The pink/amber light issue occurs upon startup of the DNS-323 after installing Twonky 6. I believe the memory in the root filesystem file in the NAS is used up and that prevents the NAS from fully booting and it will not be accessible from the network [see http://forum.dsmg600.info/viewtopic.php?id=5688
]. To prevent it you need to edit the starttwonky.sh file [see http://forum.dsmg600.info/viewtopic.php?id=3726&p=1
1. Download the DNS-323 Twonky NAS installation package at downloads/6.0.1/twonkymedia-dns323-6.0.1.zip
2. Enable Telnet access on the NAS (already done in your case. http://wiki.dns323.info/howto:ffp
3. Run the DNS-323 Twonky NAS installer. Important - during installation uncheck the option box that will start the twonky server. If you forget to uncheck it, the server will start initiallizing after installation and you will get the pink/amber light issue.
4. Open the file starttwonky.sh in volume 1 of the NAS and change the contents to:
route add -net 18.104.22.168 netmask 240.0.0.0 dev egiga0
ln -s /mnt/HD_a2/.TwonkyMediaServer /home/root
/mnt/HD_a2/twonky/twonkymedia -appdata /mnt/HD_a2/twonkydata &
Save the file. If I remember correctly, the only change to the code is the addition of the -appdata line.
5. Log on to telnet and start Twonky Server (with command /mnt/HD_a2/starttwonky.sh)
6. If you experience the pink/amber light issue already or forget to uncheck the start server box during the installation, it gets a little tricky. Using a PC (could not get it to work with my mac) there is a brief period during the boot/startup of the DNS-323 where you can access the NAS over your network before the twonky server starts to load. At this point the drive lights will still be clue. Quickly access the NAS and change the filename of starttwonky.sh in Volume 1 to something else (oldstarttwonky.sh or whatever), which will prevent twonky from loading and buy you some time to make other changes. Then open that file and make the above changes to it. Save the file and name it back to starttwonky.sh. Restart the DNS and it should work again. Remember, if you wait until the drive lights are pink to try accessing the NAS, it will not be visible on your network so you need to act fast while the lights are still blue during the boot for all of this to work.
Hope this longwinded post helps.
