我在 Ubuntu 机器上测试了以下内容。
命令
ping play
结果是
PING play (127.0.53.53) 56(84) bytes of data.
64 bytes from 127.0.53.53: icmp_seq=1 ttl=64 time=0.029 ms
64 bytes from 127.0.53.53: icmp_seq=2 ttl=64 time=0.036 ms
64 bytes from 127.0.53.53: icmp_seq=3 ttl=64 time=0.032 ms
64 bytes from 127.0.53.53: icmp_seq=4 ttl=64 time=0.030 ms
如果我执行以下操作：
ssh play
我可以登录到我自己的机器localhost。
最后，以下内容：
dig play
结果是：
