zh-cn/volunteer.wml  146) <br />
zh-cn/volunteer.wml  147) The Tor Browser bundle incorporates Tor, Firefox, and the Vidalia user
zh-cn/volunteer.wml  148) interface (and optionally Pidgin IM). Components are pre-configured to
zh-cn/volunteer.wml  149) operate in a secure way, and it has very few dependencies on the
zh-cn/volunteer.wml  150) installed operating system. It has therefore become one of the most
zh-cn/volunteer.wml  151) easy to use, and popular, ways to use Tor on Windows.
zh-cn/volunteer.wml  152) <br />
zh-cn/volunteer.wml  153) However, there is currently no comparable package for Linux and Mac OS
zh-cn/volunteer.wml  154) X, so this project would be to implement Tor Browser Bundle for these
zh-cn/volunteer.wml  155) platforms. This will involve modifications to Vidalia (C++), possibly
zh-cn/volunteer.wml  156) Firefox (C) then creating and testing the launcher on a range of
zh-cn/volunteer.wml  157) operating system versions and configurations to verify portability.
zh-cn/volunteer.wml  158) <br />
zh-cn/volunteer.wml  159) Students should be familiar with application development on one or
zh-cn/volunteer.wml  160) preferably both of Linux and Mac OS X, and be comfortable with C/C++
zh-cn/volunteer.wml  161) and shell scripting.
zh-cn/volunteer.wml  162) <br />
zh-cn/volunteer.wml  163) Part of this project could be usability testing of Tor Browser Bundle,
zh-cn/volunteer.wml  164) ideally amongst our target demographic.
zh-cn/volunteer.wml  165) That would help a lot in knowing what needs to be done in terms of bug

zh-cn/volunteer.wml  184) in place for Vidalia, Torbutton, and Torcheck. However, Pootle only
zh-cn/volunteer.wml  185) translates strings that are in the "po" format, and our website uses wml

zh-cn/volunteer.wml  226) >是提高了抵抗政府机关或者组织探测的能力。但是 Tor 的反审查设计在某些方面仍然需要
zh-cn/volunteer.wml  227) 更好的机制来改进。比如,现在 Tor 只能在一个 地址/端口  对上进行监听,
zh-cn/volunteer.wml  228) 有<a href="<svnsandbox>doc/spec/proposals/118-multiple-orports.txt">建议放开这个限制</a>,
zh-cn/volunteer.wml  229) 并允许客户端可以连接到任意给定的 Tor 地址和端口上,但是,这需要大量的工作。另外一个
zh-cn/volunteer.wml  230) 提高反审查能力的方案(更加复杂和困难)希望能够提高 Tor 对端口扫描的抵抗能力。现在,恶意
zh-cn/volunteer.wml  231) 的扫描者可以通过尝试连接一个假定的 Tor 主机,向其发送 Tor 协议包,并检查它的响应来确定
zh-cn/volunteer.wml  232) 它是否在运行<a href="<svnsandbox>doc/spec/proposals/125-bridges.txt"> Tor 网桥</a>。
zh-cn/volunteer.wml  233) 要解决这个问题,当受到端口扫描工具扫描的时候,网桥应该

zh-cn/volunteer.wml  235) (HTTP或者HTTPS),如果对方没有提供正确的网桥 key,那么它不会作出正确的网桥连接响应。
zh-cn/volunteer.wml  236) <br />
zh-cn/volunteer.wml  237) 这部分的工作需要大量的研究和设计。一个巨大的挑战是,即使一个攻击者知道我们的算法和机制,

zh-cn/volunteer.wml  252) 现在,Tor 中继自己估算并报告自己的带宽能力,Tor 客户端则根据中继的带宽报告

zh-cn/volunteer.wml  254) 中继谎报带宽的攻击</a>变得非常容易。为了改善这个问题,Tor 计算最大带宽的交,

zh-cn/volunteer.wml  303) is a relatively new software to allow assisted updates of Tor and related
zh-cn/volunteer.wml  304) software. Currently, there are very few users, but we expect Thandy to be

zh-cn/volunteer.wml  323) <br />
zh-cn/volunteer.wml  324) There are a number of status changes inside Tor of which the user may need
zh-cn/volunteer.wml  325) to be informed. For example, if the user is trying to set up his Tor as a
zh-cn/volunteer.wml  326) relay and Tor decides that its ports are not reachable from outside
zh-cn/volunteer.wml  327) the user's network, we should alert the user. Currently, all the user
zh-cn/volunteer.wml  328) gets is a couple log messages in Vidalia's 'message log' window, which they
zh-cn/volunteer.wml  329) likely never see since they don't receive a notification that something
zh-cn/volunteer.wml  330) has gone wrong. Even if the user does actually look at the message log,
zh-cn/volunteer.wml  331) most of the messages make little sense to the novice user.
zh-cn/volunteer.wml  332) <br />
zh-cn/volunteer.wml  333) Tor has the ability to inform Vidalia of many such status changes, and
zh-cn/volunteer.wml  334) we recently implemented support for a couple of these events. Still,
zh-cn/volunteer.wml  335) there are many more status events the user should be informed of and we
zh-cn/volunteer.wml  336) need a better UI for actually displaying them to the user.
zh-cn/volunteer.wml  337) <br />
zh-cn/volunteer.wml  338) The goal of this project then is to design and implement a UI for
zh-cn/volunteer.wml  339) displaying Tor status events to the user. For example, we might put a
zh-cn/volunteer.wml  340) little badge on Vidalia's tray icon that alerts the user to new status
zh-cn/volunteer.wml  341) events they should look at. Double-clicking the icon could bring up a
zh-cn/volunteer.wml  342) dialog that summarizes recent status events in simple terms and maybe
zh-cn/volunteer.wml  343) suggests a remedy for any negative events if they can be corrected by
zh-cn/volunteer.wml  344) the user. Of course, this is just an example and one is free to
zh-cn/volunteer.wml  345) suggest another approach.
zh-cn/volunteer.wml  346) <br />
zh-cn/volunteer.wml  347) A person undertaking this project should have good UI design and layout
zh-cn/volunteer.wml  348) and some C++ development experience. Previous experience with Qt and
zh-cn/volunteer.wml  349) Qt's Designer will be very helpful, but are not required. Some
zh-cn/volunteer.wml  350) English writing ability will also be useful, since this project will
zh-cn/volunteer.wml  351) likely involve writing small amounts of help documentation that should
zh-cn/volunteer.wml  352) be understandable by non-technical users. Bonus points for some graphic
zh-cn/volunteer.wml  353) design/Photoshop fu, since we might want/need some shiny new icons too.

zh-cn/volunteer.wml  367) Tor needs to be far more tested. This is a multi-part effort. To start
zh-cn/volunteer.wml  368) with, our unit test coverage should rise substantially, especially in
zh-cn/volunteer.wml  369) the areas outside the utility functions. This will require significant
zh-cn/volunteer.wml  370) refactoring of some parts of Tor, in order to dissociate as much logic
zh-cn/volunteer.wml  371) as possible from globals.
zh-cn/volunteer.wml  372) <br />
zh-cn/volunteer.wml  373) Additionally, we need to automate our performance testing. We've got
zh-cn/volunteer.wml  374) buildbot to automate our regular integration and compile testing already
zh-cn/volunteer.wml  375) (though we need somebody to set it up on Windows),
zh-cn/volunteer.wml  376) but we need to get our network simulation tests (as built in <a
zh-cn/volunteer.wml  377) href="https://svn.torproject.org/svn/torflow/trunk/README">TorFlow</a>)
zh-cn/volunteer.wml  378) updated for more recent versions of Tor, and designed to launch a test
zh-cn/volunteer.wml  379) network either on a single machine, or across several, so we can test

zh-cn/volunteer.wml  394) Reanimate one of the approaches to implement a Tor client in Java,

zh-cn/volunteer.wml  397) href="http://code.google.com/android/">Android</a>. The first step
zh-cn/volunteer.wml  398) would be to port the existing code and execute it in an Android
zh-cn/volunteer.wml  399) environment. Next, the code should be updated to support the newer Tor
zh-cn/volunteer.wml  400) protocol versions like the <a href="<svnsandbox>doc/spec/dir-spec.txt">v3
zh-cn/volunteer.wml  401) directory protocol</a>. Further, support for requesting or even

zh-cn/volunteer.wml  404) A prospective developer should be able to understand and write new Java

zh-cn/volunteer.wml  485) Many users of Tor have poor-quality Internet connections, giving low
zh-cn/volunteer.wml  486) bandwidth, high latency, and high packet loss/re-ordering. User
zh-cn/volunteer.wml  487) experience is that Tor reacts badly to these conditions, but it is

zh-cn/volunteer.wml  489) problems in the lab.
zh-cn/volunteer.wml  490) <br />
zh-cn/volunteer.wml  491) This project would be to build a simulation environment which

zh-cn/volunteer.wml  516) 传输路径。现在的地图缺少交互功能而且图像质量也很差。事实上,我们已经实现了一个基于 KDE 的
zh-cn/volunteer.wml  517) Marble widget,这让我们可以提供更好的图像质量并且可以改善交互功能,比如允许用户点击单个中继或者

zh-cn/volunteer.wml  519) 告诉 Tor:我想从这里退出。
zh-cn/volunteer.wml  520) <br />

zh-cn/volunteer.wml  605) that allows signing up to receive notifications via email when the

zh-cn/volunteer.wml  608) have to shut down their relay regularly. During the project, Tor
zh-cn/volunteer.wml  609) weather could be extended to allow more flexible configurations.
zh-cn/volunteer.wml  610) Other enhancements are also possible: Weather could send out warnings
zh-cn/volunteer.wml  611) when your relay runs an out-of-date version of Tor, or when its
zh-cn/volunteer.wml  612) observed bandwith drops below a certain value. It might also be a

zh-cn/volunteer.wml  638) 一个节点如果回路断裂的情况出现得太多,那么它不应该被标记为可用的状态。也许,
zh-cn/volunteer.wml  639) 应该忽略它自己宣称的带宽而代之以某个处罚比例的计算结果来标记,或者,就直接标记

zh-cn/volunteer.wml  659) <br />
zh-cn/volunteer.wml  660) 目前在Debian/Ubuntu上,Vidalia 的缺省安装包运行的不算太好。当前的安装包用 debian-tor
zh-cn/volunteer.wml  661) 用户缺省的以守护进程运行 Tor,但是没有在缺省的 torrc 文件中定义
zh-cn/volunteer.wml  662) <a href="<svnsandbox>doc/spec/control-spec.txt">控制端口</a>。
zh-cn/volunteer.wml  663) 因此,Vidalia 会发现无法找到已经运行的 Tor 程序于是试图自行启动一个新的 Tor 进程,
zh-cn/volunteer.wml  664) 然后,这个进程会失败并退出,Vidalia 会得到一个错误消息并报告给用户,用户会因此而
zh-cn/volunteer.wml  665) 感到困惑,他们实际上已经有一个可用的 Tor 进程了,但仍然被报告错误。
zh-cn/volunteer.wml  666) <br />
zh-cn/volunteer.wml  667) 现在的解决方案是,告诉用户停止掉缺省的 Tor 守护进程,让 Vidalia 来启动 Tor,或者向
zh-cn/volunteer.wml  668) 用户解释如何在他们的 torrc 文件中设定控制端口和密码。Debian 上的一个更好的解决办法
zh-cn/volunteer.wml  669) 应该是使用 Tor 的ControlSocket,这样Vidalia可以通过Unix domain socket与 Tor 通讯,最好
zh-cn/volunteer.wml  670) 能够在 Tor 的 Debian 发布包中将其设定为缺省的方式,这样,如果用户同样用 debian-tor
zh-cn/volunteer.wml  671) 组来运行 Vidalia的话,Vidalia就可以用基于文件的认证方式(cookie)来连接 Tor。
zh-cn/volunteer.wml  672) <br />
zh-cn/volunteer.wml  673) 首先要做的是为 Vidalia 增加对 Tor 的 ControlSocket 的支持,开发并测试符合Debian和Ubuntu
zh-cn/volunteer.wml  674) 标准的发布包,并确认它能够和已有的 Tor 发布包一起正常工作。我们可以为此提供一个资料库
zh-cn/volunteer.wml  675) 以及相应的host服务。
zh-cn/volunteer.wml  676) <br />
zh-cn/volunteer.wml  677) 接下来的挑战是,既然在固定的位置(<code>/etc/tor/torrc</code>)可以找到 Tor 的控制文件,
zh-cn/volunteer.wml  678) 那么我们应该可以找到一个办法允许 Vadilia 修改 Tor 的控制文件(torrc)。我们能想到的最好的
zh-cn/volunteer.wml  679) 办法是当 Vadilia 启动后它可以通过控制端口(ControlSocket)向 Tor 提供一个新的配置,但是,
zh-cn/volunteer.wml  680) 有个问题是这可能会覆盖用户自己希望的配置。另外一个不错的想法是,由 Vadilia 创建一个临时
zh-cn/volunteer.wml  681) 配置文件并提示用户手工将其覆盖<code>/etc/tor/torrc</code>,这同样有个问题,用户会被
zh-cn/volunteer.wml  682) 要求直接操作文件,但通常我们不应该这样。

zh-cn/volunteer.wml  695) <br />
zh-cn/volunteer.wml  696) 我们需要一个良好的可认证的更新框架。现在 Vidalia 通过检查 Tor 的目录信息,可以发现用户在
zh-cn/volunteer.wml  697) 运行一个较旧的或者不再被推荐的 Tor 版本,并通知用户。但它只是简单的弹出一个小小的消息框
zh-cn/volunteer.wml  698) 告诉用户他需要手动升级自己的 Tor 版本。我们的目标是能够扩展 Vidalia 的功能使之能够自动下载
zh-cn/volunteer.wml  699) 最新的 Tor 并自动安装。我们希望在可能的时候通过 Tor 来完成这个事情,但是也可以考虑其他
zh-cn/volunteer.wml  700) 更好的办法。如果时间许可,我们也希望可以一起更新 Tor 套件中的其他软件,比如 Polipo 和 Vidalia
zh-cn/volunteer.wml  701) 自己。
zh-cn/volunteer.wml  702) <br />
zh-cn/volunteer.wml  703) 要完成这项工作,研究者必须首先评估已有的自动更新框架,比如 OS X上的 Sparkle,并评估它们的
zh-cn/volunteer.wml  704) 功能,弱点,安全问题,以及与 Vidalia 的整合性。如果找不到合适的现成的解决方案,那么研究者就
zh-cn/volunteer.wml  705) 需要自行设计一个自动更新框架,并写出设计文档供其他开发者讨论和评估它的安全风险。研究者
zh-cn/volunteer.wml  706) 需要实现他自己的框架(或者整合一个既有的)并进行测试。
zh-cn/volunteer.wml  707) <br />
zh-cn/volunteer.wml  708) 从事这项工作需要良好的 C++ 开发经验,Qt 的开发经验会有所帮助但不是必需的,同时,还需要充分

zh-cn/volunteer.wml  871) selecting appropriate Tor circuits based upon exit node requirements
zh-cn/volunteer.wml  872) specified by the user) to gather data in a self-contained way, with
zh-cn/volunteer.wml  873) parameters easily configurable by the user.  Blossom is presently
zh-cn/volunteer.wml  874) implemented as a single Python script that interfaces with Tor using the
zh-cn/volunteer.wml  875) Controller interface and depends upon metadata about Tor nodes obtained
zh-cn/volunteer.wml  876) via external processes, such as a webpage indicating status of the nodes
zh-cn/volunteer.wml  877) plus publically available data from DNS, whois, etc.  This project has
zh-cn/volunteer.wml  878) two parts: (1) Determine which additional metadata may be useful and
zh-cn/volunteer.wml  879) rework Blossom so that it cleanly obtains the metadata on its own rather
zh-cn/volunteer.wml  880) than depend upon external scripts (this may, for example, involve
zh-cn/volunteer.wml  881) additional threads or inter-process communication), and (2) develop a
zh-cn/volunteer.wml  882) means by which the user can easily configure Blossom, starting with a
zh-cn/volunteer.wml  883) configuration file and possibly working up to a web configuration engine.
zh-cn/volunteer.wml  884) Knowledge of Tor and Python are important; knowledge of
zh-cn/volunteer.wml  885) TCP, interprocess communication, and Perl will also be helpful.  An

zh-cn/volunteer.wml  893) <br />
zh-cn/volunteer.wml  894) Develop and implement a means of affording Blossom
zh-cn/volunteer.wml  895) users the ability to qualitatively describe the exit node that they
zh-cn/volunteer.wml  896) want.  The Internet is an inconsistent place: some Tor exit nodes see
zh-cn/volunteer.wml  897) the world differently than others.  As presently implemented, Blossom (a
zh-cn/volunteer.wml  898) tool for monitoring and selecting appropriate Tor circuits based upon
zh-cn/volunteer.wml  899) exit node requirements specified by the user) lacks a sufficiently rich
zh-cn/volunteer.wml  900) language to describe how the different vantage points are different.
zh-cn/volunteer.wml  901) For example, some exit nodes may have an upstream network that filters
zh-cn/volunteer.wml  902) certain kinds of traffic or certain websites.  Other exit nodes may
zh-cn/volunteer.wml  903) provide access to special content as a result of their location, perhaps
zh-cn/volunteer.wml  904) as a result of discrimination on the part of the content providers
zh-cn/volunteer.wml  905) themselves.  This project has two parts: (1) develop a language for
zh-cn/volunteer.wml  906) describing characteristics of networks in which exit nodes reside, and
zh-cn/volunteer.wml  907) (2) incorporate this language into Blossom so that users can select Tor
zh-cn/volunteer.wml  908) paths based upon the description.
zh-cn/volunteer.wml  909) Knowledge of Tor and Python are important; knowledge of
zh-cn/volunteer.wml  910) TCP, interprocess communication, and Perl will also be helpful.  An
zh-cn/volunteer.wml  911) interest in network neutrality is important as well, since the

zh-cn/volunteer.wml 1108) network with too many circuit extend operations, yet to also avoid having
zh-cn/volunteer.wml 1109) clients use the same circuit for so long that the exit node can build a
zh-cn/volunteer.wml 1110) useful pseudonymous profile of them. Alas, ten minutes is probably way
zh-cn/volunteer.wml 1111) too long, especially if connections from multiple protocols (e.g. IM and
zh-cn/volunteer.wml 1112) web browsing) are put on the same circuit. If we keep fixed the overall
zh-cn/volunteer.wml 1113) number of circuit extends that the network needs to do, are there more
zh-cn/volunteer.wml 1114) efficient and/or safer ways for clients to allocate streams to circuits,
zh-cn/volunteer.wml 1115) or for clients to build preemptive circuits? Perhaps this research item
zh-cn/volunteer.wml 1116) needs to start with gathering some traces of what connections typical
zh-cn/volunteer.wml 1117) clients try to launch, so you have something realistic to try to optimize.

zh-cn/volunteer.wml 1121) <li>How many bridge relays do you need to know to maintain
zh-cn/volunteer.wml 1122) reachability? We should measure the churn in our bridges. If there is
zh-cn/volunteer.wml 1123) lots of churn, are there ways to keep bridge users more likely to stay
zh-cn/volunteer.wml 1124) connected?
