Recertified for CCNP - ENCOR
CCNP - ENCOR ‘Recently’ Cisco changed the CCNP track quite a lot. In the past it was composed of vertical colums so to say with Routing, Switching and Tshoot as seperated colums. This had the advantage that you could focus on pure Routing and pure Switching and no need to worry about bringing many different knowledge into the exam. To recertify you needed to pass one of the colums to pass and extend the certification for another three years.
Clash of Clans Python Scripts
Introduction For years I have been playing ‘Clash of Clans’. A strategy game that requires you to actively engage with others in either direct battles, or group based battles. You can improve your village by leveling-up housing, spells, troops, the town hall, heroes, having boosters etc. Ofcourse the makers allow you to play for free, which can take quite some time to get progress, or you can buy additional resources and improvements that speed up the process.
Mailcow Grafana Dashboard
Introduction For a while now, my hosting company JR-Hosting, was stopped. But I still needed a way to host my mailboxes and that of several other domains that I own. It was brought to my attention that while playing with Docker I could combine that with a mailserver setup. Mailcow, or better Mailcow Dockerized. As there was a previous version which did not use Docker :-). The setup is trivial Installation link or at least it was for me.
Sue Student Edition 2021
Sue Student Edition 2021 Today my first Sue Student Edition happened. Well not entirely true, it happened a few times already and I was present most of the times. But today was somewhat special. I gave the keynote before my coworker Tijmen did a presentation + workshop. And I recapped the event afterwards. Digital edition As Covid is still around very much and restrictions are in place all over, we needed to host this event on our digital platform.
Emerging Threats Python script
Introduction For some time I am a perl fan, but perl is not that popular anymore so I decided to try and see whether I can use Python as well. After moving my systems from FreeBSD to Ubuntu and Debian (proxmox needs it) I also used the ‘emerging-ipset-update.pl’ script to drop emerging treats as soon as possible. Python After or rather while following the Udemy’s ‘2020 Complete Python bootcamp: From Zero to Hero’ by Jose Portilla (Hi!
The end of JR-Hosting
At the end of the month, my company JR-Webscripting en Hosting, will cease to exist. Justin and myself thought things over and with changes in our lives in the entire last year(s), we decided that we needed to spend our time differently. The time and effort of running your own business in the (flooded) hosting market is extremely difficult. You need scale, and offer an interesting price. And it will cost you countless hours.
In Memoriam Freddy Mercury 5-9-1946 - 24-11-1991
On my old blog, I tried to remember the passing of Freddy Mercury periodically. I failed to do that for several years. Freddy, wherever you may be, rest in peace. I still remember your music and listen to it very often. I visited the concerts of the remaining band members of Queen, it’s still amazing, even without you. One day, we will meet!

In Memoriam Paul Schenkeveld 1963-2015
A few years ago, I was informed that Paul Schenkeveld had passed away. That was very unpleasant news ofcourse. I knew Paul for some years, at the D-BUG or NLUUG BSD days he was one of the organisers and I was one of the speakers back then. In addition he was one of the main organisers of the 2011 EuroBSDCon in Maarssen. I always saw Paul.. and then Cor.. or the other way around.
NLUUG 2019 Najaarsconferentie
As the title states (in dutch sorry it’s the original name, but you can translate it to: autumn conference NLUUG2019), I was at the NLUUG 2019. My last visit with Snow (now Sue) was when it was still in “De Reehorst” in Ede. Which appeared to have been a few years ago. One of the reasons for not visiting it more often is that I was soo much into FreeBSD that I didn’t look around that much.
Aandacht voor de leraar
Voor Sue is het opleiden van onze mensen belangrijk. Wij zorgen er dan ook voor dat onze collega’s door ons (Fieldmanagers) bezocht worden, om zaken op technisch vlak maar ook opleidings vlak door te spreken en regelmatig te plannen waarmee en hoe iemand zich wil ontwikkelen. Vervolgens maken we dat als bedrijf mogelijk door opleidingen te faciliteren, studiedagen al contractueel beschikbaar te stellen, de kosten te betalen van de opleiding EN de certificering.
Migrated to Linux
If you would have asked me a few years ago, whether I was going to migrate my servers to Linux? I would have laughed and not even consider it. Since 2004 I have hosted all my own servers on the FreeBSD OS. I had one CentOS machine, because OpenXchange on FreeBSD was not the best experience. But now, in 2019, all my servers are running one of the Linux OS’es. Mainly Ubuntu.
Reponse zones in BIND (RPZ/Blocking unwanted traffic).
A while ago, my dear colleague Mattijs came with an interesting option in BIND. Response zones. One can create custom “zones” and enforce a policy on that. I never worked with it before, so I had no clue at all what to expect from it. Mattijs told me how to configure it (see below for an example) and offered to slave his RPZ policy-domains. All of a sudden I was no longer getting a lot of ADS/SPAM and other things.
