Hi C.R.,
yes, I know 😊
After reading my post again, I see, it might not be obvious 😊
The question came up after a short discussion with a friend that is a security fanatic person and wanted to reduce the number of open ports dramatically. I shouldn't have asked this question, it seems to be a "strange to silly" approach wanting to do something like that. People with more knowledge about ports/services, please ignore it...
Peter.
