Hello Monks

I have been looking at this for too long, hopefully someone can spot what is going on!

I have an inhouse system where I need to have users click a link and start a reverse SSH tunnel. The script itself is simple and works. Running it from shell and it connects with no STDOUT. However, when I try to fork it from a web page the page hangs (like it would if I wasn't forking) and stays there forever. The process starts fine, but the page doesn't redirect.

.....
my $port = $cgi->param("port");

if ( $port ) {
    my $cmd = "ssh -n -F -R $port:localhost:22 -p 80";
    my $pid = fork();
       if ( $pid == 0 ) {
         exec($cmd)
         }
}

print $cgi->redirect("home.pl");

If I run this from the command line passing in the port the command executes. However, from the webpage, although the command does execute, the page stays there and doesn't redirect.
I have tried adding stdout and stderr redirection on the command but the same problem remains.

Any advise would be great!
