The system clock running backwards…

May 10, 2007

While reading this mail written to the XEN – Users – List (virtualization on linux):

” I’m using a NetBSD 3.1 dom0 with Xen 2.0.7 (so far as I know, the latest
supported combination for the NetBSD platform).

Linux domUs have their logs fill with messages like this:

May 8 02:01:39 debian kernel: Timer ISR: Time went backwards: -316000
131542680000000 9684000 131542690000000
May 8 02:01:39 debian kernel: Timer ISR: Time went backwards: -277000
131542680000000 9723000 131542690000000

They come in different amounts, sometimes a handful, sometimes hundreds.
Over the space of a day or two, the logs swell to gigantic sizes.

I have been googling this for a while and it seems like I am the only
person in the universe to experience this after 2005. So apparently time
really has gone backwards – about two years’ worth.”

Now, i`d become REALLY worried, if some system would be doing that…

Remember the famous ‘Vaxorcist’ – tale?
Perhaps seen the ‘the exorcist’ – movies?

Wondering about systems becoming … strange?

Then this is for you :)

And I really sometimes wish for a bucket of holy-water when trying to figure out why a Windows server does ‘strange things’…

grimm fairy tales – the intro and index

May 3, 2007

When I started to become an (unix) admin nearly 10 years ago (on a quite important DEC-OSF System that then switched from terminals to VT420 Telnet Emulation), i once stumbled about an document that became quite important to me: the Unix Admin Horror Stories.

These stories had a great impact on me: they are real, funny, and each contains a very usefull lesson to learn.

Nearly everyone of these lessons still applies today one way or another – be it a unix/linux/windows or mac installation.

Since then I`m looking for and collecting more of such stories – my finds will be posted here.

Comments are very appreciated (even a ‘yeah, me too :) ‘ .

Have fun reading!

The cat and the bag: ‘spread this number’

May 1, 2007

12.05.07 – UPDATE:

and an article on forbes:

01.05.2007

What happened this night was quite amazing: one of the master keys to decrypt HD-DVD`s got posted on digg.

Ok, the key was aviable for quite a while then, since february this year, but now it got some serious publicity.

Around 11 hours later, the article had been ‘dugg’ ~13.000 times – before it was deleted.

01.05.2007: a copy of the article on digg and the comments upo to the 12250 digg can be downloaded here:

02.05.2007: a copy of the new ‘spread the number’ article AFTER Kevin has decided to let it run – again, at 5240+ diggs.

The plain html – document (no graphics etc.) is provided for documentation purposes only.


At some times, the ‘digging-rate’ appeared to be like 5 per second – and at one point forced the digg server to deliver a 404 – not found (http://mirror.longhornlive.net/crazy404.png , by gcnaddict)

14 more diggs…
*blink*
19 more diggs…
*blink*
Whoa. (elmedico27)

Now the article is gone and also unaviable via duggmirror, but several screens of the amazing event still exist:

There were numerous other attempts to spread the word, in case of wikipedia leading to a little skirmish with the editors:

Other poeple looked into the ‘practical part’ as well:

while others went for some creative work:

All in all: it was quite an amazing event :)

If you have more links, screenshots, creative artwork, please use the comment function :)

EDIT: at 19:05 EST the digg crew disabled my digg account because of ‘misuse’. the only thing i did was to post a link to this short docu and a request for help in documentating this little incident. Seems like digg wishes it never happened, since all other references to the ‘spread the number’ post have been deleted as well. Even http://duggmirror.com/linux_unix/Spread_this_number_Now is gone and the google cache scraped.

EDIT 2: Every article that people try to get into digg with references to the ‘spread the number’ is deleted quite fast – the last post i`ve seen survived ~20minutes.

Luckily, i saved ‘spread the number’ having 12250 diggs :)

This one might shed some light on ‘official reactions’ :

And yes, the key WAS posted in the takedown notice. :)

Update on 02.05.07

Digg has blocked this site.

A german news magazin covers the ‘digg-revolt’ here:

And here is what the original poster wrote about this ‘little incident’:

and because nothing is right without having heared the other side, here is

the post by Kevin Rose from Digg.com

which i need to cite in full:

 

Digg This: 09-f9-11-02-9d-74-e3-5b-d8-41-56-c5-63-56-88-c0

Today was an insane day. And as the founder of Digg, I just wanted to post my thoughts…

In building and shaping the site I’ve always tried to stay as hands on as possible. We’ve always given site moderation (digging/burying) power to the community. Occasionally we step in to remove stories that violate our terms of use (eg. linking to pornography, illegal downloads, racial hate sites, etc.). So today was a difficult day for us. We had to decide whether to remove stories containing a single code based on a cease and desist declaration. We had to make a call, and in our desire to avoid a scenario where Digg would be interrupted or shut down, we decided to comply and remove the stories with the code.

But now, after seeing hundreds of stories and reading thousands of comments, you’ve made it clear. You’d rather see Digg go down fighting than bow down to a bigger company. We hear you, and effective immediately we won’t delete stories or comments containing the code and will deal with whatever the consequences might be.

If we lose, then what the hell, at least we died trying.

Digg on,

Kevin

It`s a pitty that a company can get in danger because of something that has been publicly aviable for mor than a couple weeks.I think that all those guys who posted the ‘code’ or in other ways helped to spread it yesterday will ‘breake out the guns and ammo’ again once digg is in danger (myself included, even though i only got a leaking waterpistol :) .

Point is : what would we actually do then?

Supressing the spread of the ‘key’ is imho an perfect example for attempted information control – and it`s failing, at least here and now.

At the same time, cryptome.org got it`s contract with the isp verio cancelled… another example of information control at work? You bet!

But so far, we have won:

Thank you, Kevin Rose!

07.05.07 Update

With the famous userfriendly.org – Cartoon by Illiad featuring a ‘HD-DV D Sudoku’ in yesterdays strip, there isn`t much left to be said about recieving Cease-adn-desist – letters :)
