<h1 class="SECT1"><a name="AEN885">2.7. Checking System
Installation with <b class="APPLICATION">checkpc</b></a></h1>
<p>The <b class="APPLICATION">checkpc</b> program is used to
make sure that the spool directories and files used by <b
class="APPLICATION">LPRng</b> have the correct permissions
and are in place. By default, <b class=
"APPLICATION">checkpc</b> will check permissions and report
if there are any problems. You should run this as <tt class=
"LITERAL">root</tt>. For example:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN893"></a>
<pre class="SCREEN">
<tt class="PROMPT">h4: {2} #</tt> <tt class=
"USERINPUT"><b>checkpc</b></tt>
Warning - No configuration file '/etc/lpd.conf'
Warning - No lpd only printcap file found in '/etc/lpd_printcap'
Warning - ** cannot open '/var/run/lpd.printer' - 'Permission denied'
Warning - bad directory - /var/spool/lpd/lp
Warning - Printer 'lp' spool dir '/var/spool/lpd/lp' needs fixing
</pre>
</div>
<br>
<br>
<p>In the above example, <b class="APPLICATION">checkpc</b>
has discovered that the <tt class="FILENAME">lpd.conf</tt>
file is missing. This is a serious problem and indicates that
the software may be incorrectly installed.</p>
<p>The <tt class="LITERAL">lpd only printcap</tt> message is
usually of concern to administrators who wish to use some of
<b class="APPLICATION">LPRng</b>'s more exotic configuration
options. It is possible to have separate <tt class=
"FILENAME">printcap</tt> files for client and server
programs. This is useful when <tt class=
"FILENAME">printcap</tt> files get extremely large and cuts
down substantially on system management problems.</p>
<p>The <tt class="LITERAL">permission denied</tt> message for
<tt class="FILENAME">/var/run/lpd.printer</tt> is serious, as
the <b class="APPLICATION">lpd</b> server uses this as a lock
file.</p>
<p>The <tt class="LITERAL">bad directory</tt> message about
the spool directory is usually caused by wrong permissions or
a missing directory.</p>
<p>The <tt class="COMMAND">checkpc -f</tt> (fix) option
causes <b class="APPLICATION">checkpc</b> to take action to
rectify errors. The <tt class="COMMAND">checkpc -f -V</tt>
(verbose) option causes the fixup activity to be displayed a
well:</p>
<div class="INFORMALEXAMPLE">
<a name="AEN915"></a>
<pre class="SCREEN">
<tt class="PROMPT">h4: {3} #</tt> <tt class=
"USERINPUT"><b>checkpc -f -V</b></tt>
