NAME

       tnd - trusted network daemon

SYNOPSIS

       /usr/sbin/tnd  [-p poll-interval]

DESCRIPTION

       The  tnd  (trusted  network  daemon) initializes the kernel with trusted network databases and also reloads the databases on demand from an
       LDAP server and local files.  tnd follows the order specified in the nsswitch.conf  file  when  loading	configuration  databases.  tnd	is
       started at the beginning of the boot process.

       tnd  loads  two	databases into the kernel: the remote host database, tnrhdb and the remote-host template database, tnrhtp. These databases
       and their effect on the trusted network are described in their respective man pages. When the associated LDAP database or  local  databases
       are changed, tnd also updates the local kernel cache at the predetermined interval.

       If  a local trusted networking database file is modified, the administrator should run tnchkdb(1M) to check the syntax, and should also run
       svcadm refresh svc:/network/tnd to initiate an immediate database scan by tnd.

       tnd is intended to be started from an smf(5) script and to run in the global zone. The following signals cause specific svcadm actions:

       SIGHUP	  Causes svcadm refresh svc:/network/tnd to be run.

		  Initiates a rescan of the local and LDAP tnrhdb and tnrhtp databases. tnd updates the kernel database with any changes found.

       SIGTERM	  Causes svcadm disable svc:/network/tnd to be run.

		  Terminates the tnd daemon. No changes are made to the kernel database.

       Running tnd in debug mode is determined by the value of the following service  management facility (SMF) property:

	 tnd/debug_level = 0

       A value of 0, as above, prevents debug information from being collected; 1 turns on debugging. The default value is  0.	 Debug	output	is
       sent to the /var/tsol/tndlog log file.

OPTIONS

       -p poll-interval    Set poll interval to poll-interval seconds. The default poll-interval is 1800 seconds (30 minutes).

EXAMPLES

       Example 1 Changing the Poll Interval

       The  following  command	changes  the polling interval to one hour, and puts this interval in the SMF repository. At the next boot, the tnd
       poll interval will be one hour.

	 # svccfg -s network/tnd setprop tnd/poll_interval=3600

       The following command changes the polling interval, but does not update the repository. At the next boot, the tnd poll interval remains the
       default, 30 minutes.

	 # tnd -p 3600

NOTES

       The functionality described on this manual page is available only if the system is configured with Trusted Extensions.

       The tnd service is managed by the service  management facility, smf(5), under the service identifier:

	 svc:/network/tnd

       The  service's status can be queried by using svcs(1). Administrative actions on this service,  such as requests to restart the daemon, can
       be performed using svcadm(1M), as in:

	 svcadm restart svc:/network/tnd
