My college offers a VPN service to connect to the campus network via the AnyConnect client from Cisco.

Since I don't like to install proprietary software for a functionality that pretty much every operating system offers at this point, I was wondering if I can get around installing the AnyConnect client.

From what I found out, my college is using Cisco IPsec. For my operating system to connect it needs a shared secret or a certificate and a group name. Since the AnyConnect client doesn't ask for these details, I don't know them but the Cisco software obviously needs to figure them out by itself.

My question now is, (how) can I find out these details? Would it be possible to run the AnyConnect client and then read out the connection details?
