xkcptun主要应用于LEDE,openwrt中,其原理如图:
安装libevent2和json-c库后
git clone https://github.com/liudf0716/xkcptun.git
cd xkcptun
mkdir build && cd build
cmake ..
make
生成xkcp_client和xkcp_server
为方便理解和使用,我们将使用场景放在同一台pc上,pc使用ubuntu系统,我们通过xkcptun来访问本机的http server
假设pc的 eth0 ip 为 192.168.199.18, http server的监听端口为80端口,xkcptun的server和client配置分别如下:
server.json 如下:
{
"localinterface": "eth0",
"localport": 9089,
"remoteaddr": "192.168.199.18",
"remoteport": 80,
"key": "14789632a",
"crypt": "none",
"mode": "fast3",
"mtu": 1350,
"sndwnd": 1024,
"rcvwnd": 1024,
"datashard": 10,
"parityshard": 3,
"dscp": 0,
"nocomp": true,
"acknodelay": false,
"nodelay": 0,
"interval": 20,
"resend": 2,
"nc": 1,
"sockbuf": 4194304,
"keepalive": 10
}
client.json如下:
{
"localinterface": "eth0",
"localport": 9088,
"remoteaddr": "192.168.199.18",
"remoteport": 9089,
"key": "14789632a",
"crypt": "none",
"mode": "fast3",
"mtu": 1350,
"sndwnd": 1024,
"rcvwnd": 1024,
"datashard": 10,
"parityshard": 3,
"dscp": 0,
"nocomp": true,
"acknodelay": false,
"nodelay": 0,
"interval": 20,
"resend": 2,
"nc": 1,
"sockbuf": 4194304,
"keepalive": 10
}
分别运行:
xkcp_server -c server.json -f -d 7
xkcp_client -c client.json -f -d 7
curl http://192.168.199.18:9088
其执行效果与curl http://192.168.199.18 等同
