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.

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.
