RARP mode

Brother print server 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   BRN_310107

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 it is powered on. 

BOOTP mode

BOOTP is an alternative to RARP. However, unlike RARP, it is able to configure 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:
