如何在 Linux 中 ping 计算机？

Question

我已经通过 SSH 连接到一台运行 Linux 的机器，并想知道；在Linux中是否有任何命令可以ping计算机或将域名转换为IP地址？

Answer 1

"ping" 和 "nslookup" 假设你已经安装了 SSH 的机器：

you@yourhost:~$ ping www.google.com
PING www.l.google.com (173.194.37.104) 56(84) bytes of data.
64 bytes from lhr14s02-in-f104.1e100.net (173.194.37.104): icmp_seq=1 ttl=57 time=27.8 ms
64 bytes from lhr14s02-in-f104.1e100.net (173.194.37.104): icmp_seq=2 ttl=57 time=27.1 ms

you@yourhost:~$ nslookup www.google.com
Server:     192.168.1.1
Address:    192.168.1.1#53

Non-authoritative answer:
www.google.com  canonical name = www.l.google.com.
Name:   www.l.google.com
Address: 173.194.37.104
