- trusted network daemon
/usr/sbin/tnd [-p poll-interval]
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(4) file when loading configuration databases.
tnd is intended to be started from the svc:/network/tnd smf(5) service during the boot process in the global zone only when the system has been configured as an LDAP client. Systems that use only local files for the trusted network databases use tnctl(1M) instead of tnd.
tnd loads the following databases into the kernel: the remote host database, tnrhdb, and the remote-host template database, tnrhtp. tnd also periodically scans for changes in the associated LDAP database or local databases and updates the kernel cache accordingly.
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 svcadm commands signal tnd to perform specific actions:
Initiates a rescan of the local and LDAP tnrhdb and tnrhtp databases. tnd updates the kernel database with any changes found.
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.
Set poll interval to poll-interval seconds. The default poll-interval is 1800 seconds (30 minutes).
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

Configuration file for the name service switch
See attributes(5) for descriptions of the following attributes:

The command invocation is Committed. The service is Private.

Trusted Extensions Configuration and Administration
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
