I'm not sure I know what you mean.

What is a ssh log? A normal system log that logs ssh connections?
There's only normal stuff in it.

What is the session output?

When I use NoMachine nxclient, there is no session output (or I don't 
know how to enable it). As I noticed, there is only output when 
connection failed etc.

It's long (> 1 minute) either I use ssh/SSL tunneling or not.

I don't know?
How to check it?
What "resolving entries" do you refer to?

It's nxclient-1.4.0-91, downloaded from www.nomachine.com, for Mandrake.

I have a newest version possible, so this shouldn't be a case.
