I see telnet mentioned in many posts. Telnet is not installed by default here... do i need it? Can ssh be used instead? ---

You don't need neither telnet nor ssh. Can you show any examples where telnet is mentioned? ---

I am not sure I understand what you mean by > I can curl them and ping them but they are still 'na'.
