我在172.16.1.218上运行以下node.js服务器：

var net=require('net');

var server = net.createServer(function (socket) {
        socket.write("Echo server\r\n");
        socket.pipe(socket);
});
server.listen(6001, "172.16.1.218");

我可以远程登录到它，它会按预期的方式回显。

我有以下运行在172.16.1.224上的node.js服务器：

var net = require('net');

var server = net.createServer(function (socket) {

  // Every time someone connects, tell them hello and then close the connection.
  socket.addListener("connect", function () {
    sys.puts("Connection from " + socket.remoteAddress);
    socket.end("Hello World\n");
  });

});

// Fire up the server bound to port 7000 on localhost
server.listen(6001,"172.16.1.218");

但是，当我尝试运行它时，出现以下错误：

node.js:134
        throw e; // process.nextTick error, or 'error' event on first tick
        ^
Error: EADDRNOTAVAIL, Cannot assign requested address

    at Module.load (module.js:334:31)
    at Function._load (module.js:293:12)
    at Array.<anonymous> (module.js:421:10)

我已关闭所有防火墙等。对于此错误，我一无所知。希望有人能提供帮助。

提前谢谢了，
