samba - Oct 2001 - A bug report

Hi List,

I was using Samba 2.0.7, when I noticed a strange thing:
when mounting samba shares on windows machines, if the window machine crashes 
while I am surfing the mounted FS my linux machine crashes too, completely.

So I updated it to Samba 2.2.1a. I havent checked if this behavior is changed 
yet (I had no time), but I am trying to install a big software package 
(300Mb) via network (I got a Linux Samba PDC). After a while the whole 
network freezes! (and the windows machine freezes too, or course). No ip 
packed is any more sent on the network after that. I got to run "ifconfig 
eth0 down - ifconfig eth0 up" to make it work again. 
This happens all the time.

My network is 10mbit, and during the process of installation gets VERY 
overloaded (lots of collisions). Unfortunately I have not enough money to 
upgrade. However nothing like this happens even if the network is overloaded. 

I am using Suse Kernel 2.4.7, if it is important.

What do you mean by completely? (yes, I have to ask)
Oops? Logfiles? Error messages?

Normally (ie the known bug is that) you get Input/Output errors on all
accesses to the mount when the other end dies. Usually umounting, if
possible, helps.

The process accessing the mount when it dies may block for a long time,
possibly making the machine appear dead. It may of course be so that it
actually did die, but I'd like to know how sure you are.

That sounds more like a problem with the network card/driver.

It means that I cant login anymore. My terminal crashes, and I cant login 
from both my keyboard and the network. It does not reply to ping too.
And nothing appears into logs.

This helps when I am not surfing the mounted windows FS.

Sirs,
A question was arised frorm a friend and I was unable to answer.

How can I enable something in samba that will log the following actions:
1- When a windows machine copies something to the samba server
   what is being copied? filename, lenght etc.
2- When a windows machine DELETES something from the samba share
   filename deleted, user that does the deletion, date.
3- modifications of certain files
   when a windows machine append something to an existing file.
   user that dows the append/overwrite, date.

If this is possible (i really was unable to tell) then we can have a way
to monitor user activities in samba shares.

The question was: If John creates a file in a samba share,
and that share is used by John, Mary and Greg, and Mary deletes
the file (permissions are not the issue here).
 How can I tell that Mary was the one that deleted the
file and the date of deletion, so I dont blame Greg?

Any help will be greatly appreciated.

Thanks in advance,
