While trying to find more Mobotix cameras using Google, I quickly ran out of search results to check out. But I knew there had to be more out there that Google just isn't finding.
I decided there must be a simple script you could run that searches for URL's that match a particular search string (just like Google does). But you could have it search a particular range of IP's, routinely checking one for the search string.
It wouldn't be pretty or efficient of course, but it would be simple and I could probably code it.
Let me preface this by saying, I'd never coded in PHP before, which might already be obvious.
So, my little PHP search script looks like this:
You enter an IP address (minus the last 3 digits). This of course means that the search range is very limited.
Then you enter the IP range you want it to search. In the example above the IP's searched are:
216.172.100.1 through 216.172.100.80.
Then you enter a filename for the script to save its results to. If any valid IP's have a url that matches the search string, their header information is written to the file.
Like I said, it is very limited in what it can do, but not bad for my first PHP script, written on the fly. It's a starting place for anyone who wants to expand on it.
Here is the code. It's broken up into two files.
index.php
<html>
<head>
<title>IP Check</title>
</head>
<body>
<a href ="index.php">Home</a>
<p>IP Check<p>
<p>
IP format XXX.XXX.XXX. (ex. 70.147.100.)<p>
X = lower number<p>
max = upper limit <p>
Filename to write to.<p><p><p>
<form action="camcheck.php" method="post">
Enter IP: <input name="ip" size="12"><p>
Enter X: <input name="x" size="3">
Enter Max: <input name="max" size="3"><p>
Filename: <input name="myfile" size="20">
<input type="submit" value="Start">
</form>
<p>
<img src="magnify.jpg" alt="magnify"/>
<?php
?><p><p>
</body>
</html>
The index file is basically just a bunch of html text boxes. The info captured is then used by the second file.
camcheck.php
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>

<head>
<title>IP Check</title>
</head>
<body>
<?php
$path = "/control/userimage.html"; // url search string
$myFile = $_POST['myfile'];
$fh = fopen($myFile, 'w') or die("Can't open file"); //open file
for ($x =(int)$_POST['x']; $x <= (int)$_POST['max']; $x++)
{
$url= $_POST['ip'].strval($x);
//echo $url;
$valid = @fsockopen($url, 80, $errno, $errstr, 4); //check url
if (!$valid) {
// Output Error Message, if you care
// echo '<p>not valid<p>';
//echo "$errstr ($errno)<br />\n";
//$returnstring = $url." Not Valid $errstr ($errno)> \n
//$returnstring = "X = ".$x;
//fwrite($fh,$returnstring);
}
else {
// Output Success Message!
fputs($valid, "\nHEAD $path HTTP/1.1\r\nHost: $url[host]\r\n\r\n"); //socket opened
$headers = fread($valid, 4096);
$returnstring = "\n".$url." Valid\n";
fwrite($fh,$returnstring); //write valid IP to file
fwrite($fh,$headers); //write header info
fwrite($fh,"\n");
}
}
echo "\n Program Complete. Results sent to ".$myFile;
fclose($fh);
?>
<p><p>
</body>

</html>
In the camcheck.php file, you'll see that the url search string is hard-coded into $path. It would probably be easy to make that another textbox, so you can change what url string to search for.
"/control/userimage.html" is a typical Mobotix web cam url. Which is what I created the script to find.
When you run the script, it saves the header results to a file on your webserver.
Here are some example results:

I find it interesting just reading the different headers, and learning what they mean. You get an idea of what sites are located in certain IP's.
I haven't played with the script much, but I think it could be even more fun with some minor tweaks.
Right now it won't let me search more than 100 at a time before timing out. I haven't tried fixing that just yet.
Let me know if you have any hints/tips/fixes. I'd love to hear them.
