Appendix B Setting up Your Computer’s IP Address 142
1 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 90 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.

2 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.

3 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.
