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.

Red Hat 9.0: Dynamic IP Address Setting in ifconfig-eth0  

DEVICE=eth0
ONBOOT=yes

BOOTPROTO=dhcp

USERCTL=no
PEERDNS=yes
TYPE=Ethernet

• 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.
