VMware Virtual Machines MAC addresses

  • simon 

VMware Virtual Machines MAC addresses Occasionally I feel old, today was one of those days.  The feeling snuck up on me during a conversation about MAC addresses. Someone mentioned a MAC address starting 00:50:56 and I said with confidence that it was a VMware virtual machine, which prompted the response “how do you know that?”.  Which leads us to the topic of this blog post, how did I know that? MAC addresses are not random. … Read More »VMware Virtual Machines MAC addresses

Interrogating data using modern applications

Following on from the VMware licence change announcements, detailed here.  I thought I’d take a quick look at the accompanying PowerShell module to see what the output looks like and what we can do with data that it gathers. The VMware KB for the PowerShell module includes details on how to import and usage.  You may however come across an error when you try and import the module due to digital signatures, much like the… Read More »Extending – Counting CPU licenses needed under new VMware licensing policy

Extending Simple Network Mapping – TCP Port Descriptions

  • simon 

Simple Network Mapping In an earlier post I demonstrated how you could use a very simple toolset such as VMware tools and Netstat to create visualisations for what devices are talking to each other on a network.  I had a few thoughts of my own on some additional simple steps that could be taken to improve the data and visualisation still further. A few conversations on Twitter and LinkedIn, convinced me to pull them together… Read More »Extending Simple Network Mapping – TCP Port Descriptions

Simple Network Mapping using VMware tools and Netstat

  • simon 

Network Mapping I had fun working out a simple way to extend application discovery using VMware tools,  following a retweet or two (or 17) it seems like a lot of folks enjoyed reading about it too.  So fresh from putting together a simple method to interrogate application data, helped by some very clever engineering from the VMware tools team and the function from William Lam, I thought I’d write up how we can reuse the… Read More »Simple Network Mapping using VMware tools and Netstat
