Code:

Files Reference
utmp, wtmp, failedlogin File Format
Purpose

Describes formats for user and accounting information.
Description

The utmp file, the wtmp file, and the failedlogin file contain records with user and accounting information.

When a user attempts to logs in, the login program writes entries in two files:

    * The /etc/utmp file, which contains a record of users logged into the system.
    * The /var/adm/wtmp file (if it exists), which contains connect-time accounting records.

On an invalid login attempt, due to an incorrect login name or password, the login program makes an entry in:

    * The /etc/security/failedlogin file, which contains a record of unsuccessful login attempts.

The records in these files follow the utmp format, defined in the utmp.h header file.

utmpset

utmpset(8)						      System Manager's Manual							utmpset(8)

NAME

       utmpset - logout a line from utmp and wtmp file

SYNOPSIS

       utmpset [ -w ] line

DESCRIPTION

       The utmpset program modifies the user accounting database utmp(5) and optionally wtmp(5) to indicate that the user on the terminal line has
       logged out.

       Ordinary init(8) processes handle utmp file records for local login accounting.	The runit(8) program doesn't include code  to  update  the
       utmp file, the getty(8) processes are handled the same as all other services.

       To enable local login accounting, add utmpset to the getty(8) finish scripts, e.g.:

	$ cat /service/getty-5/finish
	#!/bin/sh
	exec utmpset -w tty5
	$

OPTIONS

       -w     wtmp. Additionally to the utmp file, write an empty record for line to the wtmp file.

EXIT CODES

       utmpset returns 111 on error, 1 on wrong usage, 0 in all other cases.
