Remote SSH (with no port fordwarding)

A little python script which lets you ssh into your device without configuring port forwarding. This isn't a viable solution for manage servers and it only should be used in testing environments, you should always configure port forwarding and firewall according to your needs.

How does it work?

Basically Ngrok allows you to create secure tcp tunnels to ports on your server without needing to configure the port forwarding rules. In fact this isn't a proper SSH connection, but it's more a shell over https. I'm using Telegram cause it's free and it's a good way to communicate the address to SSH too. Theoretically you can even use Twilio APIs to send a SMS but it's not free hence me choosing Telegram. I used to use this to manage my grandma's Ubuntu Laptop since we lived in different cities.

Getting Started

Requirements

• A SSH server running on a Linux machine on port 22.
• telegram Python library.
• psutil Python library.
• A ngrok account.

Instructions

• On Telegram create a new bot by using @BotFather and get the Token.
• Click on this link, substitute the token in the url and refresh the page. You should be getting a JSON: you need to note down the ChatID field.
• Follow the instruction on https://ngrok.com/download (the script assumes that ngrok is available in $PATH on Linux),
• Clone the repository: git clone https://github.com/XxXTommyXxX/RemoteSSH.
• CD into it: cd XxXTommyXxX/RemoteSSH.
• Install psutil and telegram libraries in your home project pip3 install psutil telegram.
• Edit the script variables bot_token, bot_chatID.
• Start the bot on Telegram.
• Run the script: python3 ssh_ngrok.py.
• A tcp://foo.bar:12345 should pop up.
• Now you can ssh to your device: ssh user@foo.bar -p 12345.
