#XenMobile and the #Citrix Mobile Workspaces Architecture – #BYOD

This is a great blog post by Christopher Campbell and good picture to show the overall capabilities and architecture of the Citrix offering!

You’ve heard us talk about Mobile Workspaces and if you’re a techie you’re probably wondering if Citrix really has the architectural components (a complete, comprehensive and fully integrated architecture) that can deliver any app and data to any user on any device over any network?

Well let’s first identify a few of the market leading technologies that make up the Citrix Mobile Workspaces solution:

  • XenApp mobilizes and secures Windows apps on any device
  • XenDesktop securely delivers virtual Windows desktops and apps on any device
  • XenMobile manages and secures mobile, web and SaaS apps on mobile devices
  • GoToMeeting empowers people to meet and collaborate with anyone, anywhere
  • ShareFile shares and syncs corporate data securely from any location
  • NetScaler optimizes and secures app delivery and on any network
  • CloudPlatform orchestrates and provisions apps, desktops and IT services from any cloud

OK, OK. We know you have the products but do they really integrate?

Yes. Don’t believe me? Well as they say a picture is worth a thousand words. This is what the Mobile Workspace Architecture looks like.

OK. I get it.  You have the architecture but that doesn’t necessarily translate to a seamless user experience.

Still don’t believe huh? Well this is what the user experience looks like.

XenMobile is a key ingredient in delivering a mobile workspace.  Along with XenApp and XenDesktop it allows organizations to deliver on giving users access to any app from any device. In fact, if you’re an existing XenApp or XenDesktop customer, XenMobile seamlessly plugs into your existing architecture.

If you’re a XenDesktop or XenApp customer this is what your environment probably looks like.

Now this is what you need to enable EMM for BYO and COPE (Corporate Owned, Personally Enabled) devices and add that MDM, MAM, Secure Email, Secure Data…

Bug in Citrix Receiver 13 for Linux – cannot connect with multiple STAs – @CitrixSupport, @CitrixReceiver, #Citrix

Ok, we’ve had some issues with Citrix Receiver version 13 for Linux.. and it’s not just ONE issue. I found one that I thought I just have to share… so it’s lab Saturday for me at the office in a true geek manner with two XenClients and my favourite MacBook!

Bugg_finding_geek_Saturday

I guess that some of you have tried the Linux Receiver and knows how hard it is to get working, especially on a 64-bit distribution of Linux like Ubuntu 12.04 LTS och 13.10 LTS.

If you follow these instructions you can get it onto the device and then login through a browser (local Receiver UI may still not be full functioning!)..

https://help.ubuntu.com/community/CitrixICAClientHowTo

What I’m about to show you is that it’s not just only getting Receiver on the device and ensuring that the SSL certificates are trusted. You then have to be able to use it as well externally through a NetScaler Gateway (NSG) into StoreFront and your XenApp/XenDesktop VDA’s.

Just assume that you have a production environment that consists of a NetScaler Gateway and a StoreFront server, if you then in StoreFront have configured your NetScaler Gateway correctly and the appropriate STA configuration (with MULTIPLE STA’s) then you will notice that you can’t launch a session.

BTW, the recommendation from Citrix is to use multiple STA’s, right! See this from edocs:

For all deployments, if you are making resources provided by XenDesktop, XenApp, or VDI-in-a-Box available in the store, list on the Secure Ticket Authority (STA) page URLs for servers running the STA. Add URLs for multiple STAs to enable fault tolerance, listing the servers in order of priority to set the failover sequence. If you configured a grid-wide virtual IP address for your VDI-in-a-Box deployment, you need only specify this address to enable fault tolerance.

Important: VDI-in-a-Box STA URLs must be entered in the form https://serveraddress/dt/sta in the Add Secure Ticket Authority URL dialog box, where serveraddress is the FQDN or IP address of the VDI-in-a-Box server, or the grid-wide virtual IP address.

The STA is hosted on XenDesktop, XenApp, and VDI-in-a-Box servers and issues session tickets in response to connection requests. These session tickets form the basis of authentication and authorization for access to XenDesktop, XenApp, and VDI-in-a-Box resources.

If you want XenDesktop, XenApp, and VDI-in-a-Box to keep disconnected sessions open while Citrix Receiver attempts to reconnect automatically, select theEnable session reliability check box. If you configured multiple STAs and want to ensure that session reliability is always available, select the Request tickets from two STAs, where available check box. Read more…

#Netscaler Insight and Integration with #XenDesktop Director – via @msandbu

November 15, 2013 Leave a comment

Great blog post by Marius! 🙂

This is another one of Citrix hidden gems, Netscaler Insight. This product has been available from Citrix some time now, but with the latest update in became alot more useful. Insight is an virtual applance from Citrix which gathers AppFlow data and statistics from Netscaler to show performance data, kinda like old Edgesight. (NOTE: In order to use this functionality against Netscaler it requires atleast Netscaler Enterprise or Platinum)

Insight has two specific functions, called Web Insight and HDX insight.
Web Insight shows traffic related to web-traffic, for instance how many users, what ip-adresses, what kind of content etc. 
HDX Insight is related to Access Gateway functionality of Citrix to show for instance how many users have accessed the solution, what kind of applications have they used, what kind of latency did the clients have to the netscaler etc.

You can download this VPX from mycitrix under Netscaler downloads, important to note as of now it is only supported on Vmware and XenServer (They haven’t mentioned any support coming for Hyper-V but I’m guessing its coming.

The setup is pretty simple like a regular Netscaler we need to define an IP-address and subnet mask (Note that the VPX does not require an license since it will only gather data from Netscaler appliances that have a platform license and it does not work on regular Netscaler gateways)

After we have setup the Insight VPX we can access it via web-gui, the username and password here is the same as Netscaler nsroot & nsroot

image

After this is setup we need to enable the insight features, we can start by setting up HDX insight, here we need to define a expression that allows all Gateway traffic to be gathered. 
Here we just need to enable VPN equals true. We can also add mulitple Netscalers here, if you have a cluster or HA setup we need to add both nodes.

image

After we have added the node, just choose configure on the node and choose VPN from the list and choose expression true.

#Citrix #Receiver for Linux 13 released

November 13, 2013 Leave a comment

Finally Citrix has released a Receiver version for Linux that for instance has StoreFront support! Can’t wait to try it out and see if it gives the same user  experience etc like the one on OS X and Windows!

Here you have some details about it and links to the product documentation:

Access Windows applications and virtual desktops, as well as web and SaaS applications. Enable anywhere access from your Linux thin client/desktop or use web access.

What’s new

The following new features are available in this release:

  • Support for XenDesktop 7 features – Receiver supports many of the new features and enhancements in XenDesktop 7, including Windows Media client-side content fetching, HDX 3D Pro, HDX RealTime webcam compression, Server-rendered Rich Graphics, and IPv6 support.
    Note: Link-local network addresses are not supported in IPv6 environments. You must have at least one global or unique-local address assigned to your network interface.
  • VDI-in-a-Box support – You can use Receiver to connect to virtual desktops created with Citrix VDI-in-a-Box.
  • Self-service UI – A new graphical user interface (UI), like that in other Citrix Receivers, replaces the configuration manager, wfcmgr. After they are set up with an account, users can subscribe to desktops and applications, and then start them.
  • Deprecated and removed utilities – The pnabrowse command-line utility is deprecated in favor of the new storebrowse command-line utility. The icabrowse and wfcmgr utilities have been removed.
  • StoreFront support – You can now connect to StoreFront stores as well as Citrix XenApp sites (also known as Program Neighborhood Agent sites).
  • UDP audio support – Most audio features are transported using the ICA stream and are secured in the same way as other ICA traffic. User Datagram Protocol (UDP) Audio uses a separate, unsecured, transport mechanism, but is more consistent when the network is busy. UDP Audio is primarily designed for Voice over IP (VoIP) connections and requires that audio traffic is of medium quality (that is Speex wideband) and unencrypted.
  • Packaging – An armhf (hard float) Debian package and tarball are now included in the download packages. In addition, the Debian package for Intel systems uses multiarch (a Debian feature) for installations on 32- and 64-bit systems. 32-bit binaries are also available in RPM packages.
  • System Flow Control – Video display has been enhanced on low-performance user devices that connect to high-performance servers. In such setups, System Flow Control prevents sessions becoming uncontrollable and unusable.
  • Localization – Receiver is now available in German, Spanish, French, Japanese, and Simplified Chinese.
  • Keyboard improvements – You can now specify which local key combination (Ctrl+Alt+End or Ctrl+Alt+Enter) generates the Ctrl+Alt+Delete combination on a remote Windows desktop. In addition, a new option supports Croatian keyboard layouts.
  • Deferred XSync – While one frame is still on screen, Receiver can now decode tiles for the next frame. This provides a performance improvement compared with previous releases, in which Receiver waited for a frame to finish being displayed before decoding the next frame.
  • Audio and webcam playback improvements – Various changes are implemented that conserve CPU cycles and reduce latency.
  • Audio settings – Several new audio settings are now available in module.ini.

How to: #Citrix #XenMobile 8.5 MAM upgrade! Part 2 – #StoreFront, #AppController, #NetScaler

September 9, 2013 1 comment

Hi again!

If you haven’t read Part 1 then I highly recommend doing so prior to going directly to the upgrade that we’re covering in this post!

Prepare for a journey in this post about Citrix StoreFront upgrade, uninstallation, console and how messy it could be! NOT all the time, sometimes it “just works”! 😉

My little NetScaler is already upgraded to 10.1 so unfortunately I couldn’t take you on that journey as well, so we’ll start with the StoreFront upgrade from 1.2 to 2.0 in this post. These are the steps that we need to cover as highlighted in the migration guide that seems very short and straight forward:

Upgrade StoreFront 1.2 to 2.0.

  1. Logon to the StoreFront server console.
  2. Upgrade StoreFront by running the StoreFront 2.0 installer as an administrator.
  3. When the upgrade is completed, open StoreFront administration snap-in, remove CloudGateway controller from each store as this will be moved in the migration solution.
  4. Open NetScaler Gateway Properties and for each gateway defined and change the version field in settings from 9.x to 10.0.x or later.
  5. Test the configuration by logging on through web browser or Citrix Receiver.
  6. Verify if the users are able to login and authenticate to StoreFront defined stores configured.

Is it this easy?

Ok, I’ve downloaded the 2.0 installer, and I’m logged on to the server.

Before we even start the upgrade there are things that could go wrong in removal or upgrades of StoreFront. And one that I’ve seen cause a lot of headache for a lot of people out there is that they have the Windows Firewall service disabled. Though the installation and removal wants to delete or add these rules the installation will fail unless this service is running. As you can see in this picture below you see the FW rule added in StoreFront 1.2:

Windows_FW_Rules_SF1

So let’s verify that the Windows FW service is started, and it is!

Windows_FW_SVC_started

I’ll now start the installation by double-clicking the StoreFront 2.0 installer!

StoreFront_2_0_Installer

What is this popup that came directly after starting the installer?

Receiver_HTML5_popup_installation

Wait, ok so you guys at Citrix couldn’t ask me whether you could do this for me? My plan is to upgrade, so please just add a little step in your upgrade program that does this for me… change request #1 for the next SF release and it’s upgrade process! Verify pre-requisites or deal with them!

#Citrix #XenMobile 8.5 MAM upgrade! Part 1 – #StoreFront, #AppController, #NetScaler

September 1, 2013 7 comments

In this little blog series series you’ll follow a little upgrade process to XenMobile 8.5 for Mobile Application Management (previously known as CloudGateway).

Ok, I don’t exactly know where to begin. I must first say that Citrix is THE master when it comes to renaming products, updating/changing the architecture, changing consoles (claiming to reducing the number of them like every year but at the same time introduce new ones).

How hard can it be to make crystal clear documentation and upgrade processes that works and are easy? I feel already that my tone in this blog post is “a bit” negative… but I think that Citrix actually deserves it this time.

I must now take a step back and calm down and point out that Citrix is delivering some MAJOR changes and good news/features in the new XenMobile 8.5 release though! It’s great (when you’ve got it up and running) and I must say that I don’t see anyone that is near them in delivering all these capabilities in a nice end-to-end  delivery!! 🙂

Have a look at everything that is new, deployment scenarios etc. here before you even start thinking to upgrade or change your current NetScaler, StoreFront and AppController environment!

Once you’ve started to read the different design scenarios you’ll see that App Controller can be placed in front of StoreFront, in the back of StoreFront or totally without StoreFront… all the options just make your head spin! Because Citrix doesn’t really make it clear on how all of this should work with a Receiver and Worx Home depending if the device is on the internal network, external through NetScaler or what the capabilities that you need are supported in the different scenarios in a simple way, just text that explains it. And I find the pictures and text a bit misleading:

You can include StoreFront in your deployment, which allows users access to published applications from XenApp and virtual desktops from XenDesktop, along with apps configured in App Controller. When users log on with Citrix Receiver, all of their apps appear in the store. The following figure shows how you can deploy NetScaler Gateway, App Controller, and StoreFront in your network.

Deploying App Controller with StoreFront and NetScaler Gateway

As you see above the App Controller is added as a “Farm” just as in 2.6, but is that the truth now in version 2.8 of App Controller?

If you have a look at the text from this page it’s getting even more confusing: Read more…
