http://www.tldp.org/LDP/Linux-Dictionary/html/index.html core n.

When coping over a previous copy, the key features will allow coping only of new or non existing files in the backup. This results in saving time and less load on the drive. Built into the same feature of copying new files only, is a file removal procedure. If a file is removed from the source path, the same file will be removed when the next backup is performed. This provides a backup that is exactly the same as the source without filling up the drive. As an added option, all files that will be overwritten or deleted when doing a copy over a previous backup, have the opportunity to be stored in a trash bin. You can leave this trash bin to grow and grow just in case you need a backup of your backup. When you start running out of disk space you will need to remove or clean up the trash bin.

Archives are files which contain a collection of other files plus information about them, such as their file name, owner, timestamps, and access permissions. The archive can be another file on the disk, a magnetic tape, or a pipe. GNU cpio supports the following archive formats: binary,old ASCII, new ASCII, crc, HPUX binary, HPUX old ASCII, old tar and POSIX.1tar. By default, cpio creates binary format archives, so that they are compatible with older cpio programs. When it is extracting files from archives, cpio automatically recognizes which kind of archive it is readingand can read archives created on machines with a different byte-order.

See crackz for more about copy protection. History: When the UNIX operating system was first developed, passwords were stored in the file /etc/passwd. This file was made readable by everyone, but the passwords were encrypted so that a user could not figure out who a person's password was. The passwords were encrypted in such a manner that you could test a password to see if it was valid, but you really couldn't decrypt the entry. (Note: not even administrators are able to figure out user's passwords; they can change them, but not decrypt them). However, a program called "crack" was developed that would simply test all the words in the dictionary against the passwords in /etc/passwd. This would find all user accounts whose passwords where chosen from the dictionary. Typical dictionaries also included people's names since a common practice is to choose a spouse's or child's name. Contrast: A "crack" program is one that takes existing encrypted passwords and attempts to find some that are "weak" and easily discovered. However, it is not a "password guessing" program that tries to login with many passwords, that is known as a grind Key point: The sources of encrypted passwords typically include the following: /etc/passwd from a UNIX system SAM or SAM._ from a Windows NT system <username>.pwl from a Windows 95/98 system sniffed challenge hashes from the network Key point: The "crack" program is a useful tool for system administrators. By running the program on their own systems, they can quickly find users who have chosen weak passwords. In other words, it is a policy enforcement tool. Tools: on UNIX, the most commonly used program is called simply "crack". On Windows, a popular program is called "l0phtCrack" from http://www.l0pht.com/.

CrackLib performs several tests on passwords: it tries to generate words from a username and gecos entry and checks those words against the password; it checksfor simplistic patterns in passwords; and it checks for the password in a dictionary. CrackLib is actually a library containing a particular C function which is used to check the password, as well as other Cfunctions. CrackLib is not a replacement for a passwd program; it must be used in conjunction with an existing passwd program.

Adding a new command is a simple affair, and a quick recompile adds it to the command menu. o The intent is to make the tool independent of Linux version dependencies, building in recognition of major kernel code changes so as to adapt to new kernel versions, while maintaining backwards compatibility.

From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Cron A Linux daemon that executes specified tasks at a designated time or interval (can be daily, weekly, etc....). From I-gloss http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cron management of regular background processing cron is a background process (`daemon') that runs programs at regular intervals (for example, every minute, day, week or month); which processes are run and at what times are specified in the `crontab'. Users may also install crontabs so that processes are run on their behalf, though this feature can be disabled or restricted to particular users. Output from the commands is usually mailed to the system administrator (or to the user in question); you should probably install a mail system as well so that you can receive these messages. This cron package is configured by default to do various standard system maintenance tasks, such as ensuring that logfiles do not grow endlessly and overflow the disk. The lockfile-progs package is only a "Suggests" because of the poor way that dselect handles "Recomments", but I do strongly suggest that you install it; it prevents /etc/cron.daily/standard from running multiple times if something gets jammed. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cron On UNIX, the cron daemon automated background tasks (such as backups or rotating the logs). It is really the simplest of programs; it reads instructions from a file and executes the appropriate programs at the scheduled time. Key point: When the machine is compromised, intruders will often put backdoor jobs into the crontab. When the victim tries to clean up his/her machine, the jobs in the crontab will run giving the intruder control again. This sort of thing happened in the famous attack against the New York Times; they kept cleaning up the machine, but cron kept giving control back to the intruder. Typically, these jobs would run during the wee hours of the morning when nobody is looking. From Hacking-Lexicon http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cron-apt Automatic update of packages using apt This package contains a tool that is run by a cron job at regular intervals. By default it just updates the package list and download new packages without installing. You can instruct it to run anything that you can do with apt-get. It also sends mail (configurable) to the system administrator on errors. Observe that this tool is a security risk, so you should not set it to do more than necessary (automatic upgrade of all packages is NOT recommended). From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html cronolog Logfile rotator for web servers A simple program that reads log messages from its input and writes them to a set of output files, the names of which are constructed using template and the current date and time. The template uses the same format specifiers as the Unix date command (which are the same as the standard C strftime library function). It intended to be used in conjunction with a Web server, such as Apache, to split the access log into daily or monthly logs: TransferLog "|/usr/sbin/cronolog /var/log/apache/%Y/access.%Y.%m.%d.log" A cronosplit script is also included, to convert existing traditionally-rotated logs into this rotation format.

The modules act as a filter, taking a set of credentials as input and writing a set of facts as output if those credentials are valid. Optional input is given to the module through environment variables. Some of the ideas for CVM came from experience with PAM (pluggable authentication modules), the checkpassword interface used by qmail-pop3d, and the "authmod" interface used by Courier IMAP and POP3. This framework places fewer restrictions on the invoking client than checkpassword does, and is much simpler to implement on both sides than PAM and the authmod framework.

From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html CVS A source code control system is a MUST to manage the changes occurring to a software project during development. Developers need a complete history of changes to backtrack to previous versions in case of any problems. Since source code is the most vital component of any software project and software development takes a huge amount of time and money, it is very important to spend some time in safe-guarding the source code by using source code control systems like CVS and RCS. CVS (Concurrent Version Control System) is a powerful tool which allows concurrent development of software by multiple users. It uses RCS underneath and has an application layer interface as a wrapper on top of RCS. CVS can record the history of your files (usually, but not always, source code). CVS only stores the differences between versions, instead of every version of every file you've created. CVS also keeps a log of who, when and why changes occurred, among other aspects. CVS is very helpful for managing releases and controlling the concurrent editing of source files among multiple authors. Instead of providing version control for a collection of files in a single directory, CVS provides version control for a hierarchical collection of directories consisting of revision controlled files. These directories and files can then be combined to form a software release. CVS can be used for storing "C", "C++", Java, Perl, HTML and other files. HISTORY of CVS: CVS is a very highly sophisticated and complex system. It is the "State of the Art" technology and is so called "software miracle". The CVS software is a very advanced and capable system developed over a very long period of time. And it took several years to mature!! It took about 20 to 30 years of research to develop CVS algorithms and later it was coded into a software. And even today, it is still evolving!! CVS algorithms actually started in Universities several decades ago and CVS implementation started out as a bunch of shell scripts written by Dick Grune, who posted it to the newsgroup comp.sources.unix in the volume 6 release of December, 1986. While no actual code from these shell scripts is present in the current version of CVS much of the CVS conflict resolution algorithms come from them. In April, 1989, Brian Berliner designed and coded CVS. Jeff Polk later helped Brian with the design of the CVS module and vendor branch support. And today each and every major software development project in the world is written using CVS as the safe repository. As good old software hats say - "You are in very safe hands, if you are using CVS !!!"

Unlike the simpler systems, CVS does not just operate on one file at a time or one directory at a time, but operates on hierarchical collections of directories consisting of version controlled files. CVS helps to manage releases and to control the concurrent editing of source files among multiple authors.

From Redhat-9-Glossary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Cylinder In hard and floppy disk drives, a unit of storage consisting of the set of tracks that occupy the same position on opposite sides of the platter. On a double-sided disk, a cylinder includes track 1 on the top of one another, a cylinder consists of track 1 on both sides of all the disks. From QUECID http://www.tldp.org/LDP/Linux-Dictionary/html/index.html Cylinders, heads, and sectors The physical drive itself usually comprises several actual disks of which both sides are used. The sides are labelled 0, 1, 2, 3, and so on, and are also called heads because one magnetic head per side does the actual reading and writing. Each side/head has tracks, and each track is divided into segments called sectors. Each sector typically holds 512 bytes. The total amount of space on the drive in bytes is therefore: 512 x (sectors-per-track) x (tracks-per-side) x (number-of-sides) A single track and all the tracks of the same diameter (on all the sides) are called a cylinder. Disks are normally talked about in terms of ``cylinders and sectors'' instead of ``sides, tracks, and sectors.'' Partitions are (usually) divided along cylinder boundaries. Hence, disks do not have arbitrarily sized partitions; rather, the size of the partition is usually a multiple of the amount of data held in a single cylinder. Partitions therefore have a definite inner and outer diameter.
