RFC 3514: New Bit Defined for IPv4 Headers

Posted by jamie on from the SHOULD dept.

RFC 3514 was just released, with a new bit definition for use in the headers of IP packets. Because there are important security implications, anyone coding internet services (on either the client or server end) should probably take a look.

    The bit set to 1 indicates a pr0n site, the bit set to 0 indicates a non-pr0n site.

  8. Why computers crash, by Dr. Seuss by Mattygfunk1 · · Score: 4, Funny
    If a packet hits a pocket on a socket on a port, and the bus is interrupted at a very last resort, and the access of the memory makes your floppy disk abort, then the socket packet pocket has an error to report.

    If your cursor finds a menu item followed by a dash, and the double-clicking icon puts your Window in the trash, and your data is corrupted 'cause the index doesn't hash, then your situation's hopeless and your system's gonna crash!!

    If the label on the cable on the table at your house says the network is connected to the button on your mouse, but your packets want to tunnel to another protocol that's repeatedly rejected by the printer down the hall, and your screen is all distorted by the side effects of gauss, so your icons in the window are as wavy as a souse; then you may as well reboot and go out with a bang, 'cuz sure as I'm a poet, the sucker's gonna hang!

    When the copy of your floppy's getting sloppy in the disk, and the macro code instructions cause unnecessary risk, then you'll have to flash the memory and you'll want to RAM your ROM. Quick, turn off the computer and be sure to tell your Mom!

    ...it's 4/1 already...

    I liked this bit (emphasis mine):

    0x0 If the bit is set to 0, the packet has no evil intent. Hosts,
    network elements, etc., SHOULD assume that the packet is
    harmless, and SHOULD NOT take any defensive measures. (We note
    that this part of the spec is already implemented by many common
    desktop operating systems.    )

    0x1 If the bit is set to 1, the packet has evil intent. Secure
    systems SHOULD try to defend themselves against such packets.
    Insecure systems MAY chose to crash, be penetrated, etc.

    Actually I think somebody famous* established long time ago that sex, as strange as some of its involved rituals may seem to many at times, are a better alternative to war.

    I propose that instead anything coming from or going to a .gov extension has the eBit** set.

    I'm not being a spoilsport, but after a few years April Fools Day jokes start to seem a little formulaic and predictable.

    Well, ya they are predictable, they come every April 1....:)

    Perhaps if they just did a few random hoaxes a year, at different times, it would be a little more fun. As it is, its kind of like acting suprised when you get socks for christmas. And just as gratifying.
