[rancid] Re: Cisco IPS V5.X & Rancid

The terminal type was what 'made it angry'.
However, I did fix that and here is the diff for rancid-fe:
diff --recursive new/ old/
diff --recursive new/rancid-fe old/rancid-fe
35d34
< elsif ($vendor =~ /^ciscoips$/i) { exec('ciscoips', $router); }
The attached are my scripts for the IPS: ipslogin and ciscoips.
The AGM setup did not work for me. I'll dig into that in a bit.
