Secure Shell (SSH)

SSH 远程登录SSHCommon

An encrypted network protocol for logging into and controlling another computer's command line remotely.

SSH (Secure Shell) is an encrypted remote-login protocol, proposed in 1995 by Finland's Tatu Ylönen and later standardized by the IETF; the most widely used implementation is the open-source OpenSSH. It lets you securely log into another machine's terminal from your own and run commands there, as well as transfer files (via scp or rsync) and forward ports. It's used constantly in embodied-AI development: logging into a robot's onboard Jetson to edit code, logging into a cloud GPU server to run training, and remote development in VS Code or Cursor is also built on SSH. A common setup is key-based login combined with aliases in ~/.ssh/config.

ExampleOnce the robot and a laptop are on the same Wi-Fi network, running ssh unitree@192.168.123.164 logs into the onboard computer to start the policy-inference program.
