I added your last 2 lines to my ssh_config but no luck.

Can I assume that port 22 is open on the other computer to receive ssh 
if it can send through ssh?

I have been trying a lot of changes to various networking files. After a 
change is all I need to do is restart /etc/init.d/ssh  or networking?

Thanks for you help Andreas
