M

MAC (Message Authentication Code)

A specific type of message digest where the secret key is included as part of the fingerprint. Whereas a normal digest consists of a hash(data), the MAC consists of a hash(key + data). Contrast: The most common form is actually HMAC (hash MAC) that uses the algorithm hash(key + hash(key + data)). From Hacking-Lexicon

MAC address

Every piece of Ethernet hardware has a unique number assigned to it called it's MAC address. Remember that Ethernet is used locally to connect you to the Internet, and you share the local network with many other people. The MAC address is used by your local Internet router in order to direct your traffic to you rather than somebody else in your local area. Key point: The MAC address is 6-bytes long, and must be unique. In order to guarantee uniqueness, equipment vendors are assigned a unique 3-byte prefix, and they then assign their own 3-byte suffix. Thus, the first 3-bytes of a MAC address identifies what kind of hardware you have (3Com, Cisco, Intel, etc.). Key point: The uniqueness property of MAC addresses has interesting implications. It was an important clue in tracking down David Smith (the Melissa author). From Hacking-Lexicon

MAKEDEV

This package contains the MAKEDEV script, which makes it easier to createand maintain the files in the /dev directory. /dev directory files correspond to a particular device supported by Linux (serial or printer ports, scanners, sound cards, tape drives, CD-ROM drives, hard drives, etc.) and interface with the drivers in the kernel. You should install the MAKEDEV package because the MAKEDEV utility makes it easy to manage the /dev directory device files. From Redhat 8.0 RPM

MCC Interim Linux

MCC Interim Linux was started by the Manchester Computing Centre in February of 1992, after they made Linux availible on their FTP site in November of 1991. The distribution was one of the first to use a combined boot/root disk. Several distributions were based off of MCC Interim Linux, including TAMU, MJ, and SLS (which later morphed into Slackware Linux, a distribution that's still alive today). Distribution development is not all that active. From LWN Distribution List

MD4 (Message Digest #4)

An older hash algorithms that used to be popular. It is important today only for historical significance because it has been discovered to be "broken". From Hacking-Lexicon

MD5 (Message Digest #5, 1.2.840.113549.2.5, RFC 1321)

MD5 is one of the most popular hash algorithms. It processes an input file or message into a "unique" 128-bit fingerprint. This fingerprint is believed to be "unique"; while it is theoretically possible that two inputs could hash to the same fingerprint, it is nearly statistically impossible. Contrast: Compared to other hash algorithms, MD5 is extremely popular. It is the most popular hashing algorithm, used in SSL, PGP, HTTP authentication, Tripwire, and many other places. MD5 is one of the faster hash algorithms. However, a theoretical weakness has been found such that an attacker may be able to create two separate messages that hash to the same value. Therefore, most use of MD5 is simply for backwards compatibility. History: MD5 was written by Ron Rivest as an enhanced version of the earlier MD4. MD4 is part of many standards, but is considered completely broken by today's standards (and MD5 itself is now considere to have some weaknesses). See also: integrity From Hacking-Lexicon

MIME

(Multipurpose Internet Mail Extensions) The protocol for attaching non-text files to email messages (graphics, spreadsheets, formatted text documents, sound files, Quicktime, multimedia files, etc.) MIME is utilised by some email packages & is universally used by Web Servers to identify the files they are sending to Web Clients. From Faculty-of-Education

MIME (Multipurpose Internet Mail Extensions)

Originally a standard for defining the types of files attached to standard Internet mail messages. The MIME standard has come to be used in many situations where one cmputer programs needs to communicate with another program about what kind of file is being sent. For example, HTML files have a MIME-type of text/html, JPEG files are image/jpeg, etc. From Matisse

MIME encapsulation

Most graphical mail readers have the ability to attach files to mail messages and read these attachments. The way they do this is not with uuencode but in a special format known as MIME encapsulation. MIME (Multipurpose Internet Mail Extensions) is a way of representing multiple files inside a single mail message. The way binary data is handled is similar to uuencode, but in a format known as base64. Each MIME attachment to a mail message has a particular type, known as the MIME type. MIME types merely classify the attached file as an image, an audio clip, a formatted document, or some other type of data. The MIME type is a text tag with the format <major>/<minor>. The major part is called the major MIME type and the minor part is called the minor MIME type. Available major types match all the kinds of files that you would expect to exist. They are usually one of application, audio, image, message, text, or video. The application type means a file format specific to a particular utility. The minor MIME types run into the hundreds. A long list of MIME types can be found in /etc/mime.types. If needed, some useful command-line utilities in the same vein as uuencode can create and extract MIME messages. These are mpack, munpack, and mmencode (or mimencode). From Rute-Users-Guide

MTA

Alongside the web, mail is the top reason for the popularity of the Internet. E-mail is an inexpensive and fast method of time-shifted messaging which, much like the Web, is actually based around sending and receiving plain text files. The protocol used is called the Simple Mail Transfer Protocol (SMTP). The server prorgams that implement SMTP to move mail from one server to another are called Mail Transfer Agents (MTAs). Once upon a time users would have to Telnet into an SMTP server and use a command line mail program like 'mutt' or 'pine' to check their mail. Now, GUI based e-mail clients like Mozilla, Kmail and Outlook allow users to check their email off of a local SMTP sever. Additional protocols like POP3 and IMAP4 are used between the SMTP server and desktop mail client to allow clients to manipulate files on, and download from, their local mail server. The programs that implement POP3 and IMAP4 are called Mail Delivery Agents (MDAs). They are generally seperate from MTAs. From Advanced Linux Pocketbook

MTBF (Mean time between failures)

Macro

A program consisting of recorded keystrokes and an application's command language that, when run within the application, executes the keystrokes and commands to accomplish a task. Macros can automate tedious and often-repeated tasks (such as saving and backing up a file to a floppy) or create special menus to speed data entry. Some programs provide a macro-recording mode in which the program records your keystrokes and then saves the recording as a macro. Others provide a built-in macro editor, where you type and edit macro commands directly to create IF/THEN/ELSE statements and DO/WHILE loops. From QUECID

Macro

A set of instructions stored in an executable form. Macros may be application specific (such as a spreadsheet or word processing macro that performs specific steps within that program) or general-purpose (for example, a keyboard macro that types in a user ID when Ctrl-U is pressed on the keyboard).

Mailing Lists

A mailing list is a special address that, when posted to, automatically sends email to a long list of other addresses. You usually subscribe to a mailing list by sending some specially formatted email or by requesting a subscription from the mailing list manager. Once you have subscribed to a list, any email you post to the list will be sent to every other subscriber, and every other subscriber's posts to the list will be sent to you. There are mostly three types of mailing lists: the majordomo type, the listserv type, and the *-request type. From Rute-Users-Guide

Maillist (or Mailing List)

A (usually automated) system that allows people to send e-mail to one address, whereupon their message is copied and sent to all of the other subscribers to the maillist. In this way, people who have many different kinds of e-mail access can participate in discussions together. From Matisse

Mainframe

A multi-user computer designed to meet the computing needs of a large organisation. Originally, the term mainframe referred to the metal cabinet that housed the central processing unit (CPU) of early computers. The term came to be used gerneally to refer to the large central computers developed in the late 1950s and 1960s to meet the accounting and information-management needs of large organisations. The largest mainframes can handle thousands of dumb terminals and use terabytes of secondary storage. See minicomputer, personal computer, and workstarion. From QUECID

Metcalfe's Law

A philosophical point of view: "The power of the network increases exponentially by the number of computers connected to it. Therefore, the every computer added to the network both uses it as a resource while adding resources in a spiral of increasing value and choice." -- Dr. Bob M. Metcalfe, inventor of Ethernet, co-founder of 3Com, editor-in-chief of InfoWorld. The idea is that the power of the Internet is not simply all the websites that you can access (linear), but the power represented by everyone else also on the Internet (exponential). For example, organizations like http://www.distributed.net/ cannot only harness lots of machines in order to tackle large problems (linear), but they also can exploit the word-of-mouth on the Internet to sign up (exponential). Similarly, consider the growth in sites like http://www.slashdot.org/ that start out as hobbyist sites, but eventually blossom into large money making ventures, tossing pre-Internet-age business philosophies on their ear. Key point: Hacker attacks grow exponentially because more and more hackers are getting online (especially from 3rd world countries) and more and more resources (businesses) are getting online. Key point: The amount of computing resources a hacker can tap into from his/her computer desktop is more than the combined might of all governments and militaries. From Hacking-Lexicon

Mirror

Generally speaking, "to mirror" is to maintain an exact copy of something. Probably the most common use of the term on the Internet refers to "mirror sites" which are web sites, or FTP sites that maintain copies of material originated at another location, usually in order to provide more widespread access to the resource. For example, one site might create a library of software, and 5 other sites might maintain mirrors of that library. From Matisse

Modula-2

A high-level programming language that extends Pascal so that the language can execute program modules independently. Developed in 1980 by computer wizard and Pascal creator Niklaus Wirth, Modula-2 supports the separate compilation of program modules and overcomes many other shortcomings of Pascal. A programer working as part of a team can write and compile the module he or she has been assigned, and then test the module extensively before integrating it with other modules. Although Modula-2 is increasingly popular as a teaching language at colleges and universities, C dominates professional software development. See modular progrmming and structured programming. From QUECID

Modular programming

A programming style that braks down program functions into modules, each of which accomplishes one function and contains all the source code and variables needed to accomplish that function. Modular programming is a solution to the problem of very large programs that are difficult to debug and maintain. By segmenting the program into modules that perform clearly defined functions, you can determine the source of program erros more easly. Object-orientated programming languages, such as SmallTalk and HyperTalk, incorporate modular programming principles. From QUECID

Modulation

The conversion of a digital signal to its analog equivalent, especially for the purposes of transmitting signals using telephone lines and modems. See demodulation. From QUECID

Moore's Law

Gordon Moore, one of the founders of Intel, remarked in the late 1960s that computing power seemed to double every 12 to 18 months. This prophecy is remarkably accurate. With the rise of the Internet and computing in our lives, this Law has become a basic feature of our society every much so as Newton's Law's. Key point: Every bit of key length doubles the security, making it twice as difficult to crack. However, because of Moore's Law, every year that passes makes all keys twice as easy to crack. Therefore, if it takes 1-week to break a message encrypted with a 40-bit key, it will likewise take 1-week to break a message encrypted with a 128-bit key roughly 100 years from now.

Morris Worm

Unleashed on the morning of Thursday, November 3, 1988, the Morris Worm essentially crashed the Internet. In true worm fashion, it exploited bugs in several UNIX programs (sendmail, finger) to break into machines. Once in a machine, it would then look for other machines and launch attacks against them. Due to a programming mistake, the Morris Worm would not recognize when it had already broken into a machine. As the worm multiplied, machines would get broken into over and over, eventually overloading the machine and taking it offline. The worm is named after its creator, Robert Tapam Morris.

Multitasking

The ability of an operating system to run more than one program, or task, at a time. A cooperative multitasking OS, like Windows 95/98, requires one application to voluntarily free up resources upon request so another application can use it. A preemptive multitasking OS, such as UNIX/Linux, Windows NT/2000 or OS/2, frees up resources when ordered to by the operating system, on a time-slice basis, or a priority basis, so that one application is unable to hog resources when they are needed by another program. (Also, see Multithreading and Time-sharing.) From I-gloss

Multithreading

The ability of an operating system to concurrently run programs that have been divided into subcomponents, or threads. Multithreading, when done correctly, offers better utilization of processors and other system resources. Multithreaded programming requires a multitasking/multithreading operating system, such as UNIX/Linux, Windows NT/2000 or OS/2, capable of running many programs concurrently. A word processor can make good use of multithreading, because it can spell check in the foreground while saving to disk and sending output to the system print spooler in the background.

m68k-vme-tftplilo

Linux kernel TFTP boot loader for m68k VME processor boards. Tftplilo is a highly configurable kernel and ramdisk network boot loader for BVM and Motorola m68k VME processor boards. It provides a mechanism for one or more diskless machines to interactively select a kernel boot configuration from a set of configurations defined in a single text configuration file that is transferred from the host tftp server. Each defined configuration specifies things such as Linux kernel and initial ramdisk file names which are then also transferred from the host tftp server. From Debian 3.0r0 APT

macro

/mak'roh/ n. [techspeak] A name (possibly followed by a formal arg list) that is equated to a text or symbolic expression to which it is to be expanded (possibly with the substitution of actual arguments) by a macro expander. This definition can be found in any technical dictionary; what those won't tell you is how the hackish connotations of the term have changed over time. The term `macro' originated in early assemblers, which encouraged the use of macros as a structuring and information-hiding device. During the early 1970s, macro assemblers became ubiquitous, and sometimes quite as powerful and expensive as HLLs, only to fall from favor as improving compiler technology marginalized assembler programming (see languages of choice). Nowadays the term is most often used in connection with the C preprocessor, LISP, or one of several special-purpose languages built around a macro-expansion facility (such as TeX or Unix's [nt]roff suite). Indeed, the meaning has drifted enough that the collective `macros' is now sometimes used for code in any special-purpose application control language (whether or not the language is actually translated by text expansion), and for macro-like entities such as the `keyboard macros' supported in some text editors (and PC TSR or Macintosh INIT/CDEV keyboard enhancers). From Jargon Dictionary

macro

A command that incorporates a set of other commands. You custom design a command, called a macro, from existing commands. Both the vi editor and the nroff and troff formatters use macros. The mm macro package described in this book is an example of a large collection of nroff and troff macros. From Linux Guide @FirstLinux

macro- pref.

Large. Opposite of micro-. In the mainstream and among other technical cultures (for example, medical people) this competes with the prefix mega-, but hackers tend to restrict the latter to quantification. From Jargon Dictionary

macutils

Set of tools to deal with specially encoded Macintosh files macutils is a package that contains a number of utilities that deal with Macintosh files on a Unix system. This is useful for converting BinHex-encoded files to the smaller MacBinary format before transferring them to a Mac. From Debian 3.0r0 APT

magic number

In source code, some non-obvious constant whose value is significant to the operation of a program and that is inserted inconspicuously in-line (hardcoded), rather than expanded in by a symbol set by a commented #define. Magic numbers in this sense are bad style. 2. A number that encodes critical information used in an algorithm in some opaque way. 3. pecial data located at the beginning of a binary data file to indicate its type to a utility. Under Unix, the system and various applications programs (especially the linker) distinguish between types of executable file by looking for a magic number. From Linux Guide @FirstLinux

magic number

n. [Unix/C; common] 1. In source code, some non-obvious constant whose value is significant to the operation of a program and that is inserted inconspicuously in-line (hardcoded), rather than expanded in by a symbol set by a commented #define. Magic numbers in this sense are bad style. 2. A number that encodes critical information used in an algorithm in some opaque way. The classic examples of these are the numbers used in hash or CRC functions, or the coefficients in a linear congruential generator for pseudo-random numbers. This sense actually predates and was ancestral to the more commonsense 1. 3. Special data located at the beginning of a binary data file to indicate its type to a utility. Under Unix, the system and various applications programs (especially the linker) distinguish between types of executable file by looking for a magic number. Once upon a time, these magic numbers were PDP-11 branch instructions that skipped over header data to the start of executable code; 0407, for example, was octal for `branch 16 bytes relative'. Many other kinds of files now have magic numbers somewhere; some magic numbers are, in fact, strings, like the !<arch> at the beginning of a Unix archive file or the %! leading PostScript files. Nowadays only a wizard knows the spells to create magic numbers. How do you choose a fresh magic number of your own? Simple -- you pick one at random. See? It's magic! The magic number, on the other hand, is 7+/-2. See "The magical number seven, plus or minus two: some limits on our capacity for processing information" by George Miller, in the "Psychological Review" 63:81-97 (1956). This classic paper established the number of distinct items (such as numeric digits) that humans can hold in short-term memory. Among other things, this strongly influenced the interface design of the phone system. From Jargon Dictionary

magnus

Computational group theory software with GUI The MAGNUS computational group theory package is an innovative symbolic algebra package providing facilities for doing calculations in and about infinite groups. Almost all symbolic algebra systems are oriented toward finite computations that are guaranteed to produce answers, given enough time and resources. By contrast, MAGNUS is concerned with experiments and computations on infinite groups which in some cases are known to terminate, while in others are known to be generally recursively unsolvable. MAGNUS features an intuitive graphical user interface, facilities for running different algorithms on the same problem in parallel, generation of approximations for working on otherwise infeasible problems, genetic algorithms and a plug-in package manager. From Debian 3.0r0 APT

mailagent

An automatic mail-processing tool Mailagent allows you to process your mail automatically. This has far more functionality than procmail, and is easier to configure (providing, of course, that you grok perl). As a mail processing tool, this slices, it dices, it ... Given a set of lex-like rules, you are able to file mails to specific folders (plain Unix-style folders and also MMDF and MH ones), forward messages to a third person, pipe a message to a command or even post the message to a newsgroup. It is also possible to process messages containing some commands. You may also set up a vacation program, which will automatically answer your mail while you are not there, but more flexibly than the Unix command of the same name. You only need to supply a message to be sent and the frequency at which this will occur. Some simple macro substitutions allow you to re-use some parts of the mail header into your vacation message, for a more personalized reply. You may also set up a generic mail server, without the hassle of the lower-level concerns like error recovery, logging or command parsing. The mailagent is not usually invoked manually but is rather called via the filter program, which is in turn invoked by sendmail. That means you must have sendmail/smail on your system to use this. You also must have perl to run the mailagent scripts. It is possible to extend the mailagent filtering commands by implementing them in perl and then having them automagically loaded when used. Please note that on Debian systems, mailagent can not lock /var/spool/mail directory mailboxes, and thus one must put a catch all rule saving all mail in ones home directory. This is because Debian MDA policy requires them to be setgid mail, and making anything as extensible as mailagent setgid anything negates any benefit of having group permission protection. From Debian 3.0r0 APT

mailcap

The mailcap file is used by the metamail program. Metamail reads the mailcap file to determine how it should display non-text or multimedia material. Basically, mailcap associates a particular type of file with a particular program that a mail agent or other program can call in order to handle the file. Mailcap should be installed to allow certain programs to be able to handle non-text files. From Mandrake 9.0 RPM

mailcheck

Check multiple mailboxes/maildirs for mail Mailcheck is a simple, configurable tool that allows multiple mailboxes to be checked for the existence of new mail messages. It supports both mbox and maildir-style mailboxes, for compatibility with most mail transport agents. It also supports remote POP3 and IMAP mailboxes. From Debian 3.0r0 APT

mailcrypt

An Emacs interface to the GNU Privacy Guard. Mailcrypt is an Emacs lisp package that provides a simple but powerful interface to cryptographic functions for mail and news. With Mailcrypt, encryption becomes a seamlessly integrated part of your mail and news handling environment. Mailcrypt can automatically fetch public keys to encode, decode, and verify messages, and can be configured to automate mailing through anonymous remailers. Although Mailcrypt may be used to process data in arbitrary Emacs buffers, it is most useful in conjunction with other Emacs packages for handling mail and news. Mailcrypt has specialized support for Rmail, VM, MH-E, and Gnus. Currently XEmacs ships with its own Mailcrypt, so this package should only be used with GNU/Emacs. (I.e., you don't need to install this package if your site uses only XEmacs.) From Debian 3.0r0 APT

maildir-bulletin

mail delivery agent with filtering abilities maildrop is a replacement for your local mail delivery agent. maildrop reads a mail message from standard input, then delivers the message to your mailbox. maildrop knows how to deliver mail to mbox-style mailboxes, and maildirs (a mail storing format introduced by Qmail). maildrop can optionally read instructions from a file on how to filter incoming mail, and, based upon the instructions, deliver mail to alternate mailboxes, or forward it to somewhere else, like procmail. Unlike procmail, maildrop uses a structured filtering language that's a bit easier on the eyes. From Debian 3.0r0 APT

mailfilter

A program that filters your incoming e-mail to help remove spam. Mailfilter is very flexible utility for UNIX (-like) operating systems to get rid of unwanted e-mail messages, before having to go through the trouble of downloading them to the local computer. It offers support for one or many POP3 accounts and is especially useful for dialup connections via modem, ISDN, etc. Install Mailfilter if you'd like to remove spam from your POP3 mail accounts. With Mailfilter you can define your own filters (rules) to determine which e-mails should be delivered and which are considered waste. Rules are Regular Expressions, so you can make use of familiar options from other mail delivery programs such as e.g. procmail. If you do not get your mail from a POP3-Server you don't need Mailfilter. From Debian 3.0r0 APT

man-in-the-middle attack

An attacker where the hacker interposes himself in the middle between two people. Culture: Historically, when talking about such attacks, the hacker is given male names starting with the letter M (like Mallory, Mark, Mawry, etc.). Key point: This often means that both sides of a connection really need to authenticate themselves. For example, when you log into a server, you really want to be assured it is the real server you are talking to, rather than Mark who is forwarding your requests to the real server using your identity. Key point: In the year 2000, Dug Song released a toolkit for interposing yourself in between SSL and SSH connections. It relies upon the fact that client systems do not validate the certificates on the server. Therefore, the man-in-the-middle attack can present any certificate to the client, which will not realize it is not the certificate of the server. From Hacking-Lexicon

A GTK+-based Enhanced ManPage Editor ManEdit was created due to a lack of editors for UNIX manual pages, since users expect each UNIX program/configuration/api/etc to have a manual page the lack of an editor and the high demand for what it should create eventually lead to this (long overdue) application. Although most resourced developers can create a source document using a much more advanced editor and then export to multiple file formats, the average UNIX contributor isn't up to that. Even the creators of this application were intimidated at the UNIX manual page creation process. From Debian 3.0r0 APT

From Hacking-Lexicon

meta

/me't*/ or /may't*/ or (Commonwealth) /mee't*/ adj.,pref. [from analytic philosophy] One level of description up. A metasyntactic variable is a variable in notation used to describe syntax, and meta-language is language used to describe language. This is difficult to explain briefly, but much hacker humor turns on deliberate confusion between meta-levels. See hacker humor. From Jargon Dictionary

meta bit

n. The top bit of an 8-bit character, which is on in character values 128-255. Also called high bit, alt bit, or (rarely) hobbit. Some terminals and consoles (see space-cadet keyboard) have a META shift key. Others (including, mirabile dictu, keyboards on IBM PC-class machines) have an ALT key. See also bucky bits. Historical note: although in modern usage shaped by a universe of 8-bit bytes the meta bit is invariably hex 80 (octal 0200), things were different on earlier machines with 36-bit words and 9-bit bytes. The MIT and Stanford keyboards (see space-cadet keyboard) generated hex 100 (octal 400) from their meta keys. From Jargon Dictionary

metacam

extract EXIF information from digital camera files EXIF stands for Exchangeable Image File Format, and is a standard for storing interchange information in image files, especially those using JPEG compression. Most digital cameras now use the EXIF format. The format is part of the DCF standard created by JEIDA to encourage interoperability between imaging devices. In addition to the standard EXIF fields, MetaCam also supports vendor-specific extensions from Nikon, Olympus, Canon and Casio. From Debian 3.0r0 APT

metacharacter

A character that is used to carry a special meaning, such as a caret (^, beginning of line), a dollar sign ($, end of line), or an asterisk (*, match any character). To use one of these characters without special meaning, you must either precede it with a backslash (\) or enclose it within quotation marks. Bypassing the special meaning of a metacharacter is called escaping or quoting the character. From Linux Guide @FirstLinux

metacharacter (shell metacharacters)

A metacharacter is one that represents some other concept rather than itself. For example, in entering in filenames, the metacharacter '*' doesn't represent an astrisk, but instead tells the system to match on any character. For example, looking for the filename "*.txt" will look for all files ending in the real characters ".txt". On UNIX, the most important characters are "shell" metacharacters. The reason they are important is because the shell is often used by one program to spawn another. This means that input provided to the parent program will be passed to the shell, then to the child program. If a hacker can craft special input using metacharacters, the hacker may be able to cause that shell to do something unexpected. E-mail address: A classic example is a webpage containing a FORM that asks for a user's e-mail address. The software (such as a CGI script) will often just invoke the 'mail' program using the shell. By inserting shell metacharacters into the field for the email address, a hacker may be able to execute some other program on the web server. Example: Some UNIX shell metacharacters are: [] () {} ~ # $ ^ & * \ | ; <> ? ` ' | (pipe) The pipe metacharacter links two command-line programs together, causing the output from the first program to become the input into the second program. Hackers don't care about redirecting input/output, but they will use the pipe simply as a way of confusing the shell into executing a second program. When a hacker attempts to break into a webserver, one of the first things they will do is to look for all the forms on the website and provide input containing pipe characters to see if they can force the system to execute commands. ; (semicolon) Similar to the pipe metacharacter in its ability to run multiple programs at once. However, the semicolon simply launches the programs without redirecting input/output. ` (back-quote, back-tick) The backwards quote metacharacter is similar to the pipe in that it can take the output from one command and pass it another. In this case, the output of the second program is provided as command-line input into the first. $ (dollar sign) The dollar sign prefixes a variable name. Thus, the string $FOO represents the value of the variable named "FOO" rather than the letters 'F', 'O', 'O'. In particular, you'll commonly see $IFS in attacks, where the IFS variable indicates the character used to separate lines in the shell. && and || These are logical operations used in shell programming. They look at the "result" of a program and "conditionally" execute other programs. A hacker doesn't care about this intended use, but can instead use these as yet another way to execute additional commands. See also: taint, CGI From Hacking-Lexicon

metacity

A lightweight GTK2 based Window Manager. Metacity is a small (<6K lines of code) window manager, using gtk2 to do everything. As HP says, metacity is a "Boring window manager for the adult in you.

microcode.ctl

Intel IA32 CPU Microcode Utility The microcode_ctl utility is a companion to the IA32 microcode driver written by Tigran Aivazian <tigran@veritas.com>. The utility has two uses: a) it decodes and sends new microcode to the kernel driver to be uploaded to Intel IA32 family processors. (Pentium Pro, PII, Celeron, PIII, Xeon, Pentium 4 etc.) b) it signals the kernel driver to release any buffers it may hold The microcode update is volatile and needs to be uploaded on each system boot i.e. it doesn't re-flash your CPU permanently, reboot and it reverts back to the old microcode. The ideal place to load microcode is in BIOS, but most vendors never update it! To enable microcode update, I need some kernel support, thus I need the linux kernel 2.2.18 or later, or 2.4.0 or later. From Debian 3.0r0 APT

microkernel

An approach to operating systems design which puts emphasis on small modules which implement the basic features of the system kernel and can be flexibly configured. From Linux Guide @FirstLinux

midentd

identd replacement with masquerading support. An identd replacement with masquerading support. With your average identd on a masquerading firewall, if an ident request comes in for a masqueraded connection, it will return 'ERROR : NO-USER' or something along those lines. This may be quite irritating at times, with, for example, IRC servers that won't let you in if they don't get a valid ident reply. From Debian 3.0r0 APT

mifluz

A full text inverted indexer The purpose of mifluz is to provide a C++ library to build and query a full text inverted index. It is dynamically updatable, scalable (up to 1Tb indexes), uses a controlled amount of memory, shares index files and memory cache among processes or threads and compresses index files to 50% of the raw data. The structure of the index is configurable at runtime and allows inclusion of relevance ranking information. The query functions do not require to load all the occurrences of a searched term. They consume very few resources and many searches can be run in parallel. From Debian 3.0r0 APT

mime-codecs

Fast Quoted-Printable and BASE64 MIME transport codecs At its most basic MIME is a set of transfer encodings used to ensure error free transport, and a set of content types. VM understands the two standard MIME transport encodings, Quoted-Printable and BASE64, and will decode messages that use them as necessary. VM has Emacs-Lisp based Quoted-Printable and BASE64 encoders and decoders, but you can have VM use external programs to perform these tasks and the process will almost certainly be faster. This package provides external executables for Quoted-Printable and BASE64 encoders and decoders. From Debian 3.0r0 APT

mime-construct

construct/send MIME messages from the command line mime-construct constructs and (by default) mails MIME messages. It is entirely driven from the command line, it is designed to be used by other programs, or people who act like programs. From Debian 3.0r0 APT

mime-support

MIME files 'mime.types' & 'mailcap', and support programs As these files can be used by all MIME compliant programs, they have been moved into their own package that others can depend upon. Other packages add themselves as viewers/editors/composers/etc by using the provided "update-mime" program. In addition, the commands "see", "edit", "compose", and "print" will display, alter, create, and print (respectively) any file using a program determined from the entries in the mime.types and mailcap files. From Debian 3.0r0 APT

mimedecode

Decodes transfer encoded text type mime messages. This program performs the decoding of transfer encoded text type mime messages. The message in its entirety is read from stdin. The decoded message is written to stdout; hence, this program behaves as a filter which may be placed wherever convenient. It is assumed that the message has reached its point of final delivery and at that point 8-bit text types can be handled natively. Hence, the need for transfer-encodings is not present any more. Only some cases are handled: - encoded header fields are decoded from QP or B encoding. - The charset is assumed to be iso-8859-1 - part or subparts of content-type text only are decoded - all other content-types are passed transparently. From Debian 3.0r0 APT

mimefilter

Strips some unwanted MIME parts out of a MIME message. This program may be useful as a filter on a mailing list. It strips every unwanted MIME part from a MIME compliant message, warning by email the original author about this, and outputs a MIME compliant cleaned message, to be further processed by a mailing list software. You may find it useful if you don't want certain attachments on your mailing lists, or if you want to allow just the text part from multipart/alternative messages, and so on. You can easily fine tune the list of allowed MIME types to suit your particular needs, using normal Perl regexps. From Debian 3.0r0 APT

mindi

Creates boot/root disks based on your system Mindi is a script that creates boot/root disks based on your system. It uses your kernel, modules, tools and libraries. It is use for the Mondo disaster recovery scripts and tools to create the boot CD/disks. From Debian 3.0r0 APT

mindterm

java ssh client that can be used as a web applet Mindterm is a ssh client written in java that can be used as a web applet. This package installs it so it will be available on your web site; users can then ssh into the system from most web browsers that have java support. Warning: By its very nature, installing this package and making it available on your web server constitutes exporting cryptographic software. If you're in a country that does not look kindly on this act, use caution. From Debian 3.0r0 APT
