[rancid] Re: Using RANCID with an SSH tunnel

[Chris Gauthier]

I'm not sure how well using Perl to set up your ssh tunnel then execute 
rancid would work.  I think you might do better if you wrote an expect 
script or some form of a shell script that then called rancid.  I am not 
a programmer by trade, so I m certainly not the most expert person here, 
but those are my opinion of how you might be more efficient.  Btw, 
rancid is written using the Perl and Expect languages.

Unfortunately, in this situation, I can't add a route to allow the networks to talk to each other.  The only way that the 2 networks have access to each other is through a dual-homed server that has a NIC on each network.  Below is a simple diagram of the network:

Now I am no Linux expert, but I have been playing around with SSH port forwarding and I am thinking the best way to accomplish this is to create a shell script to open a tunnel to the 192.168.0.0 network before the RANCID job executes.  A coworker suggested creating a perl script that RANCID would call to open the tunnel then grab the config, but I am not familiar with perl and having trouble finding examples of how to integrate a perl script into RANCID.
