dlna server on Raspberry Pi

This is too easy!

Just do:

# apt-get install minidlna

And then edit /etc/minidlna.conf. Look for the line:

media_dir=

(probably line 26)

And write there the directory of your choice. Then:

# /etc/init.d/minidlna force-reload

And it should work (if you have a dlna client, of course). In my case, I have a Samsung TV with a RJ45 interface, capable of discovering DLNA servers on the network.

You can also have different directories for Music, Movies and Pictures, I recommend to read the manual of minidlna.conf:

$ man minidlna.conf

I have to say that the performance of RPi so far is quite good, I am watching a video perfectly while compiling Quake3 (my next task).
