SSH Remote Terminal

2025-11-26

SSH (Secure Shell Protocol) is an encrypted network protocol used to securely remotely access and manage computers over insecure networks (such as the Internet). It protects communication security and prevents eavesdropping and tampering by establishing an encrypted tunnel between the client and the server.

Prerequisites: When connected to a network via wired/Wi-Fi, the Quectel Pi H1 will automatically obtain an IP address (DHCP protocol).

By default, the system disables the SSH server. Enable SSH using one of the following methods.

On the desktop of a single-board computer

Open Terminal in System Applications

Install ssh-server service

sudo apt install openssh-server

  • If you encounter the following problem, type Y + Enter.

  • For other options that appear later, simply press Enter.

Start ssh-server service

# Enable auto-start
sudo systemctl enable ssh
# Start service
sudo systemctl start ssh
# Check service status
sudo systemctl status ssh
