You don't need to put "public" before your method, especially if you want to make it a singleton method. public is already the default access type.

To make this a singleton method, simply put either the name of the class, or self before it:

def self.connectViaFTP
...
end

or

def EstablishRemoteConnection.connectViaFTP
..
end

and there's also this interesting format:

class EstablishRemoteConnection
  class << self
     def connectViaFTP
         ..
     end
  end
end

These all have the same result of being able to do this:

EstablishRemoteConnection.connectViaFTP

Also as a side note Ruby naming conventions are generally in the form:

connect_ftp

without any sort of camel casing or such. Class/Module names are the ones that tend to utilize camel case. Whatever works for you though. Though you might also want to keep your class names a bit shorter:

RemoteConnection.ftp_connection
