SSH is Blocked!

for security, many network admins block port 22 (the normal SSH port), so you can not SSH in or out of a network

so what do you do if you still need to SSH to a remote computer?

AWS Cloud Shell

GitHub CLI

• install gh cli for your operating system

• login to GitHub

  • gh auth login 

• once logged in, show all your current Codespaces

  • gh cs list 

• SSH (using gh cli) to the Codespace you want

  • gh cs ssh 

• Note: your Codespace MUST have the SSH daemon running

  • you can add ssh to the .devcontainer definition

TTYD

• load this program on the remote server you would like to connect to

• ensure that port 8080 (from the example below) is open on the server

  • for AWS ensure the "security group" has port 8080 and 22 inbound open

• example start command:
  ttyd -c mr-coxall:password -W -p 8080 bash 

• additional help

Repl.it WSSH client

• fork this Repl.it to your account

• use the web client to SSH into your server
