I think you'll need more than just netcat. UDP protocols are message based, where TCP is stream based. In practical terms, this means that a UDP message (like a DNS response) has an implicit length that many of the protocols depend on... and that "message length" information would get lost when you stream the data through netcat. You probably want to write you own quick program[1] to do what netcat is doing plus a "message length" header to every datagram message. And then the equivalent on the other side. Make sense? - Rob . [1] you could probably find one that someone has already written, but this is a very easy thing to code, so, were it me, I think it would be faster to write than to find...
