firejail VS Pi-hole

bubblewrap is designed as a low-level too. There is nothing quick and dirty about it. It disallows everything by default and you have to be explicit about what you want to share with the host. If your application needs complex permissions/resources, then you will need to have a complex bubblewrap command line.

Once you have figured out which permissions/resources you need for a given program, you can wrap the command line invocation in a shell script.

If you want other people to do the work of defining permissions/resources, then have a look at firejail: https://github.com/netblue30/firejail

Firejail is cool: https://github.com/netblue30/firejail

Linux namespaces/cgroups but nowhere near as heavy as Docker.

I use it when I want to limit the memory of a Python script:

```

Firejail can also be a useful option, though no good if you're on Mac https://firejail.wordpress.com/

Uses the same Linux primitives as docker etc, but can be a bit more ergonomic for this use case

Firejail, Flatpak (which uses Bubblewrap under the hood), and Snap (which uses AppArmor) all use the same underlying technology: Linux namespaces.

This question comes up a lot, and has been answered here: https://github.com/netblue30/firejail/wiki/Frequently-Asked-...

TL;DR: Firejail has much more comprehensive features than Flatpak (Bubblewrap). Firejail also has more comprehensive network support, support for AppArmor and SELinux, and easier seccomp filtering.

Compared to Snap (which uses AppArmor), Firejail is compatible with AppArmor and again goes above and beyond with a lot of additional features.

Wonderful little tool, too bad you must chain various exec calling tools to get cgroups (a bit akin to `ionice ... nice ... cmd`) and Linux users namespaces can't allow UNIX sockets while preventing network access (I think?).

Migrated from Firejail when its complexity annoyed me too much and I hit https://github.com/netblue30/firejail/issues/3001 (Firejail doesn't like parens or brackets in --put/--get parameters) to a badly NIH version using bwrap and bash to have "profiles":

Firejail does this. The profile database is the two "profile" directories in https://github.com/netblue30/firejail/tree/master/etc

What do you mean by a Firefox container? Do you mean FireJail?

Si te preguntas, ¿por qué no usar Adguard o Pihole? 🤔

This is an overreaction, almost to the point of absurdity.

Risks inherent to pipe installers are well understood by many. Using your logic, we should abandon Homebrew [1] (>38k stars on GitHub), PiHole [2] (>46k stars on GitHub), Chef [3], RVM [4], and countless other open source projects that use one-step automated installers (by piping to bash).

A more reasonable response would be to coordinate with the developers to update the docs to provide alternative installation methods, rather than throwing the baby out with the bathwater.

Pi-hole to block ads and tracking for my less technically savvy relatives

I ran a competing project[0] on my home network for a few years before I discovered NextDNS[1]. What I lost in performance (requests don't leave my house) I gained in portability: ALL my devices can take advantage – at home and away – and time-saved. PiHole works 90% of the time, but when it did stop working, I'd have to spend a bit of time fixing it. At $20/year, I simply couldn't compete with NextDNS.

Note: This isn't a shill for NextDNS; I love these kinds of projects and think they absolutely should exist, but NextDNS just happens to be one of those dead-simple SaaS tools that is an insanely good value.

It definitely IS an option, but at the network level.

It runs on damn near everything, and is a DNS level adblocker for the whole network.

I recently switched to Wipr [0]. It’s dead simple to use, and will auto update its filter lists in the background.

Adguard [1] is a decent free option.

I also use a Pi-hole [2] on my network.

Are you trying to build a DNS proxy (similar to Pi-hole) that intercepts DNS requests and checks for the ones that look harmful? If so, I would suggest trying to separately build a DNS client and a DNS server, before trying to integrate them together. Start with Beej's Guide to Network Programming if you need to learn the basics of sockets, and then take a look at the documents that define the DNS protocol itself (RFC1034 and RFC1035).

Setup a pi-hole.

It's definitely not as simple as installing an app on your phone, but I run a Pi-hole on my home network, and it does block ads in many games.
