Hello,

Thank you for your reply.

I saw in SWAT that the connection from the other machine was mapped to
the desired local user in all cases (I tried "nobody", "ale" and
"root"). I used "guest account = <user>".

Something strange is happening: I can access the sahre '/mnt' (and
'w2k') with 'smbclient' (using the 'guest' user), but if I do it with
'mount_smbfs //guest at ale/mnt /home/ale/tmp' then the problem appears,
even with 'root' (I can not see/access entries until I list them with
any user from '/mnt/w2k').

I think the problem is with Samba, not 'mount_smbfs'.

This message appears (many times) in debug level 0:

[2005/03/27 15:04:38, 1] smbd/service.c:make_connection_snum(648)
  mariana (192.168.1.1) connect to service mnt initially as user nobody

locking/posix.c:posix_fcntl_lock(659)  on 32 bit NFS mounted file
systems.

The other message I noticed (but I think it is not an error) in level 3
is:

[2005/03/27 14:16:19, 2] auth/auth.c:check_ntlm_password(312)
  check_ntlm_password:  Authentication for user [nobody] -> [nobody]

auth/auth.c:check_ntlm_password(222)  check_ntlm_password:  mapped user
is: [ALE]\[nobody]@[mariana]

The one that also called my attention was:

[2005/03/27 14:16:30, 3] smbd/error.c:error_packet(105)
  error string = Is a directory
[2005/03/27 14:16:30, 3] smbd/error.c:error_packet(129)
  error packet at smbd/nttrans.c(862) cmd=162 (SMBntcreateX)
NT_STATUS_FILE_IS_A_DIRECTORY

However I do not know about the internal working of Samba so perhaps I
missed some important messages.

I made different logs with different debug levels. They are in
ftp://ftp.varnet.to (public FTP) in a directory called "samba_logs". The
local machine is called "ale" and the other "mariana". The best log in
level 3 is in the directory "log.3_2".

Thanks and Best Regards,
Ale
