auditon -- enable auditing

Synopsis

auditon

Description

The auditon shell level command allows the administrator with the appropriate privileges to enable auditing. The privileges required are audit, dacread, macwrite and setplevel.

When auditon is invoked, it retrieves the default values for the AUDIT_LOGERR, AUDIT_LOGFULL, and AUDIT_DEFPATH parameters from the /etc/default/audit file. If access to the file is denied or if any of the key words is missing or invalid, an error message is printed (see ``Diagnostics''). The default value for the AUDIT_LOGERR and AUDIT_LOGFULL parameters is DISABLE. The default value for the AUDIT_DEFPATH parameter is /var/audit.

If the event log file is a regular file, the AUDIT_NODE parameter is evaluated. If the value of AUDIT_NODE is longer than 7 characters or contains a slash, it is not used and no node name is appended to the log file name. If the value of AUDIT_NODE is valid, it is appended to the log file name.

If the value of AUDIT_LOGFULL is SWITCH, the AUDIT_PGM parameter is evaluated. If the value of AUDIT_PGM is valid, it is used as the absolute pathname of a program to execute when a log switch occurs. The AUDIT_DEFPATH and AUDIT_NODE parameters are also evaluated, and their values used for the alternate log file name and alternate node name.

The auditlog command may be used to override all but the AUDIT_LOGERR parameter.

When auditon is invoked, it initializes the audit event log file. If auditon is invoked when the maximum number of audit files already exist, an error message is displayed (see ``Diagnostics''). In such cases, editing /etc/default/audit to change the AUDIT_DEFPATH parameter controlling which directory log files will be placed may be helpful.

If the event log file cannot be accessed an error message is displayed (see ``Diagnostics''). When the auditon command completes successfully, the following message is displayed:

   Auditing enabled filename

In this case, filename is the name of the audit log file.

The auditon command invokes the auditmap command to create the audit map files.

Auditing remains enabled while the system is running until the auditoff command is executed, or the log full condition of DISABLE or SHUTDOWN occurs, or an audit error is encountered.
