- RANCID monitors a router's (or more generally a device's)
- configuration, including software and hardware (cards, serial numbers,
- etc) and uses CVS (Concurrent Version System) 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)
- * run various commands to get the information that will be saved
- * cook the output; re-format, remove oscillating or incrementing data
- * email any differences (sample) from the previous collection to a
- mail list
- * and finally commit those changes to the revision control system
