I used to post in Blogsome couple of years ago before until the site closed down. In here, I have posted blogs about RANCID which is a set of scripts (PERL) used to monitor network devices configurations and maintain history of changes via CVS (Concurrent Version System). Here are some of my post about RANCID (version 2.3.2) which are now archived in the Internet which might be of used to someone interested in RANCID and customizing it.
RANCID under the hood (posted October 23, 2011)
This post show the internal working of RANCID and understand how it works and which scripts are executed and dependent on each other
RANCID additional commands (posted November 2, 2011)
Normally, RANCID executes some commands when connecting to network devices, this post discusses how to include additional commands.
RANCID Customization (posted November 9, 2011)
This post is discusses how to poll different groups of network devices with different sets of commands
I hope in the future I can update my knowledge with the current release of RANCID.
