Fush is a Unix shell replacement. It provides improved support for logging the user's commands. Fush allows you to restrict and log everything that a user does. You can restrict shell operators, maximum command length, background tasks, or limit which commands can be executed from the command line. A list of MD5 sums is kept on all system binaries. When a user tries to execute a command, an MD5 hash is generated and is compared against the user's ACL. If the MD5 sum and full path match an approved command in the ACL, the command is executed.
Shuriken is an XML-based tool for Linux system administrators to set up spans of time when the system should be up. Using the RTC daily alarm (requires BIOS, hardware, Linux support), the system will automatically power-on (if it is off) for these intervals. Automatic power-off is supported, but this feature is not recommended if users intend to log in to the system and not have it shut down on them.
xSH-Paranoia Patch is an project started for admins who work in large system environments. It allows you to see which user executes which command, when, where, and from what IP address. It logs everything to syslog, and with syslog-ng, you can log it to another machine where no user should/would have access. Currently supported shells are bash and tcsh.
