samba - May 2005 - Obtaining log level 10 for just specified user(s) (MS Word & Excel File Locking issue - still)

Is it possible to make samba produce a log at level 10 for only a specified
user(s), I am trying (still) to figure out why Samba processes climb to 100%
CPU and the user loses connection with MS Word & Excel files being locked.


Have been dealing with this issue for quite some time now, but had to put it
on the back burner for a while because we had little time to deal with it.
Apprently only an issue with a few users still, yet unable to isolate
anything different from them to the user next to them, aside from filenames,
which are apparently random or not the cause anyhow.

Gave up on trying to fix it a while back, but having more and more problems
daily, with 2-3 processes every hour or so climbing to 100% cpu utilization
and the user being locked out; a simple kill -9 to the process id in
question, and a new one spawns and the end users good to go... Annoying, but
at least a work-around we've been able to get by with. I'd like to get
some
debugging logs, but as these servers are being used in production, I need to
force log level 10 only for specified users (aka ones having the problem).
Is it possible to do this? Log files hit like 5 megs in a matter of a minute
or two; can't accept that for every user on the system - and it's a huge
hit
on I/O we don't need to take either :(

Any suggestions?

I can't address the Word problem, but have you looked at Excel itself as 
the culprit for the Excel problem?  For instance, is the user able to get 
anything done on his/her Excel spreadsheet before this problem 
occurs?  There is a .xlb file (I don't remember its exact name; I'll
have
to look it up when I go in to work tomorrow) that occasionally gets 
corrupted.  Deleting this file makes Excel work OK, again, and the file is 
regenerated the next time the user opens Excel (and is 
changed/updated/whatever MS feels like doing with this sort of file) every 
time the user opens Excel.

In your smb.conf file [global] section put:

	include = /etc/samba/%u.conf

In the file /etc/samba/'username'.conf put:

[global]
	log level = 10


Done!

Actually you've given me an idea. It should be possible to add a "only
these users"
list to the lowest levels of the lib/debug.c code so that only when the
effective id
of the process matches these users will a message get printed. I'm thinking
smbcontrol
may be used to add/unset this list. It wouldn't mean a change in the upper
level
code and you'd just set this list then set the debug level to 10
generically.

Let me work on this some - I may have a patch that applies cleanly to 3.0.14a
and
above....

Jeremy.
