Hi In the previous message, I have asked "it is said to use SO_BINDTODEVICE, you still need to have a route pointing to the device. SO_BINDTODEVICE only allow you to choose device among the different routing priorities.". So if I send a packet to 127.0.0.1, will it be routed to lo, even if I have previously binded the socket to eth0?

You answered our own question: you've asked Linux to send all the packets fromthat sockets through eth0. the loopback device is a different interface (lo), so why do you expect to be able to talk another application that is listening to the loopback interface? > Does this mean LINUX do not use a standard implementation? No, it means you need to figure out what you want :-) Gilad -- Gilad Ben-Yossef <gilad@codefidence.com> Codefidence.
