Building a Wireless Network with Linux
I found out you also can easily build a wireless bridge, and thus not have to use routing to allow a wireless connection to connect to the rest of a LAN. Using a spare laptop, I first recompiled Linux to enable bridging. I then installed an eth0 interface with an assigned IP address to connect to the LAN. Next, I installed the Aviator card as eth1 without an assigned interface, then brought up both interfaces in promiscuous mode with
/sbin/ifconfig eth0 promisc up /sbin/ifconfig eth1 promisc up
Next, I downloaded Alan Cox's brcfg utility, and enabled bridging with
./brcfg -enaAfter starting a wireless connection, I could then access any computer on the LAN from the wireless laptop.
Wireless networking may not be the best solution if you need high-speed communication on or between your LANs, but the combination of Linux and a legacy laptop shows that you can build a useful and flexible wireless network at low cost. This is just one of the reasons I use Linux (besides being able to surf the Web while drinking a pool-side Margarita—with salt, on the rocks, thank you).
