Can netty bind to multiple ports?

[Frederic Bregier]

Hi,

I think you can write:

     bootstrap.setPipelineFactory(new FastMarketDataPipelineFactory());
     ChannelGroup allChannels = new DefaultChannelGroup();

     for (SocketAddress port : fromFile) { // where fromFile could be a list
of InetSocketAddres(ports)
         Channel serverChannel = bootstrap.bind(port); // it will create a
new "father" channel for each port
         allChannels.add(serverChannel);
     }

and when you shutdown:

     // Close the serverChannel and then all accepted connections.
     allChannels.close().awaitUninterruptibly();
     b.releaseExternalResources();

This way you only have one bootstrap (it is made to be used as many times
you wanted) which produces several server channels listening on different
ports.

HTH,
Frederic
