RANCID is a software package that allows for versionning of Cisco (and other devices) configurations. It would be useful for us to monitor the configuration of existing switches.
See also ConfigurationManagementService.

A basic installation was performed on rtr1-canix2.koumbit.net but will be rolled back because it's not necessarily the right place for it (maybe log.koumbit.net would be better?). The installation was performed and controlled by Puppet.
