Hi, I'm new to perl (allthough Im pretty good with php and delphi) and have been making some small programs. I just started a program and allready am stuck. I am trying to make a server/client app. All that th server does is accept connections, and on reading data from a client, sends it to every other one. The client should connect to the server, receive data from it, and send data to it, a very very simple chat application in short. I am having problems with the server, to manage the different connections, I am using the select() function, as described here: http://www.perlfect.com/articles/select.shtml My code allmost exactly the same as that, and it still deosnt work, for a start I would like it to print the data received from the clien on the screen, what is wrong here (it never prints the data to the screen)?: 
#!/usr/bin/perl
#test script

use IO::Socket;
use IO::Select;

if(@ARGV < 1)
{
        printf("Usage:\ntest.pl <port to run on>\n");
        exit();
}

my $sock = IO::Socket::INET->new(
                                Proto=>"tcp",
                                LocalHost=>"Localhost",
                                Listen=>16,
                                Reuse=>1,
                                LocalPort=>$ARGV[0]
                                ) or die("Could not create socket!\n")
+;


my $readSet = new IO::Select();
$readSet->add($sock);

while(1)
{
        my $rhSet = IO::Select->select($readSet, undef, undef, 0);
        foreach $rh(@rhSet)
        {
                if($rh == $sock)
                {
                        $newSocket=$rh->accept();
                        $readSet->add($newSocket);
                } else
                {
                        $buf=<$rh>;
                        if($buf)
                        {
                                printf "$buf";
                        } else
                        {
                                $readSet->remove($rh);
                                close($rh);
                        }
                }
        }
}

I have allready anticipated another problem I will have. As you see, it accepts any new sockets, but what if, I want to send data to all open sockets the server has received? I see no where (array, etc) where the sockets are saved. Any help?
