How To Generate Let’s Encrypt Free Wildcard Certificate Using Certbot on Ubuntu 16.04

Let’s Encrypt has recently started supporting wildcard certificates using its new ACME2 protocol. This means that you can have a single wildcard certificate like *.asknetsec.com and use it on all the other sub-domains like blog.askenetsec.com, email.asknetsec.com.

This makes is very easy to manage certificates for different sub-domains. Until now each sub-domain needed its own certificate generated for the specific sub-domain.

nginx & Pyplate CMS

Last night while reading upon webservers (apache vs Nginx) and running a webserver on a Raspberry Pi (which i have at home) i found this website regarding rapsberry pi webservers which he runs on a cluster in his basement. Next to that he also have a cluster running on a Banana Pi (Chinese made Raspberry)

The writer/owner also made his own CMS (pyplate) in order to host static pages which makes Nginx really fast and stable while hosted in a cluster. I noticed this big online discussion on what is better, Apache or Nginx, but it all has its own benefits.

This made me decide not convert the VPS webserver to nginx but to keep it running apache and play around on the pi. After installing nginx a couple of weeks ago, i already had this basic html page running with a couple of shortcuts (here, my other blog, my owncloud) but after installing pyplate, did a quick look around and configured some pages (http://home.l4urenz.nl)

Whatpulse on Ubuntu, Part 1

When i bought my new laptop in Januari, i installed ubuntu 14.04 on my old one. This due to the fact that i just love my IBM T61 laptop.

Example picture of a T61

After a few week, i found out that i am working more and more on the T61 that on my new i5 windows machine. This had more reasons. first SSH sessions are way easier from a terminal instead of running a separate application like Putty. and when i just a fast machine to make my nas do something or search stuff on the web and want to have bigger screen then my Z1 experia. The ubuntu machine is quite fast.

So back to Whatpulse, I’ll explain more about whatpulse in a later post. but for a TL;DR; Its stats whoring with your keystrokes and a lot more data…

Installing was a issue due to the large number of packages you need, but the knowledge base on whatpulse.org was pretty straight forward and got it finally working. YAY!

ZNC bouncer for IRC

So when we ordered the VPN last tuesday, the prime objective was to have a IRC Bouncer working, so that it can reply the missed messages while my machine was offline.

After looking around, i found a few howto’s that use the ZNC software and eventually used the following article to configure everything.

So yay, happy chatting on Quakenet.org #NijNtje ^^ hows that for oldskool stuff
