Jupyter Server可从外部访问，但拒绝localhost连接 [英] Jupyter Server Reachable from outside but refuse localhost connection

问题描述

我已经使用以下配置在计算机A上安装了Jupyter Notebook服务器:

I've Setup a Jupyter Notebook Server on computer A with the following configuration:

c.NotebookApp.certfile = '.jupyter/mycert.pem'
c.NotebookApp.ip = 'MY_IP_ADDRESS'
c.NotebookApp.keyfile = '.jupyter/mykey.key'
c.NotebookApp.notebook_dir = 'Dropbox/GitHub'
c.NotebookApp.password = 'MY_HASHED_PASSWORD'
c.NotebookApp.port = 8888

服务器启动时，计算机B可以通过 https://MY_IP_ADDRESS:8888 访问此服务器.

When the server starts, computer B can reach to this server with https://MY_IP_ADDRESS:8888.

但是计算机A无法以任何形式到达自身

But Computer A couldn't reach to itself in any kind

# ERR_CONNECTION_REFUSED
https://localhost:8888/
https://127.0.0.1:8888/

# ERR_CONNECTION_TIMED_OUT
https://MY_IP_ADDRESS:8888/

值得一提的是，当我注释掉分配IP地址的行时， localhost 和 127.0.0.1 可以正常工作，但是我无法连接从外部(计算机B)

Worth mentioned is that when I comment out the line which assign the IP address, localhost and 127.0.0.1 works fine, but I wouldn't be able to connect from outside (computer B)

我已经尝试过切换端口，切换浏览器，配置/etc/hosts 和/etc/resolv.conf 以及〜/内的其他一些选项.jupyter/jupyter_notebook_config.py

I've tried switching port, switching browsers, configure /etc/hosts and /etc/resolv.conf and some other options inside ~/.jupyter/jupyter_notebook_config.py

但它们似乎都不起作用
任何建议将不胜感激.

but none of them seems to work
Any suggestion would be appreciated.

经过进一步调查，结果证明这与jupyter笔记本电脑无关.我运行了一个带有以下代码段的简单python HTTP服务器:

After some further investigation, it turns out this has nothing to do with jupyter notebook. I ran a simple python HTTP server with the following snippet:

import sys
from http.server import SimpleHTTPRequestHandler
import http.server


def test(HandlerClass=SimpleHTTPRequestHandler,
         ServerClass=http.server.HTTPServer):

    protocol = "HTTP/1.0"
    host = 'MY_IP_ADDRESS'
    port = 8888
    if len(sys.argv) > 1:
        arg = sys.argv[1]
        if ':' in arg:
            host, port = arg.split(':')
            port = int(port)
        else:
            try:
                port = int(sys.argv[1])
            except:
                host = sys.argv[1]

    server_address = (host, port)

    HandlerClass.protocol_version = protocol
    httpd = ServerClass(server_address, HandlerClass)

    sa = httpd.socket.getsockname()
    print("Serving HTTP on", sa[0], "port", sa[1], "...")
    httpd.serve_forever()


if __name__ == "__main__":
    test()

结果是相同的.我猜这实际上是正常现象，但不是我的偏爱:(

The results are the same. I'm guessing this is actually a normal behavior, but just not my favor:(

因此导致两种情况:

• 用于自连接

• for self-connecting

• 绑定IP地址:"(空字符串)
• 使用localhost或127.0.0.1
• (但其他客户端将无法连接)

用于其他客户端连接

• binging IP地址:"MY_IP_ADDRESS"
• 使用MY_IP_ADDRESS:8888
• (但是服务器本身无法连接)

我添加了一些新标签，希望任何人都可以对此进行提示><

I've added some new tag, hope anyone will have hint on this><

推荐答案

我将回答我自己的古老问题.

I'll be answering my own ancient question.

为了在每个地址上绑定服务，请使用 0.0.0.0 特殊地址.

In order to bind service on every address, use the 0.0.0.0 special address.
