Hi,

select kinda does the trick. I can now monitor the server. If the client disconnects, it is captured and the thread running the read/write is killed.

now I have another problem. Even though a new socket seems to be opened after reconnect, I can only write to it, when I have the print"$pid \n"; before cancelling the thread. If i comment that out, it just prints out:

SEND( TYPE q or Q to Quit):

RECIEVED:

SEND( TYPE q or Q to Quit):

RECIEVED:
SEND( TYPE q or Q to Quit):Use of uninitialized value $send_data in sc
+alar chop
at select_server.pl line 46, <STDIN> line 5.

RECIEVED:
SEND( TYPE q or Q to Quit):Terminating on signal SIGINT(2)

The error above shows up when hitting CTRL-C

What am I missing?

use IO::Select;
use IO::Socket();
use threads;
use threads::shared;
use Thread::Cancel ;
use strict;
use warnings;
my $Thread;
my $lsn = new IO::Socket::INET(Listen => 1, LocalPort => 5000);
my $sel = new IO::Select( $lsn );
my $tid : shared;
    while(my @ready = $sel->can_read) {
        foreach my $fh (@ready) {
           if($fh == $lsn) {
                # Create a new socket
                my $new = $lsn->accept;
                $sel->add($new);
                my $Thread = threads->create( "echoserver", $new);  #s
+tart the echo-server as a seperate thread
                #$Thread->detach();
                 }
            else {
                # Process socket
                # Maybe we have finished with the socket
                print "$tid\n";
                my $Thread = threads->object($tid);  #get handle of cu

                $sel->remove($fh);
