tnd(1M) System Administration Commands tnd(1M)NAMEtnd - 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 nss‐
witch.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 respec‐
tive man pages. When the associated LDAP database or local databases
are changed, tnd also updates the local kernel cache at the predeter‐
mined interval.
If a local trusted networking database file is modified, the adminis‐
trator 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 col‐
lected; 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
