Hacking the Linksys WMLS11B

This isn't specific to Linux, the WMLS11B is a Wireless Music Player. I happen to use it on Linux based Media Servers. I also plan to get 2 more of these units for around the house.

Trust me when I say there is a lot of information on this little device. I just have to get on this page. I hope to add a few hack of my own such as changing some of the builtin URLs to point to a local machine instead of an Internet machine.

In the Yahoo Tech group, wmls11b library exists a file that, when compiled checks the checksum for the firmware. One possible hack is to edit the firmware with a binary editor, change the URLs to something local and serve up the various files that the WMLS11B needs from a local server. I still need to do a lot of work on figuring out what the WMLS11B is doing but a good sniffer and I'll be able to figure out what it's doing.
