Dont you guys think it is a very tedious process to keep track of your networking devices configuration. Yah you know.. > copy run-config/start-config tftp ip.address .
So, instead of wasting my time doing that manually, i use Rancid + CVSWeb to monitor and keep track of my cisco devices configuration changes. As usual, my favorite platform is FreeBSD. The installation process can be referred to this tutorial.
After installation, several configurations need to be made especially, ~/.cloginrc which stored all your authentication method and password and also router.db that stored information about the router. In .cloginrc you can define what type of login method that you want to use, either telnet or SSH. For example:
add type ssh ip.of.the.router
add password ip.of.the.router passwordbongok passwordbongek
To test wether it's working or not, you can use a tool which is part of rancid, clogin.
$ clogin ip.of.the.router
if you can login and manage to get into global and configuration mode. Then you're good. After that all you need to start your rancid by typing rancid-run. Here is the screenshot of my cvsweb.
So the last step is to make sure every hour rancid will check for configuration changes on the routers. So all you need is crontab.
@hourly /usr/local/bin/rancid/rancid-run . Thats it.
