NAME
ttys - terminal control database file for trusted systems
SYNOPSIS
DESCRIPTION
The system supports a single terminal control database containing entries for each local terminal that can log into the system. Authentica-
tion programs use information contained in the terminal control database to determine if login from the terminal is permitted. Additional
fields are maintained for informational purposes.
The format of the terminal control database file is identical to other system authentication database files. For more information on the
file format, see authcap(4). The file consists of keyword field identifiers and values for those fields. The keyword identifiers supported
and their use include:
This field defines the terminal device name for the entry. The terminal device
is expected to be contained in the directory, therefore this prefix should not be specified. If the terminal entry
describes the device, the field should contain
This field records the user id of the last user to successfully login using
the terminal device.
This field records the last successful login time to the terminal device.
This field records the last unsuccessful login time to the terminal device.
This field records the number of consecutive unsuccessful login attempts to
the terminal device.
This field specifies the maximum number of consecutive unsuccessful login
attempts permitted using the terminal before the terminal is locked. Once the terminal is locked, it must be unlocked by
an authorized administrator.
This field specifies the login timeout value (sec).
This field specifies the delay between login tries (sec).
This flag field indicates whether the terminal device has been administratively
locked or not. This field is manipulated by authorized administrators only.
EXAMPLES
The following is an example of a terminal control database entry:
