I have been constanly asked to run a linux command on the server app01 but any attempt i made to switch to the server always prompted for the password which i don’t. hence, I could not move forward
This information is on the “Details of all Users and Server” page that’s linked in most KKE labs. To access a server, say, App Server 3, look it up in the table. For that server, to access it you’d do
ssh banner@stapp03
and use the password for banner listed in the table.
