But isn't there a DoS hole under Linux anyway? IIRC anybody who is
able to use all available memory (incl. swap) can bring the system down,
as the kernel will start to randomly shut down processes. That was true
for 2.0.x at least, I don't know whether that was fixed in the later
2.2.x or 2.3.x series - there was a lot of talk about it on the kernel
list once...
If I'm completely off target here, would someone please correct me? :-}

Thomas
