<p><strong>11. Software for R</strong><strong>adius Setup</strong></p>
<p>In additional to the software we installed in the previous sections, we need two more. Freeradius is one of them. FC4 comes with freeradius-1.0.2-2 but it is broken. At the time of writing, the latest one is freeradius-1.0.4-1.FC4.1. Get it from yum as it has quite a few dependences. yum will resolve all required dependences automagically.</p>
<blockquote>
<pre>[root@pptp ~]# yum install freeradius </pre>
</blockquote>
<p>The second software you will need is radiusclient. Get the FC4 rpm, radiusclient-0.3.2-0.2.fc4.rf.i386.rpm, from <a href="http://rpmforge.net/user/packages/radiusclient/">RPMforge</a>. Install it with "rpm -ivh".</p>
<hr>
<p><strong><a name="rclient"></a>12. Radiusclient</strong></p>
<p>Radiusclient is required because the pppd radius plugin relies on it. There are a few configuration files in /etc/radiusclient to look at. The first one is /etc/radiusclient/servers which specify the radius server name and key. We have the radius server in the same box. So the file is like this:</p>
<blockquote>
<pre>#Server Name or Client/Server pair Key<br>#---------------- ---------------<br>localhost testing123 </pre>
</blockquote>
<p>The key is the secret of the radius server which is specified in /etc/raddb/clients.conf. The default is testing123. Of course, it is a bad idea to use the default.</p>
<hr>
<a name="rclientconf"></a><strong>12.1 radiusclient.conf</strong>
<p>The main configuration file for radiusclient is /etc/radiusclient/radiusclient.conf. Here is how it should be when all remarks are stripped off:</p>
<blockquote>
<pre>auth_order radius
login_tries 4
login_timeout 60
nologin /etc/nologin
issue /etc/radiusclient/issue
authserver localhost
acctserver localhost
servers /etc/radiusclient/servers
dictionary /etc/radiusclient/dictionary
login_radius /usr/sbin/login.radius
seqfile /var/run/radius.seq
mapfile /etc/radiusclient/port-id-map
default_realm
radius_timeout 10
radius_retries 3</pre>
</blockquote>
<p>Basically, all of the lines are default. I have not changed anything.</p>
<hr>
<strong><a name="dict"></a>12.2 dictionary.microsoft</strong>
<p>In /etc/radiusclient, there is a file called dictionary. Add the following line to the end of the file.</p>
<blockquote>
<pre>INCLUDE /etc/radiusclient/dictionary.microsoft</pre>
</blockquote>
<p>The file, dictionary.microsoft, is not included in the radiusclient. We can modify the one from freeradius so that it can be used by pppd.</p>
<p>First of all, copy the freeradius one, /usr/share/freeradius/dictionary.microsoft, to /etc/radiusclient. Then change the word "octets" to "string" in the file. Add the word Microsoft to all attributes. Here is my version: </p>
