SSH dynamic (SOCKS) proxy

If you do not need a full VPN but only access to internal Web services like renewal of a student account or creation of renewal of a VPN profile/certificate, you can use a dynamic proxy via SSH:

First step: create the tunnel

  • Unix, MacOS-X: ssh -D7777 login.cs.uni-bonn.de (students) or ssh -D7777 hera.cs.uni-bonn.de (employees)
  • Putty running on Windows:
    1. In Session: Host login.cs.uni-bonn.de (students) or hera.cs.uni-bonn.de (employees)
    2. In Connection: open the sub-menu SSH
    3. In Tunnels: destination dynamic, source port 7777, ADD
    4. Then Open

Second step: use the tunnel

Finally, configure in your web browser localhost:7777 as the Socks V5 proxy.

This example is for firefox 60.esr, English version:
