Hello everyone !
1) Can anyone tell me what shall I change to restrict remote logins? Like
allowing only direct access via console?

2) How can I restrict number of terminals per computer? For example I want
to have only ttyE1 & ttyE2?

3) How would I hide OS information on terminal screen when you reach login
prompt?
For example NetBSD/i386 (VORTEX2001) (ttyE2)
login:

 but I want to see:

This Machine Is for Testing Only:
login:

How would I change that?

Thanks everyone,
And Have a Great Day !
