1. 下载并安装 Tor
|
|
2. 安装 obfs4
通过python进行编译安装:
(1)安装 所需依赖软件模块:
|
|
(2)安装 obfs4proxy:
|
|
通过go进行编译安装:
(1)下载go的obfs4项目:
|
|
(2)进入obfs4目录进行编译:
|
|
(3)复制bofs4proxy到系统工作目录下:
|
|
3. 配置 Tor Bridges
编辑/etc/tor/torrc
:
|
|
定义一个 ORPort,不作为出口节点,设置成 Bridge:
Log notice file /var/log/tor/notices.log
RunAsDaemon 1
ORPort 6666
Exitpolicy reject :
BridgeRelay 1
ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy
ExtORPort auto
PublishServerDescriptor 0
重启tor服务:
|
|
查看tor服务状态
|
|
4. 使用网桥
查看日志文件,命令:
|
|
内容如下:
[notice] Your Tor server’s identity key fingerprint is ‘Unnamed
530FA95A79B9145D315F15F01215BE2F3BE921EB’ [notice] Your Tor bridge’s
hashed identity key fingerprint is ‘Unnamed
83D1AC9EC2F15D7024278461DC91A8B2E9BBF43A’ [notice] Registered server
transport ‘obfs4’ at ‘[::]:46396’ [notice] Tor has successfully opened
a circuit. Looks like client functionality is working. [notice]
Bootstrapped 100%: Done [notice] Now checking whether ORPort
:6666 is reachable… (this may take up to 20 minutes – look for log messages indicating success) [notice] Self-testing
indicates your ORPort is reachable from the outside. Excellent.
注意:记住输出中 obfs4 监听的端口(本例中是 46396)。并且还能找到你的 server identity fingerprint(本例中是 530FA95A79B9145D315F15F01215BE2F3BE921EB),也复制下来。
在 /var/lib/tor/pt_state/obfs4_bridgeline.txt 文件中可以看到类似如下的内容:
Bridge obfs4
: cert=oG6a3K7CtearIloUp2OCUk60oNMgw+jVgCNhGumMkODS659UEgRRx7yxZuoEo9Crp9GGXg
iat-mode=0
根据日志中的信息获得最终的网桥配置: obfs4
:46396 530FA95A79B9145D315F15F01215BE2F3BE921EB
cert=6LMNcXh6MIfApbZiMksnS4Kj+2sffZ5pybSqtcOO5YoHgfrMpkBJqvLxhuR2Ppau0L2seg
iatmode=0
- 防火墙firewalld放行端口
编辑防火墙公共配置/etc/firewalld/zones/public.xml文件,命令:
|
|
内容如下(本例ORPort端口 => 6666, obfs4端口 => 46396):
|
|
使防火墙配置生效,命令:
