How to set up Linksys as a RIP2 router with client mode

How to set up Linksys as a RIP2 router with client mode

1. Load Alchemy pre-release 5.2.3 onto the linksys

2. Set the Linksys Wireless interface to Client mode and set SSID to "pta-mesh"

Using the web interface select Wireless - Basic Settings
Wireless Mode : Client
SSID: pta-mesh
Select Save Settings - continue

3. Choose your IP addresses for the Wireless interface and the LAN interface

I chose the following
WAN interface: 10.50.1.13
LAN interface: 10.3.11.1

Using the Web interface select Setup - Basic Setup
Internet Connection Type: Static IP
Internet IP Address: 10.50.1.13
Subnet Mask: 255.255.255.0
Router Name: Something you like eg. david_home
Local IP Address: 10.3.11.1
Subnet Mask: 255.255.255.0

Select Save Settings - continue

4. Add router configuration files to the target directory

Enter the router directory ($LINKSYS/src/router)
# cd /mipsel-uclibc/target
# mkdir /usr/local
# mkdir /usr/local/etc

Download my RIP configuration files for linksys
ripd.conf
zebra.conf

Copy these files to $LINKSYS/src/router/mipsel-uclibc/target/usr/local/etc

Download my image making script which will build files in the code.bin image
makeimage.sh

Copy this script to $LINKSYS/src/router
Run the script
./makeimage.sh

You should now have a code.bin with the router config files in /usr/local/etc
Upload this new firmware to the linksys

5. Add commands to rc_startup to startup RIP, Flush iptables (so that RIP messages can arrive on RIP port) and remove NAT

zebra -d -f /usr/local/etc/zebra.conf
ripd -d -f /usr/local/etc/ripd.conf
iptables -F
iptables -F -t nat

8. You should now have a rip enabled linksys client - Try ping the network connected to the wireless interface from a machine connected to the LAN


Things to improve in this recipe
1. Don't flush all iptables - just enable the port for RIP routing
2. Find location in Makefile where the code.bin image is made - don't need my custom script

Compiling Satori 4.0 with latest tool chain

To compile using the latest toolchain:

1) Apply this patch (also fixes zebra):
http://www.greyskydesigns.com/~lonewolf/satori_fix.patch

Code:
lonewolf@lonewolf:/data4/wrt54g/satori/WRT54G$ patch -p1 --dry-run
patching file src/router/rc/writeimage.c
patching file src/router/zebra/Makefile
patching file src/router/zebra/lib/Makefile
patching file src/router/zebra/ospfd/Makefile
patching file src/router/zebra/ripd/Makefile
patching file src/router/zebra/zebra/Makefile
lonewolf@lonewolf:/data4/wrt54g/satori/WRT54G$ patch -p1
patching file src/router/rc/writeimage.c
patching file src/router/zebra/Makefile
patching file src/router/zebra/lib/Makefile
patching file src/router/zebra/ospfd/Makefile
patching file src/router/zebra/ripd/Makefile
patching file src/router/zebra/zebra/Makefile
lonewolf@lonewolf:/data4/wrt54g/satori/WRT54G.orig$


2) Run 'make'

3) When 'make' errors out, run 'for i in src/router/iproute2/lib/*.a; do mipsel-uclibc-ranlib $i; done'

4) Run make again

5) for i in src/router/iproute2/tc/*.a; do mipsel-uclibc-ranlib $i; done

6) make yet again

How to route between WLAN and LAN on the linksys box

Make sure you have installed Sveasoft Alchemy 5.2.4

Go to Administration - Diagnostics and enter the following into the command line
brctl delif br0 eth1
ifconfig eth1 down
ifconfig eth1 up
if addr add 192.168.2.1/24 dev eth1

Click on "save startup"
Reboot linksys

This will create a new subnet for the wireless side of the router on the 192.168.2.0 network
The LAN side of the router will remain on the 192.168.1.0 network
