It shouldn't be too hard to patch

  /usr/src/crypto/openssh/sshd.c:server_accept_loop()

by adding code for per-IP truncated binary exponential backoff
algorithm just before forking a child once a connection is
accept(2)ed. It's strange that it hasn't already been done,
being such an obvious and useful addition. ;)
