On my Ubuntu Linux machine I can do this by editing /etc/securetty and commenting out all entries except for tty1 through tty8.


**EDIT - Sorry, I didn't realise this was in the SCO section, maybe someone should delete my post. Apologies.

For SCO UnixWare 7.1.x, you need to add the following line to /etc/default/login:

CONSOLE=/dev/console

This ensures that root can only login locally from the console. You must 'su' to root via telnet.
