I am trying to setup our servers to only allow logins with a public/private key pair. 2 of our machines have to have root login access with ssh and the rest, we will login as another account and su to root. I just started with this company and on their boxes which range from version 5.1 to 5.5, if I open up the firewall to allow ssh access from anywhere, I can ssh to root without a password. The only uncommented lines in the /etc/ssh/sshd_config are the following: [snip] I'm hoping that someone can lead me in the right direction as I can't figure this one out. If this was only one machine, I would assume that it might have been hacked, but this is all of their servers and VM's that will allow me to ssh to them without a login/password and get into root. Luckily, they have always had their (supposedly anyway) iptables set to only allow access from specific IP's.
