I am connecting to a write-only FTP site. When I connect, Cyberduck throws an error that access is denied for the LIST -a command. After that error, Cyberduck disconnects from the site, so I cannot upload to it.

Preferred behavior would be to prompt with the error, but maintain the connection so that the user can upload files to the write-only directory. The error message itself should contain the information that this may be a write-only directory, so it doesn't confuse the user.

That should be fixed in the current snapshot build. Please give it a try and report back.

Re-opening this, since there's still a problem. Testing using latest snapshot build (3.6 build 6559)

When I connect, it hangs on "Listing directory ". Transcript is as follows:

220 Microsoft FTP Service
FEAT
530 Please login with USER and PASS.
USER xxxx
331 Password required for xxxx.
PASS ********
230 User xxxx logged in.
PWD
257 "/upload" is current directory.
NOOP
200 NOOP command successful.
SYST

STAT /upload

213 End of status.
PORT 10,1,3,5,248,201
200 PORT command successful.
LIST -a
150 Opening ASCII mode data connection for /bin/ls.

I then tried disabling list commands (all of them), and end up with a disconnect with "2 bookmarks" in the status bar. Transcript there is:

Thanks for the additional information. The server should response error message denying access to the directory. Instead it just ignores the LIST request which is not according to the FTP protocol. Please report to the server vendor.
