If \fBperzone\fR is set, then the values reflect the local zone except as noted. Otherwise, the settings are for the entire system. Any restriction based on the \fBperzone\fR setting is noted for each option to which it applies. .sp .LP A non-global zone administrator can set all audit policy options except \fBperzone\fR and \fBahlt\fR. \fBperzone\fR and \fBahlt\fR apply only to the global zone; setting these policies requires the privileges of a global zone administrator. \fBperzone\fR and \fBahlt\fR are described under the \fB-setpolicy\fR option, below. .SH OPTIONS .ne 2 .na \fB\fB-aconf\fR\fR .ad .sp .6 .RS 4n Set the non-attributable audit mask to the value set using the \fB-setnaflags\fR option. For example: .sp .in +2 .nf # auditconfig -aconf Configured non-attributable event mask. .fi .in -2 .sp .RE .sp .ne 2 .na \fB\fB-audit\fR \fIevent\fR \fIsorf\fR \fIretval\fR \fIstring\fR\fR .ad .sp .6 .RS 4n This command constructs an audit record for audit event \fIevent\fR using the process's audit characteristics containing a text token \fIstring\fR. The return token is constructed from the \fIsorf\fR (success/failure flag) and the \fIretval\fR (return value). The event is type \fBchar*\fR, the \fIsorf\fR is 0/1 for success/failure, \fIretval\fR is an errno value, \fIstring\fR is type \fB*char\fR. This command is useful for constructing an audit record with a shell script. An example of this option: .sp .in +2 .nf # auditconfig -audit AUE_ftpd 0 0 "test string" # audit record from audit trail: header,76,2,ftp access,,Fri Dec 08 08:44:02 2000, + 669 msec subject,abc,root,other,root,other,104449,102336,235 197121 elbow text,test string return,success,0 .fi .in -2 .sp .RE .sp .ne 2 .na \fB\fB-chkaconf\fR\fR .ad .sp .6 .RS 4n Checks that the current non-attributable event flags set in the kernel matches the configuration.

For example: .sp .in +2 .nf # auditconfig -getauid audit id = abc(666) .fi .in -2 .sp .RE .sp .ne 2 .na \fB\fB-getcar\fR\fR .ad .sp .6 .RS 4n Prints current active root location (anchored from root [or local zone root] at system boot).

The condition displayed is the literal string \fBauditing\fR meaning auditing is enabled and turned on (the kernel audit module is constructing and queuing audit records); \fBnoaudit\fR, meaning auditing is enabled but turned off (the kernel audit module is not constructing and queuing audit records); or \fBnospace\fR, meaning there is no space for saving audit records. See \fBauditon\fR(2) and \fBauditd\fR(8) for further information. .RE .sp .ne 2 .na \fB\fB-getcwd\fR\fR .ad .sp .6 .RS 4n Prints current working directory (anchored from zone root at system boot). For example: .sp .in +2 .nf # cd /usr/tmp # auditconfig -getcwd current working directory = /var/tmp .fi .in -2 .sp .RE .sp .ne 2 .na \fB\fB-getestate\fR \fIevent\fR\fR .ad .sp .6 .RS 4n For the specified event (string or event number), print out classes \fIevent\fR has been assigned.

The \fBahlt\fR and \fBperzone\fR policies reflect the settings from the global zone. If \fBperzone\fR is set, all other policies reflect the local zone's settings.
