ttys(4)ttys(4)NAMEttys - terminal control database file for trusted systems
SYNOPSISDESCRIPTION
The system supports a single terminal control database containing
entries for each local terminal that can log into the system. Authenti‐
cation programs use information contained in the terminal control data‐
base 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 specifies the maximum number of consecutive unsuccessful
login
attempts permitted using the terminal before the ter‐
minal 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 adminis‐
tratively
locked or not. This field is manipulated by autho‐
rized administrators only.
