I would like to know what are the good way to identify users on a large lan party when you manage network ?
I had the idea to make the users register them self at a desk, they give us Firstname, Lastname, MAC address, then we give them an IP linked to this mac address (permanent lease on the DHCP server), but how could I prevent them to change the IP while disabling the DHCP mode ?
Is there a way to force them to use the DHCP assigned IP ? Is 802.1x a good solution for this ? Maybe too heavy and complicated to setup (I never used it, but I think there is something to do on the computer to connect on the network)
The idea would be to be able to identify the user with it's IP address on the Firewall log to identify hacking attempts or any suspicious activity.
What are your experiences about this ? What do you recommend ?
