# TProxy
容器化的旁路由透明代理工具,使用Xray处理TProxy流量,实现拥有独立IP与MAC地址的虚拟化代理网关,支持 `amd64`、`i386`、`arm64`、`armv7` 四种CPU架构,可代理任意TCP与UDP流量。
4 years ago
TProxy使用Docker容器化部署,在[Docker Hub](https://hub.docker.com/repository/docker/dnomd343/tproxy)可获取已构建的镜像。

## 部署
首先开启网卡混杂模式
```
shell> ip link set eth0 promisc on
```
创建 `macvlan` 网络
```
# 此处网段与网关信息需按实际网络指定
shell> docker network create -d macvlan \
--subnet=192.168.2.0/24 \
--gateway=192.168.2.1 \
-o parent=eth0 macvlan
```

选择一个目录存储数据,此处使用 `/etc/scutweb`
4 years ago
```
shell> mkdir /etc/scutweb
shell> cd /etc/scutweb
shell> vim custom.sh
```
4 years ago
`custom.sh` 将在容器启动时首先执行,可用于指定容器IP与网关地址
4 years ago
```
# 此处指定网关为192.168.2.1,容器IP为192.168.2.2
ip addr flush dev eth0
ip addr add 192.168.2.2/24 brd 192.168.2.255 dev eth0
ip route add default via 192.168.2.1
```

启动容器,此处映射时间与时区信息到容器中,可以与宿主机进行同步(容器内默认为UTC零时区),用于日志时间记录
4 years ago
```
# 容器名称和存储目录可自行指定
docker run --restart always \
--name scutweb \
--network macvlan \
--privileged -d \
--volume /etc/scutweb/:/etc/xray/expose/ \
--volume /etc/timezone:/etc/timezone:ro \
--volume /etc/localtime:/etc/localtime:ro \
dnomd343/tproxy
```
使用以下命令查看容器运行状态
```
shell> docker ps -a
```
容器成功运行以后,将会在存储目录下生成多个文件和文件夹
+ `log`:文件夹,存储Xray日志文件
+ `segment`:文件夹,存储不代理的网段信息
+ `outbounds.json`:指定流量出口信息
+ `routeing.json`:指定流量路由信息
`outbounds.json` 默认配置流量转发给网关,需要用户手动配置为上游接口,具体语法见[Xray文档](https://xtls.github.io/config/base/outbounds/)
```
{
"outbounds": [
{
"tag": "node",
"protocol": "freedom"
}
]
}
```
`routing.json` 默认配置将全部流量交由 `node` 接口,即 `outbounds.json` 中的 `freedom` 出口,具体语法见[Xray文档](https://xtls.github.io/config/base/routing/)

},

{
"type": "field",
"network": "tcp,udp"
4 years ago
"outboundTag": "node"
}
]
}
}
```
`dns.json` 指定路由匹配时的DNS服务器,具体语法见[Xray文档](https://xtls.github.io/config/base/dns/)
```
{
"dns": {
"servers": [
"223.5.5.5",
"119.29.29.29"
]
}
}
```
`segment` 文件夹下默认存储 `ipv4``ipv6` 两个文件,其中存储不代理的网段信息,建议绕过内网地址、本地回环地址、链路本地地址、组播地址等网段
4 years ago
```
# IPv4与IPv6均默认绕过组播地址
shell> cat /etc/scutweb/segment/ipv4
127.0.0.0/8
169.254.0.0/16
224.0.0.0/3
shell> cat /etc/scutweb/segment/ipv6

FC00::/7

FF00::/8
```

配置完成后重启容器生效
4 years ago
```
shell> docker restart scutweb
```
此时宿主机无法与macvlan网络直接连接,需要手动配置桥接,这里以Debian系Linux发行版为例
```
shell> vim /etc/network/interfaces
```
补充如下配置
```
# 具体网络信息需要按实际情况指定
auto eth0
iface eth0 inet manual
auto macvlan
iface macvlan inet static
address 192.168.2.34
netmask 255.255.255.0
gateway 192.168.2.2
dns-nameservers 192.168.2.3
pre-up ip link add macvlan link eth0 type macvlan mode bridge
post-down ip link del macvlan link eth0 type macvlan mode bridge
```
重启宿主机生效
```
shell> reboot

预设接口
+ `Socks5代理`: 1080端口,支持UDP,无授权,标志为 `socks`
+ `HTTP代理`: 1081端口,无授权,标志为 `http`
+ `全局Socks5代理`: 10808端口,支持UDP,无授权,标志为 `proxy`
