This thread is now obsolete, check out this thread instead I figured out how to modify the NAS200 firmware (V3.4 R62) to run a telnetd daemon for shell access. See http://www.nslu2-linux.org/wiki/NAS200/Telnet to find out how I did it. You don't have to open the box so you won't void your warranty but you will need a Linux PC and some development tools such as Make to build the firmware. The only problem I had with installing my own firmware was that the Twonky server goes nuts: it completely ignores the settings in the NAS200 setup pages and the database goes kerploowy: my D-Link DSM-320RD UPnP media player only finds a 48x48 Twonky icon when I run my own firmware. So just for gits and shiggles I downloaded the Linux x86 version of TwonkyVision 4.4.3 (the latest) onto a harddisk of the NAS200, and used Telnet to start it from there. And guess what: it works! Even better: it works better than the TwonkyVision that was included in the original NAS200 firmware: now my DSM-320RD shows all my videos (encoded in MPEG-1 by my photo camera and MPEG-4 "simple" with Nero Recode 7, haven't tried MPEG-2 yet) and my photos (although it takes very long for photos to show: probably Twonky has to resize them which takes long). And of course the downloaded Twonky has all the configuration web pages that are missing on the NAS200. I can even stream Shoutcast radio to my UPnP player. Cool! Looks like after two years, I can finally put my dusty DSM-320RD to good use! I LOVE that NAS200 (and no, I don't work for Linksys or D-Link ) ===Jac I know I may have to buy a new license for TwonkyVision (since the one I'm using now is not the one that came with the NAS) but I think it's worth it.
