TPM2-ABRMD(8)

NAME
tpm2-abrmd - TPM2 access broker and resource management daemon

SYNOPSIS
tpm2-abrmd [-c][-o][-l logger-name][-r][-s][-p /dev/urandom][-t tcti-name] [tcti-specific-options]

DESCRIPTION
tpm2-abrmd is a daemon that implements the TPM access broker and resource manager as described by the Trusted Computing Group (TGC) in the “TSS System Level API and TPM Command Transmission Interface Specification”. This daemon uses the DBus system bus and some pipes to communicate with clients.

OPTIONS

-c, --max-connections
    Set an upper bound on the number of concurrent client connections allowed. Once this number of client connections is reached new connections will be rejected with an error.

-o, --fail-on-loaded-trans
    Cause the daemon to fail on startup when the TPM is found to already have transient objects loaded. This is intended as a safe-guard to keep the daemon from stomping on the TPM state setup by another process.

-l, --logger
    Direct logging output to named logging target. Supported targets are stdout and syslog. If the logger option is not specified the default is stdout.

-r, --max-transient-objects
    Set an upper bound on the number of transient objects that each client connection allowed to load. Once this number of objects is reached attempts to load new transient objects will produce an error.

-n, --dbus-name
    Claim the given name on dbus. This option overrides the default of com.intel.tss2.Tabrmd.

-p, --prng-seed-file
    Read seed for pseudo-random number generator from the provided file.

-s, --session
    Connect daemon to the session dbus. This option overrides the default behavior.

-t, --tcti
    Select the TCTI used by tabd for communication with the next component down the TSS stack. In most configurations this will be the TPM but it could be a simulator or proxy. Supported TCTIs are “none” .

-v, --version
    Disply version string.
