[rancid] Show tech on latest Procurve software

[Aleksander Vines]

Hi all,


Is there a way of altering the output of rancid, or which commands it runs, or how the 'diff'ing' works?


We seem to have a problem with the latest hp software, where 'show tech transceivers' seems to include a call to 'show time'. Hence it notices a diff in the output timestamp and and it's fairly annoying if you actually want to keep track of changes. 


Ref. https://community.hpe.com/t5/ProCurve-ProVision-Based/Command-behavior-change-in-KB-16-05-0003-5406R-firmware/td-p/6992013

Yes, it's fairly easy to filter out individual lines by editing the
filter inside the perl scripts to make them go away. I have done this
many, many times. The only trick is that when you upgrade you might lose
your change, so save a copy or diff that you can re-apply later.

In this case, the place where you'd put the filter is in
~rancid/bin/hrancid in the routine "ShowTechTransceivers"

Right at the top where it has 'next if (...)'

either above or below that you can add a line that says something like
next if (/thing I want to match here/) which will skip that line.

That worked perfectly. Thanks for the fast reply.


For reference, if anyone else have issues with new procurve software, this is what I added:



# This routine parses "show tech transceivers"
sub ShowTechTransceivers {
    ...
    while (<INPUT>) {
        ...
        # These next two lines are new
        next if (/[A-Z][a-z][a-z] [A-Z][a-z][a-z] [0-9]+ [0-2][0-9]:[0-5][0-9]:[0-5][0-9] 20[0-9][0-9]/);
        next if (/show time/);
        next if (/^(\s*|\s*$cmd\s*)$/);
        ...
}


Thanks,
Aleksander Vines

Would someone confirm that these filters work:

My HPs aren't new enough to show the time field.
But it looks innocuous enough.
