How to edit /etc/fstab properly for network drive?

Each line in the /etc/fstab file contains the following fields separated by spaces or tabs:

file_system    dir    type    options    dump    pass

A typical mount point added in /etc/fstab would look like the following:

# <file system>        <dir>         <type>    <options>             <dump> <pass>
/dev/sda1              /             ext4      defaults,noatime      0      1

You can't simply add a mount statement in the file.

Add this line to the end of your /etc/fstab file:

 //192.168.0.67/test  /home/pi/test  cifs  username=myname,password=123,iocharset=utf8,sec=ntlm  0  0

After the /etc/fstab is edited you can test by mounting the filesystem with mount -a which will check fstab and attempt to mount everything that is present.

In addition to 에이바's answer, you may want to place the credentials in a specific file called .smbcredentials in your home directory for a little more security. This is a good practice especially for multiuser systems. This way you will be protecting your cifs password. Create a file: /home/myname/.smbcredentials and include just two lines:

username=myname
password=123

Set your permissions: $ chmod 600 .smbcredentials

Then in /etc/fstab include the following line:

//192.168.0.67/test  /home/pi/test  cifs  credentials=/home/myname/.smbcredentials,iocharset=utf8,sec=ntlm  0  0

Be sure to test with a reboot.
