No host sits on a special port. Hosts have IP addresses, whereas ports
address a program (service) on a host (ports are the address information
for the application layer).
What you probably mean is: On one of your hosts, sshd is running on
port 80 instead of 22.
You can simply solve this problem by placing the appropriate port
configuration in your .ssh/config file on the connecting host:
Host = some.host.name
Port = 80
This allows you to say "ssh some.host.name" instead of "ssh -p 80
So there's no need to specify the remote ssh port in the hostfile.
