Corion has written a module that uses Pcap/WinPcap (which is something similar, or even related, to Ethereal) via Net::Pcap to sniff TCP connections, more specifically, HTTP connections: Sniffer::HTTP. I know, I know, you asked about UDP packets... But perhaps you can use it as a basis/inspiration for a tool for your purpose.	[reply]

the usual way for any (serious) networking server application is to log requests and responses into a file. this way you'll actually see what got there and what was sent..as UDP is not guaranteed delivery..so a trace is not an accurate measure of the conversation. the hardest line to type correctly is: stty erase ^H	[reply]
