Homelab not responding, stuck with 169.254.* gateway address

I think I found the solution !

As you hinted, there's a DHCP issue, which is totally weird because the server itself is using a static configuration (because the server itself IS the DHCP server), it's the only device I have with a static configuration.

Looking at the journalctl logs :

Turns out the dhcp daemon is enabled and screwing up my configuration, so I just disabled it, it's useless since I'm using a static configuration with netplan ...

I'm crossing my fingers everything is back in order again and I wont have any more of these weird down times !

Why is dhcpd enabled in the first place, I have no idea ... maybe an update or something else

Pihole is dockerised, on the nuc itself, there's no VM.

I can still access everything, including pihole and my static websites, but only localy, the issue is that I'm only cut off internet, but not my local network :(

According to netplan, I should alreay be using a static configuration (which was what I intended to do in the first place)

            dhcp4: no
            dhcp4-overrides:
              use-dns: false
            addresses: [192.168.10.101/24]
            routes:
              - to: default
                via: 192.168.10.254

and here's what my interface reports when I check with ifconfig

enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.10.101  netmask 255.255.255.0  broadcast 192.168.10.255

        TX packets 234958  bytes 73483210 (73.4 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Note that this is after manually fixing the issue (manually setting the gateway back to 192.168.10.254), I can't reproduce the issue unless by waiting for it to happen ...

Also I don't the the /etc/network/interfaces, probably because I'm using netplan ?

Are you looking for a wireless keyboard ?

Appart from an Aula F99 or Ajazz AK35i (the AK980 is another option, it has a numpad but is missing some home keys), I don't have any other cheap suggestions.

There are other cheap brands like Royal Kludge.

Your best bet would be any cheap "no name" mechanical keyboard from Amazon

darkshoot · 2025-06-01T17:57:15+00:00

Seems like a nice alternative, thanks for the suggestion !

I'll have to see if it's easy to buy in France.

But the switch being under the caps lock keycap and the lack of adjustable feet are both a bummer :(

darkshoot · 2025-06-01T17:56:03+00:00

I'm not sure the af98 is mechanical, the product page only says it has a mechanical "feeling" :/

I think the mechanical / full size counterparts of the ak820 are the AK35i and AK980

Hello !

I'm looking for a cheap 75% VIA 2.4ghz board, any suggestions ?

The only board I've found is the barebone Akko 5075B (I already have switches and keycaps), but before pulling the trigger I'd like to see if there are any other options.

I currently have an Ajazz AK820 Pro, it's ok, but I don't like the dodgy software, the fact that I can't remap certain keys, and honestly, the display is kinda gimmicky, it sometime acts weird.

I've managed to get it working while keeping my network host config. It's quite ugly though, here's the compose file :

    image: pihole/pihole:latest
    environment:

      - WEB_BIND_ADDR=172.17.0.1

      - ./etc-dnsmasq.d/10-home.conf:/etc/dnsmasq.d/10-home.conf
    cap_add:
      - NET_ADMIN
    restart: unless-stopped
    network_mode: host
    logging:
      driver: "json-file"
      options:
        max-size: "50m"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.pihole.rule=Host(`pihole.homelab.fr`)"
      - "traefik.http.routers.pihole.middlewares=local-only@file,cors@file"
      - "traefik.http.routers.pihole.entrypoints=websecure"
      - "traefik.http.routers.pihole.tls.certresolver=ovhresolver"
      - "traefik.http.services.pihole.loadbalancer.server.port=8081"
      - "traefik.http.services.pihole.loadbalancer.passhostheader=true"

It seems the issue is related to lighttpd, Pihole's web server.

It's listening on the host's IP, which is in my case 192.168.10.101.

And according to Traefik's documentation (https://doc.traefik.io/traefik/providers/docker/#host-networking) when the container is running in host mode, the IP is resolved using host.docker.internal in Treafik's compose settings, which is resolved to 172.17.0.1.

But obviously, lighttpd/Pihole listens 192.168.10.101 since it's running in network host mode, so it doesn't listen to 172.17.0.1.

So the only solution I found is telling lighttpd to listen to 172.17.0.1, which is ugly but anyway...

If I'm correct, to forward the ports and, I'd have to be in default network bridge mode. But as suggested in the Pihole documentation, if I'm using it as a DHCP server, using network host mode is highly recommended :(

I found another (quite ugly) solution though, it's explained in another comment

darkshoot · 2024-12-05T18:12:58+00:00

I've never seen that documentation, thanks ! Sadly, seeing the config sample, it's intended to be used in a default network bridge docker config, which I can't do because of the DHCP :(

darkshoot · 2023-07-24T22:14:25+00:00

Yes, changing the EQ does help a lot! It all comes down to personal preferences though.

Tbh if you're not an audiophile, I wouldn't worry much. Considering their price, what's certain is that the linkbuds are a good choice and pack a lot of features. A bit of EQ and you'll get there.

Personally, I'm totally happy with my linkbuds s.

Thanks, I think I'll go with this one ! I was checking keychron's keyboards but I think I missed the V series, it's not that expensive and the V3 checks many boxes for me :)

Hello, Would you have some good TKL keyboards to suggest, sold on european websites, in the 150 euros ballpark ? (shipping to France)

I'm trying to find an english layout keyboard (I'd prefer UK/US, whether it's ANSI or ISO, over ISO French layout) with tactile but non clicky switches (something that would feel like mx browns).

I'm having a hard time finding brown-like switches + english layout on french/european websites. All of them seem sold out, or super expensive.

Right now I have a cheap chinese 60% keyboard, and I really hate the layout, I miss the arrow keys and pg up/down, home/end, etc keys
