Ask SSH to give you some hints by
e.g.
$ ssh -v root@somehost

Hi Hermant,

If '/etc/securetty' exists, the devices listed in it are the only ones which will accept a root login. A common way to increase security of your system is to only allow root login from the console. This is accomplished by echoing 'console' to '/etc/securetty'.

If this is the case for your environment, and you are alright with the security ramifications of allowing root to login from any terminal, comment out ('#') 'console' from '/etc/securetty', or delete the file (if it contains no other entries).

Hey;

Spex, your comment is not accurate as it relates to ssh. The /etc/securetty only affects telnet and rlogin. ssh allows root access if so configured in sshd_config and ssh_config regardless of the contents of /etc/securetty.

As for the issue at hand: you should probably

grep -i permitrootlogin sshd_config

to ensure the parameter isn't reset somewhere else. Also check in ssh_config and ~/.ssh/config to see if anything is set in those files that might be causing it.

Failing those, as previously suggested, post the results of ssh -vvv ${target} so we can see the login process and provide some additional help.

I suggest to disable 'su to root possibility'
and install 'sudo' or something similar.

the sshd_config should have 'PermitRootLogin' set to yes. Some vendors have it as 'EnableRootLogin'.
