如何刷新本地IP地址？

Question

如何刷新ip a命令在inet附近看到的当前本地IP地址？问题是，有时我从交换机连接电缆，然后IP发生变化。

它似乎改变了，因为每当我将它连接到交换机时，我就不能再使用ssh了(超时)

*这个交换机实际上是我用来做交换机的旧路由器

Answer 1

忘记IP，使用ssh user_name@host_name.local连接到名为host_name的机器。它将解决您的IP更改问题。

MacUser2525:~$ alias pi
alias pi='ssh zeus@buster-raspi.local'
MacUser2525:~$ pi
Linux buster-raspi 5.9.0-0.bpo.5-arm64 #1 SMP Debian 5.9.15-1~bpo10+1 (2020-12-31) aarch64
