TNCTL(1M) Maintenance Commands TNCTL(1M)


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(5) 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(1M) 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(4)), and protocol can be a number in the range
1 to 255, or any known protocol (see protocols(4)).


-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(5),
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(1M), as in:

svcadm restart svc:/network/tnctl
