Want to learn about how a computer works?
Not- at a high level....
But, at a very, very low level, where you literally build a functional computer from transistors.
If so- this is a list of resources which I have found extremely handy for myself.
Also, because ADHD.... there is also a list of automation centric games, channels involving lasers, plasma, etc.
This post outlines how to accomplish the following activities:
This post centralizes data for configuration of Mellanox ConnectX Series NIC (Tested with CX3, and CX4)
This is part two, of a three post series.
Will changing the link speed of your current NIC, affect Power Consumption?
For me- I have 100G NICs in my SFFs. I don't need the full throughput.
So- will reducing the link speed, impact power consumption?
For this post- I will benchmark and determine the impact.
So... Near the end of 2024, I ended up cleaning up my rack, and making everything nice and tidy.
If- you missed that, have a look at the 2024 Homelab Summary
For the next problem- my networking closet is an absolute disaster.
There are wires hanging everywhere... There are switches, and cables everywhere... its a mess.
I plan on building a frame, with DIN rails for mounting all of this hardware.
I see tons of racks. I see tons of mini racks. I rarely see DIN-mounted networking.
Part 1, is building the frame which will hold all of the components.
This is all wood and construction. Nothing technical.
Just a short guide on how to migrate a VirtualBox VM on Windows, to Proxmox.
Have... a full root partition on proxmox?
root@kube02:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 126G 0 126G 0% /dev
tmpfs 26G 21M 26G 1% /run
/dev/mapper/pve-root 94G 94G 0 100% /
Confused because your boot disk is much larger in size?
Well, its because Proxmox by default, partitions the root disk with LVM, Regardless if you are using it to store data.
This post detail completely removing the data partition and extending the root partition
Many years ago, I had setup a system which would automatically sync my Edgemax's configuration to a local git repo.
It worked so good, I had completely forgotten about it. During a firmware update last year, it had stopped working.
So- I went through, fixed and updated the scripts- and I am now sharing them with you.
I have swapped between Unraid, and TrueNAS a few times over the years.
Often, I stumble upon threads asking... Should I use Unraid? SHould I use TrueNAS?? Which one?!?
Well- I'm not going to tell you which one to use. Rather- I will give you the reason I personally use Unraid.
Want connectivity faster then 10G?
Well- I have a list of NICs, switches, and notes.
This month's goal, is to update the network to provide isolation, and separation between LAN subnets, and my server subnets.
Aka, if I go unplug my rack of servers- The internet should remain unaffected for members in my household.
Want the old right-click context menu back?
Copy/paste the below script into an administrative command prompt. Thats it.
:: Set "Old" Explorer Context Menu as Default
reg add "HKEY_CURRENT_USER\SOFTWARE\CLASSES\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /ve /f
:: Remove Explorer "Command Bar"
reg add "HKCU\Software\Classes\CLSID\{d93ed569-3b3e-4bff-8355-3c44f6a52bb5}\InprocServer32" /f /ve
:: Restart Windows Explorer. (Applies the above settings without needing a reboot)
taskkill /f /im explorer.exe
start explorer.exe
:: Empty Comment (Prevents you from having to press "enter" to execute the line to restart explorer.exe)
A few months back, I noticed one of my ESP32s, got smoked during a few nasty thunderstorms.
And- it got me thinking- what happens if a large surge hits my house?
Is, it going to smoke my fridge? My TV? How about my server rack full of expensive gear?
So- I went on a project to upgrade the surge protection for my house.
For years- I have been using a combination of Sonoff S31 Plugs and a Kasa HS300 Strip to monitor, and measure my power consumption.
This- allowed me to fully visualize my rack's power consumption, into a sankey diagram.
However- the form-factor of neither solution was ideal, and as my rack has become nearly full, I needed a better solution as PDUs filled with smart-plugs, isn't exactly ideal.
The issue is, there are not many 120v PDUs, for a 24U rack. As a matter of fact, there are not many zero-U PDUs at all for 24U racks.
But- I finally found an option, for a fully managed PDU, with INDIVIDUALLY metered and switched outlets, which CAN2 plug into a standard 120v outlet.
So... normally when you want faster networking, you can just upgrade to faster NICs (10g, 25, 40, 50, 100g.. etc...).
However, in the case of my Synology DS423+, you get, two 1G ethernet ports with no expansion.
You would think the best course of action, would be to leverage LACP- however that is NOT the case.
Enabling Multichannel can double the amount of bandwidth per client, where as LACP, depending on hashing, only gives benefit up to the performance of one port.
This post details how to enable multipath for SMB, and how to configure iSCSI on linux with multiple paths.
This is a very short post on how to debug DDNS for Unifi.
I have a love-hate relationship with Unifi.
One of the things I absolutely hate about Unifi, is their "Layer 3" switches.
IMO, its a marketing gimmick, and an absolute joke.
This- is a short post which details how to resolve a few random errors you may experience with proxmox.
This post is for you, IF, you are experiencing any of these errors:
