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.
