Symptoms

描述

在启用了“密码哈希值”功能的情况下导入 iDRAC 用户属性后，iDRAC 可能会停止接受远程 IPMI 命令。

Error: Unable to establish IPMI v2 / RMCP+ session

Dell EMC iDRAC 增加了对通过哈希值和盐值配对来导入 iDRAC 用户密码的支持。此功能可在导入 iDRAC 用户帐户时提供更多一层的安全保护。有几种常见的方法可以通过哈希密码导出和导入 iDRAC 用户密码，这些方法可能会导致此行为：
 

  • 服务器配置文件导出/导入（可选）
  • 使用哈希密码创建 RACADM CLI iDRAC 用户（可选）
  • Redfish CLI 使用哈希密码创建 iDRAC 用户（可选）
  • 更换系统主板后的轻松还原功能（可选）

Cause

Dell EMC iDRAC9 在产品初次推出时引入了遮挡明文用户密码的新功能。当利用 iDRAC 用户密码的加盐哈希值时，需要 Dell OEM IPMITOOL 来解析哈希密码值。  

Resolution

解决方案

“密码哈希值”功能需要支持的 Dell EMC IPMItool 版本才能正确处理加密的哈希密码。为支持哈希密码加密，请至少使用以下 BMC 工具集内捆绑的 Dell EMC IPMITOOL 版本：
 


Dell EMC 对 IPMItool 的更改已提交至开放源代码社区。某些 Linux 发行版本可能会利用尚未支持此更改的较新版本的 IPMItool。

恢复：

如果无意中将 HASH 密码应用于 iDRAC 用户帐户，则使用明文覆盖用户密码将允许第三方 IPMI 工具重新连接。
