It features service-oriented configuration, support for network profiles, which is useful for notebooks, support for macros, easy migration to another network environment by redefining macros, easy distribution to many hosts, syslog logging support for iptables errors and dropped packets, an interactive mode for manually configuring "on the fly", a batch mode for execution from shell scripts, and a library mode for using the flex-fw functions in your shell scripts.
BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.
