自建独享落地节点

适用于对 IP 质量要求较高的用户，需要一定的理解与动手能力

基于 L4 转发，理论上支持任何协议，以下仅为示例

系统建议：Linux Debian 10 及以上
运行环境：Docker
运行软件：Shadowsocks rust

安装步骤

apt install docker.io -y

docker pull ghcr.io/shadowsocks/ssserver-rust && \
docker run --entrypoint ssserver \
        -d --name=shadowsocks \
           --net=host \
           --restart=always \
           --log-driver json-file \
           --log-opt max-size=10m \
           --log-opt max-file=3 \
        ghcr.io/shadowsocks/ssserver-rust \
        -s "[::]:8080" -m "aes-128-gcm" -k "Password" -U

or (DNS)

docker pull ghcr.io/shadowsocks/ssserver-rust && \
docker run --entrypoint ssserver \
        -d --name=shadowsocks \
           --net=host \
           --restart=always \
           --log-driver json-file \
           --log-opt max-size=10m \
           --log-opt max-file=3 \
        ghcr.io/shadowsocks/ssserver-rust \
        -s "[::]:8080" -m "aes-128-gcm" -k "Password" -U --dns "1.1.1.1,1.0.0.1"

or (IPv6 first)

docker pull ghcr.io/shadowsocks/ssserver-rust && \
docker run --entrypoint ssserver \
        -d --name=shadowsocks \
           --net=host \
           --restart=always \
           --log-driver json-file \
           --log-opt max-size=10m \
           --log-opt max-file=3 \
        ghcr.io/shadowsocks/ssserver-rust \
        -s "[::]:8080" -m "aes-128-gcm" -k "Password" -U -6

对 Telegram Bot 发送指令 "/ssserver" 或 "/ssserver_v6" 即可获取与本站个人端口加密/协议一致的部署命令

添加流量转发规则

选择起源节点
填入目标服务器地址
填入目标端口
勾选[目标节点与本站个人端口加密/协议一致]（如果没有采用 Telegram Bot 命令部署请跳过此步骤）

一分钟内自动生效，正常情况下在代理客户端选择起源节点即可

口碑较好的商家（排名不分先后）

配合流量转发，仅需购买国际宽带网络（Routing Profile: Standard）VPS/VDS
