====== Ubuntu - Samba - Mount a Windows Share ======


===== Quick Example =====

<code bash>
sudo mount -t cifs -o username=peter,password=xxxxxxxxxxxxxxxxxxxx,uid=peter,gid=peter,forceuid,forcegid,vers=2.1 //192.168.1.5/Docs /home/peter/Documents/nas_docs
</code>

----


===== Command line basic syntax =====

The most basic mount options is:

<code bash>
mount -t cifs -o username=USERNAME,password=PASSWD //192.168.1.88/shares /mnt/share
</code>


----

===== Extended command line mount =====

If the basic mount does not work, you may need to use extended features

<code bash>
mount -t cifs -o username=USERNAME,password=PASSWD,iocharset=utf8,file_mode=0777,dir_mode=0777 //192.168.1.88/shares /mnt/share
</code>

where:

  * **USERNAME** The uid of the user who will own all the files and directories in the share.
  * **PASSWD** the password of the USERNAME user.
  * **iocharset=utf8**
  * **file_mode**
  * **dir_mode**

<WRAP info>
**__FURTHER INFORMATION:__** 

**USERNAME:** By default all the files and directories will be owned by the uid of the process or by root. You can force it otherwise.

<code bash>
sudo id user_name
</code>

If, for example, the user id is 1000 then you can use the following...
<code bash>
uid=1000(user_name) gid=1000(user_name) groups=...
</code>


----

**__dir_mode / file_mode__**

Setting the uid or gid is fine if you are the only user of the system.

On a multiuser system this is problematic as other users will still be denied.

Therefore use **dir_mode / file_mode** to give everyone access:

<code bash>
dir_mode=0777,file_mode=0666
</code>

</WRAP>

----


<code bash>
sudo mount -t cifs -o username=${USER},password=${PASSWORD},uid=$(id -u),gid=$(id -g),forceuid,forcegid, //server-address/folder /mount/path/on/ubuntu
</code>


----



----

===== fstab persistent mount =====

Permanently mount the shares so that they will be available after reboot.

==== Edit the host file ====

Edit your **/etc/hosts** file and add the hostname and IP address of the windows share or file server.

<file bash /etc/hosts>
...
192.168.1.5     NAS
...
</file>

----

==== Create mount points ====

Create mount points for each windows share.  For example:

<code bash>
mkdir /mnt/public
mkdir /mnt/media
mkdir /mnt/video
</code>

----

==== Edit /etc/fstab ====

Edit **/etc/fstab** and add a line for each windows share.  For example:

<file bash /etc/fstab>
//remote_machine/public/ /mnt/public cifs username=peter,password=mypassword,iocharset=utf8,sec=ntlm  0  0
//remote_machine/media/ /mnt/media cifs username=peter,password=mypassword,iocharset=utf8,sec=ntlm  0  0
//remote_machine/video/ /mnt/video cifs username=peter,password=mypassword,iocharset=utf8,sec=ntlm  0  0
</file>

<WRAP info>
** NOTE:** If the system complains add the 'noauto' parameter.

----

=== Mount the shares ===

<code bash>
sudo mount -a
</code>

or Reboot.

----

===== Extended fstab settings =====

Make the following entry in your /etc/fstab file :

<file bash /etc/fstab>
//server_name/share_name /mount_path cifs defaults,uid=1000,gid=1000 0 0
</file>

Now when the share is mounted all files and folders will appear as the user with uid 1000.

**__dir_mode / file_mode__**

Setting the uid or gid is fine if you are the only user of the system.

On a multiuser system this is problematic as other users will still be denied.

Therefore use **dir_mode / file_mode** to give everyone access:


<file bash /etc/fstab>
//server_name/share_name /mount_path cifs defaults,dir_mode=0777,file_mode=0666 0 0
</file>

</WRAP>

----

===== Extende fstab to assign full permissions to newly created files and directories =====

Add these lines to /etc/smb.conf on the server:

<file bash /etc/smb.conf>
...
create mask = 0666
force create mode = 0666
directory mask = 0777
force directory mode = 0777
...
</file>

This gives 0777 permission to every samba users in the write list for new created directory or files.

----

===== Hide Credentials =====

Setup a credentials file so you don't need to enter your password in the command; causing it to be stored in your command history in plain-text) or at the prompt (a nuisance).

<code bash>
sudo mount -t cifs //nas/docs /media/peter/nas_docs -o vers=3.11,credentials=/home/peter/.ssh/.smb_nas
</code>

Note the **credentials option**

<file bash /home/peter/.ssh/.smb_nas>
username=peter
password=[REAL PASSWORD]
domain=WORKGROUP
</file>
