Fake IKE PSK+XAUTH daemon based on VPNC

This is a fake IKE daemon supporting just enough of the standards and Cisco extensions to attack commonly found insecure Cisco PSK+XAUTH VPN setups. If you know the pre-shared key, also known as shared secret or group password, you can impersonate the VPN gateway in IKE phase 1, and learn XAUTH user credentials in phase 2.
