How to stay connected to the GPU server even after your laptop goes to sleep.

Running Jupyter Notebook Server on a Remote Server with tmux

Here’s a step-by-step guide on how to run a Jupyter Notebook server on a remote server using Tmux:

Prerequisites:

• SSH access: You need SSH access to your remote server.
• tmux installed: Make sure tmux is installed on the remote server. You can usually install it using your server’s package manager (e.g., sudo apt install tmux for Ubuntu/Debian).

Steps:

sudo apt install tmux

1. Connect to the server: Use your preferred SSH client to connect to your remote server.
2. Start a new tmux session: Run the following command to create a new tmux session named jupyter_session:

tmux new -s jupyter_session

3. Launch Jupyter notebook: Inside the tmux session, run the following command to start the Jupyter notebook server without opening a browser window:

jupyter notebook --no-browser

jupyter lab --no-browser --ip xx.xx.xx.xx --port 8888

4. Detach from the session: Press Ctrl+B followed by D to detach from the tmux session. This keeps the session and the Jupyter notebook server running even if you close your SSH connection.

Reconnecting to the session:

• To reconnect to the running tmux session later, use the following command:

tmux attach -t jupyter_session

This will bring you back to the tmux session where your Jupyter notebook server is running.

Additional notes:

• You can access the Jupyter notebook interface from your local machine by opening a web browser and navigating to the following URL:

http://<your_server_ip_address>:8888

Replace <your_server_ip_address> with the actual IP address of your remote server.

• You might need to configure a password or token for accessing the Jupyter notebook server depending on your setup.

Using screen:

The steps for using screen are very similar to tmux. Instead of tmux new, use screen -S jupyter_session to create a new session and screen -r jupyter_session to reattach to it.

Security:

It’s important to remember that running a Jupyter notebook server on a public server exposes it to the internet. Make sure you have proper security measures in place, such as password protection and firewall rules, to restrict access only to authorized users.
