![CentOS access.conf 设置运行不正常?](https://linux22.com/image/798037/CentOS%20access.conf%20%E8%AE%BE%E7%BD%AE%E8%BF%90%E8%A1%8C%E4%B8%8D%E6%AD%A3%E5%B8%B8%EF%BC%9F.png)
我有一台 CentOS 机器,下面我在我的机器中设置了它access.conf
:
root : ALL
但是我可以通过 root 登录并执行任务。那么,它的工作是什么access.conf
?这里有什么问题吗?
答案1
在这里你可以了解如何激活 access.conf
我确实在 access.conf 文件中添加了以下内容
[root@lcoalhost ~]# tail -1 /etc/security/access.conf
-:user1:ALL
我在文件“/etc/pam.d/sshd”中添加了以下内容
[root@localhost ~]# head -3 /etc/pam.d/sshd
#%PAM-1.0
auth include system-auth
account required pam_access.so #I added this line in the file
特别是第三行。
编辑此内容后,我尝试以用户身份访问服务器:user1:
这是我在日志文件中看到的内容“/var/log/secure”
Jan 1 16:40:06 localhost sshd[17981]: pam_access(sshd:account): access denied for user `user1' from `10.0.1.243'
Jan 1 16:40:06 localhost sshd[17981]: Failed password for user1 from 10.0.1.243 port 3186 ssh2
Jan 1 11:10:06 localhost sshd[17982]: fatal: Access denied for user user1 by PAM account configuration
此处“user1”已被拒绝任何 IP。同样,您可以对任何用户执行此操作。
root
这是用户的日志
Jan 1 16:53:29 localhost sshd[19144]: pam_access(sshd:account): access denied for user `root' from `10.0.1.243'
Jan 1 16:53:29 localhost sshd[19144]: Failed password for root from 10.0.1.243 port 3356 ssh2
Jan 1 11:23:29 localhost sshd[19145]: fatal: Access denied for user root by PAM account configuration
希望这可以帮助。
