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 it is powered on.

BOOTP mode

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” below is “BRW” for a wireless network.)

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.
