Understanding IaaS + Citrix Secure Digital Perimeter & Workspaces deployed in a Public, Hybrid or Private Cloud world powered by Citrix Cloud https://citrix.cloud.com/ + Serverless for Web Apps from LAMP by https://twitter.com/lyndonjonmartin
How do you enable your own personal Avatar within your Citrix Workspace? I will be honest its not obvious and its driven by the Citrix Content Collaboration (ShareFile) platform.
1.Login into your Citrix Files (ShareFile) portal e.g https://axendatacentre.sharefile.eu or .com 2.Once you logged in you should be taken to “Dashboard” UI and in the middle of the web page at the top you’ll see your name e.g “Lyndon-Jon“ 3.Next to your name it will say “Add profile picture“ 4.It will then open up the “Edit Profile” web page and within the “Name and Company Details” area you’ll see parallel to your name “Profile picture” select “Upload” and browse to the picture that you will use and select it.? 5.Your picture will be upload and a green notification will appear above (right side) saying “Your profile picture has been updated.” which means your profile picture has been saved successfully. 6.Next login to your Citrix Workspace either the app or HTML5 portal and you’ll see your personalised Avatar appear instead of the standard initials Avatar. Note I did find that Citrix Workspace app across all my devices required either more than 1x refresh to propagate the new Avatar or sign-off/close Citrix Workspace app and re-login at the change propagated.
In closing you now have a personalised avatar within your Citrix Workspace available across all your devices as seen below, although I primarily use Apple devices you can see the experience persists from a HTML5 browser to the mobile and desktop apps for Citrix Workspace.
I have not checked what feature entitlement is required but considering that you personalise your Avatar in Content Collaboration its a little obvious at a glance, I will update this article in the future once I have fully investigate the entitlement required. This feature had positive impact on me that I believed a brief post about setting it up was a priority for me to share with the Citrix community.
The views expressed here are my own and do not necessarily reflect the views of Citrix.
This is paramount to my productivity as I can get context externally from Citrix customers/partners and internally switch an email thread to a slack conversation(s) that are far more memorable and collaborative and if I or the other person is miss understood in anyway we can switch to a #SlackCall at the tap or click of a button and if necessary I can share my local vs. #virtualdesktop screen or view theres to get 360 degree feedback on a presentation, proposal e.t.c Check out – https://slack.com/apps/AAGN5FH9C-citrix-secure-mail to learn more today.
I’m often asked why Citrix? The answer can be a simple vs. complex one, therefore I choose to demonstrate why Citrix through proactive evangelism by recording myself using my Citrix Workspace actively through-out the year, which initially began in 2016 and lead to the original How vs. where I worked from in 2017 video available at – https://twitter.com/lyndonjonmartin/status/949316537021812736.

What is Citrix Workspace app? It brings together all your LOB tools which in todays modern world consists of (virtual/micro/installed/mobile) apps, SaaS, desktops & content. I’ve embedded a sample of what this actually looks like below.
The new Citrix Workspace app way more than purely an upgrade of Citrix Receiver e.g grey to blue icon and a skin change, this NEW Citrix client app release is simply extraordinary, working for Citrix I can be considered bias however once you actually begin to consume the Citrix Workspace app you’ll understand exactly what I mean. Citrix Workspace app is for me all about an experience, and that experience is extraordinarily AWESOME! As I begin consuming my LOB (Line of Business) tools wherever I am + want and in a setting/context that suites me (home, Paddington vs. partner offices, trains, taxi e.t.c) the chosen LOB tool delivered context can change dependant upon criteria (I won’t be covering this today) or how IT (say YES!) has chosen to deliver the LOB tool through Citrix Access Control Service – https://docs.citrix.com/en-us/citrix-cloud/access-control/get-started.html.
I now have all my content available all in the same AWESOME app thank you Citrix Content & Collaboration aka ShareFile. I can upload, download and even favourite particular content e.g “L-J’s H1/2 Citrix Partner Tech Super Deck” which is then available directly from the home view/tab. In the below example I am uploading the LeasePlan Citrix SD-WAN case study – https://www.citrix.co.uk/customers/leaseplan-en.html and the actual video is available at – https://www.youtube.com/watch?v=4Hq-yryxfS0 take a look and remember to listen to the outcomes Citrix SD-WAN provides LeasePlan.
How do I get started today?
Firstly I will do a more detail blog post on getting it all up and running with use cases time dependant of course.
1.Start by navigating to https://docs.citrix.com/en-us/citrix-workspace-app.html and then goto Citrix.com and login with your access details, next navigate to https://www.citrix.com/downloads/workspace-app/ and download Citrix Workspace app for your chosen end-point. If you are running a TP of Citrix Workspace app code base please UNINSTALL it prior to installing the GA production code base as a few community individuals I know had issues upgrading from TP code base. I would like to state for the record I upgraded from PRODUCTION Citrix Receiver to the Citrix Workspace app for Mac 1808 on my Mac without ANY issues see below tweet.
5. Sign-up vs. Login to Citrix Cloud today and trial vs. acquire a Citrix Cloud service e.g ShareFile Service or the XAD Service and if you want to aggregate on-premises LOB apps into the new Citrix Workspace experience then setup “Site Aggregation” today. To learn how please read this CTXS blog post and watch the embedded YouTUBE video which provides a how-to overview at – https://www.citrix.com/blogs/2018/08/03/site-aggregation-for-citrix-workspace-is-now-ga/.
Thats all folks for now on the technical overview its brief I know so I will follow-up in future with more detailed overview + how-to e.t.c either here or on the https://www.mycugc.org website in the experts area.
Upgrading to Citrix Workspace from Citrix Receiver for smart devices
I work for Citrix, I have been a Citrix + IaaS advocate for well over a decade (now SD-WAN swell) so I am mostly likely bias you’ll think however Citrix Workspace app is truly AWESOME and way more than what you see at a glance, I encourage you all to begin consuming it today to see for yourself just what I am talking about and why I personally say its “AWESOME“.
Its that time of the year where you Citrix customers, partners can vote for your favourite Citrix Innovation Award Finalist.
This year see’s a great mixture of customers in different markets all leveraging Citrix technologies as the enabler for transformation within there organisations to embrace a new way of working or #ThisIsHowTheFutureWorks powered by Citrix Networking, Workspace and Security & Platform Analytics from https://www.cloud.com/.
I would encourage you to watch all three videos describing there journey before casting your vote as there is some really great innovation happening within these Citrix customers and if you want to get started visit https://www.citrix.com or https://www.cloud.com/ today.

Introduction to “Session Watermark”
The latest release of the XenApp & XenDesktop Service powered by Citrix Cloud or if you are performing a private cloud (on-premises) upgrade or net new installation of XenApp & XenDesktop 7.17 has some NEW features (another post brewing) and one that I have been waiting on for quiet sometime now has not finally arrived (WAHOO!) and its VERY VERY simple to configure and aids in improving your security posture (I believe) for delivery of apps & desktops powered by Citrix against e.g IP theft. In the below tweet can you see it?
The above is from my initial tests using a Windows Server 2016 VM hosted in Azure Northern Europe region running the 7.17 VDA configured to my Citrite #CitrixCloud XenApp & XenDesktop Service so I did not need to upgrade anything to get this new SHINY cool feature yes I said it SHINY. All I was required to do was deploy a new Windows Server 2016 VM from the Azure marketplace, domain join it, install the VDA and connect it to my Cloud Connector and I was ready in less than 25 minutes from initially deploying the VM from the marketplace.
Finally on a personal note for me Citrix SysAdmins enabling the “Session Watermark” feature obviously initally tested in a safe environment e.g UAT with a few users from a couple of departments and then rolling it out into production (as when/how your ready) will be making IT the modern “App & Desktop Security Heroes“. IT can apply and configure these new policies to be the most right vs. relevant for your organisations security needs while not hindering the end-users Rich HD eXperience.
Before we get started it is worth mentioning that this feature does add an overhead to the compute on the backend (VDA side) and therefore it is suggested to enable up to two water marking features or items. In my overview of this feature I will wont cover off the cost of implementing this security policy as there are multiple variables to consider e.g HDX Graphics Mode and associated policies to provide the right vs. relevant end-user experience vs. how many watermark items do I apply? I have begun testing so bare with me and I’ll publish my findings either on my personal blog here or on https://www.mycugc.org under the “Expert Insights” area.
“Enable session watermark”
By default this feature is DISABLED as the default behaviour which I believe is the right approach considering its Citrix’s initial release of this #security feature (in my personal view) and secondly online documentation at eDocs suggested recommendations it to enable NOT more than two watermark text items. Finally * indicates that this policy is DISABLED by default when Session Watermark is enabled.
Include client IP address
* This is the IP addr of the device connecting to the virtual app & desktop.
Include connection time
* Utilises the following format yyyy/mm/dd hh:mm to display the users initial connection time to there virtual app or desktop.
Include logon user name
ENABLED by default when you enable Session Watermark as a policy and uses the following format USERNAME@DOMAINNAME is most optimise for 20 characters or less otherwise truncation might occur of the users logon username.
Include VDA host name
ENABLED by default when you enable Session Watermark as a policy and provides the VDA hostname e.g ne1vad01
Include VDA IP address
* Provides the internal IP addr that corresponding the VDA’s hostname e.g ne1vad01 = 10.1.0.7
Session watermark style
ENABLED by default using “Multiple e.g displays five watermark labels” when you enable Session Watermark as a policy or you can configure “Single e.g displays a single watermark label in the centre of the session“. TIP switching to SINGLE and sticking to two watermark text items for me in my initial tests is a good starting policy however time will tell as I continue to test out this new feature and its capabilities with different HDX Graphics Modes and associated tweaks.
Watermark custom text
* A unicode maximum of 25 characters is supported if you exceed this limit it will be truncated.
ENABLED by default set to “17 out of 100” when you enable Session Watermark as a policy, personally I think setting it to just 1 is fine in my initial tests as you want it to be not so in your face to the end-users to be bluntly honest.

Please be aware that I published this article today 19/02/2018 but it should be considered evergreen until I remove this section thank you.
This is going to be one of the longest posts that I am about to write so come back from the moment its published over Feb/March/April 2018 as I will most likely be making adds/moves/changes. This blog post serves to provide the most right vs. relevant information to help you better understand how-to deploy the current Citrix XenMobile on-premises server which is 10.7.x.n as of February 2018. I will be writing a follow-up blog post on deploying the XenMobile Service powered by Citrix Cloud – https://citrix.cloud.com/ in due course.
What is XenMobile?
XenMobile is a complete UEM or MEM via https://twitter.com/JJVLebon (mobility) solution for managing apps, data, and devices from a single unified platform with MDM & MAM (mobile apps cut, copy & paste) policies, automated actions for enrolled (supported platforms) devices that will keep employees safe, secure and productive on vs. offline enabling them to work on there own terms.
Preparation & Initial Guidance
I was one of the first set of individuals to pass the very first Citrix Certified Professional – Mobility (CCP-M) exam for XenMobile 9.x.n while at Citrix Summit in Jan 2014. Now that was one very tough exam as you needed to know Citrix NetScaler, XenMobile NetScaler Connector, (ZenPrise) XenMobile Device Manager, StoreFront, Citrix Mail Manager, Citrix AppController, ShareFile Control Plane and of course StorageZones. Its Fen 2018 and its still equally a tough exam to pass even though the XDM + XAC where merged into a virtual appliance now called the XenMobile Server (XMS).
If you have not deployed a mobility solution in the past or your an expert you’ll agree most likely that mobility or UEM/MEM is complex and is consistency changing with new devices, OS upgrades along with new vs. deprecated vs. behavioural changes to MDM APIs, app updates, push API’s vs. MDM platform + vendor signing of certificates and finally oh yes all those MDM ports that you need configured correctly through-out your organisations Wi-Fi network and so the list continues on and on….
In principle when preparing to deploy any mobility solution regardless of vendor, preparation is of paramount important to be successfully. The below is list of how I personally prepare for a mobility PoC for XenMobile on-premises (yes we at Citrix are cloud first and I live IaaS so I’ll be writing another post on deploy a XenMobile Service PoC in the future):
– Start by reading the XenMobile Security Whitepaper – https://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/xenmobile-security-understanding-the-technology-used-by-xenmobile.pdf. This will provide a great insight into our XenMobile, FIPS compliance, how SSL VPN or mVPN for MDX enabled apps behaviour and so much more, that is definitely worth your time!
– Configure the XMS with a public routable FQDNand NOT an IP addr if you intend to manage devices externally via the internet vs. internally over corporate Wi-Fi and if your enabling the self-help portal for personal management.
– Utilise the PostgreSQL database option for a PoC’s (up to 100 devices) however this will mean that you need to redeploy the XMS using a remote SQL database for PROD environments as you’ll most likely want to have your XMS v/a in a cluster for high-avaiability. NOTE: Do not pre-create a MS SQL database allow the XMS v/a to create your MS SQL database against the SQL server during the initial setup process when performing the initial FTU within the XMS CLI.
– Utilise local v6 licensing on the XMS v/a for a PoC’s but again for PROD utilise a remote Citrix licensing server which is 100% required to support a XMS Cluster as the XMS v/a are stateless with all the configuration held within the remote Microsoft SQL database.
TIP: You’ll need to active your XenMobile licenses from the available list when configuring the remote v6 license server prior to continuing!
– Create separate mobility admin mailboxes to then be used to create accounts with Apple, Google & Microsoft so that everyone has access to create, sign and revoke MDM push certificates vs. push API’s like FireBase.
– Deciding where to generate all of CSRs for all of your mobility + XMS + NS certs is quiet important not just for the initial PoC but thinking 12 months out when the cert begin to expire where did I generate those certs from now to begin the re-signing process hmmm….??? I prefer in my home lab to generate and renew all my certs on WDC but many SE’s I know will use NetScaler for this and the point I am making is that it does not matter BUT centralise and document the process, passwords e.t.c
– Setup a calendar invite vs. trigger in your choosen support platform to notify the mobility admin mailbox to alert you every 11 months to renew all your certs otherwise you’ll break your MDM deployment e.g no devices under mgmt anymore this applies to ANY MDM vendor to be 100% clear!
– Dont assume that one individual should be deploying the XenMobile (any mobility) PoC themselves as in my experience unless your 100% comfortable with networking, ACLs, SQL DBs, gateways. To be honest most often its 3 people from within the IT team for high security organisation its double I find. Typically the 3 people are the Citrix Admin whom will require help & support from a networking (f/w dude:-)) or netscaler admin and then the SQL guru.
– I typically advise partners and customers to focus and agree on 2x mobile devices and a defined list of UEM policies to configure for testing in the PoC against there use case(s).
– Ensure that all your required ports are opened up correctly in vs. outbound (internet <-> edge <-> dmx <-> tru).
– DO NOT USE A PROD NetScaler deploy a new and fresh NetScaler VPX for your XenMobile (Service) PoC on-premsies vs. your chosen resource location.
– If you are intending to MDX wrap or enlighten your iOS – https://developer.apple.com/programs/enterprise/ and Android mobile apps then I’d suggest that you sign-up for the required developer accounts well in advance as some customers & partners have experienced delays up to 1-8 weeks. You have been warned and also ensure that you understand the rules around these dev accounts!
– Disable the ability to perform a Full Wipe of the enrolled devices (in particular for BYO scenarios you don’t want a lawsuit!) or if your not bothered and you would like to test this capability then I’d suggest that you only use new mobile devices that contain no corporate vs. personal content + data during the PoC. Finally my own personal leading best practise is to setup RBAC for mobility admins and remove the full wipe capability completely! 🙂
– Screen record the PoC deployment e.g GoToMeeting so if you make a mistake you can review the recording to understand what you misconfigured and most importantly where on the NetScaler vs. XMS e.t.c is was that the mistake occurred.
– If your not going to utilise a public CA signed certificates (Strongly Preferred) as your deploying the XMS v/a in your home lab only, then when exporting your cert from your Enterprise CA export using the Base64 format and then export as a full chained PFX format cert.
– Deploy the XMS v/a first and attempt to enrol your chosen mobile device(s) and remember those MDM ports you’ll need to make sure they are available over your corporate wifi including the over air enrolment port especially for Apple iOS devices otherwise your MDM enrolment will fail so you’ll be defaulted to only been able to enrol your device for MAM only e.g Secure MDX enlighten mobile apps
– The XMS mgmt. Web UI for administration is restricted from the internet as the mgmt. web UI is only accessible over https://XMS:4443 which is not part of the XM 10 wizard as of e.g NSG 10.5-55.8+ for security harden purposes (double check eDocs to be safe!). This often leads to Mobility/Citrix Admins thinking that they have misconfigured the wizard on the NetScaler when in fact it most likely is your connecting connection on https://XMS-vip:4443 via the VIP owned by the NetScaler but if you connect directly to the XMS’s configured IP addr via https://XMS-direct:4443 you’ll be able to access the XMS Admin Web UI.
– SuGgEsTeD personal tip utilise Mozilla Firefox for configuring and managing your XMS v/a for me it works the best!
– Ensure that all users/admins have first, last name & e-mail addr fields populated in AD prior to any enrolment otherwise they will receive an error e.g “Invalid user for SSO” when users attempt to sign-on.
– APNs see below
– SSL Listener used for HTTPS traffic communication e.g like securing your web server with https
– Open up 389 between the XMS v/a(s) and your AD server in your trusted network, you can optionally configure secure AD/LDAP on 636 but you will required extra certs for this configuration and its well documented in Citrix eDocs vs. obviously I believe.
– Windows service account for XMS v/a(s) to query AD/LDAP
NetScaler (Unified) Gateway
– Versions 10.5.x.n, 11.0.x.n, 11.1.x.n and 12.x.n (My current preferred firmware release now)
– 2vGPU, 4GB of RAM and 20GB available storage for HDD
– On-premises Hypervisors include XenServer 6.5 or 7.x.n; VMware ESXi 4.1, ESXi 5.1, ESXi 5.5, ESXi 6.0; Hyper-V Windows Server 2008 R2/2012/2012 R2
– Cloud Hypervisors include Azure (ARM is preferred); AWS EC2 not supported for XenMobile.
– NetScaler service account I’d advise against the default which is nsroot:nsroot slightly obvious but I see this time and again can you believe it!!!!
– AD/LDAP service account that is utilised to check validate and authenticate users against your organisations AD/LDAP.
– IP addressing (Please please please pay attention)
1x private static IP addr that is used for the NetScalers IP Addr (NSIP)
1x private static routable IP addr between your DMZ <-> TRU which is referred to a the NetScalers Subnet IP Addr (SNIP)
1x private static IP addr that is used for the XMS
1x public internet routable FQDN e.g uem.axendatacentre.com with 1x public static internet routable IP addr that resolves to 1x private static IP addr in your DMZ that are owned by the NetScaler.
1x public internet routable FQDN e.g mam.axendatacentre.com with 1x public static internet routable IP addr that resolves to 2x private static IP addrs in your DMZ that are owned by the NetScaler one for direct NAT and the other one is for *L/B of the MAM traffic.
1. Create an organisation Apple ID at – https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/wa/createAppleId
2. Generate your a CSR on NetScaler – https://support.citrix.com/article/CTX211887 or on a Windows Server e.g WDC using e.g IIS NOTE: Please use 2048 cipher encryption for the cert.
3. Navigate to https://xenmobiletools.citrix.com/ and sign in where prompted with your Citrix.com partner access details.
4. Follow the onscreen process for signing your XenMobile APNS CSR which will return a *.plist file.
5. Login to and upload your CSR to the APNS portal at – https://identity.apple.com/pushcert/ by following the onscreen process.
6. Download the generated *.pem file from the APNS portal to the Windows server that you initially created the CSR on.
7. Import the *.pem file into IIS using the complete a CSR response and specfic a friendly name. NOTE: Optional Import Apples Certificates (*.cer, *.crl) from – http://www.apple.com/certificateauthority/ also see http://support.apple.com/kb/ht5012
8. Export the imported certifcate as a *.pfx and specifiying a password. Note: DO NOT FORGET the password.
9. When prompted during the XMS configuration of the WebUI rememeber to enter the your chosen password and import it’s a keystore -> pfx format and select aPNS as the cert type.
Firebase Cloud Messaging (FCM)
Google or FireBase Cloud Messaging (GCM or FCM) enables push capabilities for Android vs. implement during enrolment an “Active poll period policy” for the Android handset to check back into the XMS to receive new policies, apps, check compliance e.t.c. Finally note that if you do any research FCM https://firebase.google.com/docs/cloud-messaging/ is the natural evolution of GCM platform, so think FireBase first for Android :-).
1. Create a organisation Google Developer account at – https://console.firebase.google.com/?pli=1, if your keen to understand how it works visit the XenMobile eDocs web page for Firebase at – https://docs.citrix.com/en-us/xenmobile/server/provision-devices/google-cloud-messaging.html.
2. The process to create the push capabilities is in my personal view way easier than APNs as all you need to do is generate an “API Key” and “Sender ID” which is then stored on the XMS at “Settings – > Google Cloud Messaging“. Visit the above URL to learn how to implement Firebase.
3. Please pay attention to the Firebase XenMobile diagram in the above eDocs link which includes the following Firebase ports 5228, 5229 and 5230 between the enrolled XenMobile handset and the GCM platform. Why is this important well these ports will beed to made available from the corporate network outbound like APNs to enable enrolment from within the corporate enterprise or high security environments otherwise you will need to enrol over 3/4G or via home/guest Wi-Fi.
Deploying the XMS v/a
Before you even attempt to begin I’d strongly advise you to read and or print out the following webpage via Citrix eDocs – *https://docs.citrix.com/en-us/xenmobile/server/install-configure.html which contains a Preinstallation checklist and deployment flowchart. My goal in this section to provide some context with some of the deployment options during the initial configuration of the XMS v/a, you can refer to * for full installation instructions.
1. Download the current XMS 10.7.x.n+ v/a from – https://www.citrix.com/downloads/.
2. Unzip the v/a and upload it to e.g Citrix XenServer 7.1 LTSR via XenCenter or you could use any other Citrix supported on-premises hypervisor. Once successfully uploaded check that your v/a has the minimum required computed requirements 2-4vCPU and 4-8GB of RAM assigned (increase to MAX if 10 or more users in the PoC as its all about the experience but for home lab purposes I utilise 2vCPU and 4GB of RAM as I only have 3 devices connected.
3. Start the XMS v/a via XenCenter it will take longer to boot-up if you have assigned the bare min compute resources and if your underlying storage is (shared) HDD based.
4. Once the XMS v/a has started decide if you are intending to create a XMS h/a cluster this is so that you select the correct options during there FTU, otherwise you will need to redeploy the XMS v/a and start all over. Notes:
4.1 – The CLI uses admin while the Admin account used for the Web UI uses administrator, also be aware they are LOWER CASE!
4.2 – Nothing appears when typing in select inputs.
5. Enter in a strong suitable passwd
6. Next you are promoted for network settings the IP addr will be e.g 10.1.0.99 as per my text diagram above.
7. Next your asked about an “Encrypting Phrase” most people select “y” to randomise it however you’ll never know what it is, nor can you obtain file to read it! If you are considering deploying a cluster of XMS v/a for H/A then most individuals will select “n” and create there own “encryption passphrase“.
8. I currently at the moment will not provide any context on FIPS so I will differ to https://docs.citrix.com/en-us/xenmobile/server/install-configure/fips.html#par_anchortitle_8dcb for configuration options otherwise this blog will get out of hand. I will do a follow-up or adjustment to this post in the future to cover FIPS in greater detail.
9. Next your asked about configuring a database for the v/a to store configuration information. The “l – Local” option will enable PostgreSQL which is now only supported for customer PoC’s while historically prior to Citrix acquiring ZenPrise is was a supported configuration but that was 5+ years ago under XDM, so be 100% clear PostgreSQL is for PoCs ONLY with a XMS v/a! It is also NOT supported with XMS clusters as the v/a’s are stateless relying on the SQL database for configuration information e.g users, policies, delivery groups e.t.c so you require a “r – Remote” SQL database.
9.1 – Let the first XMS v/a that you configure as part of the your XMS cluster create the required XM database itself DO NOT pre-populate a database name on your MS SQL database cluster vs. server!
9.2 – If you select to enable XMS clustering you will need to enable port 80 within the XMS f/w ACL and do this BEFORE performing a clone to create your XMS cluster. Also in high security environments remember to include in your submitted ACL to allow the XMS v/a’s to communicate over TCP port 80 to enable R-T comms between all v/a members within the cluster.
9.3 – Finally Citrix does NOT support DB migration e.g PoC to UAT-PROD environments.
10. The most important step that I often see vs. hear vs. receive requests about is what do I type in for the “XenMobile hostname”? Please type in the fully qualified and internet routable FQDN e.g uem.axendatacentre.com, what does this mean? It means that if your where to type in uem.axendatacentre.com on your device that you reading this blog post inside the corporate file or at home it is reachable. Please do not type in e.g xms01 and then internal vs. external DNS entries are entered in for uem.axendatacentre.com to xms01 this will NOT work properly and devices will NOT enrolling you have been warned! If you do this you will beed to START all over with a fresh XMS v/a!
11. For the XMS comm port requirements i.e the v/a communicates with the users (SHP) and devices (UEM or MDM/MAM) it is perfecting fine to accept the defaults ports here unless you a high security organisation + e.g Bank, Government agency e.t.c and want to further harden yourself however remember the most complexity you add e.g changing ports here will mean that you will need to adjust the auto defined ports on the NetScaler if you do the XenMobile Wizard on the NetScaler v/a.
12. Skip the upgrading from a previous XMS version as its a PoC
13. Next we get to the Public Key Infrastructure (PKI) which I’d prefer to configure configure all the certs with the same passwd or pass phrase or you can define a different passwd or pass phrase for each of the four certs (root, intermediate for device enrolment, intermediate for SSL cert and finally an SSL for your connectors +. Finally you’ll require the eXaCt passwd(s) for an XMS v/a within your h/a cluster.
14. Finally now create a passwd for the default “administrator” account. I would personally as my own leading best practise make the CLI admin vs. Web UI administrator passwords different for security purposes as one member of the team maybe the hypervisor admin whom does all the CLI stuff aswell while the Mobility admin handles all the logical configuration via the Web UI administrator account.
15. Once you select “Return” to above set the initial configuration is stored and you are prompted to upgrade from a previous release please select “n” which is also the default! The XMS v/a will stop and start the app and once its completed the you see a FQDN e.g https://10.1.0.99:4443/ this now indicates that you can complete the Web UI part of the XMS v/a setup and configuration. Note this can take up to 5-7 mins dependant upon how much vCPU, RAM that you assigned to the v/a and if your on SSD vs. HDD storage this will speed up the process naturally.
16. The biggest mistake Mobility/Citrix Admins makes with XenMobile is that when they attempt to access and configure the Web UI part of the setup they will typically access it via the NetScaler owned VIP for uem.axendatacentre.com <-> 81.x.x.1 <-> 10.1.0.20 when they should be accessing the direct IP addr of the XMS v/a <-> 10.1.0.99. Most individual do this to test there NetScaler setup, please DO NOT setup the NetScaler do it after you have setup the XMS v/a. Finally the reason you can’t connect to the Web Admin UI via the NS VIP e.g https://uem.axendatacentre.com:4443 either internally or externally is that the NS disables 4443 via the VIP to harden and protect the Web Admin UI from the Internet so you’ll need to connect to the direct XMS v/a <-> 10.1.0.99 IP addr on https://10.1.0.9:4443. Once your at the login prompt of the Web UI type username “administrator” and your chosen passwd and “Sign-in” and the “Get Started page” appears only once to complete the Admin Web UI part of the XMS v/a setup and configuration.
17. The first web page provides an overview of the available licensing configuration options, for a PoC or if its your first time using XenMobile then I’d suggest that you utilise the built-in 30 day evaluation license to give you time better understand how to configure XenMobile so that you can enforce the required UEM policies against devices vs. (MDX) apps. If you intend to deploy a XMS h/a cluster then like the XMS database you’ll need to setup or make use of your existing remote v6 Citrix licensing server however IMPORTANT make sure that this lic server version meets the minimum release requirements of 11.12 for 10.7.x.n XMS firmware/release version. If you choose to use the 30 day trial LOCAL license servers on XMS and now wish to use a REMOTE lic server then please refer to https://docs.citrix.com/en-us/xenmobile/server/system-requirements/licensing.html. I would also suggest to test from each XMS v/a(s) within your cluster that you can successful connect to the remote v6 lic server which is available under the Wrench icon -> Licensing. 18. Next its cert mgmt. and a word of caution as this catches everyone out is that after uploading any certs reboot the XMS v/a(s) is required in order for the new certs to bound to the SSL listener interfaces and the existing ones to be unbind! You’ll need at this point your APNs and SSL certs for e.g uem.axendatacentre.com to upload the XMS v/a when importing your certs follow:
Keystore Type: PKCS#12
Use as: APNs and or SSL Listener
Description: Date uploaded and what is it? APNs vs. SSL listener?
Wrench icon -> NetScaler Gateway
Authentication: ON (default)
Deliver user certificate for authentication: OFF (default)
Credential Provider: (default)
External URL: https://mam.axendatacentre.com
Logon Type: Domain only (default)
Password Required: OFF (default)
Export Configuration Script: Allows you to download conf bundle to upload to NUG to configure XenMobile. I prefer to do this manually myself.
Next add the following to your NetScaler Gateway configuration on the XMS.
^Callback URL: FQDN to verify that the request originated from NetScaler Gateway BUT make sure the callback URL resolves to an IP addr that is reachable by the XMS v/a(s)
^Virtual IP: 10.1.0.21 (See text diagram above in HTML table format)
^ These settings are optional.
20. Next your promoted to setup your AD binding I always prefer using an FQDN vs. IP Addr here as IP addr’s can change however FQDN’s typically don’t otherwise a lot of things in your environment will break.
Port: 389 (Leave defaults unless changed within high security environments)
Domain name: axendatacentre.com
User Base DN: ou=Users,dc=axendatacentre,dc=com (I am just using the AD default location of the Users OU here when you would have setup AD so configure to meet your organisations default OU location of Users)
Group Base DN: cn=Users,dc=axendatacentre,dc=com
User ID: XMS AD service account used to query your AD e.g firstname.lastname@example.org
Domain Alias: axendatacentre.com (yours maybe different)
XenMobile Lockout Limit: 0 (default)
XenMobile Lockout Time: 1 (default)
Global Catalog TCP Port: 3268 (default)
Global Catalog Root Context: (default)
User search by: userPrincipalName (preferred for the modern world)
Use secure connection: (default)
21. Final configuration you’ll need to do is to setup XMS notifications – https://docs.citrix.com/en-us/xenmobile/server/users/notifications.html which is required for things like bulk enrolment (users e-mail addr must be in AD field), communicating with users when automated actions are configured and users have violated your organisations UEM strategy.
22. Now please logout of the Web Admin UI and log back into the XMS CLI via your chosen hypervisor and follow the below instructions to reboot your XMS v/a
Your XMS v/a will begin to restart and once it is successfully rebooted navigate to the XMS v/a direct FQDN https://uem.axendatacentre.com or IP addr and check that the HTTPS cert status in your internet browser to ensure that it is no longer self-assigned by the XMS v/a but matches your uploaded SSL cert bound the SSL Listener.
Troubleshooting & Leading Best Practises
1. Citrix provides a XenMobile tools platform available at – https://xenmobiletools.citrix.com and also be sure to please refer to XenMobile compatibility documentation – https://docs.citrix.com/en-us/xenmobile/server/system-requirements/compatibility.html for compatibility of devices vs. MDX apps + release versions.
2. Users receive Profile Installation Failed The server certificate for “https://XM-FQDN:8443” is invalid when enrolling a device against XenMobile when using iOS devices. I have personally have not seen this issue occur again for quiet some time but I thought its worth including encase it reappears in the future. So what causes this issue? It is to do with the private key of your *.p12 or *.pfx full chained SSL/TLS cert and appears to only occur when exporting your cert from a new CSR on a Windows OS. To resolve the issue I’d suggest that you download, extract and run the DigiCert Certificate Utility available at – https://www.digicert.com/util/ on the originating windows server that you generated your CSR on for tier XMS v/a for your SSL Listener cert e.g HTTPS. Next follow the guide available from Digicert at – https://www.digicert.com/util/pfx-certificate-management-utility-import-export-instructions.htm to help you find and export your XMS v/a HTTPS cert correctly (advise to use TEST feature button before export) and re-upload it to the XMS v/a and remember to REBOOT the XMS v/a(s) when you change any certs on the XMS v/a(s)!!! You should now be able to begin re-enrolling your devices BUT I would strongly advise to remove any MDM certs via Settings in iOS and then delete SecureHub and re-download it and now the enrolment error messages should no longer appear to your users while enrolling there iOS devices.

Introduction what is HDX?
High Definition eXperience (HDX) is a set of technologies that provides a near to HD local like experience of a remoted virtual app, desktop or both to users anywhere in the world on any device even without installing anything on that device all you need is a modern widely used (supported) HTML5 compliant internet browser e.g Chrome, Safari (try it on your iOS devices :-)), Firefox, Internet Explorer you get the picture.
HDX is simple yet so powerful and has three founding principles which are intelligent redirection, adaptive compression, and data de-duplication like wise it has three principles it performs when you connect to there virtual resources which is Inspect the VM (Server vs. Desktop) what does it have e.g vGPU, Inspect the network what its like and can I use UDP for adaptive transport or should I fallback to TCP to remote the display + multimedia and finally it inspects the end-point what is there and can I use it? An example is the HDX Optimisation Pack available to offload audio/video for my Skype for Business sessions or shall I utilise generic HDX fallbacks?
– The release of XAD 7.16 introduces a great new VDA installation behaviour change 🙂 whereby it will automatic set the HDX mode to be standard (Server OS) vs. HDX 3DPro mode (Desktop OS if it meets the requirements for HDX 3DPro e.g the Desktop OS includes a vGPU or GPU) which I believe is setup in the right direction and simplifying overall CTX Admin overhead e.g another syntax option to remember vs. I forget to configure the correct parameter.
– Now by default the new HDX Graphics mode is enabled is adaptive transport or EDT and is set to Preferred. Don’t worry if your a Citrix Admin as you’ve maybe already realised I didn’t enable UDP for this to work! Remember is an adaptive remote display protocol so it will fallback to TCP by default using the default Citrix HDX ports. Its also worth mentioning that when (Preferred) is set then SR is enabled for both UDP vs. TCP connections and client connections (Receiver check supported versions e.g Win min 4.10; Mac 12.8) are attempted in parallel during the initial connection, for SR reconnections and finally auto client reconnects aswell.
– Browser Content Redirection – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/multimedia/browser-content-redirection.html redirects the contents to the local device running an embedded browser within the HDX session which allows for offloading of content, network traffic, graphics from the VDA running in the resource location to the users end-point enhancing the UX significantly.
– Not strictly something new but HTML5 Redirection – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/policies/reference/ica-policy-settings/multimedia-policy-settings.html which is still currently only available for internal usage as you’ll read from the eDocs article but this is 100% something an Citrix Admin & Architects should begin testing today as HTML5 begins in my personal view to supersede Flash based websites as we move forward towards 2020.
– Auto DI Scaling for Multi-Monitor
– H.265 encoding support running on the latest end-points which supported a GPU that supports H.265 decoding and if its not available it will by default fall-back to H.264 decoding. The net result of moving to H.265 from H.264 which is a Platinum only feature results in significant bandwidth savings and much better UX. I have seen the net results with a few of our engineering customers that develop vehicles with teams spread out across the world and the results as awesome!
– Strictly speaking this is not agnostic or exclusive to the HDX technology stack but the Windows Continuum is quiet important for a great user experience and its powered by primarily at a the hypervisor level and its currently only supported on Citrix XenServer. Visit – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/technical-overview/hdx.html for how-to configure it today if your running XenServer.

I thought i first start off with a tour of Secure Notes followed on by my personal views and thoughts of using Citrix’s Secure Notes thereafter.
Tour of Secure Notes
1. You can login from a web browser at http://securenotes.citrix.com and if you want to sign-in via your organisations IdP select “Log in with my company credentials”
2.Enter in your organisations ShareFile subdomain e.g MyOrgName
3. It will redirect you to you’re organisations IdP login where you will be prompted for a username + password and potentially another form of authentication like a receiving a telephone call, virtual token or asked to verify yourself using your biometric authentication.
4. Once you are signed in your can begin creating a note (secure website version of Secure Notes) by providing it a heading and then in the body text your notes or drag and drop pictures, tag your notes and assign it to a notebook (collection of notes perhaps by project vs. organisation vs. team meetings e.t.c), delete unwanted or irrelevant notes, set a reminder against a note, favourite the note or search of other notes that you’ve created.
5. Now you can see in this image that I have been using for sometime now its still less than 30 days but I’m using notebooks to assign my notes by partner, customer vs. major events and i’ve tagged selective notes that require a follow-up and then I remove tags once its completed.
6. I have switched to the Notebooks view from theAll Notes which organises your notes based upon your created notebooks in my case by customer, partner & events and then I assign my notes to these notebooks so i can easily navigate notes for example by a partner or just use the search filter (whats right vs. relevant to you).
7. All your notes are stored securely within your ShareFile personal folder, and if your using Drive Mapper with your Citrix virtual apps & desktops the path to see your notes is at – “S:\Personal Folders\WorxNotes.root” and it does not matter whether your creating your notes using the website version of Secure Notes at – http://securenotes.citrix.com or even if you create your notes using the secure XenMobile enabled app called “Secure Notes” which is available from the public app store for iOS – https://itunes.apple.com/us/app/citrix-secure-notes/id1157570015?mt=8 and Android – https://play.google.com/store/apps/details?id=com.citrix.note.droid&hl=en_GB and controlled by XenMobile MDX technology to stop cut, copy and paste. You can learn more about MDX by reading the XenMobile security white paper available at – https://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/xenmobile-security-understanding-the-technology-used-by-xenmobile.pdf.
8. If I now switch to a mobile world and I mean using a smart phone or tablet and for convenience sake I’ll be using the Secure Notes app I can see that I have the similar same capabilities and functionality vs. the secure website versions.
9. I can insert a picture, tag it, favourite it, set a reminder e.t.c but now I can record audio.
10. I can create my notes offline and when your back online it will sync your note(s) back up to ShareFile and you’ll notice the red cloud icon disappear.
11. Send your notes as an embedded message within Secure Mail body vs. PDF file attachment by selecting your preferred choice.
1. Currently only iOS 9-10, Android 5-8 phones BUT its not supported on Tablets!*
2. Selecting a storage location for your notes upon setting up the app your asked if your prefer to store your notes in Microsoft Exchange Server or for your Secure Notes + within a ShareFile StorageZone. You can provide users with a choice of both upon on-boarding within the Secure Notes app.
3. Once users have been setup the XenMobile Secure Hub agent can handle SSO or push the app to users whom have enrolled into XenMobile’s MDM.
4. Supported file formats include – *.M4A, *.JPEG, *.PNG, *.BMP, *.GIF, *.WebP for rich editing experience.
