   Wirelogd relies on the latest handshake to determine if a peer is active or inactive. While there is trafic the handshake should be renewed every 2 minutes. If there is no trafic handshake is not renewed. Based on this behavior we assume that if there is no new handshake after a while, the client is probably inactive.
