[rancid] ASA Config for Rancid

Thu Sep 14 15:41:12 UTC 2017

I just read the info page and am actually not impressed.  It’s not upgradable.  It does not run a “standard” installation of RANCiD—it compiles its own binaries and installs itself customized for Zenoss.  It only works with SVN, so no CVS or GitHub support.  Since the version is from 2015, I expect it’s probably on RANCiD 2.3.2 or some old version like that.

Hmm...
https://www.zenoss.com/product/zenpacks/rancid-integration-community

We are in fact using ZenOSS for monitoring/alerting (free version, we can’t afford the licensed version).  Now THAT is something interesting to evaluate.  I’ll ask someone on my team to evaluate that.  Allowing telnet <shudder> is another possibility.  We had also considered shifting everything into PRIME Insfrastructure (which we will anyway for other reasons than config backups - we did get enough licensing for that at least), but RANCiD has some capabilities that I like that PRIME doesn’t do so well - consider all the hijinks you can do in Linux, like aggregating certain parameters occurs across a subset of devices by doing something like... I don’t know if I have the syntax right, this is just quickly off the top of my head “echo $[`for $(find –name <pattern> –exec egrep –L <chassis_model> \{} \; ) do  grep <another_regex>   |   awk ‘{print $3}’   ;   done  |   tr ‘\n’ ‘+’ | sed ‘s/+$//’`]” . We haven’t yet found a good way to do that in PRIME.

Thanks everyone for the help!

Zenoss is a tool that has RANCiD integration/pluin connectivity.

Sounds like a fun problem to have. There are some open source NMS products out there that integrate with RANCID and can probably write out the file for you, otherwise you would need to modify how RANCID works and have it switch to the type of device after login with a show ver command or something similar. Let us know if you come up with anything though, I like the idea of having the device login decide the type, or at least a discovery mechanism for RANCID that would write out the proper lines to .cloginrc.
