CoovaChilli - chilli.conf(5)

NAME

chilli.conf - Chilli Configuration

DESCRIPTION

chilli has many configuration parameters which can either be used on the command line or in a configuration file. When on the command line, options are prefixed with two dashes and may or may not have an equal sign, for instance, these are equivalent:

chilli --uamallowed www.coova.org --uamanydns

chilli --uamallowed="www.coova.org" --uamanydns

Options that do not have arguments behave the same way, just without any equal sign or second argument. When in the configuration file, options must not have any dashes, but can still be used with or without the equal sign, as in:

uamallowed "www.coova.org"

uamallowed=www.coova.org

uamanydns

Options given on the command line take precedent over any options defined in a configuration file. The default main configuration file is /usr/local/etc/chilli.conf which can be overridden using the --conf option (or just --c for short) on the command line. Configuration files may also include other configuration files as in:

include /path/to/chilli/configfile.conf

Blank lines and comment lines starting with '#' are also allowed in the configuration file.

OPTIONS

As mentioned above, all options below are able to be put on the command line (prefixed with '--') or in a configuration file. A few options, shown below with the leading dashes, are typically only used on the command line.

--help
Or -h for short; prints help and exits (command line)
--version
Or -V for short; prints version and exits (command line)
--fg
Or -f for short; runs server in foreground (command line)
--debug
Or -d for short; run server in debug mode (command line)
--debugfacility level
Increase the debug level (command line) (should be named debuglevel)
--conf file
Or -c file for short; use the configuration file file instead of the default show in FILES (command line)

The file to use as the Administrative-User update file. When used in combination with the above adminuser and adminpasswd options, ChilliSpot-Config RADIUS attributes found in the Administrative-User Access-Accept are put into the specified file. If the file changes, chilli will reload it's configuration (it's assumed that this file is included into the chilli configuration file).
swapoctets
Swap the meaning of "input octets" and "output octets" as it related to RADIUS attribtues.
openidauth
Allows OpenID authentication by sending ChilliSpot-Config=allow-openidauth in RADIUS Access-Requests to inform the RADIUS server of the option.
wpaguests
Allows WPA Guest authentication by sending ChilliSpot-Config=allow-wpa-guests in RADIUS Access-Requests to inform the RADIUS server of the option. The RADIUS may return with an Access-Accept containing ChilliSpot-Config=require-uam-auth to give WPA access, but enforce the captive portal.
coaport port
UDP port to listen to for accepting radius disconnect requests.
coanoipcheck
If this option is given no check is performed on the source IP address of radius disconnect requests. Otherwise it is checked that radius disconnect requests originate from radiusserver1 or radiusserver2.
proxylisten host
Local interface IP address to use for accepting radius requests.
proxyport port
UDP Port to listen to for accepting radius requests.
proxyclient host
IP address from which radius requests are accepted. If omitted the server will not accept radius requests.
proxysecret secret
Radius shared secret for clients. If not specified it defaults to radiussecret.
dhcpif dev
Ethernet interface to listen to for the downlink interface. This option must be specified.
usetap
Use the TAP interface instead of TUN (Linux only).
nexthop mac-address
Specify a MAC address which is the layer 2 next hop to route packets to (used with usetap only).
rtmonfile file
Option to launch the chilli_rtmon daemon with the specified file as the update file. The chilli_rtmon daemon will update the file with a nexthop configuration entry before sending chilli a SIGHUP to reread it's configuration.
tcpwin number
Specify an integer value for the TCP Window and TCP Maximum Segment Size. If set, packets are rewritten with the values for both Window and MSS.
tundev dev
The specific device to use for the TUN/TAP interface.
txqlen bytes
The TX queue length to set on the TUN/TAP interface.
dhcpmac address
MAC address to listen to. If not specified the MAC address of the interface will be used. The MAC address should be chosen so that it does not conflict with other addresses on the LAN. An address in the range 00:00:5E:00:02:00 - 00:00:5E:FF:FF:FF falls within the IANA range of addresses and is not allocated for other purposes.

The dhcpmac option can be used in conjunction with access filters in the access points, or with access points which supports packet forwarding to a specific MAC address. Thus it is possible at the MAC level to separate access point management traffic from user traffic for improved system security.

The dhcpmac option will set the interface in promisc mode.

lease seconds
Use a DHCP lease of seconds (default 600).
dhcpstart number
Where to start assigning IP addresses (default 10).
dhcpend number
Where to stop assigning IP addresses (default 254).
dhcpbroadcast
Always respond to DHCP to the broadcast IP, when no relay.
eapolenable
If this option is given IEEE 802.1x authentication is enabled. ChilliSpot will listen for EAP authentication requests on the interface specified by dhcpif. EAP messages received on this interface are forwarded to the radius server.
uamserver url
URL of web server to use for authenticating clients.
uamhomepage url
URL of homepage to redirect unauthenticated users to. If not specified this defaults to uamserver.
wisprlogin url
A specific URL to be given in WISPr XML LoginURL. Otherwise, uamserver is used.
uamsecret secret
Shared secret between uamserver and chilli. This secret should be set in order not to compromise security.
uamlisten host
IP address to listen to for authentication of clients. If an unauthenticated client tries to access the Internet she will be redirected to this address.
uamport port
TCP port to bind to for authenticating clients (default = 3990). If an unauthenticated client tries to access the Internet she will be redirected to this port on the uamlisten IP address.
uamuiport port
TCP port to bind to for only serving embedded content.
uamallowed domain
Comma separated list of resources the client can access without first authenticating. Each entry in the list can be a domain names, IP addresses, or network segment. Example:

uamallowed www.chillispot.org,10.11.12.0/24

Where each entry can be made more specific by specifying a protocol and port in the format host/network:port or protocol:host/network or protocol:host/network:port where protocol is a protocol name from /etc/protocols, host/network is just as above (a domain, IP, or network), and port is a port number. Example:

uamallowed coova.org:80,icmp:coova.org

Adding to your walled garden is useful for allowing access to a credit card payment gateways, community website, or other publicly available resources.

ChilliSpot resolves the domain names to a set of IP addresses during startup. Some big sites change the returned IP addresses for each lookup. This behaviour is not compatible with this option. Domain names in the list do get updated periodically based on the interval option.

It is possible to specify the uamallowed option several times. This is useful if many domain names have to be specified.

uamdomain domain
One domain prefix per use of the option; defines a list of domain names to automatically add to the walled garden. This is done by the inspecting of DNS packets being sent back to the subscriber.
uamlogoutip ipaddress
Use this IP address to instantly logout a client accessing it (defaults to 1.1.1.1).
defsessiontimeout seconds
Default session timeout (max session time) unless otherwise set by RADIUS (defaults to 0, meaning unlimited).
defidletimeout seconds
Default idle timeout (max idle time) unless otherwise set by RADIUS (defaults to 0, meaning unlimited).
definteriminterval seconds
Default interim-interval for RADIUS accounting unless otherwise set by RADIUS (defaults to 0, meaning unlimited).
acctupdate
Allow updating of session parameters with RADIUS attributes sent in Accounting-Response.
wwwdir path
Directory where embedded local web content is placed. This content is accessible using the URL format http://:/www/
wwwbin script
Executable to run as a CGI type program (like haserl) for URLs with extention .chi - in the format http://:/www/.chi
uamui script
An init.d style program to handle local content on the uamuiport web server.
uamanydns
Allow any DNS server. Normally unauthenticated clients are only allowed to communicate with the DNS servers specified by the dns1 and dns2 options. If the uamanydns option is given ChilliSpot will allow the client to use all DNS servers. This is convenient for clients which are configured to use a fixed set of DNS servers. For security reasons this option should be combined with a destination NAT firewall rule which forwards all DNS requests to a given DNS server.
dnsparanoia
Inspect DNS packets and drop responses with any non- A, CNAME, SOA, or MX records (to prevent dns tunnels; experimental).
uamanyip
Allow clients to use any IP settings they wish by spoofing ARP (experimental).
nouamsuccess
Do not return to UAM server on login success, just redirect to original URL.
nouamwispr
Do not do any WISPr XML, assume the back-end is doing this instead.
usestatusfile
Write the status of clients in a non-volatile state file (experimental).
chillixml
Return the so-called Chilli XML along with WISPr XML.
macauth
If this option is given ChilliSpot will try to authenticate all users based on their mac address alone. The User-Name sent to the radius server will consist of the MAC address and an optional suffix which is specified by the macsuffix option. If the macauth option is specified the macallowed option is ignored.
macallowed mac
List of MAC addresses for which MAC authentication will be performed. Example:

macallowed 00-0A-5E-AC-BE-51,00-30-1B-3C-32-E9

The User-Name sent to the radius server will consist of the MAC address and an optional suffix which is specified by the macsuffix option. If the macauth option is specified the macallowed option is ignored.

It is possible to specify the macallowed option several times. This is useful if many mac addresses has to be specified.

macsuffix suffix
Suffix to add to the MAC address in order to form the User-Name, which is sent to the radius server.
macpasswd password
Password used when performing MAC authentication. (default = password)
macallowlocal
An option to allow MAC authentication based on macallowed without the use of RADIUS authentication.
localusers file
A colon seperated file containing usernames and passwords of locally authenticated users.
postauthproxy ipaddress
Used with postauthproxyport to define a post authentication HTTP proxy server.
postauthproxyport port
Used with postauthproxy to define a post authentication HTTP proxy server.
locationname name
Human readable location name used in JSON interface.

FILES

/usr/local/etc/chilli.conf

The main chilli configuration file. Per default, this file includes three other files; main.conf, hs.conf, and local.conf. The main.conf and hs.conf are created by the shell script routines in functions based on configurations in the files mentioned below and possibility taking some configurations from a remote RADIUS server or URL. The local.conf file is reserved for location specific configurations.

/usr/local/etc/chilli/defaults

Default configurations used by the chilli init.d and functions scripts in creating the actual configuration files. See the comments in this file for more information on how to configure chilli and related scripts and embedded content.

/usr/local/etc/chilli/config

Location specific configurations used by chilli init.d and functions scripts. Copy the defaults file mentioned above and edit. This file is loaded after the defaults and thus will override settings.

/usr/local/etc/chilli/functions

Helps configure chilli by loading the above configurations, sets some defaults, and provides functions for writing main.conf, hs.conf, and local.conf based on local and possibily centralized settings.

/usr/local/etc/init.d/chilli

The init.d file for chilli which defaults to using the above configurations to build a set of configurations files in the /usr/local/etc/chilli directory - taking local configurations and optionally centralized configurations from RADIUS or a URL.
