It is now up on Silverwraith.com, along with several other FreeBSD tuning papers by the author.

Once Windows machines drop in market shares, let’s hope people and companies will have less DoS attacks. The last Google attack seems to have been due to lots of BotNets around the world in the hand of just a few crackers. The solution is having more variety among OS around the world. Sort of 20% Windows, 20% FreeBSD, 20% OSX, 20% Linux, and 20% for the rest. Ok, let’s dream 😉 2004-09-01 8:55 pm What kind of nonsense is that? You don’t need to be a big company to be a DoS target. And how does Windows’ market share relate to DoS attacks? It MIGHT relate SLIGHTLY to DDoS attacks through worms, but that’s a whole other story. 2004-09-01 8:56 pm re:Sort of 20% Windows, 20% FreeBSD, 20% OSX, 20% Linux, and 20% for the rest.

You don’t need to be a big company to be a DoS target. well, if you were like most end users that have puny dial-up or low end DSL connections this document is also pretty useless as there is no way you will ever fit all that data down your pipe to start giving the CPU a problem… maybe that is what he was getting at? 2004-09-02 1:27 am You don’t need a big pipe to bring a machine to it’s knees. There are many attacks that can be quite successfull with as little as a 14.4Kbps modem. 2004-09-02 2:55 am re:You don’t need a big pipe to bring a machine to it’s knees. There are many attacks that can be quite successfull with as little as a 14.4Kbps modem. example please 2004-09-02 5:05 am A smurf attack is just one. See http://www.webopedia.com/TERM/S/smurf.html. There are many other. Try google’ing for low bandwidth DoS. There’s lots of info available on the subject. 2004-09-03 4:01 am Sure, all that stuff is technically a DoS but not the angle the article getting at.
