Hello everybody! I'm developing a network application which needs *to intercept* a packet (not just *copy* a packet, like libpcap does), move this packet into my application (userland), do some checking in the packet and according with some heuristics, the application may change the payload and re-inject the modified packet into the network. Note that sometimes, I'll change the payload, drop the packet or just let it go. So, how can a I do that in FreeBSD? I can use 6.1, 7.1, any version. Thanks in advance, --fx _______________________________________________________ Yahoo! Mail - Sempre a melhor opção para você!
