IPerf简单使用

一 点睛

1 IPerf是一个服务器/客户端运行的程序

2 在服务器端运行iPerf，也需要在客户端运行IPerf。

3 服务器端，在命令行下使用iperf加参数-s。

4 客户端，在命令行下使用iperf加参数-c。

5 经过一段时间测试（默认10秒），在Server端和Client端就会打印出网络连接的各种性能参数。

二 实战

1 准备服务器和客户端

服务器：192.168.0.110

客户端：192.168.0.120

2 确保服务器和客户端都关闭了防火墙

[root@localhost iperf-1.7.0]# firewall-cmd --state not running

3 启动服务端

[root@localhost iperf-1.7.0]# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------

4 运行客户端

[root@localhost iperf-1.7.0]# iperf -c 192.168.0.110 ------------------------------------------------------------ Client connecting to 192.168.0.110, TCP port 5001 TCP window size: 85.0 KByte (default) ------------------------------------------------------------

5 此时服务端打印如下

[root@localhost iperf-1.7.0]# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 85.3 KByte (default) ------------------------------------------------------------ [ 4] local 192.168.0.110 port 5001 connected with 192.168.0.120 port 39046
