It's much cleaner with this version, but it's still failing on the pager or an expect loop.  I would move over to version 6 assurewave but I think I would hit some of the bugs, so I'm holding on to 4.2.207 for a bit longer.

Here is what's happening:

rancid at netman:~/bin$ rancid-run -V
rancid 2.3.3
rancid at netman:~/bin$ expect -v
expect version 5.43.0  - debian Lenny 5.43.0-17 build

rancid at netman:~/bin$ wlclogin -c 'show run-config commands' cisco-wlc4
cisco-wlc4
spawn ssh -c 3des -x -l adminuser1234 cisco-wlc4

When the 'show run-config commands' is run from CLI, I am able to page properly through the file.  Can anyone shed any light on what might be causing what appears to be an expect loop?

Thanks,
