Sshguard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. Sshguard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng, metalog, multilog, raw messages), and detects attacks for many services out of the box, including SSH, several ftpds, and dovecot. It can operate all the major firewalling systems, and features support for IPv6, whitelisting, suspension, and log message authentication.
Stash is a package manager for non-root users. It makes it easier for you to install, track, and maintain packages and modules in your home directory. It does this by detecting the type of package or module you are installing and passing all the correct command line arguments to the relevant configure scripts and/or makefiles. It is extensible via custom packages, and tracks both architecture dependent and independent packages in separate directories so that they can be shared across systems. Package tracking uses symlinks in a manner similar to GNU stow. It supports autoconf, Perl and Python modules, imake (xmkmf), PMK, and many custom packages.
The stmpclean utility removes old files (and old empty directories) from the specified directory. It is meant to be used to clean directories such as "/tmp" where old files tend to accumulate. stmpclean never removes files or directories owned by root, which is a feature, not a bug. Great care is taken while descending into the directory, and the operation is secure. Anything that's not a directory, regular file, or symbolic link is also left alone (because programs like screen(1) create sockets and FIFOs under /tmp and expect them to be long-lived). Unlike other programs that do the same task, stmpclean never forks and consumes limited amount of memory. If stmpclean determines a race condition it will log the situation and exit with a failure.
stowES (stow Enhancement Script) is a Perl script which tries to ease the use of the "stow" packaging program and software which can be compiled and installed with autoconf. It automates the compilation and installation of software packages and provides some useful functions to maintain your stow packages (e.g., list packages, check packages for integrity, etc.).
