<para>
Debian users: we do not recommend installing Debian packages for
Aolserver or Postgres. Several people have
reported problems while trying to install using apt-get
instead of from source. If you have the time to debug these
and submit what you did, that's great, but if not, you
should stick to installing from source.

</para>
<para>Now, we'll run a quick test to ensure AOLserver is running
correctly. We'll use the sample config file provided with
AOLserver. This file will attempt to guess your IP address and
hostname. It will then start up the server at port 8000 of that
IP address.</para>

<para>The first warning, about nsssl, can be ignored. We won't be using nsssl; we'll be using nsopenssl instead, and we haven't fully configured it yet. The nscp warning refers to the fact that, without a user and password in the config file, the administrative panel of AOLserver won't load. We don't plan to use it and can ignore that error as well. Any other warning or error is unexpected and probably a problem.</para>
<para>
Test to see if AOLserver is working by starting
<computeroutput>Mozilla</computeroutput> or
<computeroutput>Lynx</computeroutput> <emphasis>on the same
computer</emphasis> and surfing over to your web page. If
you browse from another computer and the sample config file
didn't guess your hostname or ip correctly, you'll get a
false negative test.

<para>
You should see a "Welcome to AOLserver" page. If this
doesn't work, try going to
<computeroutput>http://127.0.0.1:8000/</computeroutput>. If this
still doesn't work, check out the <xref
linkend="install-aolserver-troubleshooting"/> section below. Note that you will not be able to browse to the web page from another machine, because AOLserver is only listening to the local address.

<para>Shutdown the test server:</para>
<screen>[root aolserver]# <userinput>killall nsd</userinput>

<para>
The <computeroutput>killall</computeroutput> command will kill

<para>If you can't view the welcome page, it's likely there's a

<para>
If you can find these lines, try entering the URL the server is

somewhere in the file. Search for lines beginning with the word
<computeroutput>Error</computeroutput> instead of
<computeroutput>Notice</computeroutput>.

<para>
If you get an error that nssock can't get the requested address, you
can set these manually. If you type 0.0.0.0, AOLserver will try to
listen on all available addresses. <emphasis>Note</emphasis>:
