[FreeNX-kNX] Installing freenx on SLED / SLES 10.2

[Spiro Stathakis]

Hi there ,

I am having problems installing freenx on sles / sled 10.2 and i am
hoping someone can indicate a glaring boo boo i have
made 'cos i cannot spot it ;( . Maybe a 64bit problem maybe a key
problem not sure...we do use ssh keys as our authentication
system and it works without problems (using ssh default settings) so
hoping i can get nx user happy with ssh default settings too.

I have followed the instructions here :
http://mail.kde.org/pipermail/freenx-knx/2007-October/006041.html
Using

nxclient-3.3.0-6.x86_64.tar.gz
nxnode-3.3.0-17.x86_64.tar.gz
nxserver-3.3.0-22.x86_64.tar.gz
and
freenx-server-0.7.3.tar.gz

I then run : /usr/NX/bin/nxsetup --install --setup-nomachine-key --clean --purge

and then....
passwd -d nx

When I run ssh -v -i  /usr/NX/etc/users.id_dsa.pub nx at localhost

i get:

Despite this entry in /etc/ssh/sshd_config:
AuthorizedKeysFile      /usr/NX/etc/users.id_dsa.pub

Another curiosity is /etc/passwd:
nx:x:107:1000::/usr/NX/home/nx:/usr/NX/bin/nxserver

The file system has a /usr/NX/home path but not
/usr/NX/home/nx

I tried creating the folder copying ssh keys into but
nothing doing...

A config check shows :  /usr/NX/bin/nxloadconfig --check

version of FreeNX.

  Errors occured during config check.
  Please correct the configuration file.


Ideally I would like the nx keys to conform the to the rest of the
users on the system who use ssh authentication
with this entry:

 AuthorizedKeysFile    .ssh/authorized_keys


Please will you advise on what I could look at next to get it up and
running....

Cheers !
