NX software for graphical remote access to linux is available for login to the following server:

  • nx.uib.no

The NX software is a free (nxclient), more effective and easy configurable alternative to xwin-32, VNC, VNC-SSH and similar products, with software accelerated OpenGL support. All data transmission are encrypted and include remote graphical access (X.org) to linux computers also from external networks. The installation consists of two steps.

  1. Download and install the NX client
  2. Configure the client and add the server-key

Installation of the NX Client for Windows

Download the NX client software from the following site:

From a windows computer where you dispose an administrative account, run the downloaded *.exe file to install the NX client software. (There are also available free client software for mac, linux and solaris.)

Configuration of the NX client

Start up "NX Client for Windows" from the windows Programs menu. Until it is configured, the NX Connection Wizard will guide you through the following where you fill in the correct information found in figures below.

The session window:

From the Desktop window, remember "Enable SSL" and you may prefer a "gnome desktop":

or you may rather prefer a simple xterm window enabled by this combination:

The last important steps include selecting the "Advanced Configuration" dialog from:

From the "Advanced setup" menu, click the "Key" button:

The following window will appear:

In this window, remove your current DSA-Key and import the following by "copy-and-paste" from below:

You may also wish to select "Norwegian layout" of the keyboard:

Then click the Save button and the OK button to proceed to the login screen where you add your userid and password. If login fails, please check all setup again - when working you may fine tune your preferenced settings. That should be all!

Some versions of nx-client lack the "Keyboard custom" entry. You then select keyboard layout from inside GNOME/KDE (gnome-keyboard-properties), or you select "Run the default X client script on server" when customizing desktop (see above) and place something like this in your ~/.xsession file:

setxkbmap no
/usr/bin/xterm

UiB ITA now runs the "NX Server for Linux" from http://www.nomachine.com, with following limitations:

  • max 1 active sessions for each user
  • SSL encryption for all traffic must be turned on
