How to shut down openconnect cleanly? I tried using openconnect today for the first time to connect to my organization's VPN. However, once connected, it runs in the foreground of the terminal and the only way I could see to close the connection was to use `CTRL-C`. Is this an acceptable way to close the openconnect session cleanly? If not, what is the preferred method?

Yes, `Ctrl-C` (i.e. SIGINT) cleanly shuts it down, according to <

Personally I run openconnect in a terminal and use `Ctrl-C` to shut it down; some people might prefer to use NetworkManager, systemd-networkd, etc. to manage openconnect connections.
