[FreeNX-kNX] Session Startup Failed? - Any ideas

Sun Apr 8 21:17:28 UTC 2007

Steve,
You can switch on the debug messages on the ssh server and see what is going
on. (If it is already on, then look in /var/log/secure)
Also check the /var/log/messages to see if the connection was terminated
from the server side.
You can also turn on the nxserver debug messages in your node.conf file
(inside ~nx/etc/node.conf) and give write permissions to
/var/log/nxserver.log to user nx.
To me it looks as if your ssh server is rejecting the user login. Make sure
the username that you are trying to login with is also permitted in the
AllowUsers section of sshd_config file. The way nx works is that first it
authenticates the user nx with the ssh server and then uses user
authentication from the local passwd db.
You should be able to resolve this with the help of debug logs on the
server. If not then post the debug logs to be able to help you further.

Thanks,
Samir
