[FUG-BR] RES: quando vem a ultima versão do carp

[Luiz Gustavo]

Eai Marcello....

e se eu precisar monitorar a wan também .....

o grande lance é que pra configurar um carp eu preciso no mínimo 3 ip's, 
2 físicos nas placas e mais 1 logico que é identificado pela classe de 
ip (ele associa o carp à placa que têm a mesma classe de ip).

Com a opção 'carpdev' eu não preciso mais dessa associação, essa opção 
associa a placa diretamente e nem há mais necessidade de eu colocar ip 
físico, basta o ip logico (virtual).

O freevrrpd faz isso, mas ele trabalha a nivel userland e coloca/tira os 
alias nas placas, semelhante ao heartbeat do linux, com a vantagem de 
usar vrrp como protocolo de monitoramento.

Abraços
