Question

lastlog shows root login when login is disabled.

The ubuntu (20.0.4.2) command lastlog shows root has logged in two weeks ago. The passwd command shows root as locked as does getent root. /etc/ssh/sshd_config has “PermitRootLogin no” and “PasswordAuthentication no”

Should the logins reported by lastlog be a concern? They are from an ip address that cannot be identified by dig. Are the logins related to maintenance of the VM?

After digging around I realized the logins were during the initial build of the system.
