XMakemol is a program written for UN*X operating systems in ANSI C using the X, Xt and Motif libraries. It can be used to view and manipulate atomic and molecular data given in xyz format. XMakemol is a mouse-based application and many features can be accessed by clicking or dragging the mouse on the main window. Additional popup dialogs offer a number of additional features. Here is what an XMakemol session might look like. The system is a bucky ball and the Measure dialog is showing the measurement of bond-lengths, angles and a torsion angle. XMakemol can produce output in PostScript (black and white or colour)and in xpm format (which can be translated to gif format using xpmtoppm and ppmtogif). XMakemol can also produce a series of xpm files which can be translated into an animated gif file using the bundled utility xmake_anim.pl (formerly gmake_anim.pl). The one above is an animation of the "viagra" molecule (sidenafil).

courierpassd is a password changing utility that uses the courier-authlib authentication library to change user credentials. Its interface follows that of poppassd.

courierpasswd is an authentication and password changing utility that uses the courier-authlib authentication library to find user credentials. Its interface follows that of Daniel J. Bernstein's checkpassword program.

courieruserinfo is a utility for retrieving user account information. Account information is accessed through the courier-authlib authentication library.

Crank is short for "CRyptANalysis toolKit", and its overall purpose is to provide a powerful and extensible environment for solving classical (pen-and-paper) ciphers, providing as much automation as possible. Classical ciphers include common schemes like monoalphabetic substitutions, where each letter of the alphabet is mapped to another (usually different) letter consistently through the text. The first version of Crank is restricting itself to these special ciphers. Other algorithms forever devoid of Crank's attentions include Enigma, RSA, DES, MurkelFish, or anything else invented after 1900. They're hard(er).

"dds" is a program to scan for a limited set of distributed denial of service (ddos) agents. At present, it scans for active instances of "trinoo", "Tribe Flood Network" ("TFN") and "stacheldraht" agents, which were compiled using the default values in known source distributions, such as those found at: http://packetstorm.securify.com/distributed/ It will *not* detect TFN2K agents. For analyses of the three distributed denial of service attack tools it scans for, and the methods being used by dds to identify them, see: http://staff.washington.edu/dittrich/misc/trinoo.analysis http://staff.washington.edu/dittrich/misc/tfn.analysis http://staff.washington.edu/dittrich/misc/stacheldraht.analysis

The digest utility is a wrapper for the md5, sha1, sha256, sha384, sha512, rmd160, tiger and whirlpool message digest algorithms (also known as hashes, checksums or "fingerprints").

Doscan is a tool to quickly scan your network for machines listening on a TCP port, opening thousands of TCP connections in parallel. Features High scanning rate: five to ten minutes per 100,000 addresses (which are sparsely populated with hosts), with rather conservative timeouts. Load distribution: doscan scans the addresses in a seemingly random order. If your scan host is connected to a central router, this ensures that the load is distributed across your network, and you are stress-testing just a single router, and not your edge devices. Low memory consumption: memory usage is proportional to the number of hosts which have responded so far, and to the number of parallel connections. The total number of addresses does not influence memory usage in any way. Can collect responses: doscan optionally records data which is sent by the hosts which are being scanned. You can even specify a regular expression to extract part of a server banner, and a message to send to trigger a response (great for determining HTTP server versions). Extensibility: It is possible to add special handlers for TCP-based protocols, using a straightforward interface. It supports scanning the vulnerable Microsoft DCOM implementation.

BFBTester will perform checks of single and multiple argument command line overflows and environment variable overflows. BFBTester will also watch for tempfile creation activity to alert the user of any programs using unsafe tempfile names.

This tcpwrap extension for PHP handles /etc/hosts.allow and /etc/hosts.deny files.
