Can anyone recommend their favorite Ubuntu-based network management tools? I'm particularly interested in helping to manage public WiFi networks, eg. open-mesh networks with mini-routers <a href="http://www.open-mesh.com/store/" target="_blank">devices like this</a> one? Thanks,    Brian Footnote: At MIT this weekend, there will be a demo of <a href="http://people.zoy.org/%7Ewalken/wgt634u/HOWTO.html" target="_blank">Debian running on WGT</a>. Getting entire operating environments running on small RF devices is cool hackery - maybeUbuntu will find a way onto these devices. (Ubuntu 8.04 includes <a href="https://blueprints.launchpad.net/%7Eubuntu-mobile">release plans for Mobile and Embedded</a> systems - so maybe a promising step in this direction. ) On Sunday, 4/6 there is a session on <a href="http://bostonskillshare.org/workshop.php" target="_blank">Free (the) Net : Build Your Own Wireless Internet Router</a> - with an 11 AM demonstration of how to build a wireless access point to share internet services. They will also demo <a href="http://www.kismetwireless.net/" target="_blank">Kismet</a>, the "802.11 layer2 wireless network detector, sniffer, and intrusion detection system".
