1)系统安装时间

passwd -S root

[(27) root@Fedora~]#passwd -S root

root PS 2017-05-27 0 99999 7 -1 (密码已设置，使用SHA512算法)

输出信息：

root：代表查询的用户

PS:表示已经存在密码或者已经被锁。NP 表示没有密码 LK 表示用户被锁

2017-05-27 ：表示上次用户密码更改时间

0 ：密码更改最小日期

99999 ：密码更改最大日期

7 ：密码过期提醒期限

-1 ：密码过期后仍可使用的时间

原文：

-S Report password status on the named account. The first part

indicates if the user account is locked (LK), has no password

(NP), or has an existing or locked password (PS). The second

part gives the date of the last password change. The next parts

are the minimum age, maximum age, warning period, and inactivity

period for the password.

2)查询MAC

[(33) root@Fedora~]#ifconfig

enp2s0: flags=4163 mtu 1500

inet 10.20.41.182 netmask 255.255.0.0 broadcast 10.20.255.255

inet6 fe80::223:9eff:fe03:da00 prefixlen 64 scopeid 0x20

ether 00:23:9e:03:da:00 txqueuelen 1000 (Ethernet)

RX packets 1148342 bytes 300679175 (286.7 MiB)

RX errors 0 dropped 0 overruns 0 frame 0

TX packets 877017 bytes 302273584 (288.2 MiB)

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

device interrupt 3

其中ether就是MAC地址

查询mac地址第二种方法：

lshw -c network

[(32) root@Fedora~]#lshw -c network

3)查询硬盘序列号：
