测试两台主机是否能通信 ping ip地址

[email?protected]:~$ ping 192.168.237.1
PING 192.168.237.1 (192.168.237.1) 56(84) bytes of data.

　　ping ip地址 -c 4? 　　ping4次后就停止

[email?protected]:~$ ping 192.168.237.1 -c 4

　　可以用Ping查看是否能够连接internet

[email?protected]:~$ ping www.baidu.com -c 4

查看域名对应ip地址 nslookup 网址

[email?protected]:~$ nslookup www.baidu.com
Server:        222.246.129.80
Address:    222.246.129.80#53

Non-authoritative answer:
www.baidu.com    canonical name = www.a.shifen.com.
Name:    www.a.shifen.com
Address: 14.215.177.38
Name:    www.a.shifen.com
Address: 14.215.177.39
