Huh. I had a conversation with a Tor developer on this topic about a decade ago, when network namespaces were still kind of a new hotness - the feedback I got was that it would be an easy way for people to think they were being secure while still leaking a bunch of identifiable information, so I didn't push that any further.

I think the tor folks made a fundamental strategic error by pushing that line. Yes, people who face a serious threat need to use tor browser and still pay attention to other ways to leak etc. But if we'd got 'tor everywhere' it would still make mass surveillance a lot harder. For one thing, today mass surveillance can detect who is using tor. If everyone was using it that wouldn't matter.

Strange, because torsock and torify do the same thing, but less robustly.
gobip · 32m ago
When you have torsocks or torify for everything, you're gonna leave your footprint through tor, whereas something like Tor Browser is designed specifically not to leave any print on the web.
Using tor directly on the kernel level means that your DNS is gonna leak. Your OS telemetry is gonna leak etc.
It's still a good idea but it should be implemented top to bottom and nothing left in between, otherwise you're de-anonymized quickly.

Oniux seems like an "officially" supported tool similar to orjail (which hasn't received a commit in four years, but still works great as a shell script with iptables/iproute tools [1]). Orjail has also an option to run with firejail for further isolation, which seems to be still a feature that Oniux doesn't have.
Isn't all this reserved to TCP, in other words in which way may it protect non-TCP activity?
charcircuit · 6h ago
Non-TCP activity wouldn't route and will fail to send.

Note that you can use the Tor daemon as a normal DNS via UDP server and it will resolve your DNS requests over the network for you.
Maybe I'm wrong, but it seems similar to I2P where if you want "UDP", you'd need bespoke plugins/transports/whatever for each application.

Thank you, therefore my first impression seems right: without any provision for UDP this isn't an easy-to-setup and transparent way for any user to preserve his/her privacy.
HappMacDonald · 1h ago
As always this will depend on your definition for "any user".
Users who try to do a lot of UDP traffic will have to change their habits, yes. But a majority of users who don't know a lot about computers rarely do anything on a PC that isn't driven by the browser anyway.
But at least the users who try to use UDP won't wind up specifically leaking info, just wind up slightly confused why certain things aren't working.

The TOR protocol does not natively support UDP, though there are workarounds[0]
Does this mean one can now access tor websites using chrome?
kyguy23 · 6h ago
You can, but please don’t do this, you’ll stick out even more! Tor browser has a series of anti fingerprinting strategies that chrome doesn’t
OsrsNeedsf2P · 6h ago
Does Brave attempt to mimic any of these anti fingerprinting strategies? Asking because it has a "Private tab with Tor" feature
fatchan · 5h ago
No. First of all, just check for `navigator.brave`. If it exists, it's Brave. When I ran a .onion site I added a JavaScript check and if navigator.brave was present, it redirected users to a specific page saying:
> Hey, there's something funny about your Tor Browser. When browsing Tor hidden services (.onion), you should be using Tor Browser. Are you using an outdated version, or perhaps something else entirely?
Brave is chrome. Tor browser is firefox, has a bunch of tweaks, different default settings, and a different fingerprint. Also when browsing on Tor, you should disable JavaScript as it's a source of many vulnerabilities.

The main strategy is that most people on Tor are using Tor Browser. This creates a cluster big enough to blend in. If you're using anything else, you're sticking out.

You always could by just setting the proxy environment variables (or in settings). The standard port for the tor daemon is 9050.
In fact, it's relatively easy to write a socks proxy that lets you route traffic through a arbitrary protocols. For example, I can serve/visit websites on syncthing with a socks5 proxy as a translation layer: https://github.com/acheong08/syndicate

Chrome has zero user-facing proxy controls of its own on Windows, nor PAC support. But the --proxy-server command line argument works.

They use hexchat as an example but do these processes run with the users configuration? Wouldn't this leak IRC usernames if you forget to change it.
... Or leak cookies if you launch a browser?

Separation of concerns - although Tor goes to great lengths to prevent fingerprinting, Tor and Oniux’s main aim IMHO is to make the source IP untraceable.
Same thing could have been said about using Tor to login to Gmail (if it were not HTTPS).

What do you mean by leak usernames? It would leaks that a username uses tor. It would still leak that all of the usernames connecting to the same IRC host would be the same person.
IRC seems pretty dangerous if you want to remaining anonymous considering how many people are logging disconnection times allowing them to be correlated with other network disruption events.

Irssi iirc used to default your username to your system username, so noobs would leak their given name by accident. After seeing that I changed my username in Linux to always be the most common username

root?
SV_BubbleTime · 8h ago
What is the most common Linux username though? Obviously you don’t want to do your regular work as root. And guest has its own issues.
Is there a “common name”?
