samba - Oct 2009 - Files copying - date and owner... problems

Hi everyone,

Thank you for reading my post.

I have some data on a "Windows Server 2003" machine I put there 
temporarily (quite a big amount of data: 44.8 GB).

I have copied them back on my Samba server (Debian Lenny hosts the server).

I have had two different types of problems:

1) Date problem:
    ----------------
    some very "old" files which I hadn't touched for an eternity
(or so :))
    have had their date changed to say 2009/10/07 (7th of October 2009, the
    day I copied the data from the Windows to the Lenny server)
    which is not normal and which is very problematic.
    For example:
    - on the Windows server, there is a file <foo.ext> which date is
2007/06/04
    - on the Samba server, after copying it, its date is 2009/10/07.
    (I am talking about the "Date Modified" as it is named on Windows
machines).

2) Owner and owner group problem:
    --------------------------------------
    I was logged as <user1> on the Windows 2003 server.
    <user1> is a Samba user (declared on the Samba server,
    member of the "/etc/samba/smbpasswd" file).
    So, if I understood well the meaning of the Samba config. file:
    normally when a file is copied on the server, its owner is <user1>
    and its owner group is "domadm".
    Some files have had their owner and owner group set to "root"
preventing
    as a result <user1> to write them.

    Here is my "/etc/samba/smb.conf" config. file to check what I said
before:

   
----------------------------------------------------------------------------
    [global]
      workgroup = <workgroup_name>
      server string = %h Samba server
      log level = 1
      log file = /var/log/samba/log.%m
      max log size = 1000
      socket options = TCP_NODELAY IPTOS_LOWDELAY
      logon path       logon home       domain logons = Yes
      os level = 128
      preferred master = Yes
      domain master = Yes
      remote browse sync = yes

    [<share_name>]
      comment = <share_name>
      path = /<share_path>/<share_name>
      force group = domadm
      read only = No
      create mask = 0664
      directory mask = 0775
      guest ok = Yes
   
----------------------------------------------------------------------------

Can you tell me if I misconfigured something?
If I should add someting to my config. file to avoid such problems?
Do you think what happened was a Samba server malfunctioning?

Thank you for your help and all the best,

Hi again,

I am sorry to come back here with my problem but 
I didn't get any response to my previous post...
Maybe my post wasn't clear enough or too long? :)

It is "just" that, when copying files at date D and time T 
from Windows server to Samba server, SOME files times 
(not all of them) have been set to time T and date D.
Which is abnormal isn't it?

I also had SOME files (not all of them) which owner and 
owner group were set to (root, root) instead of 
(current_win_smb_logged_user, forced_smb_conf_group).

Do you think this is because a large amount of files 
were copied? I mean, if this is a Samba bug, isn't it worth 
reporting it?
Do you think I should add something to my config. file?

If you cannot answer don't worry :) I won't post again with 
this topic, I am just trying so see if there is someone around
who would have a little idea...

Thanks for reading and all the best,

That should not make any difference at all. I have done copies in many
different ways and I have never seen this behavior.

Are you using an anti virus program on the linux server? Any chance
some other program windows or linux is accessing these files?

Hi,

Thank you for your answer.

Ok.

No, I have no antivirus program on the Linux server.

Well, no. One of these files for instance was an accountancy archive.
Its owner and owner group were incorrectly set to (root, root).

For that I would enable logging in samba so you with the help of the
mailing list can attempt to debug this.
