#App-V and #XenDesktop 7 – #Citrix, #AppV

A couple of good posts from Citrix (Ram Kumar Mantena & Nagendra Kumar) around the support for App-V on XenDesktop 7 and what to think of etc.

Tips/Tricks for Using App-V Integration with XenDesktop 7.0

XenDesktop 7.0 is released and it supports both Apps and Desktop Virtualization. One of the key features of this release is support for Microsoft App-V.  As this is the first release for App-V support, here are some tips/things to consider for an easy deployment of App-V 5.0 in a XenDesktop Environment.

  • XenDesktop 7.0 supports Server based App-V deployment scenario where Admin uses App-V Publishing Server and Management Server to manage apps.
  • Microsoft App-V client does not support more than 5 Publishing Servers. In Citrix Desktop Studio, although the admin can add one Management and one Publishing server through Studio UI, he can also add multiple Publishing Servers using low level SDKs. It is recommended to add only 5 Publishing Servers. Though Studio low level SDKs take more than five Publishing Servers, studio enumerates App-V apps from first 5 Publishing Servers.
  • When adding the Management Server and Publishing Server in App-V publishing node, if the test connection fails and App-V Server is up and running, make sure WinRm is up and running.
  • Once the Virtual Desktop Agent is installed on Server/Client, make sure CtxAppVCOMAdmin is member of Administrator group. This is required as some of the App-V operations on VDA side need administrator privileges. This is the user account pre-created by Citrix XenDesktop VDA installation. [CTX138057]
  • It is recommended to enable SharedContentStoreMode…. Read more…

How to check which #NetScaler policy that your #Citrix #Receiver or web browser hits?

April 18, 2013 1 comment

Ok, this is a common issue that you’ll end up in when setting up Access Gateway access scenarios:

How do you know which policy that is hit when your different Receivers are logging in?

Well, there are a couple of nice commands that can help you troubleshooting your access scenario! I guess that most of you have a simple scenario where you have one domain to authenticate against and some simple PNA, CVPN and potentially SSL VPN policies and profiles to deal with, and they are all linked to the virtual server like something like this simple example:

AG_vServer_VIP

But in more complex scenarios you may end up controlling which browser the user is accessing with (for giving nice error messages instead of Citrix default messages when users may use an unsupported browser etc.), or when you have multiple AD domains and AD groups to link different policies to etc. Then it may be complex and you have multiple policies and profiles for the same config with minor changes like the SSO domain name etc. So how do you then troubleshoot that easily?

First we have the must know command that hooks into the auth process of the NetScaler and gives you a view of the authentication process:

cat /tmp/aaad.debug

When you run that and you authenticate you’ll see the result of your auth process agains for instance LDAP and RADIUS sources like the result here when I logged in to our little environment:

aaad_debug_output

At the top of the output you see all the AD groups that I’m a member of that needs to match the group that you like to use on the NetScaler side, and last you see that accept from AD for my authentication request.

Then you know that you’re authentication ok, but which of the session polices are we hitting? Then you need to have a look at this great command:

nsconmsg -d current -g pol_hits

This is the output when I access using my Receiver on OS X:

nsconmsg_policy_hit

Get Started with #SharePoint Server 2013 Quickly on #Windows #Azure

Another good blog posts by Bill Baer (Microsoft) that shows how easy it is to try out SharePoint Server 2013 on Azure!

In order to remain competitive in today’s business climate you need to be able to respond to change and challenges quickly.  Sometimes that means adjusting your SharePoint infrastructure on a moment’s notice to maintain a competitive advantage.

Infrastructure as a Service solves these challenges through a ready-to-use, pay as you go solution which means you can deploy in hours as opposed to days, whether you’re looking to deploy a simple SharePoint-based Internet site or to quickly provision a development environment.

SharePoint 2013 on Windows Azure Virtual Machines enables you to rapidly deploy and host your business websites on a secure, scalable cloud infrastructure.

What are Windows Azure Virtual Machines?

Windows Azure Virtual Machines enable organizations to deploy custom Windows Server images to Windows Azure. Virtual Machines provide developers complete control of the application environment and allow easy migration of existing applications to the cloud. To learn more about Windows Azure Virtual Machines see also http://www.windowsazure.com/en-us/home/scenarios/virtual-machines/.

How can I benefit from Azure IaaS?

Demystifying Citrix Excalibur Architecture – via @kbaggerman

A great blog post by Kees Baggerman! 🙂

For all XenApp admins and consultants out there Project Avalon will bring a big change as we are used to having XenApp servers running on the (what seemed to be) everlasting Citrix Independent Management Architecture and we’re heading to Citrix FlexCast Management Architecture (already included in XenDesktop at this moment) and will be included in the Citrix Excalibur Architecture.

IMA

When looking up IMA in the eDocs you’ll find:

Independent Management Architecture (IMA) is the underlying architecture used in XenApp for configuring, monitoring, and operating all XenApp functions. The IMA data store stores all XenApp configurations.

Basically IMA exists to manage the XenApp or Presentation Server farms by enabling the communications between servers. As stated it transfers information about all XenApp functions like licenses, policies, sessions and server loads. All management tooling within these versions of Citrix’s PS/XA rely on this service for information.

According to Communication ports used by Citrix Technologies IMA uses the following ports:

Ports Source Prot. Comment
2512 Common Citrix Communication Ports TCP Independent Management Architecture (IMA)
2513 Access Gateway 5.0 Controller administration TCP IMA-based Communication

As we can see IMA uses 2512 (by default) to communicate with other servers and the Access Gateway Controller uses 2513 (by default) for IMA-based communication. The port IMA uses can be changed or queried via the commandline tool IMAPORT.

Brian Madden did a blogpost way back in 2007 but it’s definition of IMA is still current:

Independent Management Architecture is:

  • A data store, which is a database for storing MetaFrame XP server configuration information, such as published applications, total licenses, load balancing configuration, MetaFrame XP security rights, and printer configuration.
  • A protocol for transferring the ever-changing background information between MetaFrame XP servers, including server load, current users and connections, and licenses in use
FMA

With the introduction of XenDesktop we got a new architecture called Flexcast Management Architecture. This new architecture has got an agent-based setup where we can install the operating system including the basic applications that need to be installed and after that we can install an agent. This agent registers itself to a controller and is offered through StoreFront to the end user.

This will be delivered by two different types of agents, one to support Windows Server OS’s and one for Windows Desktop OS’s.

Andrew Wood did an article on Excalibur and used this diagram to explain the architecture:

Citrix FlexCast Management ArchitectureCitrix FlexCast Management Architecture

  • Receiver provides users with self-service access to published resources.
  • StoreFront authenticates users to site(s) hosting resources and manages stores of desktops and applications that users access – Web Interface as a platform is essentially resting, but it will cease to be.
  • Studio is a single management console that enables you to configure and manage your deployment, a dramatic reduction over the 23 consoles you could well have today. Studio provides various wizards to guide you through the process of setting up an environment, creating workloads to host applications and desktops, and assigning applications and desktops to users.
  • Delivery Controller distributes applications and desktops, manages user access, and optimizes…
