JAVA supports cross-platform access to cpuid, motherboard ID, hard disk ID, and MAC address (compatible with Windows and Linux)

Windows:

 Linux:

Command:

0. View cpuid: dmidecode-T processor | grep 'id'

1. view the server model:Dmidecode | grep 'product name'

2. view the serial number of the motherboard:Dmidecode | grep 'serial number'

3. view the system serial number:Dmidecode-S system-serial-Number

4. view memory information:Dmidecode-T memory

5. View OEM information:Dmidecode-T 11
