 +sudo airtime-easy-setup 
 +</code> 
 + 
 +===== Configuración ===== 
 + 
 +Asumo que airtime esta instalado en un servidor. En este ejemplo el servidor esta en la DMZ y tiene como nombre DNS "airtime.example.com" 
 + 
 +1. Editar archivo de config: 
 + 
 +<code> 
 +sudo cp /etc/airtime/airtime.conf /etc/airtime/airtime.conf.old 
 +sudo vim /etc/airtime/airtime.conf 
 +</code> 
 + 
 +Y ajustar la variable: 
 + 
 +  base_url = airtime.example.com 
 +   
 +2. Tras cambiar una configuracion, actualizar base de datos: 
 + 
 +  sudo airtime-update-db-settings 
 + 
 +3. Editar el virtualhost: 
 + 
 +<code> 
 +sudo cp /etc/apache2/sites-available/airtime-vhost.conf /etc/apache2/sites-available/airtime-vhost.conf.old  
 +sudo vim /etc/apache2/sites-available/airtime-vhost.conf  
 +</code> 
 + 
 +Y dejarlo tal que asi: 
 + 
 +<code> 
 +<VirtualHost *:443> 
 +      SSLEngine on 
 +      SSLProtocol all -SSLv2 
 +      SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem 
 +      SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key 
 +      Header always set Strict-Transport-Security "max-age=31536000" 
 + 
 +      ServerName airtime.example.com 
 + 
 +      ServerAdmin root@localhost 
 + 
 +      DocumentRoot /usr/share/airtime/public 
 +      DirectoryIndex index.php 
 + 
 +      <Directory /usr/share/airtime/public> 
 +              AllowOverride all 
 +              Require all granted 
 +      </Directory> 
 +</VirtualHost> 
 + 
 +<VirtualHost *:80> 
 +      ServerName airtime.example.com 
 +      ServerAdmin root@localhost 
 + 
 +      DocumentRoot /usr/share/airtime/public 
 +      DirectoryIndex index.php 
 +      Redirect permanent /login https://airtime.example.com/login 
 + 
 +      SetEnv APPLICATION_ENV "production" 
 + 
 +      <Directory /usr/share/airtime/public> 
 +              AllowOverride All 
 +              Require all granted 
 +      </Directory> 
 +</VirtualHost> 
 +</code> 
 + 
 +4. Recargar la config de apache: 
 + 
 +  sudo apachectl -k graceful 
 + 
 +5. Ya se deberia poder entrar en: 
 + 
 +  http://airtime.example.com 
 +===== ID3 ===== 
 + 
 +[[http://en.wikipedia.org/wiki/ID3#ID3v2_frame_specification_.28Version_2.3.29|Listado de etiquetas ID3]] 
 + 
 +Para asignar etiquetas: 
 + 
 +  sudo aptitude install id3v2 
 +   
 +Asignar una etiqueta: 
 + 
 +  sudo id3v2 --TBPM "128" file.mp3

 +
 +<code>
 +cd /etc/php5/apache2/conf.d
 +sudo ln -s /etc/php5/conf.d/airtime.ini .
 +sudo apache2 restart
 +</code>
 +
 +
 +Now you will see a right path in the logs:
 +
 +BEFORE:
 +
 +<code>
 +2014-12-06T13:19:34+01:00 INFO (6): [StoredFile.php : uploadFile() : line 901] - /usr/share/airtime/application/models/StoredFile.php:uploadFile(): filename=p198foha3paeupmt1u6116tj1dfd4.mp3 to /plupload

 +
 +AFTER:
 +
 +<code>

 +
 +====== Icecast2 ======
 +
 +  sudo aptitude install icecast2
 +  
 +  /etc/icecast2/icecast.xml
 +  
 +Just the mountpoint:
 +
 +<code>
 +        <mount type="normal">
 +            <mount-name>/broadcast01</mount-name>
 +            <password>secret</password>

 +        </mount>
 +</code>
 +
 +====== Darkice ======
 +
 +  /etc/darkice.cfg
 +  
 +<code>
 +[general]
 +duration = 0 # duration of encoding, in seconds.

 +localDumpFile =

 +description = Description 
 +url = http://example.com
 +genre = music # genre of the stream
 +</code>
 +
 +Arrancar:
 +
 +  sudo darkice -v5 -c /etc/darkice.cfg 
 +
 +===== Errores =====
 +
 +  * DarkIce: AlsaDspSource.cpp:173: can't set channels [2]
 +
 +La causa es que en el archivo de configuración se especifica que el dispositivo puede grabar en stereo:
 +
 +  channel = 2
 +
 +Y el dispositivo solo soporta mono. Solución:
 +
 +  channel = 1
