Hi
I'm busy trying to simulate spanning tree protocol on a collection of
BSD machines (2.2.8).

I have configured the bpf0 interface and can noe read from it with no
problems.

What I need to do now is write my pre formated ethernet frame.  I have
tried in perl to open the device and write to it via a filehandle.  I
have also tried to write to it on the command line.

Can anyone please tell me how to post a packet onto my LAN via this
interface.

Thanks in advance,

Tom Brown
