AULAST:(8) System Administration Utilities AULAST:(8)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

LAST,LASTB(1) Linux System Administrator's Manual LAST,LASTB(1)NAME
last, lastb - show listing of last logged in users
SYNOPSIS
last [-R] [-num] [ -n num ] [-adiox] [ -f file ] [ -t YYYYMMDDHHMMSS ] [name...] [tty...]
lastb [-R] [-num] [ -n num ] [ -f file ] [ -t YYYYMMDDHHMMSS ] [-adiox] [name...] [tty...]
DESCRIPTION
Last searches back through the file /var/log/wtmp (or the file designated by the -f flag) and displays a list of all users logged in (and
out) since that file was created. Names of users and tty's can be given, in which case last will show only those entries matching the
arguments. Names of ttys can be abbreviated, thus last 0 is the same as last tty0.
When last catches a SIGINT signal (generated by the interrupt key, usually control-C) or a SIGQUIT signal (generated by the quit key, usu-
ally control-), last will show how far it has searched through the file; in the case of the SIGINT signal last will then terminate.
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.
Lastb is the same as last, except that by default it shows a log of the file /var/log/btmp, which contains all the bad login attempts.
OPTIONS -num This is a count telling last how many lines to show.
-n num The same.
-t YYYYMMDDHHMMSS
Display the state of logins as of the specified time. This is useful, e.g., to determine easily who was logged in at a particular
time -- specify that time with -t and look for "still logged in".
-R Suppresses the display of the hostname field.
-a Display the hostname in the last column. Useful in combination with the next flag.
-d For non-local logins, Linux stores not only the host name of the remote host but its IP number as well. This option translates the
IP number back into a hostname.
-i This option is like -d in that it displays the IP number of the remote host, but it displays the IP number in numbers-and-dots nota-
tion.
-o Read an old-type wtmp file (written by linux-libc5 applications).
-x Display the system shutdown entries and run level changes.
NOTES
The files wtmp and btmp might not be found. The system only logs information in these files if they are present. This is a local configura-
tion issue. If you want the files to be used, they can be created with a simple touch(1) command (for example, touch /var/log/wtmp).
FILES
/var/log/wtmp
/var/log/btmp
