Making a samba share

• Last tested on Ubuntu 16.04 LTS (xenial) & Windows 10.0.10586

at the end of /etc/samba/smb.conf add a share config.

[ea]
        comment = pistis - echo admin
        path = /var/www/ea
        admin users = mhan
        read only = No
        create mask = 0755

then add the Samba account.

$ sudo smbpasswd -a mhan

then restart samba

$ sudo systemctl restart smbd.service nmbd.service

then on Windows execute the following. For the username, you may have to enter it in the form mhan@pistis or pistis\mhan. Enter the password you used when you added the Samba account for the user.

C:\>net use Z: \\pistis\ea /savecred /persistent:yes
