[rancid] Unable to Conduct Cisco Wireless Controller Backup

[Piegorsch, Weylin William]

Hi Heasley,

I was finally able to try this out.  Actually - more specifically, I tried the same command on this WISM2 that I tried a moment ago on the WLC 8540, and got 100% identical results. I don’t think this issue is in catching the logout, though if you want me to I can try your patch below.

    Thanks for the patch.  I can’t test today, but I'll try it out tomorrow or Wednesday.  If it doesn’t work, I'll also try with -d and NOPIPE=yes... forgot about that until now.

        > I’m running rancid v3.4.1.  I have a number of Cisco WISM2 controller running 8.2.166.0.  rancid is not able to acquire any of their configs.  I’ve tried various types in router.db: cisco-wlc4, cisco-wlc5, and cisco, none of them work. The logs, copied below, show the results of cisco-wlc5 (all controllers were identical, I’ve trimmed down to just one).  What could be causing this?  Why would the results vary across the five rounds?  And, which type should I be using?

        does the patch below fix it?  the patch is against HEAD, so there
        may be some fuzz.
