问题
I want to access a jupyter notebook via an SSH tunnel and follow this recipe
https://hsaghir.github.io/data_science/jupyter-notebook-on-a-remote-machine-linux/
To sumarize - : 1. Log in remote machine
user@local_host$ ssh user@remote_host
remote_user@remote_host$ jupyter notebook --no-browser --port=8889
2.In a new terminal:
user@local_host$ ssh -N -L localhost:8888:localhost:8889 remote_user@remote_host
3.Then go to a browser and go to
localhost:8888
Now here is my problem: I can access the remote machine only in two steps
ssh -X username@server
ssh -KX my_pc_name
and the jupyter notebook is only installed on my_pc_name.
What do I write for the second step, when I replace the first line of the first step by my longer log in procedure ?
When I plug in remote_user = username and remote_user = my_pc_name, I get an security error from the jupyter notebook asking for a token. The token that I get from step one, running the jupyter notebook will not work.
One solution could be to combine the two ssh log in steps to one.
回答1:
It seems 'server' is your gateway server, and that 'my_pc_name' is accessible only from there. Try establishing two connected ssh tunnels like so:
https://medium.com/@sankarshan7/how-to-run-jupyter-notebook-in-server-which-is-at-multi-hop-distance-a02bc8e78314
So I would do this. Open a terminal and run:
ssh -f username@server -L 8888:localhost:8889 -N
This connects your local machine to the jump server and does port forwarding.
Then open a new terminal and run:
ssh username@server
ssh -f my_pc_name -L 8889:localhost:8889 -N -K
This should connect you to the jump server and do port forwarding between jump server and my_pc_name.
Then open another terminal and run:
ssh -X username@server
ssh -KX my_pc_name
jupyter notebook --no-browser --port=8889
This should connect you to my_pc_name and run the jupyter notebook server there.
Finally go to your browser on your local machine and access:
localhost:8888
You do have the -X option in your ssh connection string, which indicates X11 windowing (a type of remote desktop for linux). Try dropping it and see if it still works, else you may have to keep it. Also, -K indicates forwarding of Kerberos tickets, which you probably need to allow file access, so I kept it.
You may have to play with a combination of these on your machine to get it working.
