[rancid] Strange Jerancid/Rancid behavior

[Mack, David A (Dave)]

Oh and btw the bgp neighbor passwords are also fluctuating. So I am going to use the same logic on them as well. You might want to include that with future updates.

Thanks!
Dave

> 	Hello! I am in the process of bringing up a new Rancid server and have run into something with at least the jerancid script for Juniper ERXs. What I am seeing is related to password removal. I have filter passwords globally set to "no". However the ERXs have certain passwords that have their hashes calculated on the fly. So each time they are display the values shown will change. This means you get a new CVS every run. Jerancid has routines to handle two of these conditions for FTP and MPLS LDP passwords:

Does this fix it?
