Once you have installed an SSH server on your IoT device, the following configuration steps are general ones. Different IoT devices may require slightly different steps. Refer to the specific devices documentation for detailed instructions.

Install SSH on your IoT Device

Connect to your IoT device: Connect to your IoT device via a monitor and keyboard or use another method.
Update your system: Open a terminal or command prompt and update your system package lists. Use the following command:
`sudo apt update` (for Debian/Ubuntu-based systems)
`sudo yum update` (for CentOS/RHEL-based systems)
Install the SSH server: Install an SSH server on your IoT device. Use the following command:
`sudo apt install openssh-server` (for Debian/Ubuntu-based systems)
`sudo yum install openssh-server` (for CentOS/RHEL-based systems)
Start the SSH service: Start the SSH service, so it will automatically start whenever the device boots. Use the following command:
`sudo systemctl start ssh`
`sudo systemctl enable ssh`
Check the SSH server status: Ensure the SSH server is running. Use the following command:
`sudo systemctl status ssh`

After you install the SSH server, you need to configure it for secure remote access.

Configure the SSH server

Configure the firewall: Ensure your device's firewall allows SSH traffic (usually on port 22).Use the following command:
`sudo ufw allow ssh` (for Debian/Ubuntu-based systems with UFW)
`sudo firewall-cmd --permanent --add-service=ssh` (for CentOS/RHEL-based systems with Firewalld)
`sudo firewall-cmd --reload`
Set up a user account: Create a dedicated user account for remote access. Use the following command:
`sudo adduser your_username`
Follow the prompts to set a password.
Configure SSH key-based authentication (recommended): This improves security by eliminating the need for a password.
1. On your local machine, generate an SSH key pair (if you don't have one):
  `ssh-keygen -t rsa -b 4096`
2. Copy the public key to your IoT device:
  `ssh-copy-id your_username@your_device_ip_or_hostname`
Disable password authentication (optional but recommended): This further enhances security after setting up key-based authentication.
1. Edit the SSH configuration file:
  `sudo nano /etc/ssh/sshd_config`
2. Find the line `PasswordAuthentication yes` and change it to `PasswordAuthentication no`.
3. Save the file and restart the SSH service:
  `sudo systemctl restart ssh`

Configure Your Android Device

With the server-side set up, the next stage involves configuring your Android device.

Install an SSH Client App
Install an SSH client app from the Google Play Store. Popular choices include Termius, JuiceSSH, and ConnectBot.
Configure the SSH Client
Configure your SSH client app with the following settings:
1. Host: The IP address or hostname of your IoT device. If accessing from outside your local network, this will be your public IP address or a dynamic DNS hostname (e.g., from a service like No-IP or DynDNS)
2. Port: Port 22 (the default SSH port) or the port you specified in your SSH configuration.
3. Username: The username you created on your IoT device.
4. Password or SSH key: Your password (if using password authentication) or your private SSH key (if using key-based authentication).
Connect to Your IoT Device
Save the connection profile and connect to your IoT device. You will be prompted to trust the host key. You will then be logged in and ready to start using SSH.

You will need to configure the SSH client on your Android device with the relevant details about your IoT device, including its IP address, port, username, and password.

Important considerations for advanced configuration:

Port Forwarding: To access your IoT device from outside your local network (e.g., from work or a coffee shop), you'll need to configure port forwarding on your router. This involves forwarding traffic on port 22 (or the port you have chosen for SSH) to the internal IP address of your IoT device. Be aware of the security implications of port forwarding and configure it carefully.
Dynamic DNS: If your public IP address changes (many internet service providers assign dynamic IP addresses), you can use a dynamic DNS service (like No-IP or DynDNS) to provide a stable hostname for your IoT device. This way, you don't have to update the IP address in your SSH client every time it changes.
Firewall: Ensure your IoT device's firewall allows incoming SSH connections. For example, on Debian-based systems, you can use `ufw` (Uncomplicated Firewall) to enable SSH. If you use a different firewall, make sure to allow traffic on the SSH port.
Security Best Practices: Always use strong passwords or SSH key authentication, and keep your devices and software up to date. Consider using a VPN for added security, especially when connecting from public Wi-Fi networks. Regularly review your logs for any suspicious activity.
Troubleshooting: If you're having trouble connecting, here are some things to check:
- Ensure your IoT device is powered on and connected to the network.
- Verify the IP address and port number in your SSH client.
- Check your router's port forwarding configuration (if applicable).
- Check the SSH server status on your IoT device.
- Double-check your username and password.
