Problem :
In /etc/securetty I commented out tty2 and tty3:
#tty2 #tty3
This succesfully disables root login for these two terminals for root.
But is it possible to display a message such as “root login is disabled in this terminal” if a login attempt is made?
Solution :
You can get the current terminal with the tty command, so you can put something like this in the user’s .bash_profile file:
if [ `tty` = "/dev/pts/0" ]
then
echo "......."
