Hello All, I'm trying to understand how the client/server interacts with ports and firewalls by exploring a non-essential application on my home network. The boxes are running FC4 and are connected to a router behind a DSL modem. The application is slimserver which streams mp3 files over a network to a piece of hardware called a Squeezebox Network Music Player, which I don't have. It can also steam the same files over the Internet to an mp3 player like xmms running anywhere on the network, which is how I want to use it. The documentation says that slimserver (which I have installed on one machine) must be reachable via port 9000. I program the slimserver playlist (which can include Internet radio) at http://localhost:9000. The clients (xmms) access the stream at http://localhost:9000/stream.mp3, where "localhost" is now the name of the box where slimserver is running. So far I can play music on the server machine but not remotely. What place(s) must I open port 9000? The router? Each of the client machines? How safe is this -- or rather, maybe I should ask, what precautions are advisable? Thanks for the help. I hope my language isn't too awkward. Doing seems to be the only way to really learn this stuff. Jerry
