[Resolved] Getting a variable from fsockopen

lmayer4

Afternoon,

I found this script to get a logon id of a person now I need to set it as a variable so I can put it in the form I've been looking at it but I can't seem to figure it out....

<?php
/
Getting netbios info
CopyLeft 2002 (GNU GPL V2) by polo
/

error_reporting(E_ALL);

/ get the ip of the client /
if (isset($SERVER["HTTP_X_FORWARDED_FOR"]))
{
$ip = $SERVER["HTTP_X_FORWARDED_FOR"];
} else {
$ip = $_SERVER["REMOTE_ADDR"];
}
echo 'ip : '.$ip.'<br>';

/ send a "special" packet /
$fp = fsockopen('udp://'.$ip, 137);
fwrite($fp, "\x80b\0\0\0\1\0\0\0\0\0\0 CKAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\0\0!\0\1");

/ wait 2 secs, and get the data /
socket_set_timeout($fp, 2);
$data = fread($fp, 256);

/ get netbios records number /
$nbrec = ord($data[56]);

/ display nebios records : the username is a record of type 3 /
echo '<table border="1">';
echo '<tr>
<th>no</th>
<th>type</th>
<th>value</th>
</tr>';
for($i = 0; $i < $nbrec; $i++) {
$offset = 18 * $i;
printf ("<tr>
<td>%02d</td>
<td>%02X</td>
<td>%s</td>
</tr>",
$i,
ord($data[72 + $offset]),
trim(substr($data, 57 + $offset, 15)));
}
echo '</table>';
?>

Thanks for any help you can provide.

You didn't say what you can't figure out, but "socket_set_timeout()" isn't a delay function. It sets the maximum time for a socket read or write operation to wait for activity. Try setting it to a higher value. Also take a look at using stream_get_meta_data() for troubleshooting.

I guess I wasn't clear. I need to somehow take the string that's put out by

for($i = 0; $i < $nbrec; $i++) {
$offset = 18 * $i;
printf ("<tr>
<td>%02d</td>
<td>%02X</td>
<td>%s</td>
</tr>",
$i,
ord($data[72 + $offset]),
trim(substr($data, 57 + $offset, 15)));
}

and put that into different variables. like machine name, loginid, ect. Is that possible?

Thanks

Found it!

<?
error_reporting(0);
exec("nbtstat -A ".$REMOTE_ADDR,$retour);
for($i = 0 ; $i <= sizeOf($retour); $i++){
if (strchr($retour[$i],"<03>")){
$tab = explode(" ",$retour[$i]);

    for ($j=0;$j<= sizeof($tab);$j++){ 
        if ($tab[$j] != ""){ 
            $Mot[] = $tab[$j]; 
            break;            }else{ 
            continue;            } 
    } 
 }

}

$hote = gethostbyaddr($REMOTE_ADDR);
$NomMachine = explode(".",$hote);

for ($i=0; $i <= sizeOf($Mot); $i++){
if (strtolower($Mot[$i]) != strtolower($NomMachine[0])){
$Final[] = $Mot[$i];
}
}

$result = array_unique ($Final);
echo $result[1];
