in reply to Simple UDP example anyone?

Recipe 17.5 of the Perl Cookbook is handy:

use IO::Socket;
use strict;

my $sock = IO::Socket::INET->new(
    Proto    => 'udp',
    PeerPort => 5000,
    PeerAddr => 'hostname',
) or die "Could not create socket: $!\n";

$sock->send('a file to have your advice') or die "Send error: $!\n";

perlipc has other examples. IO::Socket is slightly easier than Socket, and translating between the two isn't terribly difficult.

[mitd]

$sock->send('a file to have your advice')

Now thats what I call a datagram with a message.

lol, chromatic++

What few people mention is that IO::Socket doesn't work under Solaris (I believe that Sun has hardcoded the constants to non-standard values or similar rubbish) and you get stuck with using Socket

IO::Socket actually does work under Solaris. I've been using it for XML servers on 4 different Solaris boxes ranging from 5.6 to 5.8. It's actually really sweet.

I actually have done the same, and have successfully coded many a daemon to run on solaris systems. Sun can be very nice to you when you learn to use it.
