If you do this sort of thing often, I'd love to chat further. I'm basically trying to automate this sort of manual research around companies with a library of deep research APIs.

Had a show HN last week that seemed to go under the radar: https://news.ycombinator.com/item?id=45671087

We launched corporate hierarchy research and working on UBO now. From the corporate hierarchy standpoint, it looks like the Delaware entity fully owns the Estonian entity. Auto generated mermaid diagram from the deep research:

This guy on YouTube made several videos reviewing these and also doing some WireShark analysis, also on NanoKVM.

Personally I'd never use these on an interned facing network. But they can still be handy for local only.

This is why I recently went with a PiKVM. Pricier and clunkier but much more open and transparent.

I think products like JetKVM are targeting hobbyists and small outfits; corporations who aren't on a public cloud are using stuff like idrac, ilo, or dedicated rackmount KVM hardware.

I don't think this is nearly at the stage of "corporate customers putting into serious trust"

Buildjet (the parent company) looks to be a pretty small company with currently modest revenue[1]. I agree that the absence of people on both webpages is sort of odd. I think it make more sense for their original service (CI workers) than it does for a hardware product.

Estonia is (trying to be) the Delaware of the EU for companies. They make it deliberately convenient for any Europeans to incorporate there, so I wouldn't read much into that.

It does share similarity to a rebranded Sipeed NanoKVM model already sold in China.

Would have to dump the flash with proper tooling, and load up a clean OS on a blank chip to even begin checking for issues. Mostly, these gadgets are purposely built like garbage for a number of reasons.

If I needed a DIY KVM install for a home-theater, I'd just setup a https://pikvm.org/ install. =)

People familiar with KVM switches have the reverse issue with the Linux kernel thing. ;)

Classic TCP (TLA [Three Letter Acronym] Collision Problem)

The virtualization KVM is the new kid to the block. Back in the day the best way to get multiple machines controlled was to just have multiple machines sharing the same monitor, keyboard and mouse.

I thought that was RDS (remote desktop).

It's difficult for me to tell how many of the issues in that thread are serious, because there also seem to be a surprising number of people who come back to say "I solved it by enabling h264 in my browser".

On the other hand there are people who say "I ordered three, two work and one doesn't" which seems like pretty good evidence there can be real issues with the hardware.

I’ve been using the glinet comet kvm for my homelab and have no complaints. Their cloud is optional and I don’t use it. The built in tailscale client does what I need it to. I use it with their ATX power accessory to manage physical power on/off when needed.

Given that these things have bare metal access, keeping them off of the public internet seems wise no matter what though.

I'm excited to take mine apart soon and figure out why this might be happening for those people.

> people[0]

I read that as you were selecting the first record from the people array

> The tariff situation is unfortunate

I wish there was a way of ordering from a non-US source so I didn't get hit. I'm not in the US, so it feels silly that I have to pay the American import tariffs on Chinese goods!

What justifies the V4 Plus being worth $350? They're using the CM4 so they’ve made a PCB, but what hardware are they adding over the peripherals available on a Pi 4/5? All I can tell is an additional Ethernet port, a SIM card tray, and an “ATX controller”.

What does the board look like, why can’t I DIY that version, etc. Are they just trying to make it up with the software (that I also can’t tell what it looks like).

The JetKVM software is also open source: https://github.com/jetkvm/kvm

The JetKVM is very impressive looking at a great price. Until recently it wasn't really available in the US but it looks like it is now/

The V4 Mini is a very nice piece of hardware. I paid $300 for one in April from Amazon. I also got PiKVM running on a Pi Zero 2 W and it worked fine but was a bit squirrely. Having the purpose-built device is nice.

You can also use a Pi Zero 2 W as a serial console: it has a USB On-the-Go port perfect for the purpose. But the KVM approach is more generally useful since you can access a consumer BIOS from it.

I can buy 3 or 4 x JetKVMs for 1 PiKVM, pretty hard to justify going for PiKVM unless there is a PiKVM feature you need

Tiny pilot is also an option

JetKVM is over 50% less what?

Yeah there are sort of some BMC/IPMI options like [0] but all of the ones I've seen still require some kind of special (generally proprietary) internal connector on the motherboard, which might not be "HDMI" exactly, but still violates the spirit of your requirements.

Something like Intel AMT? Some prosumer motherboards like ASRock Rack have out of band management controllers in them.

or that just connected over usb and acted as a usb display adapter

That seems to be one of their products

Teradici is that, but too expensive for home users.

Since there's no independent audit of these and no way to prove that these aren't being intercepted, I wouldn't be bragging about voluntarily installing potential infrastructure vulnerabilities.

It doesn’t require the OS on the target hardware to be running, and no other software can get in the way. It can also connect via a separate network than the one the computer is on (if any).

it’s useful to be able to get into the bios for remote support situations of critical servers, I guess

> what does this do that an app like AnyDesk doesn't

Work when the network config on that particular computer is down/borked.

I believe the primary use-case for devices like this is debugging "Why isn't this server rebooting?" without driving to the datacenter. Good luck figuring that out with AnyDesk or SSH.

I have an aurga. I've found their client software to be lacking.

I get that too on a machine running Mint Cinnamon. It also happens from the BIOS screen, so I don't think its a Linux issue. A re-plug fixes it, but that's not great for a remote access device.

The KVM can be plugged into any system not just those with a spare PCI-e and you can move it around easier without having to bring systems down if you don't need the direct power control which is the main use case of the PCI-e board.

Something like the NanoKVM-PCIe? I have both JetKVM and NanoKVM-PCIe, its nice to have options.

Operates at a hardware level, separate from the target machine rather than software in the OS.

With RDP/VNC what do you do if the machine fails to boot? Or RDP stops working for some reason and you can't SSH in?

Or for installing a headless OS on a new machine.

I'm sure there are more specific usecases as well but that's what I mainly use remote KVM devices for at home.

A few things: 1/ the system doesn’t need to be connected to a network, or can be on a private/secured network. 2/ You can make changes to BIOS and other elements of the system that the OS can’t “see”. 3/ If the system is sleeping or shutdown, JetKVM can send a wake-on-LAN signal/magic packet.

I’d say for many use cases, it’s not better than RDP/VNC, but if you’re looking access that is independent of the network and state of the system, JetKVM can’t be beat.

Add-on, almost lights-out remote management.

Without lights-out management, eventually physical access to power cycle will be needed.

For systems people care about, they already have BMC (Supermicro), iLO (HP), iDRAC (Dell) controllers.

Anything that can capture HDMI and spit it securely over a wire without some cloud-dependency bullshit, present "virtual USB" or input over the network, and close a RST circuit momentarily would do the job. The problem is, in the name of consumerishism and convenience, none of these home-gamer "solutions" have been independently audited that I know of by any reputable firm. (A competitor, NanoKVM, is known to be shady AF downloading serialized binary crap. It talks to tailscale without user permission, communication, or approval. Never use it for anything.) Don't trust something simply because there's press release or social media hype about it. I have to endure constant Cloudflare CAPTCHAs because it's probable that a large fraction of other customers on my ISP have pwned IoT (cameras, doorbells, whizbang startup weather station, etc.) DDoSing and hacking the rest of the world.

PSA: For the love of the sysadmin gods, please don't use desktops as servers. ECC RAM, HA, duty cycle, lights out management, and vendor support are completely different beasts compared to retail gear.

For non-lights-out, host-based remote desktop that can be self-hosted, RustDesk is able to work locally without relaying to any clouds. And using WG (non-TS) for "VPN"/remote network bridging, that's a pretty compelling option. I haven't yet checked if it can work in an air-gapped environment but I think it might work; but if it doesn't, that would be sad.

RDP/VNC don’t work when the computer is off. Or the computer’s network card is down.

Looking at the product itself, it looks like it barely squeezes the mini-HDMI externally as is, let alone then PCB/internal available space.

I don't think there is, in fact, room for a full HDMI port. Mini HDMI is a compromise, and everyone knows it. It wouldn't have been included if full size HDMI was feasible.

Looks like they are coming: https://www.gl-inet.com/products/gl-rm10c4/?utm_source=websi...

get a esim adapter (ie. euicc in sim card format), find a plan on https://esimdb.com/, load it onto the esim, and plug it into your iot device.

Hopefully you are in a network that allows P2P! Then STUN just works and you can use any of the public servers (CloudFlare, Google, Twilio...)

Running your own TURN server would be trivial also. I have been tempted for a long time to make a 'TURN in a Box' that does autoconfig so people can run it easily on Hetzner/AWS

They made an add on board that you wire between your case buttons and the header on your motherboard so you can than then 'press' any of the buttons.

there's this add on which allows it to do front panel/power stuff

https://jetkvm.com/products/atx-extension-board

I have the PCIe version of NanoKVM, and I am also happy with it.

The big advantage of the PCIe version is that it does not take up space on the desk and all the cables for ATX power control an inside the PC case.

Full-sized HDMI is nice, the only limitation here is 1080p resolution. 1440p or higher would allow mirroring the output on the main monitor to the NanoKVM, but this probably a weird use-case anyway.
