BOOTP mode

BOOTP is an alternative to RARP that has the advantage of allowing configuration of the subnet mask and
gateway. For more information on BOOTP, see Using BOOTP to configure the IP address on page 80. In
order to use BOOTP to configure the IP address make sure that BOOTP is installed and running on your host
computer (it should appear in the /etc/services file on your host as a real service; type man bootpd or refer to
your system documentation for information). BOOTP is usually started up via the /etc/inetd.conf file, so you
may need to enable it by removing the “#” in front of the bootp entry in that file. For example, a typical bootp
entry in the /etc/inetd.conf file would be:
#bootp dgram udp wait /usr/etc/bootpd bootpd -i
Note
Depending on the system, this entry might be called “bootps” instead of “bootp”.
In order to enable BOOTP, simply use an editor to delete the “#” (if there is no “#”, then BOOTP is already
enabled). Then edit the BOOTP configuration file (usually /etc/bootptab) and enter the name, network type
(1 for Ethernet), Ethernet address and the IP address, subnet mask and gateway of the print server.
Unfortunately, the exact format for doing this is not standardized, so you will need to refer to your system
documentation to determine how to enter this information (many UNIX
®
systems also have template
examples in the bootptab file that you can use for reference). Some examples of typical /etc/bootptab entries
include:
BRN310107 1 00:80:77:31:01:07 192.189.207.3
and:
BRN310107:ht=ethernet:ha=008077310107:\
ip=192.189.207.3:
Certain BOOTP host software implementations will not respond to BOOTP requests if you have not included
a download filename in the configuration file; if this is the case, simply create a null file on the host and specify
the name of this file and its path in the configuration file.
As with RARP, the print server will load its IP address from the BOOTP server when the printer is powered on.
DHCP mode

Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address
allocation. If you have a DHCP server in your network (typically a UNIX
®
, Windows
®
2000/XP, Windows
Vista
®
network) the print server will automatically obtain its IP address from a DHCP server and register its
name with any RFC 1001 and 1002 compliant dynamic name services.
