Chapter 5.
Configuring Other Computers via DHCP
Network Configuration, covered configuring a computer to function on a TCP/IP
network in any of several different ways. One of these ways was to use a
Dynamic Host Configuration Protocol (DHCP) server. In this configuration, the
computer sends out a broadcast query to locate a DHCP server, which responds by
providing the computer with an IP address and other necessary configuration
information. This configuration is very convenient for the DHCP client, because
it obviates the need to enter the computer's IP address, IP addresses for
gateways, and related information. DHCP doesn't work by magic, though. If
you're running your own network, it requires that you configure a DHCP server computer to answer DHCP client requests. This
chapter covers how to do this.Before configuring a DHCP server, you should
ask yourself whether you want to do this. If so, you need to locate the DHCP
configuration files. The most basic configuration involves having the DHCP
server assign IP addresses that may vary from one client boot to another, but
with some more work you can have DHCP assign the same IP address to specific
computers time after time. The final topic covered in this chapter concerns
integrating a DHCP server with other servers, such as Samba and a Domain Name
System (DNS) server.As with many topics covered in this book,
this chapter cannot cover all the details, but it should get you started, and
may be enough for many configurations. If you need to create an extremely
complex DHCP configuration, you may need to consult a book dedicated to the
topic, such as Droms & Lemons' The DHCP Handbook:
Understanding, Deploying, and Managing Automated Configuration Services
(New Riders Publishing, 1999) or Kercheval's DHCP: A
Guide to Dynamic TCP/IP Network Configuration (Prentice Hall, 1999).
