[FreeNX-kNX] No /usr/NX directory after "yum install freenx"

[Thomas Pfrommer]

Hi freenx communty,
finally I solved the authentication problem ... see previous thread ... 
I had to comment

#AuthorizedKeysFile   .ssh/authorized_keys2


in sshd_config and then I could at least connect to the server, however 
the session was right away closed, as no file /usr/NX/ ... was found. Hm 
it was not there!! Also strangely,  I couldn't find any nxserver 
application file.

I did uninstall everything before and started from scratch, this time 
with yum install freenx, which takes care of installing nx before. I 
have the feeling, that I read somewhere in the last days that nxclient 
from No Machine should be installed instead of the nx ... but cannot 
remember and cannot find it any more. Hm But installing nxclient, and 
then trying to install freenx  (this time with rpm -ivh freenx..... ) 
won't work either as freenx needs as dependency nx and not nxclient.
Should I first install nx and freenx and then nxclient? How do I 
proceed. I am running FC6 with the 2.6.20 Kernel.
Thanks a lot for your help so far and perhaps for the next steps !
