Using RARP to Configure the IP Address 

The Brother Print/Fax 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   BRN_310107

Where the first entry is the Ethernet address of the Print/Fax server 
and the second entry is the name of the Print/Fax 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/Fax server will get the IP address from the rarp 
daemon when the printer is powered on. 

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
