Platform
The operating systems or virtual machines the SSH servers are designed to run on without emulation; there are several possibilities:
- No indicates that it does not exist or was never released.
- Partial indicates that while it works, the server lacks important functionality compared to versions for other OSs but may still be under development.
- Beta indicates that while a version is fully functional and has been released, it is still in development (e.g. for stability).
- Yes indicates that it has been officially released in a fully functional, stable version.
- Dropped indicates that while the server works, new versions are no longer being released for the indicated OS; the number in parentheses is the last known stable version which was officially released for that OS.
- Included indicates that the server comes pre-packaged with or has been integrated into the operating system.
The list is not exhaustive, but rather reflects the most common platforms today. Template:Sort-under
