Caro Ueder,

tinha postado na lista do debian sobre amarrar ip ao mac e você respondeu que fez isso facilmente com a opção /etc/ethers.
Como funciona essa opção? É algo atrelado a arp?

Preciso liberar acesso numa rede somente a IPs amarrados ao MAC.
Nao é acesso a internet.. é à rede mesmo.

Obrigado.
