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: 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 unsuccessful login attempt. WARNINGS
Remote terminals (ptys) should not be added to the or databases. 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, and y is a hex number HP-UX 11i Version 3 is the last release to support trusted systems functionality. AUTHOR

ttys - Terminal control database file (Enhanced Security) DESCRIPTION
Notes The secure terminal database file, /etc/securettys, controls root logins for all security levels. The file is described in the securet- tys(4) reference page. By default, the enhanced security terminal control information is stored in database format (ttys.db). The information was formerly stored in the ttys file and is converted to database format in an update installation. The convauth utility converts an existing ttys file to database format. The enhanced security terminal control database (ttys.db) contains an entry for each terminal or X displayname that can be used for logging in. It supports wildcarding of the entire terminal name or displayname only. Authentication programs use information in the terminal con- trol database to determine if a login is permitted on the specified terminal. Information from the device assignment database (/etc/auth/system/devassign) can also affect terminal login permissions. Successful and unsuccessful login attempts on the terminal are optionally recorded in the terminal control database, and the information can be used to disable terminal logins when breakin attempts are suspected. The /usr/tcb/bin/dxdevices GUI provides a way to create terminal control database entries and to alter the system default values for the fields. The edauth utility can also be used to display and modify terminal control database entries. A terminal control database entry consists of keyword field identifiers and values for those fields. If a necessary value is not specified in an entry, a default value for the field is supplied from the system default file (/etc/auth/system/default). For more information on the field format, see the authcap(4) reference page. The following keyword field identifiers are supported: This field defines the terminal device name for the entry. The system expects that terminal devices are in the /dev directory and therefore this prefix should not be specified. If the terminal entry describes the /dev/tty1 device, the t_devname field should contain tty1. This field is ignored if it is set in a template or in the default database. This field contains the user ID of the last user who successfully logged in using the terminal device. This field is ignored if it is set in a tem- plate or in the default database. This field is a time_t value that records the last successful login time to the terminal device. This field is ignored if it is set in a template or in the default database. This field contains the user ID of the last user who unsuccess- fully attempted to log in using the terminal device. This field is ignored if it is set in a template or in the default database. This field is a time_t value that records the last unsuccessful login time to the terminal device. This field is ignored if it is set in a tem- plate or in the default database. This field contains the user ID of the user who successfully logged in before the user identified in the t_uid field. This represents the UID of the previous login session. This field is ignored if it is set in a template or in the default database. This field is a time_t value that contains the system time of last logout associated with this terminal device. This value marks the end of the previous login session associated with the user identified by t_prevuid. This field records the number of consecutive unsuccessful login attempts to the terminal device. This field is ignored if it is set in a template or in the default database. 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 is a time_t value that identifies the login delay enforced by authentication programs between unsuccessful login attempts. This field is designed to slow the rate at which penetration attempts on a terminal device can occur. This field indicates whether the terminal device has been administratively locked. This field is manipulated by authorized administrators only. This field specifies the time interval in seconds after t_unsuctime to wait before ignoring t_failures. Zero means never ignore t_failures. This field specifies the login time-out value in seconds. If a login attempt is initiated by entering a user name at the login prompt but successful authentication is not completed within the time-out interval specified, the login attempt is aborted. This field indicates that the entry is an X window display managed by rather than a terminal device. This field is ignored if it is set in a template or in the default database. EXAMPLES
The following example shows a typical terminal control database entry: console:t_devname=console: :t_uid=jdoe:t_logtime#675430072: :t_unsucuid=jdoe:t_unsuctime#673610809: :t_prevuid=root:t_prevtime#671376915: :chkent: This entry is for the system console device, /dev/console. The most recent successful login session was for the user jdoe. The most recent unsuccessful login attempt was also by user jdoe. Before the most recent successful login session, the root account was used to log in to the console. The entry records the system time for the current successful login, the end of the previous successful login session, and the time of the most recent unsuccessful login attempt. FILES
