I've been trying to get any upnp media server to work on a nslu2 with openwrt (2.6.21.6 #2 arm5teb ).  I've tried miniupnp but even though it showed in ps -aux as running, I couldn't see it from any client. Then I tried gmediaserver thinking it would be more robust, but the init.d script errors out with invalid address  or interface name 'br-lan'.  My ifconfig only shows eth0 and lo.  I'm guessing br-lan is more for routers, this is just the nslu2.

Any recommedations? thanks in advance. If I can't get miniupnp or gmediaserver I guess the next step would try something like twonky.

Sorry to reply to my post, but I wanted to add more info. I just tried mediatomb and ram out of space with one lib to go so that isn't working either.
