Icinga 2 and Icinga Web 2 on Debian 9 – Installation

If you’re following along, we’re completely ready and fully prepared for the Icinga 2 software installation. After today we’ll have a working interface and can start adding clients. When you’ve read the documentation, you’ll have learned that Icinga-wise there are masters, satellites and clients. Having all 3 is essential in large distributed setups. For my…

Debian DirectAdmin installation – Software

After a short intro and getting the quotas ready, we can install the DirectAdmin software. Installing the DA software is also pretty straightforward. You need a lot of dependencies and a lot of time though, because installation, and every DA update, takes a long time in comparison with many other Linux software. DA needs a…

Debian DirectAdmin installation – Quotas

Quotas are not enabled by default on Debian nor on DirectAdmin, but the latter needs it or else errors are flying all over the place. Fortunately it is not hard to setup. First we’ll take a closer look at your fstab file, I’ll do a quick rerun of an earlier post in this regards. Then…

Debian DirectAdmin installation – Intro

Although a VPS or an AWS instance doesn’t cost shit nowadays, some people still want to share a webserver. In comes DirectAdmin and this intro. There are more alternatives to DirectAdmin (DA), like ISPManager and Virtualmin, but DA seems to be the most used piece of software and most widely accepted. I absolutely hate it,…

Complete Nextcloud 12 installation on CentOS 7.4

OK, so here’s the deal. I had ownCloud up and running and was rather happy with it. I’d chosen ownCloud because I knew it from a few years back when I was looking for a Dropbox alternative for a customer. Never heard about Nextcloud before… A few days after this installation, a few sync problems…

Installing VMWare Workstation Pro 12.5.7 on Fedora 26

I’ve recently switched from Kali Linux to Fedora for different reasons. With the switch I wanted to give Virtualbox a try instead of the commercial VMWare Workstation Pro. Unfortunately, VirtualBox 5.1.28 on Fedora 26 is slow as hell (I believe it got something to do with the extension pack) and after half a day of…

Updating Zimbra from 8.7.4 GA to 8.7.10 GA

For about two months I had a couple of TO DOs regarding Zimbra and my CentOS 7 server. Yesterday I finally decided it was time to tie up some loose ends and make some long term decisions regarding my server. I’ll come back to these decisions later. For now: updating from version 8.7.4 GA to…

Kali setup things / Bluetooth / Printing

Continuing from my last post I log into Kali and started copying stuff from my backup drive to my home folder. This is about 300 GB worth of data so it takes a while. Halfway through though it strikes me: I’m logged in as root! Damn it. This is the first desktop/laptop Linux installation I’ve…

Kali Linux installation quirks

At first Kali was a bit overwhelming. During installation and also after installation. I really had a couple of difficulties during installation, which I was luckily able to solve. Also, of course I made a few good backups before getting to this. I like a good challenge but along the way it seemed it might…

Kali Linux

To get the best of both worlds into my certification path, I’ve installed Kali Linux yesterday. It’s Linux (obviously) and it is the suite to have when you want to do some penetration testing and (ethical) hacking. What everybody warns about, you should consider very well. Kali is not an typical end user operating system….

CentOS 7 – Zimbra 8.7.4_GA installation

A while ago I’ve installed the community edition of the Zimbra Collaboration suite. With a little hesitation to be honest since there where a lot of other candidates as well, I already wrote about it here. This was the short list: Kopano (formerly Zarafa), Axigen, iRedMail, Icewarp, Zentyal (bummer that this one only operates at…
