Example: Limiting the Number of Login Attempts for SSH and
Telnet Sessions
Limit the user four attempts when entering a password
while logging in through SSH or Telnet. Set the backoff-threshold to 2, the back-off-factor to 5 seconds, and the minimum-time to 40 seconds. The user experiences a delay of 5 seconds after the
second attempt to enter a correct password fails. After each subsequent
failed attempt, the delay increases by 5 seconds. After the fourth
and final failed attempt to enter a correct password, the user experiences
an additional 10-second delay, and the connection closes after a total
of 40 seconds.
