Read Only FTP #11

Hi, I would like to implement a read only FTP server. How to do this? Do I need to disable some default command or other things?

Thank you.

Hello, sorry for the late response

You just need to extend NativeFileSystem and override write methods such as writeFile, mkdirs, delete, rename, touch and chmod to make them always throw exceptions. All write commands will be rejected.

Then you can create a custom authenticator that will return that NativeFileSystem instance.
