PREPARE DEVELOPMENT ENVIRONMENT

1. Check out sources

Check out meraka trunk
Check out: OpenWRT Kamikaze

 $ cd ~
 $ svn checkout https://svn.openwrt.org/openwrt/trunk/ kamikaze/
 $ cd kamikaze/
 $ ./scripts/feeds update -a                 # Checkout the extra packages
 $ ./scripts/feeds install <name_1> <name_2> # Creates the symlinks for the packages you like to install
 $ make menuconfig                           # Select your target, packages and other options. Only select the packages you need.
 $ make world

Link to existing OpenWRT
Check out SVN version of coova-chilli

2. Configure OpenWRT

Read:

 http://wiki.openwrt.org/OpenWrtDocs/Packages

Get some stuff from source:

 cd package ; svn co http://dev.coova.org/svn/coova-ap/packages/kamikaze/coova-chilli ; cd ..

Run:

 ./scripts/feeds install libnetsnmp

Select packages:

 Base->pthread
 Administration->meraka-widgets
 libnetsnmp
 coova-chilli
 ./scripts/feeds install batmand
 ./scripts/feeds install batmand-adv

Edit: package/opkg/files/opkg.conf

 src packages http://l-cube.artifactual.org.za/~antoine/firmware/packages/mipsel

3. Build Everything

Run:

 make

INSTALLATION AND CONFIGURATION FOR LINKSYS WRT54G(L)

0. prepare router

Handy:

 nvram set boot_wait=on
 nvram commit
 wget http://l-cube.artifactual.org.za/~antoine/firmware/openwrt-brcm-2.4-squashfs.trx -O - | mtd -e linux -r write - linux
 opkg update
 opkg install snmpd ; ln -s ../init.d/snmpd S70snmpd

1. flash router

Run:

 wget http://l-cube.artifactual.org.za/~antoine/firmware/openwrt-brcm-2.4-squashfs.trx -O - | mtd -e linux -r write - linux

2.a. configure portal interface (when using wireless port for dev - DEPRECATE)

 uci delete network.lan.type
 uci set wireless.cfg03c014.network=wifi

Append: /etc/config/network

 config 'interface' 'wifi'
         option 'ifname' 'wl0'

Run:

 uci set dhcp.lan.ignore=1
 uci set wireless.wl0.disabled=0 
 uci set network.wifi.ifname=wl0
 uci set network.wifi.proto=static
 uci set network.wifi.ipaddr=0.0.0.0
 uci commit
 reboot

Test:

 echo 1 > /proc/sys/net/ipv4/ip_forward
 iptables -I POSTROUTING -t nat -o eth0.0 -j MASQUERADE

Append: TODO

 echo "echo 1 > /proc/sys/net/ipv4/ip_forward" >> ???
 echo "iptables -I POSTROUTING -t nat -o eth0.0 -j MASQUERADE" >> ???

2.b. Configure router for B.A.T.M.A.N. (using lan port for dev)

Run: (configure LAN interface)

 uci delete network.lan.type
 uci delete network.lan.gateway
 uci delete network.lan.dns
 uci set network.lan.ipaddr=192.168.1.1
 uci commit

Run: (temmporarily disable firewall so we can get in to the WAN interface from my own lan side)

 iptables --flush

Run: (OPTIONAL: configure WAN interface for a gateway mesh-node)

 uci set network.wan.proto=static
 uci set network.wan.ipaddr=192.168.20.200
 uci set network.wan.netmask=255.255.255.0
 uci set network.wan.dns=192.168.20.5
 uci set network.wan.gateway=192.168.20.1

 uci set network.wifi=interface
 uci set network.wifi.ifname=wl0
 uci set wireless.wl0.disabled=0
 uci set wireless.wl0.channel=5
 uci set wireless.cfg03c014.network=wifi
 uci set wireless.cfg03c014.mode=adhoc              # TODO - wtf is it with the numbers ?
 uci set wireless.cfg03c014.ssid=batman
 uci commit 
 reboot

4a. configure flatfile authentication (freeradius - running on dashboard server -> ubuntu JEOS)

Read:

 http://wiki.freeradius.org/index.php/FreeRADIUS_Wiki:FAQ#How_do_I_get_radius_to_pick_up_changes_in_the_raddb.2Fusers_file.3F

Run:

 apt-get install freeradius

Edit: /etc/freeradius/radiusd.conf:113

 pidfile = /var/run/freeradius/freeradius.pid

Edit: /etc/freeradius/clients.conf

 client 192.168.20.0/24 {
   secret     = theradiussecret
   shortname  = meshportal
   #nastype    = other
 }

Edit: /etc/freeradius/users

 $INCLUDE users.chilli
 DEFAULT Auth-Type := Reject
         Reply-Message = "Login attempt failed.",
         Fall-Through = No

Create: /etc/freeradius/users.chilli

 chillispot     ClearText-Password := "thechillispotsecret"
 joe            ClearText-Password := "smith"
 guest          ClearText-Password := "guest"
                Session-Timeout = 300,
                Idle-Timeout = 60,
                WISPr-Bandwidth-Max-Up = 64000,

                Reply-Message := "%{Session-Timeout} left %{User-Name}."

Test:

 radtest chillispot chillispot 192.168.20.225 10 theradiussecret
 /etc/init.d/freeradius start
 kill -1 `cat /var/run/freeradius/freeradius.pid`

Edit: /etc/group (Permissions)

 freerad:x:124:www-data

Run: (Permissions)

 chmod -R g+w /etc/freeradius

Run:

 copy over our custom radius users files&dir

4b. configure mysql authentication (freeradius - running on dashboard server -> ubuntu JEOS)

Install:

 apt-get install libmysqlclient-dev

Edit: /etc/freeradius/users (disable flat file user entries)

 . comment out users.chilli include and DEFAULT rule

Edit: /etc/freeradius/sql.conf

 database = "mysql"
 server = "localhost"
 login = "radius"
 password = "radpass"
 radius_db = "radius"

Edit: /etc/freeradius/sites-enabled/default

 authorize:152 -> sql
 accounting:344 -> sql
 session:369 -> sql
 post-auth:396 -> sql

Edit: village-bus-radius/Makefile

 .set correct mysql username and password

Run: (create radius tables for mysql)

 make mysql

Run: (populate radius tables for mysql with defaults & test data)

 make mysql-populate

5. install meraka-*

  make package/meraka-widgets-compile V=99
  make package/index
  # scp ./build_dir/mipsel/meraka-widgets-0.1/village-bus-* root@192.168.20.200:/www/cgi-bin/
 opkg remove meraka-widgets  
 opkg install http://l-cube.artifactual.org.za/~antoine/firmware/packages/mipsel/meraka-widgets_0.1-1_mipsel.ipk
