Hi,
I'm trying to work with perl sockets, in win-32, with one server listening to multiple clients.

I was able to make the server listen to multiple clients and send data from each client to the server, but I'm unable to reply to each of the client from the server.

My query is like this:
client socket1 ----> "hello server" ----> server
client socket2 ----> "hello server" ----> server
client socket3 ----> "hello server" ----> server

server ----> "hello client1" ----> client socket1
server ----> "hello client2" ----> client socket2
server ----> "hello client3" ----> client socket3

My Client:

...
...
use IO::Socket;
    
    $remote_host="some_host_name";
    $remote_port=1234;
    
    #$soc=IO::Socket::INET->new("$remote_host:$remote_port") or die $@
+;
    $socket = IO::Socket::INET->new(PeerAddr => $remote_host,
                                    PeerPort => $remote_port,
                                    Proto    => "tcp",
                                    Type     => SOCK_STREAM)
    or die "Couldn't connect to $remote_host:$remote_port : $@\n";

    
    #....do something with the socket
    print $socket "New host\n";
    
    $answer=<$soc>;
    
    print $answer;
    
    # Terminate the connection
    #close(TO_SERVER);
    close($socket);
}

My Server:

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

{

    # Create a socket to listen on.
    my $listener=IO::Socket::INET->new( LocalPort => 5498, Listen => 2
+, Reuse => 2 );
        die "Can't create socket for listening: $!" unless $listener;
        print "Listening for connections on port 5498\n";
    
        my $readable=IO::Select->new;     # Create a new IO::Select ob
+ject
        $readable->add($listener);          # Add the listener to it

        while(1) 
        {
            # Get a list of sockets that are ready to talk to us.
            my ($ready) = IO::Select->select($readable, undef, undef, 
+undef);
            foreach my $s (@$ready) 
            {   
                # Is it a new connection?
            if($s == $listener) 
            {
                    # Accept the connection and add it to our readable
+ list.    
                    my $new_sock = $listener->accept;    
                    $readable->add($new_sock) if $new_sock;       
                    print $new_sock "Welcome!\r\n";                
                    open FILE, ">out.exe" or die "Can't open: $!";    
+                      
                    while ($new_sock = $listener->accept()) 
                    {
                    while (defined ($buf = <$new_sock>)) 
                    {
                     print FILE "$buf";                         
                    }
                    close FILE;
                }    
                } 
                else 
                {  
                    # It's an established connection 
                    
                    print "established s $s listener $listener\n";
                    print $listener "Why don't you call me anymore?\n"
+;
                    
                    my $buf = <$s>;   # Try to read a line

+If not,
                                # echo what they said to us.

                                {
                                    print $s "See you later!\n";
                                    $readable->remove($s);
                                    $s->close;
                                } 
                                else
