3. Grab a Freenx package
   1. Use this package for FC2, FC3, FC4, and xorg based distributions

      • #wget http://fedoranews.org/contributors/rick_stout/freenx/freenx-0.4.4-2.fdr.0.noarch.rpm

   2. Use this package for FC1, RH9, RHEL3 or XFree86 based distributions

Configuration after Installation

1. Since package installation successful, need to setup nx for FreeNX running

   • set PATH including /usr/libexec/nx, in order that file nxloadconfig is searchable during setup

   • locate nxsetup file, and run it as root

     • #/PATH/TO/nxsetup
2. Configuration files location:

• node.conf.sample

  passwords.orig

  passwords

  server.id_dsa.pub.key

  client.id_dsa.key

  users.id_dsa.pub

  users.id_dsa

• For FreeNX versions >=0.5.0 you might need to edit the file /etc/nxserver/node.conf

• copy node.conf configuration file from sample

  • #cp -p node.conf.sample node.conf

• Then edit file node.conf correspondingly, comment out the following lines, and edit similar as shown:

  1. DISPLAY_BASE=4000
  2. SESSION_LIMIT=200
  3. SESSION_USER_LIMIT=200
  4. DISPLAY_LIMIT=200

  8. USER_X_STARTUP_SCRIPT=.Xclients

1. Every time after edit configuration file node.conf, restart nxserver:

   • #nxserver --restart

2. Before nxclient is able to connect with nxserver, need to copy the PRIVATE KEY to client side for ssh authentication purpose.

   • The file is located at /etc/nxserver/client.id_dsa.key
