Resources for “Linux on Linksys Wi-Fi Routers”

Seattle Wireless is one of the largest wireless networking communities and maintains a large Web site with up-to-date Wi-Fi information:

Linksys Source Code (Linksys, now a division of Cisco Systems, has a support section with GPL source code for its products):

The WRT54G Group maintains a mailing list and an on-line support group and is an active discussion forum for the WRT54G:

Sveasoft, this Swedish company's site is the author's home on the Net and his personal favorite. The Linksys forum is focused primarily on the Linksys WRT54G and offers source code and firmware downloads:

Broadband Reports—this on-line forum has several active discussion groups focused on the major wireless device manufacturers. The Linksys forum is a great source of information and tips:,16.

OpenWRT is a recent project that promises to offer a hacker's version of the WRT54G source code. At the time of this writing nothing is available, but it's still worth a peek:

Another cool alternative is

There's also a security distribution (built on top of OpenWrt) that adds WPA Enterprise wireless, IDS, IPS, and remote access VPN functionality to your wifi router-

I built firmware version 2.04.3 from source and transfered the image to a WRT54G v2 router, without converting it into a doorstop. The instructions in the article didn't quite match the contents of the source code I downloaded from Linksys, so in case it's useful for someone else, these are the steps I took:

  • tar xzf wrt54g.2.04.3.tgz
  • su -c 'ln -s $PWD/WRT54G/tools/brcm /opt'
  • PATH=$PATH:/opt/brcm/hndtools-mipsel-linux/bin:/opt/brcm/hndtools-mipsel-uclibc/bin
  • cd WRT54G/release/src/router
  • make menuconfig
  • cd ..
  • make

This process builds the file WRT54G/release/image/code.bin which I transfered to the router using the web interface.

Now on to the interesting stuff!

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
