no read permission = can't upload

2014-07-23 12:28

I need to upload to a ftp site where there is no read permission but winscp is aborting the upload (I tested with read permission ON and it worked just fine but I cant leave it like that):
< 2014-07-23 13:58:41.666 227 Entering Passive Mode (10,253,1,178,19,94).
> 2014-07-23 13:58:41.666 LIST

* 2014-07-23 13:58:41.688 .: Access is denied.

I assume the LIST command is the problem here... can I disable it? (windows ftp.exe does this just fine but has other problems) Here is my current command:

WinSCP.exe /command "open ftp://anonymous:test@192.168.1.178/" "put -delete c:\temp\*.txt /" "exit"

I have tried this against various servers, but was not able to reproduce this. Yes, the LIST (or MLSD) is used, but there's no problem even if the server responds with 550. What FTP server are you connecting to? Can you attach a complete session log file?

The first in the logs is an WinXP machine and the second server is Win 2003 R2 SP2 - no difference with 5.1.7 nor 5.5.4.

winscp5.1.7.log (13.91 KB, Private file)

winscp5.5.4.log (10.97 KB, Private file)

Thanks for the log. I do not have 2003 to test it myself. I've tried 2008 R2 IIS and it works fine.

The difference seems to be that while 2008 rejects listing straightaways, 2003 seems to start data connection for the listing and fails only after that.

But that's difficult for me to verify without having server to test against. Any change to get a test account on your server?
