Linux as a Client to Windows SMB Shares

Linux as a Client to Windows SMB Shares

This article briefly explains how to access Windows SMB shares in Linux. Linux is a client here.

If you want to read about using Linux as a Samba server to serve files to Windows clients, see Samba Quickstart.

Quick Mini-HOWTO

This chapter contains just the required commands without any additional testing.

Here, we want to connect to smb://windowsuser:windowspassword@windowsserver/share (workgroup WINDOWSGANG), so we have:

  • Windows Server: “windowsserver”
  • Windows Share: “share”
  • Windows Username: “windowsuser”
  • Windows Password: “windowspassword”
  • Windows Workgroup: “WINDOWSGANG”
  • Linux User: “linuxboy”
  • Linux Group (for user linuxboy): “linuxboy”
  • Mount Point (an empty directory): “mymountpoint”

Edit $HOME/sambapass (here: /home/linuxboy/sambapass)

# $HOME/sambapass
username = windowsuser
password = windowspassword
domain   = WINDOWSGANG

Create an empty directory (a mount point):

$ mkdir $HOME/mymountpoint/

As root, edit /etc/fstab, add this line in the end:

//windowsserver/share /home/tee/mymountpoint
 smbfs
 credentials=/home/tee/sambapass,uid=linuxboy,gid=linuxboy,dmask=700,fmask=700
 0       0

Put the above in a single line, I’ve splitted it only for readability. In options (credentials…fmask=700) there are no spaces. Numbers are zeros.

Then, as root, mount all mounts mentioned in fstab:

# mount -a

Mount often warns you a couple of times about “session request to windowsserver failed (Called name not present)”, but with ls you can see that the directory was mounted.

Test is as normal user (here: linuxboy)

$ touch $HOME/mymountpoint/tero.txt
$ ls $HOME/mymountpoint/
tero.txt

Well done, you have mounted a windows share to Linux using just command line. If you ever have to reboot, it will be automatically mounted again.


Step-by-Step Process for Troubleshooting

If the above worked for you, good. No need to read more, unless you want to learn troubleshooting.

mount: wrong fs type, bad option, bad superblock on

       In some cases useful info is found in syslog - try

(=> smbfs not installed)
$ sudo apt-get install smbfs
$ sudo mount -t smbfs -o credentials=/home/tee/sambapass //172.28.1.133/tero /home/tee/teroghettoy/

//172.28.1.133/tero on /home/tee/teroghettoy type smbfs (rw)
$ sudo umount teroghettoy/
$ sudo umount teroghettoy/
umount: teroghettoy/: not mounted

Now writing works.

$ sudo mount -a
$ mount |grep teroghettoy
