How To

1. Install homebrew if you don't have it already: http://mxcl.github.com/homebrew/
2. Run brew install vpnc --hybrid
3. Check if you already have virtual tunnel interfaces, run ls /dev/tun*. If there are none, install "Tun Tap OSX" (see below)
4. Go to https://www.rz.uni-konstanz.de/angebote/e-mail/usermanager/ and login, then download both the certificate (you need the .pem file) and vpn profile
5. Run openssl x509 -in <certificateFile>.pem -noout -hash
6. Rename <certificateFile>.pem to the output of (5) with .pem as extension
7. Move the .pem certificate to a permanent location, e.g. /etc/ssl/certs/
8. Open /usr/local/etc/vpnc/default.conf in your favorite text editor, delete the contents
9. Run pcf2vpnc /.pcf and paste the output to your open text editor
