Heartbleed OpenSSL security and Citrix

April 17th, 2014 by Jack Cobben No comments »

large-hero-heartbleedAs alll of you know by now, and if you don’t you have been hiding under a very big rock, OpenSSL had a very big bug in it’s design which causes unwanted people to gain access to encrypted traffic.

As a Citrix employee I’ve been asked several times if and what products of Citrix are affected by this heartbleed security issue.

Well, this KB article is updated as needed and provides information on current Citrix products that are affected and what update you need to install. It also lists 3rd party updates on which Citrix relies on if they are affected.

Last but not least it lists a complete list of Citrix products that aren’t affected :).

Book review Citrix XenDesktop 7 cookbook

April 17th, 2014 by Jack Cobben No comments »

7463EN_Citrix Cover.jpgPackt publishing contacted me recently to review a new book they published on Citrix XenDesktop 7.

Gaspare A. Silvestri has written this book and does explain all the various settings and features of XenDesktop 7. Even if you aren’t experienced with this product he will guide you through this one and keep you interested in knowing more about this product.

As you all know I’m a great fan of using screenshot to enhance the readability of a document/post or book. Gaspare does this also in this book and it makes it easier to read and even helps you in where you can find certain settings.

If you don’t have this book yet, I would recommend it to add this to your bookshelf and read it.

Hope you find this review usefull.

Until the next book review or blogpost wlEmoticon-winkingsmile.png.

empty outlook folder pane after Windows updates

September 11th, 2013 by Jack Cobben No comments »

Like a good MS supporter (ahum) does is install the Windows Updates every month. last night I updated my Win 8 system with the latest patches and this morning I cam across this beautiful Outlook folder pane:

outlook pane

After uninstalling kb2810009 and kb2817630 the folder pane was back again.

Hopefully Microsoft will fix this bug soon….

Just my 2 cents for today.

How to Enable Continuous CDF Tracing in Provisioning Services 7.0

August 8th, 2013 by Jack Cobben No comments »

This article describes how to enable continuous CDF tracing in Provisioning Services 7.0.

Requirements

CDFMonitor

Background

With the introduction of Provisioning Services 7.0, the Provisioning Services logging mechanism has changed from persistent log files to CDF tracing. Provisioning Services no longer logs streaming event to a log file. You must configure CDF tracing to capture persistent logging for determining the root cause of a problem.

Procedure

To enable continuous CDF tracing in Provisioning Services 7.0, complete the following procedure:

  • Download the Provisioning Services specific configuration file from this article.
  • Extract the files to the C:\cdfmonitor folder.
  • Replace the CDFMonitor.exe.config that comes with CDFMonitor with the one downloaded from this article.
  • Open a command line interface and open the C:\cdfmonitor folder.
  • Run the following command:
    cdfmonitor.exe /installservice

    CDFMonitor runs as a service that persists even after the server restarts. Continuous CDF trace is then captured on all modules. The trace file will grow to 100 MB in size and will rotate between five files. The moment the CDFMonitor service is restarted, a new CDF trace file is created.

Download

You can read more instructions and download the special CDFMonitor.exe here.
