RANCID

RANCID

RANCID ("Really Awesome New Cisco confIg Differ") is a network management application. RANCID monitors a router's (or more generally a device's) configuration, including software and hardware (cards, serial numbers, etc) and uses Concurrent Version System (CVS) or Subversion (SVN) to maintain history of changes.

RANCID does this by the very simple process summarized here:

* login to each device in the router table (router.db) using Expect for automation,
* run various commands to get the information that will be saved,
* cook the output; re-format, remove oscillating or incrementing data,
* commit those changes to the revision control system,
* and finally email any differences from the previous collection to a mailing list.
