测试两台主机是否能通信 ping ip地址
sailfish@DESKTOP-GSV91L5:~$ ping 192.168.237.1 PING 192.168.237.1 (192.168.237.1) 56(84) bytes of data. 64 bytes from 192.168.237.1: icmp_seq=1 ttl=128 time=0.207 ms 64 bytes from 192.168.237.1: icmp_seq=2 ttl=128 time=0.202 ms 64 bytes from 192.168.237.1: icmp_seq=3 ttl=128 time=0.194 ms 64 bytes from 192.168.237.1: icmp_seq=4 ttl=128 time=0.192 ms ^C --- 192.168.237.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3002ms rtt min/avg/max/mdev = 0.192/0.198/0.207/0.018 ms
ping ip地址 -c 4 ping4次后就停止

可以用Ping查看是否能够连接internet
