The ErgoDox EZ reinforcement kit...

2017-05-20 - Tags: ergodox-ez tastatur keyboard

What's that?

The first persons to get the ErgoDox EZ were lucky, and happy. Only until they learned, that there is a little flaw in the first Batch of ErgoDox-EZ's (what's the correct plural for that?). The thing is, if you happen to connect your EZ to the computer without having the two halfs connected properly, the keyboard might stop working for good. Everybody from the first batch got this little Email from Erez explaining things and offering this reinforcement kit. I chose the reinforcement kit - as it needs a bit of soldering, it might not be the solution for everybody.

Just to make that clear, this does only affect a very little number of the first customers to receive the ErgoDox-EZ - only those, from batch 1 - not batch 1a or batch 2. Only if your ErgoDox got this batch number. And you got an email from Erez about this problem, too. So, if you did not receive this email, you probably have a different batch.

Why do I create this post, if it does not affect a lot of people:

  • maybe in future times, this might be interesting for others. and for me as well...
  • I want to show (off) the internals of the ErgoDox-EZ and the very good quality of it
  • and for the fun of it

This kit needs to be soldered and fixed at the PCB of both halfs of the ErgoDox, but it is actually not that hard...

What's in this kit?

Today I received the Reinforcement Kit from USA. It took quite some time to get shipped and through customs. Which is a bit strange, as the kit only contains

  • two very little PCB
  • two new backplate stickers for your ergodox halfs
  • a 3 page instruction manual with photos

And that's it! The two little PCBs need to be soldered to the PCB of each keyboard half, should not be so hard....

Installing the kit.

It took me about 30 minutes in total to do that, and I'm really not practiced in soldering such delicate things. It worked fine, as it seems.

First you need to remove the stickers from the back, as below the sticker there is one screw that needs to be removed. You only need to loosen those screws and then take the lid off...

To remove the stickers, a cutter actually comes in very handy.

Just to mention: on the big sticker there is actually a little small sticker with your serial number. I removed that first (also with the help of the cutter) and kept that for reattaching to the new stickers afterwards...

After that, remove those screws one after the other. That should be more or less self explanatory😉

I kept the screws "lying" in the holes, so I did not need to search for them when putting everything back together. So I removed the lid with the screws still inside the holes, but lose.

You might have noticed that I put some valcro tape on the back of both halfs. This way I can "stick" them together for transportation purpose. In my case it’s a bit tilted, so I don't need to remove the tent. Makes transporting the ErgoDox EZ a bit more safe and easy.

So, back to the Reinforcment Kit. When you removed it lid, you reveal the real beauty of your keyboard, the inner soul ;-)

"Above" (or below, depends on your point of view) the inter-keyboard-half-connector (or simple: audio jack), there you need to solder the little PCB that came with the kit to the PCB of the keyboard:

If you have a look at the labels on the keyboards PCBs, they're actually wrong... meaning that the left half of the keyboard is actually labeled right. But this is probably due to the production process. So keep calm, all is ok..

So, now you only need to fix the kit-PCB to the big one. This not that hard to do, you only need to solder it on 4 places. What makes it a bit hard is that it is so damn small! If you're not used to soldering such delicate things, take your time. For some experienced guy this is probably done within a couple of minutes.... I took my time doing that... and it ended up being really kind of ugly:

it really does not look good, but it seems it is working fine. At least the keyboard is... and that's what counts for the moment ;-)

After soldering you only need to repeat the steps above in the opposite order... and voilá! You reinforced your Ergodox-EZ!

I asked Erez how would I know, if the soldering went on well? How do I know that the fix is in place properly.... the answer was "if your keyboard is still working, everything is fine." - So, as I type this on my reinforced ErgoDox-EZ, it seems to be all fine!

Drones and such...

2017-05-19 - Tags: drone legal gesetzliches drohne

Some of you might know, that in Germany there is a new regulation for drones and UAVs (unmanned areal vehicle). I just wanted to post something about that. As this is my Hobby and I'm directly affected by this...

I already wrote some things about that here.

Now, since a couple of months this new regulation is effective, wich is aiming a lot at those camera carrying drones like Phantom and such. (This list is not intended to be exhaustive. This is what I researched for me and my type of flying)

  • you are not allowed to fly higher than 100m - but you might get a permit (new)
  • you need to stay in line of sight
  • you are not allowed to fly above crowds of people
  • not allowed to fly near highways (Bundesstrasse, Autobahnen) and water ways (most bigger rivers)
  • not near official buildings like police and such. Also not near or above factories (Nuclear Plants)
  • not above private property, unless you have a permit from the owner. (or your drone does not carry a camera or video transmitting device or is lighter than 250g)
  • all drones that are heavier than 250g need a non flammable plate with the full address of the owner
  • if your drone is heavier than 2kg, you need a proof of knowledge (some kind of test, I guess)
  • everything heavier than 5kg can only be flown if you have a dedicated permit for that thing
  • flying at night is forbidden
  • drones heavier than 250g can be flown FPV only if you have a spotter nearby, who will warn you if anything happens. Before the new regulation, the spotter actually needed to be ably to fly the drone...
  • is your drone lighter than 250g, you can fly without spotter, and you do not need a plate on it
  • in all cases, you need to have an insurance
  • it seems like, it is not necessary to have a special permit if you want to fly for business (or it is easier to get one)

in addition to that, the old No-Fly-Zones (Airports, Helipads etc) are also still valid. Also flying in natural reserves usually is vorbidden.

For the usual drone-Flyer thit actually does not mean a lot of change. Well, except for those, who like to fly 200m high, this might be a bit annoying.

But the most important thing, it seems nobody actually knows, that these regulations existed and do exist! Especially the media is not really a role model here. It seems like every 2nd shot needs to be a cool drone shot, no matter if flown over cities, private property, autobahns or whatever.

Just the other day on RTL, they filmed in the garden of some Messie using a drone! I bet they did not have a permit for doing that. Not only that flying above private property is forbidden, also it is not allowed to invade someones privacy with or without a drone - and this was privacy invasion, if you asked me.

No wonder people get afraid of this technology. "Can you film me from up there" and if I show them, what kind of photo that is, they are usually reassured.

But if dad goes in to the next tech marked and buys a drone for his son, the guy at the counter will not tell him, that he needs to have an insureance and for that heavy thing you need to have a proof of knowledge and btw. flying before the age of 14 is not allowed"... No, he will not say something like that, because that might prevent the deal.

realy a sad world

New blogging software

2017-05-16 - Tags: java jblog security

I did complain about wordpress several times (for example here). I took that for an opportunity, to take on my software development skills and use a weekend or two to build a new blogging software. Well, th result is this wonderful (well... hop so) page here.

PHP sucks

To stop all PHP fainbois from whyning, I do not like PHP very much, because I don't know it very much. Hence, wordpress is also kind of a mystery for me. The configuration works with luck, let alone get php to do what you want in a more secure way.

so, my blog was hacked several times during the last year now and this is pissing me off! So, I wanted to use a java based solution, but it seems like there is no simple, easy to use one out there.

so why not do it yourself?

exactly. That was my thought also. Could not be so complicated, could it? So, I wanted to create a blogging software that

  • has a simple technology stack
  • does not need a complex plugin funktionality. If it cannot do, what I like it to do, i rewrite it
  • themes or designs... well... er... could be better, but I think this is ok
  • Security, that is the point. I created the blogging software (called it jblog - not rally creative) myself and it is not so complex as wordpress. So we should be ok. I guess. But I know for sure, that th standard wordpress exploits wont work no more!
  • Intrnationalization... also a topic. jblog does only do 2 languages, German and English (I do not speak more, so I don't need more for my blogs).
  • whitelabeling. I have a couple of domains, I wanted to reuse / revive with this project.
  • one administration: I did not want to create the same thing 3 times, I wanted to have the same thing look like 3 different hings. Hence there should only be one administration page.


I am quite ok with what I accomplished here. Although it took longer than one weekend, it was finished quite fast. I lik that.

But please: if some links do not work anymore, some images look strange or are missing - I will fix this eventually emoji people:smirk

the different blogs - this blog here

the private main blog. Will cover topics like hobby, drones, games, gadgets etc. - the java blog

There I will put all my opnsource stuff, like morphium. And all the other programming tips and tricks I wrote over time. Hmm... seems like 'java blog' is not the right term...

This should be a business site anyways. So, here I will put in topics about my professional carreer, Scrum, processes etc.


well, this is going to be tough. I cannot produce content for 3 full blogs. Even filling one is quite hard. But I will try. And we will see, how that works

technical discussion

as mentioned above - not here, but at emoji people:smirk

Sometimes, I hate Wordpress

2017-04-04 - Tags: php blog

This site was hacked again!

Well, the title is a bit missleading, as it is not only Wordpress at stake here, it is also related to php and obviously apache also.

I was not very active here for a couple of weeks, and obviously missed an update for Wordpress and some of the plugins. And that was enough for a white hat hacker to hack the site... well white is probably not the right color, as he posted links to illegal sites here.

Disclaimer: It was not me adding those links to download portals of illegal stuff! unfortunately I cannot tell, where the attack came from.

But I can tell, that he only had access to the Wordpress-Stuff. This happened again! << Sarcasm_mode >> Apache, PHP and Wordpress are in this respect really a _great_ team... << / Sarcasm_mode >>

I know, that this will cause some people to call me a troll, but I can tell you, from a professional point of view, there are way better solutions from a security point of view to create websites. Yes, most of them are complicated and complex. But at least, you cannot get hacked that easily...

PHP is a fine language, if you want to build a calculator or something like that. For professionals this is crap. Even Facebook needed to create their own interpreter (yeah, because of speed issues, but who knows what else).

Sorry, this php stuff pisses me off... was hacked here, that happened to customers of mine using PHP-based software....

Need to find something more reliable...

Test Of Tools: Nach Hause Telefonieren - VPN mit OSX / iPhone

2016-05-30 - Tags: vpn howto test of tools osx security

no english version available yet

Eigentlich kein echtes "test of tools", weil nicht viele Tools vorkommen, aber dennoch hab ich es mal zu dieser Rubrik gepackt.

Folgendes Scenario: man ist unterwegs oder in der Arbeit oder sonst wo und möchte kurz daheim mal auf seinen Servern eine Datei holen oder mal schnell eine TV-Aufnahme mit der Dreambox Programmieren. Eine eigentlich lösbare Aufgabe sollte man meinen. Hier eine Aufstellung der von mir getesteten Möglichkeiten (und ein paar Tipps dazu):

"Eigenes" VPN mit SSH

Naja, so richtig als VPN kann man das nicht bezeichnen. Aber man kann per SSH ne Menge machen. Das einzige, was man tun muss, ist in seinem Router einen Port frei schalten. Bei der Fritz!Box ist das unter Internet->Freigaben:

Man kann Portfreigaben deaktivieren, aus Sicherheitsgründen hab ich hier mal ein paar versteckt. Der Dynamic DNS Eintrag ist wichtig (s.u.) und mit dem Button "Neue Portfreigabe" kann man eine Neue Freigabe einrichten - das sieht dann so aus:

Dabei gibt man an, welche externe also öffentliche port-Range (von-bis) auf den Computer im eigenen Netz geleitet werden sollen. Für SSH sollte der Zielport 22 sein (das ist der Standardport für ssh), Protokoll ist TCP. Leider gibt es in der Vorauswahl von Anwendungen SSH nicht, weshalb man auf "Andere Anwendung" gehen muss. Achtung: Nutzt nicht Exposed host! Dann wird der gesamte Traffic an den Rechner weitergeleitet und das will man normalerweise nicht.

Das ganze kann natürlich nur funktionieren, wenn man auch dyndns oder so was eingerichtet hat - sonst "findet" man seinen Router ja gar nicht und kommt somit auch nicht an die freigegebenen Ports.

Wobei man da schon beim nächsten Problem ist: Wohin sollte man den Port weiter leiten. Man benötigt da also irgendwas, was nen SSH-Server laufen lässt. Man kann das schon auf der FritzBox selbst machen, oder normalerweise auch auf den meisten anderen Routern, aber das erfordert doch ein wenig Geschick: Anleitung dafür gibt’s zum Beispiel hier.

Wenn man in der Firmware des Routers nicht rumfummeln will, dann benötigt man irgend einen anderen Rechner im Netz, der als SSH-Endpunkt dient. Da funktioniert z.B. auch die Qnap (wobei man evtl. den SSHD hier auch korrigieren muss: siehe hier). Ein Mac oder Linux Rechner wäre Ideal, ein Windows-PC geht auch - allerdings muss man sich dann nen SSHD installieren (mit cygwin z.B.).

Der Standard-Port des SSH ist Port 22. Man sollte allerdings vermeiden, den Port 22 nach außen frei zu schalten, sondern man sollte da irgend einen anderen nehmen, am besten was über 1024 oder sogar noch größer. Da alle ports < 1024 gerne mal gescannt werden und es ne Menge Scripts gibt, die versuchen mit "default"-Passwörtern einzubrechen (und sich ein paar MöchtegernHacker dann tierisch freuen, wenn sie "eigebrochen" sind... dann sind die total 1337).

Da sind wir dann auch schon beim nächsten Tipp: gute Passwörter verwenden! Oder, wenn man den Zugriff nur von wenigen Rechnern aus machen möchte, dann kann man auch eine Public-Key Authentifizierung verwenden und die Password-Auth Komplett ausschalten. Die Konfiguration dafür ist ein wenig abhängig vom Betriebssystem aber im Allgemeinen muss man im Home-Verzeichnis des Users, der sich anmelden soll (auf dem SSH-Server!), ein Verzeichnis namens .ssh anlegen. Dieses sollte nur für den Nutzer les- und schreibbar sein. In dem Verzeichnis legt man ein File an, names "authorized_keys". Das ist ein einfaches Textfile in dem man die PublicKeys aufnimmt.

Die Public-Keys muss man dann auf dem Client erstellen, also auf dem Notebook mit dem man unterwegs ist. Das funktioniert auch wieder recht unterschiedlich, unter Windows nutzen viele Putty, da gibt’s dafür nen Menüpunkt. In der Shell tippt man einfach ein

ssh-keygen -t rsa -b 2048
Damit wird ein neues Keypair erzeugt. Das liegt wieder in dem .ssh-Verzeichnis des Users und besteht aus 2 Dateien: id_rsa und Die pub-Datei ist der Public key, dessen Inhalt müsst ihr einfach in das Authorized-Keys File auf dem Server einfügen. Dann sollte der Zugriff gehen.

Und wie geht das jetzt mit dem Tunnel? Dazu muss man im Client den Aufruf entsprechen Konfigurieren. Bei Putty unter Windows gibt es da Dialoge für die Einstellung der tunnel. Aber auch in der Kommandozeile geht das recht simpel:

ssh -l user -L1234:
so wird z.B. eine Verbindung zu aufgebaut. Wenn man sich erfolgreich mit dem Benutzer "user" eingeloggt hat, wird ein Tunnel geöffnet: Alle Anfragen an den lokalen Port 1234 werden über SSH weitergeleitet an den Server, welcher seinerseits die Anfragen und Daten weiterleitet an in diesem Fall den Server mit der IP, Port 80.

D.h. wenn ich jetzt in meinen Browser die URL http://localhost:12345/ eingebe, lande ich auf dem Webserver mit der IP

Man kann zwar nahezu beliebig viele solche Tunnelangaben beim Aufruf von SSH machen, das ist aber wenig spassig, und man ist auch immer auf der Suche nach den richtigen Ports. Zum Glück gibt es auch dynamische Ports

ssh -l user -D 1234
Damit wird ein dynamischer SOCKS-Proxy erzeugt. Dieser funktioniert quasi identisch zu dem manuellen Tunnel mit -L, aber er baut dynamische Tunnel zu beliebigen Zielen auf. Nachteil: die Anwendungen, die man nutzen will, müssen SOCKS unterstützten. Die gängigen Browser tun das alle, aber bei anderer Software wird es schnell eng...

Außerdem kommt man so auch nur schwer an die Freigaben von z.B. seinem NAS ran oder so.

Übrigens: das funktioniert auch mit dem iPhone - die SSH-Clients für das iPhone unterstützen alle auch Tunnel...

die Flexibilität ist natürlich extrem, ich kann jeden beliebigen Port weiterleiten. Allerdings muss ich das auch, wenn ich darauf zugreifen will.

Die Nachteile liegen somit ziemlich auf der Hand: man muss alle ports mehr oder minder manuell mappen und dann funktioniert es auch nicht immer reibungslos (AFP-Sharing z.B.). Namensauflösung darüber zu machen ist auch schwer, da man kein UDP-tunnel machen kann, sondern nur TCP. Deswegen ist das eine recht gute Lösung für den Notfall, aber für den mehr oder minder täglichen Zugriff ist das nix.

TestOfTools Rating: 4/10 Punkten


Pseudo VPN mit ShareTool

Im Endeffekt ist das eine grafische Oberfläche für die oben beschriebenen SSH-Methoden + noch mehr. Allerdings ist die Software nicht umsonst - dafür wirklich "Narrensicher";-)

Sharetool 2 bekommt ihr hier - probiert mal die Demo aus, das ist echt ok - die $20 sind gut investiert, wenn man auf "daheim" zugreifen möchte.

Sharetool benötigt allerdings einen Mac auf dem es laufen kann - Linux oder Windows läuft leider nicht. Was sicher einer der Nachteile von Sharetool ist. Allerdings ist die Einrichtung denkbar simpel und man benötigt nicht mal so was wie Dyndns - das erledigt der Sharetool Service. Auf dem Server, also dem Rechner im Heimnetz, startet man Sharetool und konfiguriert das sharing:

Dabei könnte man seine eigene Portfreigabe verwenden, oder sich von sharetool einen eigenen Port konfigurieren lassen - sofern euer Router UPNP versteht. Falls ihr das das erste Mal macht, müsst ihr noch einen Login anlegen. Der Server meldet sich dann unter dieser Kennung mit seiner öffentlichen IP-Adresse an. Clientseitig läuft das genaue "Gegenteil" - man loggt sich ein, erhält die IP Adressen der verschiedenen Netzwerke unter eurer Kennung und man kann sich aussuchen, wo man sich einloggen will:

Nach dem Login kann man aus den bekannten Netzen wählen und sich ggf. verbinden. Dafür ist zwingend ein User auf der anderen Seite nötig, als der ihr euch einloggen könnt. Ich würde aus Sicherheitsgründen dazu raten, einen eigenen User nur für diesen Zweck einzurichten, der sonst keine Rechte am System hat - Das kann man am Mac ja relativ simpel machen. Vergebt für diesen User aber bitte ein vernünftiges Passwort oder authentifiziert euch mit dem Public-Key des SSH (s.o.).

Auf dem Mac kann man das auch in /etc/sshd_config einstellen, genauso, wie unter Unix üblich. In der Systemsteuerung gibt’s das Häckchen "Entfernte Anmeldung". Das startet, bzw. stopped den SSHD. Wenn ihr also eine Änderung an der /etc/sshd_config gemacht habt, solltet ihr den Server kurzt neu starten. Hier die wichtigsten settings:

PubkeyAuthentication yes - ist per Default an, kann man aber explizit im File setzen, wenn man möchte AllowRootLogin no - sollte zwingend aus sein PasswordAuthentication no - aus, falls man sich nur per PublicKey authentifizieren möchte, ansonsten müssen ALLE user ein gutes Passwort haben ValidUsers USER1 - so kann man den Login auf nur einen User reduzieren, alle anderen dürfen nicht
Mit diesen Settings ist auch euer Mac einigermassen sicher für angriffe von außen - allerdings würde ich immer ein gutes Passwort vergeben.

Hat man es geschafft, sich anzumelden, bekommt man von ShareTool eine sehr praktische Auswahl aller Bonjour-Services:


Durch einen Doppelklick kann man sich dann mit dem entsprechenden Service verbinden - so als wäre man im eigenen Netz... Und möchte man dann noch "Anonym", also über seine eigene Home-Verbindung im Internet surfen (das ist manchmal ganz praktisch für sehr strikte firmenpolitik), dann kann man unter Options den Menüpunkt "Browse Web securely" wählen. Das öffnet den Firefox und surft dann über den SSH-Tunnel und seine eigene Leitung.

Nachteile von dieser Lösung: Man bekommt eigentlich nur relativ Problemlosen Zugriff auf Bonjour Services, alles was darüber raus geht, erreicht man nicht. Man kann zwar auch eigene Services registrieren, aber das ist ein gefummel und habe ich noch nicht hin bekommen - wenn Ihr da ne Idee habt, immer her damit ;-)

Aber für die Meisten sollte das gut reichen, da der Zugriff auf Shares, Web, Printer und Screen Sharing gut funktioniert.

Ist noch erschwinglich und ist eine solide 90% Lösung, sofern man einen MacServer hat - und das können nicht viele von sich behaupten.

TestOfTools Rating: 7/10 Punkten


Das ist eine "echte" VPN Lösung, die den Netzwerktraffic auf einer der unteren OSI-Layern verschlüsselt. Das ganze funktioniert auch über SSL und verlangt keine besonderen Einstellungen oder Fähigkeiten vom Router oder Provider  - es gibt auch eine Implementierung für das iPhone oder Android, allerdings nicht nativ, muss gesondert installiert werden.

OpenVpn wird immer beliebter, hat aber leider noch nicht in viele Router einzug gehalten. Deswegen benötigt man auch hier einen eigenen Server, der als OpenVPN-Server fungiert. Hierfür muss im Router eine Portfreigabe eingerichtet werden - normalerweise UDP 1194. Ist aber frei wählbar.

Für den Zugriff vom Mac aus benötigt man einen Client, da auch hier keine native VPN-Implementierung verfügbar ist. Am besten bewährt hat sich bei mir das Tool Tunnelblick, obwohl es noch immer im Beta Stadium ist. Dennoch klappt das recht gut, auch wenn der einwahlvorgang immer recht lange dauert (im Vergleich zu den anderen hier vorgestellten lösungen).

Als OpenVPN-Server habe ich die Qnap gewählt, da geht das recht simpel:

hier kann man eigentlich nur den Haken bei "Server aktivieren" anschalten, dann läuft alles. Man muss nur noch die Konfigurationsdatei herunterladen und alles sollte einigemassen passen. Allerdings muss man da drin die Öffentliche IP Adresse vermutlich ändern. Da steht, wenn man nicht DynDns auch über die Qnap macht, die gerade aktuelle öffentliche IP drin. Das funktioniert dann für den Moment, aber morgen nicht mehr.

In Tunnelblick muss man nur ne neue Config anlegen, das erklärt sich mehr oder minder von selbst... auch wenn es einige Schritte sind.

Leider kann man hier das routing nicht einstellen, d.h. man surft immer komplett über die Leitung "daheim". Also ein Zugriff nur auf das Netz, ohne den ganzen Traffic darüber zu leiten ging nicht. Auch gibt es wohl einen Bug in der Qnap: Wenn man die Default-Route ausschaltet, geht gar nix mehr. War zumindest bei mir so...

Das ist allerdings auch erstaundlich simpel einzurichten und es funktioiniert recht solide, wenn man einen Brauchbaren Server hat. Dennoch gibt’s ein paar Punktabzüge, da die Konfiguration so etwas nervig ist. Im normalfall würde ich da 10/10 Punkten vergeben, aber da das ganze leider auf der Qnap ein wenig krankt bekommt das ganze weniger. auch ist schade, dass es keine Nativen Clients von Apple für OSX und/oder iOS gibt, so wie für IPSec Und leider auch keine Implementierung für die Fritz!Box.

TestOfTools rating: 8/10


IPSec VPN mit Fritz!Box OS6.0

Das ist eigentlich wäre das die optimale lösung. Allerdings war es bisher immer ein Graus, IPSec selbst zu konfigurieren. Vor allem, weil die Router spezielle Protokolle korrekt weitergeben mussten. Der Support für IPSec war da nicht so verbreitet. Obwohl es angeblich die sicherste VPN-Variante sein sollte.

Zum glück ist die konfiguration mittlerweile in der Fritz!Box so stark vereinfacht worden, dass man das in ein paar Mausklicks zusammengestellt hat. wichtig: Man muss für jeden VPN-Zugang einen User anlegen. Das Passwort dafür sollte entsprechend komplex sein.Die VPN-Einstellungen sind auch unter "Freigaben" zu finden, dort gibt es einen Reiter "VPN":

Dort kann man dann einen User für den Remote Zugriff einrichten, oder netz-zu-netz verbindunge (also Fritz-zu-Fritz) einrichten.  Das ist ganz sinnvoll, wenn man zwei Standorte verknüpfen will - die fungieren dann netzwerktechnisch als einer - was den Zugriff auf Fileserver etc. natürlich stark vereinfacht.

für uns hier wichtig, ist der erste Punkt: Fernzugang für einen Benutzer einrichten. Dort ist eigentich nur das Häckchen für VPN zu setzen, ein gutes Passwort zu vergeben und das war es schon. Bei Bedarf kann man dem User auch noch Zugriff auf andere Services der Fritzbox gewähren. Das ist ganz interessant: wenn man aus dem lokalen Netzwerk auf die Fritz!Box zugreifen möchte, muss man ein Passwort eingeben. Macht man das selbe über das VPN, dann kommt ein User/Passwort login - aus Sicherheitsgründen!

Die emailadresse kann übrigens auch als Login benutzt werden, wenn ich das richtig verstanden habe. Bisher hatte ich das aber noch nicht nutzen müssen. Am Ende der ganzen Prozedur, kann man sich noch die Einstellungen für iOS und Android anzeigen lassen:

Mit diesen Einstellungen kann man auch recht simpel den Zugriff von OSX aus einrichten. Dazu muss man eine Neue Netzwerkverbindung einrichten. Unter Systemeinstellungen->Netzwerk kann man durck klicken auf das "+" eine Neue Verbindung einrichten.

Nach dem man auf den + geklickt hat, muss man nur noch Cisco-VPN auswählen und die Einstellungen von der Fritz!Box eintragen. DAbei auch nicht die "Authentifzierungseinstellungen" vergessen, denn dahinter verbirgt sich die Gruppe und das Shared Secret. Und auch wichtig: Unter "Weitere Optionen" muss der für das Zielnetz gültige DNS angegeben werden - also die IP-Adresse der Fritz!Box - sowas wie oder so.

Das alles funktioniert normalerweise recht gut - auch hier ist wieder eine Dyndns-Anmeldung nötig. Allerdings hat das ganze einen kleinen Haken - man kann nicht mehr einstellen (OSX 10.9 mavericks), dass nicht der gesamte Traffic über die Leitung gehen soll. Das konnte man früher mal einstellen, ist aber jetzt weg.

D.h. wenn ich eingewählt bin, geht der gesamte IP-Traffik über das VPN.

Korrigieren kann man das allerdings recht einfach: Es gibt eine Route, über die das geregelt wird. in der Shell kann man das recht einfach korrigieren. Allerdings ist da manuelles Eingreifen nötig. Für die meisten ist das vermutlich eh kein Problem, sondern eher ein vorteil.

Der einzige Nachteil dieser Lösung ist, dass man wenig einstellen kann. Aber sonst ist das doch eine der besseren Varianten. Leider funktioniert es aber nicht über 3G oder LTE - zumindest bei meinem Anbieter wird IPSec nicht unterstützt. Evtl. ist das bei anderen Anbietern anders, im Zweifel solltet ihr euch erkundigen. Im WLAN/LAN sollte es eigentlich funktionieren, aber auch hier ist man Abhängig vom WLAN/LAN Route. Wenn der IPSEc auch nicht unterstütz ist man .... angeschmiert. Deswegen auch hier nicht volle Punktzahl:

TestOfToolsRanking: 9/10


Irgendwie gibt es wohl keine 100%-Lösung, an der man nicht lange rumbasteln muss. 100% - zumindest was die Flexibilität und routing etc betrifft, könnte man vermutlich nur mit einem eigenen Linux-Server und viel Zeit erreichen. Wenn man sich da reinfuchsen will, ist das sicherlich die 100% Lösung.

für die allermeisten Zwecke sind die  hier vorgestellten Wege (abgesehen vom ersten vielleicht) völlig ausreichend. Wer spezielle Anforderungen hat, muss sich auch speziell darum kümmern.

Mein Favorit momentan ist das IPSec-VPN, da ich dafür nicht noch einen eigenen SSH oder OpenVPN-Server benötige. Ich konnte aber auch eine ganze Zeit lang ohne IPSec leben und das ganze mit ShareTool bzw. Openvpn erledigen, da ich hier (noch) einen MacMini rumstehen habe, der gerne auch mal was tun soll ;-)

Entscheiden müsst ihr wohl von Fall zu Fall, welche Lösung am besten auf eure Bedürfnisse passt, da alle Lösungen eigene Nachteile haben:

  • SSH manuell ist viel zu kompliziert und erfordert eine Menge Wissen über die Dienste, die man ansprechen will. Für Notfälle aber sicherlich sinnvoll
  • Sharetool zeigt nur Bonjour-Services, der zugriff auf andere ist schwierig
  • Sharetool kostet Geld
  • OpenVPN und ShareTool benötigen beide einen Server auf dem sie laufen können
  • IpSec natürlich auch, aber die Fritzbox unterstützt es mittlerweile
  • OpenVpn hat keine Native Implementierung in OSX oder der Fritzbox.
  • OpenVPN ist beim Verbindungsaufbau recht langsam

Mechanical Keyboard – the Razer Blackwidow Chroma

I type a lot… at work, at home, on weekends and during the week. So I am a fan of good and high quality keyboards. I was experimenting a lot during the last decades (yes, that long ;-)) with several different keyboard types. Some of them were quite cool, but not really useful (like the „Fingerworks Touchstream LP“) or just quite ergonomic (like the Kinesis Freestyle or several of Microsofts Keyboards or the very old but good Siemens Ergonomic Keyboard). All of those were good in it’s way, but the best keyboards I ever had, were the mechanical ones. The good old IBM Keyboard Model M (at least I think it was called that way) – Clicky with Cherry switches and heavy like made of lead – but very cool to type on and everlasting.

After that, I was using a lot of „normal“ keyboards, they are quite simple, easy to use. But not as long lasting as the mechanical keyboards.

I was using the Apple-Keyboard (USB, including a number pad) for quite some time now, but I was missing some things there – and it started feeling a bit „fuzzy“ – worn out is probably the best term here. The keyboard is quite good, especially for its thickness (or should I say thinness). But it does not have the feel of the good old mechanical keyboards, we all loved…

So, I was thinking about buying a good mechanical keyboard for some time now. But if I spend money on that topic, I wanted it to be matching my needs quite good. What I was looking for, is actually not so hard to imagine:

  • as I’m a developer, I write a lot of code and text. So the keyboard should give a good typing experience
  • as I also like to play a game once in a while, I wanted to have some features like Anti-Ghosting, N-Key rollover etc.
  • as I also play and work a lot in the dark, I wanted the keyboard to be lit – preferably in a color of my choice.
  • as I do all that on a mac, the keyboard needs to at least be kind of mac OSX compatible
  • although I’m mostly not looking at the keyboard at all when typing (which makes the backlight a bit obsolete, but when playing a game in the dark, you sometimes need to find the right key to press by looking at the keyboard), I wanted it to be German layout. I was using an US-Layout keyboard for quite some time, that was working alright most of the time. But there were too many occasions, where I had to think about where the key is located, that I just wanted to press. This was annoying me a lot! A keyboard without any key labels printed on would be easier to use (like the DAS Keyboard ultimate).
  • in most cases, a fully programmable keyboard is a good choice, there you can redefine your keys to your liking. Especially if you have a windows layout on your keyboard, you’d might want to switch some keys.

Actually – there is no such keyboard having all those features! You can have a combination of two of those features, if at all. So, for some time, I was just stuck with my old Apple keyboard that came with my iMac…

Mechanical Keyboards

Why a mechanical Keyboard? And what is the difference?

First, the difference is the feeling when typing. If you ever tried a mechanical keyboard, you do not want to go back. If you work a lot on a computer, try a mechanical keyboard, just once. You will feel the difference immediately. But at first this might not only feel different, but odd. You need to get used to it. And actually you will have to learn typing on it to improve your typing a lot.

Technically speaking the difference is, that mechanical keyboards do have a dedicated switch for every key. Whereas the normal keyboards do have some kind of rubber bumper beneath every key (called rubber dome), you have to press down to close a circuit. This causes you to not feel when the key is sending its event (when it was activated), but to feel, when the key hits the bottom. Usually somewhere above that the key really fires. You don’t get proper feedback about, when a key was really pressed or not. This is something mechanical keyboards are way better in – well, at least those with the tactile switches (like Cherry MX-Blue or MX-Brown, see below).

There are different switch types, you might need to think about. Almost all keyboards are either using Cherry produced keys or at least compare their own keys with the ones from Cherry. There are more or less 3 major versions (there are a lot more, but as I see it, those are the most common ones):

  • Cherry MX-Blue: clicky switches, good feel when typed. Also a good audible feedback (you hear and feel the „click“)
  • Cherry MX-Brown: not that loud, and the click is weaker.
  • Cherry MX-Black: no click to be felt, but hard to press (special Version would be the MX-Red, which is the same as the MX-Black, but with a lower activation force)

There are mechanical keyboards en masse that work fine on a mac (DAS Keyboard ultimate for example – no printing on the keys makes it a perfect thing for typists). Most of them are considered to be „Gaming“ Keyboards why not check here. I’m not sure why, but I actually like to think those keyboards are perfect tools for professional workers on computers, too. I’m a fan of the clicky noise actually. You feel and hear the feedback from the key: „I was pressed now„. This actually makes it easier to detect typos during typing actually. Because you know, when you accidentally typed some key, or not.

The noise?

Well, this is something everybody needs to decide for him-/herself. In my experience, the „click“ on the MX-Blue switches is actually not that loud. What causes the noise is the keycap hitting the frame. This is way louder on all mechanical keyboards I tested than the actual click. Yes, the idea is, that you learn to type without hitting the bottom and creating this noise. But this is unfortunately not only very hard, but somewhat impossible. Well, when you are concentrating on it, it really works some time. But when you are writing in a rush, this definitely will make you „bottom out“ the keys which causes a lot of noise.

If you use a mechanical keyboard, you should try to get „Dampeners“ for Cherry MX-Switches. They are not really expensive (125 pieces about 10€) and usually easy to install. But it dampens the noise of „bottom out“ a lot! The people around you probably will like it way better.

Why a mechanical keyboard

There are several reasons for mechanical keyboards. Most of them are highly dependent on your own taste and way you type and work. But there are some advantages, that „normal“ rubber dome keyboards cannot provide:

  1. the Feel. Of course, highly subjective. But everybody who is typing a lot, actually likes the feel of the mechanical switches (at least, everybody I talked to about this topic). In my experience it also increases your typing speed and reduces typos – at least in my case it does (and some other people, I talked to confirmed my assumption)
  2. the durability. Where a normal rubberdome keyboard can take about 1-5 Million hits per key, the mechanical switches usually last between 20 and 60 million types (depending on manufacturer). This does not mean, that after 5 million types of the letter „A“ on a normal rubber dome keyboard will stop working. It just means, that it will feel „worn out“ – and will feel different than the key next to it, which maybe were hit a couple of thousand times less. And there will be some keys, hit more often than others (if you play games, probably WASD will be hit way more often then others)
  3. (Not only) gamer options like N-Key Rollover and Anti-Ghosting. Although this is happening mostly when playing games, it can also happen when you’re a fast typer using your 10 fingers to type. N-Key-Rollover means, that it is possible to hit N keys simultaneously (where N is a number from 1 to 105 – some keyboards state they support real NKRO, which just means, there is no limit – which limits it to 105 – maximum number of keys on the board) and the computer will recognize every single keystroke. Sometimes there is a limit to that, so usually you wont get N-Key-Rollover higher than about 10. But actually, I only have 10 fingers, this should be enough 😉 Ghosting is the effect, that when you hit several keys simultaneously, either an additional key is being „pressed“ or one of the keys you press just won’t work. This is related especially to the way the normal keyboards are built.
  4. customizability. For most of the mechanical keyboards, it is possible to get custom or just different keycaps. As most of them use the Cherry MX switches (or something compatible), you can just pull of a keycap and replace it by some other keycap of your choice. Different color, different printing, different material, different… whatever. This is actually very important for Mac users, as very often only windows layout keyboards are available. But with a couple of custom keycaps (or a whole set) you can easily change that

You need to decide for yourself, is that something you need or want to have. Especially as all this comes with a pricetag. There is also personal taste. Some people just don’t like the „clicky“ sound. Some people just love it. Some don’t need or like backlight, some love it.

If you consider buying a mechanical keyboard, just get your hands on one to play with it a bit. Maybe you can get one from a friend for some time. Be sure, you want to invest that money and that you have the right switchtype.

The right one?

As already mentioned, there is not a lot of options I could chose from…

If I only wanted a mechanical keyboard for the mac, this would be a solvable problem. There are plenty options to choose from. But as soon as Backlight comes into play, things get a lot harder. I did an extensive internet research and found many good options when it comes to mechanical keyboards only. If you have a list of features as I had, this is a bit harder. You actually find some keyboards, that are backlit, have good switches, and so on – but need software wich is not mac compatible. Darn… like the corsair keyboards – those actually looked also quite good.

One very interesting fact: all of those keyboards are labeled „gamer keyboards“. And are only available in windows layout. This is very astonishing, as the typing experience is – especially with the MX-Blue switches – very good! And I don’t really think these features are only valid for gamers. I actually like to have some makro keys on my keyboard.

This really sux… Mac Users are gamers! And there is obviously a lot of them, most game developers seem to know that as most of the games now are available for Mac and windows, very often at the same time. But hardware and „gadget“ manufacturers actually tend to ignore that fact.

Guys listen to this: There is money to make!!!!

So, when you do the internet search that I did, there actually are not many options left as stated several times above.

To be honest, the only options which kind of does match all the criteria mentioned above is the „Razer Blackwidow Chroma“ (the Ultimate would be ok, too. But the backlight color is only green and it was not so much cheaper than the chroma) and some keyboards that were only lit in blue or red and did not need any driver (like the Code2 Keyboard). But when I compare the prices of those with the blackwidow, I took the blackwidow – it was actually cheaper then some others (even without backlighting) or at least at the same price level.

I am aware that the Blackwidow actually has a windows layout printed on the keys. That is a drawback, but it has all other features.

  • I’m typing with the Blackwidow just now, and it feels great. The Razer-Green switches seem to be comparable to the Cherry MX Blue ones (loud clicky). It feels really cool, the typing experience is great.
  • Anti-Ghosting and N-Key rollover is of course a feature of the BlackWidow
  • The keyboard has backlight – you can choose from 16,8 mio colors – actually for each key individually (or change it, when typing it or change it, depending on the running application… very very cool feature! I have different profiles for Safari, XCode, IntelliJ etc. Profiles contain different Macros and keybindings. Very cool feature!)
  • Here it comes: although not really stated on the Website of Razer (, it works with OSX! There is a driver software available for current MacOSX which gives Mac Users the opportunity to use all of the cool features of the Blackwidow chroma. I actually just don’t understand, why this is not stated explicitly on the website?!?!? actually, there is a statement somewhere there that you „cannot use the windows version with the mac driver“. Well – there is no „Windows“ or „Mac“ Version there… really strange.
  • The chroma is available in German Layout, all keys are there. But unfortunately only windows style. This is sub optimal, but ok. I can live with it, as long as all other keys work right.

The driver software called „Synapse 2.0“ is nice, but the registration has to be done online. You need to register there in order to have your keyboard working properly…. This is… not really good. For those of you, who are capable of doing: install a firewall rule after registration, then everything still works locally but no data is being transferred.

But the registration-process actually sucks… big time! I was waiting about 48 hours to get my registration email including the activation link. Without activation, I could not use the keyboard. Arg… This is really annoying.

But the software works like charm. You can specify a color for every key, and you can reprogram every key! This is very important for Mac users, as you need to switch ALT and Window keys. And – this cannot be done in the keyboard settings of the mac – you need to change the key for the „menu“ key to ALT – otherwise you’re screwed 😉

Light show of the keyboard

Well, I was actually thinking about just having the backlight in one color – all keys the same. Of course, this is not the use of an RGB-backlit keyboard. But as mentioned above already, I think the profiles are very useful. Each profile stores different lighting effect (for each key individually) and different Macro settings. Even the keyboard may change between profiles. Switching between profiles can either be done by hitting FN+Number (depending on what is configured in Synapse 2.0), or depending on the current active Application! This is really awesome! Different lighting effects and different macro settings per Application – this is really useful, not only for gamers! Especially not for Gamers, I’d assume. But this depends, on personal use… I definitely love it.

The other lighting effects are somewhat… juvenile, if you know what I mean. It does not make really sense to show the siluette of Mario (of Mario Bros) on your keyboard, while typing. This is just for showing of at LAN Parties or alike. Especially effects like the „Ripple“-Effect where a wave of a certain colur rippels over your keyboard, is especially un-useful. If you type more then two keystrokes a second, you will just end up with a fully lit keyboard.

But I have to admit, these lightshows are fun to look at. And even fun to program them and play with them… maybe not enough reason to buy the keyboard, but definitely a gimmick.


When you get the keyboard, you’ll first notice, that there is quite some weight. And that is a good thing. The keyboard lies rock solid on my desk, does not move an inch when typing. Love that.

The typing is really similar to typing with MX-Blue switches. The sound is also very alike. I could not tell the difference just by hearing it. The keyboard feels quite good, feels high-class. I hear that people tend to say that Razer keyboards would have a cheep feeling, or would use cheep components. And although they don’t use the original cherry switches, it really feels alike.

I only use the keyboard about a week now, but I really like it. The typing is a lot easier and faster here than on the usual rubberdome keyboards. I love the typing experience. And the backlighting is quite cool! Just looks awesome! I configured my keyboard to have different key colors depending on which application I am just using. This is very helpful. Actually even more helpful than the backlighting alone. I’m really happy that I got an RGB-Backlit keyboard. This features is something I’d really miss on other keyboards.

Example: I am developing very often, sometimes in the dark. When I sit there, the keyboard is in front of me, not really „under“ me. So, when I need to find the right F-Key for doing the job (debugging for example), I find it very helpful to have those keys lit in different colors: Green ⇒ Run, Orange ⇒ Debug, Blue ⇒ Step over, Yellow ⇒ Step into

Although those features are „Gamers“ features, I really like them not only for gaming. Or better: especially not for gaming.

I heard, there will be an API or SDK for programming the keyboard directly. Of course again this is aimed at game developers. But maybe it is possible to write some useful things for us developers there as well (like: in your IDE, when actually debugging, change the color of some keys, change macros etc)

Of course, there are some things that are not that good, I have to mention as well. For example the indicator lights for „Gaming Mode“, Caps Lock, Macro recording and such. These are above the number pad and are so faintly lit, that you almost cannot see them, especially when the rest of the keyboard is lit bright. This really looks like they never used that switches at all.

Although the backlight itself is very cool and looks awesome, it is really strange that the keys are somewhat selectively lit – for example the very important FN-Key does not shine through. You won’t be able to read it, when it’s dark and you depend on the backlight feature. Same with the multimedia functions on the F-Keys. Does not shine through, not visible in the dark. Or even the Shift-Symols on Number line, like !“§ etc. not shown. Strangely, the additional Braces []{} are shown… this is inconsequent and not really understandable.

There are some reviews in the internet, that the keyboard would produce errors after a short amount of time. I will hope, mine won’t show these kind of errors. If so, I will post an update here. I really like the feeling of the Blackwidow and really like typing on it. It is way more fun, than I thought it would be.

So, if you are looking for a new keyboard, even Gamer keyboards might be worth a try.

Update after one month

I still like typing on the Razor Blackwidow Chroma – a lot! But there are some issues, I’d like to share:

  • it is a shame, that Synapse forces you to be online. Sometimes I have to disable the firewall rule in order to have Synapse „call home“. Otherwise it would not start up
  • When the Mac is awaking from hibernation (or sometimes even from Screensaver), the blackwidow would not come up „completely“. Meaning, some keys just don‘t work at all. They are not reakting on your reactive lighning animations and – of course – the corresponding key is not working at all. When this happens, you need to disconnect the Chroma from your Mac completely and reconnect it – usually the Keys work fine after that
  • I did not manage to geht the <|>-Key (lower row, left, besides the y) to work at all! It would not fire an event to the system! I managed to get it to work somehow with Karabiner and setting a macro at this key

All in all this lowers the good first impression a bit….


I use the chroma now for about 2 months and typing on it is a pleasure, gaming with it also… I love the opportunity to change the backlight with every game. Really cool…

Today there was an update for the Synapse software. And I was hoping to get my issues with the <>-Key resolved. Well, was hoping for too much. Actually, I was hoping things would work as they used to! But here also – hoping for too much.

The update is really somewhat annoying. The Razer-Updater freezes for a couple of minutes. I was tempted to force quit it, but it came back. This could be done better @Razer!

Problem gets worse: After the update, the synapse detected my keyboard as a US-Version, there is the key <> missing at all. And this caused problems. I restarted the app and voila – had to relogin and all my settings were gone! Comletely blank configuration, all macros, all backlight configuration, everything just gone!

Here is my tip: Export your settings from time to time, than you wont lose your macros – but the lightning seetings are gone!

I am in contact with some guy from the razer support. I told him, that the key actually works in synapse, that I can assign macros to it. But that is something, he does not want to understand. So the first 3-4 mails I told him, that this is probably not a hardware related issue.

Nevertheless, there was no help from the razer support yet, although there were about 10 mails send in both directions.

After the latest update, now the right ALTGR and Application keys are not working anymore. I wanted to reassign them in the synapse software, but if i map them to left command / left alt, they are fireing both alt and command when pressed. This renders the keyboard almost useless! Hope I can get a fix soon….

ErgoDox EZ in German on a Mac

2015-05-22 - Tags: ergodox ergodox-ez keyboard keyboard tastatur

The ErgoDox EZ in German on a Mac

This introduction and review is already available in German here. Yes, I admit, I was following the Indiegogo campagne of the ErgoDox-EZ quite a while. And since about 5 days now I'm a proud owner of an ErgoDox-EZ keyboard! Details about the campaign and the ErgoDox-EZ can be found here.

Unfortunately the keyboard was designed for the english speaking areas and does have it's issues with international layouts. Hence it also has problems with the German layout - that means, when setting the operating system to German, the keys are not at the place they should be. At least not with the default firmware. Most of the special characters were "somewhere" on the keyboard - ok, that could be learned. And you need to get used to this keyboard a bit. But some of the umlauts (öäüß) were spread around the keyboard as well. This made fluent typing (if you're touch-typing you know what I mean) nearly impossible. Well, the internet states this keyboard is fully programmable, everybody can make his own layout. Ok, this was not as easy as it sounds, but not as hard as it could be. Especially because I did not only want to fix the German layout, I also wanted to address other issues as well:

  • as already mentioned, the umlauts were spread across the keyboard, often in the lowest row of keys. They should return to the usual QWERTZ-location
  • I did have problems with the space key only being on the left side of the keyboard, as I'm typing space with both thumbs. (update: after using that, I learnt that having space on the right, having backspace on the left works way better!)
  • the location of CMD-keys was a bit bad * the ALT-keys were also a bit awkwardly located
  • I liked the idea of different layers, but the "Coder"-layer was not working with a German layout - about 70% of the keys were just sending the wrong keycodes (sometimes even umlauts) - that means, that about 70% of the keys were actually there, but at a wrong place. And the places were mixed up a lot. So, this thing is so greatly programmable, I read. let's go - how does that work? Well, this was kind of a setback, as this was not easy to find. There are a lot of github projects and forum discussion around the ErgoDox, but not really a simple howto. Thanks to Erez Zukerman (he initiated the indiegogo campagne) and that he replied after just a couple of hours after each of my questions (including the different time zones!), it did not take that long to get into the topic. Now, compiling a new custom firmware for the ErgoDox-EZ is no big deal anymore.

Disclaimer: what I describe here, are my findings, things that worked well for me. I'm not claiming this to be complete, or fitting for everybody (e.g. I cover only OSX German here). And, of course, this is probably not free of errors and faults. So, if you use these information, it's your responsibility. And please, read further documentation.

DE-Layout for the ErgoDox EZ on a Mac

I try to address all the issues mentioned above and created a first version of such a layout - it can be downloaded

here. Feel free to test it... This is what the layout looks like: There are some features I'd like to point out:

  • There are 4 layers in total, default layer (all normal keys), symbol or coder layer (containing all kinds of brackets, symbols etc which come in handy when coding), the media layer (there you can control the mouse and it contains multimedia keys like play/pause, volume up/down...) and last but not least a number block.
  • All umlauts are at their usual location * Because the umlauts are at their usual location, some of the special characters had to be moved to the lowest row of keys (like #)
  • the cmd and alt keys are now in the middle of the keyboard (on both halfs), CTRL is where the upper cursor keys were located. So, CTRL, CMD and ALT are located in a vertical row on the "inner" edge of each half of the ErgoDox EZ.
  • There is a space key on each half located in the thumb block
  • the tab and ESC-Keys were moved to their default location
  • the Caps-Lock-key is a layer switch now (as I don't use Caps-Lock at all)
  • several keycodes (like CTRL) are defined on multiple locations due to several reasons: sometimes I like to type for example CTRL on the right, sometimes on the left half of the keyboard, depending on the context. and I did not always know what to put at a certain key - too many keys there :) As already mentioned, this is a layout that works for me quite ok now. I will probably improve it over time (fortunately that is possible). It is opensource and available in github. Maybe you have additional ideas, how to improve things. Or you create your own custom firmware. But this is just the beginning...

Beginners guide / howto for ErgoDox on a (german) Mac

As we speak about beginning. I did not find a good howto, how to start with the ErgoDox-EZ on the Mac, especially with a mapping the keys and such, creating a custom firmware. There is an english wiki being created right now

here. No real how to or similar. But there are actually not many steps necessary to alter an existing layout, compile a new firmware and finally upload it to the ErgoDox-EZ (sometimes called "flashing" the device). But before we get to that, let's just explain some terms you'll read all the time when looking for information about the ErgoDox.

ErgoDox vs ErgoDox-EZ

The ErgoDox keyboard is already available quite some time now and could be ordered at Unfortunately, it was necessary to build the opensource keyboard yourself. That means, you'd get a lot of parts, you need to put together, soldering them , build a case, etc... And this is not working for everybody, as some of us do not have the time for such a DIY-project, or simply lack the knowledge and craftsmanship. And: if a little mistake happens, you end up with a really beatuiful, but not working keyboard. This is where Erez Zukerman comes in - his indiegogo project addresses exactly that by creating a real product out of an opensource DIY-keyboard. A product, you can buy, like any other product, including warranty and support. But still: everything still is opensource, including the things that are built right now especially for the ErgoDox EZ (like custom firmware)


At the first version of the ErgoDox (not EZ!) could be bought. As mentioned above, this was just a bag full of parts, you needed to do all the soldering and building it up from scratch. But at massdrop you get a configurator which is capable of creating .hex files directly and visually. You can create your layout there and end up with a file you can directly flash on your ErgoDox. There are some issues when it comes to non-standard keycodes, though. So I did not find a way to do the

long type or other special functionalities there. That's why I took the manual approach. If you only need a simple layout, without fancy stuff, the configurator on massdrop might be the easiest way to create a working .hex-file.


This actually is the hardware the ErgoDox (and the ErgoDox-EZ) is built upon. This is not very important, only if you wanted to build an own custom firmware from another code base. You also need to upload the firmware to the ErgoDox, if you want to change the layout. On a mac you can use the tool

teensy loader, which is named after the hardware. This tool takes some .hex-files and uploads it to your ErgoDox. You can download your copy here.

QMK Firmware

This is the standard firmware for the ErgoDox-EZ. You can guess by the way I'm saying that, that there are probably some other alternatives out there. And on github you can find some of those. I did not dive into that topic yet, I'll stick to the "original" for now.


As already mentioned above, the firmware for the ErgoDox-EZ (or more precise for the Teensy Microcontroller) es stored in .hex-files after compiling. Only those files are needed. When you compile, you end up with a whole bunch of new files (like .sym, .obj and alike) which are not really necessary. You only need the .hex file.

How to install a new firmware

This is rather simple if you already have a proper firmware file in .hex-format. Some examples of those can be downloaded from the official repository here. This is the firmware project repository for the QMK-Firmware - there is a subdirectory ´keyboard/ergodox-ez/keymaps´ where you can find some of those .hex-files. My version of the layout can be downloaded here. To install this file, you only need to follow these easy steps: 1. Download the .hex file (if you compile it yourself, you end up with such a file also) 2. Open the App Teensy Loader (see above - Teensy). Then take a paperclip and klick the button on the keyboard on the upper right (there is a little hole in the case). This brings your ErgoDox EZ into programming mode. 3. Open the .hex file (first icon from the left - looks like a document icon) 4. To upload (aka flash) the firmware file to your keyboard, click on the 2nd button from the left ("rounded" Arrow). You'll see a progress bar during the upload process. 5. now klick on the reboot button (small arrow, 3rd icon from the left) After that, your new firmware is installed and used. You should see your changes now. I experienced some kind of "failures" after the reboot, like, the keyboard was stuck in a certain mode, the left half of the keyboard would not react... but I could fix it by just unplugging it and replugging it after a couple of seconds. I flashed the ErgoDox-EZ now about a dozen times, and in maybe a 3rd of those cases, an error like described happened. All could be fixed in no-time. So, don't panic!

howto create your own firmware

To do this, you need to do some preparations. As already mentioned I only consider MacOSX here - I did not try the ErgoDox on Linux or Windows. You should install If you have macports installed, you might end up with an error. We need to install a so called cross compiler. This is a compiler, that produces code not for the hardware it is currently running on, but something completely different. In our case this is the Teensy 2 microcontroller. If you use macports you'd have to find, how to install this crosscompiler. With ´brew´ the installation is just a few lines: brew tap osx-cross/avr brew install avr-libc after that you need to checkout the project from github. Details you can find there, but this is the command, you need (creates a folder in current directory):

git clone
 now go to the directory 

qmk_firmware/keyboards/ergodox_ez. for testing, you should run make there, this will create the default layout .hex file in this directory. The file is called ergodox_ez.hex. If you end up with an error message, take a close look. Probably you only need to install some tools or something. If you want to create a different than the default layout, you need to store the name of your layout into some environment Variable: export KEYMAP=osx_de if you run make now, this layout will be created. If the corresponding C-File exists in the directory

keymaps (here the filename is keymap_osx_de.c. You can easily change an existing C-File, create a completely new one (not recommended), or copy an existing C-File and alter it to your liking. You only need to change the environment variable accordingly. If you need additional information about what possibilities you have with this C-Files and what is possible, have a close look at the project documentation. I really hope, this little howto is helpful for you and your new ErgoDox-EZ!

Features of the ErgoDox-EZ - layout programming details

As you now know, how to compile and upload a new firmware, let's have a look at the features, you might use in those firmwares. I call the process of defining the layout for your keyboard in C-Files "layout programming" - it is not real programming, although there a datascructures involved, some C-experience is surely beneficial. But it is not real programming... you usually do not need to do loops, if-then-else or something. But you need to know some things.


First, every key can be programmed so send any keycode a keyboard might have (and actually mouse also). So, it would be possible, to change the position of keys completely (e.g. DVORAK, NEO or ADNW layouts. All alternatives to the existing QWERTY/Z layout). You could also create a special layout for a special purpose. Like a special software, where you actually do not type a lot, but really use hotkeys and shortcuts. (like in a game or other special purpose software, CAD, PhotoEditing... whatever you use). In the QMK-Firmware, every of those layouts needs a corresponding C-File (see above). In this C-File there is the layout defined as an array of 64bit integer values, every

place in this array determines the key, the value of this determines the keycode that is going to be send from this key when pressed (or released...). Imagine the keys are numbered from the top left, to the bottom right, each half of the keyboard separately. So in my layout, the first keycode in this array defining it is the ESC-Key. The name for that in the C-File is KC_ESC. All "raw" keycodes have the prefix KC_, there are international definitions of keycodes also with their corresponding prefix for the country (like, DE_), but in my case, those keycodes were meant for Windows, not OSX. But that is no big deal, just think about what you would type.


You can have several of those layouts defined in the c-file. Actually, the data structure is an array of arrays, the latter ones defining a layout each. So, when you switch between layout, you can completely redefine the whole keys (with one exception - the key you use for switching between layers, see below) There is one keycode defined, called KC_TRNS, which actually is no real keycode but telling the firmware, "if this key is pressed, use the keycode from the layer below the current one". This does not work with the first (base) layout in your configuration, because we need to have something defined to fall back on. So, when you start up the keyboard, you start with that layer 0, the base layer. When you hit one of those layer switches, you switch to a different layer, lets say layer 3. That means, layer 3 is on top of layer 0. If you have any keys defined as KC_TRNS in layer 3, pressing one of them when switched to that layer, acutally issues the keycode from layer 0. And to make things a bit more complicated: you can actually stack those layers. You could define a layer switch with one key, pressing anotherone will add a layer to that stack. KC_TRNS will then fallback to the layer below in the current stack. This feature could be used, if you need a similar behaviour like with ALT and SHIFT. Think about it: when you Press shift, the keys switch all to upper case, when you press alt, some special characters occur. But when you hit both, the layout changes again, at least for some keys. Acutally, this stacking of layouts is pretty standard. We just were not aware of it... With that you could create your own more or less simple layout, without any layers or any fancy features like long type or something. This is - at least as I understood it - what you can get from the massdrop configurator.

Special keypresses

But there are features, you might enjoy...

  • you can not only send a simple keycode, but also one in combination with a modifier (like shift, alt, cmd, ctrl... and so on). This can be done easily by adding for example LSFT to your keycode, LSFT(KC_7) would send a shift 7 keycode - usually the /. In this case it is actually pressing the left shift for doing that, but that usually does not make much of a difference.
  • you can make a key not sending a real keycode but making a switch to a different layer. in the DE-Layout this is actually done with the "Tab"-key, just switches to and out of the cursor layer. Please keep in mind: your layer-switch key, should always be defined to have the keycode KC_TRNS in the target layer, otherwise you might not be able to switch back. Toggling a layer on and of is done with the function TG(), as parameter you give the number of the layer you want to toggle, like TG(3) which would switch to your layout on index 3 (always starting at 0 (baselayout), this is the 4th layer!).
  • you have the option to define keys to behave differently when pressed long or just typed quickly. This is useful for modifiers. You can have the hyper key issued when pressed long, but when typed it sends a normal keycode. There are actually several ways of achieving this behaviour. First you can use the method LT() where in the brackets you add two arguments. First the layer it shoul switch to, when pressed long, the 2nd one is the keycode to be issued when typed. The other way is to use functions with the suffix _T, like CTL_T(). This one means, issue the keycode for control when pressed and held, but send the keycode given as argument, when typed. In my layout definition this is used for the Y and Minus-key to be also used as CTRL. Which comes in quite handy some times. with that you can define quite some layout - take a look at the baselayout for the osx_de version:

    //Base layer KEYMAP(

        KC_ESC,                  DE_1,         DE_2,   DE_3,   DE_4,   DE_5,   DE_6,
        KC_TAB,                  DE_Q,         DE_W,   DE_E,   DE_R,   DE_T,   KC_LGUI,
        KC_LALT,                   DE_A,         DE_S,   DE_D,   DE_F,   DE_G,
        KC_LSFT,                 CTL_T(DE_Y),  DE_X,   DE_C,   DE_V,   DE_B,   KC_LALT,
                                                                        M(M_MEH_SH_ACUT),       TG(2),
                                                                        KC_BSPC,KC_DEL,         LT(SMLY,KC_END),
        // right hand
             M(M_CTRL_CMDC),  DE_7,   DE_8,   DE_9,   DE_0,   DE_SS,            DE_HASH,
             KC_RGUI,     DE_Z,   DE_U,   DE_I,   DE_O,   DE_P,                 DE_UE,
                          DE_H,   DE_J,   DE_K,   DE_L,   DE_OE,                ALT_T(DE_AE),
             KC_RALT,     DE_N,   DE_M,   DE_COMM,DE_DOT, CTL_T(DE_MINS),       KC_RSFT,
                                  KC_LEFT,  KC_UP,KC_DOWN,KC_RIGHT,        LT(SYMB,DE_PLUS),
             TG(4),       ALL_T(DE_ACUT),
             KC_PGDN,KC_ENT, KC_SPC

One additional thing you should consider. When you have more than let's say two layers, it would be very useful to show the user, which layout is currently active. This is best done using the 3 different LEDs on the keyboard. To define that, you need to have a look at the method

matrix_scan_user. There you can do something depending on the currently active layer. In the case of the osx_de-layout, it looks like this:

void * matrix_scan_user(void) {

  uint8_t layer = biton32(layer_state);

  switch (layer) {
    // TODO: Make this relevant to the ErgoDox EZ.
    case 1:
    case 2:
    case 3:
    case 4:
        // none


I think this is more or less self explaining. The every case statement defines what to do for each layer. So for layer 0 (not listed here) all LED will be off. For layer 1, the led 1 will be on (the red one)... and so on. This function is called periodocally in a loop, so there you could add any other custom code, if you liked. These are the major features, I needed to implement my layout. There are more features, that might be useful (like stacked layers), but for now things work fine. I will work on improvements, if you have any suggestions, just leave me a note...

ErgoDox-EZ - Should you buy it?

Actually, that is a tough question. I think, it was worth it. But I use the keyboard only a couple of days now. I was quite fond of my "Razer Blackwidow" also and that changed over time. In this very moment when I'm typing this text I can only say, it feels very worthy, the switches feel like Cherry (but they aren't), the feedback is good as expected from a mechanical keyboard. Of course these switches do make som noise, you do not only get tactile feedback, but also audible one - I like that noise, but this is maybe not everybodys way of working. I installed dampener rings on the keys in order to reduce the sound wen typing through. But I actually like this "noise" a lot and it motivates me. But that is my personal opinion. And I ordered the ErgoDox-EZ with that Switches that are comparable with the Cherry blue ones, but there are different options. For me the ErgoDox-EZ is very close to the perfect keyboard. There are some things that might be missing (LED backlighting maybe). But I really like it. Right now, I like typing with the ErgoDox-EZ, it also helps me to go easy on my elbows and wrists, which are somewhat aching after a long day. This was one major reason in getting an ergonomic keyboard. I will maybe also create a ADNW-Layout (neo2 based layout, optimized for German and English typing), but that is a very different thing....

Update after one week: Still like typing a lot with the ErgoDox. Especially as i got my custom layout up and running. It makes things a lot more smooth. Typing is a breeze... Also, I have to say, the support from Erez and his team is great! Thanks again. I am really astonished, how quickly I could adjust to the new keyboard. After just a couple of days, it really felt awkward typing on a normal keyboard again. This actually is a good sign!

update after some weeks of use

I got used to the ErgoDox quite fast. Really still like typing on it. And I learned some things about my own layout: having space on both sides of the keyboard is actually not that great. I miss having the delete key easily accessible. So... I removed the space key on the left side of the keyboard and replaced it with backspace, putting the current backspace to be a DEL-key. This seems to work ok... And: I really was not using the CTRL-keys on the upper row. Used the keys on both pinky fingers for CTRL. That works better actually. I put CMD-C / CMD-V there... at least for now. Maybe I'll experiment with macros there... Did not come up with a better solution for that... Also still looking for something useful to put on the Caps-Lock-Key... right now its only a mode / layer switch. Did not come up with something fancy for that yet.  

Annother update - one month in to 2016

I really like typing on the ErgoDox EZ, it feels great, I'm quite fast and my layout seems to be working fine now for me. Although I needed to add some additional features:

Smiley Macro Layer

I thought I need to play a bit with macros and wanted to put some things I often type there. So I decided to create a smiley layer. This is available in the currently merged version of the firmware. When pressing the lowest, rightest key on the left halfs keyboard thumb block you temporarily enter this layer and can type smileys with the right hand side! Works like charm! 😉 :-D EgoShooter Layer The default layout I have created is optimal for typing (at least for me) - but it did not work at all for EgoShooters like Counterstrike global offensive or alike. I had to create an additional layer. But I did not want to waste a key just for switching to this layer, and - obviously - did not want to have a key pressed all the time in order to be "temporarily" in that layer. I wanted to switch from one layer to this new layer and only there... Right now, when enter the symbol / coder layer you can switch to the ego shooter layer by typing the top left key on the right keyboard half. Then all 3 LEDs will be on indicating that you are ready to go for some serious ego shooting ;-) The changes are more or less minimal: * left side backspace becomes space * left side delete becomes control * left side < / symbol layer switch becomes Ctrl * the outer thumb keys on the left side become F1-F4 maybe there will be some additional changes to this, but right now, it seems to work quite good. Happy fraggin'

** Another Month - another update **

Still love typing on the ergodox, but I start feeling uncomfortable writing on a "normal" keyboard. I had to install the "reinforcement kit" last week, as I got one of the ErgoDox-EZ' with a slight fault (look here)

For some reason, I did not like having the numbers on the right side starting with 6, I wanted them to start with 7. So I changed the layout to reflect that. That works fine for me and has some advantages:

  • I could put the # to the top right key
  • I could put the F12 there as well
  • the 6 is now on the left side, top rightmost key. This was CMD-V before. Missing that to some extend. I'll have to have a look for that.

as some time went by, here is a new update again

I played with the layout a bit again. I did not like the asymmetric shape of the numbers, and it did not really work well. I changed a lot of things today:

  • moving cursor key layout back to the "deafult" ergodox
  • adding ISO-Cursor keys to the symbol layer
  • adding a CTRL-SHIFT key on the rightmost, topmost key on the left half
  • needed to move the # somewhere useful. Put it on the topleft key on the right half
  • some fixes, especially adding a , to the number pad. This caused problems with typing some numbers already

maybe this is the best layout for my case. I was astonished how hard it is to get rid of the "used" positions of keys. And I actually do not like to move things to totally different locations - this would mean I cannot type on an usual keyboard anymore fluently. And this is not working with carrying the macbook from meeting to meeting.

really like playing with the programming of the ergodox! this is fun. And it will improve the layout over time. Still need to find some way to build these layout pictures somewhat more easily - right now is's pain!

** Update on documentation **

The layout went through some iterations till today and for now it seems to be ok. Go check it out at github. There is also a new Project I created that (for now) helps me createing a png of the layout so that you get a better overview. Later this might be used to create layouts as well.

Check the post here and the github page here

the current layout looks like this:

OSX 10.10 Yosemite & iOS 8 - erste Erfahrungen

2014-08-13 - Tags: osx

no english version available yet.

Natürlich musste ich mir auch ios8 installieren, wo ich doch schon mit Yosemite ganz gut fahre. Wobei so langsam einige kleinere Bugs auftauchen. In meinem letzten Post zu dem Thema habe ich ja schon einige Bugs erwähnt, es kommen aber noch einige dazu, insbesondere in den Einstellungen stimmt die Ansicht nicht immer mit den wirklichen eingestellten Werten überein.

Continuity und HandOff

Was allerdings wirklich nervig ist, ich schaffe es nicht meinen iMac mit meinem hier im Büro erstellten Wlan einzuhängen. Er geht nur über Kabel ins Netz. Das ist auch der Grund, warum Continuity und Handoff hier nicht funktioniert, denn dazu müssen die Geräte ja im selben WLan sein – IP-Netz reicht offensichtlich nicht aus.

Hier ist es so, dass alle Geräte, egal ob über Kabel oder Wlan angeschlosen im selben Subnetz sind. Anpingen der Geräte untereinander funktioniert, allerdings weigert sich der iMac seit Yosemite standhaft, sich ins Wlan einzubuchen.Roblox Hack Free Robux

wobei das nicht ganz stimmt, er bucht sich ein, bekommt aber keine IP-Adresse. Auch wenn ich die manuell vergebe, funktioniert kein Datentransfer, nicht mal Ping funktioniert – da stimmt wohl was mit der Verschlüsselung nicht

Ein test mit einem Apple AirPort Extreme hat dagegen reibungslos funktioniert. Klar, dass die neue Software erst mal mit der Hardware aus dem eigenen Hause getestet wird. Und auch klar, es ist Beta Software. Und da MUSS es ja noch Bugs geben… Insofern alles ok.

Neues Feature: Markup

Ein Feature, dass ich im letzten Post unterschlagen habe ist die neue Markup Funktion in Mail. Wenn man ein Attachment in eine Mail hinzufügt, kann man (je nach Dateityp), Markierungen in der Datei machen (wenn es sinn macht – bei Audio-Dateien geht das nicht. Bei PDF, PNG’s etc sehr wohl).

Wenn man das oben gezeigte Menü aufklappt und dort auf „Markierungen“ geht, kann man in der Datei (hier ein Screenshot) „rummalen“… allerdings funtkioniert das etwas besser als „üblich“. Normalerweise sehen mit der Maus gezeichnete Markierungen meist aus wie das Gekritzel eines 3-Jährigen. Hier jedoch werden die eingegebenen Formen erkannt. Apple Mail macht da auch einen recht guten Job mit der erkennung. Meine „Kreise“ sehen mit der Maus gezeichnet wirklcih eher krakelig aus, aber Mail erkennt den Kreis. Auch Dreiecke und Vierecke funktioineren ganz gut.

Macht man eine Linie und am „Ziel“ einen Spitzen Winkel erhält man einen Pfeil – meist etwas gebogen. Aber nachbearbeiten kann man ja auch immer noch.

Des Weiteren kann man auch seine Unterschrift (ähnlich wie das in Mavericks bei geht) einfügen oder Formen oder Text.

Bei der erstellung der Screenshots für diesen Post ist mir genau diese Funktion allerdings mehrmals abgeschmiert. Läuft also noch nicht ganz Rund das mit dem markup. Aber die Idee ist super!


Das Update hat auf den ersten Blick recht wenig neues gebracht (fotos dazu gibt’s ja zur Genüge). Klar, die neue Tastatur bemerkt man recht schnell. Aber sonst sind sich iOS7 und 8 sehr ähnlich. Man kann nicht auf den ersten Blick einen Unterschied ausmachen. Erst die Details machen es.

Stabil scheint Die iOS8 Beta 5 auch zu sein – zumindest auf meinem iPad funktioniert (fast) alles reibungslos. Ein paar Kleinigkeiten klemmen schon noch, wie z.B. dass die Multitasking-Bedienung nicht immer funktioniert oder das einige Apps nicht wirklich kompatibel sind. Aber das wird sich sicher noch ändern.

Da einzige, was wirklich auffällt, ist die neue „Tipps“-App. Da werden einem ein paar Hilfestellungen für den Umgang mit iOS8 gegeben. Die spotlight-Suche wurde auch verbessert und macht was her….

die Erinnerungen-App ist jetzt etwas „Bunter“ aber vom Funktionsumfang her nicht wirklich „gewachsen“.

Neu ist natürlich auch die Möglichkeit, per iMessage Sprachnachrichten zu verschicken, Dafür gibt es neben dem Eingabefeld für den zu sendenden Text ein kleines Mikro. Tippt man da drauf, kann man eine Nachricht aufnehmen und dann versenden. Wirklich praktisch, wenn man grad nicht so viel tippen kann.

Siri soll angeblich auch leistungsfähiger geworden sein, aber das kann ich im Moment nicht bestätigen. Die Erkennungsrate ist bei mir genauso gut oder schlecht wie vorher und so wirklich eine Neuerung in dem Normalen Umgang habe ich jetzt nicht gesehen. aber das kann ja noch kommen.

Sonst ist iOS8 auch recht gut geglückt, die Stabilität ist für ein Stück Beta-Software wirklich ganz ok.

nie wieder 1und1

2014-08-07 - Tags: servicewüste

No translation available - this is an old entry from 2014!

Nie wieder 1und1

jetzt bin ich schon seit ziemlich genau 20 Minuten in der Warteschlange von 1und1. Und warum das ganze? Lasst mich von vorne beginnen...

Wie alles begann...

Ich war eigentlich Kunde bei 1und1 sowohl mit DSL als auch mit meinem Root-Server. Damals haben die mich echt geärgert und ich konnte den DSL-Vertrag nicht kündigen obwohl ich ca. 8 Wochen weder Internet noch Telefon hatte. Das ist eine andere Geschichte... Der Root-Server aus dieser Zeit lief aber bisher eigentlich immer noch ganz gut... ich konnte nicht meckern. Irgendwann, weil ich nicht mehr so viele Kunden auf dem Server hatte, habe ich den Server in einen virtuellen Server umgewandelt. Auch im Zuge dessen ,dass der Root-Server schon in die Jahre gekommen ist (5 Jahre ist schon ein Alter für so einen Rechner). ##Root-Server zu VServer Der Umzug gestaltete sich 1und1-typsisch super umständlich. Es gab da keine Möglichkeit den Server direkt umzuziehen oder irgendwie eine Migrationshilfe (wie es andere Anbieter anbieten). Das ist ja eigentlich auch kein Problem, schließlich bringe ich den Provider ja um den lukrativen Root-Server, damit ich einen billigen VServer nehmen kann.

Aber die haben es einem dann doch schon extrem erschwert, den Umzug zu ermöglichen. Durch die Verzögerungstaktik verstrichen dann Fristen, was eigentlich dazu geführt hätte, dass ich den ROOT-Server noch 2 Jahre hätte behalten müssen. Zum Glück kamen sie mir da entgegen....

Dummerweise konnte man damals nicht die aktuelle Ubuntu Distribution 12.04LTS wählen, sondern nur 10.04LTS - Grund wurde einem nicht genannt. Irgendwann haben sie ihre software wohl aktualisiere und jetzt geht auch die 14er... aber damals hat mich das etwas nerven gekostet.

Der Umzug war dann doch irgendwann geschehen, und eigentlich lief alles gut.

##Vserver Der Server macht nun wirklich nicht viel, ein wenig Postfix, dieses Wordpress, ein kleiner IMAP-Server... das war es eigentlich schon. Das wäre alles kein Problem und mit den angebotenen 2GB locker zu handeln gewesen. die 50GB Festplatte reichten auch völlig aus.

ABER: der blöde server wurde immer wieder aus heiterem Himmel ohne ersichtlichen Grund runter gefahren. Und zwar nur der "Container" nicht die VM selbst. Auch beim meinen Zahlreichen Emails, Anrufen und Kontaktversuchen konnte mir keiner erklären, warum der Server runter gefahren wurde. Ich habe sogar von dem 1und1-internen Monitoring eine Benachrichtigung bekommen, dass die Dienste nicht mehr erreichbar sind.

Naja, das war zwar nervig, aber nicht unbedingt ein Grund den Provider zu wechseln und alles neu zu konfigurieren. Bis heute...

##nie wieder 1und1 Ich bin mittlerweile über 30 Minuten in der Warteschleife, konnte währenddessen den ganzen Blogeintrag hier tippen....

Das konnte mir einfach niemand erklären, warum dieser dämliche Container andauernd runter gefahren ist, bei einer mehrere Anrufe und Emails dauernden Suche nach Gründen, wurde zumindest die Ressourcenknappheit ausgeschlossen. Wie gesagt, normalerweise ist das kein Problem, man drückt in der Parrlalls Console auf "Play" für den Container und gut ist....

Normalerweise, nur heute nicht - der Play-Button ist disabled. Jetzt kann ich natürlich nicht währen der Arbeitszeit einfach mal 30 Minuten oder mehr in der warteschleife von 1und1 warten, bis die mal ran gehen ans Telefon. Deswegen habe ich, heute im Laufe des Tages zw. 8:00 und 16:00 insgesamt 4 Emails an den Technischen Support geschrieben.

Keine Antwort.

Keine Hilfe.


Nach ca. 35 Minuten hatte ich gerade einen Mitarbeiter der Hotline am Telefon. Der war zwar nett, konnte aber auch nix wirklich sagen. Ich soll doch in 20 Minuten noch mal anrufen, wenn seine "Diagnose" durchgelaufen ist. Dann können wir gucken. Wenn es dann immer noch nicht geht, "müssen wir ein Ticket für die Technik aufmachen"

Seit ca. 5 Minuten ist auch die Managemantconsole nicht mehr erreichbar - also irgendwas hat er gemacht. Nur ob es hilft ist noch nicht raus...

Heureka, nach ziemlich genau 15 Stunden und 57 Minuten ist der Server wieder online und alles ist "gut" - am Arsch!

Meine schlechte Meinung von 1und1 wurde wieder mal bestätigt, und deren TV-Werbung mit dem ach so tollen Support klingt für mich wie der reinste Hohn, da fühlt man sich doch als Kunde echt verar...

ich werde meine Domains jetzt woanders hin umziehen, fast egal wo...

Kündigen bei 1und1

Ich hab schon mal ein Paar der Domain-Verträge gekündigt. Dafür gibt es bei 1und1 eine extra Webseite (die man erst finden muss), wo man dann seine Verträge kündigen kann. Und weil man ja nicht einfach "so" mal kündigen kann, muss man natürlich auch noch mal anrufen. Aber bitte schnell, sonst können wir die Kündigung nicht bearbeiten.

Dort steht: "Sie erreichen uns zu folgenden Zeiten: DSL- und Mobilfunkverträge: Mo.-Fr. von 8 bis 22 Uhr und Sa.-So. von 9 bis 21 Uhr Hostingverträge: Wir sind rund um die Uhr für Sie erreichbar, kostenfrei aus allen Netzen."

Wenn man dann um 21:30 anruft, erhält man die Ansage: "Sie rufen außerhalb unserer Geschäftszeiten an. Erreichbar von Mo-Fr 8-20 Uhr, Sa. 9-19 Uhr"

Ohne Worte...


So long, and thank you for the fish...
