tnchkdb - check file syntax of trusted network databases


/usr/sbin/tnchkdb [-h path] [-t path] [-z path]


tnchkdb checks the syntax of the tnrhtp, tnrhdb, and tnzonecfg databases.
By default, the path for each file is:

o /etc/security/tsol/tnrhtp

o /etc/security/tsol/tnrhdb

o /etc/security/tsol/tnzonecfg

You can specify an alternate path for any or all of the files by
specifying that path on the command line by using the -h (tnrhdb), -t
(tnrhtp) and -z (tnzonecfg) options. The options are useful when testing
a set of modified files before installing the files as new system

All three database files are checked for integrity. tnchkdb returns an
exit status of 0 if all of the files are syntactically and, to the extent
possible, semantically correct. If one or more files have errors, then an
exit status of 1 is returned. If there are command line problems, such as
an unreadable file, an exit status of 2 is returned. Errors are written
to standard error.

To avoid cascading errors, when there are errors in tnrhtp, the template
names in tnrhdb are not validated.

tnchkdb can be run at any label, but the standard /etc/security/tsol
files are visible only in the global zone.


-h [ path ]
Check path for proper tnrhdb syntax. If path is not
specified, then check /etc/security/tsol/tnrhdb.

-t [ path ]
Check path for proper tnrhtp syntax. If path is not
specified, then check /etc/security/tsol/tnrhtp.

-z [ path ]
Check path for proper tnzonecfg syntax. If path is not
specified, then check /etc/security/tsol/tnzonecfg.


Example 1: Sample Error Message

The tnchkdb command checks for CIPSO errors. In this example, the
admin_low template has an incorrect value of ADMIN_HIGH for its default

# tnchkdb
checking /etc/security/tsol/tnrhtp ...
tnchkdb: def_label classification 7fff is invalid for cipso labels:
line 14 entry admin_low
tnchkdb: def_label compartments 241-256 must be zero for cipso labels:
line 14 entry admin_low
checking /etc/security/tsol/tnrhdb ...
checking /etc/security/tsol/tnzonecfg ...

How to Check the Syntax of Trusted Network Databases in Solaris Trusted
Extensions Administrator's Procedures


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

It is possible to have inconsistent but valid configurations of tnrhtp
and tnrhdb when LDAP is used to supply missing templates.
