[rancid] Extreme Switches with Unsaved Configs

Hi everyone,

I'm running rancid-2.3.2a9 and I'm having a problem with our Extreme switches. Whenever the config is not saved on an Extreme switch and I run rancid-run I only get a bunch of errors in the log and no config is retrieved and diffed. (It appears as if the * that gets put in front of the cli prompt causes this, since that seems to be the only difference between a saved and an unsaved config.)

I searched through this archive and found a patch for 2.3.2a6 by Tore Anderson (thank you for this) (link: http://www.shrubbery.net/pipermail/rancid-discuss/2007-May/002218.html) but even reverting back to the older version and patching it, I still encountered the same problem.

I am just wondering if anyone has a solution for this, for either 2a9 or 2a6. Any help would be greatly appreciated.

The output is as follows:
-------------------------------------------------------------------------------------
Trying to get all of the configs.
couldn't compile regular expression pattern: quantifier operand invalid
while executing
"expect -nobrace -re {* 300e48-x.([^#>\r\n]+)?[#>]($[^)\r\n]+$)?} {} -re {[

"expect {
-re $reprompt {}
-re "\[\n\r]+" { exp_continue }
}"
(procedure "run_commands" line 23)
invoked from within
"run_commands $prompt $command"
("foreach" body line 152)
invoked from within
"foreach router [lrange $argv $i end] {
set router [string tolower $router]
# attempt at platform switching.
set platform ""

(file "/home/rancid/bin/clogin" line 715)^M
172.x.x.x: missed cmd(s): show configuration detail,show slot,show configuration,show version,show diag,show memory,show switch
172.x.x.x: End of run not found

-----------------------------------------------------------------------------------------

This repeats a few times.

Thanks in advance, I really appreciate your assistance.

Mr. Heasley,

Attached, please find the output of clogin -d

I noticed that the script seems to stall out on the last line and never times our or finishes. If I hit enter a few times I see these lines scroll by afterwards:

spawn id exp0 sent <\r>
spawn id exp4 sent <\r\n* 300e48-0.45-HH-IDF:2 # >

* 300e48-0.45-HH-IDF:2 # spawn id exp0 sent <\r>
spawn id exp4 sent <\r\n* 300e48-0.45-HH-IDF:2 # >

Thanks for your help, I really appreciate it.

Sven

grumble. I think this hack will fix it.
