Cannot Create Remote File via SFTP upload

All, I'm hoping someone might be able to tell me what's going on here.

I am attempting to do a simple sFTP transfer from a Wintel machine to an AIX server. I believe I have all of my rights and groups and things set correctly.

In fact, as the user (sintedi), when logged on to AIX, I am able to create files in this directory (e.g. "touch file" is OK). I also tested by temporarily enabling regular ftp and I was able to do the upload. The only way this doesn't seem to be working is via WinSCP/sFTP connection

When I use the GUI or Command line for WinSCP, I get "cannot create remote file", "permission denied", "error code 3"

Below is a snip of the log. I think the problem is in code below, but I don't know where it is getting that particular set of rights. (AIX output shown below snip).

Can you do touch /sap_imports/p01/sintel/in/test.txt?
Did you try other SFTP client?

Yes, I was able to run both the following as the user:


I just tried with "BitKinex" and "CoreFTP". Both worked fine.[/code]

Please attach their log file.

Here's the log from CoreFTP (base log):

That's quite useless unfortunately. It actually looks like a FTP log. Do they have more verbose logging option? Or can you attach log from BitKinex?

I set logging level to "DEBUG" in BitKinex and then did the transfer. It doesn't look much more than a standard FTP log either. If you have a specific step/logging/information that you'd like me to gather, I'm happy to help. What we have found is that WinSCP is the only software that seems to have this trouble. FileZilla, CoreFTP, and BitKinex all work.

I've attached the log.

OK, thanks. Please attach a complete WinSCP log file.

Attached.

Thanks.
Can you try the same, but disable overwrite confirmations?

Do you have an access to OpenSSH server log?
Can you share server's log showing upload using WinSCP and one of the other clients?
