[FreeNX-kNX] Multiple problems getting freenx to work, authentication faled for nx user and after re-install nxserver won't start.

[Todd Bateman]

I have been trying for a few days now to get FreeNX installed and setup 
and working but as of so far I have not been able to. If I need to 
remove and re-install it agin it not a problem just tell me what to 
change from what I did. At first I was getting a Authentication failed 
error for the nx user, I googled the error and followed some of the 
directions I found but found things were getting so messed up that I 
removed it and reinstalled it (will include how I removed it and 
installed it at the bottom for those interested). After I reinstalled it 
i executed:

nxsetup --install --setup-nomachine-key
nxserver --start
mv: cannot stat '/usr/NX/home/nx/.ssh/authorized_keys2.disabled': No 
such File or Directory

I take a look and the /usr/NX/home directory is empty the nx/.ssh 
directory didn't get created. I created these directories but no idea 
where I can get this file or get it created and no idea if I have the 
right permissions or the right owner/group on the directories. Also the 
/etc/nxserver directory and files that should be inside it are not being 
created as well as /var/lib/nxserver.

I should say that to be able to set this up I ssh into the linux box 
(Slackware 13/64 bit) and that the system is run headless now that the 
operating system is installed and networking up and I can ssh into the 
box. I used source tarballs to install it. Before I removed freenx I was 
just getting the authentication failed for the nx user (when the 
directories were there and so on) if I tried to ssh into the freenx 
server for the nx user as I have seen suggested as a way to check I 
would get asked for a password.

ssh -p 22222 -i /usr/NX/etc/users.id_dsa.pub nx at localhost
nx at localhost's password <enter>
Permission Denied please try again
nx at localhost's password <enter>
Permission Denied please try again
nx at localhost's password <enter>
Permission Denied (publickey, password, keyboard-interactive)

The /var/log/messages shows this:

Feb 12 12:51:54 krazy sshd[6520]: Invalid user nx from 127.0.0.1
Feb 12 12:51:54 krazy sshd[6520]: Failed none for invalid user nx from 
127.0.0.1 port 49206 ssh2
Feb 12 12:51:56 krazy sshd[6520]: Failed password for invalid user nx 
from 127.0.0.1 port 49206 ssh2
Feb 12 12:51:59 krazy last message repeated 2 times

There is no entry in the /var/log/secure for anything to do with freenx 
at or around the same time.

Here are the steps I took to remove freenx:

nxserver --stop
nxserver --status (to make sure it did stop)
cd /usr/src/nx
rm -r nx*
rm -r freenx*
cd /usr
rm -r NX
rm /var/log/nxserver.log
cd /usr/bin
ls nx*
rm nx*
cd /sbin
rm smbmount
rm smbumount
rm /etc/X11/xdm


Here are the steps I used to install it, it was a 4 page pdf file that I 
found somewhere I can't find the link or name of author to give them 
credit. It was designed to install on Centos 5 using 3.0.0 but I altered 
to work with 3.4.0:
