kcptun+shadowsocks

因为种种原因,自己的几个ss/ssr服务基本都失联了,最近被推荐了kcptun,原来觉得kcptun只是用于加速,没想到由于它本身的设计,现在居然可以用于绕过高墙。

一、服务端

首先配置ss:

$ pip install shadowsocks # 如果安完之后找不到ssserver,sudo之后可以解决;
$ ssserver -p [SS_PORT] -k [SS_KEY] -m [ENRYPT_METHOD] --user nobody -d start
如果报了Exception: libsodium not found:
$ wget https://download.libsodium.org/libsodium/releases/LATEST.tar.gz
$ tar zxf LATEST.tar.gz
$ cd libsodium-stable
$ ./configure
$ sudo make && sudo make install

如果依然报错,su之后;

$ echo /usr/local/lib > /etc/ld.so.conf.d/usr_local_lib.conf
$ ldconfig

然后配置kcptun:

$ wget https://raw.githubusercontent.com/kuoruan/kcptun_installer/master/kcptun.sh
$ chmod +x ./kcptun.sh
$ ./kcp.sh
在中文说明的引导下设置好各种参数,最后:

二、客户端

1.CLI

以MacOS下为例: 从原repo的releases页https://github.com/xtaci/kcptun/releases 获取kcptun的可执行文件

$ ./client_darwin_amd64 -l :xxx -r xx.xx.xx.xx:xxxxx --key xxxx --crypt xxxx --mode xxxx

2.Windows GUI

获取GUI客户端kcptun本体exe

在GUI客户端中进行配置,如图: 配置完成点击启动;

然后在Shadowsocsk的客户端中添加一个新的服务器,ip填127.0.0.1,端口填上面的“本地侦听端口”,其他参数与服务端的ss配置一致,配置完成启动即可;

3.Android

在Play Store中下载Shadowsocks和kcptun,在Shadowsocks中填加一个新的服务器配置,ip填服务器ip,端口填服务端的kcp端口,其他和ss配置一致,在下方的Plugin设置中选择kcptun,参数仿照默认格式填写即可;
