[IBMiOSS] sFTP File Transfer Failure

Open Source Group,

This is my first attempt at sFTP on the IBM i The System is running OS
V7R3M0. I've searched the Midrange Archive and found nothing helpful.

My Client has been ask to send .txt files to their bank via sFTP. I've
setup ssh and sFTP to the best of my knowledge. I created a Public Key and
exchanged with the bank. The bank has verified that the connection is
established. My problem lies in the transfer of the data file.

It's just a simple PUT statement run from a script using QSHONI. Which
I've successfully used in the past to run cURL scripts.

put /home/CATOOSA/filename.txt

quit

 

The problem may be in the following command, although I find very little
documentations on the purpose of SSH_FXP_REALPATH.

debug3: SSH_FXP_REALPATH . -> /users/catoosa size 0

Invalid command.

The bank says the User's default directory exists and the User Profile has
authority to use it. I'm also told that directory is the User's Default so
I don't have to execute a Change Directory.

Any comments/suggestions would be greatly appreciated.

The Complete Debug Log is shown below. The URL and IP have been changed to
protect the innocent.
