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.
