If I use the 'who' command I can see that I have about 5 ttys running, some as far back as a month ago. Id like to be able to get rid of these ttys so I did a 'ps aux' looked up the pid #s and went to kill off these processes known as /sbin/mingetty (5 appeared) but they would just respawn. Why would these 5 ttys be running in the firt place? I always log out of the shell. How would I kill these ttys? And what is the need for the mingetty process?
