Technical Advisories

vCenter Server Internal Certificate Expiration – If your vCenter server (Appliance or Windows) was deployed as 6.5 Update 2 or later, the Security Token Service (STS) signing certificate may have a 2-year validity period.  Depending on when your vCenter was deployed, this may be approaching that expiration date.  There is no vCenter Alarm for this condition.  I highly recommend you take a few minutes and check your environment and proactively replace the certificate if needed.

  • KB 76719: Scripted/automated method to replace STS certificate

Horizon View 7.12 Console login failure with Windows Server Core

Recently I started working with a new customer who is migrating to VMware Horizon View.  It has been a while since I have done much with Horizon so I thought setting it up in my lab would help me get up to speed.

I decided to install Horizon 7.12, setup a few desktop pools and learn about Instant Clones with an eye to upgrading to Horizon 8 (aka Horizon 2006 as it prefers to be known) in the near future.  I had been using Windows Server 2012 in my lab as those were the latest licenses I was able to get from my Microsoft Technet subscription before they ended that program.  Horizon 2006 does not support Windows Server 2012 so I had to make an early choice.  Do I run 2012 now, and upgrade it later or jump to a newer version now?

Lab Headaches can turn into knowledge

I decided to try Windows 2016 Server Core for my connection server.  I have always been pretty comfortable at command line; and wanted to try out Windows Server Core.  I have to admit it was a bit “different”  not have any of the familiar  GUI interfaces.    Some of the smallest things (ahem configuring network stack) took me a bit and forced me to learn something new.  This is a good thing – and why it is a good idea to get in the lab often.

vToolbelt – February 2020

Welcome to (hopefully) the tail end of winter! A few brief glimpses of sun has me hopeful that the dreary days are behind us!

There is a lot of VMware Virtualization news to cover this month.  Some important changes are noted in the Highlights section

Highlights for the Month

vSphere 6.0 & vCenter Server 6.0 will be at End of General Support on March 12th, 2020. Note:  Even if your hosts won’t support a later version of vSphere, if they are on at least 6.0, you can still update vCenter Server to 6.5 or 6.7

Microsoft changes to LDAP Binding Requirements may impact vCenter Server and App Volumes
Apparently Microsoft will be changing how AD handles LDAP requests in their March 2020 updates.  Any LDAP requests that are not using TLS could be negatively impacted. The tech marketing team for vCenter has written an article on how these changes to MS LDAP Channel Binding & Signing could affect vCenter.

There are 3 protocols that will bind vCenter to Active Directory for authentication:

  • Unencrypted LDAP (LDAP:\\)
  • LDAP encrypted with TLS (LDAPS:\\)
  • Integrated Windows Authentication (IWA)

According to VMware testing, TLS\LDAPS and Integrated Windows Authentication binding methods are not impacted by this change.    I have received customer feedback that the MS tool that helps report on unencrypted LDAP requests is including applications that are using IWA bindings.

It appears App Volumes could be impacted as well.  There is a KB article (KB 77093) that discusses what VMware is working on for this and what you can do about it.

Upcoming changes to VMware CPU-based licensing
Beginning April 2nd, 2020, Any VMware software that is licensed on a per-CPU basis will require 1 CPU license for up to 32 physical cores.  If a CPU has more than 32 physical cores than an additional CPU license will be required.  You can read the full VMware CPU Licensing Change Announcement, as well as check out KB 77098, which describes how you can count the CPU cores in your environment (either using the vCenter Client or a PowerShell script).

Adobe Flash is near End of Life
Adobe has announced that they will EOL Flash at the end of 2020.  This likely means that browser manufacturers will stop supporting Flash-based apps in their browsers at some point this year.  (The Adobe article has links to the major browser partners and their plans)

The vSphere Web Client included with vCenter Server 6.7 releases (beginning in April 2018) have full HTML5 feature parity and no longer require Flash.  If you haven’t upgraded yet, now is the time to start planning.    A few things to check before you upgrade:

  • Host Compatibility – The hosts don’t have to run the same version as vCenter.  There is a interoperability matrix to show compatible versions.  Hint: vSphere 6.0 & Later
  • Software Compatibility – make sure any solutions that integrate with vCenter are supported.  VMware has a searchable Product Interoperability Matrix for products like Horizon, vRealize, etc.   You should also check any third-party solutions (backup, reporting, etc)
  • vCenter Client Plugins – If you use a client plugin to manage your SAN, A/V, etc you should also check with that vendor to make sure it is supported.

Where did the 1500 byte MTU come from anyway

I manage to stumble across a large number of bits of curiosity while researching technology topics.   Some of these make me scratch my head wondering how I never heard of it before.  I thought i would write some of them down.  Welcome to TechBITs!

These days, we just plug in a patch cable into our server and the machine gets on the network and off to work.  For the most part it isn’t a big deal.    I wish I could say I fondly recall the days of stripping the end of a coax cable to get a workstation on the Thinnet.  While I do remember it – fond is not a word I would use of that memory.

If you have worked in systems administration or networking for any length of time, you should at least be familiar with the standard 1500 byte MTU.  Do you know How the 1500 bytes became the MTU of the Internet?

vToolbelt – January 2020

I hope everyone had a Happy New Year!  2020 is off to a rapid start.  I continue to write 2019 as the date (per usual).

Product Support Highlight

  • A number of core vSphere products are nearing the end of General Support (particularly vSphere 6.0 & vCenter Server 6.0 in March).  You can find out the exact date in the Product Watch section.
