Proper configuration of samba server and client

Proper configuration of samba server and client

This is how I share directories from my main desktop computer at home running Fedora 23 with another computer I have at home running Lubuntu 14.04 LTS. That is to say, the former acts as server and the latter acts as client. As shown here, I also have a couple of public directories for exchanging files with anyone on the home network.

While configuring samba server and client, I found the official docs
