Tor
Tor的全称是“The Onion Router”是第二代洋葱路由(onion routing)的一种实现,用户通过Tor可以在因特网上进行匿名交流,是一个匿名代理服务器。最初该项目由美国海军研究实验室赞助。2004年後期,Tor成为电子前哨基金会的一个项目。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 0.2.5.7-rc 发布,此版本修复了在 0.2.5.x 系列的一些回退问题,还修复了一些关于 ORPort 可达性测试和发送 CREATE 单元失败的 bug。
压缩和签名文件已经提供下载:https://www.torproject.org/dist/,包和绑定稍后会提供下载。
改进列表
重要 bug 修复 (客户端,启动 ):
Start making circuits as soon as DisabledNetwork is turned off.
Resume expanding abbreviations for command-line options.
Warn about attempts to run hidden services and relays in the same
process: that's probably not a good idea.
重要 bug 修复(relay):
Avoid queuing or sending destroy cells for circuit ID zero when we
fail to send a CREATE cell.
Fix ORPort reachability detection on relays running behind a
proxy, by correctly updating the "local" mark on the controlling
channel when changing the address of an or_connection_t after the
handshake.
小特性 (bridge):
Add an ExtORPortCookieAuthFileGroupReadable option to make the
cookie file for the ExtORPort g+r by default.
小特性 (geoip):
Update geoip and geoip6 to the August 7 2014 Maxmind GeoLite2
Country database.
小的 bug 修复 (日志记录):
Reduce the log severity of the "Pluggable transport proxy does not
provide any needed transports and will not be launched." message,
since Tor Browser includes several ClientTransportPlugin lines in
its torrc-defaults file, leading every Tor Browser user who looks
at her logs to see these notices and wonder if they're dangerous.
Resolves bug 13124; bugfix on 0.2.5.3-alpha.
Downgrade "Unexpected onionskin length after decryption" warning
to a protocol-warn, since there's nothing relay operators can do
about a client that sends them a malformed create cell. Resolves
bug 12996; bugfix on 0.0.6rc1.
Log more specific warnings when we get an ESTABLISH_RENDEZVOUS
cell on a cannibalized or non-OR circuit. Resolves ticket 12997.
When logging information about an EXTEND2 or EXTENDED2 cell, log
their names correctly. Fixes part of bug 12700; bugfix
on 0.2.4.8-alpha.
When logging information about a relay cell whose command we don't
recognize, log its command as an integer. Fixes part of bug 12700;
bugfix on 0.2.1.10-alpha.
Escape all strings from the directory connection before logging
them. Fixes bug 13071; bugfix on 0.1.1.15. Patch from "teor".
Minor bugfixes (controller):
Restore the functionality of CookieAuthFileGroupReadable. Fixes
bug 12864; bugfix on 0.2.5.1-alpha.
Actually send TRANSPORT_LAUNCHED and HS_DESC events to
controllers. Fixes bug 13085; bugfix on 0.2.5.1-alpha. Patch
by "teor".
Minor bugfixes (compilation):
Fix compilation of test.h with MSVC. Patch from Gisle Vanem;
bugfix on 0.2.5.5-alpha.
Make the nmake make files work again. Fixes bug 13081. Bugfix on
0.2.5.1-alpha. Patch from "NewEraCracker".
In routerlist_assert_ok(), don't take the address of a
routerinfo's cache_info member unless that routerinfo is non-NULL.
Fixes bug 13096; bugfix on 0.1.1.9-alpha. Patch by "teor".
Fix a large number of false positive warnings from the clang
analyzer static analysis tool. This should make real warnings
easier for clang analyzer to find. Patch from "teor". Closes
ticket 13036.
Distribution (systemd):
Verify configuration file via ExecStartPre in the systemd unit
file. Patch from intrigeri; resolves ticket 12730.
Explicitly disable RunAsDaemon in the systemd unit file. Our
current systemd unit uses "Type = simple", so systemd does not
expect tor to fork. If the user has "RunAsDaemon 1" in their
torrc, then things won't work as expected. This is e.g. the case
on Debian (and derivatives), since there we pass "--defaults-torrc
/usr/share/tor/tor-service-defaults-torrc" (that contains
"RunAsDaemon 1") by default. Patch by intrigeri; resolves
ticket 12731.
Documentation:
Adjust the URLs in the README to refer to the new locations of
several documents on the website. Fixes bug 12830. Patch from
Matt Pagan.
Document 'reject6' and 'accept6' ExitPolicy entries. Resolves
ticket 12878.
Tor 是一个帮助你抵御流量分析的软件项目, 流量分析是一种对网络的监视行为。Tor 将你的通信通过一个由遍及全球的志愿者运行的中继(relay)所组成的分布式网络转发, 以此来保护你的安全:它令监视你的 Internet 连接的那些人无法知道你所访问的站点, 它还令你所访问的站点无法知道你的物理位置。Tor 能与现有的许多应用程序配合工作, 包括 Web 浏览器、即时通讯客户端、远程登录和基于 TCP 协议的其他应用程序。
