FreeBST ports monitoring is a simple solution for monitoring what has changed in installed ports on a given FreeBSD machine, i.e. what ports were upgraded, installed, or removed. No fancy dependencies: just plain Ruby and shell commands. Results in plain English text are emailed to a given address.
MAC vendor check is a script that gathers MAC addresses in a network and creates a list of the vendor of each device. It can be use to quickly check whether strange devices are present on the network, especially if there is no dedicated management software (like Cisco Works) in use on the network.
SSVN is a wrapper script for svn to store file permissions in a Subversion repository (along with the versioned file). Permissions and ownership can be restored later. A Unix-like file permissions schema is stored, and GID and UID are stored numerically. This means that this script is not portable to non-Unix systems.
