<P>
|
|
<P>This section describes how to set up the <CODE>plip</CODE> interface in
|
|
the <B>source</B> server. If you run into trouble, I suggest that
|
|
you read the
|
|
<A HREF="http://www.linuxdoc.org/HOWTO/mini/PLIP.html">PLIP MINI-HOWTO</A>.
|
|
<P>
|
|
<P>Check that your <CODE>lp</CODE> device is not set. You should
|
|
<B>not</B> have this entry:
|
|
<P>
|
|
<PRE>
|
|
$ cat /proc/devices
|
|
Character devices:
|
|
...
|
|
6 lp
|
|
...
|
|
|
|
</PRE>
|
|
<P>If you do have it, kill the <CODE>lpd</CODE> daemon and remove the
|
|
<CODE>lp</CODE> module:
|
|
<P>
|
|
<PRE>
|
|
$ /etc/rc.d/init.d/lpd.init stop
|
|
Shutting down lpd: lpd
|
|
|
|
$ rmmod lp
|
|
|
|
</PRE>
|
|
<P>If you can't remove the <CODE>lp</CODE> module then you have to
|
|
recompile the <B>kernel</B> with <CODE>lp</CODE> service as a module.
|
|
<P>Now, the "<CODE>6 lp</CODE>" line has disappeared from the
|
|
<CODE>/proc/devices</CODE> file, which is a reflection of the kernel
|
|
capabilities.
|
|
<P>You are not obliged to eliminate the lp device : the scheme may work
|
|
with lp. Without guarantee (it works for me). Check it yourself.
|
|
<P>
|
|
<P>Check that your parallel port is handled:
|
|
<P>
|
|
<PRE>

|
|
|
|
</PRE>
|
|
<P>If you don't have any directory under <CODE>/proc/parport/</CODE> then
|
|
you have to load the <CODE>parport</CODE> and <CODE>parport_pc
|
|
modules</CODE>:
|
|
<P>
|
|
<PRE>
|
|
$ insmod parport
|
|
$ insmod parport_pc
|
|
|
|
</PRE>
|
|
<P>You should see this new entry in

|

<P>I repeat the message "detected <CODE>irq 7</CODE>, use procfs to enable

|
|
<P>
|
|
<PRE>
|
|
$ echo 7 > /proc/parport/0/irq
|
|
|
|
</PRE>
|
|
<P>Using a kernel 2.4 the last command is no longer available. Use instead:

|
<PRE>
|
|
$ insmod parport
|
|
$ insmod parport_pc io=0x378 irq=7
|
|
</PRE>
|
|
<P>
|
|
<P>Check that <CODE>plip</CODE> module is loaded:
|
|
<P>
|
|
<PRE>
|
|
$ lsmod |grep plip
|
|
|
|
</PRE>
|
|
<P>If <CODE>plip</CODE> module is not loaded, then load it:
|
|
<P>
|
|
<PRE>
|
|
$ insmod plip
|
|
|
|
</PRE>
|
|
<P>You should see something like this in

<P>If you can't load the <CODE>plip</CODE> module then you have to
|
|
recompile the <B>kernel</B> with <CODE>plip</CODE> service as a

module.
|
|
<P>The syslog message says the module is loaded on the <CODE>plip0</CODE>

<P>

<P>

<P>Now you can <CODE>ping</CODE> locally the <B>source</B> server:

<P>Verify that the route to <B>target</B> exists:

|

<P>If the route doesn't exist, add it:

|
<P>
|
|
<PRE>
|
|
$ route add -host 192.168.0.1 dev plip0
|
|
|
|
</PRE>
|
|
<P>
|
|
<P>When the <B>target</B> <EM>is</EM> configured you will be able to
|
|
do a ping test:
|
|
<P>
|
|
<PRE>
|
|
$ ping target
