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...

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`'")

    $DNS_A_records | % {

        $hostA = "" | select "IPAddress" , "hostname"

        $hostA.hostname = $_.OwnerName

        $hostA.IPAddress = $_.IPAddress

        $hosts += $hostA

    }

}

$hosts = $hosts | Sort-Object @{Expression={[Version]$_.IPAddress}}

$hosts | Export-Csv $CSV -NoTypeInformation -Force 


$conv = Get-Content $CSV

$conv.Replace('","',",").TrimStart('"').TrimEnd('"') | % {$_ -replace ',','    '} | Out-File .\hosts.txt -Force -Confirm:$false


Get-Content .\hosts.txt | select-string -pattern "IPAddress    hostname" -notmatch | Out-File C:\Windows\System32\drivers\etc\hosts -Force -Confirm:$false

vSphere 7 - Specify a vmkernel adapter to use for NFS datastores Step By Step \ Walkthrough on a DVS

-
Image
 Recently I needed to setup a NFS server but needed it to specifically be on a specific vmkernel adapter. I found this KB https://kb.vmware.com/s/article/50112854 however there were some things missing so I decided to write this walkthrough incase it helps any one else. First thing , remove all NFS mounted datastores if you haven't already. I ran through this on 7.0.2 however is probably the same for other versions. Step 1: This is going to be on a DVS, so we want to go ahead and create a port group to silo off our NFS traffic. To make life easy, we will just call it NFS Static binding and elastic port allocation were the defaults so I let these there. If you are VLAN'ing your traffic modify this info here, and complete the wizard. Next put your host into Maintenance Mode We are going to add a New TCP/IP stack to the host. First check that you have not already created one in the UI by opening a browser to the ESXi host, navigate to networking > TCP/IP Stacks SSH into your E...

Horizon View 2-factor Authentication for Free! with Google Authenticator or others

-
Image
So after quite a bit of work on my proof of concept google authenticator server, a colleague pointed out that LinOPT has already created this, along a whole slew of other options. So after spending a couple of nights reading and testing I figured id post a simple walk-through to get this up and running in your environment. As mentioned in the title this is a Free solution , however if you are wanting to scale this in a large organization you would most likely want to explore their support contracts , this is a good fall back when things just don't work and this also help the developers keep this type of software free for the rest of us. To start off we want to create 2 objects in Active Director. The first is just a standard user account LinOTP will use to connect to your domain. You can put these any where in your domain as we will access them directly later. In my case i create one called 'LinOTP Svc' and put it in the default Users OU. Next create a Global or ...
