See Scott Goodwin's <a href="http://scottg.net/webtools/opennsd/modules/nsopenssl/" target="_top">excellent documentation</a> if you want to set up SSL. The second warning means that the AOLserver control panel, a special module for administering AOLserver, could not be loaded. If you're interested in configuring nscp, please see the <a href="http://www.aolserver.com/docs" target="_top">AOLserver documentation</a>. </p> </li> <li> <p> Test to see if AOLserver is working by starting <tt>Mozilla</tt> or <tt>Lynx</tt>, and surfing over to your web page: </p> <pre class="programlisting"> nsadmin:~$ lynx localhost:8000</pre> <p> You should see a "Welcome to AOLserver" page.

Start by viewing your AOLserver log, which is in <tt>/usr/local/aolserver/log/server.log</tt>. You should also try to find lines of the form:</p> <pre class="programlisting"> [01/Jun/2000:12:11:20][5914.2051][-nssock-] Notice: nssock: listening on http://localhost.localdomain:8000 (127.0.0.1:8000) [01/Jun/2000:12:11:20][5914.2051][-nssock-] Notice: accepting connections</pre> <p>If you can find these lines, try entering the URL the server is listening on. If you cannot find these lines, there must be an error somewhere in the file. Search for lines beginning with the word <tt>Error</tt> instead of <tt>Notice</tt>.</p> <p>The <tt>sample-config.tcl</tt> file grabs your address and hostname from your OS settings. </p> <pre class="programlisting"> set hostname [ns_info hostname] set address [ns_info address]</pre> <p>If you get an error that nssock can't get the requested address, you can set these manually:</p> <pre class="programlisting"> #set hostname [ns_info hostname] set hostname 127.0.0.1 #set address [ns_info address] set address 127.0.0.1</pre> <p> If you get an error that nssock can't assign the requested port, then that port may already be taken by another service. Try specifying a different port in the config file. </p> </div> <p><div class="cvstag">($Id: aolserver.html,v 1.1 2002/07/09 17:34:57 rmello Exp $)</div></p> </div> <div class="navfooter"> <hr> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"> <a accesskey="p" href="postgres.html">Prev</a> </td> <td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td> <td width="40%" align="right"> <a accesskey="n" href="openacs.html">Next</a> </td> </tr> <tr> <td width="40%" align="left">Install PostgreSQL 7.1.3 </td> <td width="20%" align="center"><a accesskey="u" href="unix-install.html">Up</a></td> <td width="40%" align="right"> Install OpenACS 4.5</td> </tr> </table> <hr> <address> rmello at fslc.usu.edu </address> <address><a href="mailto:vinod@kurup.com"> vinod@kurup.com </a></address> </div> </body> </html>
