CHAPTER 1 TCP/IP CONFIGURATION
1-8
Using BOOTP to Configure the IP Address
BOOTP is an alternative to rarp that has the advantage of allowing configuration
of the subnet mask and gateway. 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
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 / Fax
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:
BRN_310107 1 00:80:77:31:01:07 192.189.207.3
and:
BRN_310107: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 / Fax server will load its IP address from the BOOTP
server when the FAX/MFC is powered on.
