Guys,
I have linux box with yellow pages /etc/nsswitch.conf ....etc.
Everything works just fine.
Now, I would like to disable ALL logins except user PENGUIN
I put /etc/nologin, played with /etc/login.access, BUT no luck...
/etc/nologin - will disable ALL logins, BUT I would like to keep PENGUIN
(within yp of cource) off the list
Any input/ideas are welcome!
