The remote service access feature includes remote connection through the SSH protocol,
remote file management through the SFTP protocol, and other remote access services
through the TCP protocol.
Link IoT Edge (LE) provides the remote service access feature by default.
Remote connection and remote file management are implemented based on the SSH protocol.
They allow you to remotely log on to gateway devices, control the devices, and manage
files. The username and password are the same username and password of the SSH service
on the Docker images or the gateway.
