Track all Duplicate IP Addresses via Admin CP (by Jolten)

This is a port from the 3.0.7 version by Jolten. He doesn't plan to upgrade to 3.5, and I do, so I'm releasing it for 3.5 with his permission:

Be aware that many internet service providers (AOL, JUNO, NetZero) may assign the same IP to many different users. A duplicate listing is not an immediate indication of a duplicate account by the same user.

Wonder if it possible to (extend the hack to) check for dupips when the "base" members belong to a particular user group... eg, i have a banned group, and i want to make sure none of them is registering using pseudo ids. tough to go thru the entire list... ?

Yes, shouldn't be that hard. Feel free to bump if you don't hear from me in a week or so

I have this installed and the extra IP information hack installed. https://vborg.vbsupport.ru/showthread.php?t=96834

The extra IP information hack shows other users that have used the same IP but those users don't show up in the duplicate IP information in the admincp. Does the duplicate IP hack only check the IP that shows up under the user manager in the admincp and if so could it check all the IPs a user has used to add them to the duplicate IP address list?

You will get that info when you click the IP link. Otherwise, the list would be too long, since some users have dynamic IP's, and it would take several pages just to display one user.

thanks tamarian..

think there is a bug in the latest version in that it only searches the chosen "primary" member group, not all groups for duplicates...

for eg, if i have a "banned" group, i would like to search for all banned members who might have created other accounts in "regular" groups...

TIA.

I know it'd be next to impossible, but it'd sure be nice to filter out AOL proxy's. They make up 80% of my duplicate posts.

Or better yet, just filter by date. If they haven't posted in X days, it won't show up?

tamarian;

Great hack! Works beautifully on vb 3.5.1! One small note: In the AdminCP the title is mispelled, see attached image. Other than that, it works great!

Under one of the older DupeIP mods for vB2, the script also had the ability to list duplicate passwords (albeit the encrypted output only for security). I found this more useful for spotting multiple accounts since people like that tend to use an identical password, would it be possible to add this as an option?

I remember the vB2 version. (I think) it's impossible to do with vB3.x, due to the introduction of "slat" to md5 of the password.
