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

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)
