Appendix B

Protocols

B

TCP/IP protocols and functions

Protocols are the standardized sets of rules for transmitting data on a network. Protocols allow users to gain access to network connected resources.

The print server used on the Brother printer supports the TCP/IP (Transmission Control Protocol/Internet

Protocol) protocol.

TCP/IP is the most popular set of protocols used for communication such as Internet and E-mail. This protocol can be used in almost all operating systems such as Windows

®

, Windows Server

®

, Mac OS X and Linux

®

.

The following TCP/IP protocols are available on the Brother printer.

B

Note

• You can configure the protocol settings by using the HTTP interface (web browser). (See Configuring the

printer settings using Web Based Management (web browser) uu page 12.)

• To find what protocols your Brother printer supports, see Supported protocols and security features uu page 17.

DHCP/BOOTP/RARP

By using the DHCP/BOOTP/RARP protocols, the IP address can be automatically configured.

B

Note

To use the DHCP/BOOTP/RARP protocols, please contact your network administrator.

APIPA

If you do not assign an IP address manually (using the BRAdmin software) or automatically (using a

DHCP/BOOTP/RARP server), the Automatic Private IP Addressing (APIPA) protocol will automatically assign an IP address from the range 169.254.1.0 to 169.254.254.255.

B

B

ARP

Address Resolution Protocol performs mapping of an IP address to a MAC address in a TCP/IP network.

B

DNS client

The Brother print server supports the Domain Name System (DNS) client function. This function allows the print server to communicate with other devices by using its DNS name.

B

NetBIOS name resolution

Network Basic Input/Output System name resolution enables you to obtain the IP address of the other device using its NetBIOS name during the network connection.

B

WINS

Windows ® Internet Name Service is a service providing information for NetBIOS name resolution, by consolidating an IP address and a NetBIOS name that is on the local network.

B

20

Appendix B

LPR/LPD

Commonly used printing protocols on a TCP/IP network.

Custom Raw Port (Default is Port 9100)

Another commonly used printing protocol on a TCP/IP network. It enables interactive data transmission.

mDNS mDNS allows the Brother print server to automatically configure itself to work in a Mac OS X Simple Network

Configured system.

B

SNMP

The Simple Network Management Protocol (SNMP) is used to manage network devices including computers, routers and Brother network ready printers. The Brother print server supports SNMPv1 and SNMPv2.

B

B

B

LLMNR

The Link-Local Multicast Name Resolution protocol (LLMNR) resolves the names of neighboring computers if the network does not have a Domain Name System (DNS) server. The LLMNR Responder function works in both the IPv4 or IPv6 environment when using a computer that has the LLMNR Sender function such as

Windows Vista

®

and Windows

®

7.

B

B

21

Appendix B

Configuring your printer for a network

B

IP addresses, subnet masks and gateways

To use the printer in a networked TCP/IP environment, you need to configure its IP address and subnet mask.

The IP address you assign to the print server must be on the same logical network as your host computers.

If it is not, you must properly configure the subnet mask and the gateway address.

B

IP address

An IP address is a series of numbers that identifies each device connected to a network. An IP address consists of four numbers separated by dots. Each number is between 0 and 255.

 Example: In a small network, you would normally change the final number.

• 192.168.1.1

• 192.168.1.2

• 192.168.1.3

How the IP address is assigned to your print server:

If you have a DHCP/BOOTP/RARP server on your network the print server will automatically obtain its IP address from that server.

B

Note

On smaller networks, the DHCP server may also be the Router.

For more information on DHCP, BOOTP and RARP, see:

Using DHCP to configure the IP address uu page 26.

Using BOOTP to configure the IP address uu page 27.

Using RARP to configure the IP address uu page 26.

If you do not have a DHCP/BOOTP/RARP server, the Automatic Private IP Addressing (APIPA) protocol will automatically assign an IP address from the range 169.254.1.0 to 169.254.254.255. For more information on

APIPA, see Using APIPA to configure the IP address uu page 27.

B

B

22

Appendix B

Subnet mask

Subnet masks restrict network communication.

 Example: Computer 1 can talk to Computer 2

• Computer 1

IP Address: 192.168. 1. 2

Subnet Mask: 255.255.255.0

• Computer 2

IP Address: 192.168. 1. 3

Subnet Mask: 255.255.255.0

Where the 0 is in the Subnet mask, there is no limit to communication at this part of the address. What this means in the above example is, we can communicate with any device that has an IP address that begins with

192.168.1.x. (where x. are numbers between 0 and 255).

B

Gateway (and router)

A gateway is a network point that acts as an entrance to another network and sends data transmitted via the network to an exact destination. The router knows where to direct data that arrives at the gateway. If a destination is located on an external network, the router transmits data to the external network. If your network communicates with other networks, you may need to configure the Gateway IP address. If you do not know the Gateway IP address then contact your Network Administrator.

B

23

Appendix B

Wireless network terms and concepts

Specifying your network

B

B

SSID (Service Set Identifier) and channels

You need to configure the SSID and a channel to specify the wireless network you want to connect to.

 SSID

Each wireless network has its own unique network name which is technically referred to as an SSID or

ESSID (Extended Service Set Identifier). The SSID is a 32-byte or less value and is assigned to the access point. The wireless network devices you want to associate to the wireless network should match the access point. The access point and wireless network devices regularly send wireless packets (referred to as a beacon) which has the SSID information. When your wireless network device receives a beacon, you can identify the wireless network that is close enough for the radio waves to reach your device.

 Channels

Wireless networks use channels. Each wireless channel is on a different frequency. There are up to 14 different channels that can be used when using a wireless network. However, in many countries the number of channels available are restricted.

Security terms

B

Authentication and encryption

Most wireless networks use some kind of security settings. These security settings define the authentication

(how the device identifies itself to the network) and encryption (how the data is encrypted as it is sent on the network). If you do not correctly specify these options when you are configuring your Brother wireless

printer, it will not be able to connect to the wireless network. Therefore care must be taken when configuring these options.

B

Authentication and Encryption methods for a personal wireless network

A personal wireless network is a small network, for example using your printer in a wireless network at home, without IEEE 802.1x support.

Appendix B

Authentication methods

 Open system

Wireless devices are allowed to access the network without any authentication.

 Shared key

A secret pre-determined key is shared by all devices that will access the wireless network.

The Brother wireless printer uses a WEP key as the pre-determined key.

 WPA-PSK/WPA2-PSK

Enables a Wi-Fi Protected Access Pre-shared key (WPA-PSK/WPA2-PSK), which enables the Brother wireless printer to associate with access points using TKIP for WPA-PSK, or AES for WPA-PSK and

WPA2-PSK (WPA-Personal).

B

Encryption methods

 None

No encryption method is used.

 WEP

When using WEP (Wired Equivalent Privacy), the data is transmitted and received with a secure key.

 TKIP

TKIP (Temporal Key Integrity Protocol) provides per-packet key mixing, a message integrity check and rekeying mechanism.

 AES

B

AES (Advanced Encryption Standard) is the Wi-Fi ® authorized strong encryption standard.

B

Network key

 Open system/Shared key with WEP

This key is a 64-bit or 128-bit value that must be entered in an ASCII or hexadecimal format.

• 64 (40) bit ASCII:

Uses 5 text characters. e.g. “WSLAN” (this is case sensitive)

• 64 (40) bit hexadecimal:

Uses 10 digits of hexadecimal data. e.g. “71f2234aba”

• 128 (104) bit ASCII:

Uses 13 text characters. e.g. “Wirelesscomms” (this is case sensitive)

• 128 (104) bit hexadecimal:

Uses 26 digits of hexadecimal data. e.g. “71f2234ab56cd709e5412aa2ba”

 WPA-PSK/WPA2-PSK and TKIP or AES

Uses a Pre-Shared Key (PSK) that is 8 or more characters in length, up to a maximum of 63 characters.

Appendix B

Other ways to set the IP address (for advanced users and administrators)

B

Using DHCP to configure the IP address

The Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address allocation. If you have a DHCP server on your network, the print server will automatically obtain its IP address from the DHCP server and register its name with any RFC 1001 and 1002-compliant dynamic name services.

Note

If you do not want your print server configured via DHCP, BOOTP or RARP, you must set the Boot Method to static so that the print server has a static IP address. This will prevent the print server from trying to obtain an IP address from any of these systems. To change the Boot Method, use the BRAdmin applications or Web Based Management (web browser).

B

Using RARP to configure the IP address

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 (or BRW008077310107 for a wireless network)

Where the first entry is the MAC Address (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).

The Brother print server will get the IP address from the RARP daemon when the printer is powered on.

B

Appendix B

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

Depending on the system, this entry might be called “bootps” instead of “bootp”.

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), MAC Address (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. Some examples of typical

/etc/bootptab entries include: (“BRN” below is “BRW” for a wireless network.)

BRN310107 1 00:80:77:31:01:07 192.168.1.2

and:

BRN310107: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.

B

B

Using APIPA to configure the IP address

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

BRAdmin Light or Web Based Management (web browser).

B

27

Appendix B

Using ARP to configure the IP address

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. To use ARP enter the following command at the command prompt: arp -s ipaddress ethernetaddress ping ipaddress

Where ethernetaddress is the MAC Address (Ethernet 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 MAC Address (Ethernet

Address).

arp -s 192.168.1.2 00-80-77-31-01-07 ping 192.168.1.2

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 Based Management

(web browser), TELNET (using the SET IP ADDRESS command) or factory reset the print server (which will then allow you to use the ARP command again).
