how to measure the ping time between the visitor and my website ??

hello !

I would like to measure the time a user needs to connect to my website.
In other words, to perform a ping between my website and the user's
computer.

I'm scratching my head as to how i can do that. Does anyone know a good way
to make this happen?

thanks a lot,

alexandre

Here you go
<?
$ip = $_SERVER['REMOTE_ADDR'];
$res = `ping -c 1 $ip`;

list($n,$r) = explode("packet loss, ",$res);
list($pTime,$n) = explode("ms",$r);
print "Ping time $pTime ms";
?>

you can test it here:
http://gzen.myhq.info/test/ping.php


Ok, now several things wrong with this, first, this will only work if ping
packets are allowed through the entire netork from you to them, inside thier
network if they are in say a corporate building. Now if they are behind a
firewall, you will only get times to the firewall. (depends on firewall, but
most likely, firewall times)

Now, this also assumes they dont have any type of stupid software like
black-ice, (sorry to offend, but if you have a software firewall installed
on the machine you are trying to protect, your an idiot, get a solution
before the machine you are protect!) -- ok sorry about that

Also, the route that someone uses to send packets to you is not nessasarily
the route the packets take from you to them. For example. At one of my data
centers, outgoing data is routed through the least congested pipe.

re: how to measure the ping time between the visitor and my website ??

thanks a lot mike.

I'm gettting 0 ms all the time. Is that normal ?
Also, would this work on a virtual server? I heard Virtual servers don't
let you execute commands with php, as you could use it to execute "rm -rf /"
or other bad things. So, they set this in their php.ini.
What do you think ?

thanks again,

alexandre
PS: nice website :)

re: how to measure the ping time between the visitor and my website ??

The test on my server, is a virual host, I have around 65 virtuals on that
server
rm -fr will only work on files that are the same owner/group permission


as far as 0ms, not sure, you must be realy, realy, close to me, but I didnt
see you at the office coffee maker :)

i assume you are talking about the chmod parameters. i'll experiment with
that and see what happens.

re: how to measure the ping time between the visitor and my website ??

on my virtual server, i don't even get the "0" ms. it just returns "Ping
time ms".
i tried different chmod configs, with same owner/group params, to no avail.

hmm, I will look into this a bit, becouse it was raised some questions/ideas
in my head.
what can you tell me about the server, OS, httpd server (apache?), versions
etc??

(I turned around, and I saw you walk out to get check your server info, I
must say, that is a nice sweater your wearing, holiday x-mas gift?)

try this:
you can test it here: http://www.gzentools.com/test/ttouser.php or
http://gzen.myhq.info/test/ttouser.php

<?php
$ip = $_SERVER['REMOTE_ADDR'];
$s = microtime();
$fp = fsockopen("tcp://$ip", 1, $errno, $errstr);
$e = microtime();

$tt = $e-$s;

if ($fp)
fclose($fp);

print "Trip time: $tt ms\n";

?>

This tries to open a socket connection to the users machine (or firewall, as
I stated before), to port 1, which should not be open, if it should open, it
will close the connection, either way, it will time the proccess, since this
is not ping, we are only talking about a slight differnce of a few
milliseconds, so does it matter?

we can call this Fuzzy Ping ;)

wow, i 'm impressed ! it works !!
thank you so much for lending out your skills to me.
i'm sure your script could be useful to many people outthere, because there
is nothing available as such online. could you add it on your site?

have a good good good one, if you want, you can have my tiger string (or,
what's left of it, new year 's eve was wild )

Blushing I am, Thank you.

I am glad it worked for you. Yea, new years was wild, I ws flinging code to
finishup my encoder, it kept breaking when people tried to use the encoded
scripts. I tend to like to solve problems, and cant let them go untill I
find a solution.

I will add it to my site, within the next few minutes. I will clean it up a
bit and call it FuzzyPing ;)

re: how to measure the ping time between the visitor and my website ??

At which point in your script is the ping command executed?

I assume this question is to me on this piece of code?[color=blue][color=green]

it is the line $res = `ping -c 1 $ip`; $res = to output of command ping -c
1 $ip

the back ticks ` or backwords single quotes lets you execute a shell
command, its a carry over from perl
I use it alot, since I tend to write most of my shell scripts on PHP now
days.

FYI, PHP shell scripts, first line: #!/bin/php -q

BTW, I posted the fuzzyping
