Hi : I was using libpcap to do some node discovery work, initially, I send a broadcast to all nodes on the network, each node will reply to this broad cast with it's unique ID. I opened pcap in live capture mode. Since in live capture mode, i can only read 1 packet per capture. i wonder if all the nodes try to send reply at the same time to my host machine(the one captures the packet), how do i make sure i will read all reply packet ? I am using pacap_dispatch() function. Are packets stays in the buffer, while the dispatch call my handler and pass the packet one by one ? or other packets simply dropped ? Thank you! chris
