Well back to UDP, I asked a similar question on here must be over a year or two now. Someone was a great help and got me going. So I will include here a chatter2.pl which sends a UDP message. And listener2.pl that listens on UDP and writes the messages to a log and to the screen.
Since UDP sends IP address the listener also reads the local hosts file to
put out a human name instead of a number if possible.
I hope these help, note also that I'm using port 514, you will want to
change this as 514 is actually used by Unix to forward SYSLOG.
Also this was written to run on windows with cygwin installed. cygwin is
just used to time stamp and check dates so this could easy be removed
and if you turn off log writing etc. I used the date to check if I should
rotate the logs.
Well find attached two .pl files.

Please respond to OZ_Prophet
I've been working with TCP so far, and there's enough in the fine manual to
know how to do TCP... but it falls a bit short on the differences in how to
set up a UDP server. I've had a bit of a google around, but I haven't found
much there either..
I've played around a bit with two scripts on the command line (which are
probably wrong anyway, so not much point in posting them, I just want a bit
of info on how setting up an IO::Socket::INET with UDP is different) and
had
no luck. I don't know if one or both of them is broken.
if someone could show me a bit of info on how to set it up, or (even
better) a
pair of scripts that can talk from one to the other via UDP (even if it's
just a '1' every second).
However, what I want to do with this, is have a pulse-update send out over
the
Internet (a message of a few hundred bytes every 60sec, for example), and
it
would be wasteful to send the same info to each client individually... if
I'm
looking at doing something too complicated, please let me know that too 8^)
TIA
Adam
