PHP visit DOS system command

[Charlie of Bolton]

Hello everyone,

I want to start a ping on my IP number one, but if this first ip is timing out, I want my script to start automatiquely the check 3 other IP simultanously for comparaison.

Of course I want the result of the packet lost % to be shown for each of my IPs and that timed out time. What will be your best guest to built such a tool. I`m using PHP 4.x and MySql 4.0 and Windows XP.

What do you suggest me. »Thanks

Here is my basic PHP system script and works perfectly:
-------------------------------------------------------------------------------------------------------------
[code=php]<?php
$_ip = $_SERVER['REMOTE_ADDR'];
echo "<b>Enter the IP or the domain name of the server that you are trying to ping.</b><br>";
echo "<form method='post' action='ping.ph p?do=ping'><inp ut type='text' name='domain' class='input_lo gin' value='$_ip'>&n bsp;<input type='submit' value='Ping' class='input_lo gin'></form>";
if($_GET['do'] == 'ping')
{
$_domain = $_POST['domain'];
echo "<pre>";
//system ("tracert $_domain");
system ("ping $_domain -n 5");


echo "</pre>";
}
echo "<br>";
?>[/code]

Hmmm,
Sorry man, there is no current support in php for +multi+threadin g. But i can suggest you a nice alternative in python. Obviously you can use it just if you create a socket server (if you want that someone else can use your service) and an access sql with the module sqllite(raccome nded :) ). But with those kind of service you have to pay attention to your cpu load!

PYTHON CODE(yes, i know i am in the php session :) )
[CODE=python]
import os
import re
import time
import sys
from threading import Thread

class testit(Thread):
def __init__ (self,ip):
Thread.__init__ (self)
self.ip = ip
self.status = -1
def run(self):
pingaling = os.popen("ping -q -c2 "+self.ip," r")
while 1:
line = pingaling.readl ine()
if not line: break
igot = re.findall(test it.lifeline,lin e)
if igot:
self.status = int(igot[0])

testit.lifeline = re.compile(r"(\ d) received")
report = ("No response","Part ial Response","Aliv e")

print time.ctime()

pinglist = []

for host in range(60,70):
ip = "192.168.200."+ str(host)
current = testit(ip)
pinglist.append (current)
current.start()

for pingle in pinglist:
pingle.join()
print "Status from ",pingle.ip,"is ",report[pingle.status]

print time.ctime()
[/CODE]

Thanks, I will take a look in Python and your ref web site.
I appreciated your reply.

Merci/Charlie
