The answer is Yes, it can. FileZilla is one of the few FTP clients that understands MVS FTP requirements.
FileZilla can usually guess that it is an MVS server, but you can help it by setting up the site in Site Manager, with server type set to MVS, OS/390, z/OS. Failing to open a data port is usually a sign of a firewall blocking the data connection, either on the client machine (e.g. Windows Defender) or in between you and the server. Firewalls often don't like Active FTP. Also some VPN clients can't handle it. Nor when your traffic is going through NAT. (The reason is that the data connection is opened from server port 20 back to a random port on the client.) FileZilla defaults to Passive mode which is more likely to make it through. This is controlled by Site Manager > Transfer Settings > Transfer mode. However, uploading to MVS from a non-MVS client is a problem with every FTP client I've used (and with IND$FILE transfers), because when you are creating a new file, you have to set the space and file attributes. So what's easier is to pre-allocate the file on the MVS machine, and then upload *replacing* the pre-allocated file. Still easier, generally, is to upload to a new member in a PDS library, where the library already exists -- then you don't have to provide space or DCB info. BUT I've found that uploading to a PDS member is difficult in FileZilla when using drag-and-drop. In that case, I use Transfer > Manual transfer, and set the remote path and file directly. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Steve Thompson Sent: Thursday, November 10, 2022 1:30 PM To: [email protected] Subject: FileZilla for "ftp" from W11 to z/OS If any of you have used FileZilla, will it support copying a file from Winderz to, as an example, ABC.XYZ.JCL? I have not been able to deduce how to get this to work, scanning their FAQs (which had a few issues about PDSEs) and forums... Filezilla seems to be oriented to *nix or NTFS type file systems. What is driving this is, ftp will make the initial connection and then it fails to open a data port. So I am trying other tools that understand SFTP, ssh and the like.
