net/ftp.rb can't list ftp sites behind a firewall ,
to solve this issue ftp passive mode must be used , the support is in the code but needs means to activate it !
so add to the FTP class attributes to change and access passive state :
attr_reader :passive
attr_writer :passive

and a program can use:
    ftp.passive = true
to use passive mode
