• VPN Client: Some services, as e.g. the license servers are only accessible from inside the university's network. From outside you can use a VPN tunnel to the univerity's network. See http://www.rrzn.uni-hannover.de/netz_vpn.html for details.
• SSH: You can use SSH to access your files. From inside the institute you can access afs1 with your Kerberos password. You can ask an admin to get ssh permissions for web.iqo.uni-hannover.de which is accessible from everywhere. It is however discouraged to use direct SSH via web.iqo.uni-hannover.de. You drive better by using OpenVPN and then use SSH against afs1 or any other service within the IQ network, that is SSH enabled.
