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:
-------------------------------------------------------------------------------------------------------------

<?php
$_ip = $_SERVER['REMOTE_ADDR'];
echo "<b>Enter the IP or the domain name of the server that you are trying to ping.</b><br>";
echo "<form method='post' action='ping.php?do=ping'><input type='text' name='domain' class='input_login' value='$_ip'>&nbsp;<input type='submit' value='Ping' class='input_login'></form>";
if($_GET['do'] == 'ping')
{
$_domain = $_POST['domain'];
        echo "<pre>";
                    //system ("tracert $_domain");
                   system ("ping $_domain -n 5");
 
 
          echo "</pre>";
}
echo "<br>";
 ?>

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 :) )

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.readline()
        if not line: break
        igot = re.findall(testit.lifeline,line)
        if igot:
           self.status = int(igot[0])
 
testit.lifeline = re.compile(r"(\d) received")
report = ("No response","Partial Response","Alive")
 
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()

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

Merci/Charlie
