   I would like to add a pledge for strategic advice on this
   subject. Since the first message I have elaborated on the
   capacities of the client. Presently my suggestion is based on this
   behaviour:

     IPv4:   1) Try EPSV, PASV, LPSV
             2) Try EPRT, PORT, LPRT

   where the order indicates priority order, and where the use of
   EPSV/EPRT can be toggled on/off by a command "epsv4".

     IPv6:   1) Try EPSV, LPSV
             2) Try EPRT, LPRT

   I have tested all thes mechanisms against the FTP server present in
   OpenBSD.

   My question to all other developers is this: Is this priority order
   acceptable? The inclusion of LPRT/LPSV is made in order to cope
   with potentially deteriorate servers in use. Based on the relative
   invisibility of LPRT/LPSV, that method is assigned a minimal
   priority.

I think this is acceptable, yes.
