    Re: HOWTO: Install FreeNX

    freenx is great, 10 times faster than vnc out of ubuntu!

    but, i need to have the same behaviour as vnc. i.e. when I start a vnc session it displays it as display :1 and continues to display on display :0

    so, for what i want, i have display :0 as my tv. and display :1 as the remote window. mirrored.

    there are apparently ways to do this with kde, but how with gnome?

    Please help!

    edit: Ok, well I figured out I can run xvncviewer from within the freenx session... which is a good start, but it would be better if i could just use freenx...

    oh, and i get major image encoding problems unless i set the image to standard bitmaps... is this just me or everyone? i'm using an nvidia mx440

    edit #2 : Well, I've read people talk about using freenx as a proxy to tunnel a vnc connection.... how do I do that? I am using the mac client.... Any help would be appreciated!

    Apparently he changed the repos but never updated the HOWTO:

    New repo should be: deb breezy-seveas freenx

    Re: HOWTO: Install FreeNX

    Hello, I am new to linux and am very familar with Windows. I would like to use FreeNX as a true desktop sharing utility and now start a new x-session. I have KDE installed and both KRFB and X11VNC. How can I set these up to work with FreeNX Server? The FreeNX portion works fine.

    Re: HOWTO: Install FreeNX

    I really like FreeNX. Much better than VNC when working. But there's one critical problem that I'm facing.

    My UBUNTU machine is at my office running 24/7 and I access it via FreeNX from my home WIN XP. My DSL connection using a router is usually stable. But sometimes it drops and my FreeNX session terminates before I have a chance to save my session.

    When I tried to reconnect using FreeNX, I get a new session instead of the resumed one. I can locate the applications running from the existing sessions but how do I restore it?

    This is a major problem for those who work on documents. Any clues?

    Re: HOWTO: Install FreeNX

    i have 2 problems

    1) i've downloaded the freenx client, but i can't connect to my server, i get this error:
    NX> 203 NXSSH running with pid: 3012
    NX> 285 Enabling check on switch command
    NX> 285 Enabling skip of SSH config files
    NX> 200 Connected to address: on port: 22
    NX> 202 Authenticating user: nx
    NX> 208 Using auth method: publickey
    NX> 204 Authentication failed.
    i'm using root to login

    2) is it possible to connect to server using the Remote Desktop Connection that's standard in win XP?

    Re: HOWTO: Install FreeNX

    Ok, I have a silly question but I have to ask it. I got freenx setup and I'm able to connect to it from my windows xp box at work. (Had a time figuring out I had to enable SSL on the NX client) and I get connected. The only problem is that I use Gnome and I can't see the top of my screen using the NX client. Anybody have any ideas?

    Please someone give me a hand with configuration:

    job@UbuntuServer:~$ sudo /etc/init.d/ssh restart
    * Restarting OpenBSD Secure Shell server... /etc/ssh/sshd_config: line 4: Bad configuration option: What
    /etc/ssh/sshd_config: terminating, 1 bad configuration options

    top part of config file with line 4:
    # Package generated configuration file
    # See the sshd(8) manpage for details

    What ports, IPs and protocols we listen for Port 22
    #Use these options to restrict which interfaces/protocols sshd will bind to
    #ListenAddress ::
    Protocol 2
    # HostKeys for protocol version 2
