Alles, was irgendwie mit Administration zu tun hat
Recently, I wanted to add single sign on (SSO) functionality to our intranet server, which runs a Debian Linux. Users should be automatically logged in to the website using their Windows user accounts, which are stored in an Active Directory on a Windows Server 2008 R2, without entering their credentials…
A colleague of mine had a problem with a Windows Server 2008 R2 today: After configuring the server as the DNS server for the local domain, name resolution on a Debian client was extremely slow. A ping returned the correct IP and only took a few milliseconds but between each…
This article shows how to configure the Apache webserver and a PHP website to optionally use NTLM authentication (Integrated Windows Authentication) to authenticate the website’s users. That means, a user may log in via his or her Windows account but does not have to. If he cannot be logged on…
During the last few weeks I interviewed quite a few candidates for the position as a system administrator in our company (job ad here). But what questions do you ask a prospective administrator to check whether he or she has the needed skills for the job? We needed someone who…

Instead of uninstalling them manually I wrote the following short PowerShell script UninstallOffice.ps1…
Our WSUS server provided my computer with Microsoft Windows Update KB968930 (Windows Management Framework and PowerShell 2.0) but it could not be installed (without giving any helpful error message). After searching the web for quite some time, I found this solution to be working in my case: Deinstall PowerShell 1.0:…
Heute hatte ich die Aufgabe, mit einem Script aus einem Ordner alle Dateien außer die 10 neuesten zu löschen. Kein Problem für die PowerShell: $allFiles = dir *.* | ? { -not $_.PSIsContainer } | sort LastWriteTime -descending $keepFiles = $allFiles | select -first 10 $allFiles | ? { $keepFiles…
Unsere neuen Notebooks wurden mit UMTS-Sticks von Vodafone (Modell K3715) ausgestattet, was im Vergleich zu den vorher genutzten PCMCIA-Karten eine deutliche Verbesserung darstellt (z.B. ist die Treibersoftware direkt auf dem USB-Stick enthalten). Allerdings gab es ein Problem: die Einwahl vor der Windows-Anmeldung funktionierte nicht. Hintergrund: Wir nutzen den SecureClient von…
