Hi, > How i can avoid this and make the data go through the real hardware? You can try manipulating the kernel IP routing table. You can do it by the route command (see man route for more info). > How and when it understands the address is local and associates the loopback > device for trasmission? It understands during IP layer processing. IP layer has two queues INPUT & OUTPUT packet queues. Whenever it understands the destination address is for the same machine by seeing the routing table, it just puts the packet from OUPTUT queue to INPUT queue. To see whether pakcets are coming onto cable, use tcpdump(). You can make out clearly whats happening on the network. --vijayck -- Kernelnewbies: Help each other learn about the Linux kernel.
