 129 <H2 CLASS="title"><A NAME="ADDRESS">Getting the IP Address</A></H2>
 130
 131 <P>When you first install a network printer or print server on
 132 your LAN, you need to set the Internet Protocol ("IP") address.
 133 On most higher-end "workgroup" printers, you can set the address
 134 through the printer control panel. However, in most cases you
 135 will want to assign the addresses remotely from your workstation.
 136 This makes administration a bit easier and avoids assigning
 137 duplicate addresses accidentally.</P>
 138
 139 <P>To setup your printer or print server for remote address
 140 assignment, you'll need the Ethernet Media Access Control ("MAC")
 141 address, also sometimes called a node address, and the IP address
 142 you want to use for the device. The Ethernet MAC address can
 143 often be found on the printer test page or bottom of the print
 144 server.</P>
 145
 146 <H3>Configuring the IP Address Using ARP</H3>
 147
 148 <P>The easiest way to set the IP address of a network device is
 149 to use the <CODE>arp(8)</CODE> command.  The <CODE>arp</CODE>
 150 sends an Address Resolution Protocol ("ARP") packet to the
 151 specified Ethernet MAC address, setting the network device's IP
 152 address:</P>
 153
 154 <PRE CLASS="command">
 155 <KBD>arp -s ip-address ethernet-address</KBD>
 156 <KBD>arp -s host.domain.com 08:00:69:00:12:34</KBD>
 157 <KBD>arp -s 192.0.2.2 08:00:69:00:12:34</KBD>
 158 </PRE>
 159
 160 <H3>Configuring the IP Address Using RARP</H3>
 161
 162 <P>The most flexible way to remotely assign IP addresses under
 163 UNIX is through the Reverse Address Resolution Protocol ("RARP").
 164 RARP allows a network device to request an IP address using its
 165 Ethernet MAC address, and one or more RARP servers on the network
 166 will respond with an ARP packet with the IP address the device
 167 can use.</P>
 168
 169 <P>RARP should be used when you have to manage many printers or
 170 print servers, or when you have a network device that does not
 171 remember its IP address after a power cycle. If you just have a
 172 single printer or print server, the <CODE>arp</CODE> command is
 173 the way to go.</P>
 174
 175 <P>Some UNIX operating systems use a program called
 176 <CODE>rarpd(8)</CODE> to manage RARP. Others, like Linux, support
 177 this protocol in the kernel. For systems that provide the
 178 <CODE>rarpd</CODE> program you will need to start it before RARP
 179 lookups will work:</P>
 180
 181 <PRE CLASS="command">
 182 <KBD>rarpd</KBD>
 183 </PRE>
 184
 185 <P>Under IRIX you can enable this functionality by default
 186 using:</P>
 187
 188 <PRE CLASS="command">
 189 <KBD>chkconfig rarpd on</KBD>
 190 </PRE>
 191
 192 <P>Both the <CODE>rarpd</CODE> program and kernel RARP support
 193 read a list of Ethernet and IP addresses from the file
 194 <VAR>/etc/ethers</VAR>. Each line contains the Ethernet address
 195 (colon delimited) followed by an IP address or hostname like:</P>
 196
 197 <PRE CLASS="command">
 198 08:00:69:00:12:34 myprinter.mydomain.com
 199 08:00:69:00:12:34 192.0.2.2
 200 </PRE>
 201
 202 <P>Add a line to this file and cycle the power on the printer or
 203 print server to set its address.</P>
 204
 205 <H3>Configuring the IP Address Using BOOTP</H3>
 206
 207 <P>The BOOTP protocol is used when you need to provide additional
 208 information such as the location of a configuration file to the
 209 network interface. Using the standard <CODE>bootpd(8)</CODE>
 210 program supplied with UNIX you simply need to add a line to the
 211 <VAR>/etc/bootptab</VAR> file; for IRIX:</P>
 212
 213 <PRE CLASS="command">
 214 myprinter 08:00:69:00:12:34 192.0.2.2 <VAR>myprinter.boot</VAR>
 215 </PRE>
 216
 217 <P>Newer versions of <CODE>bootpd</CODE> use a different
 218 format:</P>
 219
 220 <PRE CLASS="command">
 221 myprinter:ha=080069001234:ip=192.0.2.2:<VAR>t144=myprinter.boot</VAR>
 222 </PRE>
 223
 224 <P>The <VAR>myprinter.boot</VAR> file resides in the
 225 <VAR>/usr/local/boot</VAR> directory by default. If you do not
 226 need to provide a boot file you may leave the last part of the
 227 line blank.</P>
 228
 229 <BLOCKQUOTE><B>Note:</B>
 230
 231 <P>Some versions of UNIX do not enable the BOOTP service by
 232 default. The <VAR>/etc/inetd.conf</VAR> usually contains a line
 233 for the BOOTP service that can be uncommented if needed.</P>
 234
 235 </BLOCKQUOTE>
 236
 237 <H2 CLASS="title"><A NAME="VERIFY">Verifying the Printer Connection</A></H2>
 238
 239 <P>To test that the IP address has been successfully assigned and
 240 that the printer is properly connected to your LAN, type:</P>
 241
 242 <PRE CLASS="command">
 243 <KBD>ping ip-address</KBD>
 244 </PRE>
 245
 246 <P>If the connection is working properly you will see something
 247 like:</P>
 248
 249 <PRE CLASS="command">
 250 <KBD>ping myprinter</KBD>

 256 </PRE>
 257
 258 <P>If not, verify that the printer or print server is connected
 259 to the LAN, it is powered on, the LAN cabling is good, and the IP
 260 address is set correctly. You can usually see the current IP
 261 address and network status by printing a configuration or test
 262 page on the device.</P>
 263
 264 <H2 CLASS="title"><A NAME="AXIS">Configuring Axis Print Servers</A></H2>
 265
 266 <P>The Axis print servers can be configured using ARP, RARP, or
