Pi-hole

Hello, I need to install pi-hole on gentoo.
RPI 4 1024MB RAM freezes, ddns stops working, and that's not acceptable. I don't want to install the ubuntu virtual machine from pihole.

Can anyone help install Pi-hole on gentoo?
At this link -> https://discourse.pi-hole.net/t/add-gentoo-as-a-supported-os/2011 ,
somebody added support for gentoo. Unfortunately, the patches are not up to date. Please help.

There is no Pi-Hole ebuild in portage or in any of the listed overlays. What is it you're aiming for? I have pretty much the same with a script in a cron job and dnsmasq.

What my script does is pulling in a host list from here: https://github.com/StevenBlack/hosts
Then i use a number of sed lines to remove stuff i don't want to be blocked (there is some MS stuff and image boards blocked there).
In the end it adds a few other domains that i miss.

So this runs once every few days and apart from the shiny interface, it should be exactly the same.

It might also be possible to use Unbound for this.

there's one way that does work well to install pi-hole on gentoo and that's using docker. There's an official docker image for pi-hole. I've been attempting to set it up on my own server today but i'm still a docker novice.

1GB of ram may be a limiting factor but it may just work.

default/linux/amd64/17.1/hardened/selinux (stable) *
I use my gentoo as a home router and server. I have xfce4 graphical environment installed in it. Do you recommend turning off selinux?
I thought selinux was configured incorrectly. I use this gentoo profile for the first time, I have been working on desktop more often.

isn't the entire project just a blacklist of hosts.conf? i never actually took a look at this, but I will. tomorrow. too much request.

pi hole's dnsmasq service cannot start if there's a dns service or listener active on the host system. Just learning docker this appears to be one of the flaws of using docker but i'm still learning.

I did find this guide that could be useful reference perspective.

How to properly launch the docker and pihole container in autostart after restarting the system?
I tried the script https://github.com/0x17de/dockerservice-openrc and the docker start -a pihole command after rebooting from the file https://github.com/pi-hole/docker-pi-hole/blob/master/pihole.service but it didn't work.
Only the manual "docker-compose up" in "docker-compose down" command works.

It crashed. I turned off the docker and I'm using pihole on rpi4. I have reduced the list of blocked hosts.

Yeah. It's basically like 5-6 lists of blocked domains and a nice gui. it uses dnsmasq and lighttpd for these tasks. Shouldn't be too hard to port to gentoo. I ended up using a debian VM for it and i'm pretty happy with it.

Especially for mobile devices. Those pesky annoying ads that you see in both apple and android devices are just gone. Meanwhile it uses next to zero resources to block around 10-20% of all stuff which turns out to be ads.

adblock plus, I took a look at it; it's also a list. but not domains, but urls. and not only urls, even div ids and other stuff. pretty smart actually. short but powerful lists. in some sense, adblock plus operates as a text parser/filter. it sees some links/strings and basically neutralize them. turns them to nothing. that is, before the browser renders the page. same thing can or could theoretically be done with a web proxy. squid has a thing very similar. I don't know if you could use the same lists.

pihole on the other hand, operates as a dns server. it is a dns server. it doesn't host anything, no domains, but answers dns queries. also has lists, of domains where only ads are hosted. a query comes, if it's ads on the list, send to 127.0.0.1, if not, forward query to the real dns. that's all it does. doesn't sniff traffic, doesn't look at traffic. or content. if someone is bad, then pihole will say he is 127.0.0.1. if not... forward.

I know this post is 2 year old, but now an ebuild is available in the tatsh-overlay. However, I was not able to make it run using this overlay. I'm able to make it run using docker, but I'm a newbie using docker, and I have to configure it each time I start it. Does other gentooer are interrested by using pihole on gentoo? Maybe we can share our tips and config.
