System Administration Commands tnd(1M)
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 con-
figuration 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 net-
work 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 ini-
tiate 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:

System Administration Commands tnd(1M)
tnd/debuglevel = 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/pollinterval=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 facil-
ity, 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
