Hal9000 suggested this. It's a simple modification to detect users with more than one login. As each new login is detected a PM will be sent to all administrators with information on the multiple identity users. <br /> <br /> <br />Update: Cookie uses configured expiration time and does not expire in 24 hours. Also, there is no on the number of identities tracked per user. As each new identity is used it is reported. <br /> <br /> <br />File's attached. <br /> <br />Happy Hunting. It's open season. <img src="/forum/images/graemlins/smile.gif" alt="" /> <br /> <br /> <br />UPDATED: 4-15-03 by JoshPet - Added a step to expire the cookies for Admins. Otherwise, even though the cookie isn't set if you are an Admin, you get one when you use the "become this user feature". So as soon as you become 2 users... you start getting "Multiple Identity Detected" PMs out the ying yang. This update will prevent that. <img src="/forum/images/graemlins/smile.gif" alt="" /> Hope JustDave doesn't mind me updating his code. <img src="/forum/images/graemlins/wink.gif" alt="" />

Good work Dave... except there's no file. <img src="/forum/images/graemlins/wink.gif" alt="" /><br /><br />You have been a busy beaver tonight. <img src="/forum/images/graemlins/smile.gif" alt="" />

I deleted it because one of the brackets didn't line up. Call me picky. LoL <img src="/forum/images/graemlins/wink.gif" alt="" /> <br /> <br />PS it should be there now and looking good. LoL

Just a note, this is installed here and we know who you are...<br /><br />LoL just kidding...<br /><br /><br />maybe...<br /><br /><br />LoL <img src="/forum/images/graemlins/wink.gif" alt="" />

We have ways of making you talk. Muhahahaha <img src="/forum/images/graemlins/smirk.gif" alt="" />

Cool one I tested and works perfectly. <br /> <br />JustDave is da man!! <img src="/forum/images/graemlins/applause.gif" alt="" />

Very <img src="/forum/images/graemlins/cool.gif" alt="" /> !<br /><br />Thanks! <img src="/forum/images/graemlins/smile.gif" alt="" />

hehe... updated it already. <img src="/forum/images/graemlins/smile.gif" alt="" />

this is soooo sweet. i know my inbox will be fillin up monday morning.<br /><br />is it just me or is it harder to track down multiple users via IP in threads than it was in classic...?

Only couple of hours have passed and you made this mod <br />Thaaanks

works wonderfully JustDave, thanks again

Using IIP you can match users that have the same IP address by using wild cards * in place of the . <img src="/forum/images/graemlins/smile.gif" alt="" />

I've installed this and it works -- I just found out that two sisters who post on my board must share a computer.<br /><br />Now that I know this -- and get reminded everytime one of them logs on -- is there any way to exclude member numbers from this check?

As long as they don't clear their cookies the PM's will stop. If there is no cookie one is set with the current user number. Even if you log out this cookie will remain. If they log back in under a new user the new number is added to the cookie and a PM is sent. Now that the cookie has two numbers stored it will take a 3rd new number for it to send another PM.<br /><br />I'm not sure which would be better for an ignore feature. Something from the configure file in the admin area where user numbers could be stored or to create a whole new field in the user's table and set a flag value to ignore the users with the field set.

Dave in order to limit the number of pm's everytime that recognise a multiple identity, is there any other way to report this?<br />I was thinking of a page or a text file where all the multiple identities will be writen

<img src="/forum/images/graemlins/shocked.gif" alt="" /> I had no idea this was here. And I WAS going to actually get a few hours of sleep. Thanks Dave! <img src="/forum/images/graemlins/laugh.gif" alt="" /><br /><br />Seriously, thank you. This will really make some of our work easier. <img src="/forum/images/graemlins/smile.gif" alt="" />

This is a very cool and needed hack! <br /> <br />One strange result I got: <br /> <br />>From: **DONOTDELETE** <br />>I seem to have multiple personalities using ID numbers 1234 and 1 <br />>sharing the same computer. <br /> <br />How can it happen that some user could login as User #1 DONOTDELETE <br /> <br />Is this a bug in the hack's code or is there a user using some sort of side entrance to threads nobody was aware of yet? - By the way: I have deleted only 2 users. I am pretty sure this one was not amongst them.

[/]<br />I admin on coy's board.... so the repeated duplicate PMs from the sisters were bugging me. <img src="/forum/images/graemlins/grin.gif" alt="" /> They must toss their cookies. <img src="/forum/images/graemlins/tongue.gif" alt="" /> So I tweaked this a bit.<br /><br />So..... Here's how you can ignore certain user numbers:<br /><br />In the original double identity detection code....<br /><br />Where it says:<br /><br /><br /><br />Change to this:<br /><br /><br /><br />Then go into your config file.... at the very bottom and put this variable into the extra/unknown variable section.<br /><br /><br />$config['allowed_dupes'] = '14,17,13';<br /><br />Between the quotes... put "allowed" duplicate user numbers. Separate them with a comma. What this does... if the user number matches a number on this list, it skips the Private Message send out. <img src="/forum/images/graemlins/wink.gif" alt="" /><br /><br />Now if a user on the list has more identities than the what you list, you won't get notified. It basically ignores this user and it's assumed that they are allowed unlimited duplicates. <img src="/forum/images/graemlins/smile.gif" alt="" /><br /><br />Hope that helps. <br />Josh <img src="/forum/images/graemlins/smile.gif" alt="" /><br /><br />

I think the sisters in question login to the board from school, and that's why they share a computer which also dumps cookies on a regular basis. I'm noticing this issue quite a bit with the number of college kids on my board.<br /><br />This fix will really come in handy. There's nothing more disappointing than having a new PM then discovering it's just a "duplicate ID notification" <img src="/forum/images/graemlins/tongue.gif" alt="" />

I think a small change is needed in the code so that user number 15 won't match up to 156. Change this:<br /><br /><br /><br />Into this:<br />
