Netty绑定到错误的接口 [英] Netty binding to wrong interface

问题描述

我在Win7 PC上设置了一个环回适配器，以便可以用Netty绑定到它.事情是我给回送地址分配了IP地址172.16.1.1 /24(这是必需的).但是，当我尝试通过Netty进行绑定时，它改为绑定到127.0.0.1地址-被称为默认localhost IP.所以我只是想知道如何解决这个问题?我特别需要它来绑定IP地址172.16.1.1和端口162的回送适配器.

I set up a loopback adapter on my Win7 PC so that I could bind to it with Netty. The thing is I assigned the Loopback address an IP address of 172.16.1.1 /24 (which is required). But when I try to bind through Netty it instead binds to the 127.0.0.1 address - known as the default localhost IP. So I'm just wondering how I can work around this? I need it SPECIFICALLY to bind to the Loopback adapter with IP address 172.16.1.1 and port 162.

NetUtil  - Loopback interface: Software Loopback Interface 1
NetUtil  - Loopback address: /127.0.0.1 (primary) <--- the problem
NetUtil  - Loopback address: /0:0:0:0:0:0:0:1

与代码有关:

public class SnmpServer {

private final Logger logger = Logger.getLogger("SnmpServer");
//private final static String SNMP_HOST_IP = "172.16.1.1";
private static final byte[] SNMP_HOST_ADDR = {(byte)172, (byte)16, (byte)1, (byte)1};
private final static int SNMP_TRAP_PORT = 162;

final ServerBootstrap snmpBootstrap;

public SnmpServer() {
    snmpBootstrap = new ServerBootstrap();
}

public void bind() throws Exception {
    final EventLoopGroup bossGroup = new NioEventLoopGroup();
    final EventLoopGroup workerGroup = new NioEventLoopGroup();
    final SocketAddress socket =
            new InetSocketAddress(InetAddress.getByAddress(SNMP_HOST_ADDR), SNMP_TRAP_PORT);
    try {
        snmpBootstrap.group(bossGroup, workerGroup)
                .channel(NioServerSocketChannel.class)
                .childHandler(new SnmpChannelHandler());

        final ChannelFuture future = snmpBootstrap.bind(socket).sync();
        //future.channel().closeFuture().sync();
    } finally {
        bossGroup.shutdownGracefully();
        workerGroup.shutdownGracefully();
    }
}

}

推荐答案

解决方法是Netty绑定到位于我的HOSTS文件中的所有地址.我只是导航到该文件，并在其中添加了172.16.1.1 localhost的地址，然后称为InetAddress.getByName("localhost").

The fix was that Netty was binding to all the addresses located in my HOSTS file. I simply navigated to that file and added the address for 172.16.1.1 localhost in there and then called InetAddress.getByName("localhost").
