Remote connection

A Software


1. VPN-Client

Access to the university network is via Cisco AnyConnect Secure Mobility Client. Download the client from the ZID-Homepage and install it.


2. SSH-Client

To establish a connection to the server, download Putty or a similar SSH client. Starting with Windows 10, you can also use the Windows Power Shell.


3. VNC-Client

With a VNC Client such as Real-VNC you can transfer the entire desktop of another computer. Alternatively, you can use an X server.


B Connection

Whenever you want to remotely connect, you must always first establish a VPN connection to the university network. To do this, start Cisco Any Connnect Client and enter the address of the VPN server of the University of Leoben: in the Connect to field. Then log in with your m- or p-account.


1. Terminal connection

Start the SSH client. For the connection, you must specify three parameters (either in the settings, or as you establish the connection for the first time):

  • The user account we assigned to you (probably your family name)
  • The name of the computer you want to connect to (e.g.
  • The port number for the connection (22 is an acceptable default value).

Upon login you need your regular user account password.

2. Prepare remote desktop VNC connection

In order to connect via VNC, you must first start a VNC-server on the computer that you want to connect to. This is why you must first establish a terminal connection as described above. In this terminal type

> vncserver -list

to see whether you have already a VNC server running. The list may look like this

TigerVNC server sessions:

:3                     31065

This shows that there is a VNC-server running at port (X-display) number 3. If it is, for some reason, malfunctioning, type

> vncserver -kill :3

If no VNC-server is running, you must start one with the command

> vncserver -geometry 1800x1024 -depth 24 :XX

and XX is the port/X-display number. You are free to choose this number, but no two users can use the same port, and it shouldn't be the port you use for the terminal connection (1). Please use a two-digit number and stick with it!

When you started a VNC-server for the first time, you must also create a VNC-password with the command

> vncpasswd

3. Active remote desktop VNC connection

Start your VNC-client. The connection parameters are similar to the terminal connection, but with the port number you chose for the VNC-server. In most programs you can enter them in the form USERNAME@COMPUTERNAME:PORTNUMBER. Your credentials are not your regular login, but the VNC-password.

To exit VNC, do not log out but just close the VNC-window. In case you did log out, you have to restart the VNC-server as discussed above.
