In addition to using the web browser based access to ECMWF via NX described previously, you can also download a standalone NX client. To do this, go to www.nomachine.com/download and select the NX client for your platform. The installation is quite straightforward and is described in more detail at www.nomachine.com/documents/client/installall-document. You can then use the "Download session file" option available through the web interface:
...
This URL allows you to download a complete configuration file which can be used with your standalone NX client. You can have multiple configuration files, say one for a standalone xterm on ecgate and another one for a full virtual desktop still on ecgate, and then select the appropriate one from your NX client.
Alternatively, you can use the NX client "Wizard" to setup your own configuration as described in the NX client documentation available at www.nomachine.com/documents/configuration/client-guide.php We recommend using this option for advanced users only. We also recommend that you first look at one of the configuration files which you can obtain by downloading the "session file". The first time you start the NX client the following window will appear:
You will have to click "Next" where you will be asked to enter the name of your NX session (in the example <your session>) and the host to connect to. You will have to enter the ECaccess host name "ecaccess.ecmwf.int" as host:
You will then get the following window where you can choose you type of desktop. You will need to choose "Unix" and "Custom":
Click on "Next" to get the following window:
Check the "Show the Advanced Configuration dialog" box and click the Finish button. You will get the following window:
If you then click "Ok" you will be able to start your session. In this case you will get a standalone xterm on ecgate. Depending on your firewall setup you may get various warning messages. You will need to authorise all sessions from anything related to NX (nxclient, nxauth, nxssh, etc).

WindowMaker is a popular window manager for the X Window System, allowing graphical applications to be run on Unix-like operating-systems. It is designed to emulate NeXT's GUI as an OpenStep-compatible environment and has been described as "one of the most useful and universal window managers available." WindowMaker has a reputation for being fast, efficient and highly stable and is very popular among open source solutions for use on both newer and older machines. More information on WindowMaker can be found at http://en.wikipedia.org/wiki/Window_Maker and www.windowmaker.info. WindowMaker is the window manager which is used when you connect with NX to either ecgate or the supercomputer and select the "virtual desktop" option. For example, when you connect to ecgate using the virtual desktop you will get a desktop as shown in figure 2. here:
The main customisation which has been implemented is a specific "Application Menu" which you can obtain when right-click (opposite mouse button for left-handed mouse) on the desktop. The menus on ecgate and the supercomputer are designed to be very similar with the one on ecgate offering more choices regarding the available applications. The usage of the menus should be quite straightforward. To terminate a WindowMaker session you need to select the "Exit" option from the menu
