Almost All .CZ Domains Are Ready for The February DNS Maintenance
A global DNS maintenance is scheduled for February 1, 2019, and authoritative server operators must get ready for it. That is why we dedicate our today’s article to the state of readiness of .CZ domains for changes that will be effective from the beginning of next month.
The Czech Republic has taken the first step towards using electronic IDs abroad
Less than half a year since the launch of new electronic national ID cards, the Czech Ministry of the Interior provided their detailed description to other Member States and initiated the process leading to their mutual recognition abroad under eIDAS.
Data from routers map connection speed
One of the less known advantages of the Turris router is the possibility to verify quality of Internet connection, the so-called QoS (Quality of Service), i.e. especially to measure the download and upload speed, IPv6 support, DNSSEC and parameters connected with net neutrality. Such a measuring may serve to analyse the use of the line and to evaluate whether paying a high speed fee is unnecessary. The experience of the Turris router users shows that the majority of their time online is spent in the slowest zone (0-250 kbps). Moreover, even when the majority of data is transferred in higher speed, fast operation may have only a tiny representation from the time´s point of view. Especially those who do not spend a lot of time watching videos pay extra for high speed connection for a relatively short time of use, mainly for the moments it takes to load a page or download and send an e-mail.
Reinstalling Openldap in CZ.NIC
At the beginning of the year, a need arose to reinstall the LDAP, which had been running in CZ.NIC on an older OS, and I figured I did not want to miss such an interesting “challenge”. And I was very excited about it until I realized that the same server was, as a “bonus”, probably, running Freeradius and Radsecproxy with a connection to Eduroam. Of course, this was also to be rewritten as the syntax between the versions Freeradius v2 and v3 had changed a little bit. Only then I understood and admired the patience of people who set these things in CZ.NIC before me and I know that they have “enjoyed” this quite a lot. But this is a topic for another day, as this blog post should be about installing LDAP. I emphasize that this article discusses only basic LDAP settings.
From the life of an online wanderer
Today, I would like to go back to the topic I brought up in my earlier blog post. At that time, I was horribly angry at the administrators of photo sharing servers. I was angry at the absence of better mechanisms to check the photos people upload. Why don’t they have a person who would take a look at them? Why don’t the make the albums private by default? I could go on, but after almost two years of what seemed like fighting windmills, I have realized one thing. It’s not the administrators’ or providers’ fault — everyone is responsible for their own actions.
GeoIP in Knot DNS 2.7
The latest release of our authoritative DNS server, Knot DNS 2.7, comes with several new features. One of them is the GeoIP module for geography-based or subnet-based responses. In this article, we will briefly explain what the module is for and how it works and then we will explore how to set up and configure the module on your Knot server.
Beware of encouraging pupils to use social networks and messengers
Many a teacher is trying to find out the best tool for communicating with pupils. Nowadays when most children are given a mobile phone in lower primary, the logical choice would be social networks and various messengers, be it Facebook, WhatsApp or Viber.
How to survive scheduled DNS maintenance
DNS has been in use on the Internet for more than 30 years — now it is time for its worldwide maintenance that shall, for the first time in the existence of DNS, require coordinated actions from all operators of DNS servers and DNSSEC validators.
ID4me – single sign-on and domains the German way
On August 14, over 50 representatives of internet organizations met at the headquarters of DENIC, the German top-level domain registry, to attend the first ID4me summit. ID4me is the current name of the project, which was started last year under the name DomainID — I mentioned it briefly in my presentation at our last year’s conference IT 17.2. It was initiated by the .DE domain administrator, together with the major German registrar 1&1, and Open-Xchange, the operator of online collaboration tools. However, there are many other companies that are willing to support it, including the UK domain registry Nominet. The goals set by the project are quite familiar to us — reducing the number of passwords and registrations that people need while using the Internet. Like CZ.NIC with its mojeID project, the authors of ID4me have come to the conclusion that the domain world is just the place for an attempt to achieve these goals.
