ie ensure openvpn has "--management" configured, then you can query that and it will tell you the name of the client cert, what local IP was allocated and what their external IP is. Then a packet sniffer (eg tcpdump) can be used to see what traffic is being generated - either internal or external (obviously the external will all be encrypted openvpn traffic - so it's not very interesting) -- Cheers Jason Haar Corporate Information Security Manager, Trimble Navigation Ltd.
