server does not support SFTP extension

Any help is appreciated -

Client is - WinSCP3.7.2 (Build 262)

Server is - OpenSSH 3.7.1p2

I login and authenticate successfully but the directory listing is empty and it does not show any of the directory structure on the server using the gui. Same result from command line sftp.

When I drag and drop a file, the file is transferred but I do not see it in the window. I use the command line to verify the file was successfully transferred.

WinSCP>Commands>Server/Protocol Information says that "The server does not support any SFTP extension". SFTP is Version 3 and SSH Protocol is 2. Any ideas on why I am unable to see the directory listing?

What is your server? On what OS? Can you post a log file?

Server is a Intel box running Linux kernel 2.4.22. Log file from WinSCP is below. The log file was me simply logging in via the WinSCP GUI>I then saw a listing of directories but there were no names associated with what I saw>I went up one directory>I saw no entries even though I know they exist.
