the colons between each byte. The ip part of the entry
is where the IP address is specified. There are several
other parameters that can be specified in a bootptab
entry. However, the three parameters shown here are
the only ones required for Network Print Server instal-
lation.
The following sequence of events occurs during the
power up of the Network Print Server using BOOTP.
1. A Network Print Server powers up but does not
know its IP address. (It does know its network
hardware address.)
2. The Network Print Server sends out a BOOTP
request packet with its network hardware address.
For this example, the network hardware address is
00:40:68:17:50:A4.
3. The bootpd daemon running on a BOOTP server
(which in this example is a UNIX workstation) sees
the BOOTP request along with the network hard-
ware address. It looks up the network hardware
address in the "/etc/bootptab" file. The bootpd dae-
mon finds the associated IP address of the device
in the bootptab file.
4. The bootpd daemon transmits a response to the
Network Print Server with the IP address
192.168.42.55. The Network Print Server uses this
IP address for all subsequent transmissions.
For these steps to work properly, at least one BOOTP
daemon (bootpd) must be running on the BOOTP
server. To test whether a BOOTP daemon is running
on the BOOTP server, use the ps command with the
show all process option within fifteen minutes of an
TCP/IP
