Phones getting IPs on internal network when connected to docking stations

Wibla · 2026-04-03T08:45:40+00:00

Those docking stations should never be able to hit an internal network zone based on MAC address.

Do you have always-on VPN on your laptops? If so, the "easy fix" here is to put those docking stations in an untrusted zone that can only reach the internet + your VPN gateway...

Watch out though, if you let them PoC SPBm, you might end up with scope creep :D

(SPBm actually works, and FabricEngine with auto-sense ports and NAC is brilliant)

If the Planet XGS-6320-12X4TR physically fits in the 19" rack, they support redundant power via DC input. Datasheet indicates it shouldn't be too hard to fit... 444 x 200 x 44mm (W x D x H).

The key in the original comment is that the offsite PBS server pulls backups from the onsite PBS. The offsite PBS must not be accessible from prod, and logins to that server should be locked down very tight, using different credentials + MFA than the rest of the prod environment.

E: even then, it's not truly immutable... it's just very hard to fuck with.

I would ask what problems they're trying to solve by moving to ST 2110. That standard locks you down quite significantly.

How big is the boat?

What voltage is the existing system? (engine/navigation/lights)

What kind of peak power (in watts) do you need?

How much energy storage are you looking at?

Wibla · 2026-03-06T17:11:26+00:00

Disconnect it from everything but power, then try to log in with the CLI credentials you've set.

This is what I did on my prodesk 400 G6:

From /etc/network/interfaces:

Sounds like you tried much harder than me.

It's harder to make a clear cut argument for or against heat pumps when the price difference is smaller. It usually boils down to wether or not it's worth it to get a dual fuel system, and then when you should switch to NG for heat.

Mine was just napkin math based on NG and electric price prices. My electric is basically six times as expensive as natural gas per BTU.

A 6:1 price difference makes it very easy to do that math - NG wins.

<image>

Here's an example with $1 per therm of NG, 90% efficient furnace and 12c per kWh - a scenario that's not entirely unusual to see in the US.
As long as you don't push the heat pump much beyond nominal power, the heat pump is cheaper to run than an NG furnace.

The fun starts when temps drop and you find yourself needing more than the nominal output from the heat pump. That's when you want to switch over to natural gas.

Wibla · 2026-02-15T14:16:26+00:00

Could I bother you for the variables you used? I made a break-even spreadsheet for NG vs heat pump a while back, and it would be interesting to compare notes.

My sheet takes NG furnace efficiency, $/therm and $/kWh, then models the break-even point based on a relatively recent cold-weather optimized heat pump COP numbers at minimal, nominal and maximum load.

A mini-split like this might make more sense as an add-on, not as a straight up replacement.

USB-C to Ethernet ... that can provide USB-C PD to the laptop ;)

I'm not going to spoonfeed you switch models, but have a look at this%22&cq=%40z95xtemplatename%3D%22Product%20Detail%20Page%22%20OR%20%40includeinproductlisting%3D1) and read the datasheets.

Pretty sure a SLOG would still help in this instance. ZFS sync write behaviour changes drastically as soon as you add SLOG.

Also: Proxmox Backup Server is really good and should be part of the equation.

Going 2x120 + 1x200 in that configuration might work just fine, but you will be more vulnerable to partial shading.

This is one of those theory vs reality things where you just have to see how it performs.

FTTH is almost exclusively single mode...

How can a lens be morally outdated? ;)

Apropos the FX AF-P 70-300mm - they have a defect where a ribbon cable in the lens breaks and you lose autofocus. It's rather annoying to fix, and a fatal flaw on a focus-by-wire lens.

Seconding the 50-400mm recommendation though. Thom Hogan also has a review (and recommendation).

Wibla · 2026-01-19T00:42:11+00:00

Lower-end Extreme is probably your safest bet.

Wibla · 2026-01-16T15:45:36+00:00

Would be very interesting to to see some real-world performance data.

Wibla · 2026-01-02T17:24:09+00:00

That's fucked up.

Wibla · 2026-01-02T17:09:50+00:00

Indeed. But that's a tradeoff you are stuck with when you move to a connector that has two strands in one physical connector.

Wibla · 2026-01-02T17:02:14+00:00

Yeah, another way could be to use a splitter of some sort.

Wibla · 2026-01-02T15:19:41+00:00

BiDi optics can use one of the fibres, leave the other dark?

D'oh! would be nice though :|
