See how Citrix XenDesktop for Linux looks – #Citrix, #XenDesktop, #Linux, #EnvokeIT, #BYOD, #DaaS

June 4, 2015 1 comment

This is one of the coolest things a part from the Workspace Cloud service that Citrix is working on. I’ve had the pleassure of trying this out and we at EnvokeIT have been doing a lot of tests of this Linux VDA tech preview.

Isn’t it great that both Microsoft and Citrix now seem to love Linux 🙂   (and yes, I manipulated these images so it’s not an official Citrix statement!)Richard_happy_when_Microsoft_and_Citrix_Loves_Linux

So this little blog post is just going to show of the capabilities and how nicely this integrates with the Citrix XenDesktop architecture. First of all I’d like to say thanks to my colleagues Björn Bekkouche and Peter Smali for letting me use their lab environment!

Before we get into showing how it works and looks I must just highlight that if you have any questions about how we can assist you to deliver Linux-based Terminal Servers or VDI’s to remote users in a secure and optimal just contact us at EnvokeIT here or pop me an email: richard at envokeit.com.

This is great for all of you with Developers on Linux! Have them code from anywhere in a secure manner! They can run their Linux VDA in your datacenter, connect to it from an Receiver compliant device and code from them and you have your intellectual property secured internally instead of having them checking out Git repositories to their local devices etc.!

So what is XenDesktop for Linux? Well, to answer that really simple I assume that you have some basic knowledge of the Citrix XenDesktop architecture.. if you don’t then please read up on that a little before continue reading, one really good contribution to bulding your architecture is described in this Citrix Virtual Desktop Handbook or this Citrix XenDesktop – Blueprint. These contains a lot of valuable information that you shall think of and how to configure the environment to fulfill you use cases.

But overall think of the XenDesktop architecture of something like the following pictures (click to enlarge them). The first one shows the new model where we could run and take care of the VDA’s ourselves on-premise but leverage the Workspace Cloud service from Citrix so that we don’t anymore have to bother about the XenDesktop infrastructure components and the life-cycle management etc. of those. The second one is the more overall traditional architecture overview that you’d see of the different layers.

Apps-Service-Overview

XenDesktop_overview_architecture

And as you see above this details the standard architecture wher you would have your Server or Desktop VDA’s in the resource layer hosting the desktops for your users to connect to, but they have all been Windows-based up until now!

Now with the Tech Preview we can actually install the Linux-based VDA on a Red Hat or Suse machine and access that through the SAME Delivery Controllers and StoreFront stores that also manage our Windows-based VDA’s.

And this is awesome! 🙂 We can leverage the already existing Windows-based architecture to just “hook in” our Linux-desktops as well and get users to conect through Receiver for Web, Receiver and even through the NetScalers if you need (works like a charm!!).

So as you can see here we have a nice little landing page for our entry points that are running different versions and access different environments etc.

Synergy 2015 – A condensed recap of everything you need to know – via @gkuruvilla, #Citrix, #CitrixSynergy

This is a great summary recap that George Kuruvill has done of Citrix Synergy 2015! Great work and enjoy this blog post!

For those of you who were not able to attend Citrix Synergy this year & dont have the time to sit through the key note recordings, I decided to put together a condensed version of some of the key announcements. So here goes!

Citrix Workspace Cloud

  • Citrix hosted control plane that enables customers to deliver a comprehensive mobile workspace to end users.
  • Gives customers the flexibility to host workloads on premises, in public or private clouds.
  • Control plane also provides end to end monitoring of user connections.
  • Evergreen infrastructure since Citrix maintains all core infrastructure components.
  • Workspace Cloud Connector installed on premises on a Win 2k12 server that establishes SSL communication between control plane and customer environment. Used to talk to infrastructure components like Active Directory and hypervisors hosting workload

I wrote a blog on CWC and the value proposition a month back that you can find here.

SYN 217 –  Workspace Cloud – Technical Overview [Video]

 

Citrix Lifecycle Management

  • Comprehensive cloud based service that can be used to design, deploy and manage both Citrix and other enterprise applications.
  • Based on the ScaleXtreme technology.
  • Lifecycle Management enables customers/partners to deploy infrastructure not only on premises but also public/private clouds (resource locations)
  • Customers/Partners have the ability to create blueprints to automate infrastructure deployments end to end. Examples of blueprints include a XD deployment for instance where you could not only install all the XD infrastructure but also automate the installation of all supporting infrastructure like Active Directory, SQL etc.
  • Vendors have the ability to create blueprints as well that can then be consumed by customers and partners alike.
  • Customers/Partners also have the ability to incorporate scripts (new/existing) into the deployment.
  • Once a blueprint is developed, its added to a library. Any resource within the library can then be deployed to a resource location (on premises, public/private cloud)
  • Another key benefit of the Lifecycle Management technology is the ability to automate application upgrades.

XenApp/XenDesktop

  • Xenapp 6.5 maintenance extended till end of 2017, EOL extended till 06/2018. Details here
  • New Feature Pack for XA 6.5 (enhance storage performance, Lync support enhancements, UPM enhancements, Director “Help Desk” troubleshooting”, Storefront 3.0, Receiver.next)
  • XenApp/XenDesktop 7.6 FP2  (End of Q2)
    • New Receiver X1
    • Lync 2013 on Mac
    • Touch ID Support
    • HDX with Framehawk
    • Native Receiver for Linux
    • Linux Apps and Desktops (Redhat and SUSE support)
    • Desktop Player for Mac 2.0 (June)
    • Desktop Player for Windows (Tech Preview)

#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…

How to: Create Desktop Appliance site on StoreFront – #Citrix, #StoreFront, #ThinClient

February 3, 2014 4 comments

I guess that some of you out there by now are using Thin Clients and some are using Desktop Appliance site functionality in the old Web Interface for these thin clients that are XenApp- or XenDesktop-ready.

So now you have or are thinking on how to setup this on StoreFront!

Citrix has A LOT of work to do in order to ensure that StoreFront becomes a stable and enterprise ready! There are so many tweaks and configurations needed in config files etc. that just isn’t ok! Add them into the console! It’s not hard, even I could code in some menus, forms windows and trigger the underlying PowerShell scripts!

But back to the topic, how do we configure Desktop Appliance site in StoreFront? Well, first we need to have a look at the following edocs articles that explain how to do it:

Desktop Appliance sites – And the most important in this article is the bottom that details WHAT DOESN’T WORK!

Important considerations

Desktop Appliance sites are intended for local users on the internal network accessing desktops from non-domain-joined desktop appliances. When you decide whether to use Desktop Appliance sites to provide users with access to your stores, consider the following restrictions.

  • If you plan to deploy domain-joined desktop appliances and repurposed PCs, do not configure them to access stores through Desktop Appliance sites. Instead, configure Citrix Receiver with the XenApp Services URL for the store. For more information, see XenApp Services URLs.
  • Desktop Appliance sites do not support connections from remote users outside the corporate network. Users logging on to NetScaler Gateway cannot access Desktop Appliance sites.

How do you release this and don’t support connecting through a NetScaler Gateway? Then you miss the whole point of SmartAccess, you cannot trigger EPA (host checks) for instance to control ICA/HDX features like drive mapping etc. internally. And you cannot have thin clients on the Internet that connects into the enterprise through NetScaler Gateway! 

Next you should read this article that details the PowerShell madness 😉

Configure Desktop Appliance sites

I won’t go into details of the article above but rather show you how it’s done and with some examples of arguments to pass to the PowerShell scripts.

Step one is to log on to your StoreFront server, and just to show you our current setup is that we have one Receiver for Web (RfW) sites used for browser access into StoreFront:

Receiver_for_Web_site

From a Store perspective you can see that we have one (1) store that the RfW site exposes:

#Citrix #StoreFront subscription database replication, #GSLB, #NetScaler

January 13, 2014 Leave a comment

Ok, so we’ve all started to use StoreFront (or have U?) and find out that there are A LOT of things that you have to do in order to get it to work as you most probably want it to.

This post is more around how you ensure that the StoreFront architecture supports an enterprise with multiple sites while still having a concistent end-user experience.

Just imagine that you’ve built your architecture out in a true high availability manner with global server load balancing across all products used in the stack to deliver your Windows apps and desktops to your end-users. It may look something similar to this:

overall_storefront_nsg_GSLB_architecture

In this view you can see that we’ve setup GSLB to ensure that external (Internet) connected users  and devices are being connected to a NetScaler Gateway vServer in either London or Miami, and from there the NetScaler and the session profile that communicates with StoreFront (SF1 and 2 in each site) is also load balanced using GSLB to ensure high availability. So everything seems good, right! But no… consider that you as an end-user is being connected to the Miami site and that StoreFront group that has a subscription database containing all the apps and desktops etc. that you have selected and added to your workspace.  You will see all these icons by default now when you login to Miami, but you will not see them in the case Miami goes down for some reason or if you travel to London and then gets connected to that StoreFront group as I try to show by this picture:

#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.
