TND(8) Maintenance Commands and Procedures TND(8)

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(8) 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(7) 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(7), 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(8), as in:

svcadm restart svc:/network/tnd
