Cifs

Hello

We are using Cifsclient on our HP UX 11.00 machine.

From time to time the cifs agent (cifsclient) seems to stop. all mounts are gone and we need to restart the cifsclient.

After the restart, without any problems, we mount again all drives and it works again.

Anyone can help me out here ?
Is there a special log file to check where i can see whats wrong ?

I've checked the logfile /var/opt/cifsclient/debug/client-log.* . Here i can find the follow messages that repeat a lot:

06-16 18:01:11.598 [0] CIFS Client start; version=A.01.09, pid=22064

We have installed Cifs client A.01.09 (B8724AA) and HP Cifs Server A.01.11 (B8725AA).

Thanx

I have experienced the same problem with 11.11 connecting to Windows NT.

I do it so the nice high capacity tape drive on my HP-9000 server can be used to back up the NT servers critical data.

I have exactly the same results except they are consistent. Every day during the backup connectivity is lost.

At this point I can only think its got something to do with the parameters I'm mounting with or a timeout on the NT side.

Since anything microsoft drives me batty, I am looking into it from the cifsmount side.

It also might be worth filing a software support case because HP might give you insight into what may be done on the NT/Windows 2K Pro side.

No resolution yet, but maybe someone out here can help.

My mount commands:
cifsmount //isnmain.investmenttool.com/shared /isnmain.share -f -I 192.168.0.30
-U root -P password

Yeah, I'm a Geek. I created a root user on the windows side to make my life seem surreal or easier. Take your pick.

Hello

I've tried increasing the timeout parameters on the cifs side. I used the suggested parameters for a "slow network" that i found in the Cifs manual. Still i get lost connections.

I've set the follow parameters
connectTimeout = 30000
requesttimeout = 60000
nfstimeout = 200
nfsretransmit = 5

anyone can help me out here ?
Shoud i start looking at the Win2000 side ?

I suspect window because it is Windows...

When the system gets busy, it will occasionally lose the network connection... Hmm!!! I bet if you have two Unix boxes they don't lose the connections, and takers??? I thought not.

Finding the answer on the windows side may not be easy... I don't think you can tune a windows box...
