Documenting My Home Network/Lab

I’m a big believer in learning by doing. Over the last couple years I’ve built up a nice little home network/lab where I host various applications and test new tech. I will hardly be the first person to make this recommendation, but if you are able to get your hands on some hardware to set up a home lab I would highly recommend it. Any old computer you can turn into an ESXi host is enough to get started. I have learned an enormous amount about various technologies that I wouldn’t have had much opportunity to learn elsewhere. First, the obligatory picture:

The breakdown:

  • Ubiquiti Edgerouter X
  • Ubiquiti UniFi AP AC LR (not pictured as it’s located in a location central to the house)
  • ARRIS SURFboard DOCSIS 3.0 Cable Modem (SB6183)
  • Cisco SG300-28
  • Cisco SF302-08MPP
  • TRENDnet 24-Port Cat6 Patch Panel (22 runs in the house, minimum for 2 per room)
  • Startech 12U 19-Inch Desktop Open Frame 2 Post Rack
  • Raspberry Pi 3 Model B
  • Lenovo TS140
    • Xeon E3-1226 v3 3.3Ghz
    • 16 GB Ram
    • 44 TB (raw) of various spinning storage, mostly WD reds (yeah, yeah, I know. I’ll get a NAS eventually)
  • Old computer serving as my ESXi host
    • Intel Core i7-2600K Sandy Bridge Quad-Core 3.4GHz
    • 16 GB RAM
    • Samsung 840 EVO 250GB SSD
    • 5 TB (raw) of WD Reds
  • 2x CyberPower CP1500AVRLCD UPS
    • One is for my “core” equipment (network stuff/TS140), the other is on the ESXi host

I am a huge fan of the Ubiquiti hardware. This combo was one of the first purchases and its pretty fantastic to not have to regularly “reset the router” like seems to be necessary for just about every consumer router/AP. I picked up both switches off of eBay and have been pleased with them. Some Cisco purists dislike the small business line but they’ve been great for my purposes. The SG300-28 (gigabit) is my main switch and the SF302-08MPP (fast ethernet, POE) runs my cameras. I didn’t need to have separate switches, but based on what was available on eBay this was perfect for my goals. If we’re being honest, need went out the window a long time ago anyway. I run a handful of VLANs and 2 separate physical LANs to segment off the different portions of my network. Necessary? Probably not, but where’s the fun in that? This has allowed me to tinker with VLANing and setting up firewall rules. Fun stuff!

The TS140 runs AD, DNS, Blue Iris (cameras), and acts as a file server. My storage situation could certainly be improved, but all important data is backed up locally and remotely and any data that I consider to be less important is at least mirrored to separate local storage. My Raspberry Pi runs PiVPN which is a super simple way to run OpenVPN and is much more manageable than my previous setup where I ran it on my router. The ESXi host runs the following VMs and applications:

  • Plex and related apps
  • Borg Backup
  • Crashplan
  • Nextcloud
  • Kali box for security tinkering
  • Windows VM for when I need to run Windows specific apps
  • LibreNMS
  • Whatever I feel like playing with at the moment

Each of my Linux boxes are running Ubuntu 16.04. All VMs are regularly backed up using ghettoVCB.

That’s pretty much it for now. I will update when I inevitably add more!
