[rancid] Citrix NetScaler / nsrancid "Last modified" lines

[Roman Hochuli]

Hello All

I was getting tired to have my logs/mailbox beeing filled up with lines
of this type with every run of rancid:

--snip
- # Last modified by `save config`, Fri Jul 12 13:07:26 2013
+ # Last modified by `save config`, Fri Jul 12 14:07:31 2013
--snap


So I decided to filter out that line. Maybe others would be interested
as well. So here is the diff:

--snip
--- nsrancid 2013-07-12 15:14:06.000000000 +0200
+++ nsrancid 2013-07-12 15:24:34.000000000 +0200
@@ -185,6 +185,9 @@
$_ =~ s/community label .*$/community label <removed>/;
}
}
+ if (/^# Last modified/) {
+ $_ = "";
+ }
return(1) if /(invalid command name)/;
ProcessHistory("","","","$_");
}
--snap

Enjoy.

Actually, I found a slightly quicker way:

Hi Roman,

I for one want to see these "last modified" lines as otherwise I have no
idea when the change occurred -- especially if RANCID is only set to run
once a day or similar and I'm tracking down an issue.

Ideally what would happen is that when a particular syslog line is seen
"commit/saved" etc, then RANCID would run on that device immediately, and
yes, your patch would be a good thing to apply.

Or, as I'm not familiar with that product, could it be that this line is
changing every single time RANCID runs and not just when there has been a
config change?

Cheers,


Matthew Walster
