Create SSH tunel to a running colab notebook

Colab SSH

Create SSH tunel to a running colab notebook

Prerequisite

• This package only allow SSH public key authentication so you will need to prepare once. You might already had one at ~/.ssh/id_rsa.pub. Refer this to create a new one if you don't had once already
• In order to connect to the SSH tunel from your machine, you will need to install cloudflared from here

Usage

Create a new Colab notebook with a single cell with the following content:

!pip3 install linus-colab-ssh

from colab_ssh import setup_ssh, loop_forever

public_key = '<YOUR_PUBLIC_SSH_KEY>'
setup_ssh(public_key)
loop_forever()

You can use list of public key or link to a raw text file of authorized_keys like this as well

Optinally, you can also specify a Mattermost Webhook URL with mattermost_webhook_address when calling setup_ssh to send a push notification to your Mattermost channel when the SSH tunel is ready.

Run it, after about 2 minutes, you will see something like this:

Command to connect to the ssh server:
✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️
ssh -o UserKnownHostsFile=/dev/null -o VisualHostKey=yes -oProxyCommand="cloudflared access ssh --hostname %h" [e-mail]
✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️
Or you can use the following configuration in your .ssh/config file:
✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️
Host colab
	HostName economic-singapore-place-obtaining.trycloudflare.com
	User root
	UserKnownHostsFile /dev/null
	VisualHostKey yes
	StrictHostKeyChecking no
	ProxyCommand cloudflared access ssh --hostname %h
✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️✂️```

Then voila ;)

Please noted that you must keep the kernel webpage connected to avoid Colab disconnect your kernel early.
