what do i have to do to use NX on a different port than 22 (SSH)

  • 772

I have installed OpenSSH server on my Ubuntu Linux box (10.04). I can SSH to the box properly, no problem. I have to use port 443/TCP. No problem accessing a shell prompt with PuTTY or other SSH client. Hoewver, when I try to use NX to have a graphical session, it is not responding. I thought that NX is simply using the settings used by /etc/ssh/sshd_config. Are there other parameters for NX that I should change so that it listens on port 443 ?

I use NX from nomachine.com, and the version of all components is: 3.4.0-5

Thanks :-)

configuration ssh nx

    On the commercial NX, edit /usr/NX/etc/server.cfg, change SSHDPort, and restart NX.

    (A little more... I like to link the NX etc directory.)

    ln -s /usr/NX/etc /etc/nx
sudo vim /etc/nx/server.cfg

    Change SSHDPort and save.

    /etc/init.d/nxserver restart

  2. If you are using FreeNX, you will need to edit /etc/nxserver/node.conf. In the General FreeNX Directives, locate this lines:

    # The port number where local 'sshd' is listening.
#SSHD_PORT=22

    Uncomment the second one and put there the port where sshd is listening. Note that I haven't been able to test it, so please comment if it doesn't work.

  3. Looks like there should be some sort of GUI configurator available in the programs menu.

    It also looks like there's a wizard you can run on the command line with

    nxclient --wizard
