socket_connect

I’ve switch from Windows 2003 server to 2008 server 64-bit. I’ve been able to fix most things but socket_connect is still giving me trouble. Here is the code:
[php]class Net_Ping
{
var $icmp_socket;
var $request;
var $request_len;
var $reply;
var $errstr;
var $time;
var $timer_start_time;
function Net_Ping()
{
$this->icmp_socket = socket_create(AF_INET, SOCK_RAW, 1);

}

function ip_checksum($data)
{
for($i=0;$i<strlen($data);$i += 2)
{
if($data[$i+1]) $bits = unpack(‘n*’,$data[$i].$data[$i+1]);
else $bits = unpack(‘C*’,$data[$i]);
$sum += $bits[1];
}

 while ($sum>>16) $sum = ($sum & 0xffff) + ($sum >> 16);
 $checksum = pack('n1',~$sum);
 return $checksum;

}

function start_time()
{
$this->timer_start_time = microtime();
}

function get_time($acc=2)
{
// format start time
$start_time = explode (" “, $this->timer_start_time);
$start_time = $start_time[1] + $start_time[0];
// get and format end time
$end_time = explode (” ", microtime());
$end_time = $end_time[1] + $end_time[0];
return number_format ($end_time - $start_time, $acc);
}

function Build_Packet()
{
$data = “abcdefghijklmnopqrstuvwabcdefghi”; // the actual test data
$type = “\x08”; // 8 echo message; 0 echo reply message
$code = “\x00”; // always 0 for this program
$chksm = “\x00\x00”; // generate checksum for icmp request
$id = “\x00\x00”; // we will have to work with this later
$sqn = “\x00\x00”; // we will have to work with this later

// now we need to change the checksum to the real checksum
$chksm = $this->ip_checksum($type.$code.$chksm.$id.$sqn.$data);

// now lets build the actual icmp packet
$this->request = $type.$code.$chksm.$id.$sqn.$data;
$this->request_len = strlen($this->request);
}

function Ping($dst_addr,$timeout,$percision)
{
// lets catch dumb people
// if ((int)$timeout <= 0) $timeout=5;
// if ((int)$percision <= 0) $percision=3;

// set the timeout
socket_set_option($this->icmp_socket,
SOL_SOCKET, // socket level
SO_RCVTIMEO, // timeout option
array(
“sec”=>$timeout, // Timeout in seconds
“usec”=>0 // I assume timeout in microseconds
)
);

if ($dst_addr)
{
if (@socket_connect($this->icmp_socket, $dst_addr, NULL))
{

 } else {
   $this->errstr = "Cannot connect to $dst_addr";
   return FALSE;
 }
 $this->Build_Packet();
 $this->start_time();
 socket_write($this->icmp_socket, $this->request, $this->request_len);
 if (@socket_recv($this->icmp_socket, &$this->reply, 256, 0))
 {
   $this->time = $this->get_time($percision);
   return $this->time;
 } else {
   $this->errstr = "Timed out";
   return FALSE;
 }

} else {
$this->errstr = “Destination address not specified”;
return FALSE;
}
}
}[/php]

What problem(s) is it giving you?

I sniffed the line and the pings are never leaving the server. The code is running and I get a response that the devices are not pingable, even though they are.

Just to check, are sockets enabled on the PHP configuration?

I wasn’t sure but I looked and it is (php_sockets.dll Enabled).

Have you got all errors turned on? Any appear?
