Rancid compat script for pfSense

Friday, August 31st, 2012

RANCID stores the configuration of network devices http://www.shrubbery.net/rancid/ and is useful to track any changes and replace a dead device. I have written a simple compat script for pfSense that works well enough to get RANCID to parse and store it. It just emulates a Cisco device, rather than adding a new parser.

 

To use it you need to create a user in pfSense which then has a public key assigned, I have named mine `rancid`. Follow these steps to set it up

      • Create a SSH public key on the RANCID server under the user’s account who performs the scheduled run
      • Under the pfSense user admin page add the public key to the rancid account but prefix it with
        command="/home/rancid/bin/rancid-compat"
      • On the pfSense box make the directory /home/rancid/bin and place the rancid-compat script in there, ensure it has execute permissions (750)
      • Add the pfSense hostname to your routers.db as a cisco device
      • Set up the RANCID cloginrc connection options in .cloginrc
        add user pfsense.example.com       rancid
        add cyphertype pfsense.example.com aes256-ctr
        add autoenable pfsense.example.com 1
        add method pfsense.example.com {ssh}
      • Now execute rancid-run and hope for the best!
