Windows 10 forced update sucks

Posted on 2018-02-12 by Oliver

I have written about Windows 10 before. Also about Windows 8.1, which is the predecessor in (diabolic) spirit. I was never impressed by Windows 10 and I guess it’s not going to change. Sure, Windows 10 has a very stable … Continue reading →

Performance hog extraordinaire …

Posted on 2018-01-23 by Oliver

So as of recently I started having issues with memory use. My machine has 32 GiB of physical RAM, so there shouldn’t usually be a problem running even several virtual machines at once. I’ve even run an XP VM from … Continue reading →

SSH reverse tunnel

Posted on 2017-02-23 by Oliver

With autossh you can establish an SSH reverse tunnel from a given system, provided it can reach some other machine via SSH outside its own network. You can also do that with ssh alone, but autossh comes with added features … Continue reading →

Vorläufiges Fazit zu RootNerds

Posted on 2016-01-19 by Oliver

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 →

Signing an RPM unattended …

Posted on 2013-09-04 by Oliver

It appears that there is no way to sign an RPM package unattended with the default tools. However, expect comes to the rescue. I found two descriptions on other blogs how to do it: from 2008 here: GPG signing RPMs … Continue reading →

Cheeky and stupid bot …

Posted on 2013-02-28 by Oliver

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 →

Posted on 2013-02-19 by Oliver

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 …

Posted on 2012-12-19 by Oliver

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

Posted on 2012-12-10 by Oliver

*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?

Posted on 2012-09-20 by Oliver

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

Posted on 2012-09-10 by Oliver

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 →

Posted on 2012-05-24 by Oliver

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 …

Posted on 2012-02-22 by Oliver

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

Posted on 2012-01-19 by Oliver

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

Posted on 2011-11-07 by Oliver

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.

FLOSS not sustainable for companies?

Posted on 2011-10-25 by Oliver

A few weeks ago I reported about ksplice whose Git repository had disappeared. Now the same happened for Likewise Open which was bought by BeyondTrust. After renaming the repository and moving its location from git://git.likewiseopen.org/likewise-open.git to git://git.likewiseopen.org/bt-identity-open.git it now also … Continue reading →

Greylisting works amazingly well for me …
