set your log file to logdir/%U_on_%m_from_%m.log, and see if you're
getting oplock errors in that log.



Hi Christopher,

Thanks for taking an interest.

I've done as you suggested  so far as I can tell am not seeing oplock 
errors.

Trying to open file Book1.xls from computer name echelon as user 
dee I see the following in dee_on_echelon_from_echelon.log:

Additionally, in the preceding 4 seconds there are 12 messages in this

Not knowing what these files are describing I cannot comment as to what 
this shows beyond noticing/guessing that a read/write lock seems to have 
been granted, on the requested file, according on the to the 'nobody...' 
log while the windows system appears not to have write access on this 
file.

[Samba] Intermittent problem with samba win2k

2002-11-16 Thread dave cunningham 
I'm new to linux  samba having just started using each within the last
month or so.

I have a small LAN at home consisting of 2 win2k machines and a samba
file server (2.2.6) on a SuSE 7.3 box.

I'm seeing intermittent problems accessing a samba share from each of
the two win2k machines and would appreciate any help in solving this.

What I see is problems creating a new file or opening an excel file on
the server. There seems to be no problems at all in opening read only
files.

A typical error in creating a file through explorer on a win2k machine
is 'fileName' cannot be accessed. The file may be read only, or you may
be trying to access a read-only location. Or the server the document
is stored on may not be responding

 the error I see in opening an excel file reads
'fileName' cannot be accessed. The file may be read only, or you may
be trying to access a read-only location. Or the server the document
is stored on may not be responding.

This seems to happen randomly from either win2k machine and the problem
will sometimes disappear and at other times require smb to be restarted
to see a resolution.

I have 2 trace files available logging this behaviour however I don't
understand what they are showing.

The first (level 3) is here http://www.upsilon.org.uk/temp/log.smbd
shows a user opening excel file 'BOR - Donegall Road Timetable.xls'
being presented with the 'cancel/retry' message  selecting retry a
number of times.

The second (level 6) is here
http://www.upsilon.org.uk/temp/log.smbd.gz and shows a user attempting
to open excel file 'ITT Financial Statement (version1)(version 1).xls'
being presented with the same 'cancel/retry' message and selecting retry
one time.

It was suggested that this may be being caused by DNS issues - initially
I had no DNS server running on the LAN. In an attempt to remedy the
problem (unsuccessful), I set up a DNS server. Thus the first trace file
is for the LAN without DNS (though with hosts/lmhosts configured
correctly - I hope), the second is for the LAN with a DNS server.

Additionally, the when the first trace was taken the win2k boxes were
running SP2, for the second they have been transitioned to SP3.

I've been trying to get to the bottom of this for a few weeks now 
would appreciated any help at all.

My smb.conf files is as follows:

[global]
workgroup = WEELAN
netbios name = MINI
server string =

username map = /etc/samba/users.map
syslog = 0
