A feature that was introduced in vSphere 7 is the ability to use pcap (tcpdump) filters with pktcap-uw. One of the use cases where this can be useful is filtering for TCP control bits.
In this post I wanted to draw your attention to a couple of Docker images I created. I found that while increasingly automating more aspects of my homelab deployment I needed a place to execute my code. And running this on my laptop isn’t always the best choice.
Have you ever found yourself wondering when a certain ESXi server was installed? In this case VMware GSS has your back. Check out KB 2144905 to find a simple esxcli command that dissects the hosts UUID to give you the installation date of that specific host. But what if you want to audit an entire cluster? This is where Powershell can help you out.
Lately I’ve been interacting a lot with REST APIs. I found that testing an API from within an application can sometimes cause some issues. For instance, when setting up a webhook notification instance using vROPS you only have a simple test button. But what if the application you want to access requires authentication and all you want to test is if you are able to access a URL via a HTTP proxy server?
The way in which you can customize notifications in vROPS has significantly improved in version 8.6. You now have the ability to use payload templates that can include all sorts of vROPS properties. This way you can make your alerts much more meaningful.
The nested ESXi appliances that William Lam provides to the community are great resources for testing. But what about interoperability? Can you run a nested ESXi 7 VM on a ESXi 6.7 server? Unfortunately the answer is; it depends. We can’t all be early adopters right? I currently work in …
Recently I found my self having to recover a VM that had most of it’s files deleted. They were removed by a script that was intended to clean up a staging datastore. Unfortunately the VM in question was left on that staging datastore and the script did it’s magic. The …
If you feel you want to take your VMware knowledge to the next level you may consider the VCAP-DCV Deploy certification. Achieving this advanced level VMware certification demonstrates you have hands-on experience deploying, optimizing and troubleshooting a VMware virtual infrastructure. It is not uncommon when you achieve this level of …
Today I had an experience that was not very different than some of the ‘I was today years old’ memes which are floating on the web. I was working on a script to detach a LUN on all hosts within a cluster when I stumbled on a contribution from LucD …
The problem In my homelab I’m using a server which contains both Gigabit and 10GbE NICs. When I first deployed ESXi version 7.0U1 the list of devices looked like this.

In this system the Mellanox isn’t connected to a switch (yet). So I didn’t notice this straight away. But …
