The Master Relaying tab includes options for setting up a master relay from another IceCast server. Using Master Relay, the remote IceCast server essentially becomes the source for your own server, and all of the mount points from the remote server are made available on your server.

Options include:

• Master server
  Specifies the hostname or IP address of the master server whose stream(s) you wish to relay.

• Master port
  Specifies the port number of the master server whose stream(s) you wish to relay.

• Master update interval
  Specifies the interval at which the remote stream's configuration is replicated to the local server.

• Master username
  Specifies the username required by the remote server for relaying.

• Master password
  Specifies the password required by the remote server for relaying.

• Relay on demand
  If enabled, your IceCast server will only connect to the remote IceCast server when one or more listeners are connected, and it will disconnect from the remote server when there are no more listeners. If disabled, your IceCast server will remain connected to the remote server and continue receiving the stream even if no listeners are connected.

  Enabling this setting may reduce unnecessary bandwidth usage, but may slightly increase the time required to begin streaming when your first listener connects.
