John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
The Enhanced TightVNC Viewer, SSVNC, adds encryption security to VNC connections. The package provides a GUI for Windows, MacOS X, and Unix that automatically starts up an STUNNEL SSL tunnel for SSL or ssh/plink for SSH connections to any VNC server and then launches the VNC Viewer to use the encrypted tunnel. On Unix and MacOS X, a VNC viewer with many new features is provided. The short name for this project is "ssvnc", for SSL/SSH VNC viewer.
Zsh is a UNIX command interpreter (shell) which of the standard shells most resembles the Korn shell (ksh). It includes enhancements of many types, notably in the command-line editor, options for customising its behaviour, filename globbing, features to make C-shell (csh) users feel more at home and extra features drawn from tcsh.
Podget is a simple podcast aggregator optimized for running as a scheduled background job (i.e. cron). It features support for downloading podcasts from RSS and XML feeds, for sorting the podcasts into folders and categories, for importing podcast URLs from iTunes PCAST files and OPML lists, automatic M3U and ASX playlist creation, and automatic cleanup of old podcasts. It also features automatic UTF-16 conversion for podcasts hosted on Windows servers.
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
Logrep is a secure multi-platform tool for the collection, extraction, and presentation of information from various log files. It features HTML reports, multi-dimensional analysis, overview pages, SSH communication, and graphs, and supports 25 popular systems including Snort, Squid, Postfix, Apache, Sendmail, syslog, iptables/ipchains, xferlog, NT event logs, Firewall-1, wtmp, Oracle listener, and Pix.
smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.
