More DoS problems!!

preface: i've never mentioned this, since it's not really relevant to anything i've posted, but i figure i should make note of it since i'm sure most folks aren't aware of it: i'm formally associated with forumgarden, in the sense that i'm one of the guys who manages the 'backend' - i built the server that forumgarden is hosted on, and run assorted services associated with this venture. i don't do much at all in the way of day to day management of the actual forum system however - i'm the nuts and bolts UNIX administrator, not a moderator. if you poke around you can find the connection - there's a link to Smile Networks on forumgarden's main page, and if you go there, and click on the 'about' link, you'll see my mug once again.
now, that said: this particular incident was likely not a DoS. there are other reasons that outages can occur - MANY reasons - and this one appears to be due to a flakey piece of hardware on our local network. We're going to replace the hardware soon (within about a week - we don't have a replacement on hand), and that should eliminate the problem.
As far as the assertion 'there are ways to prevent DoS attacks', there are ways to prevent *some* DoS attacks, but by no means is it possible to prevent all of them. that's fundamental to TCP/IP. if you want to accept connections from the net, you are vulnerable to DoS. period.
again, in this instance, it doesn't necessarily appear to have been a DoS. sorry about the outage, it's frustrating for us too!
