Not sure. If I'm reading ttys(5) correctly though this is the section
``secure'' (if ``on'' is also specified) allows users with a uid of 0 to
login on this line. The flag ``dialin'' indicates that a tty
describes a dialin line, and ``network'' indicates that a tty
vides a network connection. Either of these strings may also
fied in the terminal type field. The string ``window='' may be
by a quoted command string which init(8) will execute before
command specified by the second field.
So I think that the following would be valid (but possibly dangerous
if you use other login daemons like rshd, sshd for logging in
remotely); that may be fixable with a firewall though and specific
rules to each daemon though.
In ttys (near bottom), instead of:
ttyp0 none network
ttyp0 none network on secure
and repeat for the rest of the ttys you wish to enable the option for.
Why not use root login with telnet or standard getty through serial
