cd netstrain-3.0;make //在当前目录下生成netstraind服务器端和netstrain客户端

//在被测试服务器上运行服务器端，指定ipv4和port

./netstraind -4 11111

//server端如果需要修改绑定本地的ip地址，修改netstrain-3.0目录下server.c 文件中setup_socket函数里第100行调用点的gai_error = getaddrinfo(NULL, portspec, &hints, &aitop);的第一个参数为gai_error = getaddrinfo("*.*.*.160", portspec, &hints, &aitop);重新编译启动即可

//在客户端运行，设置测试全双工，目标ip，port，ipv4

./netstrain -4 *.*.*.160 11111 both

//显示

[jrckkyy@localhost netstrain-3.0]$ ./netstrain -4 *.*.*.160 11111 both

总结：netstrain相对测试的功能简单，可以看到tcp单个连接来回上行下行的当前网络环境网速是多少，服务器客户端调换位置测试，上行下行网速跟之前测试是一致的。
