Hi again,
OK now I did a complete startup after clearing everything also I had to
clear the user nx in /etc/passwd, /etc/shadow and in the two group files
as well. Also I got a resh sshd_config and a fresh ssh_config from a
friend who did not mess it up.
I gave it a next trial with the newest rpms (nx 2.1.0-19.fc6.at-386.rpm
and freenx 0.6.0-12.fc6.at.i386.rpm)
got the athentication --> yipiiieee!!
BUT the session startup failed. OK I googled again enabled loglevel=7
in node.conf, also I activated ENABLE_2_0_0_BACKEND=1 as I am using
the 2.1.0 backend.
Hopefully you can help me with this error ....
The nxserver.log gives following output after some successful logs (at
least some ;-))

Then I activated the SESSION_LOG_CLEAN=0
and session in home/.nx/F-C<session ID>/ gives following error message
(there is no "error"-file):
/usr/libexec/nx/nxagent: error while loading shared libraries:
/usr/lib/nx/libXcomp.so.2: cannot restore segment prot after reloc:
Permission denied
Hm this is the directory:
[root at localhost nx]# ls -l libXc*
-rwxr-xr-x 1 root root 80020 Mar 4 13:03 libXcompext.so.2
-rwxr-xr-x 1 root root 80024 Mar 4 13:03 libXcompext.so.2.1.0
-rwxr-xr-x 1 root root 1108200 Mar 4 13:03 libXcomp.so.2
-rwxr-xr-x 1 root root 1108204 Mar 4 13:03 libXcomp.so.2.1.0
Should I change the permissions? chmod chown? In case it is important
(?): The end of my /var/log/messages looks like the follwing:

Thanks already for all your suggestions up to now. It seems i am getting
closer ....
By the way, NoMachine seems to support shadowing sessions (and also
transfering the actual real display) with there new server version 3.0.
Is there plans to implement such a feature in freenx in the near future
as well?
Thanks a lot
Cheers
Thomas
