I have completed this task severally, but after submision it keeps failing. Please what am I doing wrong?
You’re doing the task on the wrong server, is the problem. As you see, you’re using the thor@jumphost server. You need to ssh into the “App Server 1” server. If you look at the “Details of All Servers and Users” link in the task screen, you’ll find that for App Server 1, you need to do something like:
ssh tony@stapp01
to get into that server. You’ll also need to use the tony account to switch to the root user for this task as well with sudo.
