Simple Samba setup on Lubuntu

I have a simple lubuntu server where I setup a ssh server. While it is sufficient to access a driver/folder from another linux machine using sftp, it is a pain from Windows & Mac, so unfortunately, samba is still needed here. For simplicity I needed only one samba user that I could map to a single user on my lubuntu machine Following the various tutorial I ended up doing this with simple commands Install samba $ sudo apt-get install samba Add myuser to the samba $ sudo smbpasswd -a myuser Export the drive I needed (no guest user) $ sudo vi /etc/samba/smb.conf to add the following export (no real option needed here) [files] path = /media/music/files writeable = yes save and Restart samba $ sudo service smbd restart
