Hi, I'm trying to change permisions (chmod) or owner (chown) of a file through smbclient conected to a samba server (version: samba-3.0.4-1). I always receive the following error message: Pushing string of 'unlimited' length into non-SMB buffer! hpcinf03:/etc/samba# smbclient //hserint2/HomesUsuarios -U inform Password: Domain=[HGUV] OS=[Unix] Server=[Samba 3.0.4] smb: \> cd bperez smb: \bperez\> chown bperez inf prueba.xls Pushing string of 'unlimited' length into non-SMB buffer! smb: \bperez\> chmod 775 prueba.xls Pushing string of 'unlimited' length into non-SMB buffer! man of smbclient said that these commands depends on the server supporting the CIFS UNIX extensions and will fail if the server does not. By default this command is in smb.conf: unix extensions = yes so I understand it has to work. Do I have to do something to enable CIFS UNIX extensions on my samba server ? Does anyone can give me any clue ?? Thanks in advanced. Grettings, Fernando.
