    sudo add-apt-repository ppa:freenx-team

  4. Hi, mebigfatguy,

    Here is the guide to add PPA repo:

    Looks like you are using the proxy, you can try the following commands:
    sudo -s
    export http_proxy=
    add-apt-repository ppa:freenx-team

  5. Has anyone gotten remote printing to work? Using FreeNX on ubuntu server at one location, either the Nomachine client or "web companion" at another on XP Pro, and want to be able to allow individual users to print to printers attached to the XP Pro machines and/or network printers on the XP Pro machine lan.....beating my head against the wall so seeing need to make adjustments in node.conf file, but could really use full blown how to including what printer settings would look like.

  6. Hi

    I followed the instructions and installation went without (apparent) hitch. I am using the XP client.

    I cannot connect no matter what I try. I get a connection error with these details :-

    NX> 203 NXSSH running with pid: 232
    NX> 285 Enabling check on switch command
    NX> 285 Enabling skip of SSH config files
    NX> 285 Setting the preferred NX options
    ssh: connect to host port 22: Connection timed out

    I assume that ssh is listening on port 22 as I can PuTTY into it. I can also get in with WinSCP.

    I have looked at a multitude of Google search results, too no avail. Any ideas?

    1. Not sure if you have checked you XP firewall settings. You need to allow client.

      Also, you need to install the ssh key if you have changed the default one.
