I just flashed the firmware in my Linksys WRT54G Wireless-G Router with a hacked version from Sveasoft. It adds a lot of features the factory firmware does not provide, like the ability to telnet into the router and install other applications. The next thing I want to do to the router is install Snort so that I can have some level of intrusion detection and alerting inside the access point. I got the original idea from Kevin Rose’s segment on The ScreenSavers
