In my case I needed to kill the ant/java processes running the server after the java modules were initially retrieved and the server built for the first time, but the second time it was fine even though it did take about 30 seconds to fully startup - this may just be a glitch on my system as I have a lot of other stuff also going on. The final step is to test it. This can be done by moving the contents of the webapps/root/demos/ folder from the extracted Red5 directory to a webserver somewhere (I don't think it hast to be the same machine) and then viewing the list of demos in the index.html file.I started off by using the port tester to make sure the demo apps could actually connect to the server on the ports they were meant to (basically rtmp port 1935) and then moved onto testing the video streaming app and then tried a proper live broadcast through the server using the simpleBroadcaster app to two friends who were logged on using the simple subscriber app. All worked well especially as far as the video was concerned though the audio was a little crackly on my live broadcast - this could just be the quality of home connections however.The only last not is just a simple reminder that when running the test apps you'll need to specify the server they need to connect to - the apps are setup to access rtmp://localhost/[APP_NAME] but if you're not running these apps as a local user you will need to change localhost to the name or ip of the server Red5 is installed on So far I'm quite happy with Red5 as a free (very important) alternative to FMS2, but should you be looking for a commercial product as this is not quite up your street (that is a cheaper than FMS2), then take a look at this instead: [http://www.wowzamedia.com/index.html](http://www.wowzamedia.com/index.html) Wowza only requires java to run and is like a very polished commercial version of the Red5 server (it was actually through installing Wowza that I worked out what to do with the web apps for Red5 - having had no previous experience in flash streaming other than literally installing FMS2) which has a very reasonable price tag in comparison to the cost of FMS2
