I created a GitHub repository for Zabbix Templates

Two months ago I started a repository to upload and share some of my Zabbix templates. Of course they’re also listed on: 

Somehow I forgot to post about it on Twitter and my blog. But it’s never too late:

HowTo: Update Seafile Server for generic Linux to version 6.2.5 64bit

Seafile Server is an open source alternative to public cloud storage providers like Dropbox, Microsoft OneDrive, Apple iCloud, Google Drive and Citrix Sharefile. It works on free Linux Distributions like Debian and gives you the freedom to use the comfort of a modern synchronization client, the simplicity of a modern WebGUI, completed with the knowledge where your data is and who can access it.

Since 23.01.2017 the fifth maintenance release version 6.2.5 is public available.

Time to upgrade the server! 😀

How I build and maintain WSUS Server

There are hundreds of WSUS Server Tutorials available in the World Wild Web, and none of them fitted all my needs. I would never say that my way is the best way, but I spent quite some time with WSUS in the last few years and by now all of the servers I maintain work quite stable. (Except 2008, I hate Server 2008). 

First of all sorry for the German screenshots, but I thought better German screenshots than no article. The next time I setup a en-US WSUS I will swap the screenshots. 

Your best bet IMHO is to switch to Microsoft Windows Server 2016 asap. Server 2008 R2 won’t get Support for Windows 10 Feature Upgrades and Server 2012 R2 got it very delayed through an “interesting” hotfix. Windows Server 2016 seems to be the most reliable choice.
Second lesson I learned is, always install the Microsoft SQL Server Management Studio on the WSUS Server. You will need it sooner than later.
Third lesson is that WSUS will fail sooner or later, if you don’t execute a maintenance script on a regular basis.  Continue reading “How I build and maintain WSUS Server”
