vRA DNS requests flood

 Knowledge Transfer: 

Today, I finally figured out why my vRA system was killing my PiHole. vRA wanted to lookup itself in IPv6 form. I do not run IPv6 in my home and have it disabled in the home network. I needed to disable the IPv6 system in vRA. So, I did the following on vRA 8.6: 

sysctl -w net.ipv6.conf.all.disable_ipv6=1

then ran a reboot. 

While I was also in in the system, I added DNS records to the "hosts" file just to help the system. I hope this helps others like me who don't have IPv6 running in the homelab. 

Have a great day!

Using MBR with older hardware and VMware ESXi 6.0 and 6.5

I will try to make this short. After hours of struggling to install ESXi on a USB drive I figured 2 things out: My hardware can only boot from USB with the “formatwithmbr” flag set during install Newer ESXi can only seem to see filesystems formatted with FAT32 meaning 8GB or greater. Anyway, it’s not hard to do either, but it is a pain. During the very first screen you should press <Shift> + <O> to get the options line to show. You will edit it to read: “runweasel formatwithmbr” That will make sure that the install runs if the system BIOS only allows boot from USB if it is running MBR instead UEFI. Hope that helps!

Ansible: Adding Ansible users and SSH without SSH keys

I wanted to add a page that makes getting Ansible online a bit easier. I am assuming that you have Ubuntu 20.04 installed and have SSH already working on it. Adding Ansible user to target machine Log into target server using existing user over SSH Change to root user sudo su - Add new user adduser <user> Follow wizard Change user access for sudo usermod -aG sudo <user>  Change to that user su <user> cd ~ Generate SSH key ssh-keygen Adding user data to Ansible host file. I am assuming you have already set up your Ansible host file. Edit the host file sudo nano /etc/ansible/hosts Add this block to the bottom of the file. [all:vars] ansible_python_interpreter=/usr/bin/python3 ansible_user=<user> ansible_ssh_pass=<user password> Test ansible -m ping <target host IP>  Profit SideNote: This is best used only in  secure environments  as anyone with access to this server can do bad things on your servers.  USE WITH CAUTION!!!

Getting Rancher LongHorn to work with RancherOS on vSphere

I was looking for an easy solution to getting a testing environment ready to explore Kubernetes (K8s).  I wnet through several itierations and testing to see what would be the best fit. I found Rancher to be a great solution for me. I run a small lab host at home and Rancher allowed me to deploy a K8s cluster quickly with many bells and whistles that I need to see the potential of K8s without getting lost in the process.  Rancher 2.4 is what I am running. I am running it as a docker container. I am deploying RancherOS nodes in my home lab using the vSphere plugin within Rancher.  One of the big hang ups in other K8s quick starts is shared storage. Rancher offers LongHorn and it is a clustered solution that is native to the deployment. However, it requires just a bit of tweaking to get it to work with RancherOS. Here is the process:  **If at first you don't succeed, start with sudo ! Go to the console of the RancherOS VM deployed. IT should already be deployed with th...
