*sekali-sekali ngasih ikan :D* ps: belum dicoba, kalo sukses bilang ya ... http://www.rsmas.miami.edu/~angel/web/icecast.html # Relaying The idea behind relaying is that one server is limited by the bandwidth of his network connection. So even though I might have a 10 mbit connection to the internet, I still can't take in as many listeners as I want. Not to mention that the network administrators will nuke my swedish arse if they found out :) But, and this is where relays come in, if one of the connected listeners could send the stream to say 10 other listeners closer to him, then a lot more people would be able to enjoy my music. In the perfect world, you would have a treelike structure of relays distributing your stream all over the world. This is where you need a lot of friends with lots of bandwidth to waste ;) There are three types of relays in the icecast server. Pushing, pulling, and aliased relays (aka on demand relays) To make a long story short, a pushing relay is where an admin on the originating server connects one of the local streams to a remote server. A pulling relay is basicly the same, except that the request is sent from the remote server, which mounts a remote stream as a local stream. An aliased relay is special, and a very nice thing indeed. For those of you familiar with mount and automount in the unix environment, this is quite similar. Instead of keeping a remote stream on your server all the time, and wasting bandwidth when no one is listening, you add an alias on your server for a stream on a remote server. And when a client requests this stream on your server, then you connect and send him the stream. 1. Pulling relays The admin on a remote server (aka slave server) issues the 'relay pull' command and the icecast server will connect to the originating (master) server as a client and then mount the stream as a local source. This has the advantage that you don't have to share any passwords. 2. Pushing relays Pushing relays is where the admin on the master server issues the 'relay push' command and the icecast server connects to the remote (slave) server as a source. 3. Relaying using aliases Aliases for remote streams are added with the 'alias add' command or using the alias parameter in the icecast.conf file. When a client requests a stream which is an alias refering to a remote stream, the icecast server will connect to this remote server and mount this stream in as a local source, just like a relay pull. When no clients are longer listening to this stream, the server will kill this source, to save bandwidth. Prior to the 1.3.8 release, the requested stream URL had to match the alias exactly, using the server_name as the host part of the URL. For instance, if you added: alias add /cool http://cool.co:8000/cool, then if a user requested http://your.server.name:8000/cool then it would work fine, but if he requested http://localhost:8000/cool or http://your:8000/cool or perhaps the ip, it wouldn't work at all. Starting with 1.3.8, you can specify the keyword 'whatever' as host, and thus match all hosts in the request, like so: alias add http://whatever:8000/cool http://cool.co:8000/cool. 4. Proxy You can setup your icecast server as a proxy, which means that all requests for streams on remote hosts will make the icecast server mount the remote streams as local sources, just like aliases. Proxy mode is just like adding an alias for each and every audiocast in the world. Please note that it is very important that the server_name variable is correctly set if you want to run a proxy. -- FAQ milis di http://wiki.linux.or.id/FAQ_milis_tanya-jawab Unsubscribe: kirim email ke tanya-jawab-unsubscr...@linux.or.id Arsip dan info milis selengkapnya di http://linux.or.id/milis
