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

18 # Read "man radiusd" before editing this file. See the section
19 # titled DEBUGGING. It outlines a method where you can quickly
20 # obtain the configuration you want, without running into
21 # trouble. See also "man unlang", which documents the format
24 # This configuration is designed to work in the widest possible
25 # set of circumstances, with the widest possible number of
26 # authentication methods. This means that in general, you should
27 # need to make very few changes to this file.
29 # The best way to configure the server for your local system
30 # is to CAREFULLY edit this file. Most attempts to make large
31 # edits to this file will BREAK THE SERVER. Any edits should
32 # be small, and tested by running the server with "radiusd -X".
33 # Once the edits have been verified to work, save a copy of these
34 # configuration files somewhere. (e.g. as a "tar" file). Then,
35 # make more edits, and test, as above.
37 # There are many "commented out" references to modules such
38 # as ldap, sql, etc. These references serve as place-holders.
39 # If you need the functionality of that module, then configure

50 # additional ports, you can use multiple "listen" sections.
52 # Each section make the server listen for only one type of packet,

68 # see raddb/sites-available/status
69 # coa listen for CoA-Request and Disconnect-Request
70 # packets. For examples, see the file

75 # Note: "type = proxy" lets you control the source IP used for
76 # proxying packets, with some limitations:
78 # * A proxy listener CANNOT be used in a virtual server section.
79 # * You should probably set "port = 0".
80 # * Any "clients" configuration will be ignored.
82 # See also proxy.conf, and the "src_ipaddr" configuration entry
