ipython：通过Web浏览器远程访问笔记本电脑服务器

我想通过网络浏览器远程访问笔记本电脑服务器,following 显示我是如何设置我的笔记本电脑服务器的：

1.生成配置文件

$jupyter-notebook --generate-config
$　cd ~/.jupyter

2.使用以下命令创建SSL证书(Linux和Windows).

req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mycert.pem -out mycert.pem

3.编辑配置文件的配置文件,即生成密码的jupyter_notebook_config.py ..

c = get_config()

# You must give the path to the certificate file.
c.NotebookApp.certfile = u'/home/azureuser/.jupyter/mycert.pem'

# Create your own password as indicated above
c.NotebookApp.password = u'sha1:b86e933199ad:a02e9592e5 etc... '

# Network and browser details. We use a fixed port (9999) so it matches
# our Azure setup,where we've allowed :wqtraffic on that port
c.NotebookApp.ip = '*'
c.NotebookApp.port = 9999
c.NotebookApp.open_browser = False

4.start $jupyter-notebook服务器

您现在应该可以在地址https://[PUBLIC-IP-ADDRESS]:9999访问您的Jupyter笔记本.

启动笔记本：

$ ~ jupyter-notebook 
[I 16:46:58.627 NotebookApp] Serving notebooks from local directory: /home/user
[I 16:46:58.627 NotebookApp] 0 active kernels 
[I 16:46:58.627 NotebookApp] The Jupyter Notebook is running at: https://SERVER_IP:9999/
[I 16:46:58.627 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

但是,当我在https://MY_SERVER_IP:9999打开我的浏览器(在我家,笔记本服务器在我的实验室)时,页面无法打开. Chrome浏览器返回：

ERR_ADDRESS_UNREACHABLE

我该怎么办？
