[rancid] anyone have rancid working for a nexus 5000?

[Nick Buraglio]

I had some issues with the nexus as well and had to make some small
changes.  I also cleaned out some of the stuff that was causing it to
diff every time (mostly flash related stuff).  I had to do some
similar stuff to the xrrancid script for use with the CRS we had at
SuperComputing 2010.  Diffs and stuff can be found at
http://buraglio.com/dev/viewvc.cgi/ if anyone wants them.

when trying to get the config from a nexus 5000.

The problem turned out to be "show version build-info all" - ie:

nexus5000-1# show version build-info all
                         ^
% Invalid command at '^' marker.
nexus5000-1#

plz report that to cisco.  running a command that isnt supported on the
platform should not cause it to disconnect the client.

I don't think it's a cisco problem.  In the above example I did a
"clogin nexus5000-1" and then typed in "show version build-info all"
at the prompt.  Got the error msg & new prompt - no disconnect.

you will have to try it with all of the preceeding commands too.

did - no problems.  Then I remembered that clogin adds a "term len 0"
when you give it a list of commands, so did that, repeated the
commands again & got the missing newline at the end out the 'show
version' output.   But no disconnect.

  ... snip ...
I must be especially slow today - what am I looking for?  Looking in
nexus5000-2.raw shows some extra "^M"s, but it's still the same as my
earlier example - no output:

plugin^M
 Core Plugin, Ethernet Plugin^Mnexus5000-2# show license^M^M
                                 ^ where the newline?
so, show version is missing a newline at the end of it's output.

Yes & that's the problem - thanks!!  Adding a "term len 60" before the
"show version" and a "term len 0" after fixes it.  So my commandtable
now looks like this:
@commandtable = (
       {'term no monitor-force'        => 'RunCommand'},
       {'term len 60'                  => 'RunCommand'},       # -LR-
       {'show version'                 => 'ShowVersion'},
       {'term len 0'                   => 'RunCommand'},       # -LR-
       {'show version build-info all'  => 'ShowVersionBuild'},


Thank you!
