[CentOS-pt-br] Up link automático

Boa tarde Fábio,


O script ifup apenas levanta a interface, pelo menos no centos! Quando a
interface está configurada para DHCP, o é mandatório para a interface
cliente, perder o IP é o tempo que você configura no servidor DHCP para
fixar o ip no cliente...


Se esse tempo esgotar e você reconectar ou energizar o cabo , ele não irá
pegar o ip mesmo não! Pois o ifup apenas acorda a interface... E de nada
adiantará...

Mas o se o cabo for colocado novamente ou energizado sem ter ultrapassado o
limite configurado no SERVER DHCP ele então volta com o IP que ja estava
configurado na interface... pois a interface cliente ainda manterm a ordem
de manter o ip dentro do tempo especificado...

Testar essa condição talvez seja válida...
