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
✒ 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:
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 server will load its IP address from the BOOTP server when the printer
is powered on.
