如何获取我的linux系统的先前主机名？

Question

我不小心将系统更改为主机名.现在我想将其更改为我以前的主机名.但我不知道以前的主机名.

Answer 1

看看这些文件:

/etc/hostname
/etc/hosts
/etc/ssh/ssh_host_*_key.pub
$HOME/.ssh/id_*.pub

在这些通常会显示主机名,并且您的重命名操作可能仍然保持不变(但是您这样做了).

这些也可能包含旧名称:

/var/log/Xorg.failsafe.log
/var/log/auth.log.1
/var/log/pm-suspend.log.1
/var/log/Xorg.1.log.old
/var/log/lightdm/x-0.log
/var/log/lightdm/x-1.log
/var/log/lightdm/x-2.log
/var/log/pm-suspend.log
/var/log/Xorg.0.log.old
/var/log/Xorg.1.log
/var/log/syslog
/var/log/Xorg.2.log
/var/log/auth.log
/var/log/kern.log.1
/var/log/kern.log
/var/log/Xorg.failsafe.log.old
/var/log/syslog.1
/var/log/Xorg.0.log
