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:

     Enter 'help' for a list of built-in commands.

     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!!!
