Setup FreeRADIUS for accounting
|
||
===============================
|
||
|
||
---------------------
|
||
Goal of this tutorial
|
||
---------------------
|
||
|
||
This tutorial can be used to test your Captive portal setup with radius
|
||
accounting, it's not intended to use for production setups (because we
|
||
only use simple flat files for everything). We used Ubuntu linux for
|
||
this setup, a different operating system might result in some paths
|
||
being different.
|
||
|
||
User limits on the OPNsense firewall are set right after login, the
|
||
Radius server should tell the firewall how many resources are left for
|
||
the user that logged in successfully. A normal login sequence look like
|
||
this:
|
||
|
||
[login] -> [send accounting start] -> [send interim updates while
|
||
connected] -> [on logout, send accounting stop]
|
||
|
||
-----
|
||
Setup
|
||
-----
|
||
|
||
To setup freeradius in ubuntu, execute the following command:
|
||
|
||
::
|
||
|
||
apt-get install freeradius
|
||
|
||
|
||
Arrange client access
|
||
---------------------
|
||
|
||
Edit the file /etc/freeradius/clients.conf and append a block for your
|
||
network, as sample we will use 10.211.55.0/24.
|
||
|
||
.. code-block:: php
|
||
|
||
client 10.211.55.0/24 {
|
||
secret = testing123
|
||
shortname = test-network
|
||
}
|
||
|
||
Enable daily session limits
|
||
---------------------------
|
||
|
||
Enable daily session limits, which needs accounting to signal the
|
||
clients use.
|
||
|
||
- In /etc/freeradius/sites-available/default uncomment daily in
|
||
authorize and accounting sections.
|
||
- in /etc/freeradius/radiusd.conf uncomment daily in the instantiate
|
||
section
|
||
- append to /etc/freeradius/dictionary
|
||
|
||
|
||
.. code-block:: c
|
||
|
||
ATTRIBUTE Daily-Session-Time 3000 integer
|
||
ATTRIBUTE Max-Daily-Session 3001 integer
|
||
|
||
|
||
- uncomment sradutmp in the accounting section, to be able to use the
|
||
radwho command.
|
||
|
||
--------------
|
||
Add test users
|
||
--------------
|
||
|
||
You can add your test users to /etc/freeradius/users, they should look
|
||
like this:
|
||
|
||
.. code-block:: c
|
||
|
||
"test" Cleartext-Password := "test", Max-Daily-Session := 1800
|
||
Framed-IP-Address = 10.211.55.100,
|
||
Reply-Message = "Hello, %{User-Name}"
|
||
|
||
|
||
Make sure the second and third lines are indented by a single tab
|
||
character.
|
||
|
||
This should result in a user with a maxim use per day of 1800 seconds.
|
||
|
||

|
||
Test radius
|
||
-----------
|
||
|
||
For the initial test, it might be practical to debug the traffic going
|
||
in and out from Freeradius. The next steps help you start Freeradius in
|
||
debug mode, without output to console:
|
||
|
||
|
||
.. code-block:: c
|
||
|
||
/etc/init.d/freeradius stop
|
||
freeradius -X
