[rancid] persistent alerts - but nothing was changed ... ?

Post by Wilkinson, Alex
Hi all,
I am consistently getting rancid alerts (diffs) that config has changed on
a number of Cisco Nexus devices. However, the diffs in the email are exactly
the same each rancid-run(1) and are bogus.
Is there anything that would cause rancid to see bogus diffs ?

A diff is a diff, and it has content because something is different.
Maybe whitespace.

If you post one of these diffs, we can help examine it for you.

I'm using SVN not CVS.

Here is an example diff - I have not touched these lines whatsoever but get alerts every day about them:

I don't know the box but the diff seems to indicate that the location of
mgmt0 and mgmt1 interfaces in the config file is changing. In the first
diff the interfaces are before Ethernet1/1 and in the second diff, they
are after Ethernet 1/20

You are exactly right. When comparing the diffs via OpenGrok its very clear that
the line locations consistently change causing a diff + rancid alert. If i'm not
changing these devices and the line locations are supposedly changing - what
could cause this ? rancid ?

Something I have noticed is that for all my Nexus devices (7K, 5K, 4K) none of
them have the 'RANCID-CONTENT-TYPE' of 'cisco-nx' but rather plain old 'cisco'.
Could this be the reason behind the my problem ? And even if not, why would
Rancid not be using cisco-nx automagically ? Or do I have to set it manually ?

Ah, great! I changed all NX devices to cisco-nx. This seems to fix the false alert
noise but now introduces a new problem for our Nexus 5000s e.g

Trying to get all of the configs.
nexus5k1-1: missed cmd(s): show cores vdc-all,show processes log vdc-all,show running-config
nexus5k1-1: End of run not found
!
nexus5k1-2: missed cmd(s): show cores vdc-all,show processes log vdc-all,show running-config
nexus5k1-2: End of run not found
!
nexus5k2-2: missed cmd(s): show cores vdc-all,show processes log vdc-all,show running-config
nexus5k2-2: End of run not found
!
nexus5k2-1: missed cmd(s): show cores vdc-all,show processes log vdc-all,show running-config
nexus5k2-1: End of run not found

All other Nexus devices work fine now (7Ks, 4Ks).

Any ideas ?

The failing commands are the last three, so I'd suspect the command just
before those - show debug.

Stuff to check:

1. Does clogin properly work and properly enable the login?
2. What is in the log files (${RANCIDDIR}/var/logs/*) for those devices?
3. Does the rancid user have proper permissions to run those commands?
(keep in mind that if you use tacacs for auth, that Nexus are *very*
different from IOS wrt authorization).

I found that the default behaviour in the nxrancid code was to quit the
script entirely on permission denied errors, which caused me huge
issues. So now I apply this patch (beware, it's long):

(my notes about what it does):
* The nexus parser is incomplete and "Permission denied" errors cause
the parser to fail and quit. We want to continue regardless and mark the
command as having failed.
* Oddly enough, "show fex" and "show module fex" are not supported out
of the box.
* Oddly enough, the routine to sanitize SNMP community strings is
commented out.
* Changed the code to redact tacacs keys
* Expanded password redaction regex to exclude "mpls ldp neighbor"

it wouldnt be rancid, it's the device itself. report the bug to the TAC.

You have to set it manually in router.db
Rancid has no auto-detection of device type

Totally untested/pulled out of somewhere or other but diff (or svn diff,
dunno about cvs diff) can take a -b flag that ignores changes in the
amount of white space.
A very brief grep in the /usr/libexec/rancid/* scripts (on a centos
install not sure where for other distros/OS) leads me to think you could
try adding the -b flag to the relevent diff commands in control_rancid.

Cant promise this will fix it or is a good idea but it could work.

I see TONS of buggy outputs that cause this same behavior from our Nexus
boxes.

It's almost entirely due to whitespace changes in outputs.

You'd seriously think that the output of something like show commands
would be consistent...but I guess that's too hard to do. ;o)

A diff is a diff, and it has content because something is different.
Maybe whitespace.
If you post one of these diffs, we can help examine it for you.

Odd, I don't have many issues. On the subject of white space, I believe it
was John Jetmore who proposed this white space fix, is it in your code?

ShowEnvPower currently looks like this (from Zenon Mousmoulas/myself), which
I hope fixes the problem for folks:
