Connecting to university VPNs is always… fun. This is also true for the KIT VPN, especially because there is so much outdated information out there. E.g. there is no more Cisco compatible endpoint1) but tons of
vpnc tutorials! You have to use the Juniper Networks software
However… it worked after all. The IT guys were friendly enough to put helpful information at the online help. But to make it even easier, here are a my hints to get the KIT University Karlsruhe VPN connection running:
- Make sure you got a working Java RE. I used
sun-java6-jre, therefore I don't know if it runs with OpenJDK.
- If you are running a 64bit Ubuntu,2) you need some 32bit wrapper libraries for
sudo apt-get install libc6-i386 lib32z1 lib32nss-mdns
- Open a terminal, download and untar the
jncarchive the KIT VPN help provides for Linux:
cd ~ wget https://www.scc.kit.edu/scc/sw/juniper/7.0/linux_vpn_7.0.tar.gz
- Extract the archive and remove it afterwards:
tar -xzf linux_vpn_7.0.tar.gz rm linux_vpn_7.0.tar.gz
- There should be a
juniper_linuxdirectory within your home dir now. Change into it and run the included
cd ~/juniper_linux ./vpn-install.sh
Simply follow the instructions (e.g. you have to enter your RZ username).
- Make sure
sudo chmod a+xr /usr/local/bin/jnc
- You can remove the temporary
rm -rf ~/juniper_linux
To establish the connection, open a terminal and type
jnc -n kit. The program should start and prompt you for your account's password. Example output:
user@computer:~$ jnc -n kit Server certificate verified and CN is vpn.kit.edu. Saving in /home/user/.juniper_networks/network_connect/config/vpn.kit.edu.der. Password: Connecting to vpn.kit.edu : 443. Waiting for ncsvc for 3 seconds... done ncsvc is running, but tunnel is not established yet. Waiting for 3 seconds... done. ncsvc is running in background (PID: 2448): tunnel interface tun0, addr: 188.8.131.52
You can use
jnc stop to close the VPN connection. Example output:
user@computer:~$ jnc stop ncsvc is running, sending signal... terminated. user@computer:~$
2011-10-25: Updated the installation instructions, there is a new VPN software version (7.0).
vpncdoes not work!
