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.

    Actually, some of the humor in this RFC is that it mocks the futile 'consensus' basis of all the RFCs.

    Take it just a little bit serious and you say to yourself 'Wait a minute, this isn't that funny. People really do believe a consensus-based network will scale well worldwide....'

  3. Nmap compliance! by spydir31 · · Score: 2, Interesting

    There now exists a patch for nmap which sets the evil bit on by default, available here
    also, more discussion on when the evil bit should be set.

    Our military aren't under orders to shoot anything that moves.. They're given legitimate military targets.. Our soldiers always have the option of not shooting, if it doesn't seem like a valid target. They don't waste bullets shooting into empty shacks. They spend them on targets that are very potentially out to kill them.

    Like British tanks and buses full of unarmed women and children.

    I'm old enough to remember when discussions on Slashdot were well informed.

    Too bad the second BBC link doesn't have the full details clearly at the beginning of the story.

    The van drove up to the checkpoint. But rather than stopping or even slowing down, it continued at full speed through the checkpoint.

    If I was guarding a checkpoint, to make sure no one's driving a car bomb through, and they did the same manuver, I'd fire too.

    That's the easiest way to get a bomb through a checkpoint. Drive. Don't stop.

    Bin Laden did the same thing, except with airplanes full of men, women, and children. It was aparently easier than sneaking a bomb into the country.

  6. what about the "security" bit? by eirikma · · Score: 2, Interesting

    There used to be a "security" bit you could use to mark you packets as especially interesting (the do-not-route-thru-Iraq-bit) [rfc 791]. Is that feature obsoleted by this evil?
