Remove mention of plip0, the parallel-port network device. As Diane

Bruce succintly explains it: "PLIP is obsolescent, blah blah blah."

<title>Setting Up PLIP</title>
<para>First, you have to get a laplink cable. Then, confirm
that both computers have a kernel with &man.lpt.4; driver
support:</para>
<screen>&prompt.root; <userinput>grep lp /var/run/dmesg.boot</userinput>
lpt0: &lt;Printer&gt; on ppbus0
lpt0: Interrupt-driven port</screen>
<para>The parallel port must be an interrupt driven port, you
should have lines similar to the following in your in the
<filename>/boot/device.hints</filename> file:</para>
<programlisting>hint.ppc.0.at="isa"
hint.ppc.0.irq="7"</programlisting>
<para>Then check if the kernel configuration file has a
<literal>device plip</literal> line or if the
<filename>plip.ko</filename> kernel module is loaded. In both
cases the parallel networking interface should appear when you
use the &man.ifconfig.8; command to display it:</para>
<screen>&prompt.root; <userinput>ifconfig plip0</userinput>
plip0: flags=8810&lt;POINTOPOINT,SIMPLEX,MULTICAST&gt; mtu 1500</screen>
<para>Plug the laplink cable into the parallel interface on
both computers.</para>
<para>Configure the network interface parameters on both sites
as <username>root</username>. For example, if you want to
connect the host <hostid>host1</hostid> with another machine
<hostid>host2</hostid>:</para>
<programlisting> host1 &lt;-----&gt; host2
IP Address 10.0.0.1 10.0.0.2</programlisting>
<para>Configure the interface on <hostid>host1</hostid> by
doing:</para>
<screen>&prompt.root; <userinput>ifconfig plip0 10.0.0.1 10.0.0.2</userinput></screen>
<para>Configure the interface on <hostid>host2</hostid> by
doing:</para>
<screen>&prompt.root; <userinput>ifconfig plip0 10.0.0.2 10.0.0.1</userinput></screen>
<para>You now should have a working connection. Please read the
manual pages &man.lp.4; and &man.lpt.4; for more
details.</para>
<para>You should also add both hosts to
<filename>/etc/hosts</filename>:</para>
<programlisting>127.0.0.1 localhost.my.domain localhost
10.0.0.1 host1.my.domain host1
10.0.0.2 host2.my.domain host2</programlisting>
<para>To confirm the connection works, go to each host and ping
the other. For example, on <hostid>host1</hostid>:</para>
<screen>&prompt.root; <userinput>ifconfig plip0</userinput>
plip0: flags=8851&lt;UP,POINTOPOINT,RUNNING,SIMPLEX,MULTICAST&gt; mtu 1500
