How do I display the number of failed login attempts when a user logs in?
Hi,
I have a RHEL 6.2 machine.
I am required by a customer to display the number of failed login attempts to the users account upon his login.
Currently (by default) when the user logs in (SSH) he gets the "Last login: " with the date of the last login.
I could not find where this is configured and how (if at all possible) I can add the # of failed login attempts to the display.
Thanks in advance,
Itamar

Have you looked at pam_lastlog?
