Managing SMB Mounts in Your Local Environment (Task Map)

The following table points to the tasks that a regular user can perform to manage SMB mounts.

How to Find Available SMB Shares on a Known File Server

1. Determine the server that you want to query about available shares.

   If you are not familiar with the SMB file servers available in your domain, contact your system administrator. You might be able to use Network Neighborhood on Windows systems or the GNOME file browser to browse for available SMB shares.

2. List the available SMB shares on a server.

   $ smbadm show-shares [-A | -u username] [-t] server

   The -A option enables you to view shares anonymously. You are not prompted for a password. The -u username option indicates the user to authenticate on the specified SMB server. The -t option shows a heading for the output. If neither the -A nor the -u option is specified, the user that is running the command is authenticated on the SMB server.

3. When prompted, enter the password for the user that you specified on the SMB server.

   If you specified the -A option to view shares anonymously, you are not prompted for a password.

   If you did not specify a user, enter the password associated with your user name.

4. View the list of available SMB shares.

   The smbadm show-shares -t output shows the name of the share and an optional text description of the share.

   For example, the following command shows how to view the shares on the solarsystem server:

   $ smbadm show-shares -t solarsystem
   Enter password:
   SHARE            DESCRIPTION
   netlogon    Network Logon Service
   ipc$        Service (Samba Server)
   tmp        Temporary file space
   public        Public Stuff
   ethereal
   root        Home Directories
   6 shares (total=6, read=6)

   The following command enables you to anonymously view the shares on the solarsystem server:

   $ smbadm show-shares -A solarsystem

How to Mount an SMB Share on a Directory You Own

1. Verify that the network/smb/client service is enabled.

   $ svcs network/smb/client
   STATE          STIME    FMRI
   online         19:24:36 svc:/network/smb/client:default

   This service is enabled by default, so the usual state for the service is online. To enable the service, type the following command:

   $ svcadm enable -r network/smb/client

2. Find the share that you want to mount from a server.

   $ smbadm show-shares [-A | -u username] [-t] server

   The -A option enables you to view shares anonymously. You are not prompted for a password. The -u username option indicates the user to authenticate on the specified SMB server. The -t option shows a heading for the output. If neither the -A nor the -u option is specified, the user that is running the command is authenticated on the SMB server.

3. Enter your password at the prompt.
4. Create a mount point on which to mount the share.

   $ mkdir mount-point

   For example, to create a mount point called /tmp/mnt, type:

   $ mkdir /tmp/mnt

5. Perform the mount on your directory.

   $ mount -F smbfs [-o user=username,domain=domain-name,...] //server/share mount-point

   For example, to mount the tmp share from the solarsystem server on the /tmp/mnt mount point, type:

   $ mount -F smbfs //solarsystem/tmp /tmp/mnt

How to View the List of Mounted SMB Shares

This procedure shows how to list all of the SMB shares that are mounted on your system. The resulting list includes your mounts, other users' mounts, and multiuser mounts created by the system administrator.

• List all SMB mounts.

  Use one of the following commands to list the mounted SMB shares:

  • Use the mount command.

    $ mount -v | grep 'type smbfs'
    //solarsystem/tmp on /mnt type smbfs read/write/setuid/devices/dev=5080000
      on Tue Mar 29 11:40:18 2011
    //solarsystem/files on /files type smbfs read/write/setuid/devices/dev=4800000
      on Mon Mar 28 22:17:56 2011

    Note that the mount command includes information about the mount options specified at mount time.

  • Use the df -k -F smbfs command.

    $ df -k -F smbfs
    //solarsystem/tmp      1871312   70864 1800448     4%    /mnt
    //solarsystem/files    8067749    8017 7979055     1%    /files

How to Unmount an SMB Share From a Directory You Own

To successfully unmount a share, you must own the mount point on which the share is mounted.

1. Determine the mount point of the share that you want to unmount.

   Use one of the following commands to find shares that are mounted from an SMB server:

   • Use the mount command.

     $ mount -v | grep 'type smbfs'
     //solarsystem/tmp on /mnt type smbfs read/write/setuid/devices/dev=5080000
       on Tue Mar 29 11:40:18 2011
     //solarsystem/files on /files type smbfs read/write/setuid/devices/dev=4800000
       on Mon Mar 28 22:17:56 2011

   • Use the df -k -F smbfs command.

     $ df -k -F smbfs
     //solarsystem/tmp      1871312   70864 1800448     4%    /mnt
     //solarsystem/files    8067749    8017 7979055     1%    /files

2. Unmount the share by specifying the name of the mount point, /mnt or /files in the previous step.

   For example:

   $ umount /mnt

How to Store an SMB Persistent Password

Interactions with an SMB file server require authentication. For instance, when you view the shares available on a server or you try to mount a share on your system, the transaction is authenticated.

You can supply the password each time that you make a connection to the server, or you can store a persistent password to be automatically used for these transactions.

The password you store persists until the smbadm remove-key command is run for the user.

• Store the persistent password for the SMB server.

  $ smbadm add-key [-u username]

  You can specify the user name as one of the following name types:

  • An isolated name can be a single label, such as terry, or a user principal name (UPN), such as terry@example.com.

  • A composite name includes the domain name, which can be a host name. A composite name uses one of these formats: domain\username, domain/username, or username@domain.

  The following command stores the persistent password for terry@solarsystem. Each time Terry performs a transaction with solarsystem, the persistent password is used to perform the authentication.

  $ smbadm add-key -u terry@solarsystem
  Password for SOLARSYSTEM/terry:

How to Configure the PAM Module to Store an SMB Persistent Password

When installed, the pam_smbfs_login.so.1 module enables you to store a persistent password as if you had run the smbadm add-key command for PAM_USER in the user's or system's default domain.

This optional functionality is meant to be used only in environments that do not run AD or Kerberos, but which synchronize passwords between Oracle Solaris clients and their SMB servers.

For more information, see the pam_smbfs_login(5) man page.

• Use your login name and password to store a persistent password.

  Add the following line to the /etc/pam.conf file after the other login entries:

  login   auth optional           pam_smbfs_login.so.1

  This action adds a persistent password entry as if you had run the smbadm add-key command.

  ---

  Note - The PAM module implements a privilege to permit it to run as superuser to store your password.

How to Delete an SMB Persistent Password

Use this procedure to delete persistent passwords that are stored by the smbadm add-key command.

• Delete one or more persistent passwords for the specified user by doing one of the following:
  • To delete a single persistent password that was created by the user running the smbadm remove-key command, type:

    $ smbadm remove-key -u username

    For example, the following command removes the persistent password for terry@solarsystem:

    $ smbadm remove-key -u terry@solarsystem

  • To delete all persistent passwords that were created by the user running the smbadm remove-key command, type:

    $ smbadm remove-key

    For example, when user dana runs the command, he removes all of the persistent passwords that he created. After the passwords are deleted, the user is prompted for a password each time that he or she performs an SMB transaction.
