Radiusclient Configuration for Fedora Core 4 / 5 / 6</strong><br> (last update: 19 May 2007)</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. Older version of freeradius has the default key "testing123". Of course, it is a bad idea to use the default.</p> <hr> <strong>A5.1 radiusclient.conf </strong><br> (last update: 19 May 2007) <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>A5.2 dictionary.microsoft</strong><br> (last update: 19 May 2007)</p> <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.
