PHP Code:

<?php

// Executes system commands
// and displays output
function docommand($command) {
$out = "=============\nOutput\n=============\n\n";
  if (!($p=popen("($command)2>&1","r"))) {
    return 126;
  }

  while (!feof($p)) {
    $line=fgets($p,1000);
    $out .= $line;
        $out .= "<br>";
  }
  pclose($p);
  return $out;
}

$command = "netstat -a -n";

echo docommand($command);
// This command executes whatever
// is inside $command, and then
// displays ALL of the output of that
// specific command
// for your app just make
// $command = "yourapp.exe -parameters";

Note: This command will work on both linux and win32 machines

thank you, but i was wondering is there any way to pass the command options, like the ip address of the master server is added to the program by passing the program the -s 131.238.x.x option. Is there anyway to do that, and anyway to send an end signal to the program like a ctrl ^c from the linux command line, and make it an option button?

As for CTRL^C and whatnot, im not really sure what you would do, but this command doesnt leave programs running, it displays output after the program has closed, so if you have an infinite loop, you will never see output, infact, the page will never stop loading. you would have to make some sort of service
and use start and stop commands, and make a graphical web
interface to send the service commands

how does cpanel do it where it loads the script and provides hte output as the script does. or for that matter the tracert/ping scripts I see.

proc_open() i believe, but im not sure, i know the code i pasted above will work on *nix machines, so u can use that.
