Why I can't access remote Jupyter Notebook server?

Question

I have started a Jupyter Notebook server on my centos6.5 server.And jupyter is running like

[I 17:40:59.649 NotebookApp] Serving notebooks from local directo         


        

Answer 1

In RedHat 7, we need to allow the specific port before running the Jupiter command. Say the port is 8080.

iptables -I INPUT 1 -p tcp --dport 8080 -j ACCEPT

Then we can run it normally. For instance, using:

jupyter notebook --ip 0.0.0.0 --no-browser --port=8080 --allow-root

or whatever you like.

Answer 2

Alternatively you can just create a tunnel to the server:

ssh -i <your_key> <user@server-instance> -L 8888:127.0.0.1:8888

Then just open 127.0.0.1:8888 in your browser.

You also omit the -i <your_key> if you don't have an identity_file.

Answer 3

edit the following on jupyter_notebook_config file
enter actual computer IP address
c.NotebookApp.ip = '192.168.x.x'
c.NotebookApp.allow_origin = '*'

on the client side launch jupyter notebook with login password
jupyter notebook password

after setting password login on browser and then type the remote server ip address followed by the port. example 192.168.1.56:8889

Answer 4

From your command line, we can see your jupyter server is running normally.The reason you can't access your remote jupyter server is that your remote centos6.5 server's firewall rules block the incoming request from your local browser,i.e. block your tcp:8045 port.
sudo ufw allow 80 # enable http server
sudo ufw allow 443 # enable https server
sudo ufw allow 8045 # enable your tcp:8045 port
then try to access your jupyter again.

Maybe you also need to uncomment and edit that place in your jupyter_notebook_config.py file:

c.NotebookApp.allow_remote_access = True

and even shut down your VPN if you have one.

Answer 5

Is that your private IP address? If so you'll need to use your public one. Go to ipchicken to find out what it is. I know you are in the same LAN, but try this to see if it resolves any issues.

Answer 6

I managed to get the access my local server by ip using the command shown below:

jupyter notebook --ip xx.xx.xx.xx --port 8888

replace the xx.xx.xx.xx by your local ip of the jupyter server.
