NAME

SYNOPSIS

11       tpm_setactive [OPTION]
12
13

DESCRIPTION

15       tpm_setactive reports the status of the TPM's flags regarding the
16       active state of the TPM.  This is the default behavior and also
17       accessible via the --status option. Requesting a report of this status
18       prompts for the owner password.  The --active option changes the TPM to
19       the active state (via the TPM_PhysicalSetDeactivated API).  This
20       operation requires evidence of physical presence, is persistent and
21       requires a reboot to take affect. The --inactive option (via the
22       TPM_PhysicalSetDeactivated API) changes the TPM to the inactive state.
23       This operation requires evidence of physical presence, is persistent
24       and requires a reboot to take affect.  An inactive TPM is essentially
25       off but still allows for a tpm_takeownership to occur.  The --temp
26       option causes deactivation (via the TPM_SetTempDeactivated API) to
27       happen immediately but only endure for the current boot cycle.  The
28       --status, --active, --inactive, and --temp options are mutually
29       exclusive and the last one on the command line will be carried out.

32       -h, --help
33              Display command usage info.
34
35       -v, --version
36              Display command version info.
37
38       -l, --log [none|error|info|debug]
39              Set logging level.
40
41       -u, --unicode
42              Use TSS UNICODE encoding for passwords to comply with
43              applications using TSS popup boxes
44
45       -s, --status
46              Report the status of flags regarding the TPM active states.
47
48       -a, --active
49              Make the TPM active.  Operation is persistent, requires phyiscal
50              presence to authorize, and a reboot to take affect.
51
52       -i, --inactive
53              Make the TPM inactive.   Operation is persistent, requires
54              phyiscal presence to authorize, and a reboot to take affect.
55
56       -t, --temp
57              Makes the TPM inactive for the current boot cycle only.
58
59       -z, --well-known
60              Authenticate using 20 bytes of zeros as owner password (the
61              default TSS Well Known Secret), instead of prompting for an
62              owner password.
