[rancid] HP switch garbled output results in Expect timeout

[Gordon Stratton]

Running stock RANCID version 2.3.3 on Debian Squeeze (not the Debian
package, this is installed from source):

expect                              5.44.1.15-1
tcl8.5                              8.5.8-2

It seems that some component is garbling output and causing Expect to
time out on all of my HP switches. Here is some sample output:

--- 8< ---

# HOME=/root ./hlogin -c 'show version' <MYSWITCH>
spawn hpuifilter -- telnet <MYSWITCH>
Trying 10.194.182.114...
Connected to <MYSWITCH>.
Escape character is '^]'.

Pr key to key to ctntieue

--- >8 ---

I noticed that the line:

ProC1HProCurve J4899B Switch 2650

has Pro repeated with an extraneous "C1H", and the last line (which is
the culprit, I think):

Pr key to key to ctntieue

should obviously be "Press any key to continue", which causes Expect to
hang.

Does anyone have any ideas about what could be causing this? I run
RANCID on a daily basis, and the next run after I upgraded some
packages, I noticed RANCID runs started timing out:

2010-06-14 08:24:44 upgrade libc6-dev 2.10.2-9 2.11.1-3
2010-06-14 08:24:45 upgrade libc-dev-bin 2.10.2-9 2.11.1-3
2010-06-14 08:24:45 upgrade locales 2.10.2-9 2.11.1-3
2010-06-14 08:24:46 upgrade libc-bin 2.10.2-9 2.11.1-3
2010-06-14 08:24:49 upgrade libc6 2.10.2-9 2.11.1-3
2010-06-14 08:25:30 upgrade udev 154-1 157-1
2010-06-14 08:25:31 upgrade binutils 2.20.1-9 2.20.1-10
2010-06-14 08:25:32 upgrade libgeoip1 1.4.7~beta3+dfsg-2 1.4.7~beta5+dfsg-1

I don't know if any of these could have caused the problems, but the
coincidence is enough to make me think there might be something to it.

Thanks for any ideas,

Gordon
