I just love this... You are telling me that I can't sniff information from
an SSL session using a mitm attack? the whole point is that you are in the
middle... i.e. client connects to you and you coneect to server, therefore
the SSL session with the server is between you and the server, not the
client and the server... you simply pass everything on to the client as
well, acting as the remote server... Try using ettercap, then tell me I am
wrong...
