I want to get a test server going. The client will recv an xml file from one socket. When the that is read in it then sends an xml to a receiving socket. These two sockets have different ports but should be the same address. So far the sending works but the revcing seems to not get anything. Any ideas?

#!/usr/bin/perl -w
 
use strict;
use IO::Socket;
use File::Slurp;
use threads;

my $socket=new IO::Socket::INET->new(PeerPort=>12345,Proto=>'udp',Peer
+Addr=>'localhost');
print "This is a test Sending Server\n";

my $capxml = read_file("C:\\Users\\deadpickle\\Desktop\\UAS\\GRRUVI_1.
+60\\test xml\\capabilities.xml");

my $recv = threads->new(\&recvxml);
my $send = threads->new(\&sendxml);

while(1){
}

sub sendxml{
    my $socket=new IO::Socket::INET->new(PeerPort=>12345,Proto=>'udp',
+PeerAddr=>'localhost');
    while (1) {
        #send capabilities every 10 seconds
        $socket->send($capxml);
        print "Sending Capabilities\n";
        sleep 10;
    }
}

sub recvxml{
    my $xml;
    my $socket=new IO::Socket::INET->new(PeerPort=>56789,Proto=>'udp',
+PeerAddr=>'localhost');
    while(1) {
        print "Waiting for meassage\n";
        $socket->recv($xml,3000);
        print "Recieved Message: $xml\n";
    }
}

with the section of the client that sends the xml file(the real program is 2000+ lines, not forum friendly):

sub sendxml {
    $SIG{PIPE} = "IGNORE";
    $\="\n";
