Rate-limiting 10.0.2.100 #124

Closed kostadinnm closed 2 years ago

kostadinnm commented 2 years ago

Hello. I've been utilizing the single-container setup at home. It's all in a podman container on an an almalinux(centos-based) homelab box. On my personal laptop I've just tried to restore a couple of docker containers, which auto-pulls some images and I started getting timout errors stating 60 seconds are exceeded. I understand that pi-hole had enabled rate limiting for a while now. The question is shouldn't the pihole instance be excluded from this limitation and not change the limit for all the nodes in my network?! As I am a power user, I might bump the limit, but how should I know how many requests is my use case making?! Here's some of the ftl log and it doesn't state the exact query exceed number:

I've connected to a hotspot and downloaded most of the stuff(uncached dns-records, I guess) and it's ok now, but still this might be helpful to someone.

Cheers, Kostadin

I think there might have been an (cross-) issue with my workstation machine and pi-hole itself. My work containers were re-launched with the latest images, but I continued to experience laggy execution of ping requests to arbitrary domains. This had been noticable in general internet browsing as well. Directly pining resolved ips was fast and flawless. I am closing this, as it may actually not be relavant here and I got it working for me without any modifications since. If it happens again, I'll try gather more context and probably report back(here or over to pihole/unbound ground).
