24 Troubleshooting CCTK
Running CCTK on Linux
When you install CCTK on a Linux system, the entry, modprobe dcdbas,
is added in the /etc/rc.modules file. After uninstalling CCTK, this entry
will not be removed.
TPM Activation
Trusted Platform Module (TPM) is an industry standard cryptographic
module that provides attestation, integrity metrics and reporting, and a
secure key hierarchy. Dell client systems use TPM to verify if the state of the
system has changed between two boot cycles.
To activate and check the TPM activation:
1
If not set, set the BIOS password on the system.
cctk --setuppwd=<new-BIOS-password>
2
If not enabled, enable TPM.
cctk --tpm=on
3
Reboot the system.
4 Activate TPM.
cctk --tpmactivation=activate --valsetuppwd=<BIOS-
password>
5
Reboot the system without interruption till the operating system loads.
6 Check the status of TPM.
cctk --tpmactivation
The status is displayed as activate.
