Hi there,
I was wondering what were the libraries out there available to make my own
kind of 'tcpdump' in C++? Or maybe it would be more easy to ask the firewall or
tcpdump to send the interesting packets to my program through a socket or something?

Thanks for your input!
Simon

Use tcpdump with output to a FIFO, selecting packets using the packet
display filter expressions? Read from FIFO with your program?
