firejail VS hosts

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?

Not by default but a blocklist can be found here https://github.com/StevenBlack/hosts

While it is now unblocked, the Steven Black list has been blocking a lot of innocent CDNs.

How does this compare to using a hosts file with known ad servers?

like: https://github.com/StevenBlack/hosts

I use the Hosts file to block a ton of ads and that works really well. https://github.com/StevenBlack/hosts Something worth considering if your ad blocker isn't working well.

The no-tracking project used by RaspAP is shutting down, so we took the opportunity to search for open source blocklist alternatives. Among the best is Steven Black's hosts list: https://github.com/StevenBlack/hosts

No idea, api.radar.io is on the block list since January 2020.

The commit's comment is "major update from adaway.org"

You can also use a declarative adblocker like uBlock Origin Lite [1], which only provides the browser with a list of elements to filter, but doesn't have any permissions to read content or perform requests. Or simply use your hosts file to apply OS-wide filtering with no browser add-ons needed: https://github.com/StevenBlack/hosts

Be aware that if you use these "passive" blocking methods, there are some sites like YouTube where you will see ads, because in these cases it's necessary to actually manipulate page content to hide them. What you can do is use a traditional adblocker but enable it only for these few sites where the declarative approach is not enough, take a look at [2] for more details.

When I select my custom hosts file, it basically breaks internet. However, if I choose a custom hosts file that is a copy of the dev's default, or if I just add a few lines to it, it will work. If I add too many lines, or use a different hosts file altogether (like the ones recommended by the dev), all connectivity breaks. Of course the latest official LetMeBlock is installed and mDNSResponder killed/restarted. I'm using Dopamine on A12+.
