udp broadcast example, please

[Torsten Rueger]

Moi,

sorry, but I've searched and searched to find exact information on how
to do a simple udp broadcast client/server, but can find it:

I want to have a thread pinging (very small message) and possibly the
same thread receiving maybe with a 1 second timeout. And the same code
should be able to run as multiple instances on the same machine.

Could someone with experience please post the 10 lines to make this
happen. Please no general comments or things that "should" work. I've
tried for hours with various socket options and addresses, so I would
very much appreciate working code.

Thanks
Torsten

Have you searched on your hard drive?
It's right there: Demo/sockets/udpecho.py
in the python source tree.

There's an example how to send and receive UDP packets.
