merci beaucoup, mais ce code demande d'avoir les droits administrateurs, sinon il a l'air de marcher car il ne bloque qu'a l'ouverture du socket(les paramètres ne sont pas les même quand j'utilise cette fonction habituellement, donc c'est surement un des paramètres qui nécessite d’être administrateur).
EDIT: je vient d'utiliser un autre code, même résultat opération non permises.
Ce code :
Code : Tout sélectionner
<?
$g_icmp_error = "No Error";
// timeout in ms
function icmpChecksum($data)
{
$bit = unpack('n*', $data);
$sum = array_sum($bit);
if (strlen($data) % 2) {
$temp = unpack('C*', $data[strlen($data) - 1]);
$sum += $temp[1];
}
$sum = ($sum >> 16) + ($sum & 0xffff);
$sum += ($sum >> 16);
return pack('n*', ~$sum);
}
function getLastIcmpError()
{
global $g_icmp_error;
return $g_icmp_error;
}
function ping($host, $timeout = 3, $port = 0)
{
$datasize = 64;
global $g_icmp_error;
$g_icmp_error = "No Error";
$ident = array(ord('J'), ord('C'));
$seq = array(rand(0, 255), rand(0, 255));
$packet = '';
$packet .= chr(8); // type = 8 : request

$sock = socket_create(AF_INET, SOCK_RAW, getprotobyname('icmp'));
$time_start = microtime();
socket_sendto($sock, $packet, strlen($packet), 0, $host, $port);
$read = array($sock);

$select = socket_select($read, $write, $except, 0, $timeout * 1000);
if ($select === NULL)
{
$g_icmp_error = "Select Error";
socket_close($sock);
return -1;
}
elseif ($select === 0)
{

socket_close($sock);
return -1;
}
$recv = '';
$time_stop = microtime();
socket_recvfrom($sock, $recv, 65535, 0, $host, $port);

if ($recv[10] !== 1) // ICMP proto = 1
{

socket_close($sock);
return -1;
}
if ($recv[21] !== 0) // ICMP response = 0

socket_close($sock);
return -1;
}
if ($ident[0] !== $recv[25] || $ident[1] !== $recv[26])

?>
et celui ci :
Code : Tout sélectionner
<?
function ping($host) {
$package = "\x08\x00\x19\x2f\x00\x00\x00\x00\x70\x69\x6e\x67";
/* create the socket, the last '1' denotes ICMP */
$socket = socket_create(AF_INET, SOCK_RAW, 1);
/* set socket receive timeout to 1 second */
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array("sec" => 1, "usec" => 0));
/* connect to socket */
socket_connect($socket, $host, null);
/* record start time */
list($start_usec, $start_sec) = explode(" ", microtime());
$start_time = ((float) $start_usec + (float) $start_sec);
socket_send($socket, $package, strlen($package), 0);
if(@socket_read($socket, 255)) {
list($end_usec, $end_sec) = explode(" ", microtime());
$end_time = ((float) $end_usec + (float) $end_sec);
$total_time = $end_time - $start_time;
return $total_time;
} else {
return false;
}
socket_close($socket);
}
donne le même résultat, une erreur de permissions.
