In order to use X2Go, add the following to your. The X2Go server (with some security modifications) is available as a software module on Pleiades: pfe% module avail x2go (Administrator privilege may be required for the installation.) Enable the X2Go Server on Pleiades If XQuartz is not installed on your Mac, download it from this XQuartz site and install it. You must have SSH Passthrough set up for connection from your local desktop to Pleiades. Additional information for use on Windows and Linux will be added when we learn more about using X2Go on those systems.
The information provided in this article is mostly for use on Mac systems. Mac OS X systems: you must install the XQuartz X11 server as an extra component.Linux systems: the client component of X2Go uses the local Xorg server.Windows systems: an X11 server is provided with X2Go client.The server you use depends on your local operating system, as follows: X2Go Client requires a local X11 server to display the remote sessions. Although it is not as fast as VNC, X2Go has the benefit of letting Pleiades seem like your local system without the need for an additional window manager as in the case of VNC.
Benchmarks performed by NAS staff show that X2Go provides much better performance than X11 forwarding. Choose application "Terminal".Note: X2Go is an application that enables you to do remote visualization on Pleiades. You can use this to open a single terminal from which you can launch other windows. Neither GNOME nor KDE are installed on the trcomp nodes. Over low bandwidth connections, XFCE is the preferred desktop-manager because it is simple and lightweight. In the Media tab of session preferences, disable sound-support. ssh-key authentication can be used making single-click passwordless connections possible.ĭownload and install the X2Go client for your platform Configuring X2Go for connecting to a trcomp nodeĬreate a session for the trcomp node that you want to use. Connections use the built-in ssh client of the X2Go client. It can be used for a single-application or a full remote-desktop connection. It is available on the trcomp nodes via X2Go.
A superior approach is the NX protocol developed by. However, this does not work particularly well on low-bandwidth or high latency connections because X11 creates many round-trips which adds significantly to the rendering delay. Graphical applications can be run by tunnelling X11 over an ssh connection.
