    Very strange is this; reported BEFORE it happened?

    I see they have been playing this DDos Attack in the press. In fact, as near as I can tell, the stories about this ddos attack started appearing very early on. Most companies take some time to discover they have a ddos attack, and then to take the time to report it; the press also has lead time for a story to actually make it out the door and into print/web site/whatever.

    The early and timely appearing of their "press" about it even while this attack was "underway", and through so many sources, leads me to ask this question; is it possible they contacted any press BEFORE this alledged attack even took place?!

It is in fact possible for a class C subnet (254 addresses) to have 127 hosts(workstations) and 127 routers on the same subnet. In this bizarre and highly unlikely scenario, each of the 127 hosts could have its own unique, personal gateway.

You can look out, and pull data in from outside, but you don't let anyone straight in. Anything outside comes through another server - email to a mail server, or submitted to a webpage, like a GROKLAW post. These act as control points - outside the citadel.

Most of them rely on the link being saturated or the IP stack being so overwhelmed by bandwidth that it just quits responding or the packets never get to the machine.

    Think about it, first of all SCO has no motive to engage in any kind of DoS attack against themselves. Even if this attack would reflect badly on the open source community (instead of making them look like robin hood) SCOs fate rests entierly at trial. Moreover IF SCO had decided to lie about an attack they wouldn't have made it a *succesfull* attack. They would have just issued a press release saying they were the target of a DDoS but their software/whatever prevented any damage. Even disregarding this if this was a hoax of their own making why would it last so long.

    At the end of the day SCO still wants the software it is running to seem technically good. After all if no one is using linux who pays royalties? Faking this kind of attack is simply against their interest.

    Could it have been an ordinary fuck-up that they claim was a DDoS? Well certainly, however given the fact that other systems on their net were working fine I find it tough to swallow the sysadmins couldn't just switch to another server (unless they were protesting SCOs legal attacks).

    So while it is a *possibility* that SCO just had a network glitch we have no more reason to believe they are lying about the DDoS than when any other company claims to be such a victim. In fact as SCO is more likely to be such a victim (given the anger it has stirred up) their claim of a DDoS is even more reasonable than that of a generic company.
