A program that is a straight adaptation from the IO::Socket::Multicast
man page does not work either:
----
#!/usr/local/bin/perl
use strict;
use IO::Socket::Multicast;
use constant GROUP => '233.7.117.79';
use constant PORT => '4011';
my $sock = IO::Socket::Multicast->new(Proto=>'udp',LocalPort=>PORT);
$sock->mcast_add(GROUP) || die "Couldn't set group: $!\n";
while (1) {
my $data;
next unless $sock->recv($data,1024);
print $data;
}
----
It only displays data if the multicast stream already exists on the
local Ethernet, but it does not send the group join request out to
initiate the receiving stream on the local Ethernet.
