There is a new and shiny NetScaler version available – version 12!
All the news and docs are available here, and you can download the latest bits from here. But, I will not write about them now – there is something else I would like to share.
Unlike with other (minor) upgrades, upgrading to this version… well, there were some “challenges”. If you have used Citrix NetScaler before, it has its nice and simple GUI, through which you can do many things… one of them being a system upgrade.
Upgrade process by using GUI is pretty straight-forward:
login to the appliance and save current configuration
if you are using virtual appliances, you can also do a snapshot or checkpoint (depending on the virtualization platform you are using)
go to System – System Upgrade and select the firmware file and click Upgrade
when installation completes, reboot the appliance
enjoy your shiny, new NetScaler 12 (upgraded in just 6 steps)!
And now about “the other way”…
As I’ve observed, upgrade option through GUI was not working (for me) in any of the major browsers (Chrome, Firefox, Edge or even Internet Explorer) – upload of firmware finishes and then… nothing really happens. Strange, but… it’s just my luck. No big deal!
So, you’ve finally decided to make yourself “a small Citrix lab” (XenMobile and NetScaler), but you’re having trouble with getting all the certificates in place. Fear not, I’m here to help!
Installing the SSL certificates for NetScaler is relatively simple, but still… some steps are easily forgotten and then… you need to troubleshoot.
Steps to install the SSL certificate for NetScaler (correctly) are:
Install the server certificate (for example, certificate for xms.yourdomain.com). The easiest way is to use .PFX certificate file, and you can install it through Traffic Management – SSL – Certificates – Server Certificates.
Install the issuing and root CA’s certificates (.PEM files are OK) through Traffic Management – SSL – Certificates – CA Certificates.
Create link (right click – Link) between the server certificate and issuing CA’s certificate.
Create link (right click – Link) between the issuing CA’s certificate and root CA’s certificate.
Check the certificate links on issuing CA’s certificate (right click – Certificate links). There should be two – one linking the server certificate, another the root certificate.
Select the imported certificate for NetScaler Gateway usage.
Select the imported certificate for (SSL) virtual servers as well. If you’re using NetScaler appliances in HA mode, force synchronization.
For XenMobile Server, there is some preparation work to do, to get it all right. Basically, you’ll need to combine all the (.PEM) certificate files into one, upload that to XenMobile Server, and restart.
Combine individual (.PEM) certificate files (server, issuing and root CA) into one .PEM file by following instructions on this DigiCert site (you can use Notepad to achieve this). Your final .PEM file should look like this:
As mentioned before, I was at the MobilityDay 2016 conference on Thursday, where I’ve had an honor to deliver a session about Citrix XenMobile & NetScaler solutions (yup, I know… it’s not Hyper-V… go figure… but my demo environment was still runnning on top of Hyper-V, so…).
Session was actually a short introduction to what Citrix XenMobile solution offers and how to set it all up, combined with NetScaler, for a complete management of mobile devices and mobile applications.
Conference was great, as always – so much old (and new) faces, with lots of fun. This time it was actually a 10th birthday of MobilityDay!
