Neither worked for me, though like I > said getting the MAC address from the request packet works fine. I was trying to say that if you want to generate a packet out of the blue and send it somewhere, a good way of having the info there ahead of time would be to run a config on the remote machine, which would send a ping to the Siteplayer server. The server would examine the contents of the ping, and if it contained a command that the server recognized, it would cache that IP and MAC, then it would use them next time that it wanted to send a packet out of the blue. I agree that this is not the best way to handle it, but I think it would work. Cheers, --Brendan -- http://www.piclist.com hint: The PICList is archived three different ways.
