AUDIT_WARN(8) Maintenance Commands and Procedures AUDIT_WARN(8)

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(8) 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(5). 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.


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(7)) due to configuration errors. The
name string is -- to indicate that no plugin name
applies.


retry
The plugin name reports it has encountered a
temporary failure.


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.


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 there was a problem creating a symlink from
/var/run/.audit.log to the current audit log file.

NOTES

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.
