After a little digging, I found that there is no .Xauthority file in the /home/user/ directory. Is there something I can do to create it? Help would be greatly appreciated.

thanks,
Bruce

I’ve only dabbled a little bit with NoMachine, but I have found that the client machine’s Desktop manager is a factor: what OS and window manager is running at your “location B”?

Try re-install NX Server.

Been out for a while. Thanks for the response. I removed nomachine, deleted the /usr/NX & /home/username/.nx dir, removed the nx user and installed freenx on pc at location A (suse 11.2) I was able to connect fine. But when I removed freenx and reinstalled nomachine nxclient, node and server in the correct order, generated a key, paste the key into the client pc at location B (also suse 11.2) I get the same error message again. After that I installed nxnode and nxserver on the pc at location B wich already has nx client installed and was ablet to connect to it with a third computer (laptop w/suse 11.0) using instructions above. And pc at location A now has /home/username/.Xauthority file with username:usr as owner. freenx won’t work because I need the abillity to share the same desktop to help out my Mom who lives to far to drive. thanks again.

Never mind!
All I had to do was read the error message in /var/log/messages. You know. The part that says “Bad display name”. So I added the host name of the server in the server’s /etc/hosts file and its working. Thanks anyway.
Bruce.

Thank youuuuuuuuuuu!!

What an unbelievable hassle, had Nomachine up & running in minutes with Gnome, and then server reboot broke installation, 5 hours of futile searching.

Updating /etc/hosts did the trick.

I love/hate linux ;–)

Its pretty old but want to say thanks a bunch for hint anyway.
I had 2 identical installs of sles 11.3, at least i thought i had. Turns out, after your advice, i remembered that in one of VM’s i neglected to check “Add hostname to hosts file” during install.
doh, im older by 2 hours again, dangit :confused:
