Check SMB-Connections (Resources in use?)
Hi,

is it possible to check smb-connections of my server? I want to see, which files are opened from which station (ip).

The command who only works local (via terminal).

Regards.

Code:
root@isau02:/data/tmp/testfeld> netstat -an| grep -iE ":139 |:445 "
tcp        0      0 0.0.0.0:139             0.0.0.0:*               LISTEN
tcp        0      0 0.0.0.0:445             0.0.0.0:*               LISTEN
tcp        0      0 10.10.10.86:445        11.11.11.23:3246       VERBUNDEN

I guess you will have no luck to see which files they use. I doubt you can make Samba that talkative in debug levels. But maybe check the documentation for it.

Thank you
Hello zaxxon,

Thank you for your fast reply.

I found out that the command smbstatus will give information about opended connections and used files (LOCK).

I think this is the right way. But the output of smbstatus is not what I prefer. An output like this would be nice:

Code:
------------------------------------------------------------------------
IP                      RESOURCE                                TIME
192.168.1.40       /data/share/presentation.pps       connected since 10m
192.168.1.52       /data/share/text.txt                   connected since 2m
192.168.1.60       /data/share/movies/sample.mov   connected since 1h
------------------------------------------------------------------------

I think this topic should be moved in Shell Programming and Scripting.

Hope anyone can help me. :-)

Thanks again and best regards.

You should not only post how it should look like ie. what you want but also how the input ie. the output of smbstatus looks like because maybe not all people that want to help you have such output available.

I move your post to Shell Programming and Scripting.

@ zaxxon

Sorry for this. Here is the addition.

This is the output of smbstatus -L to list all LOCKED (opened) files:

Code:
Locked files:
Pid          Uid        DenyMode   Access      R/W        Oplock           SharePath   Name   Time
--------------------------------------------------------------------------------------------------
6482         503        DENY_NONE  0x100001    RDONLY     NONE             /data/share/dir01/  .         Mon Dec  8 10:32:43 2008
6482         503        DENY_NONE  0x100001    RDONLY     NONE             /data/shares/dir01/test.mov   Mon Dec  8 10:32:45 2008

Now I need the proper IP-addresses. With the Pid you can find out which IP is used. The command is smbstatus -S:

Code:
Service      pid     machine       Connected at

No I need a script to compare these two outputs, so that I get a list like this:

Code:
------------------------------------------------------------------------
IP                      RESOURCE                                TIME
192.168.1.40        /data/share/presentation.pps    connected since ??m
192.168.1.52        /data/share/text.txt            connected since ??m
192.168.1.100       /data/share/movies/test.mov     connected since ??h
------------------------------------------------------------------------

It's important to weed out duplicates (users that are connected to several samba shares).

I found an article with a similar problem, but I have no idea about shell-scripts. So I hope anyone can help me an this Link is helpful.

Thanks and regards.
