I am trying to use the Jupyter notebook from a remote server using the server's IP address and have followed the suggestions from this SO question:
Why I can't access remote Jupyter Notebook server?
The following command has worked in all the server instances but I am facing issue with one particular instance:
jupyter notebook --ip xx.xx.xx.xx --port 8889 --allow-root
In this particular server instance, this throws the following error:
File "/root/anaconda3/bin/jupyter-notebook", line 11, in <module>
sys.exit(main())
File "/root/anaconda3/lib/python3.8/site-packages/jupyter_core/application.py", line 270, in launch_instance
return super(JupyterApp, cls).launch_instance(argv=argv, **kwargs)

File "/root/anaconda3/lib/python3.8/site-packages/tornado/netutil.py", line 174, in bind_sockets
sock.bind(sockaddr)
OSError: [Errno 99] Cannot assign requested address
The issue seems to be with the use of IP address and not the port despite the following settings on jupyter_notebook_config.py
c.NotebookApp.ip = '0.0.0.0'
c.NotebookApp.allow_origin = '*'
c.NotebookApp.allow_remote_access = True
I have looked at solutions on SO and Github and most of them are for localhost and not specific IP addresses.
Can someone point to what could be the issue? Thank you.

I have set up a raspberry webserver running on my school lan network ,other people are connecting with arduino,sometimes when they connect i get this error:
Exception happened during processing of request from ('172.17.17.66', 49153)

Can someone tell me what means? Is a problem of my server or their socket? If needed i can post my code.
The last line:
error: [Errno 104] Connection reset by peer
Means the client dropped the connection. I'd look into the Arduino code first.
Setup
Windows 10
Docker for Windows v18.09.0
AWS SAM CLI v0.10.0
Python 3.7.0
AWS CLI v1.16.67
dotnet core sdk v2.1.403
Powershell v5.1.17134.407
Problem
I'm following the quickstart for AWS SAM Local (as well as the readme generated once the init command is executed below), using the dotnetcore2.1 runtime.
I've run the following command to initialise AWS SAM for use with dotnetcore2.1
sam init --runtime dtonetcore2.1
Then I created the package by running
build.ps1 --target=package
Finally I start the local API Gateway service by running
sam local start-api
I then open a browser and navigate to http://localhost:3000/hello where I'm presented with the following:
PS C:\Users\user_name\Documents\Workspace\messaround\aws-sam\sam-app> sam local start-api

What I've tried
Resetting the shared drive credentials
Initially I though this was a permissioning error between my Windows drive and the VM running docker... After searching the docker forums I found this article which I've followed. However this doesn't seem to have changed the error message
Any suggestions would be greatly received. Thanks
That's how I fixed my problem:
When SAM CLI sees a zip, it unzip into a temp directory (looks to be C:/Users/user_name/AppData/Local/Temp/tmpq0zka7a7 in your case).
Docker must have access to that folder.
In my case, I've created a local user to give Docker access to shared drives and that local user didn't have access to C:/Users/user_name.
I gave it access and got my problem sorted. Maybe you can fix it the same way.
Try to run the following:
docker run --rm -v c:/Users/user_name:/data alpine ls /data
It should list c:/Users/user_name content if all is fine.
Good luck!
with cloudera install doc step by step I have in trouble with Install Agents
like this:
It said install failed and can not receive signal.
And I find the log like this:

I try to solve it with google I already check these setting.
/etc/cloudera-scm-agent/config.ini the port set 7182 and server_host set ryze-1.bigdata.com.
iptable altready shutdown with sudo service iptables stop
ryze-1.bigdata.com is reachable. and telnet ryze-1.bigdata.com 7183 can succeed.
OS: Centos7.4
Platform: AliCloud
So what can I do? Any one can help me ?
I closed the ssl option.
Everything is fine now.......

The Jupyter Notebook is running at:
The notebook itself says the kernel is loading, but it never finishes loading.
I had the same problem after upgrading notebook.
Upgrading tornado and ipykernel fixed it for me.
If you use the following commands in your terminal, it should work:
pip install tornado==5.1.1
and
pip install -U ipykernel
After rolling back "tornado" and updating "ipykernel" everything worked.
