 TNCTL 8 "May 13, 2017"
 NAME
tnctl - configure Trusted Extensions network parameters
 SYNOPSIS

/usr/sbin/tnctl [-dfv] [-h host [/prefix] [:template]]
 [-m zone:mlp:shared-mlp][-t template [:key=val [;key=val]]]
 [-HTz] file]


 DESCRIPTION

tnctl provides an interface to manipulate trusted network parameters in
the Solaris kernel.

As part of Solaris Trusted Extensions initialization, tnctl is run in the
global zone by an smf(7) script during system boot. The tnctl
command is not intended to be used during normal system administration.
Instead, if a local trusted networking database file is modified,
the administrator first issues
tnchkdb(8) to check the syntax, and then refreshes the kernel copy with
this command:
# svcadm restart svc:/network/tnctl


See WARNINGS about the risks of changing remote host and template
information on a running system.
 OPTIONS
-d

Delete matching entries from the kernel. The default is to add new entries.
When deleting MLPs, the MLP range must match exactly. MLPs are specified in the
form:
port[-port]/protocol


Where port can be a number in the range 1 to 65535. or any known service
(see services(5)), and protocol can be a number in the range 1 to 255, or
any known protocol (see protocols(5)).


-f

Flush all kernel entries before loading the entries that are specified on the
command line. The flush does not take place unless at least one entry parsed
successfully.


-v

Turn on verbose mode.


-h host[/prefix][:template]

Update the kernel remote-host cache on the local host for the specified
host or, if a template name is given, change the kernel's cache to use
the specified template. If prefix is not specified, then an implied
prefix length is determined according to the rules used for interpreting the
tnrhdb. If -d is specified, then a template name cannot be
specified.


-m zone:mlp:shared-mlp

Modify the kernel's multilevel port (MLP) configuration cache for the specified
zone. zone specifies the zone to be updated. mlp and
shared-mlp specify the MLPs for the zone-specific and shared IP
addresses. The shared-mlp field is effective in the global zone only.


-t template[key=val[;key=val]]

Update the kernel template cache for template or, if a list of
key=val pairs is given, change the kernel's cache to use the specified
entry. If -d is specified, then key=val pairs cannot be specified.


-T file

Load all template entries in file into the kernel cache.


-H file

Load all remote host entries in file into the kernel cache.


-z file

Load just the global zone's MLPs from file into the kernel cache. To
reload MLPs for a non-global zone, reboot the zone:
# zoneadm -z non-global zone reboot

 WARNINGS

Changing a template while the network is up can change the security view of an
undetermined number of hosts.
 NOTES

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

The tnctl service is managed by the service management facility,
smf(7), under the service identifier:
svc:/network/tnctl


The service's status can be queried by using svcs(1). Administrative
actions on this service, such as refreshing the kernel cache, can be performed
using svcadm(8), as in:
svcadm restart svc:/network/tnctl
