    Repeated offenses by the same client address will accrue greater
    penalties, up to a configurable maximum. A PerSourcePenaltyExemptList
    option allows certain address ranges to be exempt from all penalties.

    attackers to find accounts with weak/guessable passwords or exploit
    bugs in sshd(8) itself.
