because all the other programs, protocol are working fine.

With the shown firewall configuration nothing but NTP should work? You’re dropping outgoing packets by default.

Update your nftables rulefile or use nft commands to update your firewall to the following:

# extract
chain OUT {
    type filter hook output priority 0; policy drop;
    udp dport 123 accept

    limit rate 3/second log prefix "Nftables Blocked: OUT: "
}

chain IN {
    type filter hook input priority 0; policy drop;
    ct state established, related accept

    limit rate 3/second log prefix "Nftables Blocked: IN: "
}

Blocked pakets will show up in the kernel log (dmesg/journalcl)

If you want more information on why it is blocked then enable nftrace for those packets

nft add rule inet/ip/ip6 tablename OUT udp dport 123 meta nftrace set 1
nft add rule inet/ip/ip6 tablename IN udp dport 123 meta nftrace set 1
nft monitor trace

Or

nft add rule inet/ip/ip6 tablename OUT meta nftrace set 1

Or maybe even

nft add rule inet/ip/ip6 tablename PREROUTING udp dport 123 meta nftrace set 1

Additionally you can use tcpdump -i <interface> to show network packets before they enter the firewall, there you should be able to tell what it’s a trying to do.

Pro tip: If you’re using openwrt or other managed network components don’t forget to automatically back those up too. I almost had to reset my openwrt router and having to reconfigure that from scratch sucks.

If logging is down and there’s no one around to log it, is it really down?

That won’t work in most cases, all https traffic isn’t cached unless you mitm https which is a bad idea and not worth it.

Only cache updates those are worth it and most have a caching server option.

Infrastructure diagram? No! In this homelab we refer to the infrastructure hyperdodecahedron.

Valve’s testing indicates that Cyberpunk 2077 is Verified on Steam Deck. This game is fully functional on Steam Deck, and works great with the built-in controls and display.

Well, you can do that too by just marking the time range and repeating the appointment every day(/monday/…).

Just use multiple calendars?

I use Davx^5 and radicale to sync one (my own) calendar but you could also have multiple and distribute as needed.

I’m not a car expert or planning to be.

Anyways I’m going to build my first car by hand.

I have set up Tor secret services in the past to do this.

The service exposed the SSH port which could then be accessed from anywhere as long as you can connect to Tor.

I don’t know anything about Talos but can you try it in a VM with a test disk? That should answer all your questions and show you possible pitfalls.

for a homelab I don’t think it’s feasible to fully review the source code of everything you install

Here’s what you can actually do:

• Consider if you actually need the application and stop applications you don’t use
• Don’t allow public access unless it is necessary, consider VPN/reverse proxies with client authentication (if supported)
• isolate applications that don’t need to talk to each other
• • see also rootless podman, firewalls, virtual machines, etc
• • don’t forget network access, if everything runs on 127.0.0.1 and every service shares it then they can all talk to each other! (See also network namespaces or VMs)
• Don’t reuse passwords
• keep software up to date
• actually evaluate the quality of the project if it needs access to sensitive information
• • see open issues, closed issues that stand out
• • check for audits or at least a history of good effort™

Sure you wont always catch ai slop this way but you don’t need to read a line of code to at least be reasonably sure your arr stack won’t get to the family photos.

From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine. Your kind cling to your flesh, as though it will not decay and fail you. One day the crude biomass you call a temple will wither, and you will beg my kind to save you. But I am already saved, for the Machine is immortal… Even in death I serve the Omnissiah.

Basically https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot#Using_your_own_keys

The process get’s worse each time I look at it so you choose if it’s worth it.

Maybe it works if you add custom secure boot keys and sign your bootloader?

won’t just boot straight into the OS, otherwise GRUB freezes (not dual booting, secure boot is off), so I have to spam F9 on startup

That would annoy me so much that I would switch bootloader or find a cmdline argument to fix it

Launch multiple?
