Alternatively, you can enable SSH by creating a file named "ssh" in the boot partition of your SD card. This method is particularly advantageous if you don't have access to the Raspberry Pi's graphical interface.
Configuring SSH to Meet Your Needs
Once SSH is enabled, you can customize its settings to align with your specific requirements. The SSH configuration file is located at /etc/ssh/sshd_config. To modify this file, use the following command:
sudo nano /etc/ssh/sshd_config
Here are some common configurations you may wish to implement:
- Changing the Default SSH Port: By altering the default SSH port from 22 to a different number, you can enhance security and reduce the risk of automated attacks.
- Disabling Root Login: To improve security, you can disable root login by setting
PermitRootLogin noin the configuration file. - Enabling Public Key Authentication: This allows you to authenticate using public keys instead of passwords, providing an additional layer of security.
After making any changes to the configuration file, restart the SSH service to apply them using the following command:
sudo systemctl restart ssh
Connecting to Your Raspberry Pi via SSH
Once SSH is properly configured on your Raspberry Pi, you can establish a connection using an SSH client. On Linux and macOS systems, you can utilize the built-in terminal, while Windows users can leverage tools like PuTTY or Windows Terminal for this purpose.
