Well... Imagine me wanting to crack your machine. So I'll sit on same subnet, and make it crash. (Crash is easier than crack ;-). I'll make your machine load shadow into memory. And then, I'll just listen.

PS: But yes, in case we really need coredumps, this is probably the good way to do it. PS/2: If someone is interested, I've patch for magic sysrq keys to work over network, including dmesg-like dump. -- I'm really pavel@atrey.karlin.mff.cuni.cz. Pavel Look at http://atrey.karlin.mff.cuni.cz/~pavel/ ;-).
