The "Aaron Blosser" Search Warrant
 
I have been reading the story about 'The "Aaron Blosser" Search Warrant' at [URL=http://www.tipjar.com/blosser/]http://www.tipjar.com/blosser/[/URL] about the unauthorized running of Prime95 on some corporate computers.

I realize that the story is about 5 years old, but I was curious about why Prim95 was loading the systems down so much. The current versions of Prime95 are some of the most benign programs you can run on your system. I have never seen it interfear with anything else I was doing.

Did the earlier Prime95 versions have a problem staying out of the way?

Recently he got back some of his equipment that had been seized.
He discusses the situation here:

AFAIK, he used to start a distribution from various NT workstations all around the country, with an automated script, but as he did not modify the "at" command, all the workstations tried to contact the server at the same time.

There was a peak in the use of the internal network, and the remained bandwith was not enough for the rest of the firm's services, blocking the work on it.

The manager of the firm asked Federal help, as he thought his network was under attack; it turned out that the network storm was provoked by a hundred stations contacting an extranet server, there the doubt of stolen information by an industrial spy.

On current hardware they definitly interfere with your power bill :grin:

I seem to remeber that it was [b]not[/b] prime95 that caused the problems, but coincidentaly, the (netwerk??) problems started shortely before (or after) Aaron started distributing the GIMPS client.

While investigating the problems they frequentely saw the primenet IP address comming by, and linked that to the problem.

I've got to read the argives again to get the exact story though.

No.

It wasn't.

Prime95 was a convenient scapegoat for problems that arose elsewhere.

The moral of the story in the tipjar.com article should have been
"Get written permission before installing idle-cycle software on any machines belonging to someone else, so that that software is not unjustly blamed for problems that arise elsewhere."

It would also be wise to document in some way the throughput of the systems before the idle-cycle software is installed.

And if you can bear the thought of the wasted cycles, don't install the software on a (small) random scattering of sytems. Periodic benchmarking would then catch any impact (or document the lack).

Re: Every machine contacting the server at the same time.
Rather than building master *.ini files and copying them onto new systems -- have the load script [B]write[/B] the ini files and incorporate the current time, or a base time plus the current minutes. Then most machine would have a unique schedule.
