I need to know how you can find and ban MAC addesses on my PHP game. I need to know so admins and mod can do it. Like IP banning.

It's not really possible with PHP to get the MAC address of a remote users machine.

Funnily enough, I run a browser based game (see my sig) and I have the ame probem, banning users is hard - you can do it by IP, ip range, or even by ISP.. but each one of those exludes a large group of players than you will want to exclude.

Its a problem for online games and the only solution I can suggest is good, active ingame moderation.

All the best,

I talked to a pro. He said it was possible, but he didn't know how to do it.

I'm a PHP software developer, for a living - have been for years

It is not possible.. or atleast if it is then it's news to me and I will accept it when I see it and learn from it

MAC addresses arent part of the TCP/IP layer as far as I'm aware? And PHP cannot get info from a remote users machine regarding hardware, only software - so yeah, its not possible. Sorry

Sir P is correct. You can only get a MAC address from a computer on the same subnet as you. You would need to do an arp request and these are generally not relayed beyond the local subnet as it's a layer 2 activity.

So basically, unless you've got your users on the same subnet as your webserver, it's not possible.

My english isn't that good, so when I say subnet, I mean same physical network, like a LAN or such. No routers or gateways inbetween clients and server.

By the way, I've just looked at your "xyber wars" game, nice! All your own work? Do you do freelance stuff?

Cool, Thanks guys.

you can banned only ip address
