[FreeNX-kNX] nxsetup

[joel]

I have CentOS 4.1. installed and patched to a fairly current level. I am 
trying to setup remote access via freenx. I can ssh to the CentOS machine 
with no issues and the firewall is disabled while I attempt to get remote 
access functioning. I have spent a good deal of time on google and other 
sites trying to find a definitive approach to how to get this software 
running and have run into several 'approaches'. After a good deal of 
tinkering I am at a stop with the following problem.
I THINK? I need to run nxsetup but after several iterations I am not able to 
get beyond the following scenarios:

IF I use the nxsetup from the original install I get the following reply:

nxsetup --install --setup-nomachine-key --clean --purge
Removing session database ...done
Removing logfile ...done
Removing configuration files ...done
Setting up /etc/nxserver ...done
Generating public/private dsa key pair.

Setting up /var/lib/nxserver/db ...done
Setting up /var/log/nxserver.log ...done
Setting up user nx ...useradd: unknown group -d

In researching the problem I saw a suggestion that a newer nxsetup might help 
so I downloaded a different nxsetup to /tmp. Here is the response to trying 
that script:

[root at localhost tmp]# ./nxsetup --install --setup-nomachine-key --clean 
--purge
Removing session database ...done
Removing logfile ...done
Removing configuration files ...done
Setting up /etc/nxserver ...done

Setting up /var/log/nxserver.log ...done
Setting up user nx ...useradd: group nx exists - if you want to add this user 
to that group, use -g.

I have done a --uninstall previously but I still get the above responses to 
nxsetup. 

These are the original packages that came with the distro. As best as I can 
determine these versions are current and should work. 

freenx-0.4.4-1.centos4
nx-1.5.0-0.centos4

All help apprecitated.
