Hi ,
I'm using SQL Developer 19.2.1.
I'm trying to figure out how I can use the SSH Hosts tool.
It looks like a sort of SFTP tool, only using SSH.
I've set up SSH links between these two hosts used in the below configuration just on our Linux boxes and got them to work.
I'm trying to figure out if this is the same thing and if you use it to move stuff between hosts using SQL Developer.
I set up the Local Forward like so:

and I set up the Remote Forward connection to get to one of our Linux boxes like the following:

I click on test connection and logged in to the remote Forward connection(?) with my server credentials and the test came back successful,
But when I try to connect I get this:

I'm just playing around with this stuff, but I'm trying to find out several things:
1. What do I need to do to set up my connection correctly?
2. How do I use the feature once configured correctly, Is there a display screen that comes up?
3. What do I need to do to fix this error message?
