[comp.protocols.tcp-ip] PASV support

dino@CDCCENTR.BITNET (Dino Farinacci - Control Data - CDCNET TCP/IP Development) (01/29/88)

    Any implementations  out  there,  other  than  BSD  4.3, that
    support FTP PASV/3-party transfers?

    Yup.  UCLA's Arpanet Control Program  for IBM MVS systems supports
the 3-party model.  In fact, that's its only form of FTP.  ACP is also
remarketed by  ACC as  ACCES/MVS, by Network  Solutions as  DDN/MVS (I
think), and several others I can't recall.

The TOPS-20 FTP server supports PASV.  Given the ancestry of FTPSRT, I
assume the TENEX FTP server also supports PASV.  Neither of the two
TOPS-20 user FTP programs supports use of PASV directly, although one
of them (Stanford's) supports a QUOTE command for the fearless types
who are willing to roll their own protocol negotiations.

The ITS FTP server doesn't support PASV.  The ITS user FTP program
claims to support the use of PASV for third party transfers.  I don't
know if anybody has ever actually used this feature or if it works.
The ITS user FTP also supports QUOTE.

Dino,

TOPS-20 and 4.3BSD both support PASV; 4.2BSD doesn't.

Please do summarize your findings to the list.

I'm currently working on a background file transfer program (BFTP) that 
is based on third party file transfer.  Therefore, I would be very
interested in hearing about the results of your survey, and possibly 
setting up some tests involving dissimilar FTP/TCP implementations.
