Name

audit_warn– audit daemon warning script

Synopsis

/etc/security/audit_warn [option [arguments]]

Description

The audit_warn utility processes warning or error messages from the audit daemon. When a problem is encountered, the audit daemon, auditd ### UNMATCHED MARKUP: manvolnum ### calls audit_warn with the appropriate arguments. The option argument specifies the error type.

The system administrator can specify a list of mail recipients to be notified when an audit_warn situation arises by defining a mail alias called audit_warn in aliases(4). The users that make up the audit_warn alias are typically the audit and root users.

Options

The following options are supported:

allhard count

Indicates that the hard limit for all filesystems has been exceeded count times. The default action for this option is to send mail to the audit_warn alias only if the count is 1, and to write a message to the machine console every time. It is recommended that mail not be sent every time as this could result in a the saturation of the file system that contains the mail spool directory.

allsoft

Indicates that the soft limit for all filesystems has been exceeded. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

auditoff

Indicates that someone other than the audit daemon changed the system audit state to something other than AUC_AUDITING. The audit daemon will have exited in this case. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

ebusy

Indicates that the audit daemon is already running. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

getacdir count

Indicates that there is a problem getting the directory list or plugin list from audit_control(4). The audit daemon will hang in a sleep loop until the file is fixed. The default action for this option is to send mail to the audit_warn alias only if count is 1, and to write a message to the machine console every time. It is recommended that mail not be sent every time as this could result in a the saturation of the file system that contains the mail spool directory.

hard filename

Indicates that the hard limit for the file has been exceeded. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

nostart

Indicates that auditing could not be started. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console. Some administrators may prefer to modify audit_warn to reboot the system when this error occurs.

plugin name error count text

Indicates that an error occurred during execution of the auditd plugin name. The default action for this option is to send mail to the audit_warn alias only if count is 1, and to write a message to the machine console every time. (Separate counts are kept for each error type.) It is recommended that mail not be sent every time as this could result in the saturation of the file system that contains the mail spool directory. The text field provides the detailed error message passed from the plugin. The error field is one of the following strings:

load_error

Unable to load the plugin name.

sys_error

The plugin name is not executing due to a system error such as a lack of resources.

config_error

No plugins loaded (including the binary file plugin, audit_binfile(5)) due to configuration errors in audit_control(4). The name string is -- to indicate that no plugin name applies.

retry

The plugin name reports it has encountered a temporary failure. For example, the audit_binfree.so plugin uses retry to indicate that all directories are full.

no_memory

The plugin name reports a failure due to lack of memory.

invalid

The plugin name reports it received an invalid input.

failure

The plugin name has reported an error as described in text.

postsigterm

Indicates that an error occurred during the orderly shutdown of the audit daemon. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

soft filename

Indicates that the soft limit for filename has been exceeded. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

tmpfile

Indicates that the temporary audit file already exists indicating a fatal error. The default action for this option is to send mail to the audit_warn alias and to write a message to the machine console.

Notes

This functionality is available only if the Solaris Auditing feature has been enabled. See bsmconv ### UNMATCHED MARKUP: manvolnum ### for more information.

If the audit policy perzone is set, the /etc/security/audit_warn script for the local zone is used for notifications from the local zone's instance of auditd. If the perzone policy is not set, all auditd errors are generated by the global zone's copy of /etc/security/audit_warn.
