Linux系统使用ping命令判断网络好坏

在Linux系统中如果要像判断网络是否好坏可以使用ping命令，ping命令是最常用的网络命令，可以测试与目标主机的连通性。下面良许教程网为大家详细讲解一下Linux系统如何使用ping命令判断网络好坏。

命令格式

ping [参数] [主机名或者IP地址]

使用范例

不加任何参数

如果不加任何参数，查看是否ping通

 ➜  ~ ping www.baidu.com    
 PING www.a.shifen.com (115.239.210.27) 56(84) bytes of data.
 64 bytes from 115.239.210.27: icmp_seq=1 ttl=52 time=6.06 ms
 64 bytes from 115.239.210.27: icmp_seq=2 ttl=52 time=5.56 ms

 --- 192.168.254.44 ping statistics ---
 5 packets transmitted, 5 received, 0% packet loss, time 3999ms
 rtt min/avg/max/mdev = 0.152/0.159/0.172/0.017 ms

发送指定数目

可以通过 参数-c 来发送指定数目的包后停止

 ➜ ~ ping www.baidu.com -c 5
 
 PING www.a.shifen.com (115.239.211.112) 56(84) bytes of data.

设定发送间隔

可以通过 参数 -c 数目：在发送指定数目的包后停止

 ➜ ~ ping www.baidu.com -c 5 -i 2
 
 PING www.a.shifen.com (115.239.211.112) 56(84) bytes of data.
