hi thomas, thank you for your reply. here are my doubts, 1. what is sample rate and is there any relation between bitrate and sample rate. 2. how can i see data log for streams on icecast server - i want to see if there is any spikes in users on particular mountpoint, so that i can configure that stream on a dedicated server with high bandwidth. 3. are there any security measures i should take to protect from hackers. 4. i want to see any configuration recommendations in icecast documentation. 5. i can share my documentation if you are interested to write an article on how-to-setup basic icecast server to stream live feed.

Anyway, on to the items.> 1. what is sample rate and is there any relation between bitrate and > sample rate. >That's more of a fundamental question. I'd recommend to read about the basics of digital audio and codecs. That is certainly going to answer any questions in this regard. You could start here: http://en.wikipedia.org/wiki/Digital_audio and here: http://en.wikipedia.org/wiki/Audio_codec and follow to other articles or better resources. A university library should also have books that cover digital signal processing. In brief: with lossy codecs there is a loose relationship between sample rate and bit rate.> 1. how can i see data log for streams on icecast server - i want to > see if there is any spikes in users on particular mountpoint, so > that i can configure that stream on a dedicated server with high > bandwidth. >Icecast follows the Unix principle of focusing on one thing and getting it right. This means that while we do produce all the necessary raw data for this it is not necessarily easy to grasp by looking at it. There are however other tools that are good at specifically processing logs or status data. In the question at hand you can resort to either log analysis - most server log software supports icecast; or you can use real time sampling - there are plug-ins for Munin and Cacti at least. e.g. http://www.ruecker.fi/foss/icecast/munin-icecast-0.1.tar.bz2> 1. are there any security measures i should take to protect from hackers. >- Chose secure passwords that can't be brute-forced - use separate passwords for every user, if necessary use a secured url-auth backend. - preferably use SSL for connections that need to authenticate or secure them otherwise (local, vpn, tunnels, etc.)> 1. i want to see any configuration recommendations in icecast > documentation. >The documentation provides examples that can be easily customized to each individual use case.

Hello !! I use Icecast (version 2.3.3-1) on Debian GNU/Linux. The same listener can connect to the Icecast server many times as desired and maintain such connections active for an indefinite time, even using the same PC and the same web browser. This can be seen listening to this radio station (HTML5) http://186.148.147.191:8001/zuzenean.ogg and looking for some statistics here (updated every 30 seconds) http://186.148.147.191/nor/nor.php Thinking that many servers have a not too wide Internet bandwidth, can be implemented in the Icecast configuration any option that would limit the number of simultaneous connections to the same listener ?. Of course, there may be more of one listener behind a single IP and also such listeners may be using the same operating system and the same web browser. So, how differentiate them ?. If the server does not know the MAC address numbers for each listener, can be achieved with PHP ($ _SERVER ['REMOTE_PORT'], $ _SERVER ['REMOTE_USER'], etc.) to differentiate them ?. Maybe this is already covered by a newer Icecast version. Jos? Luis

[Icecast] Simultaneous connections (same listener)

Through an URL auth backend you are free to enforce self defined rules on client connections. http://icecast.org/docs/icecast-2.3.3/icecast2_listenerauth.html Cheers Thomas
