SSH Remote Terminal

2026-01-30
SSH (Secure Shell Protocol) is an encrypted network protocol used to securely access and manage computers remotely 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: The device is connected to the network via wired or Wi-Fi connection. The Quectel Pi H1 Smart Single-Board Computer will automatically obtain an IP address via the DHCP protocol.

The SSH server is disabled by default. It can be enabled using one of the following methods.
