So this is kind of nerdy but it’s also very cool. And poorly documented, so it’s nice figuring it out. Keeps me off the street 🙂 It is possible to use Google Authenticator as a second factor to authenticate to your NetScaler. And it’s not really hard to implement as well. So if you read Citrix’s blog about it you will see they’re using OpenOTP. The rest of the document is incomplete and give you very little instructions how to install. I will try to write a complete tutorial on how you can acchieve it. Let’s go!

So a short document on how to accomplish this (cause it’s easy… but cool!). You need to download three things. Putty, Xming and the Xming fonts. Just search Google and you’ll find the latest versions. Install Xming and the Xming fonts. It’s just a next, next, finish install. After completing start Putty.

So after following my tutorial about installing CentOS you’re facing your Linux prompt and wondering… Now what?? Well if that is your case you might need some graphics after all. I’m not a big fan of the Linux graphical tools cause they might ruin some of your configuration too. Eg. setup iptables and then modify something in the firewall tool. Say bye bye to your firewall config. Anyway, I today asked my Linux teacher how you can upgrade your existing installation with a desktop. His exact answer was: “I don’t know, but why should you? A new installation only takes 10 minutes…..” sigh. Like that was the question. So I did some googling and like many thing this one is well documented.

At this moment I’m attending a Red Hat Enterprise Linux system admin training which I must say is very interesting. I’ve always been interested in Linux but as a Windows minded admin never took the time to really learn it up until now. And I must say: LINUX ROCKS. In the past I ran into some hard-to-troubleshoot problems with Linux based systems and it’s nice to realize that things are now getting clearer. So I tought it would be a good idea to write a few tutorials for my blog, starting with the basics. How to install a CentOS (which is exactely the same as Red Hat Enterprise (only it lacks the enterprise support)) webserver which you can then use to host apps (like SickBeard/CouchPotato/Headphones/maybe some nzb-indexers (I’m full of ideas!!). I even took the time to take a lot of screenshots. So let’s start!
