Tor v0.2.1.8 Alpha 多国语言版 - 匿名代理
http://img.cnbeta.com/topics/tor.gif Tor(The Onion Router)是第二代onion routing(洋葱路由)的一种实现,用户通过Tor可以在因特网上进行匿名交流.最初该项目由美国海军研究实验室(US Naval ResearchLaboratory)赞助.2004年晚些时候,Tor成为电子前哨基金会(Electronic FrontierFoundation,EFF)的一个项目.2005年后期,EFF不再赞助Tor项目,但他们继续维持Tor的官方网站.
Tor是一个工具集，帮助各类组织和个人增强互联网上活动的安全。 Tor 能够匿名 Web 浏览与发布、即时通讯、IRC、SSH 和其他基于 TCP协议的应用。 Tor 同时提供了一个平台，软件开发人员能够在上面构建具有内建匿名性、安全性与隐私保护特性的新的应用程序。
Tor的目标是抵御流量分析，流量分析是一种对网络的监视行为，这种行为会威胁个人的匿名与隐私，商业活动与业务关系的保密和国家的安全。通信在一个由叫做“洋葱路由器”的服务器所构建的分布式网络上传输，保护你以免网站构建你的兴趣简档，本地的、甚至是洋葱路由器上的窃听者阅读你的数据、了解你所访问的站点。
Tor 的安全性随着用户群的扩大和更多的人志愿运行服务器而得到增强。请考虑贡献你的时间或者贡献你的带宽。最后请记住，这是一项进行中的项目——如果你真的需要强健的匿名，现有的 Tor 网络也许并不适合。
Tor v0.2.0.32
2008-11-21
Security fixes:
- The "User" and "Group" config options didnot clear the supplementary group entries for the Tor process. The"User" option is now more robust, and we now set the groups to thespecified user's primary group. The "Group" option is now ignored. Formore detailed logging on credential switching, set CREDENTIAL_LOG_LEVELin common/compat.c to LOG_NOTICE or higher. Patch by Jacob Appelbaumand Steven Murdoch. Bugfix on 0.0.2pre14. Fixes bug 848 and 857.
- The "ClientDNSRejectInternalAddresses" config option wasn't beingconsistently obeyed: if an exit relay refuses a stream because its exitpolicy doesn't allow it, we would remember what IP address the relaysaid the destination address resolves to, even if it's an internal IPaddress. Bugfix on 0.2.0.7-alpha; patch by rovv.
Major bugfixes:
- Fix a DOS opportunity during the voting signature collection processat directory authorities. Spotted by rovv. Bugfix on 0.2.0.x.
Major bugfixes (hidden services):
- When fetching v0 and v2 rendezvous service descriptors in parallel,we were failing the whole hidden service request when the v0 descriptorfetch fails, even if the v2 fetch is still pending and might succeed.Similarly, if the last v2 fetch fails, we were failing the whole hiddenservice request even if a v0 fetch is still pending. Fixes bug 814.Bugfix on 0.2.0.10-alpha.
- When extending a circuit to a hidden service directory to upload arendezvous descriptor using a BEGIN_DIR cell, almost 1/6 of allrequests failed, because the router descriptor has not been downloadedyet. In these cases, do not attempt to upload the rendezvousdescriptor, but wait until the router descriptor is downloaded andretry. Likewise, do not attempt to fetch a rendezvous descriptor from ahidden service directory for which the router descriptor has not yetbeen downloaded. Fixes bug 767. Bugfix on 0.2.0.10-alpha.
Minor bugfixes:
- Fix several infrequent memory leaks spotted by Coverity.
- When testing for libevent functions, set the LDFLAGS variable correctly. Found by Riastradh.
- Avoid a bug where the FastFirstHopPK 0 option would keep Tor frombootstrapping with tunneled directory connections. Bugfix on0.1.2.5-alpha. Fixes bug 797. Found by Erwin Lam.
- When asked to connect to A.B.exit:80, if we don't know the IP for Aand we know that server B rejects most-but-not all connections to port80, we would previously reject the connection. Now, we assume the userknows what they were asking for. Fixes bug 752. Bugfix on 0.0.9rc5.Diagnosed by BarkerJr.
- If we overrun our per-second write limits a little, count this ashaving used up our write allocation for the second, and choke outgoingdirectory writes. Previously, we had only counted this when we had metour limits precisely. Fixes bug 824. Patch from by rovv. Bugfix on0.2.0.x (??).
- Remove the old v2 directory authority 'lefkada' from the default list. It has been gone for many months.
- Stop doing unaligned memory access that generated bus errors on sparc64. Bugfix on 0.2.0.10-alpha. Fixes bug 862.
- Make USR2 log-level switch take effect immediately. Bugfix on 0.1.2.8-beta.
Minor bugfixes (controller):
- Make DNS resolved events into "CLOSED", not "FAILED". Bugfix on 0.1.2.5-alpha. Fix by Robert Hogan. Resolves bug 807.
