Gots another question.

[Scrubby]

Can two people have the same static IP when they're from the same ISP?

[rylin]

The short answer: yes.
A longer answer would be detailing that they could be behind a NAT, making it appear as if they're from the same IP.

It all depends on how the ISP hooks everything up really.

[Scrubby]

Point taken. Now here is my big big question. :D.

On a forum I moderate, we have two users with the same IP from the same ISP. At first, I didn't think anything of it, until I started watching the who's online list for about 30 minutes. To my suprise, when one stopped being active, a guest then showed up, when the guest disappeared, the other member showed up. And it also went the other way around. It kept going like this until I confronted the person. I got the excuse that they're cousins.

But what got me was with all that logging in and logging out for 30 minutes between these two users. They could be behind the same computer, but why would one mnake a thread to ask one of them to turn on their PM's, if they are behind the same computer.

This oh so confusing. What should I do? :(. We're going to upload a few hacks from vB.org to dig more into this and find out what really is going on, but I jsut wanted all your opinions.

Edit: One of them is a mod, while the other one is not. Now why would the one who is not a mod, make a suggestion to the admin to make a private forum for Admins and Mods only?

That was what made me start getting curious.

[rylin]

Which isp are "they" using?

[Scrubby]

They're using shawcable services. That is what the host thingy ma bob on vB said. :eek:

[rylin]

Then I'd say it's safe to say it's the same person,
unless the hostname indicates that it's a web cache / proxy.

Although, shaw have business services as well as private services..
If they work at the same company, they're most likely behind a NAT, and it'd look like they have the same static ip.

If you want to make sure though, you could write up a little something that checks for a cookie version of the userid (eg a cookie named oldbbuserid, and if the current oldbbuserid isn't blank, but differs from the current bbuserid, an email gets sent to you)..

[Scrubby]

How would I go about writting up something like that? If you do not feel like posting it, could PM it to me? :D

[rylin]

something along the lines of

<?php
include 'global.php';
global $bbuserinfo;
if($_COOKIE['oldbbuserid']) {
if($_COOKIE['oldbbuserid'] != $bbuserinfo['userid']) {
mail("your@e.mail","Bad oldbbuserid cookie","The stored cookie: $_COOKIE[oldbbuserid] differs from the current bbuserid: $bbuserinfo[userid]");
}
} else {
// set the cookie
setCookie('oldbbuserid', $bbuserinfo['userid'], time() + 86400);
}
?>


just put that in eg. cookieCheck.php and include it in global.php like include "cookieCheck.php";

make sure there's no spaces before or after the php tags in cookieCheck.php though :)

note, it's untested, so you might want to try it on yourself first ;)

[Scrubby]

Okay, so I add the first part to a new file called cookieCheck.php and add the second part to the root/global.php and it may work? :D

[rylin]

yeap, in theory it should work ;)
like i said though, test it on yourself first :o

[Scrubby]

Okay. :). Off to test it on my site at the moment. :p. Be back with the results. :)

[rylin]

actually, if you're not using one of the newer versions of php where the super-global arrays exist ($_COOKIE, $_GET etc), you'll want to add the following after global $bbuserinfo;

global $HTTP_COOKIE_VARS;
$_COOKIE = &$HTTP_COOKIE_VARS;

:eek:

[rylin]

change the include string to

include "./cookieCheck.php";

[Scrubby]

Still getting the errors. :(

[rylin]

erm, i think i'm a bit stupid here.. 2am does that to people :P
making cookieCheck.php include global.php which includes cookieCheck.php.... whee! loop! ;)

sorry about that :o

remove include 'global.php'; from cookieCheck.php ;)

if it still doesn't work, just place the code from cookieCheck.php at the bottom of global.php

:blush:

[Scrubby]

Adding it to the end of global.php worked! Now time to test. :D

[rylin]

/me watches as Billy's forums explode

[Scrubby]

Good god. I just got spammed to hell by adding that. LMAO! :D.

But what does this mean?
The stored cookie: 39 differs from the current bbuserid: 1

Does that mean that the user 39 is using the other account? :D

[rylin]

it means that you were logged on with userid 39, and then logged in with userid 1 ;)

just realized.. you might want to add another

setCookie('oldbbuserid', $bbuserinfo['userid'], time() + 86400);

after

mail("your@e.mail","Bad oldbbuserid cookie","The stored cookie: $_COOKIE[oldbbuserid] differs from the current bbuserid: $bbuserinfo[userid]");

[Scrubby]

Thanks for the help okidoki. :)

[rylin]

np :)
