Reading Time: 3 minutes

I already did a setup and installation of Citrix Licensing Server 11.12.1 here, but it is always nice to have a setup guide for a new version.

Adding a Citrix Licensing Server to your environmentÃ‚Â is important if you areÃ‚Â going to setup and useÃ‚Â Citrix products and solutions. So let me show you how to:

install the license server
configure the license server
add a license file to the license server

My environmentÃ‚Â for the installation:

downloaded the Citrix Licensing Server 11.13.1.2 (Build 16002) for Windows (www.citrix.com)
Windows 2012 R2
domain name: VIKASH (vikash.nl)
account for setup: Administrator (VIKASH\Administrator)

Installing Citrix Licensing Server 11.13.1.2

Unpack the .zip file and start the installer.

You will be presented with the screen below. Accept the license agreement and click on Next.

Choose your installation path and click on Next.

Next you will be presented by the port for the Licensing Server. Change it as you prefer, just make sure that it doesn’t interfere with services using those same ports on your server. Click on Next and the installation will begin.

After the installation has finished, you will be presented with a summary screen. I selected the option not to participate in the Customer Experience Improvement Experience Program. Make your choice and click on Finish.

Now it is time to upload your license. Go to the Start Menu and start the Citrix License Administration Console.

Your default browser will open with the correct URL for the Citrix License Administration Console. Click on “Continue to this website” to move past the SSL warning. We can fix this later, for now it is not important. Your session will be encrypted using the SSL certificate installed with the Citrix Licensing Server anyway.

Click on Administration.

You will be prompted to log on. Use your Domain Administrator (or the user used to install the Citrix Licensing Server) to log on. Click on Submit.

Click on Vendor Daemon Configuration in the menu on the left site. Then click on Import License.

Now click on Browse to locate your license file. Then click on Import License.

Click on OK after the import is finished.

The Citrix Licensing Server will only read the imported licenses after a reboot, or after the Citrix Licensing Server has been restarted. Let’s restart the license server. In the Run dialogue box enter services.msc and click on OK.

Locate the Citrix Licensing service, select it and click on the reboot icon in the menu.

Now switch back to your browser and reload (or re-open) the Citrix License Manager Console and go to the Dashboard. Your licenses should now be visible.

Airport

Apple Airport Extreme “disable” DHCP and keep NAT

March 16, 2016February 10, 2017 - by Vikash Jhagroe - Leave a Comment

Reading Time: 3 minutes

The Apple Airport Extreme is my home router and access point.Ã‚Â Recently I wanted to use DHCP on my Synology NAS and disable it on the Airport Extreme. Guess what, when you disable DHCP on the Airport Extreme, it also disables NAT! Not what I had in mind. I am a fan of Apple products, and wanted to keep using the Airport Extreme for my WAN -> LAN connection (internet), because I am pleased with the performance and stability.

There are only three options to choose from:

DHCP and NAT (which I am using currently)
DHCP only
Off (Bridge Mode)

See the screenshot below:

None of the options suited my needs, so what I found out is that IÃ‚Â can keep the DHCP and NAT option enabled, but deplete the DHCP servers IPÃ‚Â address scope. So basically I am going to setup my DHCP server on the Airport Extreme with a scope of two IP addresses and then immediately reserve those ip’s with fake MACÃ‚Â addresses. This way the Airport Extreme will not be able to serve IP addresses in my network, and I can now setup another DHCP server to fit my needs. In another post I will explain why I need another DHCP server.

Let me walk you trough the procedure using the screenshots below.

First let’s start by opening the Airport Utility, select your Airport Extreme Base Station and click on Edit:

Then go to the Networking Tab and click on Network Options…:

Setup the DHCP scope according to the settings in the screenshot below. The IP address space on my LAN is 192.168.1.x. You can have another range, adjust it to your needs. So I basically setup a DHCP scope consisting of two IP addresses. When you’re done, click on Save.

Now we have to add the fake IP reservations. In the DHCP Reservations section click on the + sign.

I then add Dummy 1 and Dummy 2 clients using a fake MAC address. Click onÃ‚Â Save

Now your Network tab should look something like this:

Click onÃ‚Â Update and that’s it! DHCP is now “turned off” on the Airport Extreme, and you are free to useÃ‚Â another DHCP server for more flexibility in your LAN.

HDX / HDX 3D Pro / XenDesktop

Thin clients and HDX 3D Pro support demystified

September 1, 2015February 10, 2017 - by Vikash Jhagroe - 3 Comments.

Reading Time: 3 minutes

Recently I was presented with the following case. I was migrating from a Citrix XenDesktop 5.6 environment to a Citrix XenDesktop 7.6 environment. The new environment was running XenDesktop VDI’s with Windows 7 on Citrix XenServer. Because CAD and 3D application support was a requirement, the customer decided to use nVidia grid cards and use HDX 3D Pro.

Everything was running fine in the new XenDesktop 7.6 environment (server wise) and I started testing with thin clients which the customer already had. The thin clients did support HDX 3D Pro according to the manufacturer, so we were good to go. After logging in to the virtual desktop using said thin client, I got the little icon in the task bar telling me that HDX 3D Pro was enabled. But the desktop graphics performance was very poor. It was lagging, slow and was absolutely not fast in response. It felt a lot slower then the XenDesktop 5.6 environment.

Now after investigation I found that these thin clients did not support the H.264 codec fully. Using the HDX monitor I could see that they were using Deep Compression V2. But the cpu of the thin client was being hammered to the max when working on the XenDesktop 7.6 VDI.

The old XenDesktop 5.6 environment was running fine, but the graphics were off course Legacy mode. So the next step now was testing without the nVidia vGPU support in the VDI and enable Legacy mode graphics. That means disable vGPU support in the virtual machine in XenServer, disable desktop composition redirection and enable Legacymode graphics in the Citrix policies. Still the graphics performance was very poor, and HDX monitor showed me that Deep Compression V2 codec was still being used! I was not alone on this, searching the Citrix Forum resulted in:

Contacting Citrix support they eventually told me that I also had to reinstall the VDA agent in the virtual desktop and choose the option not to enable HDX 3D Pro support during installation. When this option is enabled during installation, it is not possible to use Legacymode graphics. This worked, the Windows 7 VDI reverted back to Legacymode graphics and the performance on the thin client was now very good.

So now the next step was to find out what thin client really supports HDX 3D Pro. Not partial support for the H.264 codec, but fully support it so we know for sure that Deep compression V2 codec performance would be good. I found out that manufacturers brand their thin clients with support for HDX 3D Pro or Citrix Certified or Citrix Ready, but they were unclear of the actual performance with HDX 3D Pro. Then I found some information which made clear what the HDX and Certified for Citrix should mean:

Check out the website here. Ok, this makes sense. With this new information I started searching for thin clients which are HDX 3D Pro Verified and with this feature enabled. Searching the Citrix Ready Marketplace I found a list of thin clients which were fully certified for HDX 3D Pro! Check the list here. A few of them were already mentioned in a Citrix Forum post hereÃ‚Â (mentioned earlier).

So this is something thatÃ‚Â is a little bit of a grey area. Looks like thin clients enabled for HDX 3D Pro does not mean automatically a good performance in the VDI where HDX 3D Pro is a requirement. You have to test, make sure, and then re-test. Otherwise you and your customer will end up with very disappointing results, making you and Citrix look bad while it is the manufacturers of the thin clients who are to blame in not being utterly clear on what their product do support and what you can expect performance-wise (yes I am looking at you Dell).

This is my experience, and I could be wrong on this off course. What are your thoughts in this?

StoreFront

Basic setup Citrix StoreFront 3.0

September 1, 2015February 10, 2017 - by Vikash Jhagroe - Leave a Comment

Reading Time: 5 minutes

In this blogpost I will show the basic setup of Citrix StoreFront 3.0. StoreFront is the component for making your published desktops and published app available for your end-users.

A fewÃ‚Â new features of Citrix StoreFront 3.0:

unified user experience
improved customisation
loopback communications (no more host file editing)
treating published desktops as published apps
delegate authentication to backend servers

My environment for this basic setup:

Windows 2012 R2 (sf01.vikash.nl)
Citrix StoreFront 3.0 setup (www.citrix.com)
SSL certificate (storefront.vikash.nl) using own CA infrastructure (dc01.vikash.nl)
Citrix XenDesktop 7.6 Controller (xddc01.vikash.nl)

Before we can proceed with the installation we need a SSL certificate. For lab purposes I have installed a internal CA (my domain controller) and requested a domain certificate. Using Internet Information Services Manager on my StoreFront server I requested a domain certificate.

Make sure that you request a proper SSL certificate for production environments! Contact me if you have any questions regarding SSL certificates in production environments.

SSL Certificate request:

Open IIS Manager and click on create Domain Certificate:

Fill in the required information and click on Next:

Select the appropriate CA and set a friendly name for the certificate. Click on Finish:

We now have to bind this certificate to the Default Web Site on your Citrix StoreFront server. In my case this is sf01.vikash.nl. Start IIS Manager, expand Sites and click on Default Web Site. Then click on Bindings:

Click on Add:

Select https as Type and select the SSL certificate we just requested. Click then on OK:

Now we can see that SSL is enabled for the Default Web Site. Click on Close:

Now you can test the certificate by browsing to the default website of the StoreFront server:

If everything went well you should see no errors in your browser when requesting the page using https.

Installing Citrix StoreFront 3.0:

Start the setup by double-clicking onÃ‚Â CitrixStoreFront-x64.exe. Setup wil now start:

Accept the license agreement and click on Next:

The setup will install the required Windows Features and Roles. Review and click on Next:

Setup is now ready for install. Click on Install:

Installation in progress. Grab a coffee:

Click on Finish after installation of all the components:

Citrix StoreFront will automatically open and you will be presented with the Welcome to StoreFront screen. From here we can start the basic configuration of StoreFront:

Basic setup of Citrix StoreFront 3.0:

Click on Create a new Deployment:

Enter your Base URL. In my case it is https://storefront.vikash.nl. Click on Next:

Enter the Store name. In my case it is Vikash. Click on Next:

Now we have to specify Delivery Controllers so StoreFront knows where to get published apps or desktops. This is your XenDesktop or XenApp controller. Click on Add:

Enter a name for the Display name and set the correct Transport type, in my case it’s http. Make sure you select the correct version of XenDesktop of XenApp. Click on Add:

Enter the hostname of the controller and click on OK:

As you can see the controller has been added. Click on OK:

Click on Next:

Leave the defaults (None) on the Remote Access page and click on Create:

Click on Finish:

Now click on AuthenticationÃ‚Â in the left panel andÃ‚Â click on Configure Trusted Domains. By adding trusted domains the user can only set their username when logging in. This options also allows us to add multiple domain names as trusted domains and allow the user to select the appropriate one when logging in.

For now we have only have one domain. Select the Trusted domains only option, click on Add and enter the domain name (vikash.nl). Then click on OK:

Now click on Receiver for Web in the left panel and locate the Website URL. Time for some testing!

I will login using my test user (test01) from a virtual machine which is joined in my domain, so my SSL certificate will be trusted. Open the URL in a browser and enter the test user credentials:

The user is successfully logged in. I don’t have published apps or desktops yet. I show that in another blogpost. For now we have a working Citrix StoreFront 3.0 environment, ready for further testing.

You can also follow me on twitter or add the rss feed from the blog and you will be notified when I add new posts. If you have any questions feel free to contact me.

Provisioning Services

Basic setup Citrix Provisioning Services 7.6

July 4, 2015February 10, 2017 - by Vikash Jhagroe - 2 Comments.

Reading Time: 6 minutes

So I got some free time now to continue setting up my homelab. I decided to start with a basic setup and configuration of Citrix Provisioning Services 7.6 (PVS). I will be needing this component to stream my desktops and servers. Citrix Provisioning Services (PVS) eliminates the need to manage, update and patch individual systems. Instead it allows us to use a master image to provision computers. This master image (vDisk) can be used simultaneously by multiple computers.

In this post I will show you how to:

Install PVS
Basic configuration using the PVS wizard
Creating a farm

My lab setup:

Host running Citrix XenServer 6.5 SP1
Windows 2012 R2 server with patches and updates which I will be using to installÃ‚Â PVS
Downloaded PVS ISO fromÃ‚Â www.citrix.com
Service Account in Active Directory

Install Citrix Provisioning Services 7.6

Using XenCenter mount the ISO on the Windows 2012 Server VM and start the setup. The setup will start. Click on Server Installation.

If there are additional items to be installed, you will be prompted for them. Click on Install.

Click on YES.

Click on Next.

Accept the License Agreement and click on Next.

Enter your customer information in the User Name field and the Organization field. Select the option you need for “Install this application for”. Click Next.

Select the installation folder. In my case I left it default. Click Next.

Then click on Install to begin the installation.

Click on Finish the start the configuration wizard.

You will get a warning about the PVS console not detected on your system. Just click on OK, we will deal with this later.

The configuration wizards start, click on Next to begin configuration.

Configure the DHCP options according to your infrastructure. I have selected the option “The service that runs on another server”. Select this option is you have a separate DHCP server installed. Click on Next.

For the PXE services I have selected “The service that runs on another computer”. This is the scenario I see in most of the cases with customers running PVS. In many cases they have a seperate PXE server running for Thin-Clients. Select the option you see fit for your infrastructure. Click on Next.

Now we have to create the PVS farm. In another post I will cover the “Join existing farm” option. For now let’s create a new one. Click on Next.

Enter the information to setup the PVS database on the SQL server. Select the appropriate instance, otherwise leave blank. Click on Next.

In the New Farm windows enter the information according to your company/infrastructure. It will already suggest the database name. You can change it, or select the appropriate database. I also added the Active Directory Administrators group. Click on Next.

Enter the Store name and the path where you vDisks will be stored. Click on Next.

Enter the hostname or ipadress of you licensen server. I also checked the option “Validate license server version and communication”. Ã‚Â Click on Next.

Enter the service account you created in Active Directory to setup the Stream and Soap services. This service account will also be used to setup the database. Note that this user must have db_writerÃ‚Â and db_reader access, so I made this account the owner of the PVS database. Click on Next.

I use the default to updateÃ‚Â the computer password in the Active Directory. Click on Next.

Select the network card for management and streaming, in my case there is only one. Check the communication ports. I left them default. Click on Next.

I choose not to install TFTP server, as I will be booting using an ISO. This ISO tells my client device (target) where my PVS server is. I will cover this in a later post. Click on Next.

Check the information on the overview screen. Click on Finish.

You will get a notification about the firewall. Click on OK.

Now wait for the wizard to complete the configuration. It should end with all the green checkmarks. Click on Done.

Install Provisioning Services Management Console

Now we need to install the PVS Console for management purpose. This console can be installed on a remote server (like a management server). I choose to install this on my local PVS server.

Start the setup from the Provisioning Services installation ISO. Click on Console Installation.

Click on Next in the Welcome screen.

Accept the license agreement. Click on Next.

Enter your customer information in the User Name field and the Organization field. Select the option you need for “Install this application for”. Click Next.

Choose the installation folder. I left mine default. Click on Next.

Select the setup type. Click on Next.

We are now ready to install. Click on Install.

Click on Finish.

Start the PVS console and enter the information of the PVS server. Click on Connect.

We now have a working Provisioning Services server. In another post I will show you how to create and configure master images using Provisioning Services.
