Hi,

I am trying to pass a hash reference from server to client. I then try to print the content of the hash. However, there appears some error in my programs and the client does not print the output and simply hangs on its terminal.

Please let me know what is a good way to do this.

Thank you.

#tcpserver.pl

#!/usr/bin/perl
use strict;
use warnings;
use IO::Socket::INET;
use Storable qw(nfreeze);

$| = 1;

my ($socket,$clientsocket);
my ($peeraddress,$peerport);
my $data;
my $line;

my $inputfile = "list.txt";
my %names=();
my $reftohash;

open(RF, "$inputfile");    # read file

while ($line=<RF>) {
    chomp $line;
    $names{$line}=1;
}

#set hash reference
$reftohash=\%names;

$socket = new IO::Socket::INET (
    LocalHost => 'localhost',
    LocalPort => '5000',
    Proto => 'tcp',
    Listen => 5,
    Reuse => 1
) or die "ERROR in Socket Creation : $!\n";

while(1) {
    $clientsocket = $socket->accept();
    print $clientsocket nfreeze($reftohash);
}

$socket->close();
