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.
We hope these options will make it significantly more difficult for
attackers to find accounts with weak/guessable passwords or exploit
bugs in sshd(8) itself.
Tell me in the old days there were other things that could happen. Like feathering somebody after tar pitting. I dont know what that would've meant. Maybe servers ridiculing an attacker or something.
Tar pitting sounds way more fun than rate limiting >.>
