OK I decided to write this up after unsuccessfully being able to find all the required info I needed in one place. In this setup we will be using Ubuntu Server 22.04.2 LTS as the OS. I have this running on a home lab ESXi server 8, on a HP Compaq Pro 6300 SFF CPU = Intel Core i7-3770 Installed Memory 16 GB I have some 10K SAS drives installed for the VM's If you have not already, navigate to  Get Ubuntu Server | Download | Ubuntu and download the 22.04.2 LTS ISO Next Lets create our VM that we are going to run this in. *Note Im using ESXi however you can probably do this in Workstation, Fusion, VirtualBox etc The main things to note on the VM creation. Set Ubuntu 64 bit as the guest OS Set your CPU relevant to the physicals CPU, I will be starting with 4 VCPU Set your Memory to as much as you can tolerate, I will be using 12 Disk Space - we are creating a 100G swap file, and the rest of the file can take up some room , so more is better if you can afford it Dont forget to add the U...

VMware vSphere vCenter and ESXi Home Lab shutdown script with PowerCLI

-
Some times you need to shut down your lab in as efficient way as possible. I do this quite often as I don't like leaving my home lab running during various events (thunderstorms, weekends , vacation etc). And I really dont like having to click , wait, click, wait, click.... wait some more to get every thing down. So I wrote this script to power down my lab, Ill walk you through what it does and the completed version will be at the end of this post. (I'm also including a start-up script I use as well) First we need to import our power CLI modules and tell the script to ignore any self-signed or Invalid certificates ( If you want more info on setting up powerCli see the beginning of this post for more info) ------------------------------------------------------------------- Import-Module VMware.PowerCLI Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false ------------------------------------------------------------------- Now we need to setup our credential...

Extract remote DNS to local hosts file

-
So with the whole work from home process, my company recently made changes to its VPN policy to block local DNS queries. This has completely screwed up my work flow for testing. So with a bit of google-ing  and duct taping some code I have come up with a simple powerslell script to extract the DNS zone from my lab to my local host file. Enjoy! #VARIABLES $scriptpath = $MyInvocation.MyCommand.Path $dir = Split-Path $scriptpath $CSV = "$dir\DNS_A_records.csv" #parameters $DNSServer = "dc1.home.lab" $Zone1 = "home.lab" #$Zone2 = "me.myzone.local" #SCRIPT MAIN clear $DNS_Zones = @() $DNS_Zones += $Zone1 #$DNS_Zones += $Zone2 $hosts = @() $DNS_Zones | % {     $zone = $_     Write-Host "Getting DNS A records from $zone"       $DNS_A_records = @(Get-WmiObject -Class MicrosoftDNS_AType -NameSpace Root\MicrosoftDNS -ComputerName $DNSServer -Impersonation 3 -Credential HOME\administrator  -Filter "ContainerName = `'$zone`'")    ...
