Can't think of any trick aside from hacking the Linux TCP/IP stack, or adding a sleep(60) statement in the OpenSSH source right before it accepts connections ;-) More seriously, FreeBSD has a special network driver for faking broken network connections like this. No idea if Linux has anything similar, but I'm sure someone has tried something like this, somewhere... -rob
