[OpenAFS] afsd dying on win2k

[Rodney M Dyer]

Mr. Bear,

We've had the same issue here at UNC Charlotte.  We are running Transarc's 
AFS 3.6 v2.32 (Patch 4).  We are seeing random afsd_service.exe crashes on 
our Windows XP machines.  A few of weeks ago we found extensive probing of 
NetBIOS ports from outside our campus gateway.  We disabled the NetBIOS at 
the gateway and the level of AFS crashes went way down.  We still have 
crashes however because we found other probing coming from compromised 
machines within our own network.

This is a bad thing.  We don't want to keep NetBIOS disabled at the router 
because we actually use Microsoft networking in some cases from the 
internet.  In other cases we run Samba servers for access to AFS filespace 
for people who don't use the AFS client.

I posted this same message weeks ago on the list.  A Mr. Scott Williams at 
NC State was also seeing the problem.

 From the looks of it, I don't think anything is going to be done about the 
problem since no one on the OpenAFS group cares anything about 
Windoz...  Since this seems to be the case, we are searching for other 
alternatives to AFS.  I guess I shouldn't be surprised that AFS is so 
unstable on Windoz machines, I mean, it is open source, so you get what you 
get when you get it.  (Yes, I am being sarcastic here about *nix, and open 
source in general.)
