Issue/Introduction

We have set up the autosys agent for to act as an FTP server.
We have enabled SSL for the client and Server certificate.
We can do user /password authentication ok.

But we would like to set up Key Pair authentication.
How can this be done?

Environment

Autosys 12.x

Systemagent

Cause

The agent does not support the SFTP protocol only the FTP protocol or FTP over SSL.

Resolution

The Autosys agent uses the FTP protocol and you can enable FTP over SSL.
However, the agent does not SFTP which is a different protocol.

The FTP protocol does not support Key Pair authentication, this if a function of the SFTP protocol.
