HE Sage Certification

July 26, 2019 | Certification, HE, IPv6, Networking | No Comments

Hi readers,

This post will be all about Hurricane Electric their IPv6 certifications.

Myself, I recently got the Sage certifications (currently waiting for my shirt to be delivered) and I learned a lot from it.

There are different levels of the certifications. You have practical questions, where you have to setup IPv6 on your server, and you have technical tests, which consists of technical questions about IPv6.

IPv6 is importan. IPv4 is getting exhausted. IANA already allocated all of the IPs that it can. (without having to do a major re-vamp of the internet, for example, having to allow 240.0.0.0/4 -currently a reserved address space, former class E network-, would require a major update for all of the infrastructure, so this won’t happen most likely.)

It is important that more people learn about IPv6 and that it becomes adopted widely, as it won’t take long before all RIRs do not have any IPs left. (Like ARIN).

As a bonus, if you get the Sage certification, you get a shirt!

Thank you for reading this and I hope that you will enjoy the HE IPv6 certification as much as I did.

Thank you for reading.

Hi readers,

As some of you may know, I am from The Netherlands. Where I live, up in the northern area of The Netherlands, it is 37°C while I am writing this post.

Some weather stations in the country have recorded 40 °C , which has never been seen before in our country.

Currently I am working on the follow-up post of the Horizon lab,and I am also working on a post about vRealize Network Insight and vRealize Log Insight.

Stay safe and hydrated everyone!

Thank you for reading this short post. I wrote this as an update for you, the readers.

Hi readers,

This short post will be about how I had to set-up a static route on ESXi to my VPN subnet.

My setup is as follows: I have an ESXi server in DC1, and a ESXi server at home. The Home ESXi server has vCenter and vRealize Operations Manager on it. My goal was to have vRealize Operations Manager give rightsize advise on VMs on both my home server and the server in DC1. For this to work, I need to add my DC1 server to my vCenter server. I created a datacenter for it in vCenter, and I created a vmkernel adapter on the LAN network of the DC1 server. There is an IPSec VPN that links the remote network and my local network.

vCenter could talk to the ESXi server, but the ESXi server did not know how to talk back. The solution was to create a static route. I simply ran this command on the DC1 server (I enabled SSH and use that to execute the command):

esxcfg-route -a 192.168.254.0/24 172.16.100.1

And that was it! It started to work. In a future series, I will be explaining how to setup vRealize Operations Manager.

For now though, I’m still playing around with it.

Thank you for reading this post.

IPv6 and BGP adventure

July 18, 2019 | BGP, HE, Networking | No Comments

Hi readers,

This post will be about my ‘adventure’ of getting my own AS number, IPv6 subnet, and peering with Hurricane Electric to announce my IPv6 subnet over a 6to4 tunnel.

I started to chat with someone on Discord about getting my own IPv6 subnet. They’re not that expensive. I got mine from SnapServ. I purchased a /44 IPv6 subnet and an Autonomous System Number.

After having successfully set-up a 6to4 tunnel with Hurricane Electric before, I decided to sign up for a BGP tunnel, so I can use my own IP address space.

I got my ASN and /44 subnet from SnapServ. A /44 IPv6 subnet is 16 /48 subnets, and the /44 is that smallest that they had. It’s very affordable.

My AS currently peers with Hurricane Electric. Though this may change soon, as their support has been ignoring my tickets, twice. There is an update of that coming later.

Currently I’m getting packet drops from their tunnel… So we will see how it goes.

For now: made two tickets, got ignored on both my their support staff.

To be updated..

Hi readers,

Tomorrow I’m getting a 2TB drive that I can put in my server. I plan to use it for an apt mirror, and to run a test environment on it for VMware Horizon.

It has been a while since I have used VMware Horizon, so I hope that my memory won’t let me down. If it does, then there’s always the documentation… (and YouTube).

For a short while it will also be used for my to make screenshots of VMware tutorials that I write for Hetzner’s wiki. I’ve written a vCenter and NSX one, and I’m almost done with the screenshots for the vCenter PR. The NSX tutorial does not have a PR yet.

On that note, currently I am working on two blog posts. One is about my adventure with NSX, and the other post is about BGP, and how I peer with HE to use my own IPv6 subnet at home.

Stay tuned for that! I will update this blog post when the drive arrived and when it’s installed.

Thanks you for reading this post.

UPDATE 09/07/2019: Hard drive got delayed in shipping, have to wait another day.

UPDATE2 09/07/2019: ProLiant Dl380G6s and Seagate drives don’t work well.. Getting a new one on 12/07/2019

UPDATE 12/07/2019: The new drive (WD Blue) has arrived and it is working great!:

Server update: it’s all (almost) set-up

July 1, 2019 | BGP, VMware | No Comments

Hi readers,

Welcome to this server update post. I’ve made some changes to the system, and it’s almost done! Sadly, right now it’s come of a stop, because of lack of storage space.

It’s not a big update. Hardware-wise, nothing changed. I am planning to go 10 gigabit though, whenever I have more monthly income, because with what I earn right now, it would me impossible.

VM-wise, I added a virtual machine for peering with a Virtual Internet Exchange. Currently I am working on my own Virtual Internet Exchange, which would be for people who want to learn BGP, routing and more.

Sadly, the thing holding me back from expanding (A Horizon lab, Steam Cache and apt mirror), is that I am out of storage space.

In the server, there are two 500GB SSDs that I already had. Both come from my old servers. There is a second 320GB HDD in there, a very old one, that I put in as an emergency. The server only takes 2,5″ drives, so I’m limited to that. It supports SAS, but I have all SATA disks in them, since SAS drives are too expensive for me. I’m trying to get a 2TB SATA drive, which hopefully I will be able to buy in August or September.

Stay tuned, there will still be blog posts, I have one planned for my GNS3 lab, and a to-do post where I will explain what I’m saving up for and trying to get.

Thank you for reading this and see you soon.

My server

June 22, 2019 | Networking, Virtualization, VMware | No Comments

Hi readers!
Welcome to my first real blog post! In this post, I will be explaining my current server, my trusty HP ProLiant DL380G6.

It’s armed with two Intel Xeon X5650s, which each have 6 core and 12 threads, making it a total of 12 cores and 24 threads. It has 144 GB (18x 8GB) of ECC RAM, and it currently have two 500GB SSDs, along with a single 320GB HDD.
Here is a picture:

Not the sharpest picture, because it was made from quite a distance with my Galaxy J7.

It runs VMware ESXi 6.7 on it, along with a vCenter Server Appliance and NSX. Here is a screenshot of the VM view in vCenter:

I run my firewall on it, which is OPNSense. I previously used pfSense, however it was being buggy with my BGP tunnel for IPv6 (more about that in this post.)

Other than that, I run WDS and MDT on it, so I can easily install Windows over the network. I have my GNS3 VM on it, so I can have it running 24/7 and can access it from anywhere, I use it to learn networking. (More about that in this post.)

I have a Discord Bash bot VM on it, it’s just a python bot that I’m making, to leanr python. Next to that I have a Linux and Windows Workstation VM, that I can login to when I’m not home. ix90 is a bit of a weird project that I’m going into more detail off here.

Everything connects to an Ubiquiti EdgeSwitch 24 Lite. My parents their network runs on a UniFi Security Gateway and a UniFi 8 port POE switch. The EdgeRouter X is just there for me so I can test things with it. Here are some pictures:

That’s a quick overview of my basic networking setup, this post will later be updated with everything about NSX when I have that working.

Introduction and my story

June 22, 2019 | Uncategorized | No Comments

Hello reader,

Welcome to my blog! Let me introduce myself.

My name is Michael Goossens, well, that is my official name. I’m a female born male from The Netherlands. Currently, on most of my profiles that are official (at companies), have my legal name, Michael. Though it will change to Michelle, eventually 🙂

Currently, I am 17 years old. I’ve been into computers and servers since I was six years old. It’s in my family, my father and uncle had a company where they repair computers. Unfortunately, my uncle retired and my father switched jobs, so it no longer exists.

I discovered my interest in servers when I was about 11. I started by playing around with Windows Server 2008, got into making an Active Directory Domain, DNS, DHCP.. Basic network admin and sysadmin stuff. I did this using old PCs that I had.

Then, when I was 12 or 13, I discovered virtualization. VMware… Oh boy. Things may have gotten a bit out of hand with that. More on that later. I started with VMware Workstation, running Linux in a VM on my PC. Then I went to nested virtualization, where I had ESXi 6.0 running inside VMware Workstation. After watching lots of documentation and YouTube videos, I started to get the hang of it.

When I was 15, I got my first real server. A HP ProLiant DL140G3, with two Intel Xeon X5355s, for a total of 8 cores, with 32 GB of ECC RAM. Man was I ever excited for it. It was LOUD, but it was worth it. (Seriously, it sounded like a jet taking off, all the time.) I quickly armed myself with an USB flash drive with the ESXi 6.0 installer on it, and after installing it on my single 500GB Samsung SSD, I threw some VMs on it. Windows Server 2012 R2 for ADDS and DNS, and a second VM that had a fileshare on it. (I was well aware that I could run that on one VM, but I had the space for at least two VMs, so I made a second one, just because I could. Hey, I was exploring after all.)

After a few months, I decided to explore Horizon and vCenter. Not at the same time, that wouldn’t fit on my server. First off I started with vCenter. Creating a Datacenter, adding the host, playing around with dvSwitches… It was a lot of fun. After a few months, I got myself a second server with the same specs. Now I could run vCenter and a basic Horizon setup at the same time. I was so happy, but… My parents were not, with the powerbill of the servers being 350W all day and night.

By this time, I’ve gotten off elementary school and high school. I started at a school to get my System and Network Admin degree, however I dropped out, as with my medical issue (hyperacusis; hypersensitivity to sounds, in my case, hearing everything 8-10x louder), I was unable to go to school and finish the degree, so I dropped out. This also means, that I’ll most likely never get my driver’s license, or be able to go with public transport.

When I was 16, I came clean to my therapist that I wanted to be a woman, on my birthday, March 29. I also told it to my parents that same day. I felt very relieved, knowing that they supported me. After a month, I went to a special therapist that is helping me with my transitioning. More about this later.

When I turned 17, I’ve already been wearing woman’s clothing, and shaved a lot. Some people close to me called my Michelle. Though to this day I still have to tell the rest of my family, not a lot know. Hopefully, I will be signed up to the hospital for hormone therapy, at around September 1st. Can’t wait for that!

Next to that, I also got myself a better server, a HP ProLiant DL380G6. It’s armed with two Xeon X5650s, for a total of 12 cores and 24 threads. It rocks 144GB ECC RAM and has two 500GB SSDs, and a single 320GB HDD. Sadly I’m out of space right now, and have no money to buy new drives. But that’s not the point of this introduction. Right now, I run ESXi 6.7 on it. I also run a vCenter Virtual Appliance on it, and I have NSX deployed. I recently got myself a book, Mastering VMware vSphere 6.7. I’m learning all about vSphere and NSX now, with Horizon soon to follow.

I’ve had been having a depression since last year, so I didn’t get to write anything on my blog. But it’s been settled now, and I’m ready to be active on my blog.

Thank you for reading this and I hope that you enjoyed your stay. I will keep this updated as things improve.
