How to mount.cifs for writing in home network

  • 772

I need to mount a directory /home/MyUser/Share to another computer as an equivalent to smb://IP_address/share that enables me writing into files there via Nautilus.

Even for MyUser being a sudoer, my attempts 

sudo mount -t cifs //IP_address/share /home/MyUser/Share -o username=User_at_IP_address,noexec<

or

sudo mount.cifs //IP_address/share /home/MyUser/Share -rw

enable reading only and

sudo mount --make-shared /home/MyUser/Share

does not enable writing, too.

A standard user can use pkexec instead of sudo or change his account via the su command, but the problem with user rights to write is then even greater.
Please advise me the correct steps. Thanks!

  1. I use

    sudo mount -t cifs -o credentials=/root/.credentials,uid=myusernameonclient,gid=users //IP_address_share /home/myusername/mountpoint

    I think this: uid=myusernameonclient,gid=users is what you will need to change. The .credential file includes

    username=myusernameOntheserver
password=mypasswordtoaccesstheshare
domain=thedomainname

    You will not need that, if you access the share without credentials.

  2. Firstly test it:

    $ sudo mount.cifs //your_server/share ~/local_dir -o user=domainUserName,dom=domainName,pass=yourPassword

    Check the result:

    $ ls -l ~/local_dir

drwxr-xr-x 2 root root 0 ago 30 08:09 local_dir

    Note that the problem is the local_dir owner and group (root). Your user and group needed to be there, right? Let's fix it:

    $ sudo umount ~/local_dir

    And the final solution:

    $ sudo mount.cifs //your_server/share ~/local_dir -o user=domainUserName,dom=domainName,pass=yourPassword,rw,uid=yourLocalLinuxUser,uid=yourLocalLinuxGroup

$ ls -l ~/local_dir

drwxr-xr-x 2 localUser localGrp 0 ago 30 08:09 local_dir

    Test with:

    $ touch ~/local_dir/testFile.txt

  3. Add this line to your fstab with sudo nano /etc/fstab:

    //IP_address/share /mnt/Share cifs credentials=/home/MyUser/.credentials,iocharset=utf8,sec=ntlm,uid=1000 0 0

    To create the credentials nano /home/MyUser/.credentials:

    username=MyUser
password=MyPassword

    And change the permissions so only you can read that file:

    sudo chmod 600 /home/MyUser.credentials
