- Introduction:
-
- SHOUTcast is a streaming audio system for Windows and Un*x platforms.
- The SHOUTcast server is the core of the system, and includes unique
- features which distinguish SHOUTcast from other servers, including the
- ability to relay a common stream across multiple SHOUTcast servers to
- distribute load, and automatic integration into the SHOUTcast directory
- at http://yp.shoutcast.com for effective exposure of your SHOUTcast
- server to the world at large, when desired.
-
- SHOUTcast is a product of Nullsoft, Inc, makers of the fantastically
- popular Winamp audio player for Win32. The SHOUTcast system relies on
- Winamp for playback and content sourcing. Winamp is available at
- http://www.winamp.com
-
- Updates:
-
- SHOUTcast world headquarters is at http://www.shoutcast.com. Stop by
- to snag the latest version and view online documentation (with pictures,
- no less.)
-
- Bug reporting:
-
- SHOUTcast is freeware, and doesn't really have a support team to back it
- up. If you come up with an intelligent question or notice a glaring bug,
- please notify us at bugfixes@shoutcast.com, but be advised we cannot
- guarantee we'll be able to get back to you.
-
- Installation:
-
- Windows: Unzip into an appropriate location on your drive, i.e. c:\shoutcast.
- Make sure you have three files: sc_serv.exe, sc_serv.ini, and readme.txt.
-
- Unix versions: Use gunzip and tar to decompress and extract the necessary
- binaries for your particular operating system. When complete, you should
- have three files: the server binary, server config file, and this readme.
- Make certain the server is chmod u+x, and that the config file is readable
- by the user you want to run the server as. The server does *not* need to
- be run as root, unless you want to use port numbers below 1024 to serve
- SHOUTcast audio streams.
-
- Configuration:
-
- Windows: Edit the sc_serv.ini file in Notepad or click the Edit Config menu
- item in the server. The parameters should be self-explanatory. Remember
- to quit and restart your server (if it's running) to cause the changes to take
- effect.
-
- Unix: Edit the sc_serv.conf file in the text editor of your choice. Tom
- would prefer you use Emacs, because it makes Justin really mad. Justin would
- prefer you use vi, because he thinks Tom suffers from some vicious malaise.
- You'll probably be lame and end up using Pico.
-
- Tech Notes / How it Works:
-
- Without going into too much detail, the SHOUTcast server is an intelligent
- repeater. It receives data from a source, notifies the SHOUTcast directory
- when requested to by the client, and repeats the data from the source to
- the listeners. It attempts to do this rather efficiently.
-
- The Windows server runs under any 32 bit Windows O/S (NT, 95, 98). It's
- a threaded, multi-processor aware application. It uses about 2MB of RAM
- and very little CPU.
-
- The Unix server runs (as of this beta release) on win32, FreeBSD,
- Linux (libc5 and glibc), and Solaris.
-
- Remote Administration:
-
- Remote admistration is now far superior than SHOUTcast 1.0. Simply point
- your web browser to http://my.machine.ip:port/ and start from there.
- The classic LOG <password> and TAILLOG <password> commands still work via
- telnet, but using the web interface is preferable if you ask us :)
-
- A Word To The Unwise:
-
- All listeners are only able to listen at what their connections can support.
- For most users on the net, when you consider modem/PPP overhead, internet
- congestion, and the fact that most modems out there are around 33.6kbps, it
- makes sense to use 24kbps for most public streaming. Even though,
- theoretically, 33.6 users should be able to listen at 32kbps, with overhead
- it becomes impossible.
-
- Anyone with a 56k modem sending to an upstream server is affected by the
- asymmetric nature of 56k modems. That is, the fastest a 56k modem can download
- data as fast as 53kbps, the upload data is at most 31.2kbps. Sorry, no
- 56 or 32kbps streams are servable over a 56k modem.
-
- You cannot serve more users that you have available bandwidth. If you're
- running the SHOUTcast server over a modem link at any speed, the most you
- can muster is one user at 24 or 32kbps. Attempting to serve more users than
- you have bandwidth only causes skippage.
-
- Shell sysadmins will be *very* unhappy if you consume their available
- bandwidth and server CPU without their consent. SHOUTcast is a highly
- demanding program of bandwidth. A T1 line can only theoretically support
- about 60 listeners if no other traffic is on that T1. Additionally, each
- listener takes up a thread on the server operating system, which can slow
- some operating systems if allowed to expand beyond the limits of the system.
- If you throw up a SHOUTcast server unbeknownst to the sysadmin with 50+
- maximum users, you had better be prepared to face the consequences of your
- actions. As a fellow sysadmin, I offer this to you as your ONLY WARNING.
-
- Pick a smart number of maxusers for your server. Calculate by taking the
- available bandwidth you have, multiplying by 0.9 to account for overhead,
- and dividing by the bitrate you want to serve at. For example, an ADSL
- connection @ 768kbps upstream * 0.9 / 24kbps ~= 29 maximum users. Again,
- set this number too high, and when you reach the limit of bandwidth ALL
- the streams will start to skip.
