Note
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:
BRN008077310107 1 00:80:77:31:01:07 192.168.1.2
and:
BRN008077310107:ht=ethernet:ha=008077310107:\
ip=192.168.1.2:
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.
Using RARP to configure the IP address
A
The Brother print server’s IP address can be configured using the Reverse ARP (RARP) facility on your host
computer. This is done by editing the
/etc/ethers
file (if this file does not exist, you can create it) with an
entry similar to the following:
00:80:77:31:01:07 BRN008077310107
Where the first entry is the Ethernet address of the print server and the second entry is the name of the print
server (the name must be the same as the one you put in the
/etc/hosts
file).
If the rarp daemon is not already running, start it (depending on the system the command can be
rarpd
,
rarpd -a
,
in.rarpd -a
or something else; type
man rarpd
or refer to your system documentation for
additional information). To verify that the rarp daemon is running on a Berkeley UNIX
®
-based system, type
the following command:
ps -ax | grep -v grep | grep rarpd
For AT&T UNIX
®
-based systems, type:
ps -ef | grep -v grep | grep rarpd
The Brother print server will get the IP address from the rarp daemon when the printer is powered on.
