LINUX network 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.


3. X-server

If you want to display individual LINUX/UNIX windows on a Windows desktop, you need an X-server such as Xming. Alternatively, you can use a VNC client.


4. 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


For each connection to the university network, a VPN connection must always be established first. 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 and specify your user name (e.g. geophysik), the name of the server (e.g. and the port (22) for the connection. For some programs you may enter everything together, e.g.

2. Terminal and X-windows connection

Start the X-server and open a terminal with the SSH client (see 1.) Make sure that X window forwarding is supported for the SSH connection. In the configuration (for PuTTy e.g. under Category > Connection > SHH > X11) "X11 forwarding" or "X tunneling" must be activated.
X windows that are called from the SSH terminal (e.g. via okular, suxwigb or similar) now appear on your desktop. With multiple and especially interactive windows, this connection may be quite slow.


3. Remote desktop connection

If the connection is already set up, then you just need to start your VNC client and log in with the password you assigned. You will then get the entire remote desktop as a separate window on your screen.

To set up the remote desktop connection, first establish a terminal connection with an SSH client (see 1.). In the terminal you then configure the VNC server with the command

> vncserver -geometry 1800x1024 -depth 24 :XX

Where XX is the display number you have been personally assigned.

Then create a password with the command

> vncpasswd

To see if your server is still running use the command

> vncserver -list
