Fred Donovan from Citrix have updated the whitepaper – Communication Ports Used by Citrix Technologies to version 1.5 (April 2011)


This document provides an overview of ports that are used by Citrix components and must be considered as part of Virtual Computing architecture, especially if communication traffic traverses network components such as firewalls or proxy servers, where ports must be opened to ensure communication flow.


The assignments are listed by the Internet Assigned Numbers Authority (IANA), updated regularly, and revised when new information is available and new assignments are made. The specific location of the port numbers list is available at the following Web site:

How to Configure Dazzle for Use with XenApp/XenDesktop and Provisioning Services

Written by Thomas Poppelgaard. Posted in Dazzle, Reciever, XenApp, XenDesktop

I noticed an great Citrix article that Alexander Ervik Johnsen ( have pointed to: CTX124932, that i wanna share with you also but i have some thoughts i wanna add to it.

Citrix® Dazzle is the  first self-service “storefront” for enterprise applications. Dazzle  gives corporate employees 24×7 self-service access to a broad array of applications, desktops and content, allowing them to choose exactly what they need, when they need it.

My thoughts:
Citrix® Dazzle is the perfect match with Citrix XenApp & XenDesktop, the article was made, how to best practise implement Citrix® Dazzle in an XenDesktop enviroment. 

Citrix have made an article, how to “Configure XenApp for the Optimum Dazzle user Experience”,  but i think CTX124932 is also suitable  for configuring Dazzle with XenApp in a Citrix Provisioning Service environment.

Please note that Citrix Dazzle requires Citrix Reciever and the user behaviour is soon changed. 
Citrix release soon Citrix Merchandise 2.0 and Citrix Reciever 2.0, where its possible to distribute a Citrix Reciever without users have to be prompted, the current  Merchandise 1.2 and Citrix Reciever 1.2 requires the users to provide their credentials “first time”, Citrix have listen to the end customers and changed the behavior in the upcoming release.

Can any one let me know how soon is Citrix going to release the next version of 1y0-351 Exam for Netscaler IOS ver.11.

Hey Thomas,

nice article! I was wondering if you have a link to an official statement of Google (Chrome) about this change. I’m having the opposite experience with V45. Each time I start it, Hardware accelaration is used, except for Canvas, Multiple Raster Threads & Rasterization. I’m using it on a non GPU accelerated XenApp 6.5 farm on 2008 R2 OS.

Thanks in advance



CCU for Maxwell (M6/M60) not for Kepler (K1/K2)
+ SUMS = % Sotfware maintenance per year related CCU licenses

Pricing structure will reach new heights………..

I was surprised and confused by what NVIDIA now appears to be stating about needing NVIDIA CCU licenses to use GRID 2.0 M6/M60 instances. Seealso which implies that this licensing is needed above and beyond what licenses are needed from Citrix or VMware to access various features. Can someone perhaps provide better clarification? As far as I can tell, the GRID K1 and K2 units are exempt from this, so it would appear this is something new and specific to the M6/M60 models. If this is really true, the pricing structure could be a major factor in the decision to go with these newer models vs. the K1/K2 options.
