Thanks for your post. Very interesting to see all this. Especially
the summary on what the
Note i was quite amazed that you mentionned Rocks distribution
getting used with you.
A few weeks ago i grabbed latest Rocks with the idea to install it
for my 1 node cluster.
Both attempted with and without quadrics QM400 card.
Node being a dual opteron dual core 2.4ghz, tyan S2881 motherboard.
All i tried, it didn't help; the distribution crashed during
somewhere always. Very weird.
From all distributions i tried over a period of a few weeks install
at that machine,
it was the only distribution that crashed each time somewhere,
usually after checking the NIC's (which were not connected
to any network, let alone the internet). Sometimes also later on in
seemed to me the provided kernel in that distribution DVD to be not
very good one at all.
Now you post here a big story on how your Rocks got hacked. Do i
conclude it correctly the
problem is that you ran a default Rocks kernel?
I'd say: Go take a stand on the Rocks :)
Note in my case the only other problem it possibly could've been i
guess is that a bunch of
insecure encrypted drives are in the box.
p.s. the hacker seems to me from your description some sort of guy
with a criminal record.
Criminal as in: the type that goes into jail regurarly, so not the
Perry E Metzger type :)
Note he wouldn't be able to do that anyway as he just runs a few
but well, what the hell do i know there.
