[tor-talk] Announce: Tails 0.7 is out
Hi, Tails, aka.

Last time I tried, combining Tor + sftp mounted by GNOME's "Connect to server" worked quite well. Inserting transparent encryption into the loop was a failure (very poor robustness, much too frequent disconnects), but I only tried gvfs-fuse + cryptkeeper (EncFS). I don't know if the root cause of the failure I faced was the slowness of Tor vs. lack of robustness of the tools, the depth of the stack, any used component or a combination thereof.

I've just had a look, by attempting to implement the same in Tails (i.e. query first the Tor resolver, and fallback to ttdnsd in case the former is not able to answer the query) as we planned to do for quite some time. I've seen the same results as you have, using the DNS frontend caching proxy Tails already ships (pdnsd) instead of unbound. A few dig commands learned me that the Tor resolver sends an empty reply (status: NOERROR, QUERY: 1, ANSWER: 0) rather than an error when it does not support the type of the query (e.g. MX). The obvious consequence of it is: the caching frontend DNS proxy (be it unbound, pdnsd or whatever) has thus no way to know it should fallback to ttdnsd in such a case, and it actually never does so, which confirms what you've observed in the first place. => In the current state of the Tor DNS resolver, we're forced to use ttdnsd by default, and only use the Tor resolver for .onion/.exit... unless I missed something. So I'm curious what the rationale for the "empty reply" behavior is. Any ideas?

However, we don't generally recommend doing that for reasons I already highlighted and pointed you at. The incremental upgrades idea I pointed you at is something entirely different, though. It's about *persistently* upgrading a system when a Tails point-release is out, while minimizing the amount of data that must be downloaded. Please explain how AUFS could be used for solving that problem, and why it would be better (size-wise, or whatever) than the stacked SquashFS idea we've been thinking of. >> I may be missing your point, but Tails is not a random collection of >> packages that could be individually upgraded without any thought. >> Tails is a carefully crafted system that aims at guaranteeing certain >> properties.

We already have a plan to fix the "Tails is read-only" side of things (see the stacked SquashFS idea I pointed you at). The main problem is that Tails is a full Live system built upon a whole autonomous world (that is, Debian repositories) that is constantly changing; again: Tails is not a random collection of packages that could be individually upgraded without any thought. Tails is a carefully crafted system that aims at guaranteeing certain properties. We do our best to ensure an ISO we ship meets a certain specification. There is simply no possible way for us to ensure the same for "that ISO plus any number of APT upgrades on top of it". Please tell me what's unclear in this paragraph. The only possible way we could propose incremental upgrades through APT would be to manage our own APT repositories, so that we entirely control the flow of packages that could flow into a given Tails system. Personally, I don't think it would be worth the effort, and I still think it makes sense to go the "incremental upgrades using stacked SquashFS" way we've been pursuing. In any case, the APT way would make bug reporting, reproducing, debugging and fixing much more complicated: currently, one runs "Tails 0.9", not "Tails 0.9 plus this and that upgrades". Also, please be kind enough to quickly sum-up what is the exact problem you are suggesting us to solve, so that other Tails developers don't need to read the whole thread to (try to) understand what the problem could be, among discussions about implementation details.

Re: [tor-talk] Designing a secure "Tor box" for safe web browsing?
Hi, Preamble: I'm still not convinced the benefits of the "Live amnesic host OS + Tor routing VM + desktop VM" approach are worth the energy we would need to move Tails to this model, but I do find it interesting to go on a bit with the thought experiment, and to explore the limits of this idea.

Obviously, you don't get the entire power of your bare metal CPU, but you don't lose that much either, and I would certainly don't feel the end result to be anything like "extremely slow". On the other hand, my experience with QEMU clearly matches the "extremely slow" results. Maybe your conclusions on VM speed are simply too tightly bound to QEMU? > There are also RAM requirements — how much do you allocate? > This needs to be decided in advance, regardless of how much memory > the user needs for performing the task in the VM. In the scenario this thread is about, I don't think it's that hard to find a way of splitting the memory that allows the user to perform their task, without being all too wasteful: * the host system's memory needs are not likely to vary much, are they? * the Tor routing VM memory needs are not likely to vary much, either * the Desktop VM gets what's left Obviously, this gets much harder for applications VM. >> I would be happy to learn why you consider this is pointless. > For tasks like abstracting network interfaces and other hardware, > the user can run everything in a VM by themselves — why force it > on everyone? These abstractions are probably the only reason why I think this approach would somehow make sense for Tails needs (even if I don't know if we will go this way in the end). This is hardly a technical question. It's obvious to me how the way you ask it, and the way I am answering, say much about how Tails and Liberté Linux differ in their approach of non-technical matters, in the ways we think our relationship to users. Let's catch this opportunity to explain my take on this a bit, and hopefully understand each other better. Note that I don't care about convincing anyone here :) So, why would it make sense to pre-configure, for everyone, the technical tools that get these abstractions up and running? Because Tails is about building a common pre-configured system that tries to address certain common needs, for anyone who happens to share these needs. (We certainly value user {self-,}education very much, as I think the recent efforts put into reorganizing and writing Tails documentation clearly displays: learning some amount of technical stuff is a must to make ones own security decisions properly. But I absolutely don't think that "learning how to choose, install and configure virtualization software, and how to setup a Tails or Liberté VM in there" belongs to the kind of knowledge that empowers people to make their own security decisions properly. I'd rather see Tails users learn things more useful than this.) Because, while people can run Tails in a VM by themselves already, doing this certainly does not give them the same benefits as an integrated, pre-configured "Live amnesic host OS + Tor routing VM + desktop VM" Tails would: * In the first case, they have to trust _their host system_ to not steal information, and to not leak anything to disk, willingly or not. * In the second case, they don't need to setup and configure that host system, because we do.

Back to the threat model, then :) One of the main Tails use-case we've heard of is to work on stuff that is public, or will become public soon: in this case, what they want to hide is not really the actual content, but instead its linkage to particular physical locations or hardware.

I'm not sure I understand correctly what you mean, but the way I understand it won't work at all in the current state of our tools. (I'd be glad to see our tools improved to support this usecase, though :) My point here is that I absolutely do not want to see a new class of users, locked in a non-upgradable, obsolete and buggy installation, coming up on our support channels, because someone gave them something called Tails, that did not really work like the real thing. So please: * Either make sure you give the Pirate Linux users a working and documented way to upgrade the Tails you are distributing to new versions we put out. Relying on "should work" feels inadequate to me. Best would be to make it so the standard, documented way somehow works for Pirate Linux users too, I guess, so that you don't have to fork the Tails documentation, the Tails upgrade notification system, and possibly more. It may boil down to contributing the changes you need to Tails, instead of having to slowly fork it. * Or, make it crystal clear to Pirate Linux users the version of Tails shipped with it "is meant to easily allow people to try Tails", and that it may be obsolete, may contain security issues fixed in Tails since then, and may be broken in various random ways. This clearly is the cheapest way to do it. In that case, perhaps synchronizing somehow with our release dates could be worth it, to avoid putting a new Pirate Linux out two weeks before the scheduled release of a Tails major version? ___ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk

Jake asked me to have another look at tlsdate, which was uploaded to Debian, so here it goes :) (It's pretty clear I lack much of the background and intended usecase, so please correct whatever is wrong in what follows!) So, Jake tells me that ChromeOS will use tlsdate by default, and that this should solve the fingerprinting issue. Therefore, I assume this implicitly answer the (half-rhetorical, I admit) question I asked in March, and I assume there is indeed some fingerprinting issue. So, in the following I'll assume it's relatively easy, for a close network adversary (say, my ISP) to detect that I'm using tlsdate. >From what I remember from our past attempts to discuss this on IRC, I assume the intended usecase for Tails is to run tlsdate in the clear (that is, without going through Tor) so that the clock is set before Tor is started. If so, from the PoV of a close network adversary, if Tails starts to use tlsdate in the clear, as a Tails user, then I'm part of the set of people who run tlsdate and start Tor soon after, and in the current state of things, this set would almost exactly match the set of Tails users. The fact that ChromeOS uses tlsdate forces this kind of adversaries to detect "tlsdate followed by Tor", instead of merely detecting tlsdate alone, in order to detect Tails users. (Looks like we have to convince Google to run Tor by default on ChromeOS? :) Therefore, I'm not convinced tlsdate in the clear would be any better, on the fingerprinting side of things, than the "htpdate in the clear" system we eventually managed to escape in Tails 0.9 and later. Which means it looks quite worse, fingerprinting-wise, than what we currently ship. Thoughts? (Seriously, please prove me wrong, my life would be easier as a result :) Cheers, -- intrigeri | GnuPG key @ https://gaffer.ptitcanardnoir.org/intrigeri/intrigeri.asc | OTR fingerprint @ https://gaffer.ptitcanardnoir.org/intrigeri/otr.asc ___ tor-talk mailing list tor-talk@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk

This means we implicitly decided it was more important to ask parties that are unlikely to cooperate to send fake time information to Tails users, than it would be to entirely avoid asking servers who generally don't care about privacy. In general, for such matters, I'd rather rely on diversity, rather than on a set of "trusted" peers. > Why doesn't tails_htp ask more than three servers for the time and > build the mediate?

[tor-talk] Please review Tails stream isolation plans
Hi, we are told that Tor 0.2.3.x is good enough for Tails, so a bunch of Tails developers have eventually spent some time thinking what could be the initial step towards basic usage of Tor stream isolation within Tails. The resulting plans are waiting to be reviewed there: https://tails.boum.org/todo/separate_Tor_streams/ While I'm at it, we wanted to ask whether it is reasonable for Tails to ship with IsolateDestAddr enabled by default (but for the web browser) as described in our plans, or if it is doomed to put too high a load on the Tor network.

The main network applications shipped in Tails, that would get IsolateDestAddr according to our plan, are: * Claws Mails (replaced with icedove / Thunderbird, some day) * Pidgin * Liferea RSS feed reader * Gobby Then you have a few command-line ones such as wget.

Since the initial question was about UX too, I feel like I should add that many Tails users don't think "UTC is fine". Quite unsurprisingly, they are confused when they are shown a clock that is off by a few hours, compared to their own idea of what time it is in their current location. It looks like *displaying* UTC for everybody is a UX failure. What would be best, IMHO, is to have UTC as the system timezone, but display local time in the {GNOME,whatever} clock applet.

[tor-talk] Which PTs shall we prioritize for inclusion in Tails?
Hi, Tails currently supports regular bridges, obfs2 and obfs3. Work is in progress to support scramblesuit. I see that Tor Browser 4.5 ships flashproxy, meek and obfs4. Assuming an ideal world in which they involve an equal amount of work, among scramblesuit, meek, flashproxy and obfs4, which ones should we prioritize our efforts on? (An option is of course "all, just take whatever the Tor Browser ships", but it's not obvious that it's the best solution for us, hence my question.)

A great part of the problem may be solved relatively easily by shipping a hybrid ISO again [1]. A first useful set of reports would be to try our obsolete Mac installation instructions [2] with a Tails ISO that was hybrided first, either with `isohybrid` (from the syslinux package, on GNU/Linux) or with `isohybrid.pl` (Perl version, can be taken from the syslinux source, should hopefully work on OSX), and reporting back if it works, how exactly it fails, and the exact hardware model / version. Also, trying with refind instead of refit would be nice too. Runa and other Mac users, could you please try this? The remaining part of the problem will be solved by adding UEFI support [3] to Tails. We're currently making plans with Debian Live upstream so that this support is added there, and benefits all Debian Live systems.

I'm more and more tempted to take the Git tag as the canonical form of distribution of the complete upstream release, which it seems to be in practice, given there's no tarball that I can find 10 days after the release was announced (and again, the Git tag suits me well).

I've compared the content of the tarball and the content of the tagged Git tree, and the result seems good enough. I'm not sure if it's on purpose that the tarball doesn't ship FAQ, README.TORDNS, nor doc/tsocks.conf.*, though. The previous release didn't either. > Please open tickets if so; caveat haxxor. :/ Sure. FWIW, it would be a bit easier to try and avoid reporting duplicates if there was a dedicated Trac tickets report, listed on the available reports page [1], for the torsocks component.

Personally, I have to say I absolutely do not regret this. > not only are you completely dependent on an upstream distro's > features implementation cycle I've no idea what misconceptions about Tails and Debian make you think this, but this is incorrect in practice. First, I fail to see what compiling binaries yourself buys you, in terms of your level of dependency on "upstream distro's features implementation cycle". But anyway, let's debunk this myth before it propagates any further. Most of the time, what prevents us from diverging from our various upstreams (Debian, Tor, Torbrowser to name a few) are design decisions and personal taste, and have nothing to do with basing our stuff on a binary distro: * It was decided early in Tails development to treat long-term maintenance as a very important criterion -- and generally, the smaller the delta we have to carry ourselves, the easier the maintenance. * We quite like to share tools, have them used by more people rather than just Tails users, maintain them with other people and not on our own. We quite dislike inventing wheels that only fit on the Tails car. All this is no news, should be quite easy to get when reading a bit about Tails development, and has been documented for a while on our "Relationship with upstreams" page: https://tails.boum.org/contribute/relationship_with_upstream/ So, yes, e.g. having UEFI support added to Debian Live makes sense to me, as opposed to implementing in a Tails-only way and maintaining it forever. Sure, it sometimes means we get the feature a bit later (which is not that clear in this specific case). > you are missing the opportunity to learn new things while > implementing those features yourself. If you intend to go on writing such bold public statements about Tails, then I'd rather give you first-hand information that you can base your affirmations on. Here we go, then. My experience absolutely does not match your assumption. I'm personally quite happy with how I've been learning new things when implementing features for Tails, be it when writing Tails-specific software, or when implementing the feature upstream, or when working to make Debian an awesome platform to build the next Tails generation upon. > I mean, Liberté was the first Linux distro to ship with a > UEFI Secure Boot-based trusted boot chain Congrats. > do you think you will ever be able to say something of the sort > about Tails?

I doubt we can blend in this "anonymity" set, though: unless Tails wants to forever copy the set of hosts ChromeOS queries (which I don't think we would want to rely upon on the long run), then Tails' use of tlsdate will probably be fingerprintable at least by the ISP if the connections are made in the clear, so we probably would want to run tlsdate over Tor anyway. So, I'm now considering this (tlsdate over Tor) to replace our use of htpdate, and not to replace our initial time guess based on the Tor consensus [1].

OK. Jacob, are you interested in implementing something like our current multiple pool -based approach [2], or something else with similar security properties?

Facts: * the homepage was changed in Tails 0.16, released on January 11 this year * the "Tails report for August, 2012" has boot statistics => We were publishing boot statistics _months before_ the browser home page was changed... no magic involved: the data from which these stats are computed simply does *not* depend on the web browser homepage.
