This is disappointing
It seems that the issue is the SSH server is not running, is blocked by a firewall or a NAT router. Of course first check that you are using the correct IP address.
The ssh server is running
Check in YaST2 > System > System Services (Runlevel) and make sure SSH is on and running. The firewall setup will be in YaST2> Security and Users > Firewall management and port 22 is what needs to be opened. If it is a NAT router issue, take a look at this site[1].
The firewall is allowing the ssh server service My NAT router (Draytek Vigor 2800v) is redirecting both TCP and UDP traffic on port 22 to my desktop computer's port 22. What next? I'll try switching the firewall off completely... Nah! Didn't work :( Time for bed. See you tomorrow.
Once you get the SSH server running, you can follow the guide[2] to setting up key authentication. Everything should work exactly as published there.
