Post by Ian StongI'm running an older version of rancid and was wondering if there is
something I can edit to prevent the daily emails for changes I don't care
about as mentioned below. I edited rancid and tried excluding various model
routers giving me the unwanted output (return(1) if ($type =~
/^(12[40]|7|4|2|1)/);) but it didn't change anything
What I had in rancid 2.8:
# This routine parses "show flash"
sub ShowFlash {
# skip if this is 7000, 7200, 7500, or 12000; else we end up with
# redundant data from dir /all slot0:
print STDERR " In ShowFlash: $_" if ($debug);
$redacted = 0; # -LR- set if a file listing is suppressed
while (<INPUT>) {
tr/\015//d;
last if (/^$prompt/);
next if (/^(\s*|\s*$cmd\s*)$/);
### -LR- ideal would be to ignore filesystem changes like date
& time, but I'm not there yet
### -LR- so ignore the whole thing
if (/startup-config\s*$/) {$redacted = 1; next; } # -LR-
if (/private-config\.text\s*$/) {$redacted = 1; next; } # -LR-
if (/config\.text\s*$/) {$redacted = 1; next; } # -LR-
if (/dhcp[-_]database\s*$/) {$redacted = 1; next; } # -LR-
ignore dhcp database changes
if (/dhcp-snooping(-data)?\s*$/){$redacted = 1; next; } # -LR-
ignore dhcp snooping database changes
if (/lic_uom\.dat\s*$/) {$redacted = 1; next; } # -LR-
ignore .private/lic_uom.dat changes
if (/.*\(\d+ bytes (free|used)\)/) { # -LR- want to
show bytes used?
if ($redacted) { next; } # -LR- not
when there are files that haven't been shown
} # -LR-

Lee

Subject: Re: [rancid] excluding output from cisco routers and switches
Post by Alan McKinnonPost by Ian StongHi,
I need to exclude the following output from rancid as it always
Sample below of what it is seeing as a change
- !Flash: bootflash: 273633 drwx 8192 Dec 31 2015 06:27:53
-04:00 tracelogs
+ !Flash: bootflash: 273633 drwx 8192 Dec 31 2015 13:55:48
-04:00 tracelogs
modify the perl code with a suitable regex to detect the line you want
next if /insert some regex here/;
The code is peppered with 10s of examples, and the question has been
asked and answered many times here. It's somewhat of an FAQ.
There already is a filter for this w/ ios-xe, which had a bug in some old
version causing this to endlessly change.
