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. 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 defines the terminal device name for the entry. The terminal
       device
			 is expected to be contained in the directory,	there‐
			 fore this prefix should not be specified. If the ter‐
			 minal 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 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.

EXAMPLES
       The following is an example of a terminal control database entry:

       This entry is for the system console device, The most recent successful
       login  session  was  for the user The entry records the system time for
       the current successful login and the time of the most recent unsuccess‐
       ful login attempt.

WARNINGS

       Device name formats treated as ptys by login are:

	      where	  x   is   a
			  letter,
			  and y is a
			  hex number
	      where	  x   is   a
			  letter,
