#Citrix #Receiver for Linux 13 released
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.

#Citrix #XenMobile 8.5 MAM upgrade! Part 1 – #StoreFront, #AppController, #NetScaler
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:
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…
#Citrix blog post – Get Up To Speed On #XenDesktop Bandwidth Requirements
Welcome to the HDX bandwidth testing blog series! In the following posts I’ll be sharing key findings and results from an extensive round of XenDesktop 5.6 / XenApp 6.5 bandwidth testing. Already using XenDesktop 7? Well then stay tuned for the last post in the series where I will be discussing that as well. Before I begin, I want to take this opportunity to thank Andy Baker and Thomas Berger for their tremendous help and guidance in managing this effort.
Part 1: The Prologue
It is not uncommon these days to have great LAN networks with what seems like unlimited bandwidth. I find myself at the office running multiple virtual desktops, uploading my files to ShareFile, all while streaming Spotify to my machine at the same time without even noticing. Even at home you have a nice fast connection just for yourself. Unfortunately many users do not have this luxury due to expensive business grade connections which are often over utilized. Overlooking this fact during a deployment can result in frozen and disconnected sessions and an overall poor user experience. This leaves IT departments frequently asking “how much bandwidth do I need for XenDesktop?”
Of course the answer to this question – in my opinion more so than most questions – is it depends. Why is that? Because it depends on what is on the screen at any given time. The amount of bandwidth consumed will be close to none when the session is idle, but can vary greatly depending on whether a user is typing, browsing a document, running a slideshow, or watching a video. Of course there is always the magic number of 20-30kbps that has been around forever, but that was before the explosion in multimedia content both on the web and now seen more frequently in applications as well . (Although I would note that we did reach and beat that 20-30kbps zone with some of our less multimedia intensive tests).
To help better answer this question our team decided to start running some tests…..a lot of tests. We measured general daily usage, took a deep dive into single application tests, and put some optimizations and best practices to the test. In part one of this blog I will be discussing the infrastructure and methodology for our first round of testing.
Infrastructure
The tests that I will be discussing were run in the environment shown below. A laptop was connected to anApposite WAN Emulator and used as the endpoint for both the manual and Login VSI tests. The emulator was used to control the bandwidth limits for each scenario that I describe later on in this blog post. The other end of the emulator was connected to a switch that was configured to send all packets in and out of the emulator to a mirrored port monitored by a server running Wireshark. This ensured all communication between the client and virtual desktop were captured without interfering with the VSI scripts. The environment infrastructure and desktop pool were also connected to the switch and communicated transparently to the laptop.
The environment was built using the product versions shown below. This is important to note as future tests are planned with XenDesktop 7 which benefits from newer codecs and algorithms for rendering. These tests were also run with the latest version of Login VSI which features more intense workloads than previous versions and a large randomized content library.
- XenServer 6.1
- Microsoft Server 2008 R2
- Windows 7 x86
- XenDesktop 5.6
- VDA 5.6.2
- Receiver 3.4 Enterprise
- Login VSI 4.0
Disclaimers
Before I begin to explain the tests that we ran I need to make a few disclaimers. The first being that quality of service (QoS) was not…

Remote Desktop Services are now allowed on #Windows #Azure – #RDS, #TS, #XenDesktop
This is a great thing that you should have a look at and investigate how it would fit you and your organization! Finally Microsoft has changed the license model! They still have some work to be done on it though so we can run Virtual Desktops (VDI’s) as well!! 😉
Read this great blog post from lpanzano:
I’ve not seen a lot of news about this so I thought it was worth writing a short post just to remember everyone that on July 1st, Microsoft has officially changed Windows Azure licensing terms (PUR) to allow the use of Remote Desktop Services (RDS) on Windows Azure Virtual Machines. Previously this scenario was not allowed in Windows Azure. Before July 1st you could only access an Azure Windows Server VM for purpose of server administration or maintenance (up to 2 simultaneous sessions are authorized for this service).
Let’s see some details about this change:
-
To enable more than 2 simultaneous sessions you will need to purchase RDS Subscriber Access Licenses (SALs) through the Microsoft Services Provider Licensing Agreement (SPLA) for each user or device that will access your solution on Windows Azure. SPLA is separate from an Azure agreement and is contracted through an authorized SPLA reseller. Click here for more information about SPLA benefits and requirements.
-
RDS Client Access Licenses (CALs) purchased from Microsoft VL programs such as EA, do not get license mobility to shared cloud platforms, hence they cannot be used on Azure.
-
Windows ‘Client’ OS (e.g. Windows 8) virtual desktops, or VDI deployments, will continue to not be allowed on Azure, because Windows client OS product use rights prohibit such use on multi-tenant/shared cloud environments.
-
Customers can use 3rd party application hosting products that require RDS sessions functionality (e.g. Citrix XenDesktop), subject to product use terms set by those 3rd party providers, and provided these products leverage only RDS session-hosting (Terminal Services) functionality. Note that RDS SALs are still required when using these 3rd party products.

Citrix also created a good blog post on their view of the top 5 scenarios for putting XenDesktop on Azure:
Top 5 Scenarios for XenDesktop on Windows Azure
Since Windows Azure launched I have looked forward to the day Citrix would be able to work jointly with Microsoft to support XenDesktop and XenApp workloads. We are excited that today is the day we announce support for XenDesktop 7 and XenApp 6.5 on Windows Azure. Customers can now take advantage of the leading Citrix desktop virtualization solution and all of the HDX user experience goodness on Microsoft’s leading public cloud. With the announcement we’ve published two design guides (here andhere) to help get you started with your deployments.
Upgrading to #Citrix #Receiver for #Windows – why and how?
This is something that all Citrix admins should read! How many questions don’t U get about which version of the client to use and why etc?
This document describes the various versions of Receivers for Windows, lists the reasons for upgrading, and recommends best practices for upgrading to the latest version of Receiver based on specific circumstances.
Note: The Online Plug-in 12.x will reach end of its maintenance in March 2013. Customers using Online Plug-in with XenApp 5, XenApp 6.x, XenDesktop 4.x, or XenDesktop 5.x must upgrade to the latest version of Receiver for Windows 3.X prior to that date where practical.
Citrix Receiver is the latest Citrix software you install on Windows end points to gain access to virtualized apps and desktops. It is also regularly installed on virtual desktops to enable access to virtualized apps.
The name of Citrix client software and the built-in functions are changed over the years. The clients in common use today are the Online Plug-in for Windows 12.X and the Receiver for Windows 3.X.
Where the Online Plug-in for Windows 12.X provided Web and PNAgent support, Receiver for Windows 3.X provides additional support. It can be configured for self-service access to applications, VPN-less remote access, single sign-on the Windows, Web, and SaaS applications, and has a built-in method to check for updates.
Both the Online Plug-in and Receiver have two versions.
- The Online Plug-in Web is used solely for Web access to applications and the Online Plug-in (Full) supports Web access as well as PNA Services. The Full version supported SSO, Smart Cards, and access to apps through the Start menu
The standard Receiver for Windows, CitrixReceiver.exe, can be considered is a complete replacement for the Online Plug-in Web and largely a replacement for the Online Plug-in (Full). It can be used for web access. It can be configured to access PNA Services. And it can also be used with the latest versions of StoreFront, CloudGateway (App Controller), and Access Gateway to provide a rich set of services. It contains the latest, multithread, multi-stream HDX engine.
It’s here! #Citrix #Receiver for Win 8/RT 1.2
The first official release for your touch-enabled Win RT tablet or Windows 8 Pro device now on the Windows Store! It adds the ability to connect to XenApp Services and XenDesktop Services sites for Web Interface deployments, not just StoreFront enabled sites. Connections can be direct or through Access Gateway Enterprise Edition. We also added the ability to open ica files if you’re using browser access. And we shouldn’t overlook the ability to save your password, if allowed by server policy.
This version will be useable in more configurations.
Click here to try this version. It is still a good idea to ask your IT department if it can be used in your environment. IT managers can find details on configurations supported and settings at Citrix eDocs.
Here is what it provides:
- Secure access to virtual desktops and enterprise apps
- Secure access to Web and SaaS apps (requires CloudGateway Enterprise)
- Work anywhere on any Windows 8 computer or tablet
- Account configuration using your email address, a server URL, or a provisioning file
- Auto-provisioned applications
- Use one published app at a time, along with multiple Web and SaaS apps
- Automatic display of the keyboard when needed
- Use of native controls for selecting an item from a list
- Option to save your Receiver password if allowed by server
And more functionality is coming
Look for updates every few months. Among other improvements, we’ve started work on multi-touch, audio, session sharing (support for multiple sessions)…

#Citrix VDI-in-a-Box 5.2, now supports CloudGateway etc. – @VDIinaBox, @CitrixCG
Ok, now VDI-in-a-Box is becoming more and more “complete”! This release delivers some of the features many have wanted for a while! For instance the support of the latest hypervisors as well as CloudGateway!
Read more below taken from the Citrix blog post:
Version V5.2 is now ready for prime time. The focus of this release was to support the latest hypervisors and Citrix components. Actually we did a lot more because we added a few features that our users have been clamoring for.
Support for the latest hypervisors:
As always we need to stay current and so version 5.2 supports vSphere 5.1, XenServer 6.1 and Microsoft Hyper-V Server 2012. The latter should increase desktop density quite a bit. We’d love to hear your experiences along those lines. Please post on the forum what sort of density increases you are experiencing.
Unified access to VDI-in-a-Box desktops and your applications and data:
Version 5.2 now supports Citrix’s Cloud Gateway and allows you to access VDI-in-a-Box through it. Cloud Gateway provides a unified application and data store allowing you to access Windows, web, SaaS and Mobile applications seamlessly and so we felt it important that VDI-in-a-Box work with this application and data aggregation service.
Real-time collaboration with Microsoft Lync:
In addition, we support Microsoft Lync via the Citrix HDX RealTime Optimization Pack for Microsoft Lync. Now users can seamlessly participate in audio-video or audio-only calls to and from other HDX RealtTime users and other standards-based video desktop and conference room systems. This is especially good for call centers and the like who want wide ranging soft phone functionality with their virtual desktops.
Highly available Personal Desktops with PVD:
Many had asked that we provide some form of high availability for Personal (PVD) desktops. We provide this by allowing you to place PVD desktops on shared storage. Here’s how it works. You specify a third datastore which resides on shared storage and VDI-in-a-Box will honor this request and store all Personal desktops using PVD on it.
Turn old desktops into locked down thin clients:
Kids will be kids and so many school lab administrators have asked that we provide a way to lock down the devices used in their labs. Now, you can download the Desktop Lock from the VDI-in-a-Box download page on the Citrix web site. It will allow you to lock down the physical device and essentially turn your old desktops and workstations into a thin client that connects directly to VDI-in-a-Box and keeps the kids from doing any mischief.
Fully automated software update with our Touchless DTagent:
And since we’re always looking for ways to make things simpler, with V5.2, we now have a fully automated way for you to upgrade the VDI-in-a-Box software. We had two issues in the past. First, you had to manually install the VDI-in-a-Box desktop agent on a golden image (that is then used to stamp out multiple desktop instances). Second, when you upgraded the VDI-in-a-Box software, you had to manually update the agent on each existing golden image. In Version 5.1, we automatically install the agent on all new images. With V5.2, we now provide you a list of existing golden images whose agents need to be updated and once you click yes, we walk you through a wizard to automatically upgrade the agent and test the golden image. For more details on this, see the blog by David Liu: http://blogs.citrix.com/2013/01/22/viab-5-2-makes-updating-desktop-agents-easier/.
