How to Set Up Remote SSH on Raspberry Pi?
Setting up remote SSH on Raspberry Pi is easier than you might think. Follow these steps to get started:
Step 1: Enable SSH on Raspberry Pi
By default, SSH is disabled on Raspberry Pi for security reasons. To enable it:
- Open the terminal on your Raspberry Pi or connect it to a monitor.
- Run the command
sudo raspi-config. - Navigate to “Interfacing Options” and select “SSH.”
- Choose “Yes” to enable SSH and reboot your Raspberry Pi.
Step 2: Connect Raspberry Pi to the Internet
For remote access, your Raspberry Pi needs to be connected to the internet. You can use either Wi-Fi or an Ethernet connection. If you’re using Wi-Fi, ensure that your Raspberry Pi is connected to a stable network.
Step 3: Find Your Raspberry Pi’s IP Address
To connect via SSH, you’ll need the IP address of your Raspberry Pi. Use the command hostname -I in the terminal to find it.
Step 4: Install an SSH Client on Your Android Device
Download a free SSH client app from the Google Play Store. Popular options include:
