Graphing Randomness in TCP Initial Sequence Numbers

Saint Aardvark writes "This is neat: Graphic visualization of how random TCP Initial Sequence Numbers really are for different OSs. It's a great way of seeing how secure a TCP stack really is. Cisco IOS is great; OS9, OpenVMS and IRIX aren't. Posted to the ever-lovin' BugTraq mailing list." This is a follow-up to the previous report.

    He must be running a server with no tcp stack. heh.

    It is a well known fact that all known existing hackers are 3-dimensional.

    Usually, those 3 dimensions are stretched to the limit, but there's still only 3 of them.

  3. New TCP/IP flags by Tinfoil · · Score: 5, Funny

    I propose a new flag in the standard TCP/IP packet. We shall call this the Slashdot Flag. The general purpose of this flag is to state whether or not the bandwidth limits of the server can handle the requirements a Slashdot posting can impose. If the flag is set false, Slashcode will automatically generate numerous, random, 'this page has been slashdotted' posts requesting a link to a mirror.

    That being said, the page *is* finally loading up so I'm going to go look at some pictures now.

    Not being well versed in statistics and math in general, I was struck by the resemblance of some of these pictures to images that i've seen of far off galaxy's and star clusters. Could it be that we live in a very high resolution of a randomness graph from some other universe???

    It's just a 133mhz netbsd box (...)

    Gosh, what all those years of slashdot have done to me? I actually read "It's just a leemhz netbsd box" once or twice before turning off my automatic l337 translator.

    I need to get out more ...

    Actually, getting true randomness isn't necessary. All you need is unpredictability and unrepeatability.
