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.

    Great article, I think there's something in it for everyone. I recommend it thoroughly, a kind of laymans view of just what is possible.

  2. The "WTC" myth : come on ! by Anonymous Coward · · Score: -1, Offtopic

    It amazes me that so many allegedly "educated" people have allowed themselves to be so swiftly deluded by a fraudulent fabrication of such ridiculous proportions. The very idea that not one, but two jumbo jets would crash themselves into a famous New York skyscraper -- in broad daylight with vigilant air-traffic controllers and tight airport security watching every move of every craft in the air -- is laughable. Furthermore, it is a horrendous affront to the world-renowned intellect and common sense of the American people. The fact that anyone could actually believe this is evidence that the Liberals -- after decades of waging war against intellectual integrity and honesty -- have finally ripped the few remaining, tenuous strands of control of our educational system from full-blooded, hard-working, God-fearing Americans.

    As such wonderful documentaries as The Siege have so articulately exposed, the Liberal masterminds in Berkeley and their toadies throughout the nation have been silently waging war against the American people and their God-given rights to protect themselves, their worship, their family values, and their hard work. Much of this has been conducted under the guise of preventing "terrorism", a meaningless word engineered by radical left-wingers specifically to bring fear into the heart of honest Americans. Think about it -- can you remember any reference to so-called "terrorism" that occurred before Liberals invaded our government offices in the last decade? Of course you can't, because despite whatever the revisionist histories may tell you, there is no mention of any "terrorism" in classic literature before 1980. Only then did the neo-Marxists invent such absurd figures as Timothy McVeigh and Osama Bin Laden in order to legitimize their anti-freedom agenda, drowning the spirit of the American people in a blatantly-engineered machine of fear and mourning for "victims" of these "terrorist attacks".

    In fact, it should be incredibly obvious that the concept of a 110-story building even being built, much less two, is a clear and obvious fraud. No documentation of these "twin towers" existed before a "terrorist attack" occured on the previously-nonexistent pair of skyscrapers on September the 11th. Due to this hoax being perpetrated by the Liberal-controlled media, suddenly people all over the world mourned the loss of thousands of people who had not existed before. Innocent men and women, brainwashed by the left-wing education institutions, gave firsthand accounts of losing relatives they never had until the "attack" happened.

    But the most outrageous aspect of this hoax is the "Pentagon" -- a government office fabricated especially for this purpose. Liberal media claims this imaginary building to be "the center of America's defense system", although obviously an organization as proud and God-fearing as the United States Military would never think to station themselves in a building of five sides, so obviously close to the pentagram, mark of Lucifer himself. It is insulting to the nation's intelligence that eight hundred members of the world's proudest institution would be made to meet their Lord by something as graceful, efficient, and secure as our country's fine aviation system.

    Don't let the devious tricks of the Liberals allow you, a citizen of the greatest nation this Earth has ever or will ever know, to surrender your freedoms. Any lesser nation would have succumbed to their wills long ago, and indeed the socialist states in Europe already have. It is only the superior resilience, pride, and intellect of America that has allowed it to withstand the constant threat of Liberal control.

    It has come to my attention that "slashdot", subsidiary of VA Software, is a refuge for people with a terrible sense for grammar and spelling. As a remediation, please accept the following recommendations about the use of some frequent linguistic expressions :
    • "Alot" vs. "A lot" : There is no such word as alot. In fact, when confronted with the word alot, ispell tells us the following : "how about : allot,aloe,aloft, alto, blot, clot, lot, plot, slot"
    • Just the fact moronic Americans pronounce Bernstein, neither, Einstein and other 'ei'-words as "Burnstean", "neather", "Ainstean", etc... doesn't mean they have to write those words "Bernstien", "niether" or "Einstien". Special mention to "thier", "becuase" and "amatuer".
    • "Than" vs. "Then" : Just the fact that in some inferior dialects of the English language, "than" and "then" are pronounced about the same way doesn't mean that the comparative "than" has any reason to be written as the conjunctive/logical "then".
    • Your vs. You're : The former means "not my, not his, not our", in other words it is a possessive. The latter is a shortcut for "You are". Similar point for There vs Their vs They're.
    • Hobbyist and lobbyist are not superlatives. Hence they musn't be written as hobbiest and lobbiest.
    • Thi fuct thit ya ridnucks prunince any avelible vowal as "uh" doesn't forbid you to open a book from time to time to actually build up some vocabulary. It's "ludicrous" and "compatible", not "ludacris" and "compatable".
    • Its vs It's. The former is the genitive form of "It" and will therefore make the following word an attribute of the word replaced by the pronoun. Example : illiteracy and its consequences. The latter is an shortcut for "It is". Example : Illiteracy. It's so annoying.
    • lose vs. loose : the first is the verb associated with a loss. The second is the contrary of "firm"
    • to vs too : Your spelling is too pathetic for your post to matter to me. The same goes forour grammar too.
    • I could (not) care less. Most people say "I could care less" when they don't give a flying fuck. If they really could care less, then their lack of interest isn't that big. What they mean is that they could not care less.
    ...many more to come. Reply to this comment to suggest some.

    A bunch of computer nerds without a sense for spelling and grammar mocking japanese game translators for their lack of skills in english spelling and grammar.

    Contribution by Erpo :
    I'm not any kind of grammar nazi, but decent spelling and grammar are important to me. The occasional affect/effect problem doesn't bother me (it just lowers my opinion of the author), but when a piece is riddled with errors (there/they're/their, its/it's, then/than, etc..) it's hard for me to read. Partially, I think this is because I sight read and I don't subvocalize. In other words, when I see, "It's over their," in print the first thing I think is, "It's over their what? Is it hovering over their kitchen counter? Is it over their heads? What is this person trying to say?" Of course, I don't just sit there pondering those questions (it only takes a split second to see there was a grammar error in the sentence), but I can't read as quickly when every few lines my eyes flick back to an earlier word.

    Maybe I'm just hypersensitive. I don't know. If you don't know what I'm talking about though, check out this piece by Prince. It doesn't have very many grammar problems, but the "creative" spelling is really distracting.
