[rancid] stopping command from being run

[Charles T. Brooks]

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
