Re: root can't login from tty but yes from console

Hi Manuales:

You appear to have an '/etc/securetty' file. This file, if present, lists the valid 'tty' devices for a root login. If you don't want to restrict root's login to the console, remove this file or add the 'tty' devices you need to it --- one device per line, like:

console
tty01
tty02

Regards!

Hi (again) Manuales:

In this case you may want to remove the 'securetty' file entirely, thus allowing root logins from anywhere.

Regards!
