Configuring for a DHCP Server
Setting Up a DHCP Server
If you also specify a boot-file (bf) of /opt/ignite/boot/boot_lif in
the bootptab entries, then you do not need any additional entries in
/etc/opt/ignite/inst_boottab. In this case, you would then boot
the clients using boot lan instead of boot lan install. Only clients
known in /etc/bootptab would be able to boot if you do not use
instl_boottab.
A minimal example /etc/bootptab entry would be like the entry below
(with your own hostname, IP address, hardware address, and subnet
mask). Other networking information may also be specified here, or can
be specified via instl_adm. The IP address of the IUX server must be
specified with the instl_adm -t option.

protocol, and in fact the HP-UX DHCP server daemon and the BOOTP
Design
daemon are the same (bootpd(1M)). This daemon reads two configuration
files: /etc/bootptab and /etc/dhcptab.
The mapping of systems to IP addresses and lease time information is
kept in the DHCP database file /etc/dhcpdb. Some amount of
management of this database is provided by the dhcptools(1M)
command.
On the client side, a command called /usr/lbin/dhcpclient is used
to contact the server to get an IP address lease. This command has the
ability to broadcast out onto the network prior to the network interface
being enabled.
The dhcpclient also serves as a daemon process that sleeps until the
time that it needs to renew the IP address lease, at which time it will
re-contact the server where it got the original lease in order to extend it.
The dhcpclient command is not intended to be run by users directly,
and is called by other tools during system bootup and installation.
For More Information Refer to the auto_parms(1M) man page and the dhcpdb2conf(1M) man
page for more information regarding the networking parameters which
DHCP can supply.
