Posts Categorized: NetScaler

Every now and then it’s necessary to actually look into a SSL stream between client and NetScaler to inspect what’s actually happening. I struggled with this topic quite a bit, and documentation (eg. From Citrix) is not always complete. I will not pretend this document covers all, but I had some good successes decrypting traces with the following procedure. If you have any additions please let me know, and I will be happy to add them to this post.

So this is one of those topics why I actually started this blog. I’m preparing our environment for a big upgrade off all Citrix Receivers, implement Storefront and decommission our last two webinterface servers. A nice job which already gave me quite a headache. So in this tut I will try to give you the complete tutorial how to implement NSGW with Storefront so the Receiver can actually SSO, and all traffic is routed through the NetScaler Gateway.

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!

Momentarily I’m working a lot with NetScaler and SHA256 certificates. I noticed that with the change to SHA256 certs the NetScaler has some difficulties importing. The error you get is: Invalid private key, or PEM pass phrase required for this private key.

At this moment I’m using this command a lot so I thought it would come in handy to write a seperate article about it (easier to find). The command you use to convert a private key to PEM format is……..

In this tutorial I’ll guide you in securing your management page. The goal of the tut. is making sure the NetScaler Management Page is SSL encrypted and AD Integrated. Meaning you’re able to login with your Active Directory admin account. Let’s go!

At the moment I’m preparing for my CCE exam and one of the things I like to do is perform several setups. For this tutorial I implemented a XenDesktop & XenApp 7.5 server. A StoreFront server and a virtual NetScaler with a developer license. I already have in place a CA for my self signed certs, the domain joined machines automatically trust the Root CA cert and a Domain Controller is in place.

The goal of the tutorial is to get the StoreFront websites running on SSL. The XML traffic should be encrypted and the NetScaler has to connect to the StoreFront servers through SSL. Let’s start!
