Eu deveria ter 3 sites em um apache2 (Ubuntu atualizado).
Cada site tem seu próprio arquivo em "sites habilitados". Cada um tem seu próprio IP.
O Apache2 parece estar rodando bem: /var/log/apache2/error.log apenas diz: [Sex 08 Nov 12:30:12 2013] [notice] Apache / 2.2.22 (Ubuntu) PHP / 5.4.6-1ubuntu1.4 configurado - retomando as operações normais
Os arquivos DNS parecem OK. Mas quando eu aponto um navegador para o segundo e terceiro site (para seus nomes de domínio ou para seus endereços IP), ele simplesmente trava até o tempo limite.
O que devo verificar em seguida, por favor?

Eu não entendo muito disso, mas posso ver os IPs: 92.243.20.169, 92.243.21.141 e 92.243.4.114, que são como deveriam ser. Não sei se é normal que o Bcast e o Mask sejam diferentes. Os relatórios sobre os pacotes também parecem corretos para mim.

Por "os arquivos DNS parecem OK", quero dizer que eu não os modifiquei e nenhum programa os modificou. Eles costumavam funcionar antes, então eu acho que eles estão bem. Gostaria que eu publicasse uma cópia deles?
Se você tiver vários IPs, precisará de várias interfaces ativadas. Você pode pingar os IPs? pode nem ser um problema do Apache. Digite "ip addr" ou "ifconfig" e veja se você os vê listados.
Se tudo estiver correto, verifique se os hosts virtuais estão configurados para ouvir em cada IP, respectivamente.
