Hi Monks,

Congratulations for your nice Web which I've used as reference several times. This is my first post.

I started to study perl around 3 months ago playing with basic stuff. While studying sockets in Perl, and as part of my "training" I played with dup2 system call to redirect file descritors like this (I used another piece of software as reference):

while (1) {
my $client = $server->accept();
fcntl $client, F_SETFD, 0 or warn "$!";
die "can't fork: $!" unless defined( my $sspid = fork() );
if ( !$sspid ) {
   close($server);
   while ( defined( my $line = <$client> ) ) {
      if ( $line =~ /_exec_/i ) {
         POSIX::close(0);
         if ( defined( my $fd = fileno $client ) ) {
            POSIX::dup2( $fd, 0 );
            POSIX::close($fd);
            POSIX::dup2( 0, 1 );
            POSIX::dup2( 0, 2 );    
            eval {
               exec "/bin/bash" or warn "$!"; 
            }; warn "TRAP : $@\n" if $@;
         }
      } else {
         print $client $line;
      }
   }
   close($client);
   exit 1;
}
}

Now I would like to do exactly the same but using SSL (Net::SSLeay, I've used CPAN SSLeay documentation as reference)

How can I redirect STDIN, STDOUT and STDERR to a socket using SSL? The idea is to execute commands remotely, just as in the previous example.

Thanks in advance and kind regards,
Ernesto
