I was attempting to create an SFTP server and successfully managed to get it to the point where I can view folders from an external location. However, whenever I try to copy folders across from the remote machine to the local machine, FileZilla gives the error "Open for read: permission denied".
In general the solution given online is to give the folder permissions however I made sure that the file I tried to get have the specific permission for the user as well as the "Everyone" setting but neither of these fixed the issue.
Interestingly, I could move files within the remote server, it was just a case of moving them from the remote server to the client. If I attempt to move files from Client to Server, this creates the file but then will not write any data to it (ie. It creates a blank file).
Further details about the problem:
The SFTP server was set up via the instructions found here. In addition, I have also set up a file tree where users are locked within their own folders. This can be seen in my sftp_config file (located in C:/ssh/...) where my settings are as follows:
LogLevel VERBOSE
ForceCommand internal-sftp
AllowTCPForwarding no
X11Forwarding no
Match User User1
ChrootDirectory "C:/SFTP Server/User1"
Match User User2
ChrootDirectory "C:/SFTP Server/User2"
...
The folders located in SFTP Server have their security set such that "Everyone" has full control in order to prevent issues with permissions however I still log in with the Administrator account on the Windows 10 machine running the server but this doesn't change anything in that while I can create and delete files/folders on the server, I can not read or write their data.
In addition, the folders I wish to access have been shared over LAN (Windows' built-in network share) and work correctly which means it's specific to the setup of the SFTP server itself.
Accessing it from the internal IP address, didn't help anything. I also tried using WinSCP however this did not change anything.
As for debug logging, I was unable to get this to work effectively. Logs seen in Event Viewer only showed logging in via SFTP (including when I set LogLevel to DEBUG2) which doesn't help.
Edit: A resolution has been found and the server is working as expected with no issues, however I am not sure what changed and therefore have not answered the question. To help others, between it not working and it working, I set up a printer that connects via SMB to a different folder, and some part of that process fixed the server issues I was having
