vanilla

adj. [from the default flavor of ice cream in the U.S.] Ordinary flavor, standard. When used of food, very often does not mean that the food is flavored with vanilla extract! For example, `vanilla wonton soup' means ordinary wonton soup, as opposed to hot-and-sour wonton soup. Applied to hardware and software, as in "Vanilla Version 7 Unix can't run on a vanilla 11/34." Also used to orthogonalize chip nomenclature; for instance, a 74V00 means what TI calls a 7400, as distinct from a 74LS00, etc. This word differs from canonical in that the latter means `default', whereas vanilla simply means `ordinary'. For example, when hackers go on a great-wall, hot-and-sour soup is the canonical soup to get (because that is what most of them usually order) even though it isn't the vanilla (wonton) soup.

vat

LBNL audio conferencing tool over the internet. The LBNL audio tool, vat, is a real-time, multi-party, multimedia application for audio conferencing over the Internet. Vat is based on the Draft Internet Standard Real-time Transport Protocol (RTP) developed by the IETF Audio/Video Transport working group. RTP is an application-level protocol implemented entirely within vat -- you need no special system enhancements to run RTP. Although vat can be run point-to-point using standard unicast IP addresses, it is primarily intended as a multi-party conferencing application. To make use of the conferencing capabilities, your system must support IP Multicast, and ideally, your network should be connected to the IP Multicast Backbone (MBone). Vat provides only the audio portion of a multimedia conference; video, whiteboard, and session control tools are implemented as separate applications. Our video tool is called vic and our whiteboard tool wb, UCL developed the session directory tool sdr Other related applications include ISI's Multimedia Conference Control, mmcc, the Xerox PARC Network Video tool, nv and the INRIA Video-conferencing System, ivs. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

VAX

/vaks/ n. 1. [from Virtual Address eXtension] The most successful minicomputer design in industry history, possibly excepting its immediate ancestor, the PDP-11. Between its release in 1978 and its eclipse by killer micros after about 1986, the VAX was probably the hacker's favorite machine of them all, esp. after the 1982 release of 4.2 BSD Unix (see BSD). Esp. noted for its large, assembler-programmer-friendly instruction set -- an asset that became a liability after the RISC revolution. 2. A major brand of vacuum cleaner in Britain. Cited here because its sales pitch, "Nothing sucks like a VAX!" became a sort of battle-cry of RISC partisans. It is even sometimes claimed that DEC actually entered a cross-licensing deal with the vacuum-Vax people that allowed them to market VAX computers in the U.K. in return for not challenging the vacuum cleaner trademark in the U.S. A rival brand actually pioneered the slogan: its original form was "Nothing sucks like Electrolux". It has apparently become a classic example (used in advertising textbooks) of the perils of not knowing the local idiom. But in 1996, the press manager of Electrolux AB, while confirming that the company used this slogan in the late 1960s, also tells us that their marketing people were fully aware of the possible double entendre and intended it to gain attention. And gain attention it did - the VAX-vacuum-cleaner people thought the slogan a sufficiently good idea to copy it. Several British hackers report that VAX's promotions used it in 1986-1987, and we have one report from a New Zealander that the infamous slogan surfaced there in TV ads for the product in 1992.

vdiff

/vee'dif/ v.,n. Visual diff. The operation of finding differences between two files by eyeball search. The term `optical diff' has also been reported, and is sometimes more specifically used for the act of superimposing two nearly identical printouts on one another and holding them up to a light to spot differences. Though this method is poor for detecting omissions in the `rear' file, it can also be used with printouts of graphics, a claim few if any diff programs can make. See diff. An interesting variant of the vdiff technique usable by anyone who has sufficient control over the parallax of their eyeballs (e.g. those who can easily view random-dot stereograms), is to hold up two paper printouts and go cross-eyed to superimpose them. This invokes deep, fast, built-in image comparison wetware (the same machinery responsible for depth perception) and differences stand out almost immediately. This technique is good for finding edits in graphical images, or for comparing an image with a compressed version to spot artifacts.<p> From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

Version 7 alt. V7

/vee' se'vn/ n. The first widely distributed version of Unix, released unsupported by Bell Labs in 1978. The term is used adjectivally to describe Unix features and programs that date from that release, and are thus guaranteed to be present and portable in all Unix versions (this was the standard gauge of portability before the POSIX and IEEE 1003 standards). Note that this usage does not derive from the release being the "seventh version of Unix"; research Unix at Bell Labs has traditionally been numbered according to the edition of the associated documentation. Indeed, only the widely-distributed Sixth and Seventh Editions are widely known as V[67]; the OS that might today be known as `V10' is instead known in full as "Tenth Edition Research Unix" or just "Tenth Edition" for short. For this reason, "V7" is often read by cognoscenti as "Seventh Edition". See BSD, USG Unix, Unix. Some old-timers impatient with commercialization and kernel bloat still maintain that V7 was the Last True Unix. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

vi

/V-I/, not /vi:/ and never /siks/ n. [from `Visual Interface'] A screen editor crufted together by Bill Joy for an early BSD release. Became the de facto standard Unix editor and a nearly undisputed hacker favorite outside of MIT until the rise of EMACS after about 1984. Tends to frustrate new users no end, as it will neither take commands while expecting input text nor vice versa, and the default setup on older versions provides no indication of which mode the editor is in (years ago, a correspondent reported that he has often heard the editor's name pronounced /vi:l/; there is now a vi clone named `vile'). Nevertheless vi (and variants such as vim and elvis) is still widely used (about half the respondents in a 1991 Usenet poll preferred it), and even EMACS fans often resort to it as a mail editor and for small editing jobs (mainly because it starts up faster than the bulkier versions of EMACS). See holy wars. From Jargon Dictionary http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

vi

On UNIX, the vi program is a small text editor that can be run from the command-line. It can even be run in ed/ex mode that runs in line-mode rather than full-screen mode. Since vi is included on every UNIX system, this is the one program that all hackers learn to use. (More advanced editors like emacs may not be installed on a system that a hacker breaks into, leaving them out of luck if they don't know vi).

VIM

Vim stands for 'Vi Improved'. Vi is one of the most popular and powerful editors in the Unix world. Vi is an abbreviation for "Visual" editor. One of the first editors was a line editor called 'ed' (and 'ex'). The Visual editor like Vi was a vast improvement over line editors like 'ed' (or 'ex'). The editors 'ed' and 'ex' are still available on Linux: see 'man ed' and 'man ex'. A good editor improves programmer productivity. Vim supports color syntax highlighting of program code and also emphasises text using different fonts like normal, bold or italics. A color editor like Vim can improve the productivity of programmers by 2 to 3 times!! Programmers can read the code much more rapidly as the code syntax is colored and highlighted.

Virus

A chunk of computer programming code that makes copies of itself without any concious human intervention. Some viruses do more than simply replicate themselves, they might display messages, install other software or files, delete software of files, etc. A virus requires the presence of some other program to replicate itself. Typically viruses spread by attaching themselves to programs and in some cases files, for example the file formats for Microsoft word processor and spreadsheet programs allow the inclusion of programs called "macros" which can in some cases be a breeding ground for viruses. From Matisse http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

virus

A virus is a program (or a fragment of code) that replicates by attaching a copy of itself to other programs. For a virus to be activated, the software it infects must first be run. Analogy: A biological virus is not a "living" thing. Instead, it is simply a strand of DNA. When it enters a living cell, it takes control of the cell forcing it to generate duplicate copies of the original DNA strand. In much the same way, a computer virus hijacks the computer forcing it to generate duplicate copies of the original virus. Computer viruses are so common because humans do not practice sufficient cyber-hygiene when exchanging files. Key point: An "anti-virus" programs scans the disks on your system hunting down those files that have signatures indicative of infected files. Since file-scanning technology is generic, most anti-virus programs also scan for other hostile content, such as trojans. Contrast: The popular use of the word "virus" means any form of malware. For example, in the movie Office Space, the protagonists write what is called a "virus" that runs in the banking mainframe to steal round-off errors. In contrast, the technical definition limits itself to just those forms of contagious malware that spreads by infecting other programs. Key point: Viruses have a life cycle from the point they are originally created, distributed, found by anti-virus programs, then eradicated. They also mutate as script kiddies take viruses, make small alteration that avoids current virus scanners, and redistribute the viruses. Example: boot sector Historically, the most popular kind of virus, though becoming less popular as floppies are used less often. E.g. Form Virus macro virus Data files cannot contain viruses -- except when they also include scripting "macros". Currently the most popular kind of virus. Most macro viruses are written in VisualBasic, a programming language included as part of Microsoft Office products (Word, Excel). E.g. Marker Virus file infector The traditional definition of a virus: an executable file contains a virus imbedded within. When run, it attaches the virus to other executables on the system. multi-part Uses more than one of the techniques above. toolkits Increasingly, viruses are created via toolkits designed for the purpose of creating viruses that evade anti-virus programs. polymorphic This type of virus automatically changes its form in order to evade anti-virus programs. A common technique is to XOR its code with changing patterns. Culture: Viruses are rarely written by a single human being. Instead, they are often written by groups. Each virus is usually built upon work done by other virus writers. This means that a virus is usually related to other viruses. Computer viruses mutate and exchange genetic material much like biological systems. What we classify as the "author" of a virus is usually somebody who made one small mutation that made a virus especially virulent.

virus

n. [from the obvious analogy with biological viruses, via SF] A cracker program that searches out other programs and `infects' them by embedding a copy of itself in them, so that they become Trojan horses. When these programs are executed, the embedded virus is executed too, thus propagating the `infection'. This normally happens invisibly to the user. Unlike a worm, a virus cannot infect other computers without assistance. It is propagated by vectors such as humans trading programs with their friends (see SEX). The virus may do nothing but propagate itself and then allow the program to run normally. Usually, however, after propagating silently for a while, it starts doing things like writing cute messages on the terminal or playing strange tricks with the display (some viruses include nice display hacks). Many nasty viruses, written by particularly perversely minded crackers, do irreversible damage, like nuking all the user's files. In the 1990s, viruses became a serious problem, especially among Windows users; the lack of security on these machines enables viruses to spread easily, even infecting the operating system (Unix machines, by contrast, are immune to such attacks). The production of special anti-virus software has become an industry, and a number of exaggerated media reports have caused outbreaks of near hysteria among users; many lusers tend to blame everything that doesn't work as they had expected on virus attacks. Accordingly, this sense of `virus' has passed not only into techspeak but into also popular usage (where it is often incorrectly used to denote a worm or even a Trojan horse).

vlan

User mode programs to enable VLANs on your ethernet devices This package contains the user mode programs you need to add and remove VLAN devices from your ethernet devices. A typical application for a VLAN enabled box is a single wire firewall, router or load balancer. You need a VLAN kernel for this. Kernel versions < 2.4.14 need to be patched.

VLAN

Virtual Local Area Network (LAN, IEEE 802.1q) From VERA http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

VLAN (Virtual Local Area Network, IEEE 802.1q)

A VLAN allows multiple virtual LANs to coexist on the same physical LAN (switched). This means that two machines attached to the same switch cannot send Ethernet frames to each other even though they pass over the same wires. If they need to communicate, then a router must be placed between the two VLANs to forward packets, just as if the two LANs were physically isolated. The only difference is that the router in question may contain only a single Ethernet NIC that is part of both VLANs (a one-armed router). The frames are "tagged" with an 802.1q prefix as they enter the network, which the Ethernet switches will use to separate traffic. Key point: Sometimes people want to put a firewall between VLANs, putting their DMZ on one VLAN on the rest of their company on another. This is an extraordinarily bad thing to do. VLANs are designed primarily to segment broadcast domains and improve performance and manageability. They are not hardened against security breaches. For example, Bay switches will forward packets incorrectly if the MAC address is known by the hacker. Cisco ATM switches have been known to leak frames onto incorrect VLANs when overloaded. Key point: Most cable-modem and DSL connectivity is provided via VLANs over an ATM infrastructure. All the security concerns expressed above for VLANs applies to these technologies as well.

A mail user agent for Emacs VM (View Mail) is an Emacs subsystem that allows UNIX mail to be read and disposed of within Emacs. Commands exist to do the normal things expected of a mail user agent, such as generating replies, saving messages to folders, deleting messages and so on. There are other more advanced commands that do tasks like bursting and creating digests, message forwarding, and organizing message presentation according to various criteria. With smtpmail in modern emacsen, you do not need a MTA locally in order to use VM. VM 6.x versions have problems with the library tm-vm from the Tiny Mime (TM) package, since that version was written for VM 5.X. Indeed, the problems seems to exist with semi as well.

vmnet

A simple virtual networking program This program has been written to implement virtual networking support for the Hercules S/390 simulator, but it is intentionally generic in its functionality, so any other virtual machine simulator/emulator program could potentially use it. The function is quite simple: - The virtual machine simulator program starts VMnet and talks the SLIP protocol with it over stdin/out. - VMnet sets up a SLIP connection on the host system, talking over a pseudo-tty to the VMnet program. - Once things have been set up, VMnet simply copies the data streams between stdin/out and the SLIP psuedo-tty in both directions. Thus, the virtual machine has a direct SLIP connection with the host, without needing to worry about root privileges, pseudo-ttys, access rights, etc. From Debian 3.0r0 APT http://www.tldp.org/LDP/Linux-Dictionary/html/index.html

VoIP

VoIP stands for 'V'oice 'o'ver 'I'nternet 'P'rotocol. As the term says VoIP tries to let go voice (mainly human) through IP packets and, in definitive through Internet. VoIP can use accelerating hardware to achieve this purpose and can also be used in a PC environment. Many years ago we discovered that sending a signal to a remote destination could have be done also in a digital fashion: before sending it we have to digitalize it with an ADC (analog to digital converter), transmit it, and at the end transform it again in analog format with DAC (digital to analog converter) to use it. VoIP works like that, digitalizing voice in data packets, sending them and reconverting them in voice at destination. Digital format can be better controlled: we can compress it, route it, convert it to a new better format, and so on; also we saw that digital signal is more noise tolerant than the analog one (see GSM vs TACS). TCP/IP networks are made of IP packets containing a header (to control communication) and a payload to transport data: VoIP use it to go across the network and come to destination. Voice (source) - - ADC - - - - Internet - - - DAC - - Voice (dest) What is the advantages using VoIP rather PSTN? When you are using PSTN line, you typically pay for time used to a PSTN line manager company: more time you stay at phone and more you'll pay. In addition you couldn't talk with other that one person at a time. In opposite with VoIP mechanism you can talk all the time with every person you want (the needed is that other person is also connected to Internet at the same time), as far as you want (money independent) and, in addition, you can talk with many people at the same time. If you're still not persuaded you can consider that, at the same time, you can exchange data with people are you talking with, sending images, graphs and videos. Then, why everybody doesn't use it yet? Unfortunately we have to report some problem with the integration between VoIP architecture and Internet. As you can easy imagine, voice data communication must be a real time stream (you couldn't speak, wait for many seconds, then hear other side answering): this is in contrast with the Internet heterogeneous architecture that can be made of many routers (machines that route packets), about 20-30 or more and can have a very high round trip time (RTT), so we need to modify something to get it properly working.From VoIP HOWTO http://www.tldp.org/LDP/Linux-Dictionary/html/index.html
