I'm running Ubuntu 16.04 with a plain-vanilla install. The server is on a rack in the server room, and I don't have physical access to it. Fortunately openssh was installed on the machine.
Today, I have to install stuff on it, but the only account on the server is the default account ('admin'), and it appears that I'm unable to SSH into the box using the default account because of the ssh config file.
I was able to get someone to go into the server room and add an unpriviliged user ('scott'). I am able to SSH in as this user, but I can't figure out how to get root access.
I tried:
su rootand get Authetication Failuresu adminand get No passwd entry for user 'admin'sudo moduser -aG scottand get scott is not in the sudoers file. This incident will be reported.ssh admin@localhostand get Permission denied, please try again.
Any advice?
