hi guys hi master of "Fu" any update I am doing some research on the server and client for the chat. I have long taken the trouble to consult the documentation that is different and both PerlMonks different pages that deal with this vast subject. I try to find a minimal example because I want to turn into non securise securise. here is the status of my research
#!/usr/bin/perl
use warnings;
use strict;
use IO::Socket::SSL 'inet4';
use threads; use threads::shared; $|++;
print "$$ Server started\n";
# do a "top -p -H $$" to monitor server ++ threads
our @clients : shared; @clients = ();
my $server = new IO::Socket::SSL( Timeout => 7200, Proto => "tcp",
LocalPort => 42000, Reuse => 1, Listen => 3, SSL_use_cert => 1,
SSL_verify_mode => 0x00, SSL_key_file =>
'/home/swilting/perltest/private/localhost.key' +, SSL_cert_file =>
'/home/swilting/perltest/certs/localhost.cert', SSL_passwd_cb => sub
{ return "" },
);
my $num_of_client = -1;
while (1) { my $client;
do { $client = $server->accept; } until ( defined($client) );
my $peerhost = $client->peerhost();
print "accepted a client $client, $peerhost, id = ", ++$num_of_client,
"\n";
my $fileno = fileno $client;
push (@clients, $fileno);
#spawn a thread here for each client
my $thr = threads->new( \&processit, $client, $fileno, $peerhost )
+->detach(); }
# end of main thread
sub processit {
my ($lclient,$lfileno,$lpeer) = @_;
#local client
if($lclient->connected){
# Here you can do your stuff # I use have the server talk to the client
# via print $client and while(<$lclient>)
print $lclient "$lpeer->Welcome to server\n";
while(<$lclient>){
# print $lclient "$lpeer->$_\n";
print "clients-> @clients\n";
foreach my $fn (@clients) {
open my $fh, ">&=$fn" or warn $! and die;
print $fh "$lpeer->$_" } } }
#close filehandle before detached thread dies out
close( $lclient);
#remove multi-echo-clients from echo list
@clients = grep {$_ !~ $lfileno} @clients; }
__END__

$mw ->bind('<Any-Enter>' => sub { $txt->Tk::focus });

#Server.pl
#!/usr/local/bin/perl
use strict; use warnings; use IO::Socket::SSL 'inet4';
my $server = IO::Socket::SSL->new( LocalPort=> 42000,
## Type=>SOCK_STREAM,
Reuse=>1, Listen=>5, Proto => 'tcp', SSL_use_cert => 1,
SSL_verify_mode => 0x00, SSL_key_file =>

while(my $line = <$client>){
print "CLIENT says:$line\n"; } }
else{ while(my $line = <>){
print $client "$line\n"; } } }
redo; close($server); <>;
the server running the threads fails with a segmentation fault and my
client fails after two requests I do not know why and characters
displayed on the client encodes are poorly I do not know either why
