UDP broadcast

 [1/4] from: rebol-list2::seznam::cz at: 18-Jun-2003 16:54


Hello rebol-list, I've found this UDP broadcast example (by Norman Deppenbroek): data: "1101001011110000" ; port 54000 binary notation as text to bc forever [ connection: open udp://255.255.255.255:54000 set-modes connection [ broadcast: true ] insert connection data print [ now/date "*" now/time ] close connection wait 0:15:0 ; wait 15 minutes for next broadcast ] but when I listen on udp://:54000 I'm not receiving any messages. Does anybody know how to set-up the UDP broadcast listener? Thanks, Oldes

Hi Oldes, There is a sample udp server and client example in the docs. http://www.rebol.com/docs/core23/rebolcore-13.html#sect15. Not sure if it is uptodate though. Cheers, Allen K

This worked for me: Session 1:
>> server: open udp://:54000 >> forever [wait server print [now copy server]]
Session 2 (As below, but I reduced your wait time to 30 sec. for testing) Bohdan "Bo" Lechnowsky Lechnowsky Technical Consulting At 04:54 PM 6/18/03 +0200, you wrote:

Hello RebOldes, There are more way to do it but below an example how to listen: listen: open udp://:54000 forever [ print copy wait listen udp://:54000 ] By the way, i was yesterday sniffing the internet and i found some nice examples of Multicasting on the French Rebol site...
