[rancid] Force10 FTOS 9 still triggering alerts due to flash mod time changing and fan speed

[Vinny.Abello at nttdata.com]

Hello all,

I've got RANCID pointed at various Force10 switches all running some release of OS 9. RANCID continually sees changes from doing a directory listing. This has been discussed before here:

http://www.shrubbery.net/pipermail/rancid-discuss/2013-August/006995.html

It seemed like this was a new issue with OS 9 and a patch was issued to address it. However, I'm running RANCID 3.6.2 and can see in f10rancid that it is patched in this manner, but it seems to have no effect for me. I continually get diffs every time rancid-run fires.

An example:

Additionally, I think it was also mentioned somewhere on this list, some of the output captured includes the RPM reading of the fans in the chassis when checking the power supplies and it is comparing these values which should be ignored.

Here is an example of that:

Is there something I can change in f10rancid to have it ignore these two things and can this be pushed into a future release? I'd be happy to test anything against a myriad of Force10 gear I have.

Thanks!
