Re: Raspberry Pi and Tor Project

Mon Dec 19, 2011 3:10 am

I downloaded Tor today to play around with it (and in anticipation of SOPA?). It\'s a very interesting idea, and apparently it has been very useful in the Arab spring movement.

I got to thinking that I should support the Tor project by helping them expand their network. I attend a university with a fantastic network (<10ms ping and 120/80mbps speeds). I was wondering if it would be a good idea to try and set up an R.Pi with an arm build of Tor as a relay for the network.

What say you?

I love the idea. Was wondering if the local free internet hotspots could help out unknowingly as well if a few PIs happeneded to be left near them...

TOR is almost certainly going to get you in trouble. TOR is used for many nefarious purposes as well and that traffic will look like it\'s coming from you.

University networks aren\'t the anything-goes networks of the 90s anymore. Look up your responsibilities and network restrictions before adding your node to the TOR network, especially when you make it an exit node. I\'m not saying don\'t do it, just know what you\'re getting into and what you can do to limit your exposure. Work with your network admins, not against them.

I was a exit node for a few days.

1) I am blocked from wikipedia.

2) I am banned from many IRC servers

3) I have to enter captchas to search Google.

4) I\'m lucky that the police didn\'t knock on my doors for distributing child porn.

Hmm... those are strong points. If you\'re not an exit node would you still get banned from anywhere with a moderator?

I\'ll look into my university policies.

EDIT: Not allowed. They prohibit any form of server on the network, for things like IRC and games. I\'m sure Tor would fall under this category. To hell with it though, I can use their guest (unidentified) network and they can\'t trace me.

It\'s all a matter of whether it is worth the effort.
1. Is it worth your effort to go encryption, etc... (to a degree, yes... but what degree?)
2. Is it worth your network admin\'s effort to track you down? ( Hint: large amounts of encrypted data from a (semi) static address = easy to identify. ) So it depends on what you\'re doing with your traffic...

They may come looking just because of the encryption, but that\'s less likely unless there\'s a significant amount.

I don\'t think using it off batteries and wifi in a public place (library/cafeteria) would be easily traceable. In all seriousness though I don\'t think I will. I wouldn\'t want IPs in the university blocked from wikipedia...

Well, to help the TOR project it is not a requirement that you operate an exit node. You can donate your services/bandwidth as an entry node or a relay.
Whilst the existence of a service like TOR that provides anonymity does attract those that want anonymity for nefarious reasons, I think that it is fair to say that repressive regimes really hate the TOR network as it punches holes in their state propaganda machine, and allows communication between the inside and outside of their network of control.

Conspiracy theorists may consider that obnoxious content transmitted through TOR may, in some part, originate from the regimes that wish to see web anonymity's demise. (?)

The Google corporation seem to hate TOR too: They certainly seem to prevent use of their search engine from exit nodes. I think it is because it spoils their data model for collection of information about individual users' behavior online.

Search engines like StartPage are friendly to TOR usage.

I personally think the the freedom to say what you think without having to publish who you are, is actually a cornerstone of democracy i.e. the secret ballot.

Certainly, before you set up a TOR exit node, you should understand the risks involved, but it's not the only way to contribute to TOR. 8-)

You'd be doing the world a favour.

Ahh TOR, an innocent technology but widely used by assorted n'er do wells and conspiracy theorists alike. The "man" appears to like blaming those on the outside (aka exit nodes) for what traverses the inside (like kiddy porn) http://www.bbc.co.uk/news/technology-20554788 . Just make sure you're on the inside and you don't keep logs.......

Please note, this is the opinion of the poster, I do not run a TOR node (or ever have done) and I am not (or ever have been) involved in child pornography. I'm just a geek who understands the technology and the perceived need and uses for such technology.
