[rancid] stopping command from being run

[Vacheslav]

Thank you very much for your insight. The 9ks have been bugging me for a
long time with the little of use flash log and now it's gone thanks to you.
But I added the cisco-nx9k to rancid.types.base and did not modify
rancid.types.conf and just changed the type in the db file and the miracle
happened!

Hi Mike.  I am running 3.7 also, in my case on RHEL7 with git.  I am very
happy with it.

As I understand it, editing the perl modules to try to change commands
issued to devices is a very wrong approach; it means you can't easily
upgrade and your installation will be weird and difficult to get advice for
online.  so I strongly recommend you carefully revert any such changes you
made.

The files rancid.types.base (base types, do not edit) and rancid.types.conf
(site custom device types) determine what commands are run for specific
devices.

So for example: on my Cisco Nexus 9Ks, I did not want to run the "show
logflash" command, so I copied the "cisco-nx" device type from
/etc/rancid/rancid.types.base to /etc/rancid/rancid.types.conf under the new
device type name "cisco-nx9k" and removed the command I did not want.

This is how I did it, if you are OK with old-school unixisms...

cd /etc/rancid
gawk 'BEGIN{FS=";";OFS=FS;printf "\n# Same as cisco-nx from
/etc/rancid/rancid.types.base but\n# removing troublesome dir logflash
command\n\n"};/dir
logflash:$/{next};/^cisco-nx/{gsub(/cisco-nx/,"cisco-nx9k");print}'
rancid.types.base >>rancid.types.conf

If you're not gawky :) I recommend you do it by hand instead of the way I
did it.  (Mad props to the maintainer of the FSF's GNU awk, Aharon Robbins!)

Once you've defined the new device type, in your router.db file you use the
newly defined name instead of cisco-nx and you're all set.

Hello,

We are running 3.7

I seem to be having difficulty in getting the command "show dir /all" to
stop be executed with my nexus switches.

I have edited the  'nxrancid'  and the 'nxos.pm'  without success.

Ideas?

-Mike
