Using Google Colab and ngrok to serve it temporarily

I have tried following to serve and activate using ngrok in google colab but I am not getting it work. I have changed http to tcp.

Setup Google Colab

1. Visit https://colab.research.google.com/
2. Sign in / Sign up using google account
3. Create new note book

Get authorised ngrok tunnel

1. Download ngrok Google Colab

!wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip

1. Unzip

!unzip ngrok-stable-linux-amd64.zip

1. Sign up at ngrok and get authtoke

!./ngrok authtoken <your-auth-token>

1. Start ngrok and python kms server

!./ngrok tcp 8081 & python3 /content/py-kms/py-kms/pykms_Server.py 0.0.0.0 8081

Thanks for maintaining the project

Hi, I think this is because you’ve configured Ngrok as a HTTP tunnel and as a result, Ngrok is attempting to terminate and re-establish a HTTP connection to an RPC service running on a plain TCP port. I think you should be able to resolve this by running ngrok tcp 1688. Thanks,Matt07.12.2022, 19:12, “kryptoniancode” @.***>: I have tried following to serve and activate using ngrok in google colab but I am not getting it work. Setup Google Colab

Install and run ngrok

Intall

!pip install pyngrok==4.1.1

Get tunnel using ngrok

from pyngrok import ngrok public_url = ngrok.connect(port=‘8000’) print (public_url)

Run python kms server

!python3 /content/py-kms/py-kms/pykms_Server.py 0.0.0.0 8000

Error These are following errors in ngrok, google colab and activating office google colab This errors come when the link opened in browser.

ngrok When opening the url in browser.

office Note: In above image Invalid RPC request type 84. come from browser when url opened in browser. When setting the url as ngrok using sethst does nothing.

Following can also be done to get authorised ngrok tunnel

Download ngrok Google Colab

!wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip

Unzip

!unzip ngrok-stable-linux-amd64.zip

Sign up at ngrok and get authtoke

!./ngrok config add-authtoken <your-auth-token>

Start ngrok and python kms server

!python3 pykms_Server.py 0.0.0.0 1688 & ngrok http 1688

If above issues can be resolved then it be easier activate lower end devices without installing docker, virtual machine, wsl2 etc. Thanks for maintaining the project

@simonmicro can you close this as resolved and also give me permission to close issues?

Side note: I did reply via email about using ngrok tcp but appears it was not delivered and added to the thread.
