That shouldn't be a problem, except for the communication API and the capture-packets-with-timestamp API are separate. Remember that there's no guarantee that send() recv() calls correspond in any way to the actual packets sent/recevied. > The sockets library is of course great for the communication, > and I've seen some python libraries that do packet sniffing > and record timestamps, but it's not clear that I can do both > at the same time. Yes, you can do both at the same time. But you have to use separate APIs. -- Grant Edwards grante Yow! TONY RANDALL!
