O servidor DHCP não inicia

Question

Eu instalei o dhcp3-server no servidor ubuntu 11.04

apt-get install dhcp3-server

No entanto, uma mensagem de erro durante a instalação:

quando eu quiser acessar o arquivo /etc/dhcp3/dhcpd.conf não consigo encontrá-lo, mas o pacote dhcp-server está instalado.

Answer 1

Tente editar /etc/dhcp/dhcpd.conf . Ele deve ser instalado junto com o pacote isc-dhcp-server e o pacote dhcp3-server que depende dele.

$ dpkg -S dhcpd.conf
isc-dhcp-server: /usr/share/doc/isc-dhcp-server/examples/dhcpd.conf
isc-dhcp-server: /etc/dhcp/dhcpd.conf
isc-dhcp-server: /usr/share/man/man5/dhcpd.conf.5.gz

    

Answer 2

Para executar um servidor DHCP, você precisa editar o arquivo /etc/default/dhcp primeiro e definir a lista de interfaces de rede ativas. Nessas interfaces, o DHCP atenderá as solicitações. Então você tem que configurar o servidor editando /etc/dhcp/dhcpd.conf e adicionando a entrada "subnet" apropriada.
