Linux mount CIFS Windows Share

Q. How do I mount CIFS Windows Server / XP / Vista Shared folder under Linux operating systems?

A. Common Internet File System is an application-level network protocol mainly used to provide shared access to files, printers, serial ports, and miscellaneous communications between nodes on a network. You can easily access CIFS share from Linux and mount them as a regular filesystem.

Mount Linux CIFS share

Mount CIFS with the default local filesystem permissions:
# mkdir /mnt/cifs
# mount -t cifs //server-name/share-name /mnt/cifs -o username=shareuser,password=sharepassword,domain=nixcraft
# mount -t cifs // /mnt/cifs -o username=shareuser,password=sharepassword,domain=nixcraft

# mount.cifs // /mnt/cifs -o username=shareuser,password=sharepassword,domain=nixcraft

  • username=shareuser : specifies the CIFS user name.
  • password=sharepassword : specifies the CIFS password. If this option is not given then the environment variable PASSWD is used. If the password is not specified directly or indirectly via an argument to mount, mount will prompt for a password, unless the guest option is specified.
  • domain=nixcraft : sets the domain (workgroup) of the user

    i can mount windows share when using gnome mount.
    but if i use CLI then how to mount without password since there is no password required for my windows share..

      use the guest option.
      help is available from the CLI with:
      man mount.cifs

    Thank you, this article really helped me!

    How can you specify username/pw in /etc/fstab for automatic mounting?

  • Arun Mummidi June 12, 2012, 1:46 pm

    @Drew: You can add a line similar to below to /etc/fstab

    //WindowsHost/Sharename /LocalMountPoint cifs username=,credentials=/etc/cifsauth{any file},domain=[workgroup/WindowsHostName/Most of the time can be left blank] 0 0

    Two zeros at end of line are important as it will prevent boot failure when windows share is unavailable.

    Format of credentials file (/etc/cifsauth)

    thanks a lot.

    …and what if the folder you’re mounting on the windows share has a space in it? //storageserver/old%20work?

  • Arthur December 18, 2013, 9:12 pm

    //storageserver/old\ work

    Just in case a formatting problem crops up, that’s backslash space between old and work.

    Seems some shares requires to use “user” instead of “username” in


    replace username with user like this:

    I have followed the below steps to mount share on debian linux. But i am getting an error as
    “mount error: cifs filesystem not supported by the system
    mount error(19): No such device
    Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

    1. Shard one folder/drive in hyper-v.
    2. Installed cifs-utils on debian linux VM
    3. mount -t cifs //hostname/sharedname localmountpoint -o username=”username”,password=”password”,domain=”domain ”

    The above credentials are hyper-v credentials. Is anything i am missing here?
