Check the hosts that can be accessed via the icmp protocol.

[carlos villanue]

I have to Check the hosts that can be accessed via the icmp protocol. Displays all the IP in a table.
Add one more field to the table to indicate if these hosts is reached, the time to access these hosts.
Sorry if my English is not good.

This is what I have done, but I don't know how to continue:I get the ips and if yo access or not. But I dont know how to get the time
Thanks for your help

<?php
echo "<table border='1'>";
for ($i=1;$i<=254;$i++) {
 
$IP = '10.10.120.'.$i;
$comando = 'ping 10.10.120.' . $i. ' -n 1';
$ejecucion = popen($comando,'r');
 
$accesible='si';
while (!feof($ejecucion)) { //while not end of file($ejecucion)
$linea = fgets($ejecucion);
$campos = explode('inaccesible',$linea);
if (count($campos) == 2) {
$accesible='no';
}
}
echo "<tr> <td> $IP </td> <td> $accesible </td> </tr>";
 
}
echo "</table>";
 
?>

I continue trying to get something

When I do each one separately I can see.

Count ($ field == 8) gives me the time and if I Count ($ field == 2), I see if it is accessible or not.

The problem is to bring the two together to see all the information in a table
(IPS, times, yes or no)

<code>

<?php
echo "<table border='1'>";
for ($i=220;$i<=254;$i++) {

$IP = '10.10.120.'.$i;
$comando = 'ping 10.10.120.' . $i. ' -n 1';
$ejecucion = popen($comando,'r');

$tiempo=microtime(); //'timestamp';
while (!feof($ejecucion)) { // mientras no sea el final del archivo($ejecucion)
$linea = fgets($ejecucion);
$campos = explode('tiempo',$linea);

if (count($campos) == 8) {
$tiempo='timestamp';
}


/* $accesible='si';
if ($count($campos)==2) {
//while (!feof($ejecucion)) { // mientras no sea el final del archivo($ejecucion)
//$linea = fgets($ejecucion);
//$campos = explode('inaccesible',$linea);
//if (count($campos) == 2) {
$accesible='no';
} */


//}************************************************* *******/

}
echo "<tr> <td> $IP </td> <td> $tiempo </td> </tr>";
// echo "<tr> <td> $IP </td> <td> $tiempo </td> <td> $accesible</td> </tr>";

}

echo "</table>";
?>
