#	As of 2.0.0, FreeRADIUS supports virtual hosts using the
#	"server" section, and configuration directives.
#
#	Virtual hosts should be put into the "sites-available"
#	directory.  Soft links should be created in the "sites-enabled"
#	directory to these files.  This is done in a normal installation.
#
#	If you are using 802.1X (EAP) authentication, please see also
#	the "inner-tunnel" virtual server.  You will likely have to edit
#	that, too, for authentication to work.
#

#
#	Read "man radiusd" before editing this file.  See the section
#	titled DEBUGGING.  It outlines a method where you can quickly
#	obtain the configuration you want, without running into
#	trouble.  See also "man unlang", which documents the format
#	of this file.
#
#	This configuration is designed to work in the widest possible
#	set of circumstances, with the widest possible number of
#	authentication methods.  This means that in general, you should
#	need to make very few changes to this file.
#
#	The best way to configure the server for your local system
#	is to CAREFULLY edit this file.  Most attempts to make large
#	edits to this file will BREAK THE SERVER.  Any edits should
#	be small, and tested by running the server with "radiusd -X".
#	Once the edits have been verified to work, save a copy of these
#	configuration files somewhere.  (e.g. as a "tar" file).  Then,
#	make more edits, and test, as above.
#
#	There are many "commented out" references to modules such
#	as ldap, sql, etc.  These references serve as place-holders.
#	If you need the functionality of that module, then configure
#	it in radiusd.conf, and un-comment the references to it in
#	this file.  In most cases, those small changes will result
#	in the server being able to connect to the DB, and to
#	authenticate users.

server default {
#
#  If you want the server to listen on additional addresses, or on
#  additional ports, you can use multiple "listen" sections.
#
#  Each section make the server listen for only one type of packet,
#  therefore authentication and accounting have to be configured in
#  different sections.
#
#  The server ignore all "listen" section if you are using '-i' and '-p'
#  on the command line.
#
listen {
	#  Type of packets to listen for.
	#  Allowed values are:
	#	auth	listen for authentication packets
	#	acct	listen for accounting packets
	#       auth+acct listen for both authentication and accounting packets
	#	proxy   IP to use for sending proxied packets
	#	detail  Read from the detail file.  For examples, see
	#               raddb/sites-available/copy-acct-to-home-server
	#	status  listen for Status-Server packets.  For examples,
	#		see raddb/sites-available/status
	#	coa     listen for CoA-Request and Disconnect-Request
	#		packets.  For examples, see the file
	#		raddb/sites-available/coa
	#
	type = auth

	#  Note: "type = proxy" lets you control the source IP used for
	#        proxying packets, with some limitations:
	#
	#    * A proxy listener CANNOT be used in a virtual server section.
	#    * You should probably set "port = 0".
	#    * Any "clients" configuration will be ignored.
	#
	#  See also proxy.conf, and the "src_ipaddr" configuration entry
	#  in the sample "home_server" section.  When you specify the
	#  source IP address for packets sent to a home server, the
	#  proxy listeners are automatically created.

	#  ipaddr/ipv4addr/ipv6addr - IP address on which to listen.
	#  If multiple ones are listed, only the first one will
	#  be used, and the others will be ignored.
	#
	#  The configuration options accept the following syntax:
	#
	#  ipv4addr - IPv4 address (e.g.192.0.2.3)
	#  	    - wildcard (i.e. *)
	#  	    - hostname (radius.example.com)
	#  	      Only the A record for the host name is used.
	#	      If there is no A record, an error is returned,
	#	      and the server fails to start.
	#
	#  ipv6addr - IPv6 address (e.g. 2001:db8::1)
	#  	    - wildcard (i.e. *)
	#  	    - hostname (radius.example.com)
	#  	      Only the AAAA record for the host name is used.
	#	      If there is no AAAA record, an error is returned,
	#	      and the server fails to start.
	#
	#  ipaddr   - IPv4 address as above
	#  	    - IPv6 address as above
	#  	    - wildcard (i.e. *), which means IPv4 wildcard.
	#	    - hostname
	#	      If there is only one A or AAAA record returned
	#	      for the host name, it is used.
	#	      If multiple A or AAAA records are returned
	#	      for the host name, only the first one is used.
	#	      If both A and AAAA records are returned

	#  Some systems support binding to an interface, in addition
	#  to the IP address.  This feature isn't strictly necessary,
	#  but for sites with many IP addresses on one interface,
	#  it's useful to say "listen on all addresses for eth0".

	#
	#  If this configuration is used, then the global list of clients

#  Authentication.
#
#
#  This section lists which modules are available for authentication.

#  that a module from the 'authorize' section adds a configuration
#  attribute 'Auth-Type := FOO'.  That authentication type is then
#  used to pick the appropriate module from the list below.
#

#  In general, you SHOULD NOT set the Auth-Type attribute.  The server
#  will figure it out on its own, and will do the right thing.  The
#  most common side effect of erroneously setting the Auth-Type
#  attribute is that one authentication method will work, but the
#  others will not.
#
#  The common reasons to set the Auth-Type attribute by hand
#  is to either forcibly reject the user (Auth-Type := Reject),
#  or to or forcibly accept the user (Auth-Type := Accept).
#
#  Note that Auth-Type := Accept will NOT work with EAP.
#
#  Please do not put "unlang" configurations into the "authenticate"
#  section.  Put them in the "post-auth" section instead.  That's what
#  the post-auth section is for.

	#    * it could not get the packet due to firewall issues

	#    * the users system might not like the servers cert

	#
	#  All that we can know on the FreeRADIUS side is that we sent

	#  will tell you why the client gave up.  The answers are in
