Just a follow-up to myself... I decided to try packet sniffing to see
what was going on and ettercap confirms that I'm sending out strings
rather than data of the type stored in my array:
16:12:26 192.168.0.101:32779 --> 192.168.0.88:32896 | UDP |
0000: 3331 31
That "31" should be an integer of only one byte, not two.
The function that's doing the sending looks like this:
function send_back($sock, $msg, $ip, $port) {
$fp = fsockopen("udp://$ip", $port, $errno, $errstr);
foreach ($msg as $msg_to_send) {
fwrite($fp, $msg_to_send);
echo date("H:i:s")." SENT '$msg_to_send'\n"; //seen server
side
}
fclose($fp);
}
Can anyone see where I might be going wrong? Why am I not sending the
integers as integers and the binary bits as binary bits?
