Trusted Platform Module (TPM)
NOTE: For more information about the TPM, see developer.ubuntu.com/en/snappy/guides/security-whitepaper/.
TPM hardware is installed on products with Snappy-enhanced security support. TPM is supported only on these devices
that have the TPM hardware installed. The TPM on/off setting is configurable in the BIOS and manageable through the Dell
Command | Configure application in the operating system.
1. Verify if the TPM module has been loaded.
(plano)ubuntu@localhost:~$ ls /dev/tpm0
ls: cannot access /dev/tpm0: No such file or directory
2. If TPM is turned on, the device node (/dev/tpm0) exists.
# ls /dev/tpm0
Activate TPM in Dell Command | Configure
Follow these steps to check TPM activation in the Dell Command | Configure application.
1. If not set, set the BIOS password.
# cctk --setuppwd=<new-BIOS-password>
2. If not enabled, enable TPM.
# cctk --tpm=on
3. Reboot the system.
# systemctl reboot
4. Activate TPM.
# cctk --tpmactivation=activate --valsetuppwd=<Setuppwd>
5. Reboot the system.
# systemctl reboot
NOTE: Do not power off the system while it is rebooting.
6. Check whether TPM is active.
# cctk --tpmactivation
