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.
FreeBSD: Using Open-Xchange on FreeBSD
If you go looking for a usable webmail application, then you might end up with Open-Xchange (OX for short). Some larger ISP’s are using OX as their webmail application for customers. It has a multitude of options available, using multiple email accounts, caldav/carddav included (not externally (yet?)) etc. There are commercial options available for these ISP’s, but also for smaller resellers etc. But, there is also the community edition available. Which is the installation you can run for free on your machine(s).
The epic spam battle from SpamAssassin (10 + year user) to rspamd.
For many System Administrators that have public facing Mailservers, it is an ongoing battle.. SPAM. Since there is money to make, it will never ever go away, but we can try to mitigate this. Introduction on my usage of anti-spam products: For many moons I have used the SpamAssassin product in various forms, simply as a client to check every email on delivery, as daemon where multiple servers check one instance, as part of MailScanner where a single (replicated) database was responsible for storing all bits and pieces combined with local additional rules.
FreeBSD Dutch Documentation Project
So. It had been a while before I had proper time to look into the Dutch translation efforts again. History Due to various reasons not discussed here, I was not able to see to a proper translation. Rene did a lot of work (thank you for that Rene!). The PO system First of all, i am going to discuss a bit about the PO system, which is a gettext way of doing translations.
Kobo readers using the internet
So I have this situation, where I couldn’t get my kobo reader to connect to the internet and fetch updates and/or use kobo+ for example. I started debugging with Ubiquiti ages ago to see where the problem lies. In the meantime I was unable to continue with this, but I had an interesting thought yesterday. I sniffed the traffic from the hardware (mac) address of the ereader and noticed that it tried to resolve: www.
