                 sete passos para configurar uma rede


1o. - verifique se o modulo que habilita o suporte a placa de rede foi carregado.

[root@eliel root]# lsmod

 Module                  Size  Used by
ext2                   71272  0
ide_cd                 41604  0

mbcache                 8580  2 ext2,ext3
reiserfs              236756  2


2o. - Configurar DNS no arquivo /etc/modules.conf

 [root@eliel root]# vi /etc/modules.conf
 

adicione a linha:

 [root@eliel root]# alias eth0 8139too


ativar o módulo da placa 

 [root@eliel root]# modprobe 8139too


3o. - Efetuar a configuracao da rede

 [root@eliel root]# ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up


4o. - Ativando o roteador da rede

certificar-se do acesso a net pelo dispositivo eth0:

 [root@eliel root]# route del default
 [root@eliel root]# route add default eth0

adicionando o gateway da rede:

 [root@eliel root]# route add default gw 192.168.0.2


5o. - Configurando o servidor de DNS da rede

 [root@eliel root]# vi /etc/resolv.conf

adicione estas linhas:

nameserver 200.235.170.162
nameserver 200.235.170.163


6o. - Adicionado outras rotas para diversas rede

route add -net 10.10.1.0 netmask 255.255.255.0 eth1
route add -net 172.100.2.0 netmask 255.255.255.0 eth2
route add -net 192.168.3.0 netmask 255.255.255.0 eth3
route add default eth0



7o. - Execucao durante o boot da maquina

editar o arquivo /etc/init.d/bootmisc.sh (Kurumin, Debian e outros) ou no arquivo /etc/rc.d/rc.local (outras distribuicoes)

 [root@eliel root]# vi /etc/rc.d/rc.local

#!/bin/sh
#
# /etc/rc.d/rc.local: Local system initialization script.
#
# setup commands:

modprobe 8139too
ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up
route del default
route add default eth0
route add default gw 192.168.0.2

ESC:wq
