I think SO_KEEPALIVE is needed, and please log the port it is listening:
```
bootstrap.childOption(ChannelOption.SO_KEEPALIVE, true);
// bind server address
bindFuture = bootstrap.bind(new
InetSocketAddress(port)).syncUninterruptibly();
localAddr = (InetSocketAddress) bindFuture.channel().localAddress();
long endTime = System.currentTimeMillis();
LOGGER.info("Dictionary Server started! Time spent " + (endTime -
startTime) +
", listening on " + localAddr);
```
