Thanks Fizze, will use this ongoing – managed to get it all working last night. Turned of UPnp on the NSLU and now the web interface works all the time. When you have no knowledge of Linux commands a lot of this stuff is hard.
When I was trying to get it to work, I used the following command
chmod 777 /share/hdd/data/public/mp3
what does it do, and should i change it to something else more secure?
