Hi, I need some help to clarify TTY and virtual consoles. Thanks a lot.
1. I learned that to switch from one TTY to another, one must be at the physical machine. Does the same apply to virtual consoles? 2. My /etc/inittab includes the following. Does that mean there's only one instance of TTY on my CentOS?
... # Run gettys in standard runlevels co:2345:respawn:/sbin/agetty xvc0 9600 vt100-nav #1:2345:respawn:/sbin/mingetty tty1 #2:2345:respawn:/sbin/mingetty tty2 #3:2345:respawn:/sbin/mingetty tty3 #4:2345:respawn:/sbin/mingetty tty4 #5:2345:respawn:/sbin/mingetty tty5 #6:2345:respawn:/sbin/mingetty tty6
3. My CentOS was installed with Base option only. (This should be the minimum.) I don't plan to use any GUI stuff, and I always connect to my CentOS server using SSH. In this case, do I still need virtual consoles and TTYs defined in /etc/securetty? 4. What does "console" mean in /etc/securetty?
