往期好文：麒麟KYSEC使用方法05-命令设置密码强度
hello，大家好啊，今天给大家带来麒麟KYLINOS的kysec使用方法系列文章第六篇内容----使用命令设置账户锁定，账户锁定策略有一个文件需要修改，common-auth，今天给大家介绍一下使用命令设置账户锁定的文章，欢迎大家点个赞并点个在看。关注我吧！
1、查看系统信息
pdsyw@pdsyw-pc:~/桌面$ sudo -i
root@pdsyw-pc:~#
root@pdsyw-pc:~# cat /etc/.kyinfo
[dist]
name=Kylin
milestone=Desktop-V10-SP1-General-Release-2303
arch=arm64
beta=False
time=2023-04-27 15:46:53
dist_id=Kylin-Desktop-V10-SP1-General-Release-2303-arm64-2023-04-27 15:46:53
[servicekey]
key=0516013
[os]
to=
term=2024-08-01
root@pdsyw-pc:~# uname -a
Linux pdsyw-pc 5.4.18-85-generic #74-KYLINOS SMP Fri Mar 24 11:20:19 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux
root@pdsyw-pc:~#
2、查看common-auth原文件
root@pdsyw-pc:~# cat /etc/pam.d/common-auth
#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules. See
# pam-auth-update(8) for details.
# here are the per-package modules (the "Primary" block)
auth [success=3 default=ignore] pam_biometric.so
auth [success=2 default=ignore] pam_unix.so nullok_secure try_first_pass pwquality deny=5 unlock_time=180 root_unlock_time=180
auth [success=1 default=ignore] pam_sss.so use_first_pass
# here's the fallback if no module succeeds
auth requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
auth required pam_permit.so
# and here are more per-package modules (the "Additional" block)
# end of pam-auth-update config
root@pdsyw-pc:~#
3、查看账户锁定的策略情况
4、更改密码连续输错次数为10次
root@pdsyw-pc:~# sed -i 's/deny=5/deny=10/g' /etc/pam.d/common-auth
root@pdsyw-pc:~#
root@pdsyw-pc:~# grep deny /etc/pam.d/common-auth
auth [success=2 default=ignore] pam_unix.so nullok_secure try_first_pass pwquality deny=10 unlock_time=180 root_unlock_time=180
auth requisite pam_deny.so
root@pdsyw-pc:~#
5、更改后的情况
6、更改账户锁定时间为5分钟
root@pdsyw-pc:~# sed -i 's/unlock_time=180/unlock_time=300/g' /etc/pam.d/common-authroot@pdsyw-pc:~#
root@pdsyw-pc:~# grep unlock_time /etc/pam.d/common-auth
auth [success=2 default=ignore] pam_unix.so nullok_secure try_first_pass pwquality deny=10 unlock_time=300 root_unlock_time=300
root@pdsyw-pc:~#
7、更改后的情况
