You should not need to change the default configuration of these daemons.
If the server where the Preboot Services components are installed is also a DHCP server, see

29.3.2 Deploying Preboot Services In a Network Environment

To implement the network deployment strategies outlined in this section, you must have a solid
understanding of the TCP/IP network protocol and specific knowledge of TCP/IP routing and the
DHCP discovery process.
Deploying Preboot Services (with PXE) in a single network segment is a relatively simple process.
However, Preboot Services deployment in a multi-segment network is far more complex and might
require configuration of both the Preboot Services daemons and the network switches and routers
that lie between the server and the PXE devices.
Configuring the routers or switches to correctly forward Preboot Services network traffic requires a
solid understanding of the DHCP protocol, DHCP relay agents, and IP forwarding. The actual
configuration of the switch or router must be performed by a person with detailed knowledge of the
hardware.
We strongly recommend that you initially set up Preboot Services in a single segment to ensure that
the servers are configured correctly and are operational.
This section includes the following information:
"Server Configuration" on page 366
"Network Configuration" on page 368

Server Configuration
There are three important points about configuring servers for Preboot Services:
DHCP server: The Preboot Services environment requires a standard DHCP server. It is up to
you to install your standard DHCP server.
Preboot Services daemons: The four Preboot Services daemons (novell-pbserv, novell-tftp,
novell-proxydhcp, and novell-zmgprebootpolicy) are all installed on the imaging server when
you install ZENworks Linux Management. These daemons must run together on the same
server.
