duplicate ip/password list!

and here it is, finally.. perhaps one of the sweetest hacks i've ever installed.. unfortunately i didn't write it, but wired from http://www.xirgo.com (an awesome host, btw) did, and he gave me permission to release it on here.

this is the duplicate ip/password list hack. this basically shows all duplicate accounts on your vb forum sorted by their ip and/or password. this easily allows you to detect who's really who on your forum, and delete/ban accounts that you think are duplicates.

basically it works like this. there are two parts to this list, one part sorted by duplicate ip, the other part sorted by duplicate password. you can definitely tell users have multiple accounts on your forum if you see two (or more) users both with duplicate ip's AND passwords. this list also lists their post counts and their last visit date, so, if you want to just delete one of someone's duplicate accounts, you can choose to do so by either their last visit date (delete/ban the account that hasn't been on the forum longer), or by their number of posts (delete/ban the account that has the less posts).

please note that NOT ALL duplicate pw's are duplicate accounts, obviously. any user can happen to have the same pw as someone else. i wouldn't recommend deleting people with JUST duplicate pw's, nor with JUST duplicate ip's, because of shared accounts on the same connection, etc., but they can definitely be fishy.

to install this hack, simply put the dupeip.php file into your /admin directory of your vb forum. then to access it, go to yoursite.com/forum/admin/dupeip.php, of course.. that's it! no templates to install, no files to modify!

NOTE: the passwords on the list are in their VB encrypted form, but to be safe, only show this list to the other admins of your forum, although by putting it in your /admin folder it will ask for an admin login anyway.

is it just me or has anyone else noticed that if you click the duplicate passwords link it brings up the list of doupe IP's and then the doupe passwords as well instead of just the doupe passords list alone?

Added if a user can post to the outpout, a remove link, an admin header footer, and a reverse lookup of the ip addresses. if you are interested feel free to download it. It did not take much time but might help some of those of you who don't have time to add these things.

To integrate this into the control panel, I did the following:

Open admin/index.php
Find:

makenavoption("IP Addresses","user.php?action=doips","<br>");

Add AFTER it:

makenavoption("Duplicate IPs & PWs","dupeip.php?action=","<br>");

Open admin/dupeip.php
Find:

require("./global.php");

Add AFTER it:

if (isset($action)==0) {
  $action="modify";
}

Awesome hack. Love it!!!!

I got this error in control panel...

Warning: Address is not a valid IPv4 or IPv6 address in /home/virtual/site17/fst/var/www/html/admin/dupeip.php on line 74

Yes, I have IP loggin enabled.

Any help would be appreciated.

Thanks!

This only checks the IPs used to register? That is not nearly as helpful as checking it against ALL the IPs a user uses. Many people get on the internet at work and have atleast 2 IPs. Heck I just did a search on the IPs I've used and I've used 24. So basically this hack has a 1 in 24 chance in stopping me. Good hack however I think it can be improved.
