利用shadowducks翻墙(速度不错）

登陆linux vps.

首先搭建java环境:
apt-get install -y default-jdk或者openjdk-8-jdk 
（centos系统下，则yum install -y java-1.8.0-openjdk)

这样jdk环境就搭建好了。

接着是搭建maven环境:

建议这样安装Maven：

apt-get install -y maven*

(yum install -y maven*)

运行 mvn -version 命令，检验是否正确地安装了 Maven.

然后，

git clone https://github.com/netfreer/shadowducks  shadowducks-by-netfreer。

cd shadowducks-by-netfreer

mvn package

此命令会在./shadowducks-server/下面生成target目录。

cd shadowducks-server/target

java -jar shadowducks-server-1.0-SNAPSHOT-jar-with-dependencies.jar

会显示：

...

20-04-23 17:16:16 [main] INFO  c.g.n.s.s.DucksServer - Start listen tcp port 0.0.0.0 on address 2999, method: aes-256-cfb, password: password.

20-04-23 17:16:16 [main] INFO  c.g.n.s.s.DucksServer - Start listen udp port 0.0.0.0 on address 2999, method: aes-256-cfb, password: password.

20-04-23 17:16:16 [main] INFO  c.g.n.s.s.DucksServer - start server success !

先按ctrl+c,终止运行此命令。

cd /root/shadowducks-by-netfreer/

grep -r -n 2999 .

显示：

./shadowducks-common/src/main/java/com/github/netfreer/shadowducks/common/config/ConfigUtil.java:17:        int port = 2999;

于是，

nano ./shadowducks-common/src/main/java/com/github/netfreer/shadowducks/common/config/ConfigUtil.java

(在ConfigUtil.java文件的第17行，改2999为3999.在第24行，把password的值改为你的密码，比如yourpassword)

rm -rf ./shadowducks-server/target/

mvn package

ls shadowducks-server

显示：
pom.xml  src  target
（可以见到重新生成了target目录。）

cd shadowducks-server/target

java -jar shadowducks-server-1.0-SNAPSHOT-jar-with-dependencies.jar

会显示：

...

20-04-23 17:38:07 [main] INFO  c.g.n.s.s.DucksServer - Start listen tcp port 0.0.0.0 on address 3999, method: aes-256-cfb, password: yourpassword.

20-04-23 17:38:07 [main] INFO  c.g.n.s.s.DucksServer - Start listen udp port 0.0.0.0 on address 3999, method: aes-256-cfb, password: yourpassword.

20-04-23 17:38:07 [main] INFO  c.g.n.s.s.DucksServer - start server success !

不过命令：java -jar shadowducks-server-1.0-SNAPSHOT-jar-with-dependencies.jar是运行在前台的，我们可以使用systemd把它运行为service:

nano /etc/systemd/system/shadowducks.service

cat /etc/systemd/system/shadowducks.service

[Unit]

After=network.target

[Service]

WorkingDirectory=/root/shadowducks-by-netfreer/shadowducks-common/src/main/java/com/github/netfreer/shadowducks/common/config/

ExecStart=/usr/bin/java -jar /root/shadowducks-by-netfreer/shadowducks-server/target/shadowducks-server-1.0-SNAPSHOT-jar-with-dependencies.jar

Restart=always

[Install]

WantedBy=multi-user.target

然后运行：

systemctl start shadowducks

systemctl enable shadowducks

服务器端搭建完成。

至于客户端，兼容各大平台下的ss客户端程序。把4个参数填入即可。
