Freenx on non standard SSH port not working -- HELP please

[newleonne]

I upgraded to FC5 recently. I used the instructions here
http://fedoranews.org/contributors/rick_stout/freenx/ to set up my freenx and everything works fine with ssh on port 22

I changed my ssh port to 443 for work reasons. I can ssh ok with this port. With freenx I get a connection failure. The error log shows freenx connects and authenticates appropriately on port 443, then tries the launch the session on port 22 before failing. (see below)

I used tried to follow instructions here http://fedoranews.org/contributors/r...enx/freenx.txt about 3/4 way down the page. It mentions to use a non standard port;

Problem:
For added security, I run my SSH server on a non-standard port. How
do I make FreeNX use this port?

Resolution:
Find and following line in /usr/bin/nxserver and change the value to the
needed port:

SSHD_AUTH_PORT="22"

When I open to edit my /usr/bin/nxserver to edit, I do not find the line mentioned above.

Please help me fix this so I can connect to freenx on port 443.

Below is my freenx error log

I figured out how to fix this for those who may run into a similar issue.

Become Super User

$ su
Password:

Change to the nxserver directory that has the config file

# cd /etc/nxserver

Edit the node.conf.sample file

# vi node.conf.sample

Search for the line that reads

#SSHD_PORT=22

Uncomment it and change it to the port that sshd is listening on. In my case port 443

SSHD_PORT=443

Save and close the file

:wq

Copy the node.conf.sample file to node.conf

# cp node.conf.sample node.conf

Restart nxserver

# /usr/bin/nxserver --restart
