LinuxDMIDDecodeHardwareInfo
f you need to know what hardware your computer or server has without having physical access to the machine, you can look it up using a Linux command called dmidecode.
A couple of weeks ago I had to find out the product and model of my HP server. I knew it was an HP Proliant DL 360 but didn’t know if it was a G3, G4, G5 or G6. By using dmidecode we extract this information:
[root@mylinuxserver /]# dmidecode --type 1
- dmidecode 2.10
SMBIOS 2.3 present.
Handle 0x0100, DMI type 1, 25 bytes System Information Manufacturer: HP Product Name: ProLiant DL360 G4p Version: Not Specified Serial Number: xxxxxxxx UUID: xxxxxxxx Wake-up Type: Power Switch
There are a lot of options you can use with dmidecode to extract all the information you want. Just take a look at the following list:
