StegFS is a steganographic file system for Linux. It offers security beyond that afforded by a regular cryptographic file system, since it not only encrypts data, but also provides a plausible deniability mechanism by securely hiding the data. It is designed to give the user a very high level of protection against being compelled to disclose its contents. StegFS extends the standard Linux file system (ext2fs), allowing normal and several levels of hidden files to coexist. This allows some data to remain hidden even if some of the keys are compromised.
shwatchr is a small Perl script that audits logins to shell accounts on Linux/*NIX machines that originate from arbitrary hosts on the Internet. When a successful login occurs and a shell is spawned, shwatchr is executed from the shell rc file and compares the host from which the login originates against a list of known/allowed hosts. If a match is not found then shwatchr can be configured to either send an email to a separate alert email address that contains the time and host from which the login took place or issue a warning and proceed to kill all user shells. shwatchr does not require root to execute and hence users can have some measure of knowledge and security over who is logging into their accounts even if they can't modify firewall or tcpwrapper rulesets, or look at system logs.
bpowerd is a daemon and makes proper use of the system log for error checking. It uses init's powerstatus calls to do it's dirty work, instead of calling shutdown itself. bpowerd is easy to compile and configure, using GNU's autoconf and providing explicit instructions for testing and installation. bpowerd was created using specs provided from the manufacturer, as opposed to reverse-engineering.
The console-tools package allows you to set-up and manipulate the Linux console (ie. text screen and keyboard), and manipulate console-font files. It was developed from version 0.94 of the standard `kbd' package, and integrates many fixes and enhancements, including new kbd features up to 0.99.
SAGU, which is a portuguese acronym for "Sistema Aberto de Gestão Unificada", was originaly designed to automate all of what that happens between a student and their Educational Institution. This relationship happens at the academic, financial and administrative levels, and SAGU has subsystems dedicated to these levels. SAGU can be tailored to fit the needs of any Educational Institution.
