Sending UDP from webaccount

[ares23]

Hey there,

We have a Bluehost web account which we're building a service on that requires UDP packets to be sent.

I put together the following test script to see if such a thing was possible:


#!/usr/bin/perl

print "Content-type: text/plain\n\n";

use IO::Socket;
$handle = IO::Socket::INET->new(Proto => 'udp') or die "socket: $@";

$PORTNO = 4767;
$HOSTNAME = "89.10.14.81";

$ipaddr = inet_aton($HOSTNAME);
$portaddr = sockaddr_in($PORTNO, $ipaddr);
$res = send($handle, "123thisisjustatest", 0, $portaddr) or print "cannot send: $!\n";
print "sent $res\n";

The script seems to run ok, but the send() operation fails with "Operation not permitted". I presume this is a security precaution (although the packet is sent on a port higher than 1024).

Does anyone know why this wouldn't work on Bluehost? Is this something we have to ask for permission to do, etc?

Thanks,

Ares.

BlueHost have all the ports that a website doesn't normally need closed by default. Presumably this would include all the UDP ports since a web site doesn't normally use those.

If you have a dedicated IP address then one of the extra options that gives is the ability to open additional ports. I am not sure if that includes the UDP ones or not though. You'd probably do best to ask BlueHost support.

Ok, thanks for the help felgall.
