I have installed the Darwin streaming server, for QuickTime streaming. But, I don´t know how to open ports 7070 or 554 for UDP or RTSP. I can´t use HTTP port 80 because it´s in use by the Apache web server. I can´t also run the QuickTime Proxy. Both packages are available form Apple Computer Open Source Web site.
Could I change the /etc/services file to make these changes?
