SSH: does it require portmapper and what hostname is it looking for?

[Anthony Campbell <ac@acampbell.org.uk>]

I'm trying to run ssh between two computers but I get:
	
	"connect to host port 22: Connection refused."

I have portmapper turned off for security, but is it essential for ssh?

Also, what is the hostname I have to supply? The FQDN seems to be
acampbell.org.uk but this is the same for both computers, which doesn't
seem to be right.
