Legacy FS Support

[twelvebaud]

My father uses an ancient FTP server as part of his job.
His FTP server supports accessing directories using slash
for a delimiter, but the files he wants to access are not
accessible via this method. His directory change request
must follow the pattern "CWD 'QW.U.SNOW.ALL'" for
example, and the server responds normally.
Unfortunately, FileZilla wraps this in slashes when he
tries to change directories in the "Remote Site" pulldown.

If possible, add a server-by-server option to specify
directory delimiters, or to set the directory raw rather
than parsed.

[Tim Kosse]

Can you please give an example how the server replies to the
PWD command?

[twelvebaud]

Command: CWD 'QW.U.ALL.SNOW.ALL2003'
Response: 250 'QW.U.ALL.SNOW.ALL2003.' is current
working directory prefix
Command: PWD
Response: 257 'QW.U.ALL.SNOW.ALL2003.' is current
working directory

Please try the latest test release from
​http://filezilla.sourceforge.net/FileZilla_setup.exe

[weiminlee]

I'd like that option as well. It's similiar to connecting to the
ftp services on a MVS system. This is what I get on the pwd
command on our MVS.

ftp> cd 'fx.rfx.dev.fs840'
250 "FX.RFX.DEV.FS840." is the working directory name prefix.
ftp> pwd
257 "'FX.RFX.DEV.FS840.'" is working directory.
ftp>

What's the status regarding this item?

[Alexander Schuch]

Can you try the latest version of FileZilla 3? If it doesn't work by default, can you add your site to the Site Manager and try different server types in order to check if any of them work for that server?

[twelvebaud]

My dad no longer has access to an MVS system, so I can't really test... Perhaps weiminlee can...

[Alexander Schuch]

I then set this item to pending again and we wait for weiminlee to hopefully give us a reply as well.

[weiminlee]

Seems to navigate fine, but listing directory contents when files exist doesn't seem to work. I haven't tried any other commands.

We migrated our PeopleSoft system from DB2/MVS to Windows/MSSQL a year ago so I've had almost no need to access our mainframe since. We do on the other hand transfer files in unattended command line/batch mode to and from MVS and I wrote a VBS wrapper around Windows FTP for that.

I can't speak for everyone, but for me, this feature now falls into the "nice to have" category.

[Tim Kosse]

wiminlee, your log looks very strange, there's a missing PASV/PORT between the last CWD and the LIST. Can you please attach another log with debug level set to 3?

[weiminlee]

Looks like my submit of the LIST command didn't make any difference. The disconnect was received from the server after the CWD command...

[Tim Kosse]

Thanks for confusing me greatly. You can't just use raw commands without telling me and then post the log. Especially since LIST cannot be used like that.

[weiminlee]

Sorry about that, I should have been clearer. I did that because after connecting to MVS, the browser frame is empty and the Remote site: field is grayed out so I couldn't enter the path I want to navigate to. So because of that I tried issueing raw commands for navigation.

[Alexander Schuch]

Lots has changed in the past 4 years. Do you still have that issue or does FileZilla 3.5.3 properly handle your mainframe system now?

[Alexander Schuch]

No reply for more than 28 days.
