  • 严格的所有权检查

    • 所有权 /home/admin 并且所有内容都必须是 admin:admin。
    • SSH 材料（例如， /home/admin/.ssh/authorized_keys、密钥）必须归所有 admin 并有严格的烫发（没有为团体/其他人写）。
    • 一些脚本和运行时状态写入 /home/admin 必须可通过 admin 用户，不归 root。

    改变 root:admin，dpncheck/cprecovery 检测 意外的所有权 并作为安全措施进行救助。

  • 谈判者/管理层对管理员家
    的依赖性 Avamar 协商器 和管理守护程序依赖于 admin 用于身份验证和业务流程的帐户上下文。如果文件位于 /home/admin 不归所有方 admin，您可以看到：

    • SSH 身份验证失败或由于不安全的权限而跳过执行。
    • 脚本在检测到错误的所有者时拒绝运行（深度防御）。
    • 导致的命令失败会冒泡，因为 MSG_ERR_CMD_FAIL.

# su -
