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.

Using APIPA to configure the IP address

A

The Brother print server supports the Automatic Private IP Addressing (APIPA) protocol. With APIPA, DHCP 
clients automatically configure an IP address and subnet mask when a DHCP server is not available. The 
device chooses it's own IP address in the range 169.254.1.0 through to 169.254.254.255. The subnet mask 
is automatically set to 255.255.0.0 and the gateway address is set to 0.0.0.0. 
By default, the APIPA protocol is enabled. If you want to disable the APIPA protocol, you can disable it using 
control panel of the machine. For more information, see 

APIPA

on page 22. 

If the APIPA protocol is disabled, the default IP address of a Brother print server is 192.0.0.192. However, 
you can easily change this IP address number to match with the IP address details of your network.

Using ARP to configure the IP address

A

If you are unable to use the BRAdmin application and your network does not use a DHCP server, you can 
also use the ARP command. The ARP command is available on Windows

®

 systems that have TCP/IP 

installed as well as UNIX

®

 systems. To use arp enter the following command at the command prompt:

arp -s ipaddress ethernetaddress

Where 

ethernetaddress

 is the Ethernet address (MAC address) of the print server and 

ipaddress

 is the 

IP address of the print server. For example:

„

Windows

®

 systems

Windows

®

 systems require the dash “-” character between each digit of the Ethernet address.

arp -s 192.168.1.2 00-80-77-31-01-07

„

UNIX

®

/Linux systems

Typically, UNIX

®

 and Linux systems require the colon “:” character between each digit of the Ethernet 

address.

arp -s 192.168.1.2 00:80:77:31:01:07

Note

You must be on the same Ethernet segment (that is, there cannot be a router between the print server and 
operating system) to use the arp -s command. 
If there is a router, you may use BOOTP or other methods described in this chapter to enter the IP 
address.If your Administrator has configured the system to deliver IP addresses using BOOTP, DHCP or 
RARP your Brother print server can receive an IP address from any one of these IP address allocation 
systems. In which case, you will not need to use the ARP command. The ARP command only works once. 
For security reasons, once you have successfully configured the IP address of a Brother print server using 
the ARP command, you cannot use the ARP command again to change the address. The print server will 
ignore any attempts to do this. If you wish to change the IP address again, use a web browser, TELNET
