What does rtroute tell you about available destination IPs on your system? Note that every IP you want to send a message to has to be covered by some route in RTnet, i.e. either by a host or a net route. > Another hin I found says, that (when dealing with the normal kernel > ip-stack) you have to put the socket in broadcast-mode first with > setsockopt(sock,SOL_SOCKET,SO_BROADCAST,...)) but this also does not > work with RTnet (setsockopt_rt returns ENOPROTOOPT)...
