• In my previous blog about Login PI3 I showed how to install and configure Login PI 3. In this blog I will show you how to create new applications in Login PI 3 and will show you how to add basic steps for that application. In this article I will use SumatraPDF (because it is my favorite PDF viewer) as an example, you can replace SumtraPDF with your own application as wanted.

  • On the sixth of November 2018 Login VSI introduced the Release of Login PI 3. In this blog I will take you with me during my exploration of this new version of Login PI. Version 3 of Login PI is been designed and built from scratch. The need for a windows server to run the application on is gone. Login PI 3 is based on an appliance. To be able to run the appliance you will need ESX 5.

  • My colleague Arno Meijroos was at a customer where they were experiencing disconnects when using Citrix Receiver 4.6. When the customer used Receiver 4.5 no disconnects occured. NetScaler was running on Firmware version An MPX was used. Whilst looking at trace files on NetScaler and Client side all that was noticable was that the connection was terminated on the NetScaler side. On the NetScaler custom cipher suites were defined to get an A+ rating in SSL Labs.

  • Recenlty I have been involved at a customer where we deployed a new NetScaler pair with the latest and greatest firmware version. We ran into an issue with certificates. In this blog I will talk about the issues we ran into and how you can solve them. When running NetScaler firmware and you want to install a PFX certificate there is a possibility that you receive the following error (No certificates present in the certificate bundle file):
  • While I was working on a side project I found the need to have some kind of logging while using my Spoof User Profile program. I did some code editing and now the new version of the Spoof User Profile program uses logging when switching the state key(s). The path of logging is made configurable, in two ways: By using a environment variable SPOOF: By using a parameter /LOC= The /LOC takes precedence over the evironment variable.

  • In a previous blog I wrote about adding a footer to the NetScaler gateway. Since that post Citrix included the RfWebUI theme Citrix has posted a support article how to add a footer to this theme. Specifically from that article the following piece of code is extracted add rewrite action rw_act_insert_loginfooter_2 insert_after_all "HTTP.RES.BODY(120000).SET_TEXT_MODE(IGNORECASE)" q{"(\"<div style='text-align:center;color:white;font-size:15px;'>Experiencing technical difficulties?<br>Open the"+" <a style='color:white;text-decoration:underline' href='http://citrix.com'>Citrix Guide</a> or Report an issue to the"+" <a style='color:white;text-decoration:underline' href='mailto:xyz@citrix.

  • I recently was involved in an assignment which involved upgrading Immidio Flex+ to VMware UEM. This upgrade is fairly simple, but can be pretty annoying for end-users, where an upgrade may impact their user experience. First of all, I will try to explain what group policy extensions are and what they do. Group Policy extensions are extension (well duh) of the standard Microsoft Group Policy objects. They rely on the group policy service, have their own .

  • Recently I have been involved at a customer where we did the NetScaler Gateway implementation. Our good practise is to make sure that we lease the internet accessible IP’s with atleast an A rating in SSL Labs. At the customer I was involved a Pentest was conducted. The pentest was pretty thourough (as expected) and came with a few recommandations. A few of the recommandations related to the HTTP header the NetScaler sends back.

  • I was aiding a co-worker with some profile management stuff in a PoC he was doing on Windows 10 and Server 2016. Pointed him out to Workplace and Profiles. He got going with it implemented everything and came back to me with the remark that everything works, but they have a second state key in the registry that has a backup tack between brackets (see picture) As you can see there is a State [Backup] entry existant in the registry, this also needs to be set to the correct value.

  • This week I was at a customer to help them with a NetScaler upgrade. The customer was on a 10.5 firmware and wanted (had to) upgrade to 11.1. So far no problem there.. They have a NetScaler Acces Gateway license, no problem either.. They wanted customization on the Gateway portal, hey no problem. They wanted some links and text on the gateway portal, no problem. Uuuh problem! After upgrading the secondary appliance, failing it over and applying the rewrite rules, nothing appeared on the Gateway portal.
