Use a 486 SX processor that has only 8MB RAM available to it and a slow IDE disk (with enough swap). ;-). (Seriously. I have such a beast on my desk.) Alternatively, renice sshd so that it has lowest CPU priority and then run a bunch of other CPU-intensive processes. That should sufficiently starve sshd of CPU time so it can't compute the key stuff in a reasonable amount of time. -D -- "Open Source Software - Sometimes you get more than you paid for..." http://dman.ddts.net/~dman/
