in thread How to connect to SFTP via OpenSSH

You were right about incorrect credentials. I was able to resolve that issue. Now for some reason it fails when trying to put a file on my SFTP server. I get the message:

Can't put. Couldn't open remote file 'sftptest': Folder not found: sftptest at line 25.

So why is it looking for a folder called sftptest when putting? I've clearly defined that as a file? Also, what does it mean "can't open remote file"? This isn't a remote file yet...?

    Folder not found: sftptest
    This is the error returned by the remote server. Looks like some Windows server, I would not expect too much from it.

    Enable debugging of Net::SFTP::Foreign at the beginning of your script to see what is actually happening under the hood: 

    $Net::SFTP::Foreign::debug = -1;

        The client ask for opening a file for writting (2, SSH2_FXP_OPEN) and the server replies with a general failure code (4, SSH2_FX_FAILURE).

        I blame the server. For a work-around try using an absolute path or calling set_cwd first.

        Do you know which software is running on the server? if you connect to the ssh port using netcat or some similar tool it would tell the vendor and version of the SSH server.
