如何从 Google Colab Notebook 中杀死 Ngrok 隧道

Question

I am running Streamlit app from Google Colab Notebook . Due to some limitations of sending out the URL of Streamlit app to outside, I follow the tutorial of using Ngrok for sending URL via tunnel. I know that with a single ngrok client session , I can't run more than one tunnel. But in my case, I want to rerun and reconnect my Streamlit app to ngrok again. So in order to do so, I want to kill the running Ngrok tunnel first.

So please anyone, could you tell me how to kill ngrok from Colab Notebook ?

Answer 1

It's likely you have an orphaned Colab. Go to Runtime -> Manage Sessions, and terminate all of them and then try again.

Answer 2

You need to find the processes on which ngrok tunnel is running and kill it.

command to find the processes ids

ps -eaf | grep {{port on which ngrok is running}}

This will result in a list of processes that has a text match with the port number. Identify the ngrok tunnel processes and kill those processes running the following command

sudo kill -9 {{process id}}
