Hi, thanks for the Darwin tutorial. Installation went smoothly and I am able to log in to administer the Darwin streaming server. According to the instructions: You can now test your install by opening QuickTime on a client (either Windows or the Mac) and using one of the sample files installed by Darwin. File > Open URL and type rtsp://yourip/sample_300kbit.mov What is meant by "yourip" in the above example url? I assume the author means the Darwin server IP, but no matter what IP or domain I use, the same result is: Unable to open 'rtsp://220.127.116.11/sample_300kbit.mov'
