echo '<title>Port Availability Checker';
//Please leave the next line :)
echo ', Writen by Jonesy44';
echo '</title>';

$addr = $_SERVER["REMOTE_ADDR"];
$port = "80";
if ($_GET["addr"]) {
$addr = $_GET["addr"];
}
if ($_GET["port"]) {
$port = $_GET["port"];
}
if ($_GET["port2"]) {
$port2 = $_GET["port2"];
}


echo '<form action="' .$_SERVER["PHP_SELF"]. '" method="get">
<div style="width:300px;background:#f1f1f1;padding:10px;font-family:arial;">

<td width="80%"><input type="text" name="addr" value="' .$addr. '"></td>

</div>
</form>
';

if ($_GET["addr"]) {
if ($_GET["port"] && !$_GET["port2"]) {
$fp = @fsockopen($addr, $port, $errno, $errstr, 2);
$success = "#FF0000";
$success_msg = "is closed and cannot be used at this time";
if ($fp) {
$success = "#99FF66";
$success_msg = "is open and ready to be used";
}
@fclose($fp);
echo '<div style="width:300px;background:' .$success. ';padding:10px;font-family:arial;font-size:12px;">
The address <b>"' .$addr. ':' .$port. '"</b> ' .$success_msg. '
</div>';
}
else if ($_GET["port"] && $_GET["port2"]) {
$p1 = $_GET["port"];
$p2 = $_GET["port2"];
if ($p1 == $p2) {
$fp = @fsockopen($addr, $port, $errno, $errstr, 2);
$success = "#FF0000";
$success_msg = "is closed and cannot be used at this time";
if ($fp) {
$success = "#99FF66";
$success_msg = "is open and ready to be used";
}
@fclose($fp);
echo '<div style="width:300px;background:' .$success. ';padding:10px;font-family:arial;font-size:12px;">
The address <b>"' .$addr. ':' .$port. '"</b> ' .$success_msg. '
</div>';
}
else {
if ($p1 < $p2) {
$s = $p1;
$st = $p1;
$e = $p2;
}
else if ($p2 < $p1) {
$s = $p2;
$st = $p2;
$e = $p1;
}
while ($s <= $e) {
$fp = @fsockopen($addr, $s, $errno, $errstr, 1);
if ($fp) {
$p_open = $p_open. " " .$s;
$p_1 = 1;
}
@fclose($fp);
$s++;
}
if ($p_1) {
$c = "#99FF66";
$m = "On the address <b>" .$addr. "</b> and port range <b>" .$st. "-" .$e. "</b> the following ports were open: " .$p_open;
}
else {
$c = "#FF0000";
$m = "No ports on the address <b>" .$addr. "</b> and port range <b>" .$st. "-" .$e. "</b> were open";
}
echo '<div style="width:300px;background:' .$c. ';padding:10px;font-family:arial;font-size:12px;">' .$m. '</div>';
}
}
}

this works partly on my wamp server but shows errors
it fails horibly on the free server but no errors

i m no big scripter or anything but maybe fsockopen is not allowed?

The script works for me (after adding <?php tag to start )\\

Also, try testing if a function exist and if it is working properly:

Code:

<html>
<head><title>TESTING</title></head>
<body>

<?php

$fun = 'fsockopen' ;

// TO SEE IF THE FUNCTION EXITS

if( function_exists( $fun ) ){
   echo "$fun exists";
} else {
   echo "$fun does not exist";
}

// HARD CODE THE INFORMATION AND TEST JUST ONE FUNCTION

$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {
    $out = "GET / HTTP/1.1\r\n";
    $out .= "Host: www.example.com\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    while (!feof($fp)) {
        echo fgets($fp, 128) . "<br \>";
    }
    fclose($fp);
}
?>
</body>
</html>

php tags are there sorry that was not in the example i used to copy from

yes it may look like it works fine (like i said it shows no error)
but from what i see the outcome cannot be right

i must admit i wouldn t know where to start on testing a function that s why i popped the question :laugh:

but thnx for your reply sofar ;)

EDIT: reading better i spotted the hint lol, sorry ....and thnx i will try this
Edit:
probably automerged as an edit:

the test was positive yes, hmmm i ll play around with it some more, because i still don t trust the portcheck's outcome to be correct:dunno:
