[rancid] Nexus 7000 series backup issues.

Quick clarification, I did not need to load the linux expect hack on our
Redhat Enterprise 64 Bit 5.8 server, however we were not able to determine if
Redhat had actually included it or not already in their implementation of
expect 5.43.


Okay I figured it out. On my Nexus 7000 version of NXOS 5.1(3) if you remove
the banner motd completely the system defaults to the following " #User
Access Verification#Using keyboard-interactive authentication." Which of
course includes the "#" symbol preventing the rancid from logging in
properly. As soon as I set a new banner motd then the problem goes away. 


So this all worked and the linux expect hack did not have to be used.

Does it go away if you remove all your banner/motd?

I know this has been discussed before, but I still do not seem to be able to
find the solution to backing up the Nexus 7000 that I have.


nexus_1 clogin error: Error: TIMEOUT reached

nexus_1: End of run not found



If I use clogin I notice that it is getting hung up at the password prompt.
The prompt has not been changed from the standard Cisco uses. If I enter the
password in .cloginrc, everything is fine. I haven't been able to figure out
why it stops at this point, it is using the same login paramters as my other
devices and they are all working fine.


Not sure where to go next.
