Setup LRZ VPN without Cisco on Ubuntu

I don't like the Cisco Anyconnect client, so I searched for a way to get the LRZ VPN to work without the need to install the software. Here it is:

1. Go here, login with LRZ credentials at the bottom
2. Search for the lrz.pcf, download it
3. Open the file, find the line with enc_GroupPwd=[the hash], and copy the hash after the equals sign
4. Install: sudo apt install vpnc network-manager-vpnc network-manager-vpnc-gnome
5. Run cisco-decrypt [the hash] (the command is part of vpnc) in the terminal and copy the resulting unencrypted password (found this here, thanks)
6. Go to the network settings, add a VPN, select vpnc, and enter the following settings:

• Gateway: ipsec.lrz.de
• User name: (your LRZ username)
• User password: (enter if you want)
• Group name: mwn
• Group password: (the text decrypted above)

7. Done!
