The Following code works fine on my Win32 based system (with the server
part running on the Linux system)...
##------------------------------------------------------------------------------
#!/usr/local/bin/perl -w
use strict;
use vars qw/$sock $msg/;
use IO::Socket;
my $app_mode = $ARGV[0] || '-c';
if (lc($app_mode) eq '-c') {
print "Entering Client mode...\n\n";
$sock = new IO::Socket::INET(
LocalHost => '0.0.0.0', # Manually set the client's origion
addr/port
LocalPort => '3051',
PeerAddr => '192.168.0.255',
PeerPort => '3050', # Port the udp server listens on
Proto => 'udp',
Broadcast => 1 # Not sure if this is needed, I know the sockopt is
) || die "[ERROR] $!\n";
$sock->sockopt(SO_BROADCAST, 1);
print $sock "test\n";
}
# [snipped rest]
# ('else' it acts as a server lisening on UDP port 3050.)
##------------------------------------------------------------------------------
But on my linux system (RH 7.3) I get "permission denied" from $! when I
try to create the socket. (Running the server part on the Win32 box,
though the lcient on the linux never gets passed the "new
IO::Socket::INET" statement.
$ ./udptest.pl -c
Entering Client mode...
[ERROR] Permission denied
And I tried logging in as root (su - root and even hitting alt+ctrl+F1
and lgging in as root from there.) Either way I get the same result.
Is there a simple way around this, without enabling something in the
kernel or so, as I want this program to send to an entire network and be
portable.
Thanks for any help.
