openconnect shuts down gracefully when it receives SIGINT or SIGTERM.
This is documented in the openconnect.8 man page.
SIGNALS
In the data phase of the connection, the following signals are handled:
SIGINT / SIGTERM
performs a clean shutdown by logging the session off, discon‐
necting from the gateway, and running the vpnc-script to restore
the network configuration.
SIGHUP disconnects from the gateway and runs the vpnc-script, but does
not log the session off; this allows for reconnection later us‐
ing --cookie.
SIGUSR1
writes progress message with detailed connection information and
statistics.
SIGUSR2
forces an immediate disconnection and reconnection; this can be
used to quickly recover from LAN IP address changes.
