[rancid] Printed artifact when rancid logs into a switch (^[[53; 211R)

[Remsik,Robert]

Hello!


I'm trying to troubleshoot a case where rancid's not backing up a device properly because it can't login.


... In the test.log file: ...

starting: Tue May 16 15:37:25 MDT 2017



Trying to get all of the configs.
couldn't compile regular expression pattern: parentheses () not balanced
    while executing
"expect {
        -re "\[\n\r]+"  { exp_continue }
        -re $reprompt   {}
    }"
    (procedure "run_commands" line 12)
    invoked from within
"run_commands $prompt $command"
    ("foreach" body line 159)
    invoked from within
"foreach router [lrange $argv $i end] {
    set router [string tolower $router]
    send_user "$router\n"

    # device timeout
    set timeout [find t..."
    (file "/path-to-rancid/rancid-3.5.1/bin/hlogin" line 657)^M
10.100.116.17: missed cmd(s): all commands
10.100.116.17: End of run not found

... which after trying to run hrancid I get the same error and it doesn't write the correct debug file 'z'.  Looking at the .new file I see it didn't process any of the commands. ...

rancid at truck:~/bin$ hrancid -t z -d 10.100.116.17
executing hlogin -t 90 -c"show version;show flash;show system-information;show system information;show module;show stack;show tech transceivers;show config files;show config status;write term" 10.100.116.17

rancid at truck:~/bin$ ls z
ls: cannot access 'z': No such file or directory


rancid at truck:~/bin$ ls *.new
10.100.116.17.new




rancid at truck:~/bin$ cat 10.100.116.17.new
;RANCID-CONTENT-TYPE: hp
;

... When I run hlogin with the -c option I get the same error.  However when I remove the -c option to confirm if I can login at all, I can, with an artifact of (^[[53;211R) at the prompt.  Logging in via SSH doesn't provide this artifact. ...

... Curiously the problem is not widespread.  ~1% of my environment and after talking with a college (who's running the latest version of rancid - he reported the problem to me) it appears to be switch version dependant as only some specific versions of code.  He confirmed by upgrading and downgrading code on an HP5412Rzl2 in his environment.  I was able to locate 2 more versions of code that had the same error.

Has anyone encountered this before or know how to remove the artifact?  Thank you in advance,
