Olá pessoal, preciso da ajuda de vcs...utilizo em meu servidor o ubuntu 7.04 e atribui mais 1 ip na minha placa de rede interna (etho) para criar uma subrede, onde minha rede principal é 192.168.1.0 e a subrede 192.168.2.0.
Mais o problema, é q o meu dhcp não está distribuindo os ips dinamicamente, mesmo eu adicionando o ip+mac, para minha subrede 192.168.2.0.
Gostaria da ajuda de vcs...
Obrigado.

basta fazer ifconfig eth0 192.168.1.1 e ifconfig eth0:0 192.168.2.1

Cara nos mostre como esta o seu /etc/dhcp.conf.
Deve estar parecido com o abaixo:
