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 login terminals.
The format of the terminal control database file is identical to other trusted system authentication data-
base 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 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:
WARNINGS
Remote terminals (ptys) should not be added to the devassign or ttys databases. Device name for-
mats treated as ptys by login are:
ptym/*
pts/*
pty/*
pty[x][y]wherex is a letter, and y is a hex number
tty[x][y]wherex is a letter, and y is a hex number
telnet/*
HP-UX 11i Version 3 is the last release to support trusted systems functionality.
