- #### Aims In this section I'm going to walk you through the procedure of setting up an Iceccast server and then sending a live stream to it with IDJC. In addition I will demonstrate the connection of a listener to show that everything really does work. The advice below is for demonstration purposes only. Not covered are best practices of locking down an Icecast server for serious use. For that and other non IDJC related matters there are the Icecast forums and the Icecast documentation itself. #### Setting up Icecast ##### Why local? Everything in this tutorial will be demonstrated on the same machine and while not as impressive as sending a stream half way across your house, by making this tutorial single machine specific I can not only leave multi-machine as an exercise to the reader but also not have to worry about anyone's local network specifics or how many machines they have reasonable access to. ##### Installing Icecast Ubuntu
      sudo apt-get install icecast2
- Debian
      sudo -c "apt-get install icecast2"
##### The configuration file Take a look in your /etc/icecast2/ directory and you should find a file called icecast.xml. This file is and will be referred to as the Icecast server configuration file. In it are the settings for the various different Icecast options. Here below are the typical contents.
    <icecast>
        <limits>
            <clients>100</clients>
            <sources>2</sources>

            <source-timeout>10</source-timeout>
            <!-- If enabled, this will provide a burst of data when a client
                 first connects, thereby significantly reducing the startup
                 time for listeners that do substantial buffering. However,
                 it also significantly increases latency between the source
                 client and listening client.  For low-latency setups, you
                 might want to disable this. -->
            <burst-on-connect>1</burst-on-connect>
            <!-- same as burst-on-connect, but this allows for being more
                 specific on how much to burst. Most people won't need to
                 change from the default 64k. Applies to all mountpoints  -->

What we should do now is copy and paste this file into a text editor or start editing a copy of your original file. Hint: use your own file in preference to mine. Launch a text editor like gedit to do this. Next, select Save As in the text editor's menu, choose the file name icecast.xml, and save it in your home directory. ##### Attempting to run
    $ icecast2 -c icecast.xml
    FATAL: could not open error logging (/var/log/icecast2/error.log): No such file or directory
    FATAL: could not open access logging (/var/log/icecast2/access.log): No such file or directory
    FATAL: Could not start logging
Fix this by editing icecast.xml and change the logdir setting to /tmp which will solve the problem of inadequate write permissions and try again. Leave Icecast running for the time being. #### Configuring IDJC If not running Pipewire start the JACK sound server as follows in order to ensure unimpeded access to the soundcard by Pulseaudio.
    $ jackd -d dummy -r 44100
Run IDJC and select Output from the View menu. In the Output window click Configuration so the configuration section is visible. Click Connection, then New. For Server type you want Icecast 2 Master, for Hostname, localhost, port number should be 8000, mount point can be what you like but choose /listen, login name needs to be source and the password will be the default password, which is hackme. Click Ok to add the server to the list. Click Format. Select MPEG and click the right arrow repeatedly until all the option boxes appear. Click Individual Controls so the controls section is visible and click the button that says localhost:8000/listen. If the button stays in you have made the connection. If the connection fails try 127.0.0.1 in place of localhost. #### Streaming some audio Click the + button on the left media player and using the file selector add a track to the playlist. Click play. Make sure the crossfader is set all the way to the left. Of the player's Audio Feed settings, make sure Stream is on and DJ is off and Monitor Mix is set to DJ. You should be able to see activity in the Str Peak meter. If you can't hear anything right now it's because DJ is off and/or you are running a dummy JACK soundcard, which is what you want for the sake of this test. #### Join the stream as a listener
    $ mplayer http://localhost:8000/listen
After a brief moment audio should start to play and within thirty seconds the listener count in the main IDJC window should have risen to 1. It's possible to add more listeners up to the maximum number currently specified in the Icecast configuration file.
