1. NX client connection error
I got remote control progaram NX from nomachine. I installed nxserver to Ubuntu 7.10. and connect with nx client.
There is following message.

Info: Display running with pid '0' and handler '0x54'.

NXPROXY - Version 3.2.0

Copyright (C) 2001, 2007 NoMachine.
See http://www.nomachine.com/ for more information.

Info: Proxy running in client mode with pid '5828'.
Session: Starting session at 'Mon May 26 11:14:32 2008'.
Error: Can't determine the location of the X display socket.
Error: Error 2 'No such file or directory' checking '嗟????덝wE?w????/.X11-unix'.
Session: Session terminated at 'Mon May 26 11:14:32 2008'.
server: ubuntu 7.10 nxserver_3.2.0-7
client: Windows Vista nxclient-3.2.0-10

Until connection is established, operation is fine. but not work for opening session.
maybe I think .X11-unix permission problem.
then I modify permission, still problem is same.

p.s. when I connect nxserver with Ubuntu nxclient, connection is normally.

2. nxmanager is NOT working

browsing http://localhost/nxmanager/
error message is following:

You don't have permission to access /nxmanager/ on this server.
