Correct. The Windows FTP client meets the requirements of command-line, Windows, MVS, but it only runs in active mode, so it can’t be used in conditions that block active mode FTP.
In my case it is Appgate SDP that is incompatible with active mode.

I use the default Windows ftp client to transfer files to and from my employer's z/OS systems all the time, and never had any issue. CAVEAT: All transfers are happening from a company laptop operating INSIDE my employer's VPN network, never from outside that network, so passive mode has never been needed.

The ones that meet the first two requirements fail on the 3rd, because they try to be too smart. They try to track and cache the directory structure instead of passing the commands straight through to the server, and thus get confused by the MVS data set syntax. * without running in a Linux subsystem -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Mark Zelden Sent: Thursday, November 10, 2022 5:25 PM To: [email protected] Subject: Re: FileZilla for "ftp" from W11 to z/OS On Thu, 10 Nov 2022 17:09:43 -0600, Paul Gilmartin <[email protected]> wrote: >On Thu, 10 Nov 2022 15:52:01 -0500, Steve Smith wrote: > >>I set up Filezilla with two "hosts": one as MVS, one as Unix.

If using a DOS prompt you can switch back and forth all you want between "classic" MVS and z/OS Unix. None of clients I've worked with allow it from the GUI. If you FTP into classic z/OS and then type "/" for the file name in the site directory / search bar (whatever you want to call it) you will get a syntax error. If you start the FTP in unix mode it will think you are looking for a unix directory of whatever name you use (enclosing in quotes ends up generating cwd /'whatever'). > >But are there possibly ambiguous directory names? No since you are in either "z/OS" or "unix" mode in the GUI. > >Does either the Filezilla client or the z/OS server respect the "//" >prefix as indicating a DSN? No. But why would you need or use that syntax since you are either FTPing into z/OS or Unix in any given connection. BTW, FileZilla does allow multiple active FTPs so you could FTP into both at the same time and it will be in two tabs.
