Integrating rancid with OpenNMS...

Post #1 of 3 (503 views)

I am about to (today) integrate Rancid with an OpenNMS installation that
I have. The idea is that if new routers are discovered in OpenNMS I
will add them to /etc/hosts, cloginrc and router.db. Has anyone done
this? I am planning on writing this in perl; and I have already written
a password basher that produces the proper output for cloginrc and
router.db. Here are the scripts that I plan to write today (unless
someone can point me to something similar)

rancid_mv <oldname> <newname>
dangerous cvs hack + change in /etc/hosts, router.db and cloginrc
rancid_reip <oldip> <newip>
simple change in /etc/hosts
rancid_new <name> <ip> [<description>]
detect password and os, make entries in /etc/hosts, router.db and cloginrc
rancid_delete <name>
delete entries in /etc/hosts, router.db and cloginrc

Thanks for your time.

I am not familiar with opennms, but you might consider entirely re-creating
the files on some regular basis than bother with intricacies of editing. That
is what I do, but the source is a database.

If your source keeps track of whether the device is 'up' or 'down' or in
'testing' (unmanaged) state, this will work nicely. Putting anything in
that third column in the router.db other than 'up' will suspend collection.

When you don't have any concept of whether a device should be managable
now (c.f., a 'collect config' flag on the device), you have to treat the
devices as up, and you will thus have to expect to more carefully read
the 'device down' emails the admin aliases get from RANCID (or ignore them).

Since the number of absolute records, even for a large network, is
relatively small, your build scripts could quite reasonably run every hour..
