columbus -- Columbus - automatically detect and set network configuration
http://columbus.sourceforge.net/
Columbus automatically detects your location from a set of pre-defined
locations (identified by a known host, it's IP address and it's MAC
address) and symlinks specific system files accordingly. It also
hooks this up to apmd and together with viking, a link monitor, it can
automatically re-sync your network each time your network cable has
been unplugged.
