Putting files without read access in the FTP server

2008-06-30 10:33

Hi all,

We're using a FTP server for a daily upload of a backup. Its using anonymous login, and the FTP server is configured to have no read access on the upload directory.

Using standard ftp everything works fine, but WinSCP seems to need read access to the directory. Is there a way to configure WinSCP to work in these conditions?

Problem still exists

2016-02-24 13:26

Hi there,

I'm experiencing the same problem – WinSCP tries to list the directory it should upload to without being instructed to list. As read access is forbidden (I can't influence that decision) it fails to upload. I checked it vice versa on a test system where I'm in control of the FTP-Server and gave the read-permission – it works great.

Here's the log (with some anonymisation):

I can't find a way to prevent the LIST-command, my idea for a workaround is to ignore server responses (as the pure upload with ftp.exe works), but I can't figure out how. Any hint for me?

Re: Problem still exists

Good morning,

thanks a lot for the dev-version. Now the failed LIST does not cancel the connection at the same step as before (see 11:02:15.230), but it fails at a later step (see 11:02:55.245):

As told before I'm using two FTP-server to test, the logs above are from IIS, but my true transfer-destination is another maschine which seems to be even more touchy than the IIS. See below:

So even when LIST-problem using test-IIS is solved there's still a PWD Problem with the real target. @11:23:18.685 WinSCP queries the remote working directory, but this Information was already received @11:23:18.654.

Maybe for environments like mine an "autistic-mode" would be of great use, which must not necessarily be limited to the FTP-Client :wink:

Hello,
I am also running into the same issue when uploading to one of our vendor's FTP servers. The account is configured with no read permissions to the directory, only as a drop box. I have upgraded to the latest version, 5.11.3 in the hopes it would resolve the issue, to no avail.
This is the logs we get from our end:

Connecting to swaftp1.schoolwires.com ...
TLS connection established. Waiting for welcome message...

Copying files to remote side failed.
The specified network name is no longer available.
(A)bort, (R)etry, (S)kip, Ski(p) all: Abort

Uploading using the GUI yields a "Copying files to remote side failed. Access is denied." error.

Any help would be greatly appreciated.

Edit: Below is the detailed log we get:

Hello,
I am also running into the same issue when uploading to one of our vendor's FTP servers. The account is configured with no read permissions to the directory, only as a drop box. I have upgraded to the latest version, 5.11.3 in the hopes it would resolve the issue, to no avail.

This does not look related to directory permissions.
Why do you think so? Can you upload to other folders?
Please start a new thread, as this seems unrelated.
Can you upload files to that folder using any other FTP client? If you can, post its log file.

The issue started occuring when the host changed permissions on the server to be a write-only drop box. Prior to this change, we had not been having any issues uploading.
Here are the logs from FileZilla uploading to the same site/account.

Please double check that you are really using the same credentials with WinSCP as with FileZilla.
As you can see in the log, WinSCP is doing the same command sequence as FileZilla, yet the server responds differently.
Also did you check server-side FTP log file or server-side Windows event log?
