[ubuntu-za] Networking

[Jan]

Good morning all,

Could the networking specialists please help?

I am trying to network-connect my Ubuntu 16.04 desktop to my wife's 
Ubuntu 14.04 desktop via the existing ethernet cables that connect both 
machines to the ADSL router.

Both machines pick up ping data from the other, but I cannot get them to 
connect and I get lost when I try to follow these instructions:

My Unity desktop does not have anything that I can find to match 
"Places" referred to in the tutorial in the above link.

Many thanks,

Jan
