OpenWRT: Setup Coova-Chilli
OpenWRT+CoovaChilli
Introduction Today I am going to share my experience in Installing CoovaChilli on a router.
My first attempt with this endeavor ended up with me having a very expensive brick instead of a captive portal. So for those who want to avoid this costly experience I am laying out this simple installation process for you to follow and hopefully succeed. Once you get comfortable with it you can then venture into more riskier approach, like compiling your own OpenWRT.
I am using TP-Link's MR3220 as my router. Though I haven't tried it yet, I hope the same approach will work on other routers based on Altheros AR71xx. Let's start!
Download required Packages
1. Download openwrt-ar71xx-generic-tl-mr3220-v1-squashfs-factory.bin from http://downloads.openwrt.org/snapshots/trunk/ar71xx/.
2. Download the following from http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/
coova-chilli_1.2.9-1_ar71xx.ipk haserl_0.9.29-1_ar71xx.ipk kmod-tun_3.3.8-1_ar71xx.ipk libpthread_0.9.33.2-1_ar71xx.ipk librt_0.9.33.2-1_ar71xx.ipk
Flash OpenWRT for MR3220
Use a LAN cable to connect your computer to one of the LAN ports of the router Start a browser and go to http://192.168.1.1 (this is the router's default IP address, change this accordingly if you already changed your router's IP address) Choose System Tools --> Firmware Upgrade Click the Browse button Locate and select openwrt-ar71xx-generic-tl-mr3220-v1-squashfs-factory.bin file Click the Upgrade button Wait until it says rebooting
In this stage OpenWRT is already installed in your router and you will not be able to access your router’s web interface Initialize OpenWRT For first time login, you have to set root’s password. Follow these steps.
Still connected to your router, open telnet and connect to 192.168.1.1 Once logged in you should be see a display similar to this:
BusyBox v1.19.4 (2012-11-18 23:21:39 EST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

* 1/2 oz Galliano Pour all ingredients into

root@OpenWrt:~#
To set root’s password type passwd the press return key Type in root’s new password, press return, then re-type the password for confirmation
After setting the password you should quit telnet and login to the router using ssh Setup Wireless Configuration
Login to the router using ssh
ssh root@192.168.1.1 Edit /etc/config/wireless vi /etc/config/wireless Comment or delete the line “option disabled 1” to enable wireless LAN Optionally change the SSID by changing the value of “option ssid”, from OpenWRT to your choice Save and close the file Execute wifi to force the system to re-read the wireless configuration file and start wireless LAN
Install CoovaChilli
Go to your computer’s terminal and copy the rest of the packages to router’s /tmp directory scp coova-chilli_1.2.9-1_ar71xx.ipk haserl_0.9.29-1_ar71xx.ipk kmod-tun_3.3.8-1_ar71xx.ipk libpthread_0.9.33.2-1_ar71xx.ipk librt_0.9.33.2-1_ar71xx.ipk root@192.168.1.1:/tmp Log back in to the router ssh root@192.168.1.1 Go to /tmp and install the packages in the following order opkg install librt_0.9.33.2-1_ar71xx.ipk opkg install libpthread_0.9.33.2-1_ar71xx.ipk opkg install kmod-tun_3.3.8-1_ar71xx.ipk opkg install coova-chilli_1.2.9-1_ar71xx.ipk opkg install haserl_0.9.29-1_ar71xx.ipk
Setup CoovaChilli
Configuration File
Open /etc/chilli/defaults and change the following lines
from “# HS_WANIF=eth0 # WAN Interface toward the Internet”
to “HS_WANIF=eth1 # WAN Interface toward the Internet”
from “HS_LANIF=eth1 # Subscriber Interface for client devices”
to “HS_LANIF=wlan0 # Subscriber Interface for client devices”
from “HS_RADIUS=locahost”
to “HS_RADIUS=<your RADIUS IP address>”
from "HS_RADSECRET=testing123 # Set to be your RADIUS shared secret"
to "HS_RADSECRET=<your RADIUS password> # Set to be your RADIUS shared secret
Save and close the file
Start-up Script
Now we need to create the startup script for coova-chilli. Coova-chilli package does not provide this so we have to create this by hand
Create a the file /etc/init.d/chilli with the following content
#!/bin/sh /etc/rc.common
# - init script for chilli -
START=60
STOP=90
NAME=chilli
RUN_D=/var/run
CMDSOCK=$RUN_D/$NAME.sock
PIDFILE=$RUN_D/$NAME.pid
option_cb() { [ -n "$2" ] && echo "HS_$(echo $1|tr 'a-z' 'A-Z')=\"$2\"" | sed 's/\$/\\\$/g'; }
config_load hotspot > /etc/chilli/config
. /etc/chilli/functions
start() {
HS_DNS_DOMAIN=${HS_DNS_DOMAIN:-cap.coova.org}
HS_DNS1=${HS_DNS1:-$HS_UAMLISTEN}
HS_DNS2=${HS_DNS2:-$HS_NASIP}
HS_NASID=${HS_NASID:-$HS_NASMAC}
HS_MACAUTHMODE=${HS_MACAUTHMODE:-local}
HS_USELOCALUSERS=${HS_USELOCALUSERS:-off}
HS_PROXY_TYPE=${HS_PROXY_TYPE:-none}
HS_RADCONF_URL=${HS_RADCONF_URL:-http://ap.coova.org/config/tos.conf}
HS_CFRAME_URL=${HS_CFRAME_URL:-http://coova.org/cframe/default/}
HS_CFRAME_SZ=${HS_CFRAME_SZ:-100}
HS_DEFSESSIONTIMEOUT=${HS_DEFSESSIONTIMEOUT:-0}
HS_DEFIDLETIMEOUT=${HS_DEFIDLETIMEOUT:-0}
HS_DEFINTERIMINTERVAL=${HS_DEFINTERIMINTERVAL:-300}
HS_LAN_ACCESS=${HS_LAN_ACCESS:-deny}
HS_CFRAME_POS=${HS_CFRAME_POS:-top}
HS_PROVIDER=${HS_PROVIDER:-Coova}
HS_PROVIDER_LINK=${HS_PROVIDER_LINK:-http://coova.org/}
HS_LOC_NAME=${HS_LOC_NAME:-My HotSpot}
HS_LOC_NETWORK=${HS_LOC_NETWORK:-Coova}
HS_OPENIDAUTH=${HS_OPENIDAUTH:-off}
HS_ANYIP=${HS_ANYIP:-off}
[ -z "$HS_LANIF" ] && {
[ -e /tmp/device.hotspot ] && {
stop
}
HS_LANIF=$(wlanconfig ath create wlandev wifi0 wlanmode ap)
for i in 0 1 2 3 4; do ifconfig ath$i mtu 1500; done 2>/dev/null
echo $HS_LANIF > /tmp/device.hotspot
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iwconfig $HS_LANIF essid ${HS_SSID:-Coova} 2>/dev/null
}
writeconfig
radiusconfig
[ -d $RUN_D ] || mkdir -p $RUN_D
/sbin/insmod tun >&- 2>&-
/usr/sbin/chilli
}
stop() {
[ -f $PIDFILE ] && kill $(cat $PIDFILE)
rm -f $PIDFILE $LKFILE $CMDSOCK 2>/dev/null
iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
wlanconfig $(cat /tmp/device.hotspot) destroy
rm /tmp/device.hotspot
}
Automatically Start CoovaChilli
Create a symbolic link to /etc/init.d/chilli in /etc/rc.d and name it S60chilli
cd /etc/rc.d ln -s ../init.d/chilli S60chilli
This will automatically start CoovaChilli everytime you start your router.
Login Page Lastly we need to create the login pages for CoovaChilli. CoovaChilli's package for OpenWRT does not include this and so we have to download CoovaChilli's source code and copy the contents of the miniportal forder
Back in your computer, download CoovaChilli's source code wget http://ap.coova.org/chilli/coova-chilli-1.2.9.tar.gz Untar the package tar -xzvf coova-chilli-1.2.9.tar.gz Goto the miniportal folder cd coova-chilli-1.2.9/miniportal Edit the files functions.sh.in, config-local.sh.in, uam.sh.in and replace @SBINDIR@ and @ETCCHILLI@ with /usr/sbin and /etc/chilli respectively Rename the files that end in ".in", removing ".in" part e.g. functions.sh.in will be renamed to functions.sh
Copy the contents of miniportal folder to your router's /etc/chilli/www scp * root@192.168.1.1:/etc/chilli/www/
We're done. All you have to do is reboot your router and connect to it once it starts up.
When you open your browser and starts browsing you will be redirected to CoovaChilli's login page.
Enjoy!!!
