Assuming that you have only one network card on the computer, locate the
ifconfig-
eth0
configuration file (where
eth0
is the name of the Ethernet card). Open the
configuration file with any plain text editor.
If you have a dynamic IP address, enter
dhcp
in the
BOOTPROTO=
field.
The
following figure shows an example.
Figure 66
Red Hat 9.0: Dynamic IP Address Setting in ifconfig-eth0
If you have a static IP address, enter
static
in the
BOOTPROTO=
field. Type
IPADDR
= followed by the IP address (in dotted decimal notation) and type
NETMASK
= followed by the subnet mask. The following example shows an example
where the static IP address is 192.168.1.10 and the subnet mask is 255.255.255.0.

If you know your DNS server IP address(es), enter the DNS server information in the
resolv.conf
file in the
/etc
directory.
The following figure shows an example where
two DNS server IP addresses are specified.

After you edit and save the configuration files, you must restart the network card. Enter
./network restart
in the
/etc/rc.d/init.d
directory.
The following figure
shows an example.
