[ubuntu-uk] Sharing files and folders between two 14.04 machines

[Gordon Burgess-Parker]

Two 14.04 machines on the same LAN.
I am having THE MOST ridiculous time trying to share files and folders 
across the LAN between these two machines.
I've installed Samba on each machine - won't connect.
I've tried installing ssh server and client on each machine, when I 
choose "connect to server" it won't browse, and if I put the IP address 
of the other machine in, the "connect" button is greyed out.

How DIFFICULT can it be to share files and folders between two Ubuntu 
14.04 machines on the same LAN?
Grrrrrrrrr!
