Dynamic Host Configuration Protocol (DHCP)
Configuring DHCP
BOOTP client part of a DHCP group that has been defined. bootpd is the
internet boot protocol server daemon that implements DHCP, BOOTP,
and DHCP/BOOTP relay agents.
DHCP is backwards compatible with BOOTP, so no changes are required
of existing users of BOOTP.
Configuring DHCP to be Used with OL*
To use DHCP with OL*, you will need to kill the bootp daemon after you
complete the replacement for OL*.
NOTE The bootp daemon should be killed manually and later started manually
after the OL* operations.
Configuring DHCP to Deny Address Allocation to
Specific Clients
You can configure the HP-UX DHCP server to refuse to allocate IP
addresses to certain clients. In the /etc/dhcpdeny configuration file, list
the hardware addresses of the clients you want to deny IP address
allocation.
Below is an example of how the hardware addresses should be listed in
the /etc/dhcpdeny file:
0x000aabbbcccd
0x0060B02088B4
6a123400ffed
By default, DHCP assumes all the addresses as hexadecimal addresses.
Addresses that do not have “0x” as the prefix will be treated as
hexadecimal addresses.
