ping检查网络连通性

ping 常常用来测试与目的主机的连通性。

可以ping通

[root@chao~]#ping172.16.1.254PING172.16.1.254(172.16.1.254)56(84)bytesofdata.64bytesfrom172.16.1.254:icmp_seq=1ttl=128time=0.529ms64bytesfrom172.16.1.254:icmp_seq=2ttl=128time=0.297ms64bytesfrom172.16.1.254:icmp_seq=3ttl=128time=0.135ms64bytesfrom172.16.1.254:icmp_seq=4ttl=128time=0.245ms64bytesfrom172.16.1.254:icmp_seq=5ttl=128time=0.214ms^C---172.16.1.254pingstatistics---5packetstransmitted,5received,0%packetloss,time4001msrttmin/avg/max/mdev=0.135/0.284/0.529/0.133ms[root@chao~]#不可以ping通
