linux - 无用的IP地址设置用于端口监听

我在 Vagrant 的实例中运行以下命令:printf 'HTTP/1.1 302 Moved\r\nLocation: https://www.eff.org/' | nc -l 2345在我的主机上，我想访问<ip of my vagrant server>:2345并重定向到https://www.eff.org/。
重定向不会发生，浏览器只会继续加载。
我的Vagrantfile:

Vagrant.configure("2") do |config|

  config.vm.box = "ubuntu/trusty64"
  config.vm.network "private_network", ip: "192.168.33.10"
  config.vm.network "public_network"

end

如何设置Vagrantfile并确定vagrant Linux服务器的IP地址，以便在使用端口2345的主机上的浏览器中使用？
我试过了:

curl ifconfig.me，得到:46.128.200.193

hostname -i，得到:2a02:2455:25f:e000:a00:27ff:febd:cd6c%4 10.0.2.15 192.168.33.10 192.168.0.16

ifconfig，得到:

在主机上，我尝试在浏览器中进行访问:

192.168.33.10:2345，得到:

GET / HTTP/1.1
Host: 192.168.33.10:2345
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:77.0) Gecko/20100101 Firefox/77.0

10.0.2.15:2345，什么也没有得到

46.128.200.193:2345，什么也没有得到

但是到目前为止，没有Vagrantfile的设置以及IP地址与端口2345的组合都将我重定向到eff.org。

最佳答案

我有不同的方法。
我正在使用python简单的http服务器模块。
代码来自other answer

#!/usr/bin/python
import SimpleHTTPServer
import SocketServer

class myHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
   def do_GET(self):
       self.send_response(301)
       self.send_header('Location','http://www.eff.org')
       self.end_headers()

theport = 1234
Handler = myHandler
pywebserver = SocketServer.TCPServer(("", theport), Handler)

print "Python based web server. Serving at port", theport
pywebserver.serve_forever()

关于多个接口(interface)。
确保输出

sudo lsof -i -P -n | grep LISTEN

*:1234，即所有接口(interface)均用于此端口。

web_fwd.p 2594         dev    3u  IPv4  60354      0t0  TCP *:1234 (LISTEN)
