[rancid] Re: cisco syslog diff

Tue Aug 18 16:12:02 UTC 2009

Hi

I have the same problem, after an IOS upgrade on a 7609 router, 
resulting in annoying 5-minutely diff mails, so I made the following 
adjustment to the ShowLash() subroutine in bin/rancid:

---
while (<INPUT>) {
tr/\015//d;
last if (/^$prompt/);
----> last if (/Flash/);
next if (/^(\s*|\s*$cmd\s*)$/);
return(1) if ($type =~ /^(12[40]|7)/);
return(-1) if (/command authorization failed/i);
return(1) if /^\s*\^\s*$/;
return(1) if /(Invalid input detected|Type help or )/;
# the pager can not be disabled per-session on the PIX
s/^<-+ More -+>\s*//;
/\s+vlan\.dat$/ && next;
ProcessHistory("FLASH","","","!Flash: $_");
}
---

Is this the correct way to do this? Will this result in a loss of 
information that I might need to determine IOS version changes between 
upgrades?

Thanks,
Traiano
