problem with Cat6000's

Hi.
I'm using rancid-2.2 on an OpenBSD 3.0 box, tcl/tk 8.3.3, expect 5.24.
Works fine for my various Foundry's and IOS devices (2500s, 4000's,
7200's, etc.)
However, on the switch side of the 6500's (a 6506 and 6509), and also
on a 2980
I get the following in my log files:

starting: Thu Jan 24 14:16:24 EST 2002
Trying to get all of the configs.
cat6506: End of run not found
end
cat6509: End of run not found
end
cat2980 End of run not found
end
=====================================
etc.

a cloginc -c "cmd1;cmd2" switch-name
works fine, no errors.

I saw the same thing when I was running rancid-2.1 on Solaris 2.6,
figured upgrading to OpenBSD, newer versions of rancid and expect
would solve the problem, but it remains.
The prompt on the switches is:
switchname>
and
switchname> (enable)
when in enabled mode.

All the switches are running IOS which uses SSH, I am running OpenSSH 3.0.2

The only relevant lines in the .cloginrc is:

add method cat650* ssh
add method cat2980* ssh

and

add cyphertype * {3des}

Thanks.

Here's the output of clogin -s "show version" to one of the switches:

$ clogin -c "show ver" cat6509
cat6509
spawn ssh -c 3des -x -l rancid cat6509
rancid at cat6509's password:

This is apparently a problem with the SSH implementation in CatOS - when
RANCID says "exit", the switch closes the connection before echoing the
exit command, which causes the script to not see that things completed
properly. The following diff shows a fix to cat5rancid to deal with this.
Note that your line numbers will be different - I have other unrelated
changes.

***************
*** 1051,1056 ****
--- 1050,1060 ----
TOP: while(<INPUT>) {
tr/\015//d;
if (/> $enable$ ?exit$/) {
+ $clean_run=1;
+ last;
+ }
+ # CatOS SSH client stomps on the "exit" command echo...
+ if (/> $enable$*Connection*/) {
$clean_run=1;
last;
}
