Limits number of accounts a single IP can create. Based on Krock's names_per_ip mod.

This mod is originating from Carbone. You don't install this mod if you're playing that particular game; it's already included and enabled by default there.

Download

No dependencies.
License for code: WTFPL


Commands

/whois <name>: gets the IP address of a player and returns all their accounts. [whois]

Settings

max_names_per_ip: limits the maximal amount of accounts. The local player (127.0.0.1) can always create as many accounts as they want. [5]

Changed privilege from “ban” to “whois”.

I have 6 people in my household including myself, all of whom play minetest to a varying extent. While it's still unlikely that my household will be affected at this point since some of the kids are not allowed to play online worlds without supervision due to their age and not everyone goes to online worlds anyway, I want to point out that my IP address has a legitimate reason to have more than 5 accounts. In several years, this could be a problem for us.

So, this isn't an important problem. It's possible to add exceptions, too.

No, it is not an important problem for me and I recognize the need to protect servers from trolls and griefers. I just wanted to point out that it could negatively affect some large households. It is good to hear that exceptions can be added.

Neat mod, Calinou! Definitely helps with the b.s. where people try to be multiple people at once just to troll.

Wuzzy, you do have some points there. You just forgot to put #endrant ;)

Please, fix this line:
Code: Select all
ipnames.name_per_ip_limit = tonumber(minetest.setting_get("max_names_per_ip")) or 5

So, I've made some little changes on the base of this fork.
Not sure if it's the correct place here but.. anyway.

Features ahead:
- Added whitelist (for players which require more than 2 accounts)
- Added timestamps to forget IPs after two weeks

Features behind:
- No "whois" privilege, it still runs over "ban"

Thanks for this mod. That saved a whole load of aggravation! :-)

Calinou, can you publish the mod on notabug or another git website (I know notabug is your favourite)? I don't like to touch zip blobs, git is better for updating and other tasks.

Just a quick question: How useful is this in a world where most people who connect to the internet with non-business accounts get a new IP address on every connect?

We use it on our server and it helps. People will keep joining with a new name to get the initial items. They put them in an unlocked chest and get a bunch of stuff.
As far as IP changing, I have had the same IP for years.

We use it on Xanadu server where you get the odd player using multiple ip's for the same name, we limit names to 3 only so if we find a player changing ip's to get more they get limited...

Sadly, there's not much we can do against dynamic IPs. It's unfair but these players can ban evade easier than those with static IPs. Using the MAC address for that would violate the privacy, so it might be better to keep it this way.

That may be like this for you. But most of the world has dynamic dial-up IPs that change with every re-connect.

It works fine Linuxdirk - your problem is theoretical, in practice most players seem to keep the same IPs. Banning players should be a last resort anyway. It is incredibly useful.

Their router would need to be turned off and on again for the IP to change (ie: reconnect.) And this probably doesn't happen much in normal houses.

Of course, there could be a power cut or a time out.

Well, at least in Germany (and almost any European countries) there is a forced reconnect every 24 hours causing a new IP address every 24 hours.

S, to answer your original question Linuxdirk, the mod works because even if the IP changes, the household will all use the same IP. So if you ban (or whitelist) by playername, their household is always affected.

The solution for this would be to ban mac addresses but that's under the cathegory "privacy" and isn't an option with the current API functions.
