auditd Daemon

The following list summarizes the tasks of the auditd daemon:

The auditd daemon can be started automatically when the system is booted into multiuser mode. Or, you can start the daemon from the command line. When the auditd daemon is started, it calculates the amount of free space that is necessary for audit files.

The auditd daemon uses the list of audit directories in the audit_control file as possible locations for creating audit files. The daemon maintains a pointer into this list of directories, starting with the first directory. Every time the auditd daemon needs to create an audit file, the daemon puts the file into the first available directory in the list. The list starts at the auditd daemon's current pointer. You can reset the pointer to the beginning of the list by running the audit -s command. The audit -n command instructs the daemon to switch to a new audit file. The new file is created in the same directory as the current file.
