# Te situas en el servidor en cuestion como usuario: <tt>root</tt>
# entras en el directorio: <tt>cd /etc/sysconfig/network-scripts</tt>
# y editas los ficheros: <tt>ifcfg-eth0, ifcfg-eth1</tt>, etc.

! Formato para editar esos ficheros y asignar una IP
<tt>DEVICE=eth0</tt>
<tt>BOOTPROTO=none</tt>
<tt>BROADCAST=16.0.62.255</tt>
<tt>HWADDR=00:15:C5:88:E8:97</tt>
<tt>IPADDR=16.0.62.10</tt>
<tt>NETMASK=255.255.255.0</tt>
<tt>NETWORK=16.0.62.0</tt>
<tt>ONBOOT=yes</tt>
<tt>TYPE=Ethernet</tt>
<tt>USERCTL=no</tt>
<tt>PEERDNS=yes</tt>
<tt>GATEWAY=16.0.62.1</tt>
<tt>IPV6INIT=no</tt>

! Formato para editar esos ficheros y dejar IP SIN asignar
<tt>DEVICE=eth1</tt>
<tt>BOOTPROTO=dhcp</tt>
<tt>HWADDR=00:04:23:C5:D8:29</tt>
<tt>ONBOOT=no</tt>
<tt>TYPE=Ethernet</tt>
<tt>DHCP_HOSTNAME=bd-ventilacion</tt>

NOTA1: Tras configurar las interfaces; el comando <tt>ifconfig -a</tt> debe dar un resultado con este aspecto:
