Introduction
Its my 5th #CitrixSynergy and this is def one of the best Synergy’s I have ever had the privilege of watching virtually from London, England. Why not in person? I prefer to watch virtually as I am to consume more content faster and translate that into content to update Citrix partners/customers in a timely manner at high level and tech deep dive where required in particular areas or topics. Finally this blog post will most likely change over the next 2-3 weeks as I consume all of the Synergy 2017 content as when/how I can.

My New Secure Workspace Ready in less than 15 min the #CitrixLife

The views expressed here are my own and do not necessarily reflect the views of Citrix.

Overview
Today I received my new Mac, yes I’ve decided to move from a PC to a Mac for various reasons (those whom know me are probably going really!?) but I still have a Windows 10 tablet PC which I use regually at home, but most importantly my Windows 10 Citrix issued virtual desktop powered by XenDesktop (Citrix on Citrix) follows me anywhere with Citrix Receiver or the HTML5 Citrix Receiver!

I didn’t even turn on my old PC I just started working within less than 15 min from my new MacBook connected to my Win10 VD via Receiver and i’ll just sort out what I need locally like Reflector, NAMP e.t.c over the weekend as its a busy week post our local partner event Citrix Partner Accelerator.

What Did I Do?
1. Unboxed my new Macbook
2. Plugged in the power and pushed the power button its been a while since I’ve heard that CHIME 🙂
3. Completed Apples on-boarding process including setting up iCloud including connecting to the Citrix employee Wi-Fi from our London, Paddington offices check it out at – https://twitter.com/CitrixUK/status/834742107055259650
4. Next I opened Safari and navigated to http://receiver.citrix.com and it auto detected for me that I am connecting from a Mac and presented me with a download link to Receiver for Mac 12.4.
5. Once downloaded I installed it simple!
6. Opened Citrix Receiver and i entered in my addr which then prompted me for my Citrix employee username, passwd and 2FA Token
7. BOOM Receiver synced all my virtual apps & desktops that I had previously selected on other device(s) within a few moments of signing in
8. I clicked on my Windows 10 Virtual Desktop powered by XenDesktop and my new mobile #SecureWorkspace is ready to go within less than 15 minutes!

What’s New
A full and complete list of what’s new is avaiable at – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/whats-new.html. I’ll start with one of my Citrix passions which is any and everything surrounding HDX technologies.

1. HDX Adaptive Transport is disabled by default in XAD 7.13* also referred to as EDT is a new HDX graphics mode that utilises both the UDP and TCP protocols with a fallback to TCP where UDP isn’t available. The HDX engineering team have engineered this new Citrix protocol called Enlightened Data Transport (EDT) which utilises the existing Citrix ports 1494 (ICA/HDX) and 2598 (Session Reliability) for both TCP and now new UDP so f/w ACL changes are near enough straight forward. To test this new graphics mode internally:

– Configure the ACL between your test end-point and through your internal network (over a VPN) VM running the 7.13 VDA to allow UDP and TCP for 1494, 2598
– Your test VM instance could be running in Azure (connected on-prem via a VPN) or on XenServer 7.1 and remember must be running the latest desktop or server VDA
– Your test end-point must be running the following min Citrix Receiver versions for Windows 4.7, Mac 12.4 and for iOS 7.2
– *In Studio create a machine catalogue, delivery group or use an existing one with your VDA upgraded from e.g 7.12 to 7.13 and then create a new HDX policy e.g HDX-TestofEDT and select the following HDX policy entitled “” and choose “Preferred“.

2. AMD Multiuser GPU (MxGPU e.g GPU Virtualization works with vSphere only) on the AMD FirePro S-series server cards for HDX 3D Pro workloads only e.g Desktop OSes ref – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/hdx/gpu-acceleration-desktop.html+ with support for up to 6 monitors, custom blanking & resolution, high frame rate and only GPU Pass-through is supported on the following hypervisors XenServer and Hyper-V. For further details please ref to the AMD website at – http://www.amd.com/en-us/solutions/professional/virtualization.

3. Intel Iris Pro (5-6th Gen Intel Xeon Processor E3) graphics processors supports H.264 h/w encoding for virtual apps & desktops, HDX 3D Pro support for up to 3x monitors (Ref to install options+), custom blanking & resolution, high frame rate. For further details and compatible Intel processors ref to – http://www.intel.com/content/www/us/en/servers/data-center-graphics.html

4. Other HDX enhancements include:

– Bidirectional content redirection – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/policies/reference/ica-policy-settings/bidirectional-content-redirection.html
– Wacom tablets improvements & connection methods – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/hdx/usb.html and also see http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/policies/reference/ica-policy-settings/usb-devices-policy-settings.html
– File copying performance enhancements for client drive mapping

5. StoreFront 3.9 support for the following below and for a closer look check out the following CTX blog article – https://www.citrix.com/blogs/2017/02/24/whats-new-in-storefront-3-9/

– HDX Adaptive Display
– CEIP automatic enrollment by default. To disable please ref to http://docs.citrix.com/en-us/storefront/3-9/install-standard.html#par_anchortitle_8ea6
– Importing of NUG configurations (ZIP file or via PowerShell) into StoreFront to setup through the XAD Wizard using the latest NetScaler UG 11.1.51.21+ ref – http://docs.citrix.com/en-us/storefront/3-9/integrate-with-netscaler-and-netscaler-gateway/import-netscaler-gateway.html to reduce and avoid misconfigurations.
– Not new but if you’re looking to security harden your StoreFront standalone or cluster ref to – http://docs.citrix.com/en-us/storefront/3-9/secure.html
– SAML auth through against your preferred Store with NetScaler Unified Gateway configured as your IdP – http://docs.citrix.com/en-us/storefront/3-9/configure-authentication-and-delegation/configure-authentication-service.html#par_anchortitle_d712

5. The Connection Quality Indicator is not part of the XAD 7.13 release but an invaluable Citrix tool for Citrix SysAdmins check out its capabilities at – https://www.citrix.com/blogs/2017/02/22/citrix-connection-is-slow-not-really/ and you can download it from – https://support.citrix.com/article/CTX220774 and it also inclues group policies for better SysAdmin controls to enable or disable the tool which is supported from XAD 7.6 LTSR and upwards ref the CTX220774 article. The below image is taken from a Window 10 virtual desktop powered by XenDesktop 7.x.

6. Linux Seamless published applications from a Linux supported OS using the 7.13 VDA – http://docs.citrix.com/en-us/linux-virtual-delivery-agent/7-13/whats-new.html and also please read the publishing apps for Linux at – http://docs.citrix.com/en-us/linux-virtual-delivery-agent/1-4/suse/configuring/publish-apps.html for advanced tips and guidance on seamless mode vs. window manger configuration.
7. LHC in 7.13 introduces a new support feature for brokering operations for Citrix Cloud when the internet connection between the Citrix Cloud Connector and the Citrix Cloud control plane at – https://citrix.cloud.com/ is in a failed state or unavailable due to an ISP outage. You can also force an outage following the documentation available at – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/manage-deployment/local-host-cache.html++ by creating and manually modifying the following registry entry “HKLM\Software\Citrix\DesktopServer\LHC with entry of OutageModeForced” set to the value in the documentation++ to force an outage for testing and or evaluation purposes prior to implmenting Local Host Cache. I’ve embedded below a simple architectural recap of LHC introdcued in XAD 7.12 and you can read in more depth detail about Local Host Cache from a previous blog post available at – http://axendatacentre.com/blog/2016/12/13/whats-new-in-xenapp-xendesktop-7-12/.

Finally LHC still provides support for brokering operations for traditional XAD Controller Site Database on-prem ref ++. I’d also recommend that you watch this TechTalks To Go covering LHC in XAD 7.12 release.

8. Provisioning Services 7.13 now supports Linux streaming and a brand new caching technique only available and supported on XenServer 7.1 called PVS-Accelerator. Check the following YouTube video from Citrix entitled “Introducing PVS-Accelerator, only available with XenServer!” via https://twitter.com/juancitrix/status/835202277317148672.

9. HDX Thinwire enhancements in 7.13 have resulted in up to 60% bandwidth savings. Take a look at the following CTX blog post at – https://www.citrix.com/blogs/2017/01/11/hdx-next-cuts-bandwidth-by-up-to-60-yes-sixty-percent/ which has some great high level LoginVSI 4.1.6 graphics comparing Thinwire in 7.12 vs. 7.13 on Windows Server 2012 R2 and 2016.
10. AppDNA what’s new ref – http://docs.citrix.com/en-us/dna/7-13/whats-new.html now includes support for Windows 10 Anniversary Update (AU) and now defaultor analysis and reporting, Secure Web reports and finally improved importing to process to analysis OSes and apps. There are a few more to be sure to check out the whats news!

Deploying XenApp 7.13 for Evaluation & Testing Purposes
The fastest way to deploy and test the latest new features from Citrix XA 7.13 release with little to no effort is to deploy the “Citrix XenApp 7.13 Trial” from Microsoft Azure available and accessiable at – https://azuremarketplace.microsoft.com/en-us/marketplace/apps/citrix.citrix-xa?tab=Overview.

Deploying & Understanding the NetScaler Gateway Service from Citrix Cloud

The following content is a brief and unofficial prerequisites guide to better understand NetScaler Gateway Service from Citrix Cloud test delivering virtual apps and desktops powered by XenApp & XenDesktop Service prior to deploying in a PoC, Pilot or Production environment by the author of this entry. The views, opinions and concepts expressed are those by the author of this entry only and do not necessarily conform to industry descriptions or best practises. The views expressed here are my own and do not necessarily reflect the views of Citrix.

Introduction & Overview
The NetScaler Gateway Service is a simple, clean. effortless and but most importantly a powerful way to demonstrate the power of Citrix Cloud by providing secure remote access to your HDX virtual apps and desktops from your resources location over the internet (https) securely. While this service is very very powerful & simple to implement and use, you should under the keep in-mind that NS VPX/MPX/SDX is fully featured vs. the NSG Service which is focused on delivery of HDX virtual apps & desktops! So in summary when implementing service undering what is right vs. relevant for the customer needs and requirements is very important. Finally you can read more about the service and its benefits at https://www.citrix.com/products/citrix-cloud/services.html.

+Enabling the NetScaler Gateway Service
1. Login to https://citrix.cloud.com
2. Select to Manage your XAD Service which will take you to https://xenapp.cloud.com/.
3. Select from the drop down menu “Service Delivery” which is beneath the top menu item displayed “Service Creation
4. Now Select to toggle “ON” and choose to use the NSG service (preferred for blog article only) or your own NetScaler (Unified) Gateway at your resource location and if you enable to the NSG Service you can choose to check the session reliability (2598) checkbox.

The UX
Users connect to https://.xendesktop.net and then login using there AD UPN domain credentials e.g lyndon-jon@x1co.eu and the user’s credentials are encrypted through-out the login process. User’s can equally choose between using a full Citrix Receiver (HDX Optimisation Pack 2.x.n for offloading Skype for Business 2015-2016) vs. HTML5 Receiver (HTML5 compliant internet browser) experience by selecting their username in the top right hand corner and selecting to “Change Receiver” to their preferred choice of Receiver. It also important to set the correct +HDX Policy to get the best UX that is good and balanced (backend vs. network vs. client connected device) so I’d suggest that you implement HDX Adaptive Display v2 by selecting the following policy entitled “Use video codec for compression” and select the following option “For actively changing regions” and thereafter tweak the frame rate and adjust the Thinwire color depth support as described at http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-12/whats-new.html#par_anchortitle_59c9 and you can also read more about benefits and a YouTUBE demostration on HDX Adaptive Display v2 at the following blog article I wrote in 2016 at – http://axendatacentre.com/blog/2016/10/01/foractivelychangingregions/.

HDX Traffic flow of the NSG Service
Please note that traffic flow is based upon the diagram avaiable at – http://docs.citrix.com/en-us/citrix-cloud/xenapp-and-xendesktop-service/netscaler-gateway-as-a-service.html as of Jan 2017.

1. User MUST login into cloud hosted StoreFront e.g https://.xendesktop.net. There credentials are securely handled please refer to – http://docs.citrix.com/en-us/citrix-cloud/xenapp-and-xendesktop-service/technical-security-overview.html to understand the traffic follow.
2. Once the user has authenticated successfully he/she can select to launch a virtual app or desktop.
3. User connects to the NSG Service powered by Citrix Cloud
4. Traffic is securely brokered to the Connector in your resource location that is severing up the user’s selected virtual app or desktop or both from the server or desktop VDA.

Tech Overview of the NSG Service
1. The Citrix Cloud NetScaler Cloud Gateway service on your Connector allows and provides the secure remote access feature of the NSG Service from your chosen resource location. I have written a blog article about the Connector services and leading best practises which you can read at – http://axendatacentre.com/blog/2017/01/27/understanding-the-citrix-cloud-its-services-architecture-connectors/.
2. To ensure high availability you should always deploy at a min a pair of Connectors within your resource location and increase the compute capacity of your Connectors as user demand increases initially and thereafter deploy another Connector based upon usage of service.
3. *To use the NSG Service you MUST configure to use the cloud-hosted StoreFront provided by Citrix Cloud under “Service Delivery” tab at https://xenapp.cloud.com/delivery.
4. The NSG Service only supports HDX Traffic only and the service is currently only available on Eastern, Western coasts within the USA and in Europe so for those users accessing virtual apps and desktops via the NSG Service outside of these geos or not in close proximity to an entry point will experience higher latency so tweak your HDX policy(s)+ accordingly or deploy a NS VPX in your resource location.
5. ICA files are STA signed the below example is a small snippet from my own PoC and testing*. I have also intentionally scrammed some of the unreliable text to :-).

Sample ICA file
My Azure vDesktop $S19-38]
Address=;40;CWSSTA;9D09CE5552BDE4581E888CD87EEEEFC

The NSG Service currently does not support and or is limited as of writing this blog article in Jan 2017 and based upon the embedded Twitter image – http://docs.citrix.com/en-us/citrix-cloud/xenapp-and-xendesktop-service/netscaler-gateway-as-a-service.html. Finally please remember that Citrix Cloud is consistently been updated and upgraded with new feature so please please refer to the online documentation and the service overview of Citrix Cloud even a day after posting the blog article as it may become out of date! You’ve been warned!

6. No support for Unified experiences (e.g Branding with your logo, colour scheme).
7. No support for Two Factor Authentication.
8. No support for authentication via outbound proxies for access outside of the resource location over the internet.

Suggested Top 10 for 2016
This is numbered 1 through 10 but in reality is in no particular order!

1. E-mail discovery for Citrix Receiver using DNS SRV records – http://docs.citrix.com/en-us/receiver/windows/4-3/receiver-windows-install-wrapper/receiver-windows-cfg-command-line-42.html internally and externally on the Gateway – http://docs.citrix.com/en-us/netscaler-gateway/10-1/ng-xa-xd-integration-edocs-landing/ng-clg-integration-wrapper-con/ng-clg-session-policies-overview-con/ng-clg-storefront-policies-con/ng-clg-storefront-email-discovery-tsk.html.
2. Implement SplitDNS or more technically correct “split-horizon DNS” – https://en.m.wikipedia.org/wiki/Split-horizon_DNS my favourite personally over email based discovery :-)!
3. Brand your NetScalers (Unified) Gateway – http://docs.citrix.com/en-us/netscaler-gateway/11-1/vpn-user-config/custom-portal.html and App Store (StoreFront) – http://docs.citrix.com/en-us/storefront/3-7/manage-citrix-receiver-for-web-site/unified-receiver-experience.html to match and keep it clear, clean and simple!

4. Implement HDX Adaptive Display v2 available in 7.11+ – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/policies/reference/ica-policy-settings/graphics-policy-settings.html as your default Graphics Mode and if you can’t then Thinwire Compatible Mode – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/hdx/thinwire.html.

5. If using Skype for Business 2015 or 2016 implement the HDX RealTime Optimisation Pack 2.x.n http://docs.citrix.com/en-us/hdx-optimization/2-1/hdx-realtime-optimization-pack-overview.html to offload the video/audio to the local end-points (Windows, Mac and Linux) saving on backend compute and density loss for XenApp.*

6. Implement domain pass-through for internal users – http://docs.citrix.com/en-us/storefront/3-7/plan/user-authentication.html.
7. Deploy the (latest) HTML5 Receiver for remote access – http://docs.citrix.com/en-us/receiver/html5/2-2/user-experience.html.

8. When using Citrix Receiver for Windows (with HDX engine 14.4), the GPU can be used for H.264 decoding wherever it is available at the client – http://docs.citrix.com/en-us/receiver/windows/4-5/improve.html.
9. Deploy Self-Service Password Reset (SSPR) – http://docs.citrix.com/en-us/self-service-password-reset/1-0.html.

10. The most difficult to justify probably re the cost(s) but assigning a low end vGPU GRID profile or utilising the Intel Iris Pro Graphics with XenServer 7 to provide enough/suitable GPU capacity to all virtual apps & desktops (oldISH and modern) provides a much better experience so setup a PoC to see and try if for yourself and finally NVidia now supports H.264 offloading onto there GRID Cards in 7.11 🙂 – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-new.html#par_anchortitle_59c9.

5. Enter in a name for your NS virtual appliance e.g ne1nug01 and select the VM disk type
5. Enter in a username and choose auth to be either SSH public key or Password I choose password to access the NS Admin WebUI for simplicity of all readers of this blog.
6. Select your chosen of default Subscription if you have more than one and then select your existing Resource Group where you XenApp 7.11+ environment and XenApp 7.11+ VDA Workers and your mgmt. VM running AD/DNS server resides. Remember I am keeping this simple as it’s intended for PoC’s only!
7. Continue to select your chosen Azure instance for NetScaler I choose DS2_V2 Standard which consists of 2 Cores, 7GB of RAM.
8. Select your storage account, virtual network & subnet e.t.c and high availability set then click Select to continue.
9. Review your purchase of NetScaler and then click Ok to purchase and Azure will begin building your NetScaler VPX in your Azure chosen subscription which will take no more typically than 10 minutes.

Setting up & Licensing your NetScaler on Azure
Firstly be aware that when deploying a NetScaler instance on Azure for virtual apps & desktops you’ll be setting up NetScaler to run in single IP mode (YES!) which means that you’re connecting to internal TRU resources on the NetScalers IP addr (NSIP) but you connect using different ports e.g ICA Proxy on 8443 so lets begin with the setup.

1. Login into your NetScaler using the NS Admin Web UI do not provide a SubnetIP Addr (SNIP) just select Do It Later and proceed with the initial setup as per normal.
2. Now that you have setup your NetScaler you need to license it so remain logged into and open a new tab in your browser of choice and Google “Citrix Eval Store” or save this link – http://store.citrix.com/store/citrix/en_US/cat/ThemeID.33753000/categoryID.63401700
3. Select under Networking -> NetScaler ADC
4. Next select the following model “VPX” select variation e.g “Platinum 1000” select duration e.g “90 Days”.
5. Complete the onscreen process note that you will require a .Citrix.com account or you need to create an account.
6. Once you receive an e-mail with your key/code head over to at https://www.citrix.com/account/toolbox/manage-licenses/allocate.html or goto and select find and allocate your licenses or look for the licensing button (link) and select it.
7. If your key/code it not visible select “Don’t see your product?” in text in/around the top right-hand side. A pop-up appears now enter in the code provided on e-mail from the Citrix Eval Store e.g “CTX34-XXXXX-XXXXX-XXXXX-XXXXX” and continue.
8. You will need to enter in the Host Id of your NetScaler it can be found once logged in using the NS Admin Web UI “NetScaler -> System -> System Information” then look under the heading “Hardware Information” and you find “Host Id” copy and paste it into the required field and then download the license file.
9. In the NS Admin Web UI click the cog icon top right then select licensing and upload the license and select to reboot the NS to apply the license.
10. Log back in and enable the features that you require e.g right click on the “NetScaler Gateway” and select “enable” e.t.c

Setup Type Choice 8443 Default without an Azure L/B for XenApp using the XenApp/XenDesktop Wizard
Now that you have setup NetScaler within your Azure subscription in your chosen region you’re ready to begin setting up NetScaler to front virtual apps & desktops (Server OS 2012 R2 or 2016) powered by XenApp 7.11+.

Sample Text Based Diagram

User Azure NetScaler StoreFront XenApp
https://FQDN:8443/ Accepts requests from Azure to NSIP on https://8443 (Single IP Mode) Accepts requests on the Gateway & Call-back FQDN on https://FQDN:8443 Accepts & launches user’s virtual app(s) & desktop(s) as requested

1. Login to your NetScaler VPX click “Settings -> Licensing” now check that License type is Platinum and Model ID 1000
2. Select the XenApp/XenDesktop wizard and review the prerequisites carefully prior to continuing BUT in summary you’ll need an SSL Cert, LDAP service account + details, XenApp 7.11+ environment with StoreFront.
3. Enter in the static IP addr assigned by Azure or OTHER METHOD of your NetScaler VPX YES that’s right!
4. IMPORTANT STEP: Change the default port of 443 to 8443 on the Gateway IP addr
5. Set Up the rest of the XAD wizard as normal
6. IMPORTANT STEP: Setup StoreFront to allow remote access however the configured default gateway and Call-back FQDN addresses MUST include 8443 e.g https://go.x1co.eu:8443 instead of just https://go.x1co.eu
7. Setup external DNS entries e.g go.x1co.eu to point to your NetScalers static IP addr found in the Azure ARM Web UI and once you have verified it is functioning correctly using a shell (IPCONFIG /FLUSH after settin-up the DNS entries waiting 10-15 min depednant upon your ISP) the open up an internet browser and type in e.g https://go.x1co.eu:8443 and dont forget the :8443 at the end of the FQDN.
8. Attempt to login either using sAMAccountName e.g username or userPrincipalname e.g username@x1co.eu and then you should be able to successfully login and launch your virtual apps & desktop as per the below image.

Setup Type 443 for XenApp using an Azure Load-Balancer & the NetScaler XenApp/XenDesktop Wizard

Sample Text Based Diagram

User Azure Azure Load-Balancer NetScaler StoreFront XenApp
https://FQDN/ https received request and forwarded to NetScaler on https://FQDN:8443

Accepts requests from Azure L/B on https://FQDN fwd to NSIP on https://8443 (Single IP Mode) Accepts requests on the Gateway from HTTPS://FQDN but the Call-back FQDN is on https://FQDN:8443 Accepts & launches user’s virtual app(s) & desktop(s) as requested
https://FQDN ↔ AzureL/B ↔ NetScaler:8443 NetScaler https://FQDN:8443 ↔https://FQDN StoreFront StoreFront Call-back https://FQDN:8443
StoreFront configured NetScaler Gateway https://FQDN

1. If you are choosing this option as your preferred lets hope then complete steps 1-5 and also step 7 to save you time!
2. IMPORTANT STEP: Setup StoreFront to allow remote access however the configured default gateway MUST BE e.g https://go.x1co.eu NOTICE NO :8433 YES not :8443 here. Now on the call-back FQDN addresses YOU MUST include 8443 e.g https://go.x1co.eu:8443 instead of just https://go.x1co.eu otherwise fronting NS with an Azure L/B to acheive HTTPS://FQDN for the XAD Gateway (ICA Proxy) will NOT WORK!!!!
3. Now switch to the Azure ARM Web UI. You should probably read the following useful resources – https://azure.microsoft.com/en-gb/documentation/articles/load-balancer-overview/ and for PowerShell creation check out – https://azure.microsoft.com/en-gb/documentation/articles/load-balancer-get-started-internet-arm-ps/ for any Citrix consultants out there.
4. Azure Load-balancer and click on the “+” at the top and provide a “Name” and for the type choose “Pubic” and select your Azure “Subscription” “Existing Resource Group” and its location (Same as NetScaler deployed instance) then click “Create”
5. Now it will list the available public IP addr just select the “+”
6. Enter in a name and choose your assignment choice “Dynamic” vs. “Static” and click OK.
7. Azure will then provision your Azure L/B (Wait….Maybe coffee or tea break?)
8. Once created select your Azure L/B
9. Select “Backend Pools” enter in a name then choose your availability set and then your VM’s or VM e.g NetScaler. Azure will then provision your Azure L/B with a backend pool (Wait….)
10. Select “Frontend IP Pool” click “+” enter in a name then choose your IP addr e.g NetScaler VM and then enter in a name (all names should differ makes identification easier so a good naming convention helps 🙂 now) and choose your assignment choice “Dynamic” vs. “Static” and click OK (Updating….)
11. IMPORTANT STEP: Select “Inbound NAT Rules” select the resource from your Frontend IP Pool list from the previous point (10). Select the service “HTTPS” and port to be 443 then select the target “NetScaler VM” and then vErY iMpOrtAnt select under “Port Mapping -> Custom” and in the “Target Port enter in 8443” and click save. (Wait…)
12: Now navigate to https://FQDN and attempt to login either using either sAMAccountName e.g username or userPrincipalname e.g username@x1co.eu and thereafter you should be able to successfully launch your virtual apps & desktop published by XenApp 7.11+. The below image represents the end goal when fronting an Azure NetScaler in Single IP Mode with an Azure Load-Balancer as per the below image.

Video Citrix Workspace Cloud: How It Works

PoC Introduction & Overview (This is a Public Draft Blog Article & May Contain Some Errors)
In this particular instance I will be deploying a Citrix Workspace Cloud (CWC) PoC using the Apps & Desktop service which is Citrix online service and is essentially made up of five compoments in my personal view these are people (Users, Consultants & SysAdmins), the Control Plane which is hosted by Citrix and is high available and accessible at – https://workspace.cloud.com/, Resource Locations which could be private, public (IaaS) or hybrid clouds which host and run your actual CItrix workloads e.g servers or desktops OSes with the VDA’s installed and optionally StoreFront and or NetScaler Unified Gateway, Receiver for access to your published virtual apps & desktops and finally the CWC connector which makes everything just work safe & securely.

Please note that I will update this blog post with a how-to re deploying NS for remote access from AWS EC2.

Datasheet for Citrix Workspace Cloud
https://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/explore-workspace-cloud-take-a-test-drive-or-trial.pdf

What you need
For this PoC I may refer to AWS and XenServer concepts as my home lab is deployed in a Hybrid Cloud model e.g some of my Citrix workloads are in hosted in AWS EC2 (N.Virgina) while others are running on a XenServer 6.5 SP1+ host at my house in London. You don’t have to use AWS like I am for your PoC you could use any IaaS provider e.g Azure, Rackspace, Peer1 or even on-prem with your own host(s) running XenServer, Hyper-V and of course vSphere :-).

1 – CWC trial account entitling you to the CWC Apps & Desktop Service and Identity & Access Management e.g for adding users from your domain and to download the CWC Connector.
2 – Your resource location of choice mine is AWS from here on in through-out this blog article.
3 – 1x Windows Server 2012 R2 I’ll call this VM WDC01 running AD, DNS at a minimum and the Citrix Receiver (http://receiver.citrix.com), CWC Connector downloaded on the desktop (explained later).
4 – 1x Windows Server 2012 R2 domain joined and I’ll call this VM CXA01 with the latest XA 7.8+ Server VDA (https://www.citrix.com/downloads.html which requires a valid Citrix.com customer/partner account with access details ) downloaded.
5 – AWS security groups (on-prem f/w ACL) to allow outbound traffic on TCP 443 (HTTPS) to the Internet, allow HTTPS/ICA/HDX/RDS traffic including HDX RealTime ports for audio and video between all VM’s within your chosen network.
6 – Some suggested test application examples could be Microsoft’s Office 2016 or OpenOffice, Notepad ++, The Gimp, Autodesk Viewer. WaRnInG!!! Disclaimer – Please refer to the ISV’s EULA for terms of usage prior to downloading, installing, configuring and publishing virtual apps to test and play with!.
7 – *Create friendly DNS entries to be used later for WDC01 e.g DNS entry of cwccontroller.axendatacentre.com or your could stick with host name.domainname format it’s your choice. Note: Be sure to setup and configure not just fwd. but also reverse DNS within resolution/look-up!

Setting up your Resource Location
1 – Login as the Domain Admin on WDC01 and navigate to https://workspace.cloud.com and sign in with your trial access details provided by Citrix.
2 – Select from the list on the very TOP left-hand corner Identity & Access Management next click the plus/+ sign and follow the onscreen prompts to download the CWC Connector/agent.
3 – Before installing the CWC Connector/Agent please be sure to read the following documenation – http://docs.citrix.com/en-us/workspace-cloud/workspace-cloud/what-is-a-workspace-cloud-connector-/workspace-cloud-connector-technical-details.html. Once downloaded double click on the CWC Connector/agent and when prompted enter in your CWC trial access details and the installation will complete successfully if the access details provided are correct and if 443 HTTPS is enable outbound to the Internet from WDC01 to https://workspace.cloud.com.
4 – Take a short 1-3 min comfort break then refresh your web page for https://workspace.cloud.com and navigate back to Identity & Access Management and you should see your domain appear within the list, then you may proceed. If you don’t check your firewall ACL’s locally on the Windows server or virtual f/w at the edge of your VPC network and also check your AWS Security Groups are setup correctly to allow in/outbound access on HTTPS/443.

Note: If you turn off WDC01 you’ll receive and error at this page and manage & monitor tabs within the Apps & Desktop Service are NOT accessible until access is restored! Likewise if you only have 1x CWC Connector/agent then you may see an amber warning under domain within Identity & Access Management as you only have 1x CWC Connector/agent and it suggested even for a PoC to install 2x instead of 1x.

5 – Login as a Domain Admin on CXA01 and mount the XA 7.8+ VDA media by right clicking and left clicking on Mount then navigate to Windows Explorer and double click on D drive that has recently mounted with the XA 7.8 installation media and then proceed to select to install the Server VDA from the splash screen or if your downloaded the Server VDA *.exe (suggested & recommended) from Citrix.com then double click to install the VDA. In each case you’ll require 2x reboots as per normal like on-prem installations however now on CXA01 there is one exception at the controller step type in cwccontroller.axendatacente.com* or the hostname.domainname for WDC01 (Point to the CWC Connector/agent that you previously installed) and then continue with installation and once the installation is completed on CXA01, then verify that the VDA has registered and is communicating with WDC01 e.g cwccontroller.axendatacentre.com by reviewing CWC service or the event logs within Computer Management. Tip: Install to enabling remote connections initially to get your head around how the CWC Apps & Desktop Service actually works.
6 – You’ve now successfully completed setting up your XenApp worker for your chosen resource location in my case it’s an AWS EC2 located out of N.Virginia. If your curious about the CWC connector there is a tech overview avaiable at – http://docs.citrix.com/en-us/workspace-cloud/workspace-cloud/what-is-a-workspace-cloud-connector-/workspace-cloud-connector-technical-details.html be sure to review it.
7 – Now we need to continue with creating a machine catalog, delivery group in the hosted Studio and obviously publishing your virtual apps & desktop (server based).

Create a Machine Catalogue and Delivery Groups to publish Virtual apps & desktops
1 – Now go back to the homepage at https://workspace.cloud.com and to the right of the Apps & Desktop Service click “Manage” to launch the management interface which provides you with an Overview page (Scroll to the bottom to find out your cloud hosted StoreFront address. Tip: If you get an red bar with an error message check that your CWC Connector/agent at your resource location is up and available and showing as green for your domain at the Identity & Access Management tab!.
2 – Scroll to bottom of the overview web page to find out exactly what your cloud hosted StoreFront addr is. It should follow the following format https://{TENANT NAME}.xendesktop.net/Citrix/StoreWeb/. Right click on it to open a new tab and to remain at https://apps.cloud.com/. You should be able to login using your test AD security group. Tip: You won’t see any published virtual apps or desktops currently as you have not created a machine catalogue or delivery group.
3 – Go back to the Manage Apps & Desktops Service web page and click Manage or Monitor this will embed a custom, hardened published app version of Studio or Director using the HTML5 Receiver so please ensure that you are utilising an HTML5 compliant internet browser that supports the HTML5 Receiver.
4 – Assuming you’ve clicked on Manage firstly navigate to Hosting Connections create a connection to your chosen resource location either on-prem or cloud (Private or Public) details for setting up hosting connections are available at – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-8/manage-deployment/connections.html. Once setup wait 1-2 min before proceeding you don’t have to by the way! I do.
5 – Click Machine Catalogue and create as per normal for detailed on how-to please refer to – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-8/install-configure/machine-catalogs-create.html. Tip: I’d suggest as its your first time using the CWC Apps and Desktop service create your machine catalogue with a single VM with the VDA installed to allow remote connections as described earlier to allow you to get around how the CWC Apps and Desktops Service actually works. You don’t have to either it’s your choice.
6 – Click Delivery Groups and create as per normal aswell and please refer to – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-8/install-configure/delivery-groups-create.html for guidance delivering virtual apps (Skype for Business 2015 also implment the HDX Optimisation Pack 2.0 check out – https://www.citrix.com/blogs/2016/01/12/citrix-and-microsoft-unveil-v2-solution-for-skype-for-business/ for more information) & desktops (Windows Server 2012 R2). TIP: The name you provide your Delivery Group filters through to the Workspaces at – https://workspace.cloud.com/workspaces and becomes the default name of your published virtual & desktops services that you will assign to your subscribers (users) workspace.
7 – You’ve now successfully setup a Machine Catalog and Delivery Group using the CWC Apps & Desktop Service to published a virtual apps & desktop, however prior to accessing your virtual apps & desktops you’ll need to create a Workspace and add subscribers (users) including which published resources your subscribers (users) are able to access otherwise they wont be able to login nor access any published resources.

You should have the Server VDA and CWC Connector now installed see the below example image below.

Create a Workspace to Delivery published virtual apps & desktops
1 – A workspace consists of a collection of services from CWC e.g Secure Documents (ShareFile), Apps & Desktop Service (XenApp/XenDesktop) and so forth that SysAdmins can combine together to form e.g a Pre-Sales workspace that may consist of a virtual apps e.g Skype for Business 2015 that is also offloaded with the HDX Optimisation Pack 2.0 – https://docs.citrix.com/en-us/hdx-optimization/2-0/hdx-realtime-optimization-pack-about.html and a virtual desktop e.g a dedicated Windows 10 or 2012 R2 desktop. A workspace also consists of subscribers (users) who access the workspace which contains published resources created by Citrix SysAdmins. Please ref to http://docs.citrix.com/en-us/workspace-cloud/workspace-cloud/get-started/creating-and-publishing-a-workspace.html which explains how-to create a workspace, define subscribers and published resources.
2 – Once you have created a Workspace and assigned subscribers, resources then users can login at https://{TENANT}.xendesktop.net/Citrix/StoreWeb/ from there resource location and gain access to there virtual apps & desktops.
3 – Managing your newly created Workspace is easy following this useful online document from eDocs – http://docs.citrix.com/en-us/workspace-cloud/workspace-cloud/get-started/manage-a-workspace.html.

Example of my virtual desktop (Server based) delivered by CWC using the XenApp 7.8 VDA. I also use the same theme for my complete XenApp 7.8 deployment in AWS yes I have both deployed and configured 🙂

A first for me
This is the first time I’ve written a blog post (primarily) completed in the air traveling from somewhere between London – England, Oslo – Norway and Stockholm – Sweden.

Disclaimer
This blog article should be considered to be a draft still and therefore may contain errors and I will be updating and adjusting it time permitting and adding in how-to front this CWC Apps & Desktop service deployment in my AWS EC2 resource location with NetScaler Unified Gateway – https://www.youtube.com/watch?v=qT739UoR8d0.

Preview of HDX 3D Pro with a Linux VDA
Please note that the following YouTUBE video represents a preview only of HDX 3D Pro with the Citrix Linux VDA.

An Introduction & Overview
Citrix released the Linux VDA 1.0 which enables and allows for the safe, secure delivery of Linux based virtual desktops that are controlled by Citrix Studio however VM provisioning and on-going image management is maintained by traditional Linux tools these include but are by no means limited to Puppet or Chef.

Currently only the SuSE Linux and Redhat Enterprise Linux distro’s are supported however numerous Citrix professionals around the global have successfully setup and delivered a Linux VD utilise CentOS following the steps based in the “Installation Guide for Red Hat Enterprise Linux Version 1.1” which is available at – http://docs.citrix.com/content/dam/docs/en-us/xenapp-xendesktop/xenapp-xendesktop-7-6/downloads/Linux%20Virtual%20Desktop%20Installation%20Guide%20for%20Redhat%20Enterprise%20Linux.pdf or for CentOS focused approach check out – https://www.citrix.com/blogs/2015/08/25/installing-the-linux-vda-on-red-hat-or-centos-6/ written by Adrian Taylor – https://www.citrix.com/blogs/author/adriant2/.

As this is my first time writing about Citrix’s Linux support its worth noting and mentioning that Citrix provided a tech preview (TP) ref – https://www.citrix.com/news/announcements/aug-2014/citrix-offers-technology-preview-of-linux-virtual-apps-and-deskt.html prior to the official GA launch of the Linux VDA 1.0 which in my view received very positive feedback and comments in particular from with the UK/Ire Citrix partner community.

What’s New
1. Obviously my fav is “Support for Thinwire Compatible Mode” 🙂
2. The Linux VDA supports dual monitor out-of-the box with maximum resolution of 2560×1600 per monitor and can be configured to support up to 9 monitors.
3. Improved Active Directory and Centrify support*
4. Further extended OS support for Redhat and SuSE Linux enterprise editions. Please read the following for CTX blog article re support issues for other Linux OS disto’s at – https://www.citrix.com/blogs/2015/10/16/supporting-linux-distributions.
5. Linux XDPing which is available at –
http://support.citrix.com/article/CTX202015.
6. Support for Linux Dedicated VDI Desktops which in the initial Linux VDA 1.0 released targeted a hosted shared VD approach as Linux is a multi-user OS.
7: * For a comprehensive overview of all the features in the Linux VDA 1.1 please check out – https://www.citrix.com/blogs/2015/10/23/whats-new-in-linux-virtual-desktop-v1-1/.

Use Case(s)
Its essentially about providing customers with the choice and flexibility to delivery either a VD that is based upon Windows OS with Microsoft Office 20xn, 3rd party apps OR a supported Linux OS with OpenOffice/Libra Office, 3rd party apps.

Pre-requisites & System Requirements for Deploying the Linux VDA 1.1 (Draft + The Basic’s Only)
1: Download one or both Linux VDA’s for there Redhat or SuSE along with the script which is available at the Linux VDA download area – http://www.citrix.com/downloads/xenapp/components/linux-virtual-desktop-11.html.
2: The following Citrix Receivers are currently supported: Windows Receiver version v4.2+, Linux Receiver version v13.0+, Mac OSX Receiver v12+, Android Receiver v3.4+, iOS Receiver 5.9.4+, HTML5 Receiver 1.6 (via Access Gateway).

Deployment Preparation Overview (DRAFT & MAY CONTAIN ERROR(S))
0. The section also contain the pre-requite, system requirements for each virtual appliance (V/A) for NetScaler and the XenMobile Server (XMS).
1. Review the XenMobile comparability matrix at – http://docs.citrix.com/en-us/xenmobile/10-1/xmob-system-requirements/xmob-10-understand-compatibilitymatrix-con.html to choose the correct NS build vs. XMS build.
2. Download the V/A’s for each at signing in with your Citrix partner access details.
3. You need an SSL certificate a wildcard is recommend for simplicity and this should be using at min a 2048-bit key for your CSR that you submit to your CA. If you are experiencing the following issue enrolment issue Profile Installation Failed “The server certificate for ‘https://’ is invalid“ the please review http://axendatacentre.com/blog/2015/03/29/xenmobile-10-0-poc-considerations/ to help resolve this issue.
4. Generate an APNS certificate following this process at http://docs.citrix.com/en-us/xenmobile/9/xmob-dm-config-requesting-apns-con.html and sign your APNS certificate with Citrix at – https://xenmobiletools.citrix.com/.
5. You need to be aware that the port communication between the different components has changed and also the placement of the XMS V/A in XenMobile 10. A network diagram can be viewed at – http://docs.citrix.com/en-us/xenmobile/10-1/xmob-arch-overview-con.html I would recommended that you please refer to the figure 4. MDM and MAM modes and also figure 5. Cluster deployments.
6. XenMobile 10 today as of writing this blog post requires the following FQDN and IP ADDR reservations to be made available when fronting a XMS V/A with NS appliance either virtual or physical 10.5.x.n and 11.x.n. Please note that for simplicity I will refer to a NetScaler Virtual Appliance V/A from here on in.

7. NetScaler today as of writing this blog article requires the following IP ADDR reservations for NetScaler to allow you to front Citrix e.g “XenMobile”, ShareFile e.t.c and none-Citrix workloads e.g web services, exchange servers, application servers and much more.

– 1x DMZ private static NetScaler IP addr
– 1x DMZ private static NetScaler Mgmt IP addr for mgmt. of your NS virtual or physical appliance
– 1x DMZ private static Subnet IP addr for the NetScaler to access resources within your TRU network

8. Once you have successfully deployed your XMS use the built-in 30 day licenses for the initial configuration then allocate some eval licenses against the XMS hostname. You can allocate XM 10 licenses by choosing the “MDM/Enterprise 99 User” from – http://store.citrix.com/store/citrix/en_US/pd/productID.306222300/ThemeID.33753000. Once you have licensed the XMS V/A then proceed to successfully deploy the NS V/A and login into the NS V/A mgmt. interface which will be the NS’s mgmt IP addr find the HostID or utilise the following CTX article entitled “How to Allocate NetScaler VPX Licenses” – http://support.citrix.com/article/CTX133147 which will be required to license your NS V/A. Once you have the HostID visiting the Citrix Evaluation Store at – http://store.citrix.com/store/citrix/en_US/cat/ThemeID.33753000/categoryID.63401700 and allocate as an eXaMpLe a 3000 VPX at platinum for 90 days at – http://store.citrix.com/store/citrix/en_US/pd/productID.278306700/ThemeID.33753000 and also allocate a “Universal 99 Concurrent User Connection” from – http://store.citrix.com/store/citrix/en_US/pd/productID.282559700/ThemeID.33753000 once again for 90 days.
9. Reboot both the NS, XMS V/A and validate that they are back up and running and functioning as expected using the CLI and or the Admin WebUI’s of each V/A.

Let’s Deploy XMS fronted by a NS (DRAFT & MAY CONTAIN ERROR(S))
1. Login into NS Admin WebUI and navigate to the licensing tab and validate that you have all green ticks and ensure that you have 99-104 Universal licenses if not please read step 8 above before proceeding.
2. In the bottom left-hand corner click on “XenMobile” and select “XenMobile 10” from the dropdown list on the XenMobile initial wizard welcome page.
3. Under the NetScaler for XenMobile section to the left-hand side select the following “Access through NetScaler Gateway” (MAM e.g Worx’s Apps) and “Load Balance XenMobile Servers” (MDM) and then click on Continue.
4. Enter in the IP addr e and leave the port as 443 and provide a Virtual Server Name then click Continue.
5. Select and existing wildcard card certificate or upload a new wildcard certificate then click Continue.
6. Select and existing LDAP binding or create a new LDAP binding and then click Continue. Example of a Base DN for the domain axendc.co.za with domain users residing with the default Users folder within AD would e.f “Cn=Users,dc=axenc,dc=co,dc=za“.
7. Under Load-Balancing FQDN for MAM enter in a for the FQDN and for the IP addr beneath is enter in IP addr f and then click Continue. Please leave the defaults as is for now BUT please be aware that we will are not be performing any SSL Offloading, split tunnelling.
8. Select the same SSL cert as per step 5 above unless its NOT a wild card certificate in-which case then please upload the SSL cert for the MDM FQDN before proceeding. Click Continue.
9. Click “Add Server” under the XenMobile Servers section and enter in IP addr h and the click Continue. Note: Port for communication is 8443!
10. Click “Load Balance Device Manager/XenMobile Servers“.
11. Enter in the IP addr g and alter or leave the default name of the Virtual Server and click Continue. Note: Communication is HTTPS or SSL_Bridge as we choose not to perform HTTP or SSL Offloading in step 7 above.
12. You’ll notice that your XenMobile Servers IP addr’s are already automatically inserted under the XenMobile Servers section click Continue. Note: The Ports for communication are 443, 8443!
13. Click Done!
14. You have now successfully deployed a single XMS V/A fronted by a NS V/A. Once the wizard has completed you can click Edit under the “NetScaler Gateway” section on the top right-hand side under the Test Connectivity button to back into the wizard and modify the split tunnelling options to meet your organisations needs and or requirements.

XenMobile 10.0

The following content is a brief and unofficial prerequisites guide to setup, configure and test XenMobile 10.0 prior to deploying in a PoC, Pilot or Production environment by the author of this entry. The views, opinions and concepts expressed are those by the author of this entry only and do not necessary conform to industry descriptions or best practises.

Shortened Names
XENMOBILE – xm
XENMOBILE SERVER – xms
VIRTUAL APPLIANCE – v/a
FEDERAL INFORMATION PROCESSING STANDARDs – fips
NETSCALER GATEWAY – nsg
VIRTUAL IP ADDRESS – vip
MOBILE APPLICATION MANAGEMENT – mam
MOBILE DEVICE MANAGEMENT -mdm

What’s New
1: XenMobile is now a single unified hardened Linux virtual appliance.
2: Complete overhaul of the Web UI which dramatically simplifies policy setup & configuration of MDM + MAM policies and it allows for the management of multiple platforms within a single policy.
3: Built-in V6 Citrix Licensing server provides a 30 day trial/evaluation and also support for remote V6 CTX licensing server.
4: Built-in PostgreSQL database recommended for PoC’s and there’s also support for remote MS SQL database which is recommended for production deployments.
4: XMS V/A includes IPtables which is a Linux firewall – http://en.wikipedia.org/wiki/Iptables.
5: XMS placement is in the DMZ. The V/A is hardened and is FIPS 140-2 compliant and remember you data is actually stored in a MS SQL database unless your utilising PostgreSQL database within the XMS V/A.
6: Traffic flow and ports between NetScaler Gateway and the XenMobile Server (XMS) have changed please refer to eDocs for an architecture overview of the changes at – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-arch-overview-con.html.
7: The Admin Web UI is now on https://XMS-FQDN:4443/. This port is not configured as part of the XenMobile 10 wizard on NetScaler Gateway build 10.5-55.8 which means that you will not be able to access the mgmt. Admin Web UI from the internet it will only be accessible from the DMZ and the TRU network dependant upon your firewall(s) ACL list.
8: New WorxHome build 10.0.3.83 which is also backwards compatible from XenMobile 10.x.n
9: The XenMobile NetScaler Connector (XNC) currently is still a separate Windows Server.
9: You can find our more by watching the following Mobility Master Class: What’s New in XenMobile 10 available from Citrix TV.

Deploying XenMobile 10
1: Review the system requirements for XMS at – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-system-requirements.html to understand the supported hypervisors, computing requirements. You should also make sure that you review the latest XM architecture as it has changed between XenMobile 9.0 vs. 10.0 and it can be viewed at – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-arch-overview-con.html. You’ll notice that the traffic between NSG and the XMS V/A has changed however all traffic externally still occurs on there traditional ports (443, 8443, 2195, 2196, 5223).
2: Review and understand the NetScaler Gateway compatible requirements at – http://support.citrix.com/proddocs/topic/worx-mobile-apps/xmob-10-understand-compatibilitymatrix-con.html.
3: Make sure that you print out and fill-in all the pre-requitses for the XMS V/A ref – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-xenmobile-install-checklist.html prior to deploying your XMS V/A on your chosen hypervisor.
4: Once you have uploaded the V/A to the hypervisor and booted it complete the onscreen instructions ref – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-install.html. Once you are finished login into the Admin WebUI replacing the IP Addr with your XMS V/A ip addr from this example https://XMS-IPADDR:4443/ and login with Administrator account your specified during the deployment and NOT admin which is used to access the XMS V/A CLI from your hypervisor only.
5: Once you’ve logged in you’ll need to have the following listed below available to successfully complete the second part of the initial XenMobile 10 deployment. There is also a pre-requites check list available at – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-xenmobile-install-checklist.html.

– Citrix v6 licensing file for either local or remote. Remote is recommended for H/A purposes.*
– Microsoft Active Directory (AD) ip addr or FQDN, base DN, domain, search service account with read-only permissions.
– Certificate in *.p12 or *.pfx format for the SSL_Listener which is used for two way secure HTTPS communication to the XMS V/A.
– APNS certificate.
– Separate MDM and MAM+ FQDN’s correctly setup in DNS with fwd and reserve lookup’s configured and each configured with its own static IP addr for external resolution.
– 3x VIP for configuring XenMobile 10 with NetScaler Gateway 10.5.55.8 +. You can find a compatible NSG V/A version and builds at – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-10-understand-compatibilitymatrix-con.html.
– MS SQL Database server configured to accept traffic and with write/read privileges to create and manage the remote XMS database.
– Mail server configuration which enables and provides workflow email messages, notifications to users e.t.c

6: Follow the onscreen prompts and once completed the web UI deployment wizard then you have successfully deployed a XMS V/A. Please not reboot the XMS V/A so that the existing SSL certificates for HTTPS can be unbound and the newly uploaded SSL cert(s) can be bound to HTTPS.
7: You may now setup a XMS cluster and configure H/A with a NSG and thereafter begin configuring your XenMobile 10.0 environment. See the H/A section for a how-to.
8: Logon to one of the XMS v/a direct IP addr e.g https://XMS:4443/ if in H/A fronted by the NSG as the XenMobile 10 wizard will not configure 4443 which means that you cannot access the mgmt interface via the VIP owned by the NSG. This means that the mgmt interface is not accessible either internally or externally on the FQDN that resolves the VIP owned by the NSG.
9: Scaling XenMobile 10.0 from 1000 up to 100,000 devices – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-scaling-xm.html.

XMS V/A High-Availability (H/A)
1: Prior to understanding how-to setup a XMS H/A or clustering you need to understand that the minimum requirements are for a remote CTX v6 licensing server and MS SQL database as the XMS V/A do not hold any user/cfg information this is all held in the remote database.
2: Once your have setup XMS follow the prompts in the CLI to enable clustering and configure the IPtables firewall ACL and then finally shut it down and clone it.
3: Rename the cloned XMS V/S to your required naming convention and then boot up the cloned XMS V/A login to the CLI and changed the IP addr and ensure that the IPtables firewall ACL ports are correctly enabled then shutdown the V/A.
4: Boot the first XMS V/A and then 60 seconds later boot the cloned XMS V/A and login to the CLI to very the cluster is enabled and then login into the XMS admin WebUI to verify that the cluster is up and functioning as expected. The original XMS V/A will be the oldest in the cluster.
5: You can now proceed to setting up the load-balancing for the XMS V/A’s with NSG to service MDM + MAM requests.

Supported NetScaler Gateway (Builds & Versions) for XM 10
1: 10.5.55.8 MR5; 10.5.54.9 MR4; 10.5.53.9 MR3; 10.1.130 MR & 10.1.129 MR ref – http://support.citrix.com/proddocs/topic/worx-mobile-apps/xmob-10-understand-compatibilitymatrix-con.html.

Deploying XM 10 with NetScaler Gateway 10.5.x.n (Draft)
1: Before beginning its worth mentioning that the way I will be describing how-to deploy XenMobile 10 in this blog article will be to utilise to external static IP addr’s + FQDN’s that are NATed to DMZ IP addr’s and I will utilising SplitDNS for device mgmt. in/outside of my TRU network. I will also be implementing the described XenMobile 10 environment below utilising an SSL Bridge although offloading includes a few more minor steps the intention of this section is aimed at helping you front your XenMobile 10.0 deployment with a NSG 10.5.x.n V/A.
2: Please review the following CTX article entitled “FAQ: XenMobile 10 and NetScaler 10.5 Integration” – http://support.citrix.com/article/CTX200430 which will aid you in been able to setup and configure load-balancing for XMS V/A’s, mVPN for Worx’s apps for XenMobile 10 with NetScaler Gateway 10.5.x.n.
3: You’ll require the following prior to be beginning:

– Correct NetScaler (Gateway) build +_ version the NSG version + build I’ll be discussing here is NetScaler Gateway 10.5.55.8 MR5 but you can check the latest supported version + builds at – http://support.citrix.com/proddocs/topic/worx-mobile-apps/xmob-10-understand-compatibilitymatrix-con.html
– 1x FQDN for MDM e.g. mdm.axendatacentre.com * that resolves to both external internet routable static IP addr and your internal assigned static IP. Please note that this should match exactly the FQDN entered in at the time of the deployment of your XMS V/A during the first phase in the CLI the text your looking for is/was “XenMobile Server FQDN:” and its highlighted in yellow. It is also worth/noting that if you have utilised an internal domain e.g xms.abc.local as the FQDN this will only manage devices internally as that FQDN is not routable on the internet so you’ll only be able to manage devices INSIDE of the trusted network to its recommended to a FQDN that is internet routable and you can utilise SplitDNS to manage traffic requests to the NSG VIP’s for XenMobile.
– 1x FQDN for MAM (Worx’s Apps) e.g. mobileapps.axendatacentre.com * that resolves to both external internet routable static IP addr and your internal assigned static IP
– 2x External routable internet IP addr’s * e.g 8.8.8.8 which most IT Pro’s utilise to ping to check internet connectivity
– 3x Internal IP addr’s owned by the NSG as VIP
|- 1x for MDM
|- 1x for MAM Gateway
|- 1x for Load-balancing IP
– Wildcard certificate for your domain e.g *.domain.com
– If your implementing SSL Offloading (HTTP) of your XenMobile traffic for MAM then you’ll require the devices cert from the XMS V/A which can be downloaded from the XMS Web AdminUI at https://xms:4443/

4: Setup the NetScaler Gateway configuration within the Admin WebUI of the XMS V/A following the process outlined at – http://support.citrix.com/proddocs/topic/xenmobile-10/xmob-netscaler-gateway.html its fairly straight forward and simple.
5: Login into the NSG Admin WebUI interface and click the XenMobile Wizard in the bottom left-hand corner and then you’ll be prompted to setup either XenMobile 9.0 or XenMobile 10.0 please selected XenMobile 10.0 and click “Get Started” to continue.
6: Ensure that “Access through NetScaler Gateway” which is for MAM, “Load Balance XenMobile Servers” which is for MAM are checked they should be by default, however you know have the opportunity to deselect either if one depending upon your deployment scenario/use case and obviously your acquired license. The current XenMobile 10 datasheet is available at –
https://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/citrix-xenmobile-the-revolutionary-way-to-mobilize-your-business.pdf.
7: Enter in your first VIP for the MAM Gateway then port should be 443 and provide a suitable name.
8: Select your previously uploaded SSL certificate (I am utilising a wildcard cert for my domain *.axendatacentre.com) or upload your SSL cert.
9: Create your (s)LDAP binding you will need to provide the following:

– LDAP IP addr
– LDAP Port default is 389
– Base DN e.g Cn=Users,dc=axendatacentre,dc=com
– Service account username & password
– Timeout default is 3 seconds
– Server Login sAMAccountName or UserPrincipalName (SuGgEsTeD)

10: Now enter in your MDM FQDN and then the Load-balancing IP addr beneath and accept the default port of 8443. You can now also choose to select HTTPS (SSL Bridge) vs. HTTP (SSL Offload) and you can choose your DNS mode including split tunnelling.
11: Select your previously uploaded SSL certificate (I am utilising a wildcard cert for my domain *.axendatacentre.com) or upload your SSL cert.
12: Enter in your MDM VIP and you’ll notice the default ports are 443, 8443 for communication to the XMS V/A(s). You’ll notice that you cannot change the SSL traffic configuration as I specified to not to perform any SSL offloading in set 10 above or its under section “Load Balancing IP address for MAM” within the NSG XenMobile 10 wizard.
13: Next add in the XMS ip addr’s of each V/A in your XMS cluster and provide an appropriate name and ports are automated defaulted to 443, 8443.
14: Click continue to finish and then click done and you have now setup and configured all your traffic for XenMobile to route through your NSG V/A and we are performing SSL Bridging in the above scenario.
