YDNS: How to add a custom domain

We recently added support for custom domains to YDNS. That feature allows you to have YDNS manage your DNS records for your own domains. That makes YDNS not only offering free dynamic DNS services but also DNS services in total, since we added support for a few more record types as well.

I see many people adding domains the wrong way. Our system currently does not test whether a domain exists or not; it will frequently check its nameserver records for correctness. If they are not configured correctly, YDNS will disable those domains for further use (this will also happen if you have successfully validated your domains in the first place, but changed its configuration afterwards).

To correctly add your domain to YDNS, follow these steps:

Login to your Domain registrar’s Control Panel. It shall offer a section where you can change the nameservers which are responsible for your domain. If you cannot find this, you cannot add your domain to YDNS. In case you successfully found the appropriate section, replace your domain’s name servers with these two (and of course delete the previous one if they still exist after that):

After you’ve one that, you can add your domain in YDNS by navigating to the Domains page and use the “Add Domain” link on the right side on the top of the page. You may enter your domain name appropriately (e.g. “”) there. Our system will accept invalid domain names as well, but they’re deleted automatically after two weeks if they cannot be validated during that time frame.
Once your domain configuration is synchronized through the internet, our system will automatically flag your domain as being active and you can start using it.

yDNS receives some updates

Today I spent another update to yDNS: The support for multiple records per host. Before the update happened, only one record per host was allowed due to implementation restrictions. Now you can add an arbitrary number of records to each of your hosts. I also added support for three additional record types: CNAME, MX and TXT. The update resource for API calls has been updated as well: It now supports two new parameters:

  • content (alias for ip, can hold any content value for the record, not just IP adddresses)
  • record_id (if specified, the specific host is updated directly instead of guessing which record has to be updated)

I have plans to add support for custom domains. But that’s not final yet. Everyone is invited to test the new features in yDNS and report issues/suggestions by creating an issue on the project’s Github site.

Behaviour of Yaourt has changed

I’ll do system updates at least one time in a week, most notably to get more recent version of software installed. My zbox is powered by an Arch Linux installation, which does a fantastic job. Very reliable and fast. In the past I used yaourt (inofficial frontend to Arch’s package manager pacman) to update the system by using yaourt -Syu but this only updates the packages that are inside the official repositories, not the packages that are in AUR. AUR packages were updated with this syntax some time ago as well, but now I have to use yaourt -Syua to do the job.

Daft Punk brings back the disco era

Usually I don’t write about other musicians, but I should! Especially about them who I like. Daft Punk is one of them. While I got first in touch with their sound by my brother back in the 90s, I followed their musical career in the past 13 years and they have become unquestionably one of the most awarded artists ever.

Now, eight years since their last studio album Human After All, they’re gonna release their new Album Random Access Memories on 21st May, 2013 on Columbia Records. It contains a phenomenal set of guest appeareances, such as Giorgio Morauder, Pharrell Williams, Nile Rodgers, Todd Edwards and some more. Some of these people had big influence in the disco era in the 70s. First single of that album might be “Get Lucky” featuring Pharrell Williams (Vocals) and Nile Rodgers (Guitar). The time couldn’t be better to release an album with this kind of music – in a world, where synthetic sound is everywhere, but no groove anymore. This could become the best-selling Daft Punk album ever.

Update 2013-04-24: Get Lucky was released a few days ago and got the most streamed song on Spotify of all time – within 24 hours. Btw, you can listen to it on Spotify for free.

freenode outperforms Quakenet as the largest IRC network in 2012

I already mentioned in one of my previous blog post from August this year that freenode is about to outperform Quakenet in terms of user counts. And it happened in June this year, as you can see on this graph on From all of the Top 10 IRC networks, freenode is the only one who keeps growing while all others constantly lose users. Its quite interesting when we think back to the old days when we were using Quakenet and had user counts like more than 240.000 simultaneous connections in 2005, and roughly about 75.000 in 2012.

Ubuntu’s new Unity Desktop

Ubuntu 11.04, codename Natty Narwhal, released on 28th April 2011 is the first Ubuntu Version which is powered by the new Unity desktop for the Desktop version as well. The UI is pretty awesome, there are a few similarities to the Mac OS X Desktop, e.g. the combined Application bar and Title bar of the applications. That looks great and it saves some space, especially on small screens.

However, I am experiencing frequent crashes from the X server. This is pretty uncool when you’re working on an live event and the screen gets black. It may be an bug from Unity, but it may also be an bug in the X server itself. The Ubuntu project is willing to change to the Wayland X server to replace the X.Org one, which is expected to be more lightweight.
