What is an Apple Push Notification service (APNs)Certificate and how does it work?
APNs certificates allow and enable for the safe, secure propagation of information/notifications to iOS and OS X devices with source of information/notifications originating from a XenMobile Server with a trusted and signed APNs certificate by Apple and Citrix. In this particular overview I am referring to MDM/Mobility vendor’s e.g Citrix, Airwatch by VMware, MobileIron etc.

APNs certificates allows any end-user to enroll his/her iOS device (iPhone, iPad) weather it be corporate or personally owned (BYO) against a XenMobile Server in order to obtain organisation specific configurations e.g Wi-Fi configurations and of course security leading best practise policies e.g the users PIN must be alphanumeric, 6 characters in length and must be changed once every 90 days to meet organisation password policy guidelines etc.

I wont attempt to explain how APNs certificates work technically I do understand it but I believe Apple’s documentation is simple very clear to understanding and provides a great overview of how APNS works and functions so please visit the following links – https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html#//apple_ref/doc/uid/TP40008194-CH100-SW9.

Creating and renewing an APNS Certificate with IIS (SuGgEsTeD for PoC Environments + Draft)
0: You will require a valid Citrix partner account to access your Citix My Account – http://www.citrix.com/account.html and you will require a valid Apple ID to login into the APNs Portal to complete your APNs signing request and for on-going APNs maintenance i.e. renewing, revoking your APNs certs. If you do not have a valid Apple ID you can create one at the following link – https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/wa/createAppleId.
1: Prior to creating your APNs cert you should consider the following which is will your customers PoC ever move to a pilot or event to production? If it may then you/they should carefully consider exactly where you will generate your Certificate Signing Request (CSR) for your APNs certificate to be used with the XenMobile.
2: Open up IIS on your chosen Windows Server and click Server Certificates and select “Create Certificate Request” and enter in the following information when requested into the “Distinguished Name Properties” pop-up window which appears and once completed click next and on the “Cryptographic Service Provider Properties” window select the “Microsoft RSA SChannel Cryptographic Provider” from the Cryptographic service provider and the Bit length of”2048″ from the dropdown lists. Then save the CSR on your desktop providing it with a name e.g XM_APNS-CSR.txt

IIS Request Your Response
Common Name e.g myMDM-for-xm-anps.axendatacentre.com
Organization
Organizational Unit
City/locality
State/province
Country/region

3: Next navigate to https://xenmobiletools.citrix.com/ from the IIS Windows server that you generated this XenMobile APNs CSR from and sign-in with your Citrix partner access details.
4: Upload your CSR as described on-screen at https://xenmobiletools.citrix.com/ which then return a *.plist file to download (Save it).
5: Next navigate to Apple’s Push Certificates Portal at – https://identity.apple.com/pushcert/ and login with your Apple ID. Next click “Create a Certificate” and upload your *.plist file that you downloaded from the XenMobile Tools portal as per step 4 above where instructed following the on-screen instructions. It will then prompt you to download a *.pem file ignore the filename e.g MDM_Zenprise.pem.
6: Import the *.pem file from the download APNs portal from step 5 above into IIS using the complete a CSR response and specific a friendly name (use the same common name you specified in step 2 above. Optional if your cert import fails the be sure to import Apples intermediate and root certificates from – http://www.apple.com/certificateauthority/ and repeat the import process once more. Also check out – http://support.apple.com/kb/ht5012 entitled “Lists of available trusted root certificates in iOS” for further help & guidance.
7: Export the imported APNs certificate via IIS and specify the path to save the cert which will be in *.pfx format and also specific a strong password to protect your APNs cert and finally note to self DO NOT FORGET the password.
8: When prompted during the XMS Admin WebUI configuration post completing the XMS CLI setup, follow the below import process in table format.

Import Keystore
Keystore Type PKCS #12
Use as APNs
Keystore file The path to your completed XM APNs cert which will be in *.pfx
Password The password you typed in at step 7 above

What is Framehawk?
It forms part of HDX Broadcast technologies within the High Definition eXperience (HDX) stack providing an enhanced X1 UX over broadband wireless, cellular connections where users experience the effects of packet loss, congestion, latency and jitter. The technology came from the Framehawk acquisition made by Citrix in 2014 ref – https://www.citrix.com/news/announcements/jan-2014/citrix-acquires-framehawk.html. Framehawk is defined as light weight frame buffer protocol (UDP based) and adds a new virtual channel to the ICA protocol. The initial release is targeted at users connected to XAD 7.6 FP2 via TRU networks however as of 14/08/2015 ref * Framehawk is now also available for users running the latest up to date iOS Receiver – http://blogs.citrix.com/2015/08/03/receiver-for-ios-6-0-now-available-with-framehawk-support/ utilising NetScaler Gateway 11.0 build 62.10 ref the following CTX blog which also includes details surrounding the initial Framehawk release within XAD 7.6 FP2 at – *http://blogs.citrix.com/2015/06/30/our-first-release-of-framehawk-technologies/.

New Use Cases for Framehawk
The following official Citrix blog articles provides insight into some of the use cases for Framehawk – http://blogs.citrix.com/2015/08/17/new-use-cases-for-framehawk/.

HDX Framehawk Performance in XenApp and XenDesktop 7.6 FP3

Demonstration of Citrix (HDX Broadcast now with Framehawk) vs. VMware

Pre-requisites & System Requirements for Deploying HDX Broadcast now with Framehawk (Draft + The Basic’s Only)
0: The HDX Broadcast now with Framehawk admin guide is available at – http://docs.citrix.com/content/dam/docs/en-us/xenapp-xendesktop/xenapp-xendesktop-7-6/downloads/Framehawk%20Administration%20Guide.pdf which I would strongly suggest that you read through before undertaking any type of PoC or internal testing of Framehawk’s capabilities within your own home lab, organisation demo environment.
1: You need to download the XAD 7.6 FP2 components from http://www.citrix.com/downloads.html. Also download and the firmware update for NetScaler Unified Gateway 11.0 build 62.10** to upgrade your NUG V/A.Note: The current supported Citrix Receivers (update 22/08/2015) are the Windows Receiver 4.3 or iOS Receiver 6.0.
2: Download the DisplayStateGUI.exe * tool from http://blogs.citrix.com/2015/08/17/got-framehawk-weve-got-remote-access-tips-and-tricks/ its a good read by way so be sure to read through that official CTX blog articles aswell prior to deploying Framehawk in your Home/Test lab or for a customer PoC.
3: In your Citrix test or home lab environments snapshot all the relevant XAD 7.6 infrastructure components that requires which an update which is most rior to proceeding. This is typically a common leading best practise so that you revert back in the unlikely event of a failure or corruption of any components during the infrastructure update.
4: Once the updates have been completed successfully installed and you’ve rebooted your compoments seperately in an agreed maintenance window the launch Citrix Studio upon a successful reboot and create a new policy selecting the Framehawk policies and adding them to your test user(s) or group(s). It is not recommended to apply this HDX policy to all users within your Site but only those whom are experiencing high packet loss ref page 12 of the Framehawk Admin Guide. Also be sure to carefully review and understand the provided technical overview of each policy setting by reading the policy description.TIP: Type in frame in the search window to find the Framehawk policies in Studio quicker.
5: Also make sure that your install and update the server, desktop VDA’s within your template images or create a new set of template(s) for your desktop and server OSes. It’s your choice :-).
6: I’d suggest that you utilise a Windows end-point for your initial tests of Framehawk, so navigate to http://receiver.citrix.com which should auto detect your Windows endpoint and recommend that you download and install Citrix Receiver 4.3 for your Windows OS.
7: Once the Windows Citrix Receiver 4.3 has successfully installed and configure Receiver to point to your Citrix test or home lab environment and begin testing :-). TIP: Why not setup a DNS SRV record for e-mail based discovery check out – http://docs.citrix.com/en-us/storefront/3/sf-plan/sf-plan-user-access.html.
8: Once your have configured Receiver a lunch a destkop and run DisplayStateGUI.exe * and also login into the new and update Director to check that your launch ICA/HDX session is in fact utilising using Framehawk and not DRC or the SuperCodec.
9: Once your happy proceed to snapshotting your NUG V/A and begin the firmware upgrade from your exsiting NUG build to the current supported firmware version which is 11.0 build 62.10**.
10: Once your have upgrade your NUG V/A and it is functioning as expected then proceed with the following to enable delivery of HDX Broadcast now with Framehawk via your NetScaler (Unfied) Gateway.
11: Enable DTLS in the settings of the VPN virtual server, enable and open 443 on TCP/UDP and unbind and rebind the SSL cert-key pair this second part is mandatory for more detail ref 16 of the Framehawk admin guide.
12: Deploy XAD 7.6 FP2 as your typically would utilising either the built-in wizards, manually using AppExpert e.t.c
13: Once its is successfully configured navigate to your external gateway FQDN and login to ensure that you can successfully authenticate and access your RfW powered by StoreFront 3.0 with the unified experience enabled ref – http://docs.citrix.com/en-us/storefront/3/sf-manage/sf-receiver.html. Now logout and return to the NUG Admin WebUI.
14: Now complete the following steps within the NUG Web AdminUI to enable and allow Framehawk ICA/HDX sessions through your NetScaler Unified Gateway V/A:

– Click configuration tab -> NS Gateway -> Virtual Servers now click “Edit” then click “More”
– Select to enable DTLS then click “Ok”
– Now within the VPN Server screen click e.g “1 Server Certificate”
– Write down the name of the certificate
– Select your server cert and the click on Unbind above from the list of menu options and then save/close
– You be returned to the VPN Server screen and there will be NO certs that is normal. Now click on “No Server Certificate” to reopen it
– Click on the + sign
– Find your certificate within the list and click “Select” then when prompted click “Bind”.
– Ignore and click OK on the warning error message entitled “No usable ciphers configured on the SSL vserver/serivce”

15: Begin testing using Windows Receiver 4.3 from any supported Windows end-point.
16: If you wanted to enable and allow Framehawk access from iOS devices running Receiver 6.0 then please complete the following:

– On your SFS access App_Data dir of your Store in C:\inetpub\wwwroot\Citrix\Store\App_Data\
– Open the file entitled default.ica
– Under the [WFClient] section within the file add the following line of code Framehawk=On which should be under ProxyUseFQDN=Off
– Click “Save”

17: Begin testing using Citrix Receiver iOS 6 on an iOS device.
18: If you have downloaded the initial Framehawk Admin Guide is doesn’t including the remote access setup and configuration so please re-download the admin guide at – http://blogs.citrix.com/2015/08/17/got-framehawk-weve-got-remote-access-tips-and-tricks/. It well worth a re-read in my view to better understand Framehawk.

SYN230: HDX update: What’s new
If you want to learn what’s new and all the updates to Citrix HDX i’d suggest that you watch the following Citrix Synergy 2015 session entitled “SYN230: HDX update: What’s new”.

Supported Citrix Receivers
1: The current supported Citrix Receivers for Framehawk are the Windows Receiver 4.3+ and the iOS Receiver.

Deployment Preparation Overview (DRAFT & MAY CONTAIN ERROR(S))
The following is an upgrade process that I utilise within my own home lab. Please ref to http://docs.citrix.com/en-us/netscaler/11/license-upgrade-downgrade/upgrade-downgrade-the-system-software.html for an accurate and official upgrade process.

1: Download the firmware of your choice if more than one is available at – http://www.citrix.com/downloads/netscaler-adc.html. Please note that your will require either a valid Citrix account to download the firmware.
2: Upload the *.tgz file you downloaded to the following location on your NS V/A “/var/install“. Once you have confirmed its successfully uploaded disconnect and close your (s)FTP application. I use WinSCP myself which can be downloaded at – https://winscp.net/ as my (s)FTP client.
3: Open a Secure Shell (SSH) connection to the NS V/A and enter in the username and password access details where prompted. Once your have successfully logged in type “shell” then type “cd /var/nsinstall” to change to the nsinstall directory and then type “ls” to confirm the uploaded file is there.
4: Now to unpack the tarball package by typing in “tar –xvzf build_X_XX.tgz”, where build_X_XX.tgz (TIP: Enter in B and press TAB to complete typing the name of the file) is the name of the NS firmware build that we will be upgrading to. Once the tarball is successfully unpacked type in “ls” verifying that you can see the extracted files from the tarball.
5: Now type in “./installns” to begin the upgrade process and where prompted type in “Y” to reboot the NS V/A
6: Move to your hypervisors mgmt. console and watch the NS CLI reboot and once you can see the NS login prompt within the CLI navigate to the NS mgmt. IP addr and login using your NS access details and verify that the NS V/A has been successfully upgrade to your firmware of choice by looking at the firmware version in the top right-hand corner of the WebUI.

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.

a – 1x Public routable FQDN for MDM e.g enroll.axendatacentre.com
b – 1x Public routable static IP addr that resolves to the MDM FQDN
c – 1x Public routable FQDN for MAM e.g apps.axendatacentre.com as Secure/Worx’s apps utilise a mVPN via WorxHome now SecureHub
d – 1x Public routable static IP addr that resolves to the public FQDN MAM
e – 1x DMZ private static IP addr for Gateway for your mVPN traffic
f – 1x DMZ private static IP addr for Load-balancing the MAM traffic
g – 1x DMZ private static IP addr for MDM traffic e.g enrolling and on-going device mgmt.
h – 1x DMZ private static IP addr for the actual XMS V/A

– 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.

ShareFile Restricted Zones

The views, opinions expressed are those by the author of this entry only.

What are ShareFile Restricted Zones?
Citrix ShareFile recently introduced a feature known as restricted zones which now allows CTX Mobility Admins (SysAdmins) with the ability to encrypt there ShareFile metadata with on-prem keys prior to uploading your On-Prem StorageZone (SZ) metadata to the ShareFile SaaS tier often referred to as the ShareFile Control Plane. Historically you could not encrypt your ShareFile metadata but you always been able to encrypt your ShareFile data within your On-Prem SZ as described at – http://support.citrix.com/proddocs/topic/sharefile-storagezones-31/sf-install-sz-controller.html.
ShareFile data is where your actual files and folders are stored e.g Word documents, Images, PowerPoint presentations etc. within your SZ. ShareFile metadata contains data about data (e.g user & file info) and read a full detailed overview on page 7 of the ShareFile security whitepaper available at – https://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/sharefile-enterprise-security-whitepaper.pdf. Finally it is very important to understand when you enable a restricted zone that only employee’s within your Active Directory (AD) are able to access this SZ and this feature is only available with on-prem customer managed ShareFile SZ.

System Requirements & Installation
You require StorageZones Controller 3.1 or higher which can be downloaded at – http://www.citrix.com/content/citrix/en_us/downloads/sharefile.html and a full list of the system requirements is available at – http://support.citrix.com/proddocs/topic/sharefile-storagezones-31/sf-storagezones-sys-reqs.html. Once you’ve downloaded the software then begin preparing Windows Server, networking & certificate requirements following these instruction’s detailed at – http://support.citrix.com/proddocs/topic/sharefile-storagezones-31/sf-install-storagezones.html/

Standard vs. Restricted Zones
It is important to understand that the traffic flows between a tradition standard and restricted SZ are different so be sure to spend time reviewing each diagram at – http://support.citrix.com/proddocs/topic/sharefile-storagezones-31/sf-deploy.html. It is also important to note that any/all e-mail notifications sent for a configured restricted zones are sent via your organisations local SMTP servers instead of the ShareFile SMTP servers.
