Unable to enable ssh port forwarding #55

Closed xd003 closed 3 years ago

xd003 commented 3 years ago

As mentioned in readme , i first connect to ssh , then enter the colab password ,ssh connects well

Now i run the vnc command inside colab ssh , it immediately gives me the following error ..

colab@0.tcp.in.ngrok.io's password: 
bind: Cannot assign requested address
channel_setup_fwd_listener_tcpip: cannot listen to port: 5901
Could not request local forwarding.

please fix this issue

I think you are running commands in wrong way. I will rewrite "How to use" part in Readme.md more clearly.

After remocolab.setupVNC() you need to run the ssh command under If you use VNC: in your local PC, not under Command to connect to the ssh server:. After login to colab server, you can run TurboVNC viewer on your local machine. You don't need to run any command after logined to the server.

I also wrote how to use VNC in my blog post: https://internet-of-tomohiro.netlify.app/google_colab/vnc.en.html
