No FTP possible with MVS / z/OS ( HFS )

[jwinckelmann]

With FileZilla 2.2.12 and some older versions I'm unable
to to transfer data to and from our z/OS mainframe with
HFS file system. I think the directory is formatted
incorrectly as it contains brackets which is not allowed,
like '/u/test/(test.txt)'. It worked correctly with ealier
versions of FileZilla, I don't know which version is the
first version containing this errror.

Here are some extracts of the log:

Still having this problem with latest (2.2.14a right now)?

Hi,

it's a bit complicated. I'd like to to access the Unix part of
MVS on HFS. This doesn't work at all in this release, when I
connect without supplying a default directory I get the
directory listing of my standard MVS files under my user
prefix. For accessing the Unix part I need the default
directory "/u/", which is translated to 'U.' by Filezilla, which
just shows an empty directory. I'm no expert for MVS, but
there must be a way to switch between the standard MVS file
system and the Unix file system. For MVS there are not
slashes in file names / directories, but for Unix.

Hope this helps!

Bye,
Jan

Thanks for the new info. I'll assign this to Botg and
hopefully he can have a look at it when he gets the time.

Hi,

i downloaded Filezilla 2.2.18 and this problem seems to be
not solved.
In the Native MVS environment all is fine (the Native
Environment is the default for the MVS FTP Server) but when
i switch to the Unix Environment of the MVS FTP Server i
can't get any unix files because the request is always
translated into something like "RETR '/xx/xxxxx(copysh)'"
but the request should be RETR '/xx/xxxxx/copysh' or only
RETR copysh because the directory is already set.

Only for clarification on the Mainframe z/OS there are to
different systems running which are served from the same
ftp server one is the native environment which has file
names like 'XXXX.XXX.XXX' and PDS datasets and there is
also a second one which should be treated as a normal unix.
So if i enter a remote directory which starts with / or /sy
it should not be converted to "" or 'sy' it should be sent
as it is / and /sy.

Here is a output of a session with a remote dir of /sy/
after the wrong 'sy' was sent i changed it manually
to '/sy' this worked then i tried to retrieve a unix file
but there where parenthesis added to the filename.
The parenthesis are only needed when i'm in a PDS File on
the Native environment.

I have the same issue:

---

client: FileZilla 2.2.18
server: IBM FTP CS V1R4

Command: SYST
Response: 215 MVS is the operating system of this server.
FTP Server is running on z/OS.

cd '/tmp'
put hello.c
ls hello.c

hello.c not found

cd /
ls -la /tmp*
/tmp
/tmp(hello.c)

---

Apparently FileZilla is detecting that it is communicating
with a Z/OS or MVS FTP server and then changes to "PDS-type"
filenaming conventions.

The MVS FTP server can access "Unix-type" filenames and
subdirectories (contained inside HFS files) in addition to
PDS type filenames and subdirectories.

Maybe it is possible to check for the existence of a "/"
at the beginning of a subdirectory and, if so, use standard
unix filenames and subdirectories.

eg.
cd 'MY.USER.PDS'
vs
cd '/my/subdir'

Thanks for looking into this, Filezilla is one of the
few FTP clients that I have tried which works with TLS
to MVS.

In FileZilla 3 you will be able to specify the server type
in advance. Switching between MVS and Unix mode won't be
possible while being connected.
You can download test versions of FileZilla 3 from
​http://filezilla-project.org/nightly.php

(Actually, if you think about, having two types of directory
structures on one server that are independent of each other
is a totally retarded idea, who came up with that?)
