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

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.

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

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

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.
