Answer 5

OpenVPN , :

service openvpn stop

( perl)

/etc/init.d/openvpn stop

You can kill it directly, like another sentence, but using the provided method to stop the service, any cleaning of additives that OpenVPN requires (for example, cleaning lock files, launching pid files, etc.) will be performed.

Killing AFIAK OpenVPN will be fine in the current version, but who knows for a future version.
