• Edit the /etc/sysconfig/network as follows: Static: NETWORKING=yes HOSTNAME="pxe1.pxe.net" Dynamic: NETWORKING=yes HOSTNAME="pxe1.pxe.net" DHCP_HOSTNAME="pxe1.pxe.net" 5. Set up the DHCP service. • A sample /etc/dhcpd.conf configuration file is located at /usr/share/doc/dhcp3.0pl1/dhcpd.conf.sample. Copy this sample to /etc/dhcpd.conf. • If more than one network card resides in the DHCP server, HP recommends specifying which interfaces the DHCP server will use. Edit /etc/sysconfig/dhcpd by adding the appropriate interface to the DHCPDARGS= line. The entry in /etc/sysconfig/dhcpd should appear as follows: DHCPDARGS=eth0 • Run the following command to ensure that the DHCP service will be started at each boot: chkconfig --level 345 dhcpd on 6. Configure xinetd and TFTP services. At this point, the TFTP server should be installed. • Enable the TFTP server by using the chkconfig command line utility as follows: chkconfig tftp on • Ensure that xinetd is enabled, as TFTP is started and stopped by xinetd, using the following command: chkconfig --level 345 xinetd on • Notify xinetd that the TFTP service has been enabled. Use the following command: service xinetd restart 7. Add the next-server and filename options into the /etc/dhcpd.conf files. To accomplish this task, add the following to the global section: if substring (option vendor-class-identifier, 0, 9) = "PXEClient" { filename "pxelinux.0"; next-server 172.48.0.1; } 8. Optional step: Assign fixed addresses to each of the clients. The benefit is having the ability to access the clients with the same IP address. The alternative s to use name resolution such as DNS: host 00080246e75d { hardware ethernet 00:08:02:46:e7:5d; fixed-address 172.48.1.253; } 5

Edit the /etc/sysconfig/network as follows:
Static:
NETWORKING=yes
HOSTNAME="pxe1.pxe.net"
Dynamic:
NETWORKING=yes
HOSTNAME="pxe1.pxe.net"
DHCP_HOSTNAME="pxe1.pxe.net"
5.
Set up the DHCP service.
•
A sample /etc/dhcpd.conf configuration file is located at /usr/share/doc/dhcp-
3.0pl1/dhcpd.conf.sample. Copy this sample to /etc/dhcpd.conf.
•
If more than one network card resides in the DHCP server, HP recommends specifying which
interfaces the DHCP server will use. Edit /etc/sysconfig/dhcpd by adding the appropriate
interface to the DHCPDARGS= line. The entry in /etc/sysconfig/dhcpd should appear as
follows:
DHCPDARGS=eth0
•
Run the following command to ensure that the DHCP service will be started at each boot:
chkconfig --level 345 dhcpd on
6.
Configure xinetd and TFTP services. At this point, the TFTP server should be installed.
•
Enable the TFTP server by using the chkconfig command line utility as follows:
chkconfig tftp on
•
Ensure that xinetd is enabled, as TFTP is started and stopped by xinetd, using the following
command:
chkconfig --level 345 xinetd on
•
Notify xinetd that the TFTP service has been enabled. Use the following command:
service xinetd restart
7.
Add the next-server and filename options into the /etc/dhcpd.conf files. To accomplish this task,
add the following to the global section:
if substring (option vendor-class-identifier, 0, 9) = "PXEClient"
{
filename "pxelinux.0";
next-server 172.48.0.1;
}
8.
Optional step:
Assign fixed addresses to each of the clients. The benefit is having the ability to
access the clients with the same IP address. The alternative s to use name resolution such as DNS:
host 00080246e75d {
hardware ethernet 00:08:02:46:e7:5d;
fixed-address 172.48.1.253;
}
