[FreeNX-kNX] Server not installed or NX access disabled

Ok, after the 100th reinstall I got it to work.  I
figured it was a key thing, and it seems that the
proper dir's weren't installed with the rpm.  I had to
manually create the dir /var/lib/nxserver/home/.ssh/
and make sure the correct keys got in there, then
those keys had to be copied to /usr/NX/share/keys had
to unlock nx in the passwd using "passwd -u nx" and
tried to ssh using "ssh -i
/usr/NX/share/keys/client.id_dsa.key nx@{NX SERVER}" 
after that it worked.  

Things to note.  When I installed, I got errors:
 
cp: cannot create regular file
`/var/lib/nxserver/home/.ssh/client.id_dsa.key': No
such file or directory
cp: cannot create regular file
`/var/lib/nxserver/home/.ssh/server.id_dsa.pub.key':

/var/lib/nxserver/home/.ssh/known_hosts: No such file

chown: cannot access `/var/lib/nxserver/home': No such
file or directory

It was just a matter of tracking these down.  Maybe a
probem in the install script I dunno, I'm just a
newbie
