I've been running my most recent Server built for quite some time now. I think Uptime was somewhere around 5 Months. Absolutely flawless. A few Days ago i started to have issues. Hard-Locks, Freezing...but absolutely zero log entries. Nothing. The Server was built with "off the shelf" Hardware and no ECC (even though the Ryzen CPU technically supports it, at the time ECC 3200 MHz Memory was still a lot more expensive than it is now) and is running a ZFS. Risky business, but it's "just" a home server. Would never built a server running mission critical stuff like that (and I've been doing that for over 10 years now as my main job). Over the last few weeks, i've been trying some stuff and had a pretty high memory load.

In any case, i also like Astrophysics and have some newsletters about Auroras and so on. They are extremely rare, here in southern Germany to occur. Yesterday we had one of the biggest and brightest I've ever seen.

But it got me thinking about my hard locks and crashes and i remembered, i had an account for ESA's SSCC (SSA Space Weather Coordination Centre). They have something called "Post-Event Analysis", where you can correlate certain timestamps to real time data, for example from DSCOVR ("THE" Space Weather Satellite).

For Auroras to occur, the so called "Bz-Value" is important. Basically, it tells the direction of the interplanetary magnetic field. If it's direction is towards the sun and towards the charged particles the sun throws at us, they get deflected. If it's with the direction of the solar wind, the particles "come in" and produce auroras...because the charged particles charge other parts - they generally charge oxygen, which results in green auroras - they also can do all sorts of stuff (and that's why spaceships, sats and other stuff floating around in space need shielding). The Value is measured in nanoTesla(nT).

There's also the Kp-Index...which was 7-8, out of 9.

So yeah - i'm pretty sure, i experienced a Single-Event Upset/Bit-Flip. Amazing stuff!

Hi,

been running PiHole with my FritzBox as DHCP Server for a while now. Just got Fibre and the new router doesn't support "only" setting an upstream DNS (neither does it support setting a domain suffix/local domain). I've switched the DHCP off and now PiHole does DHCP as well.

The FritzBox and the new Router added the domain suffix to recognized hostnames automatically, so even if i set up a fixed IP-Address on some device or machine, i could always use the hostname.local.domain without having to set a reservation.

Can PiHole/AdGuard/Technitium even do this? Do they need some extra configuration? PiHole does recognize the Hostnames correctly for some devices, but most are missing: For example, my Proxmox host was reachable with "pve.domain.local", it isn't with PiHole, even though PiHole identified the hostname. My Homeassistant isn't recognized at all, even though the IP-Address is showing up in PiHole. The Domain under "Advanced DHCP Settings" is set up.

Am i misunderstanding something or did i configure something wrong?

Thanks!
