I am trying to use ifconfig to turn on broadcast on my loopback interface. It currently reads:

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384

As you can see, no broadcast address! :( :( :(

I tried this on OS/X but it did not work and it did not give any error or feedback:

ifconfig lo0 broadcast 127.255.255.255

Any guru would know that?


I have one server that sends one packet. I have two clients running on the same machine as the server. I need them to pick up the packet WITHOUT having to force the server to send it twice.
