Introduction

Chillispot is software which provides authentication and restricted network access to clients.

Its primary use is in wireless (WiFi) networks.

For instance, suppose you are managing a wireless network in a hotel: the access points are

connected via the wired LAN to a server which works as a gateway, firewall, DNS server,

etc. Now you want the same server (either because it's desirable or because it's required by

your nation's law) to require authentication from all clients, possibly without messing around

with the configuration of the access points. And maybe you even want users to be able to

browse some sites (i.e. an internal web server or the hotel web site) without the need to

authenticate themselves. Chillispot lets you manage all of this, and some more.

Please take a look at the Chillispot.info web site to see how the software works. In a few

words, Chillispot creates a virtual private network (192.168.182.0/24, but you can change

this default setting) which it uses to dialogate with the clients and to decide who and how to

let to see the outside network. Chillispot manages the allocation of dynamic IP addresses to

clients, so you don't need other DHCP tools.

As of mid 2007, ChilliSpot appears to be dead. The developer Jens Jacobsen had

vanished, and the chillispot.org domain lapsed, but chillispot.info is a copy (with ads

inserted) of the original site. CoovaChilli has forked from ChilliSpot 1.0 and its

development also continues with an active user-base.

Notes

The ip address number 192.168.1.73, which you'll find in this document, refers to the PC

where you run chillispot, then modify it with the ip address of YOUR local machine.

Remember you have to DISABLE DHCP if enabled on your router.

Version specific Installs

This WifiDocs/ChillispotHotspot howto is a general howto, for a step by step setup guide

see:

Ubuntu 8.04

Ubuntu 7.10

Ubuntu 6.06

Requirements

The following software is required for this installation:

Chillispot 1.0

FreeRadius 1.0.x-2.1.x

Apache 2.x

MySQL 4.1.x-5.1.x

Apache 1.x and MySql 4.0.x or even 3.23.x would probably do, but the above specified versions are the latest stable ones available so

you're encouraged to stick to them.

This tutorial will show how to run all this software on a single machine. However, you could install Apache and MySQL on a separate

one, or even have 4 different machines: you'll just need to adjust the configuration parameters of each piece of software.

25/05/2011 WifiDocs/ChillispotHotspot - Communit…

help.ubuntu.com/…/ChillispotHotspot 1/18

Also, you'll need your kernel configured for generic tunneling support (and for NAT probably but that will not be covered here). A 2.6.x

kernel version is recommended.

Kernel configuration

Chillispot create a VPN, that is to say an IP tunnel. Your kernel must support this: if you're using software such as OpenVPN chances

are you're already fine. Anyhow, take a look at the following section in your kernel configuration (run the command 'modconf'): Linux

Kernel Configuration: TUN/TAP support

# sudo apt-get install modconf

# sudo modconf

Kernel/drivers/net --->

tun [Universal TUN/TAP device driver support] --->

You can either compile the TUN/TAP support inside the kernel or (as is this example) build it as a module. The name of the module will

be tun.

# sudo modprobe tun

To have the module automatically load on reboot you will need to add "tun" to the modules file

# sudo nano -w /etc/modules

add the line

..

tun

..

You'll probably also need to enable IP masquerading, NAT or what is necessary in order to let the VPN clients surf the outside

network. If you're reading this HOWTO it's likely that you already know all of this; if not, look around for specific documentation.

Port Forwarding

nano -w /etc/sysctl.conf

net/ipv4/ip_forward=1

echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward

sudo /etc/init.d/networking restart

Installing the software

Apache and MySQL

I assume you already installed Apache and MySQL, or - if not - that you are able to do that. If this is not the case, there are plenty of

tutorial out there on how to accomplish these tasks. One option is to use tasksel and select "LAMP server"

# sudo tasksel

The only important thing to do is to enable SSL features for apache. Apache configuration (See Apache SSL section below)

Chillispot

Download it from http://www.chillispot.info



# wget http://www.chillispot.info/download/chillispot_1.0_i386.deb

# sudo dpkg -i chillispot_1.0_i386.deb

Note: for amd64 architecture

# sudo apt-get install ia32-libs

# sudo dpkg -i --force-architecture chillispot_1.0_i386.deb

Note: for amd64 Ubuntu >= 10.04 download the file: chillispot_1.0-10_i386.deb

Download Link: chillispot_1.0-10_i386.deb or

# sudo apt-get install chillispot (only for x86!)

FreeRadius

You can install it from repos:

# sudo apt-get install freeradius

# sudo apt-get install freeradius-mysql

Chillispot configuration

Chillispot configuration resides in a single file, which is /etc/chilli.conf. For a single server configuration something in the shape of this will

do:

# sudo nano -w /etc/chilli.conf

radiusserver1 127.0.0.1


radiussecret theradiussecret

dns1 192.168.1.73

dhcpif eth0

uamallowed 192.168.182.1,192.168.1.73,www.google.it

uamserver https://192.168.1.73/cgi-bin/hotspotlogin.cgi

uamhomepage https://192.168.1.73/welcome.html

uamsecret theuamsecret

Let's discuss the file in detail.

Radius section




You need to specify two radius servers even if you only have one. Of course, you can enter the same server in both lines. In this case it's

localhost, as FreeRadius is on the same machine of Chillispot.


The radiussecret directive contains a (secret) word which must match the one contained in the FreeRadius configuration file. This secret

ensures we are allowed to make queries to the radius server. We'll se the radius configuration part later on.

Networking section

dns1 192.168.1.73

You need to specify the IP address of the DNS server, which will be told to clients as well. The local machine's one will be fine if the

machine operates a DNS service, otherwise enter another one such as you provider's.

dhcpif eth0

The interface to be specified is the one where the access points reside, which should be already configured with the working access

points. Be sure to disable any DHCP server bound to that interface, as Chillispot doesn't want one.



UAM section

uamallowed 192.168.182.1,192.168.1.73,www.google.it

The above line states which hosts the clients are allowed to connect without requring authentication. You must enter the IP address of the

gateway (both the VPN address and the LAN address - This is very important! In fact, you must list at least these two addresses here,

otherwise the chillispot will not work!), the IP address of the DNS server (if it's on another machine) and any other hosts you want.


This is the (secure) URL of the script which displays the login interface and manages the login. We'll discuss this further in the Apache

configuration section.

uamhomepage https://192.168.1.73/welcome.html

This is the page where all clients will be redirected when they try to surf a web site which is not in the uamallowed list. This is quite

handy, as you don't need to provide login URLs to your users: their browser gets automatically redirected here. The contents of this file

are very customizable (you can provide a full featured web page with information and the login link), and also this will be discussed later

on while talking of Apache configuration.

uamsecret theuamsecret

This is the shared secret between chillispot and hostspotlogin.cgi, which ensures that the CGI script is allowed to talk to Chillispot. It's

different than the radius secret, but you can also set them all alike (not recommended, of course).

Apache configuration

Apache (or any other webserver you like) handles the welcome page and the login requests, and therefore requires a bit of configuration.

As told before, SSL support is required by Chillispot (if you don't have it, the login manager will complain and not work). When dealing

with usernames and password and encryped connection is a good idea to use SSL in any case. See section below.

At this point there are several options. What I did was to setup a virtual host bound to http://192.168.1.73/, which is also the content of

uamhomepage variable in /etc/chilli.conf. As I wrote before, this page can contain anything you want the user to see before loggin in

(information about your place, your network, the rules, ...), but in any case it should also feature a link to Chillispot server "prelogin"

page . That is to say, in it's basic form the index.html file of your web site has to be:

<a href="http://192.168.182.1:3990/prelogin">Click here to login</a>

The Chillispot server bound to port 3990 will redirect the browser to whatever you specified in the uamserver line of /etc/chilli.conf. In

this case it's:

https://192.168.1.73/cgi-bin/hotspotlogin.cgi

The hotspotlogin.cgi manages the actual login. The good thing is that you don't have to write it from scratch. Just type in:

# sudo cp /usr/share/doc/chillispot/hotspotlogin.cgi.gz /usr/lib/cgi-bin

# sudo gunzip /usr/lib/cgi-bin/hotspotlogin.cgi.gz

# sudo chmod 755 /usr/lib/cgi-bin/hotspotlogin.cgi

This presumes your Apache is configured to run cgi-scripts of course.

There's only one change needed for hotspotlogin.cgi: locate the $uamsecret assignement at the top of the file and set it to the value of

uamsecret in /usr/lib/cgi-bin/hotspotlogin.cgi. In our example:

# sudo nano -w /usr/lib/cgi-bin/hotspotlogin.cgi

$uamsecret = "theuamsecret";

$userpassword=1;

You can then edit this file at your pleasure to customize the appearence of the login screen.



FreeRadius configuration

Authentication

FreeRadius is a complex piece of software but (luckily) the features needed for a basic or even common setup are a few, and therefore

also the configuration is fairly straightforward.

The first file to look into is /etc/freeradius/clients.conf. You need to have something like this into it:

# nano -w /etc/freeradius/clients.conf

client 127.0.0.1 {

secret = theradiussecret

shortname = localhost

nastype = other

}

There should already be a client 127.0.0.1 section uncommented, so you may just need to edit that one. If you're not connecting from

localhost you can vary the IP address accordingly, or even specify a class: the comments in the file explain everything.

The next file to edit is /etc/freeradius/sql.conf. It is already preconfigured for MySQL, but you can change it to work with Postgres,

Oracle or MS-SQL. The other options are fairly intuitive, in the sense that you only have to specify the login data for the MySQL server

and database. You can leave the remaining settings alone. In my example I have:

# nano -w /etc/freeradius/sql.conf

# Connect info

server = "localhost"

login = "freeradius"

password = "mysuperpassword"

# Database table configuration

radius_db = "radius"

Difficult, huh?

The last file which requires some modification is /etc/freeradius/radiusd.conf. Browse the file, look for the sql directive in the authorize

section, and uncomment it: this is needed in order to have FreeRadius use the SQL module for authentication.

# nano -w /etc/freeradius/radiusd.conf

authorize {

preprocess

# auth_log

# attr_filter

chap

mschap

# digest

# IPASS

suffix

# ntdomain

eap

files

sql

# etc_smbpasswd

# ldap

# daily

# checkval

pap

}

Note: for freeradius2

1) uncomment the line #$INCLUDE sql.conf

2) "authorize" section is in:

# nano -w /etc/freeradius/sites-available/default



Be sure to restart FreeRadius after these changes

# sudo /etc/init.d/freeradius restart

Accounting

FreeRadius comes already preconfigured for accounting, and it stores that information in files under the /var/log/radius/radacct directory.

However. you might want to configure it to use MySQL instead of files for accounting also. To accomplish this task look for the

accounting section in /etc/freeradius/radiusd.conf. It should be configured like this:

# sudo nano -w /etc/freeradius/radiusd.conf

accounting {

unix

radutmp

sql

}

(I stripped all the commented stuff out)

I only made two changes:

I added the sql option, which causes FreeRadius to store accounting information on the table radacct of the SQL database it uses.

I removed the detail option, so that it doesn't log that information on files anymore. You can leave this where it is if you want both

logs.

MySQL configuration

FreeRadius requires a MySQL database with a predefinied structure where to look for user/password pairs and (if desired) store

accounting information. Log into the MySQL client with root privildges and launch the following commands, or a variation of them which

suits your needs:

# sudo mysql -u root -p

mysql> CREATE DATABASE radius;

mysql> GRANT ALL PRIVILEGES ON radius.* to 'freeradius'@'localhost' IDENTIFIED BY 'mysuperpassword';

mysql> FLUSH PRIVILEGES;

mysql> quit

Then import the SQL schema:

# sudo zcat /usr/share/doc/freeradius/examples/mysql.sql.gz | mysql -u freeradius -p mysuperpassword

radius

Note: for freeradius 2

# mysql -u freeradius -p radius < /etc/freeradius/sql/mysql/schema.sql

# mysql -u freeradius -p radius < /etc/freeradius/sql/mysql/nas.sql

If this way doesn't work for you, just import the above file through phpmyadmin.

As you will see, this creates several tables. You probably just need to use one of those: radcheck. This table has the following structure:

Field Type Null Key Default Extra

id int(11) unsigned PRI NULL auto_increment

UserName varchar(64) MUL

Attribute varchar(32)



op varchar(2) ==Value varchar(253)

The id is auto-incremented and op defaults to the correct value, so you just need to enter the other fields in this fashion:

mysql> INSERT INTO radcheck (UserName, Attribute, Value) VALUES ('aika', 'User-Password',

'myaikapassword');

That should be enough. You can then use whatever client or interface you want to populate the users database.

Firewall configuration (easy way)

install firestarter

#sudo apt-get install firestarter

run the wizard (the first time you run it, wizard should be automatic)

Select "enable internet connection sharing"

Set the device which is connected to internet (ethX)

Set 'tun0' as your local network connected device (tun0 device will be shown with chilli running correctly)

DO NOT enable DHCP (IMPORTANT)

Confirm the wizard or close preferences

Go to 'policy' tab

Add an 'inbound traffic policy' rule in the 'allow connections from host' pane where allowed ips are 192.168.182.2/24 (which is

from 192.168.182.2 to 192.168.182.255)

you also might need this (I'm not sure)

# sudo apt-get install dnsmasq ipmasq

# sudo /etc/init.d/dnsmasq restart

# sudo dpkg-reconfigure ipmasq

[Reconfigure ipmasq to start after networking has been started]

Firewall configuration (difficult way) [to be skipped if you followed the easyway]

Note: Type all the following commands in a root terminal, DO NOT use sudo.

The services you're going to use require you to open a few ports on your firewall. This HOWTO assumes you have already protected

your computer somehow, and therefore only lists the changes you need to do.

You basically need to do the following:

Open port 443/TCP at least to the 192.168.182.0/24 subnet: this is the Apache HTTPS port.

Open port 3990/TCP at least to the 192.168.182.0/24 subnet: this is the port of Chillispot web server.

Open port 1812/UDP to 127.0.0.1 (probably all ports are already open to localhost): this is the port FreeRadius listens to, and

Chillispot connects to it using that.

Open port 67/UDP to the VPN (probably the tun0 interface): this is used by Chillispot DHCP server to get requests for IP

address registration.

This can change very much depending on your configuration, but if you stick to this example that's it. You'll probably also want to

configure NAT at this point.

In order to enable packet forwarding you should change the following line in /etc/network/options:

nano -w /etc/network/options

ip_forward=yes

Then you have to restart networking:



# /etc/init.d/networking restart

. Start by configuring the network card that interfaces to the other computers on you network:

# ip addr add 1.2.3.4/56 dev ethX

where ethX is the network card and 1.2.3.4/56 is your desired server IP address with prefix length (Usually 192.168.0.1/24 is used)

. Then configure the NAT as follows:

# iptables -t nat -A POSTROUTING -o ethX -j MASQUERADE

where ethX is the network card that the Internet is coming from

# echo 1 > /proc/sys/net/ipv4/ip_forward

. Install dnsmasq and ipmasq using apt-get:

# apt-get install dnsmasq ipmasq

. Restart dnsmasq:

# /etc/init.d/dnsmasq restart

. Reconfigure ipmasq to start after networking has been started:

# dpkg-reconfigure ipmasq

. Repeat steps 1 and 2.

Apache2 SSL

This guide will help you setup SSL with apache2.

Generate the certificate

If you are running a 7.04 distribution you may execute the folowing command.

sudo make-ssl-cert /usr/share/ssl-cert/ssleay.cnf /etc/apache2/ssl/apache.pem

Enable the SSL module

sudo a2enmod ssl

Listen to port 443

sudo bash

echo "Listen 443" >> /etc/apache2/ports.conf

Create and enable the SSL site

sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/ssl

sudo nano -w /etc/apache2/sites-available/ssl

Modify it so it looks something like this

NameVirtualHost *:443

<virtualhost *:443>

ServerAdmin webmaster@localhost

phpMyPrepaid and MySQL

Get phpMyPrepaid here:

ftp://ftp.heanet.ie/mirrors/download.sourceforge.net/pub/sourceforge/p/ph/phpmyprepaid/phpMyPrepaid.0.1.3RC1.tar

(NOTE: There is a newer version available from http://www.chillispot.org/patch/ . Checkout the Chillispot forums for discussion -SW)

Some files need to be adjusted, but it's just a question of links. Read the INSTALL file.

Install freeradius 1.1.0. You'll need the package from http://apt-repo.ttec.com/binaries/ [this applies to breezy only. Dapper

comes with correct freeradius version now] (NOTE: this is required because we need the sqlcounter module that is stable in the

1.1 release -SW)

You need to download freeradius_1.1.0~pre0~cvs20051129-0-JM-2_i386.deb and freeradius-mysql_1.1.0~pre0~cvs20051129-0-

JM-2_i386.deb (NOTE: these have been superseded. See my notes below on how to backport these from Dapper yourself -SW)

add 'ATTRIBUTE Max-All-Session 3000 integer' without quotes to /etc/freeradius/dictionary

Modifications needed to /etc/freeradius/radiusd.conf [can only use root user, not sudo]



under the "$INCLUDE ${confdir}/sql.conf" add:

sqlcounter noresetcounter {

counter-name = Max-All-Session-Time

check-name = Max-All-Session

sqlmod-inst = sql

key = User-Name

reset = never

query = "SELECT SUM(AcctSessionTime) FROM radacct where UserName='%{%k}'"

}

1. "instantiate" section must be as follow:

instantiate {

exec

expr

noresetcounter

}

1. "authorize" section must be as follow:

authorize {

preprocess

chap

mschap

suffix

sql

noresetcounter

}

Rough instructions for PHPMyPrepaid:

Extract the phpMyPrepaid file to a directory on your webserver eg /var/www/html/myprepaid

Edit the dbconnect.php file in the phpMyPrepaid directory and enter the username and password for your MySQL radius database.

IMPORTANT Save this file behind your web directory or your passwords will be easy to hack.

Edit config.inc.php and change the line that points to dbconnect to wherever you have saved dbconnect.php

In your web browser got to http://yoursite.com/whereveryouputphpmyprepaid/ and create some tickets.

Check your database to see if the users have been setup in radcheck. Launch FreeRadius as root with this command radiusd -xxyx -l

stdout. Pick a user and password from your database and try to login from a wireless client.

Tips

Launch Chillispot using 'chilli --debug --fg' to see what's happening while it works.

The same applies to Freeradius. Use 'freeradius -x'

mysql5 [provided in dapper] currently gives some problems if you try to use it through phpmyadmin. Just launch 'sudo chmod

og=rx /var/run/mysqld' to solve them.

There are 2 useful options (expecially the first one) which need to be added in phpMyPrepaid:

Idle-Timeout: Time after which the user is disconnected if not browsing.[useful if the user forget to logout correctly]

Session-Timeout: Time after which the user is disconnected. However he can reconnect if has some time left.

To add the first option you have to modify the phpMyPrepaid/CrCards/DBinsert.php file and add before "}"

(consider that 60 corrisponds to 60 sec):

$q3= "INSERT INTO radreply (UserName , Attribute, op, Value) VALUES('$id','Idle-

Timeout',':=','60')";

$insert3 = mysql_query($q3) or die(mysql_error());

Hotspotlogin.php

This file is an easier to be modified substitute for hotspotlogin.cgi. Change the uamsecret password, put it in /var/www and change

chilli.conf as follow:

Backporting FreeRadius to Breezy from Dapper

I know Dapper is nearly here but I needed to deply this now (2006-03-09)! Of course, the version numbers shown were correct at the

time of printing, they may change when Dapper is released.

Backporting yourself is preferred to installing binary packages from unknown/untrusted sources. Not to cast any doubt on the source

that was listed but I have no idea who they are, do you? Backporting from Dapper gives you the benefit of knowing that the package

configuration conforms to the Ubuntu guidelines and you know that no changes have been to the source code from the Ubuntu

repositiories. It sounds daunting but the steps are fairly straight forward.

I would start freeradius before you upgrade or you'll get errors later when the restart commands fail!

Start by adding the Dapper source repositories to your /etc/apt/sources.list. Simply replace deb with deb-src in your favourite mirror

entries eg

deb-src http://au.archive.ubuntu.com/ubuntu dapper main restricted universe

Make a directory to build the new packages in and cd to it.

To ensure you have all the build dependencies execute:

$ sudo apt-get build-dep freeradius debhelper lsb

The first thing to do is upgrade debhelper:

$ fakeroot apt-get -b source debhelper

$ sudo dpkg -i debhelper_5.0.7ubuntu4_all.deb

then you have to upgrade lsb-base (you only need lsb-base, if you try and install lsb you'll get a whopping numberof packages

upgraded):

$ fakeroot apt-get -b source lsb

$ sudo dpkg -i lsb-base_3.0-12ubuntu3_all.deb



Finally, you can build and install freeradius 1.1

$ fakeroot apt-get -b source freeradius

$ sudo dpkg -i freeradius_1.1.0-1_i386.deb freeradius-mysql_1.1.0-1_i386.deb

If that's successful continue on with Gabriele's great HOWTO...

If you run into any problems, try using the command "sudo apt-get -f install" which will try and install any packages that are required.

If you think anything should be clarified feel free to drop me an email.

Good luck, SimonWong.
