I have moved last month from home made redneck style rack shelves to a very nice servers cabinet from LanKATT.
This model I have seen with different brands with just minors differences.
So this tutorial is applicable basically to all racks with same components.

Hello guys,

In this article I will show you personal thoughts and tests regarding this HDD enclosure from Raidsonic: Icy Box IB-3805-C31.

Check out my channel for other interesting videos.

I have bought Qnap TR-004 recently to use it as simple external enclosure with disks set in individual mode for a linux server. In other words: I had all disks visible separately in the system.
Unfortunately I had to return it for 2 reasons, important for my needs:

1. Inserting or removing a disk interrupts the USB connection with the computer

How to list network adapters:

[root@mini:~] esxcli network nic list
Name    PCI Device    Driver  Admin Status  Link Status  Speed  Duplex  MAC Address         MTU  Description
------  ------------  ------  ------------  -----------  -----  ------  -----------------  ----  -----------
vmnic0  0000:01:00.0  ntg3    Up            Up            1000  Full    68:5b:35:7f:07:8d  9000  Broadcom Corporation NetXtreme BCM57766 Gigabit Ethernet

Of course, the easiest way would be to use rufus via windows but if you do not have a windows around, you need a different approach.
Under macOS there is balenaEtcher but for unknown reasons it doesn't detect the ESXi image as bootable and the result is not bootable either.

What's left is a manual approach, via terminal, that should work under macOS or Linux.
Below is a way to do this under macOS. Under linux is not that different: you need to use fdisk -l instead of diskutil list.

Short and sweet: you need to create a bootable ESXi USB stick and the "normal" method was not doing it.
In my situation, I was using balenaEtcher but even if it was successful, the USB stick was not bootable. The tool did warned me when I have selected the ESXi iso.

So here we are. In order to create a bootable ESXi usb stick, you need to have:
1. ESXi iso image from vmware website (https://my.vmware.com/group/vmware/evalcenter?p=free-esxi7)
2. An empty USB stick.

Seeing this when running dmesg?

In this article I will show you how to create and set up a syslog-ng in docker container and redirect logs from another container to it.
You should have already a running docker set up. If you do not know how to do that, do a search on this page as I have created several articles for it. Also, web is full of it.

On a Macbook pro with Retina display you cannot get to native resolution in the system settings.
For example, on Macbook Pro 16 inch, the native resolution is 3072x1920 but the maximum available scaled resolution is 2048x1280. The reason is on the native resolution everything looks very tiny on this small screen.
Of course, this doesn't mean you cannot get to that resolution.

Let's say you are in my situation: you have bought recently a new mac, with Catalina (10.15) and you are switching from an older one that was supporting only High Sierra (10.13).

And you get this error when trying to do sudo port selfupdate.
