tcsd: configuration file for the trousers TCS daemon.

TCG Software Stack

NAME

tcsd.conf - configuration file for the trousers TCS daemon.

DESCRIPTION

This file, by default /etc/tcsd.conf is read by the trousers TCSD daemon, tcsd (see tcsd(8)). The tcsd.conf file that is installed by trousers contains all the default options, commented out.

OPTIONS

port The port that TCSD will listen on for connections, local and remote, from applications.

num_threads The maximum number of threads that the TCSD will spawn simultaneously to service applications. After num_threads threads have been spawned, any application that attempts to connect to the TCSD will receive an error.

system_ps_file The location of the system persistent storage file. The system persistent storage file holds keys and data across restarts of the TCSD and system reboots.

firmware_log_file Path to the file containing the current firmware PCR event log data. The interface to this log is usually provided by the TPM device driver.

kernel_log_file Path to the file containing the current kernel PCR event log data. By default, this data will be parsed in the format provided by the Integrity Measurement Architecture LSM.

firmware_pcrs A list of PCR indices that are manipulated only by the system firmware and therefore are not extended or logged by the TCSD. Applications that call Tcsi_PcrExtend on PCRs listed here will receive an error.

kernel_pcrs A list of PCR indices that are manipulated only by the kernel and therefore are not extended or logged by the TCSD. Applications that call Tcsi_PcrExtend on PCRs listed here will receive an error.

platform_cred Path to the platform credential for your TPM. Your TPM manufacturer may have provided you with a set of credentials (certificates) that should be used when creating identities using your TPM. When a user of your TPM makes an identity, this credential will be encrypted as part of that process. See the 1.1b TPM Main specification section 9.3 for information on this process.

conformance_cred Path to the conformance credential for your TPM. Your TPM manufacturer may have provided you with a set of credentials (certificates) that should be used when creating identities using your TPM. When a user of your TPM makes an identity, this credential will be encrypted as part of that process. See the 1.1b TPM Main specification section 9.3 for information on this process.

endorsement_cred Path to the endorsement credential for your TPM. Your TPM manufacturer may have provided you with a set of credentials (certificates) that should be used when creating identities using your TPM. When a user of your TPM makes an identity, this credential will be encrypted as part of that process. See the 1.1b TPM Main specification section 9.3 for information on this process.

remote_ops A list of TCS commands which will be allowed to be executed on this machine's TCSD by TSP's on non-local hosts (over the internet). By default, access to all operations is denied.

host_platform_class Determines the TCG specification of the host's platform class. This refers to one of the specifications contained in the TCG web site. The default is PC specification version 1.2 .

all_platform_classes Specifies all the TCG defined platforms associated with the host platform. The host_platform_class must not be defined here. By default, all platforms but the host platform are associated.

platform_cred = /var/lib/tpm/platform.cert
conformance_cred = /var/lib/tpm/conformance.cert
endorsement_cred = /var/lib/tpm/endorsement.cert
remote_ops = create_key,random
