You know more than I do, although our minds do get filled with details and I sure need refreshers of details often. I have been successful in writing a few simple samples of sending and/or receiving UDP. In particular, see my: UDP Send and Receive Using CAsyncSocket http://simplesamples.info/MFC/UDPSendReceive.php I tried it to see what happens relevant to this discussion, and got some interesting results. When I remove ZoneAlarm's configuration of the program, so that it does not know anything about the UDPSendReceive program, then when I execute the program, ZoneAlarm asks if it can access the internet. If I answer by saying to deny access, then the send does not work. However every subsequent send (without closing the socket) works. If when I tell ZoneAlarm to deny access, I also specify to save that answer, then when I execute the program ZoneAlarm does not ask anything, as it should (not), but the first send does not work. Every subsequent send does work. So I am a little confused, but this is not a php topic. I am curious about the details and I will check into it when I have time, but I will go to a networking group or forum to pursue this further. I have used ethereal but it has been a while. I have not read that article but that is where I am likely to start when I pursue the issues I describe above. > You may also want to check that everything is set up > correctly in your 'hosts' file (C:\Windows\hosts ?) so that the > system itself knows as much as it can. I have the following in my hosts file: 127.0.0.1 localhost I assume that is correct. -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
