-=*MAC Address Ban*=-

Which hub software is the best? Where can I find script XXX? Discuss it here...(no, this is not for advertising your hub...)

Is there any script wich bans the users MAC address? It would be extremly usefull and the user can be "stronger" banned...

AFAIK there is no way to find out the users mac address, unless he runs a service that exposes it.

if you try to get an arp-reply from someone beyond your subnet, you'll get the MAC address of the gateway/bridge that connects your subnet with the rest of the internet.

(correct me if I'm wrong here)

finding the MAC adress through any type of router is technically impossible

NetBIOS over TCP/IP is one of those services that will expose your ethernet address, AFAIK. nbtstat. Of course anyone who isn't firewalling 137:139 is an idiot.

Ok, well I was just coming here to ask this exact question.
Since it can't be done, any ideas on a way to maybe I.D. clients? Give each an I.D. number that you can ban or something?

Ehm... <cough cough>... wouldn't the clients be stupid if they identify themselves?

That said, what you can do to identify clients is to either
  • save their hublist then use that to compare when new users connect (downloading their hublist and comparing with the saved ones, if they match to (75-90) percent then kickban the user)
  • save the path and size of, say, five files - check to see if they are present in any new users share (much faster but will give false positives)
  • save a hash of the hublist and compare that (fast but requires download of the hublist and can be defeated by moving as little as one shared file - almost no chance (depending on the hashing algorith) of false positives)
  • save the size of the hublist and using that (very, very fast, will however give false positives and is easy to defeat).
These are just some ideas, feel free to come up with your own. :)
