[rancid] Erratic "e" and "x" characters with clogin and hlogin

[Ryan Shea]

We run rancid against two different kinds of devices, one using clogin and
one using hlogin, but we often see erratic config differences. It seems
that almost randomly "e" or "x" characters will show up toward the beginning
of certain lines. Here are a few examples:

- !xiBGP table version is 0, local router ID is 10.10.10.10
+ !BGP table version is 0, local router ID is 10.10.10.10

This is troubling because with the number of devices we check there is
almost always a flake-out on a few of them, making config change
notifications very spammy.

I am running this system on on an Ubuntu Hardy server with expect version
5.43.0. It did not look like the expect patch had anything to do with these
random characters, so I have not patched/hacked my expect. In the past I
have seen this - as well as seemingly random spaces at the beginning of
lines with Cisco ASAs - on RHEL 5 machines as well. Any pointers in the
right direction would be appreciated.

Thanks,
Ryan

You're not alone. This seems to be an undocumented feature of the ASA series,
although it only happens when there's been a config change, not spontaneously
on it's own.

That is really too bad. At least I have a platform where it flakes out
reliably enough that debugging would probably be worthwhile. I can try
pulling the clogin and hlogin from the bleeding edge version of Rancid to
see if that helps.

This is caused by the pager on the PIX/ASA. I've not been able to
come-up with a fix for this.
