Your method really does work, so I'm closer. I just don't know how to find the sender IP. Thanks a lot BTW.

But, what I was actually asking is about how to find the sender IP. Check out the recv() I posted above.

UDP doesn't really connect, so the source IP on each packet can be different. recv() returns some packet header info from which I can get the ip addr of the sender.

Sysread doesn't do that at all. And the worse part is, the perldoc page for select() tells me that mixing your vec/select call with recv() is stupid and I'll get burnt.

So I'm not sure what to do ...
