Remote Login

IoTDA allows you to remotely log in to devices from the console over the Secure Shell Protocol (SSH). You can enter commands supported by devices to debug functions and locate faults. This facilitates device management and remote O&M. The following describes how to use this function.

Prerequisites

The device runs on Linux.
An SSH server has been installed on the device.
The device has been IoTDA SDK integrated. IoT Device SDK C v1.1.1 or later is supported. For details, see IoT Device SDK (C).
The device is online.

Constraints

Remote connections are based on SSH. IoTDA only establishes SSH channels for devices. You need to develop the management capabilities supported by the console on the device side.
Only the standard and enterprise editions support remote login. The domain name access mode must be provided for application access of the enterprise edition.
Only one remote connection can be enabled for a device at a time. Up to 100 devices can be remotely logged in at a time for each instance of a tenant.

Procedure

Access the IoTDA service page and click Access Console. Click the target instance card.
In the navigation pane, choose O&M > Remote Login.
