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…

Manage #Linux based clients in #SCCM 2012 R2 – via @ncbrady

Another great post from Niall C. Brady, keep up the great job!

Wouldn’t it be great to have a complete solution from Microsoft that handles all the configuration capabilities of most enterprise OS’s like Windows, Linux distributions as well as Mac OS X? Microsoft are at least doing a great job working towards a more complete offering!

Introduction

System Center 2012 R2 Configuration Manager supports a wide variety of operating systems including alternative operating systems such as the following:- 

Mac Client:

  • Mac OS X 10.6 (Snow Leopard)
  • Mac OS X 10.7 (Lion)
  • Mac OS X 10.8 (Mountain Lion)

UNIX/Linux Client:

  • AIX Version 7.1, 6.1, 5.3
  • Solaris Version 11, 10, 9
  • HP-UX Version 11iv2 , 11iv3
  • RHEL Version 6 , 5, 4
  • SLES Version 11, 10, 9
  • CentOS Version 6, 5
  • Debian Version 6, 5
  • Ubuntu Version 12.4 LTS, 10.4 LTS
  • Oracle Linux 6, 5

In this post I will show you how to install the Linux client on a popular Linux operating system (Centos 6.4) and do some basic actions like hardware and software inventory in System Center 2012 R2 Configuration Manager. This guide assumes you have already installed your Linux server and are ready for the next step. If you have not installed it yet just download the Live CD from here and boot from it, choose the option to Install to hard drive once the os has booted to the desktop.

Step 1. Download the Alternative Client files

When you started the System Center 2012 R2 Configuration Manager installation you probably didn’t notice that there was a link to download alternative clients on the splash screen highlighted in the screenshot below

If you did click on the link it would bring you here so go ahead and download those client files.

Step 2. Extract the Linux client files on a Windows computer

On the computer you downloaded the alternative client files, locate the Linux client exe file and extract the contents somewhere local by double clicking on the ConfigMgr Clients for Linux.exe file.

#Ubuntu for phones – backed by #Canonical

I must say that this is really cool and looks great!!

iOS is there as a stable platform that companies can rely on in terms of that SW development on this platform for native apps are great due to that Apple provides both the HW and the SW and therefore simplifies build of apps, you don’t have to make like 150 versions for all the device types out there that you need if you’re developing native apps for Android that uses complex features of the device. I guess the same scenario will come true for Ubuntu unless they only ship it with a small range of devices and keep the focus on true HTML5 apps as long as it fulfills the need…

I wonder how and when Canonical or others will take this Ubuntu platform on and bring it to market on a broad scale…. Anyway it looks very promising!

Read more here and go through the great feature set and design!
