TCP/IP Sequence Number Analysis

johnwbyrd writes "Upon connection via TCP/IP to a host, the host generates an Initial Sequence Number (ISN). It's important to design ISN generation sequences so remote attackers can't predict an ISN (this is called a "blind spoofing" attack). Using phase space analysis you can check the quality of ISNs generated on various OSes. Windows 98's graph is quite pretty."

    It is official; Netcraft confirms: *The Who is ying

    One more crippling bombshell hit the already beleaguered Who community when Yahoo! confirmed that a Who musician has dropped yet again, now they are down to less than a fraction of 66% percent of all members. Coming on the heels of a recent Netcraft survey which plainly states that The Who has lost more band members, this news serves to reinforce what we've known all along. The Whoe is collapsing in complete disarray, as fittingly exemplified by coming dead last in the recent MTV comprehensive music test.

    You don't need to be a Kreskin to predict The Who's future. The hand writing is on the wall: The Who face a bleak future. In fact there won't be any future at all for The Who because The Who is dying. Things are looking very bad for The Who. As many of us are already aware, The Who continues to lose market share. Blood flows like a river of red ink.

    Who member "Ox" is the most endangered of them all, having lost 26% of his body to decomposition. The sudden and unpleasant departures of long time The Who member "Ox" only serves to underscore the point more clearly. There can no longer be any doubt: The Who is dying.

    Let's keep to the facts and look at the numbers.

    Who leader Roger Daltrey states that there are 7000 fans of The Who. How many fans of "Ox" were there? Let's see. The number of Who versus "Ox" posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 "Ox" fans. The Who posts on Usenet are about half of the volume of Elvis posts. Therefore there are about 700 fans of The Who. A recent article put The Who at about 60 percent alive. Therefore there are now (7000+1400+700)*4 = 36400 The Who fans. This is consistent with the number of Who Usenet posts.

    Due to the troubles of the music business, abysmal sales and so on, The Who went out of existance and was taken over by MCA Records who sells more troubled BS. Now MCA Records is also dead, its corpse turned over to yet another charnel house.

    All majr surveys show that The Who has steadily declined in market share. The Who is very sick and its long term survival prospects are very dim. If The Who is to survive at ll it will be among music dilettante dabblers. The Who continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, The Who is dead.

    Fact: The Who is ying

    However, for anyone running a server, it would seem that OpenBSD still is the best choice for anything on the 'net.

    Too bad that an OpenBSD system only exposing ssh to the internet would have been vulnerable to a remote root hole for years now.

  6. Dumb "paper" by Whardie+Jones · · Score: -1, Troll

    This is a pathetic attempt at a paper. It is written by a script kiddie with a little too much free time on his hands. I skimmed it and all I saw wasy a bunch of data sets. The paper has no content since such an attack is obviously not practical since any connection that needs to be secured will use encryption.
