<H2>Configuring DHCP Clients</H2>
<P>
Clients contact the DHCP server at boot time to request an
Internet address and configuration information.  The information
that the client receives is specified in files in the 
<VAR>/var/dhcp/config</VAR> directory.  This directory
contains a separate configuration file for each network or subnet
in an organization. When you configure the DHCP clients on a network,
you specify the configuration information that is contained in the
DHCP file for a particular network.
</P>
(Default value: none)
<P>
This page contains a long list of parameters that a DHCP Server can 
send to a client system.  By default, most parameters are hidden. Click
the <I>Go to Advanced Options</I>button to display all
available DHCP parameters.
</P>
(Default value: none)
<P>
If you leave a parameter blank or as it was, DHCP uses the
default values. After you make changes, click the 
<I>Ok</I> button to put the changes into effect.
</P>

<P>
<STRONG>Enable DHCP service for this network:</STRONG> This selection 
controls whether this DHCP server answers requests for this network.
Select <VAR>Yes</VAR> if this server is to answer DHCP requests for this
network; select <VAR>No</VAR> if this server is to ignore DHCP requests 
from this network.
</P>
(Default value: none)
<P>
<STRONG>Allow clients to choose their own hostname:</STRONG> This selection
controls an SGI extension to the DHCP protocol, which allows SGI clients
to request an alternative hostname from the name that is offered. Select
<VAR>Yes</VAR> to allow clients to request an alternative hostname; select 
<VAR>No</VAR> to prevent clients from requesting an alternative hostname. 
When yes is set, a warning is issued if a client requests a name that is
already in use.
</P>
(Default value: yes)
<P>
<STRONG>Prefix for automatic hostname assignments:</STRONG> DHCP generates
host names by appending a number to this word. Enter a single word for this 
prefix. Do not use punctuation in your entry.
</P>
(Default value: irix)
<P>
<STRONG>Generate new IP addresses from this range:</STRONG> This parameter
allows you to limit client addresses to a subset of the addresses in the entire 
network. This partitioning is particularly useful if the network is shared by 
multiple administrative bodies.  Enter two numbers between 1 and 254 and 
separate your entries with a dash (for example, 50-100 is a valid entry).
</P>
(Default value: none)
<P>
<STRONG>Subnet mask for this network:</STRONG> The Internet address for
a system contains a network number in the most significant bits and
a host number in the least significant bits. A subnet mask overlays the
Internet address to designate the host portion of the address. The mask
contains all ones in the bits associated with the network number and all
zeros in the bits associated with the host number. Enter a network mask 
in dotted decimal notation (such as 255.255.0.0) or hexadecimal notation
(such as 0xffff0000).
</P>
(Default value: none)
<P>
<STRONG>NIS domain name for this network:</STRONG> If this network is
served by an NIS name server, this is the domain name that clients 
specify when looking up a name. This is typically key words concatenated 
with a period (such as engr.sgi.com), and is frequently the same as the DNS
domain name. Enter a one-word domain name; do not use spaces in your entry.
</P>
(Default value: none)
<P>
<I>Advanced options are are described in the dhcp_bootp(1M) reference page.</I>
