The RANCID FAQ ( http://www.shrubbery.net/rancid/FAQ ) says:
Q. Are there any characters in the banner that rancid has problems with OR
I changed the device's command prompt and now collection is failing?
A. The trickiest part about clogin (et al) is recognizing the prompt
correctly. clogin looks for '>' and '#' to figure out if it is logged
in or in enable mode. So if you have a '>' or '#' in your login banner
(or other motd), then clogin gets all confused and will not be able to log
in correctly, and thus rancid will fail.
Don't use '>' or '#' in your prompt or in your banner or other motd.
Suggest you go through the FAQ and see if that warning or any
other section in there applies to you. If you can't fix it, come back
here and post the exact text of the "odd errors" that you're getting.
