FreeBSD CPU 序列号

我尝试从装有 FreeBSD 的服务器读取 CPU 序列号信息。

我毫不费力地尝试了这些：

  • 系统控制
  • 消息
  • CPU控制

系统上不存在这些实用程序：

  • 德米德码
  • 处理器信息
  • 处理器ID
  • /proc 目录

我无法在服务器上安装任何软件。

知道如何解决吗？

谢谢！

FreeBSD 上存在“cpuid”包，但它不是基础系统的一部分。

输出示例：

root@freeBSD > cpuid

我认为您要查找的值是“处理器序列”。因此，一个简单的cpuid |grep "Processor serial"方法就可以了。

正如您所说，您无法在服务器上安装某些东西，但您仍然可以：

  • 找到一个安静的地方/tmp（如果你想保持低痕迹/垃圾），

  • 获取预编译包：

    fetch ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages/misc/cpuid-3.3_6.tbz

    （使用您的服务器架构调整 URL - 请参阅uname -a以了解更多信息）

  • 从中提取“cpuid”二进制文件：

    tar -jxvf cpuid-3.3_6.tbz bin/cpuid`

  • 并在本地执行：

    ./bin/cpuid
