[rancid] rancid finding changes that do not exist

[Jason Humes]

Hi

This is a Cisco 1800 IOS router/firewall configured in router.db as a 'cisco'.  The version of RANCID is;

rancid at Netmon-Backup:~$ bin/rancid -V
rancid 3.1

I'm not sure what is meant by maybe the device is doing it...doing what?  The diff is done by rancid, the router just does outputs the response of 'show' commands, no?

Thanks

Jason

Hi
We've got some devices that rancid thinks have changed but have not, for example;

The line;

+ ip nat inside source static tcp 142.46.14.24 21 interface
+ FastEthernet0/0 21

Is actually;
ip nat inside source static tcp 142.46.14.24 21 interface FastEthernet0/0 21

Which rancid says was remvoed (-ip nat inside source static tcp 142.46.14.24 21 interface FastEthernet0/0 21)

Any idea why it is parsing the text like this?
