Rate limiting of a hidden service
by Evan d'Entremont 30 Sep '15

30 Sep '15

I developed a scheme to rate limit hidden services using proof-of-work; https://gist.github.com/evandentremont/a3ad12a5cc3a924dae34 The server sends a semi-prime to the client, which then factors it. The client submits the factored primes back with the next request. The 'rate' can be throttled by sending a larger or smaller semiprime. The client has to spend time factoring that number, and the request can simply be dropped if the factored primes aren't correct. It would be effective to hinder brute force attacks on a login screen at the very least. Running as a script on the page isn't ideal as a lot of people disable javascript. There's always the option for a fallback where you calculate the primes yourself and submit them, but I feel like it would be better implemented as part of tor itself. Just throwing this out there for thoughts / feedback / opinions on rate-limiting hidden services.

Second release of OnioNS beta
by Jesse V 29 Sep '15

29 Sep '15

Hello everyone, I am pleased to announce the second release of the Onion Name System (OnioNS) for beta testing. This release represents about 180 commits and is a major update from my last release. The two servers should be up long-term, so feel free to play around with it. "Example.tor" is live and new registrations should be available client-side about 20 seconds after upload. As usual, the code, pre-built binaries, and instructions are available in the four OnioNS repositories at https://github.com/Jesse-V?tab=repositories Please star them if they work well for you. Most people will probably just want OnioNS-client, which integrates into the Tor Browser. The big changes include: * Servers are now powered by hidden services. This means that they utilize existing Tor connections (circuits and TLS links) which is a major improvement over the direct communication in the last release. In the process, I switched all communications from SOCKS4 to SOCKS5 and it seems to work well. The OnioNS servers would be excellent candidates for single-onion services (Tor-embedded servers with only client-side anonymity) so I will switch to that when they becomes available. * Servers now manage Ed25519 keys and I'm using floodberry's ed25519-donna implementation. All responses from a server are signed, so communication is automatically authenticated. The private key is held in the main working directory, which is ~/.OnioNS/ for the time being. Due to this, it's not currently possible to run two distinct servers as the same user. * The trusted Quorum server now generates a Merkle tree and signs the root, which the client uses to authenticate Records (registrations) and to provide authenticated denial-of-existence. In effect, this prevents the client's name server from falsely returning a 404 or from forging a Record. * I overhauled most of the networking code. It's significantly more stable, closely follows a request-response pattern, and I don't anticipate needing to change the networking format in the near future. * The hidden service software now saves the generated Record to disk, so that it can try again if the upload fails. * I introduced two static analysis tools: cppcheck and Clang's scan-build and created the scanBuild.sh script to facilitate analysis. They found one small memory leak, which I fixed, so now all of the repositories pass inspection. * I'm now using the Travis continual integration system, which watches for commits in Github and then rebuilds the project. I get notifications in #tor-bots if the repo fails to build into a .deb, which is handy. Any pull requests are also checked in the same way. * Many bugs were identified and fixed. I need some help with: * Testing a linking bug that is sometimes encountered when compiling from source. The ticket is https://github.com/Jesse-V/OnioNS-server/issues/79 I don't know whether the issue is dependent on Debian Wheezy, Ubuntu Trusty, or my CMakeLists. I'm not sure how to fix it, either. * Testing an experimental .rpm format. I used the "alien" program to convert Wheezy and Trusty .deb files to .rpm, so as to better cater to Fedora. The rpm's are available in the Releases page on Github. I don't know if the packages work correctly, so if you are on Fedora, please try them out and let me know. If they don't work, I would appreciate instructions on how to build them properly. * General testing: does the HS-side and client-side code work well and perform reliable for you? Related notes: * Earlier this month someone in Egypt created the ".tor" article on Wikipedia, which has a few details about this project. Thanks for that! * S7r, I couldn't contact you on IRC, but if you're still up for running a name server to handle client connections, please let me know. I'll need your HS address and your server's Ed25519 public key, which is shown when the server starts. Then I'll push out an update that should transition clients over to you. It'll be nice to spread out ownership of the infrastructure. Next on the list: * I'm planning to focus the next release on stability, security, unit tests (I'm looking into coveralls.io), and doxygen documentation. The code is currently a bit fragile, so I'd like the next release to improve error handling. I'll be maintaining this version until the next one comes out, so I made a "stable" branch which will be for bug fixes and the like. I recommend that Ubuntu/Mint users use the PPA so that it's easy to deploy updates. * I need to let servers update themselves if they are out-of-date. Once I fix this, it should be straightforward to add more servers to this system. Thanks for the support everyone, and enjoy testing! Jesse V.

Proposal: Merging Hidden Service Directories and Introduction Points
by John Brooks 29 Sep '15

29 Sep '15

Hello! George and I, along with the other participants of this hidden services meeting, have written a proposal for the idea to merge hidden service directories and introduction points into the same entity along with proposal 224. Comments are encouraged, especially if there are downsides or side effects that we haven’t written about yet, or that you have a different opinion on. The intent is that we can decide to do this before implementing proposal 224, so they can be implemented together. The proposal is attached, and also available from: https://raw.githubusercontent.com/special/torspec/224-no-hsdir/proposals/id… Thanks! - John

I am very interested in seeing it become a more general-purpose method for externalizing DNS handling. I2P has supported pluggable NamingServices for a long time, and it is trivial to add new methods. Now that Tor is considering them, I would like to see whatever protocol is decided on standardized in some way, so that GNS, Namecoin etc. can implement one protocol and be interoperable with both Tor and I2P. I include some comments below to this effect. I would expect that if this went ahead, this spec would be split into a) a general spec for the RPC protocol, and b) how Tor itself uses the protocol. > > > Filename: xxx-special-use-tld-support.txt Title: Special-Use TLD > Support Author: Jeffrey Burdges Created: ??

This is not a domain name-like value, like foo.onion or bar.b32.i2p, so the ability for the returned record to support these kinds of return values should be considered. If a domain name-like value is required, then I2P would need to do two lookups - one for spam.gnu -> bar.b32.i2p, and then a second (internal) for bar.b32.i2p -> DESTINATION. This partly also depends on what kind of records the external service supports, but IMHO the RPC protocol should not be limiting in this regard, given that it will likely only be used by networks like Tor and I2P that cater to more than IPv4 and IPv6. > > Sepcial-use tLD suppliers should internally process CNAME records "Sepcial" -> "Special" > that fall into their own domains, but they should return CNAME > records to Tor that refer to .onion or .exit domains, or to normal > DNS names.

One thing that the I2P NamingService impl doesn't do is recursive lookups, because we haven't had a need for them yet (we instead have an optional fallback system where if a lookup fails with one configured service, it can try another one). But it wouldn't be hard to implement, and I agree with having the RPC user handle CNAME records instead of the external service. str4d > > Variations > > Tor would conceivably benefit from externalizing its own DNS > handling as a separate process.

Simplifying load balancing by removing Guard+Exit?
by Mike Perry 28 Sep '15

28 Sep '15

Hey all, I am playing with the load balancing equations in 3.8.3 in dir-spec.txt (https://gitweb.torproject.org/torspec.git/tree//dir-spec.txt#n2454) in order to account for padding, hidden/onion services, and directory traffic, and I've noticed that the fact that nodes can be both Exits and Guards not only vastly complicates the current equations, but will make any attempt at accounting for this additional overhead nearly impossible. If you've previously tried to understand the current load balancing equations, or wondered why they have 3 major sub-cases and roughly 9 sub-cases, this is entirely to account for Guard+Exit nodes, and to handle relative scarcity of pure Guard and pure Exit nodes in various conditions. Removing the Guard+Exit ('D') nodes makes all of those cases condense to one single, simple set of solutions: ⎧ E + G + M E + G + M 2⋅E - M - G 2⋅G - M - E ⎫ ⎨Wee: ─────────, Wgg: ─────────, Wme: ───────────, Wmg: ────────────⎬ ⎩ 3⋅E 3⋅G 3⋅E 3⋅G ⎭ No missing constraints, no sub-cases, no boundary conditions. Easy to reason about. Easy to intuitively convince yourself that the solutions are correct. What I want to do is add two variables to the consensus that allow us to specify expected (or measured) overhead at Guard nodes (G_o) and at Middle nodes (M_o). These two variables would represent the sum of padding, directory overhead, and hidden service traffic experienced by Guard and Middle nodes, respectively. If we ignore Guard+Exit nodes, this makes the load balancing equations become: (1-G_o)*Wgg*G == (1-M_o)*(M + Wme*E + Wmg*G) # Guard bw == middle bw (1-G_o)*Wgg*G == Wee*E # Guard bw == exit bw Wmg*G + Wgg*G == G # Guards can be middles or Guards Wme*E + Wee*E == E # Exits can be middles or Exits These solutions are a bit longer so I won't paste them here, but they are still reasonable if we ditch the Guard+Exit idea. They can be simplified even further by using a similar approach as the GuardFraction idea from Proposal 236 (Section 1.3): We can simply adjust each Guard's bandwidth by G_o either before solving the equations, or by adjusting Wgg and Wmg after the solution, then we only need to include the (1-M_o) factor in the equations themselves. We can't really do this simplification if we keep Guard+Exit, because of the interplay between Exit and Guard weights in the system of equations and cases. Additionally, if we keep Guard+Exit, the solutions literally consume an entire page of text to represent symbolically, and the sub-cases become even more complicated to evaluate and check for proper bounds and correctness. In fact, George has already run into such edge cases while trying to implement Proposal 236 (See https://trac.torproject.org/projects/tor/ticket/16255) Moreover, I've been thinking about the surveillance incentives for Guard+Exit nodes, and I actually think it is a net risk to the network for nodes to be both Guards and Exits. It's easy to find an excuse to watch an Exit node. If anything bad ever happens from an Exit, you may be able to convince someone to let you keep an eye on it** "just in case". A Guard-only node shouldn't cause anybody any problems, though, and should be much harder to justify monitoring. So this means that Guard+Exit nodes allow an adversary to justify monitoring large portions of both the entry and exit traffic of the network without any strange/technical/esoteric arguments about the need to perform complicated statistical attacks with questionable accuracy and high collateral damage, and instead force them to justify their monitoring another way. I also hear from large node operators that it is still the Exit flag that causes their nodes to really become overloaded, so if that's actually true, then it's likely that Exit nodes make poor Guards anyway, especially if Exit bandwidth is scarce (which it often is). So, what do people think? Does anyone violently disagree with removing the Guard flag from Guard+Exit nodes? ** I used to run an Exit node, and my lawyer at the time was told exactly this at one point during a police visit about a nonsensical bomb threat to some 4chan equivalent. He was specifically told "We will be monitoring this node from now on" by one of the visiting officers. I was unable to ever discover what that actually meant, and the EFF unfortunately did not feel it was worth pursuing to help me find out. It may have been a scare tactic, but it could just as easily have not been, and for all I know they may have been actually able to convince a judge to let them do this. -- Mike Perry

Two new Onionoo versions 2.4 and 2.5 add new "effective_family" and "measured" fields
by Karsten Loesing 27 Sep '15

27 Sep '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi devs, I was reminded by Harmony that I said a while back [0] that I would announce new Onionoo versions on this list and not only in private message to Harmony for including them in the next TWN issue. Oops. So, version 2.4 added a new "effective_family" field to details documents, listing all the relays with which the relay in question is in an effective, mutual family relationship. The main goal here is to make it easier to detect misconfigured relay families. This can be relay operators or friendly people watching over the Tor network and reminding relay operators to fix their configurations. [1] The new version 2.5 that I deployed this week adds the optional "measured" field to details documents. The main idea behind this new field is that relay operators and Tor network debuggers can now figure out easily whether a relay is affected by not being measured by a sufficient number of bandwidth authorities and as a result has lower usage than it could handle. This field is not yet displayed by the Onionoo clients Atlas or Globe, but it's accessible via Onionoo's API [2]. More details are on ticket #16020 [3]. All the best, Karsten [0] onionoo-announce@ posting from April 27, 2015 [1] https://lists.torproject.org/pipermail/tor-news/2015-August/000109.html [2] https://onionoo.torproject.org/protocol.html#details [3] https://trac.torproject.org/projects/tor/ticket/16020 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org iQEcBAEBAgAGBQJV1HYeAAoJEJD5dJfVqbCrFJAIAIQYIC0CiSx6GJJikQ6CTxgw +AljFxABfnLtHu58EtBLx1jRJo0u9fStCMA/YFWLiq3FmEhCb5YvoL4zwa92PwlN bIoEricgq3sXjOm6TxJ75/6OBeH8AVIsah6qxHFkVfCPwjmt0bsDyaE7VqlCv2tN tAunIZcDyhsStGOOErr5uc9FHgPquvb66Iy7YFwnJxioMRE3yp4GBTDv78WyUEuR TZOWBh/cbJYrwSu5b+vU3C+t9eAI9ErQ8BDYlwy0C6zgJO+paSUkxWkCvuI3nv2l e/Ol6M40c9syZEb5jexn3K3NTOpJCKKhjXoXtP7UHXz8ZSdhZw2gxi31ZXYrSkQ= =/rwg -----END PGP SIGNATURE-----

Tor on iOS 9
by Conrad Kramer 27 Sep '15

27 Sep '15

Hi all! I'm new to the list, my name is Conrad. As some of you may or may not have heard, Apple's latest version of iOS enables functionality that allows for a system-wide Tor client. A few people in the community, myself included, started working on a project to get this client into the App Store. I wrote up a small document (attached) that explains the project in detail, so that you can learn about it if you're interested! I'm very excited to get Tor into the hands of many more users. Conrad
