NAME

       aulast - a program similar to last

SYNOPSIS

       aulast [ options ] [ user ] [ tty ]

DESCRIPTION

       aulast  is  a  program  that prints out a listing of the last logged in users similarly to the program last and lastb. Aulast searches back
       through the audit logs or the given audit log file and displays a list of all users logged in (and out) based on the range of time  in  the
       audit  logs. Names of users and tty's can be given, in which case aulast will show only those entries matching the arguments. Names of ttys
       can be abbreviated, thus aulast 0 is the same as last tty0.

       The pseudo user reboot logs in each time the system is rebooted. Thus last reboot will show a log of all reboots since  the  log  file  was
       created.

       The  main  difference  that  a user will notice is that aulast print events from oldest to newest, while last prints records from newest to
       oldest. Also, the audit system is not notified each time a tty or pty is allocated, so you may not see quite  as  many  records	indicating
       users and their tty's.

OPTIONS

       --bad  Report on the bad logins.

       --extract
	      Write raw audit records used to create the displayed report into a file aulast.log in the current working directory.

       -ffile Use the file instead of the audit logs for input.

       --proof
	      Print  out the audit event serial numbers used to determine the preceding line of the report. A Serial number of 0 is a place holder
	      and not an actual event serial number. The serial numbers can be used to examine the actual audit records in more  detail.  Also	an
	      ausearch query is printed that will let you find the audit records associated with that session.

       --stdin
	      Take audit records from stdin.

EXAMPLES

       To see this month's logins
       ausearch --start this-month --raw | aulast --stdin

NAME

       auditd - The Linux Audit daemon

SYNOPSIS

       auditd [-f] [-l] [-n] [-s disable|enable|nochange]

DESCRIPTION

       auditd is the userspace component to the Linux Auditing System. It's responsible for writing audit records to the disk. Viewing the logs is
       done with the ausearch or aureport utilities. Configuring the audit rules is done with the auditctl utility. During startup, the  rules	in
       /etc/audit/audit.rules  are  read  by auditctl and loaded into the kernel. Alterately, there is also an augenrules program that reads rules
       located in /etc/audit/rules.d/ and compiles them into an audit.rules file. The audit daemon itself has some configuration options that  the
       admin may wish to customize. They are found in the auditd.conf file.

OPTIONS

       -f     leave the audit daemon in the foreground for debugging. Messages also go to stderr rather than the audit log.

       -l     allow the audit daemon to follow symlinks for config files.

       -n     no fork. This is useful for running off of inittab or systemd.

       -s=ENABLE_STATE
	      specify when starting if auditd should change the current value for the kernel enabled flag. Valid values for ENABLE_STATE are "dis-
	      able", "enable" or "nochange". The default is to enable (and disable when auditd terminates). The value of the enabled flag  may	be
	      changed during the lifetime of auditd using 'auditctl -e'.

SIGNALS

       SIGHUP causes auditd to reconfigure. This means that auditd re-reads the configuration file. If there are no syntax errors, it will proceed
	      to implement the requested changes. If the reconfigure is successful, a DAEMON_CONFIG event is recorded in the logs. If not success-
	      ful,  error handling is controlled by space_left_action, admin_space_left_action, disk_full_action, and disk_error_action parameters
	      in auditd.conf.

       SIGTERM
	      caused auditd to discontinue processing audit events, write a shutdown audit event, and exit.

       SIGUSR1
	      causes auditd to immediately rotate the logs. It will consult the max_log_size_action to see if it should keep the logs or not.

       SIGUSR2
	      causes auditd to attempt to resume logging. This is usually needed after logging has been suspended.

FILES

       /etc/audit/auditd.conf - configuration file for audit daemon

       /etc/audit/audit.rules - audit rules to be loaded at startup

       /etc/audit/rules.d/ - directory holding individual sets of rules to be compiled into one file by augenrules.

NOTES

       A boot param of audit=1 should be added to ensure that all processes that run before the audit daemon starts is marked as auditable by  the
       kernel. Not doing that will make a few processes impossible to properly audit.

       The  audit  daemon  can	receive audit events from other audit daemons via the audisp-remote audispd plugin. The audit daemon may be linked
       with tcp_wrappers to control which machines can connect. If this is the case, you can add an entry to hosts.allow and deny.
