Topic: smbd error logs? Failure to read file and directories

[pjwallis]

I am running esmith 5.6 unsupported in a network environment with XP Pro. There are lots of occasional errors where the files or directories are not available from the client machines.

The SMBD log contains lots of entries some are included below. I have searched the manuals and checked on the net and now would appreciate some help in reading and understanding the Logs for Samba.

Peter,

Check your network (network-cabling)
...definitely if you are running 10Mbit Coax or hub not switch...
The errors you see may all be attributed to failure of network communication with the XP machine!

I am using Cat 5 with switches and NO hubs. I have recently installed new switches and cabling into the business and it was a clean install at the time.

Peter,

Since your problems do come from communication failures,
- check the server network card,
- check each xp-client connection (by data transfer and looking for errors)

I do know too little about your lan but
if the speed difference of the PCs involved is very large you might try (as a kludge) to disable locking:
- ssh into the server
pico /etc/smb.conf
change:
oplocks = true
into
oplocks = false

In any case your XP side (from the server nic on) is not answering in time in the samples you show.

Regards
Reinhold

Thanks Reinhold for the suggestion - I will give it a go.

Do you or anyone know where I can find the information to understand the smbd logs?

Thanks for all you help
Yours sincerely,
Peter Wallis

Peter,

I can recommend my (older) copy of "Using Samba" from O'Reilly which is quite helpful in tracing Samba problems.
It's probably not that detailed on the log you gave but as most O'Reilly books you may read it (at least in part) online. Here's a quick link:
http://www.oreilly.com/catalog/samba/chapter/book/ch09_01.html


Have you tried to increase die smbd -d  "debug level" ?

Regards
Reinhold

Are you running mirrored drives and is one malfunctioning or unhooked?

Hi,
Thanks Reinhold for the tips on removing oplocks. Have done that and no apparent errors yet. Tomorrow will be a real test of the system.
The accounting software this place is running specifically states that oplocks should be turned OFF, and now they are.



I am also starting to get a picture that one of the switches in the network may have a faulty port and it has been removed to see if the high numbers of fragments, collisions, droppkt, and RXbad dissappear.

Thanks for all your help.
