I did try to use the documentation provided by John on How to use PPK for authentication to access SFTP/SSH bu it did not provide all the information needed to use the PPK. I also tried to use the credentials icg-user and PPK still not able to log-in in 11.141. After researching correct if I'm wrong on how this thing works. The user needs to generate a public/private key pair this will serve as a link between the user machine and the server that will access without using any password before you can do that the generated public/private key should be paste in the server as this will serve the pairing and with that, we need to have access to the server to paste the generated public/private key every time a user requested to access the same server. Let me know what you think as I just based this on what Jimmy provided the user only need to access the 11.141 window explorer and the documentation from John on how to use the PPK.
