Vorläufiges Fazit zu RootNerds
Der aktuelle Stand ist, daß man die VPS komplett neu aufgesetzt hat. Alle Daten sind – zumindest vorläufig – scheinbar weg. Interessant, daß man bei der IAMONSYS GmbH meint daß bei einem Problem welches so kraß ist und sich seit … Continue reading

Cheeky and stupid bot …
The bot with user agent Linguee Bot (http://www.linguee.com/bot; bot@linguee.com) just downloaded approximately 2 GiB of stuff from a ViewVC-listing on one of my servers. Just because it’s stupid, but also because it’s so cheeky to ignore robots.txt. So be it. … Continue reading

Have you ever noticed that oftentimes people in anglophone forums will almost be offended if someone quotes an error message in their local language? Well, on one hand I can understand it, on the other I see more value in … Continue reading
A shout to VMware …
Since I don’t have a support contract, perhaps you would be so kind to tell your setup authoring folks to not remove the last resort for anyone who tries to install the vSphere client 5.0? Thank you in advance, very … Continue reading

First impression of Windows Server 2012
*facepalm* // Oliver PS: does MS think that making it look like a 2D game and forcing everyone to click tiles instead of using the keyboard to navigate the startmenu makes an admin more productive?
SSL error with a newly signed cert?
Last night I literally spent hours figuring out an alleged issue with the certificate from StartCom. Of course the problem was entirely on my end, in the editor to be precise. But what happened? I fetched ca-bundle.pem and entered it … Continue reading
Highly useful: ddrutility
During a rescue mission I encountered read errors on both hard drives of a degraded RAID. Since most commercial end-user tools limit your flexibility I went for Ubuntu Rescue Remix 12.04 in order to use ddrescue. However, to my delight … Continue reading

Symbolic links to remote locations …
Recently after migrating to Windows 7 on my work machine, I ran into a little issue. I created symbolic links pointing to a network share. Now this is all fine and dandy, but symbolic links can only be created by … Continue reading

prune-kernels function …
If you are like me, you will have noticed on Ubuntu (and sometimes Debian) that stale old kernels remain on the disk even when they aren’t needed anymore. I wrote a little Bash function to get rid of those kernels. … Continue reading

Design and misdesign
So I did it. Ordered an iPad2 (despite the knowledge that the 3rd generation will hit the market soon). And what shall I say? Crap so far. Trying to get this thing to work with the WLAN router at my … Continue reading
Re: Oracle bought ksplice … and apparently the source was pulled
I contacted one of the good people from ksplice (I’ve got an active subscription) and got pointed to oss.oracle.com/ksplice/software/ Unfortunately the access to a distributed version control is gone for good, it seems.

Greylisting works amazingly well for me …
Yesterday I wrote a short comment about the Spamhouse case. Spamhouse is indeed very important as an antispam blacklist. However, for my server I can only state that since I moved to it (previously my domains were hosted together with … Continue reading
