linux

使用dmidecode

CPU ID
// 代码:
sudo dmidecode -t 4 | grep ID
// 主板序列号
代码:
sudo dmidecode -t 2 | grep Serial
// MAC地址
代码:
sudo lshw -c network | grep serial | head -n 1

这个需要使用root权限,同时对于jetson 板子,dmidecode没用

14、获取CPU序列号或者主板序列号

sudodmidecode –t 4 | grep ID



15、查看序列号:

sudodmidecode | grep Serial | more



16、查看cpu

sudodmidecode –t 4 | more



17、查看BIOS信息

sudodmidecode –t 0 | more



18、查看主板信息

sudodmidecode –t 2 | more



19、查看OEM

Sudodmidecode –t 11 | more



20、显示当前内存大小

free –m| grep “Mem” | awk ‘{print $2}’



21:显示系统运行时间

uptime



22:查看内核限制

23:查看Ubuntu版本信息

cat /etc/issue

或 cat/etc/lsb-release

或 lsb_release–dsc



24:查看系统是32位还是64位

#查看long的位数,返回32或64

getconf LONG_BIT

#查看文件信息,包含32-bit就是32位,包含64-bit就是64位

file /sbin/init

linux使用dmidecode代码获取主板序列号

获取CPUID:

CPUID并不是所有的Intel CPU都支持的。如果支持,汇编调用为:eax置0000_0003,调用cpuid。
以下为实现代码(在我的CPU上,并没有得到):

#define cpuid(in,a,b,c,d)  asm("cpuid": "=a" (a), "=b" (b), "=c" (c), "=d" (d) : "a" (in));
 
static int getcpuid (char *id, size_t max)
{
    int i;
    unsigned long li, maxi, maxei, ebx, ecx, edx, unused;
 
    cpuid (0, maxi, unused, unused, unused);
    maxi &= 0xffff;
 
    if (maxi < 3)
    {
        return -1;
    }
 
    cpuid (3, eax, ebx, ecx, edx);
 
    snprintf (id, max, "%08lx %08lx %08lx %08lx", eax, ebx, ecx, edx);
    fprintf (stdout, "get cpu id: %s/n", id);
 
    return 0;

rebuild : clean build

编译:make 或者 make build

运行:make run 或者 sudo make run (上面大多数信息都需要超级用户权限才能获取到结果)

清理:make clean (这个写得太死了,本来是想删除非cpp文件的,shell写不出来)

重编:make rebuild

命令行:

查看主机序列号:

C:\Users\Administrator>wmic bios get serialnumber
SerialNumber
WB12345678-------->>>>这是我笔记本的主机序列号,在不换主板的情况下,该序列号应该与机器机身上贴的序列号一致
 
C:\Users\Administrator>

查看磁盘序列号:

一、查看ECS实例中块存储的设备名
lsblk
在这里插入图片描述

二、使用以下命令获取块存储设备的序列号

udevadm info --query=all --name=磁盘设备名 | grep ID_SERIAL

例如

udevadm info --query=all --name=/dev/vda | grep ID_SERIAL

在这里插入图片描述
##获取CPU序列号

C:\Users\jesson>wmic CPU get ProcessorID
ProcessorId

获取mac地址和ip信息

一台机器上可能不只有一个网卡,但每一个网卡只有一个MAC地址,而每一个网卡可能配置有多个IP地址;如平常的笔记本电脑中,就会有无线网卡和有线网卡(网线接口)两种;因此,如果要获得本机所有网卡的IP和MAC地址信息,则必须顺序获得每个网卡,再依次获取其信息等;在windows sdk中,用IP_ADAPTER_INFO结构体存储网卡信息,包括网卡名、网卡描述、网卡MAC地址、网卡IP等,该结构体的主要描述如下所示:

typedef struct _IP_ADAPTER_INFO {
struct _IP_ADAPTER_INFO* Next;//指向链表中下一个适配器信息的指针
DWORD ComboIndex;//预留值
char AdapterName[MAX_ADAPTER_NAME_LENGTH + 4];//使用ANSI字符串表示的适配器名称
char Description[MAX_ADAPTER_DESCRIPTION_LENGTH + 4];//使用ANSI字符串表示的适配器描述
UINT AddressLength;//适配器硬件地址以字节计算的长度
BYTE Address[MAX_ADAPTER_ADDRESS_LENGTH];//硬件地址以BYTE数组所表示
DWORD Index;//适配器索引
    UINT Type;//适配器类型,主要有以下几种:
    /*
     *   MIB_IF_TYPE_OTHER     1
     *   MIB_IF_TYPE_ETHERNET     6
     *   MIB_IF_TYPE_TOKENRING     9
     *   MIB_IF_TYPE_FDDI     15
     *   MIB_IF_TYPE_PPP     23
     *   MIB_IF_TYPE_LOOPBACK      24
     *   MIB_IF_TYPE_SLIP      28
     */
UINT DhcpEnabled;//指定这个适配器是否开启DHCP
PIP_ADDR_STRING CurrentIpAddress;//预留值
IP_ADDR_STRING IpAddressList;//该适配器的IPv4地址链表
IP_ADDR_STRING GatewayList;//该适配器的网关IPv4地址链表
IP_ADDR_STRING DhcpServer;//该适配器的DHCP服务器的IPv4 地址链表
BOOL HaveWins;
IP_ADDR_STRING PrimaryWinsServer;
IP_ADDR_STRING SecondaryWinsServer;
time_t LeaseObtained;
time_t LeaseExpires;
} IP_ADAPTER_INFO,*PIP_ADAPTER_INFO;

由于可能有多个网卡,因此struct _IP_ADAPTER_INFO* Next字段为一个链表结构指针,由于一个网卡可能有多个IP,因此IP_ADDR_STRING字段应该也是一个链表结构,其信息如下所示:

typedef struct _IP_ADDR_STRING
{
    struct _IP_ADDR_STRING* Next;  //指向同类型节点,即下一个IP(如果有多IP的话)
    IP_ADDRESS_STRING IpAddress;  //IP地址信息
    IP_MASK_STRING IpMask; //IP子网掩码
    DWORD Context;// 网络表入口。这个值对应着AddIPAddredd和DeleteIPAddress函数中的NTEContext参数
} IP_ADDR_STRING;

由于可能有多个网卡,因此struct _IP_ADAPTER_INFO* Next字段为一个链表结构指针,由于一个网卡可能有多个IP,因此IP_ADDR_STRING字段应该也是一个链表结构,其信息如下所示:

typedef struct _IP_ADDR_STRING
{
    struct _IP_ADDR_STRING* Next;
