Openwrt
Openwrt knowledge
NVRAM
NVRAM is the EEPROM of the wrt54g. The Settings stored in the NVRAM is used by openwrt to configure the network interfaces and other settings like timezone and so on.
OLSR
OLSR means Optimized Link State Routing protocol.
OLSR is a routing protocol for mobile ad-hoc networks. The protocol is pro-active, table driven and utilizes a technique called multipoint relaying for message flooding. You can configure multiple openwrt routers to talk to each other to find the best route from point A to point B.
WDS
WDS (Wireless Distribution System) can be used to mae a special tunnel between two openwrt's. It is also supported by many other Accesspoints. I didn't bring it to work so i had been looking for another solution. MESH networks soltuions can do that. OLSR is one implementation for that. AODV is another one.
Installing the software
Installing the openwrt firmware
I use this script to takeover the wrt54g. Get your firmware and copy it to the same directory as the takeover script.
Whether to use jffs2 or sqashfs is a philosophical question.
Plug in your wrt54g to you linux box. Configure your box in side 192.168.1.0/24 (not 192.168.1.1!)
| Code: Installing openwrt on the Linksys wrt54g |
wget http://downloads.openwrt.org/whiterussian/rc2/bin/openwrt-wrt54g-jffs2.bin wget https://aachen.uni-dsl.de/download/wrt/Snapshots/rev121/buildroot-rev121/takeover chmod +x takeover cp openwrt-wrt54g-jffs2.bin openwrt-g-code.bin ./takeover |
Wait about 5 minutes. If openwrt is booting the DMZ LED should lightning.
