Note that this is not a standard SSHD service, but a set of Handlers that use the OpenSSH protocol to call ffmpeg or whisper, etc. Programs that need to call MacOS hardware resource capabilities are installed on the local machine and provide corresponding calling interfaces.

What is a Handler

• A Handler is a set of scripts or a string of code that is used to quickly install and set up ffmpeg or whisper
• A Handler also provides an interface for external calls (through the standard SSH protocol)

How to provide external call interface

Use ssh to directly execute commands

ssh -p <PORT> localhost ffmpeg [args...]

ssh -p <PORT> localhost whisper [args...]

This program does not provide access outside of the Handler, that is, it does not trust SSH access requests within the container, such as ssh -p <PORT> localhost cat .ssh/id_ed25519 (obtaining the private key of the macos host), which will be rejected Because this program only provides the installation logic of the Handler and only provides the Handler's calling interface to the outside world.

TODO

• support whisper installer
• save sshexec's stderr into file, keep stderr strictly the same from host process
