On my previous tutoria, I have posted about how to turn Ubuntu 13.10 into a powerful file server. On that post, I just show you how to install Samba and enable the home directory for every Ubuntu users so they can access their own files over the network. Now I want to show you how to add a new shared folder on Samba file server so any users can store files on that shared folder and work together.
At first, we need to create the directory to be shared
sudo mkdir /share
sudo chmod 777 /share
Now edit the file /etc/samba/smb.conf
sudo nano /etc/samba/smb.conf
Add the following sections to the bottom of the file
comment = ubuntu share
path = /share
read only = No
Now restart Samba
sudo service smbd restart
You are done. Now you will see a new shared folder on your network which can be accessed by any Samba users.
