I just ran rkhunter --check and all was good except this:

Checking if SSH root access is allowed                   [ Warning]

What does this warning mean? SSH root access is not allowed on this system.


Here is how my /etc/ssh/sshd_config is set:

PermitRootLogin no

and rkhunter.conf

root ~ # cat /etc/rkhunter.conf | grep  ALLOW_SSH_ROOT_USER

The following values need to match:

  1. In rkhunter configuration:

    cat /etc/rkhunter.conf | grep ALLOW_SSH_ROOT_USER
  2. In sshd configuration:

    cat /etc/ssh/sshd_config | grep PermitRootLogin
    PermitRootLogin no

Once they do match, you should not be warned by rkhunter any longer.

    Yes, thank you for the edit! Still getting used to the editor. – Joshua Lokken Apr 2 '15 at 20:47

In case you have set in your /etc/ssh/sshd_config

PermitRootLogin without-password

Again in the /etc/rkhunter.conf the value must match, as in the following example:

  • Everywhere I read, it is specified that (in case of Ubuntu), you should write: ALLOW_SSH_ROOT_USER=yes, but that doesn't work. This answer solves it! Thanks! – lepe Sep 9 '17 at 4:58
