ssh-forcecommand is a script to safely execute remote commands via ssh. It is especially aimed at automated remote commands (in which ssh keys are not secured via password), where a compromise of the remote system could also compromise the local system. To prevent this, ssh-forcecommand can be invoked through the ssh configuration, which will limit the remote system so that it can only execute a set of statically defined commands. This way, compromising the local system is made much more difficult.
ColorLogs is an output-colorizing Perl script intended to have command output piped through it to a terminal. It allows easy creation of new highlighting configurations using simple text matches, globs, or regular expressions. It works transparently even in interactive contexts with scripts that produce prompt lines and wait for user input. Patterns are provided for Ant and Maven output. This version started as a fork of v1.1 from resentment.org, but numerous improvements have been made since then.
L++ is a multiplayer Lemmings remake which lets you play Lemmings against (or in a team against) others (up to eight players over a network). It has a built-in level editor. Lemmings is a game in which you guide one to ninety-nine lemmings from an entry door to an exit. There are commands for stopper, exploder, digger, builder, parachuter, and much more.
zzuf is a transparent application input fuzzer. Its purpose is to find bugs in applications by corrupting their user-contributed data, which frequently comes from untrusted sources on the Internet. It works by intercepting file and network operations and changing random bits in the program's input. zzuf's behavior is deterministic, making it easier to reproduce bugs.
