Howdy, I've whipped together a very simple module for extracting some SMBIOS variables to define additional classes, here's some example output:
--------------------------------------------------------------------- Plug-in `module:smbios' --------------------------------------------------------------------- Exec module [/var/cfengine/modules/module:smbios ] Activated classes: smbios_vendor_Dell_Computer_Corporation Activated classes: smbios_model_PowerEdge_1850 Activated classes: smbios_serial_HC98D91 Activated classes: smbios_cpu0_Intel_Xeon_CPU_3_00GHz Activated classes: smbios_cpu1_Intel_Xeon_CPU_3_00GHz Activated classes: smbios_total_mem_4294967296 <snip> Exec module [/var/cfengine/modules/module:smbios ] Activated classes: smbios_vendor_SiMech Activated classes: smbios_model_Q300 Activated classes: smbios_serial_SM19974 Activated classes: smbios_cpu0_Intel_Xeon_CPU_3_00GHz Activated classes: smbios_cpu1_Intel_Xeon_CPU_3_00GHz Activated classes: smbios_total_mem_4294967296 This script requires lshw (Linux only, dmidecode port welcomed) and xmlstarlet for parsing. Also, most "whitebox" servers have a default serial # of "1234567890" etc; in theory this is not the case with modern HP, Dell, etc. motherboards. I'd appreciate comments and suggestions, thanks. -- Matt Peterson
