Power Switching a RaspberryPi

The Iconbar - Sat, 04/28/2018 - 09:27
Chris Hall has been trying to make the most of power for a RISC OS based RaspberryPi for his GPS system. In his guest post , he lifts the lid on how he does this...

A Raspberry Pi can be powered by a mains adapter or by a powerbank. I found myself often pulling out the power plug to power cycle the Pi and came up with a software power switching method that would allow power to be removed under software control.

A 'power booster' board allows an internal 3.7V Lithium-Polymer battery to produce a 5.2V output and any external 5V power source will take over this rule and charge the internal battery until fully charged. Switching on and off is controlled by an 'ENABLE' input, pulled high by default. A blue LED lights if power is being supplied to the computer. With the booster board output disabled, only a minimal current is drawn from the internal battery. A red LED lights if the internal battery becomes discharged below 3V (and if a diode is fitted to the 'LBO' pad this can disable the output automatically). Fully discharging the internal battery is likely to damage it.

While the internal battery is being charged a yellow LED lights, turning green when it is fully charged. A small current drain to light the green LED to show a full charge seems enough to keep some power banks happy even whilst the unit is otherwise powered down and the internal battery fully charged.

This means the external source can be connected and disconnected without affecting the operation of the device except to extend battery life.

Power control
With no power control hardware it is difficult to ensure that the computer is not, inadvertently,turned off during a write operation to the SD card, which can corrupt the file or the whole card. My power control circuit allows power to be applied at any time by pressing the 'on' button. The 'off' button simply signals that a power off has been requested, which can be detected in software. A shutdown/restart cycle will then remove power as soon as the system has been shut down and the CMOS updated.

If software detects a 'power off' request then all it has to do (once it has completed any essential tasks) is to issue the command:

SYS "TaskManager_Shutdown",162

which will do a shutdown/restart cycle.

Doing a manual shutdown (CTRL-SHIFT-f12) and then pressing 'Restart' will also remove power (if a 'power off' request has been issued).

How Does It Work?

Software can detect the 'on' button being pressed or held down by reading the GPIO 19 line and can use this information for any purpose. The fact that the 'off' button has been pressed (and the 'on' button remains open circuit) can be detected by reading GPIO 26, meaning that 'power off' has been requested.

A little piece of software in !Boot.Choices.Boot.PreDesk sets GPIO 4 to output high (which ensures power stays on even after a 'power off' request).

During a restart cycle, before any writes are made to the SD card, the ROM modules are reset which takes GPIO 4 to high impedance: with a 'power off' request pending this will remove power.

Provided that the unit has been operating for at least six seconds (enough time for the RISC OS desktop to start), the 'off' button will pull GPIO 26 low but do nothing else. Software can detect this, complete any essential tasks and then either explicitly set GPIO 4 low (if a Witty Pi is present, this will remove power immediately) or (if not) perform a complete system shutdown using the command SYS "TaskManager_Shutdown",162 which will shutdown all applications tidily and restart RISC OS. The effect of this is to update the CMOS êlast time onë setting and restart the ROM. As the ROM reinitialises, GPIO 4 becomes high impedance thus removing power.

The 'on' button has some additional functions: whilst pressed, components (R6, R7 and LED) may also be fitted to present an LED load to any external power source that will only light if the external source is healthy (this works by sensing whether Vs from the power boost board is 3.7V or 5.2V). If a voltmeter is fitted as shown, the voltage of the internal LiPo battery is displayed whilst the button is depressed. A power meter can also be connected between the power boost board and the Raspberry Pi giving a voltage, current and power consumption readout.

Battery Life
With an internal 4400mAh LiPo battery, a Raspberry Pi Zero with an OLED display and GPS module (but with no HDMI connection) uses about 170mA (at 5V) and the battery should therefore last for about (4400 x 3.7)/(170 x 5.2)h which is just over 18 hours. A 5000mAh 5V powerbank should extend this by about 28 hours.

Migrating local VM owner certificates for VMs with vTPM

Microsoft Virtualisation Blog - Thu, 12/14/2017 - 06:27

Whenever I want to replace or reinstall a system which is used to run virtual machines with a virtual trusted platform module (vTPM), I’ve been facing a challenge: For hosts that are not part of a guarded fabric, the new system does need to be authorized to run the VM.
Some time ago, I wrote a blog post focused on running VMs with a vTPM on additional hosts, but the approach highlighted there does not solve everything when the original host is decommissioned. The VMs can be started on the new host, but without the original owner certificates, you cannot change the list of allowed guardians anymore.

This blog post shows a way to export the information needed from the source host and import it on a destination host. Please note that this technique only works for local mode and not for a host that is part of a guarded fabric. You can check whether your host runs in local mode by running Get-HgsClientConfiguration. The property Mode should list Local as a value.

Exporting the default owner from the source host

The following script exports the necessary information of the default owner (“UntrustedGuardian“) on a host that is configured using local mode. When running the script on the source host, two certificates are exported: a signing certificate and an encryption certificate.

Importing the UntrustedGuardian on the new host

On the destination host, the following snippet creates a new guardian using the certificates that have been exported in the previous step.

Please note that importing the “UntrustedGuardian” on the new host has to be done before creating new VMs with a vTPM on this host — otherwise a new guardian with the same name will already be present and the creation with the PowerShell snippet above will fail.

With these two steps, you should be able to migrate all the necessary bits to keep your VMs with vTPM running in your dev/test environment. This approach can also be used to back up your owner certificates, depending on how these certificates have been created.

DHCP – Activate Filter “Allow” & import MAC address from SCCM by WMI request

Archy.net - Tue, 08/29/2017 - 12:08

Hello folks,
Recently, i have post a script to interroge SCCM and find the MAC address informations. In this post, i show you how activate DHCP Filter “Allow” to protect your DHCP delivery lease to deny access to your network (i know, there is NAP or NAC but, it is a simple way to block the issuance of a DHCP lease).

Prerequirements

First, you need to create a Active Directory user and give to this account rights “DHCP Administrator”.

In SCCM console, add this users to group “Read-only Analyst” .

Activate filter “Allow” on DHCP server

Connect to your DHCP Server and open the management consoleOn the IPV4 tab, open the drop-down menu, and then select the “Filters” option and right-click the “Allow” folder and select “Enable”.

From now, the DHCP server no longer delivers leases.

On the DHCP Server, launch this script for retreive and add the MAC Address informations from SCCM Server to filter list “Allow”.

Source code   # Connection information $SiteName = "FR1" $ServerSite = "sccm" # WMI Request $ImportSCCM = $(Get-WmiObject -Class SMS_R_SYSTEM -Namespace "root\sms\site_$SiteName" -computerName $ServerSite) # Create collection $Mycoll = @() foreach ($obj in $ImportSCCM) { Write-Host $obj.NetbiosName $obj.MACAddresses $obj.OperatingSystemNameandVersion $Mydetails = "" | Select-Object PCName, MacAddress, OS If ($([String]$obj.MACAddresses) -eq "") { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = "Nul" $Mydetails.OS = $obj.OperatingSystemNameandVersion } Else { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = [String]$obj.MACAddresses -replace ":","-" $Mydetails.OS = $obj.OperatingSystemNameandVersion } $Mycoll += $Mydetails } #Add MacAddress into DHCP Filter foreach ($objects in $Mycoll) { Add-DhcpServerv4Filter -List Allow -MacAddress $objects.MacAddress -Description $objects.PCName -Confirm:$false -Force -Verbose } # Remove Obsolete entries Compare-Object $(($Mycoll | Select-Object MacAddress).MacAddress) $(Get-DhcpServerv4Filter -ComputerName $DHCPServer -List Allow | Select-Object MacAddress).MacAddress -IncludeEqual | % { if ($_.SideIndicator -eq "=>") { Remove-DhcpServerv4Filter -ComputerName $DHCPServer -MacAddress $_.InputObject -Confirm:$false -Verbose } }

When the script is finished, you can see into the management console of DHCP Server, the entries are add into the “Allow” list.

The DHCP server correctly delivers the lease of the device whose MAC Address is allowed.

SCCM – Find Devices MAC Address

Archy.net - Fri, 08/25/2017 - 12:56

Hello Folks,

This week I needed to export from SCCM, the devices name and MAC Address to a CSV file.

I need this file to create green list into DHCP server. The Green list give permission to have a lease from DHCP server. I will speak of this subject in a futur post.

To find informations on devices into SCCM, we can work with WMI Class of SCCM. This script is based on WMI request.

Source code   $SiteName = "FR1" $ServerSite = "sccm" $Mycoll = @() foreach ($obj in (Get-WmiObject -Class SMS_R_SYSTEM -Namespace "root\sms\site_$SiteName" -computerName $ServerSite)) { Write-Host $obj.NetbiosName $obj.MACAddresses $obj.OperatingSystemNameandVersion $Mydetails = "" | Select-Object PCName, MacAddress, OS If ($([String]$obj.MACAddresses) -eq "") { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = "Nul" $Mydetails.OS = $obj.OperatingSystemNameandVersion } Else { $Mydetails.PCName = $obj.NetbiosName $Mydetails.MacAddress = [String]$obj.MACAddresses $Mydetails.OS = $obj.OperatingSystemNameandVersion } $Mycoll += $Mydetails } $Mycoll | Out-GridView

XenApp 6.5…incoming!

Paul Lowther - Fri, 02/17/2012 - 23:05

Hey folks,

I know it’s been a while and I’m still getting visits to the site.  A lot of the information I posted here is still valid, so thanks for your continued visitations.

I’m just about to embark on getting XenApp 6.5 put into our environment, based on Windows 2008 R2 (of course).  Whereas I won’t be doing the direct engineering myself, I’ll be heading up the team doing it (stuff happens, people move on) but I’ll be able to bring you information as it comes in.

So, keep tuned in.

What’s more we’re looking to do a sizeable implementation of XenDesktop on XenServer too, so I’ll be sure to update you on some of that too.

If you have any requests, let me know – I’ll be sure to try to get the info!

Citrix Receiver and Juniper SSLVPN

Paul Lowther - Sat, 10/02/2010 - 18:25

What do you do if you have a requirement to have your Citrix Farm(s) available outside of the company firewall. ‘Available’ meaning usable on any device, become truly device agnostic!

You could punch some holes through your firewall and hope it meets the stringent company security regulations.

You could buy a Citrix Netscaler solution and use their in-built Access Gateway functionality to ‘easily’ allow ICA traffic into your network.

But…What if your company had already invested in SSLVPN technology and couldn’t justify Netscaler?

The answer, if you chose Juniper, which many companies do due to it’s standing in the technology space and magic quadrant position with Gartner and Forrester, is actually all rather simple.

On September 8th, Juniper released their new Junos Pulse app for iOS4.1 and above. This means that any device currently compatible with iOS4.1 can utilize an SSL connection through the Juniper devices, into a secure company network. Once the connection is established, you can fire up Citrix Receiver, put in your simple connection string for your farm and hey presto, access to your published applications and desktops on XenApp and XenDesktop.

OK, so we’re not device agnostic yet, but…

iOS4.2 is out in November, which will be release for the iPad, a big game changer for mobile computing due to it’s portability and screen real estate (self confessed fanboy!), which will mean Junos Pulse will work immediately, once installed and connected to your SSLVPN device.

For the non-Apple devices, I have it on good authority that Droid, Symbian, Windows Mobile and Blackberry are all in Beta development at the moment and will be released ‘soon’. Great news…and a step towards device agnostic usage, so long as there is a Citrix Receiver for your platform too.

Getting it to work:

Installing the app is as simple as any app from the App Store, configuring it is also pretty simple, what’s more, with the Apple iPhone Configuration Tool for OSX/Windows v3.1, you can create pre-configured connections for your device, which does the ‘hard’ work for your end users!

Configuring the Juniper SSL device is fairly simple too, as long as you are using the NetworkConnect, function your device will have access, albeit fairly pervasive, to the network you’re connecting to.

What do I recommend you do is:

Set up a separate realm for mobile devices, which you specify as the connection string
Create a new sign-in page that is friendly to small screens – check out the Juniper knowledge base for a sample download.
Limit the devices you want to have connect by specifying the client device identifier.
Limit the sign-in screen to be available to the *Junos* browser only.
Add black lists of network locations you don’t want everyone to have access to. These could be highly confidential data repositories or your ‘crown jewels’.
Add white lists of citrix servers you want your folks to have access to while on the network, or if you’re happy that the blacklist is sufficient, allow * for a more seamless and agile implementation which will not need adjustment as your farm grows.

There is a lot of flexibility in the solution and depending on your security needs you can mix and match some of these ideas and more in what constitutes a valid policy for your company. The more controls you add, the more you may need to revisit the configuration as devices arrive and requirements change.

Once you are up and running with NetworkConnect you can configure your Citrix Receiver client, connect and start using your Citrix apps strait away.

I was impressed how quick it was to achieve and painless the process has been made.

I don’t work for Juniper and have only recently become familiar with the technology but in my mind, Junos Pulse is a complete breath of fresh air. In forthcoming releases there will be host checkers and cache cleaners etc to ensure the device is adequately secure before allowing connection.

The area of mobile security is still in it’s infancy, it will be interesting to see if Juniper keeps up with the requirements for more security, or my hope is be the lead for others to follow!

Citrix Merchandising Server 1.2 on VMWare ESX (vSphere)

Paul Lowther - Sun, 03/21/2010 - 10:49

I recently acquired (yesterday) the Tech Preview version of Mechandising Server 1.2 from Citrix, which is specifically packaged for use on VMWare ESX.

Version 1.2 has been out or a short while, and whereas I had it running rather well on a XenServer, my company is a VMWare-only place right now, so getting this into a Production state would have meant jumping through several hoops.  I attempted to convert the Xen package over to VMWare but consistently got issues with the XML data in the OVF.

The new VMWare packaged file, which is around 450Mb, imported without a hitch!  Now I’m up and running on the platform of choice and this should make it easier for me to use in Production!  Good news!

Citrix recommends 2CPUs and 4Gb Ram for the instance.  Depending on your scale of usage, you can get it up and running with 1CPU and 1Gb RAM but that really does depend on how large your Directory data is.  For testing, I recommend 2Gb RAM, although it’s simple to adjust when you are more familiar with the load that is required for your environment.

If I find any gotchas with the configuration or getting Receiver/Plug-ins working with the Web Interface, I’ll let you know!

Thanks for reading, leave a comment!

AppSense 8.0 SP3 CCA Unattended

Paul Lowther - Fri, 03/19/2010 - 14:03

If you’re wanting an unattended installation of you AppSense CCA (Client Communications Agent) you will want to look here.

This is documented in the Admin Guide but I missed it on my first run-through.

The installation is the same for the 32-bit or 64-bit version, simply call the right MSI for your server type.  This is also true for the compatible Operating System versions, there’s only one per architecture but covers all compatible OS, which keeps it relatively simple.

Installation Script @echo off REM *** SETTING UP THE ENVIRONMENT NET USE M: "\\server\share\folder" /pers:no SET INSTALLDIR=M:\ REM **** Installing the AppSense Communications Agent (WatchDog agent installed also!) REM **** Set this VARIABLE for your own (primary) Management Server SET APPSENSESITE=SERVERNAME ECHO Installing AppSense Communications Agent.. cd /d %INSTALLDIR%\AppSenseCCA SET OPTIONS=INSTALLDIR="D:\Program Files\AppSense\Management Center\Communications Agent\" SET OPTIONS=%OPTIONS% WEB_SITE="http://%APPSENSESITE%:80/" SET OPTIONS=%OPTIONS% WATCHDOGAGENTDIR="D:\Program Files\AppSense\Management Center\Watchdog Agent\" SET OPTIONS=%OPTIONS% GROUP_NAME="ZeroPayload" SET OPTIONS=%OPTIONS% REBOOT=REALLYSUPPRESS /qb- /l*v c:\setup\log\cca.log START /WAIT MSIEXEC /i ClientCommunicationsAgent32.msi %OPTIONS%

This will install the CCA, set the installation folders, choose your “preferred” Management Server and then add it to a Deployment Group.

Management Console Considerations

One requirement for the Deployment Group is that it set for “Allow CCAs to self-register with this group”

This is set in the Management Console, in the group you have created, called ZeroPayload here, under the Settings section.  Putting a tick in the box is sufficient to complete the registration setting.

Now, a server will be able to join the group with the above unattended script.

What I have done, to manage how and when the agents and pacakages are deployed, is set the “Installation Schedule” to be set to “At Computer Startup – Agents are installed only when computers are started“.  I have added all the agents into this group but no PACKAGE payloads.  If you now reboot the server at your convenience, once the CCA is installed (in my case part of a wider XenApp install) the server will install the agents and immediately REBOOT the server one more time, since you need to remember that the Performance Manager agent will automatically issue a reboot request upon installation.

If you were to set this as “Immediate” in the Installation Schedule, there would be no control over when your server reboots.  Many people fall foul of that nuance of PM as it’s easy to forget (I’m sure the guys at AppsSense forget that on occasion too!).

One very cool behaviour is that you can add both 32-bit and 64-bit agents into this Deployment Group and your server will only install the version it needs for the given architecture.

So now your server is configured and ready for it’s final deployment.  If you’re like me and have  number of active Deployment Groups, some with a slightly different package payload, you can use this method initially, then move your server to the required deployment group.  If all agent versions are the same, and in the beginning they certainly should be, all that will be deployed when you move to another group is the Packages, and these don’t force a reboot.

One last thing to consider.  Any Environment Manager packages that have “Computer” settings will not be invoked until the next reboot.

So… there you have it in a nutshell.

Leave me a comment if you have experiences to share.

XenApp PowerShell Command Pack CTP3

Paul Lowther - Fri, 03/19/2010 - 09:09

I’ve recently started looking at PowerShell 2.o and bought the “for dummies” book to get me started.  My immediate need for usage of PowerShell was to automate some XenApp farm configurations.  This is where the XenApp Command Pack CTP3 comes into the picture.

Installation:

A pre-requisite, in addition to installing the following two components, is to install .Net Framework 3.5SP1 – this is specific to the XenApp Command Pack and use of CTP3 functionality.

NOTE: Anywhere a  is shown, this is not intended as line break merely a line continuation to overcome the shortcomings in WordPress!

ECHO+ ECHO Installing Windows Management Framework Core (including PowerShell 2.0).. start /wait WindowsServer2003-KB968930-x86-ENG.exe ♦ /quiet /log:c:\setup\log\WMF-PS.log /norestart ECHO Installing XenApp PowerShell Commands.. cd /d "%INSTALLDIR%\Citrix Presentation Server" start /wait msiexec /i Citrix.XenApp.Commands.Install_x86.msi ♦ INSTALLDIR="D:\Program Files\Citrix\XenApp Commands" ♦ /norestart /qb /l*v c:\setup\log\xa-cmds.log

Now I have the Commands installed, it’s relatively simple for me to manipulate the farm in any way I want! As far as I can see, anything that is configurable within the AMC (XenApp 5.0 FP2) can be manipulated with a PowerShell command. This includes both farm settings and server settings. I’ve also been able to set Server Groups, Server Console published icons, Administrator Access, Lesser-mortal-being Access (defined access rights) and more besides.

I would have added some of my code here but there are some sensitive items in it and would have to rewrite a lot just to display it.  It’s quite simple to get some quick results, believe me!

It’s a given that Citrix will increase their use of PowerShell in versions to come, such as FP3 and XenApp 6 for W2K8-R2. This for me can only be seen as a positive move!

I can’t recommend this one highly enough.  Check it out.

AppSense 8.0 SP3 Unattended Installation

Paul Lowther - Fri, 03/19/2010 - 08:18

It’s been a long time in coming but I finally got round to getting some progress with AppSense 8.0 @ work.

I don’t do anything unless I can automate it, so here’s my take on the unattended method for AppSense v8.0, in this case the files I used were SP3.  There is some great information in the documentation for the pre-requisites needed to get the software installed.  This is the condensed and automated sequence.  I recommend you read the documentation too!  One thing that is missing is how to do an unattended installation, which is where I felt it necessary to share my knowledge with you!

A word of warning, this isn’t as end-to-end as I’d hoped.  The pre-requisites and MSI installations are all you need to get the product running on your server but you still have to configure the product with the relevant databases for Management Server, Statistics Server and Personalisation Server, if you are using them.  I did manage to do a lot more with AppSense 7, like defining the database schema to use and setting the admin account to use etc, but I’ve since lost my snippets for v7 (an over zealous colleague being “tidy” on our code file server) and couldn’t find any settings within the MSI that looked like they would be relevant, so it’s install-then-configure this time!

My script here starts off with a server that already has IIS installed, but didn’t have BITS installed, so SYSOCMGR was used to add BITS.  If you’re installing IIS from scratch, ensure you add this component!

The IIS-BITS.inf file is simply:

[Components] BITSServerExtensionsISAPI = ON NOTE:  Anywhere I added the  symbol, it’s not intended as a line break!  I’m just overcoming the shortcomings in WordPress for long lines of continuous text. @echo off REM *** SETTING UP THE ENVIRONMENT NET USE M: "\\server\share\folder" /pers:no IF NOT EXIST M:\ GOTO FAULT SET INSTALLDIR=M:\ REM ** Enable BITS for IIS ECHO Enabling BITS for IIS START /WAIT sysocmgr.exe /i:%systemroot%\inf\sysoc.inf /u: ♦ "%INSTALLDIR%\AppSense\32-bit\IIS-BITS.inf" /r /x REM *** Installing Dot Net 3.5 ECHO .Net Framework 3.5.. cd /d "%INSTALLDIR%\32bit.kit\DotNet35" START /WAIT dotNetFx35sp1.exe /Q /PASSIVE /NORESTART REM *** Installing Visual C++ Runtime 2005 SP1 (needed for hotfixes etc) ECHO Visual C++ Runtime 2005 SP1.. cd /d "%INSTALLDIR%\32bit.kit\vcredist.2005.sp1" START /WAIT vcredist_x86.exe /q:a /c:"VCREDI~3.EXE ♦ /q:a /c:""msiexec /i vcredist.msi /qn"" " REM *** Install MS XML6 Runtime ECHO MSXML6.. cd /d "%INSTALLDIR%\AppSense\32-bit" START /WAIT msiexec /i msxml6.msi REBOOT=ReallySuppress ♦ /qb- /l*v "c:\setup\log\msxml6.log" REM *** Installing AppSense Components cd /d "%INSTALLDIR%\AppSense\32-bit" ECHO Installing 32-bit AppSense Management Server component..

For the .Net Framework file, don’t go looking for dotNetFx35sp1.exe, since this is merely the download of 3.5SP1 renamed so it doesn’t look like standard 3.5, and was done for my own future sanity if nothing more.

.Net Framework 3.0 is the minimum requirement but I’m aligning all my current work on 3.5SP1 since I may wish to use PowerShell 2.0 as and when possible.  I certainly did for XenApp with favourable results (will post about that later).

Post Installation work:

Once the software is installed, you need to connect to or create the databases you’ll need for your choice of functionality you’re going to make active.

Click Start -> All Programs -> AppSense -> Management Center -> AppSense Management Server Configuration

Go through the GUI, tell it where your blank (but already created) schema resides, present it with some credentials and you’re set!

The only other step you *may* be faced with is that the configuration tool analyses the installation to see if there any anomalies.  These are termed as variances in the GUI.  For me, since I’m logged in as an Administrator anyway, I ask the GUI to repair all variances, in all locations.  Once done, the installation is complete.  The steps are very similar for the Statistics Server and Personalisation Server.  It is recommended (for larger installations) that you put Personalisation on it’s own server instance, but Management Server and Statistics Server can occupy the same instance.

I’m planning on installing the CCA with the XenApp base build, so I will likely post that unattended install next.

Leave a comment, thanks for reading.

Citrix Merchandising Server 1.2

Paul Lowther - Fri, 03/19/2010 - 06:53

I’ve been experimenting with Merchandising Server recently.  Primary objective: To see what all the fuss is about.  How will this make my life (or at least the support team @ work)’s life easier?

Well on first look, it’s all looking rather good!  Here’s why:

  • Delivery of the Receiver software to any compatible device (Windows & Mac)
  • Delivery of Plugins (ICA aka Online/Offline Plugin, EdgeSight, Dazzle, EasyCall, etc)
  • Seamless Updating of new plugin versions (all fully customisable with rules for when to do or when to not do an action)

I can see our rather large user base (35k ICA installs and counting) being quite taken by the fact that they don’t have to seek out a “scripted” install to replace what they already have, we can do the “hard work” for them – and roll it back if a new version sucks (you know it happens occasionally!)

So what’s the catch:

Well since I am bound by the rules that *essentially* we are a VMWare shop at my place of employment, the Merchandising Server is a VM Appliance that is only available for those running XenServer.  This is a big disappointment.  Do you guys realise how many hoops I’d have to jump through to get a XenServer (or two) installed in Production.  Not only that but I’d have to write the documentation to support it, in addition to documenting the Merchandising Server, not a prospect I relish.

Look Citrix we know XenServer is a good product – and it’s free for simple implementations – but it’s not really “enterprise” thinking when you limit the use of a product like this.

But “WAIT”, I hear you say…breaking news…

The good folks at Citrix, in their infinite (albeit slightly tardy) wisdom have done the “enterprise” thing!  Whilst browsing around myCitrix.com today, I noticed that they have just released a VMWare instance!  Now that is good news.

I do have a slight challenge though, my subscription level seems to be limiting my ability to acquire said item.  Fear not, I tell myself, I have an email sat in my Citrix Account Manager’s inbox, asking for assistance of the intervention kind!  If/when I get it, I’ll post about it.  If the step-by-step documentation sucks, I may even write that up too.

If you have client sprawl in your Citrix jurisdiction, I really do recommend you check out the Merchandising Server, it could pave the way for an integrated solution for the future!

Today’s entry is brought to you by the letters J, P and G.

Sesame Street is 40 today and Google is paying homage by changing it’s image to commemorate this momentus day!

I know I spent many an hour clocked in front of the TV watching big bird and the gang…
