Remote Visualisation via a Web Interface

It is possible to access both the Linux Cluster and the SuperMUC via an easy-to-use web interface.

Login page:


You will need an account for the system you intend to use, which you can request here for SuperMuc and here for Linux Cluster. Additionally your web browser should support web sockets:

Logging In

When you have entered the web page at you can choose the system to login on the top of the page which is either

  • SuperMUC VNC Client - for remote visualisation on SuperMUC
  • Linux Cluster VNC Client - for remote visualisation on the Linux Cluster

You can set the duration of your session in the field “VNC Session Reserved Time (hours)”. After this period has passed you are automatically logged out from the VNC session. The default value is 2 hours and the maximum duration is 48 hours.

Initially you have to set your VNC password which you will use later by clicking in the checkbox and entering it in the field below. In general you only have to set it once. But you have the option to reset it if required.

You can now log in to the system with different authentication methods

  • Username/Password

Simply enter your username and password, for the given system you have chosen to login - either SuperMUC or Linux Cluster

  • MyProxy Certificate

You can use your username on the system you intend to log in (in case you have multiple accounts) and have to enter the MyProxy username/password combination you have used when you uploaded the initial certificate to the LRZ MyProxy server. This can be triggered by clicking on the top bar under “MyProxy Client” a detailed documentation can be found here.

  • SLCS Proxy

You can use your username on the system you intend to log in (in case you have multiple accounts) and have to provide a SLCS username and upload the certificate for authentication. A detailed documentation how to receive an SLCS certificate can be found here.

Finally you click on the “Login”- button

Connect your web based VNC client to the remote desktop

When you have clicked on the “Login”- button a dialog will appear showing the URL to your VNC session. An additional tab or browser window will open, providing the login to the VNC session which can be also accessed via the link you received from the previous dialog.

You’ll be asked to enter the VNC password you have set during login, or set in a previous session. Once you enter this password and click on the “connect” button, you will see your remote desktop in the browser window. You might have to scroll down to find the x-term Button in order open a terminal window.

Once you have opend a terminal on the remote system you can launch your applications as described here.

A very brief quick start guide illustrating this process graphically is found here.

When you have finished working with the remote visualisation please disconnect by pressing the button in the top right corner of your window. Also choose Logout and Terminate VNC Sesson in your Login tab or window.
