Do you have System Preferences -> Sharing -> Remote Login enabled on the destination Mac?
If "Yes", then do you have a system where ssh DOES work? If so, then try 2 ssh diagnostic commands:
ssh -v -v -v DavidSmith@86.138.124.283
ssh -v -v -v username@system.where.ssh.works
Now compare the output from each ssh command, and see where the failing ssh command goes bad. The debugging messages in and around the failure should give you a clue about what is going wrong.
On the destination Mac (86.138.124.283) you can also look in the logs 'sshd' messages. Applications -> Utilities -> Console -> system.log (search for 'sshd')
That is not a valid IP address. Where did you get it from?
There are numerous reasons why the connection may fail.
First - and most obvious - is whether the remote host is actually running and reachable.
Problems here could be related to the IP address being wrong, or a firewall or some other device that's blocking access.
Can you ping the remote IP address? If ping fails then all other bets are likely off.
Assuming the host is up and you're not firewalled, the next question is whether the host is running an SSH server. If it's a Mac, check System Preferences -> Sharing -> Remote Login. Other OSes have different methods of enabling SSH.
Those are the most likely scenarios, and should cover almost all cases. Once you check those you can narrow down the solution.
