Samba Client

• To mount a samba share in Linux (see [1]):

$ mkdir -p /windows/winshare
$ mount -t cifs //winmachine/testshare /windows/winshare
$ mount -t cifs -o username=user,password=secret //winmachine/testshare /windows/winshare
$ sudo mount -t cifs -o username=baddreams,allow_utime=22,umask=002,uid=1000,gid=124 //phoenix/D$ /net/phoenix/d

• Or make it an entry in /etc/fstab. Note that gid=124 refers to group sambashare.

//mnemosyne/backup /net/mnemosyne/backuprw	cifs	username=backup,allow_utime=22,umask=002,uid=999,gid=124

Mount as User

To mount a samba share as a regular user (i.e. without sudo), the following conditions must be met:

• /bin/mount, /bin/umount, /sbin/mount.cifs, /sbin/umount.cifs must be setuid (sudo chmod +s ...)
• share point must be owned by the user (chown username mountpoint).
  • May be optional, but does not hurt, set group of mount point to sambashare, and verify that the user is in that group
• mount spec in fstab must contain the option user (or users to let any user unmount).
  • It seems that option suid should be present as well, but does not seem to do anything good to me.

//mnemosyne/public /net/mnemosyne/publicrw	cifs	noauto,users,guest,allow_utime=22,umask=002	0 0
//mnemosyne/public /net/mnemosyne/public	cifs	noauto,users,ro,guest,allow_utime=22,umask=002,suid 	0 0
