NAME

devassign − device assignment database file for a trusted system

SYNOPSIS

/tcb/files/devassign

DESCRIPTION

The system supports a single device assignment database that contains entries for local and remote login terminals.

The format of the terminal control database file is identical to other trusted 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:

v_devs This field specifies a comma separated list of aliases that refer to the same device defined by the entry. Use of this field avoids the need to replicate device assignment database entries for all device aliases.

v_type This field specifies the device that is described by the entry. Device types supported include:

terminal The device is assigned as a local or remote login terminal device.

v_users This field, if specified, contains a comma separated list of user names that are permitted to use the device for login or the import/export of data. If the list is not present, all users are permitted to use the device. If the list is present, it is searched for a match by the login program to determine if the user is permitted to use the device.

EXAMPLES

The following is an example of a device assignment database entry for a terminal device assigned as a login device:

tty0:v_devs=/dev/tty0:\
:v_type=terminal:\
:chkent:
