5.4.6 Configuring
If you are not assigning a static IP address to be stored in the HW400c/2 non-volatile
me ory, it is necessary to configure a bootp server. Bootp (a precursor to DHCP)
will assign an IP address to a device with a specific MAC address based on what is
up table called bootptab. At power up, the HW400c/2 will
broadcast a BOOTP_REQUEST over the network. If a server is actively running
ootpd, that server will look through its bootptab for a matching MAC address. If a
_REPLY to the
W400c/2’s MAC address and assign the IP address found in the bootptab file.

a bo p nning on your system, enter:

root 20587 20484 0 15:27 pts/8 00:00:00 grep bootpd
This command will stop and then start all of the Internet services on your Linux system. You may not
want to do this if your system is running Internet services on which other systems depend, as it will
cause a slight interruption in those services.
