[FreeNX-kNX] why is initial authentication/connecting so slow?

You can tail -f the 'sshlog and the 'session' output and check
what's taking so long. Would you be so kind to do that for me?
This is first time I hear about such a slowness problem.

So, how much time does it take to connect with the NoMachine
client when not using SSH/SSL tunneling?

Can it be that the slowness is related to resolving entries
when xauth is run on the client? What exact version of nxclient
are you using (Configure -> Environment -> About)?

Old versions of nxclient were requesting a full list of all
the entries listed in the .Xauthority file, instead of checking
only the right cookie. This required running a name lookup for
each entry, including non-existing hosts. This problem should
have been solved in recent versions.
