output/ directory doesn't exist. server.php needs the output directory to exist

Traceroute Mesh Server
Traceroute Mesh Server
By Perry Lorier
Your host cannot be added to the set of tr drones:
\n";
foreach($error as $msg) {
echo "
$msg\n";
}
echo "";
}
?>
Note: Traceroutes may take a couple of minutes to complete, please be patient.
The full mesh picture will be large, scroll around to see the full thing.
