Limiting Root login

[Andrew Moody_1]

I've inherited some systems (7410,5470,3440 etc etc) that seem to prevent you being able to telnet to and login as root. You can login as your own username and su to root but you can't login as root as the telnet prompt.

Any ideas how this has been achieved?

With thanks

Hi Andrew:

You may have an '/etc/securetty' file, then root is allowed to log in successfully only on the tty devices listed in this file. Commonly, the file contains only "console".

Regards!

Edit or create /etc/securetty and add this content,

/dev/console

Hi,

As mentioned above this is restricted through /etc/securetty. Either add the entry of tty where you wish root login or you can rename this file and root shall be allowed all over.

HTH,
