NAME
devassign — device assignment database file for a trusted system
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 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 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 formats treated as ptys by login are:
- ptym/*
- pts/*
- pty/*
- pty[x][y]
where
x
is a letter, and
y
is a hex number
- tty[x][y]
where
x
is a letter, and
y
is a hex number
- telnet/*
HP-UX 11i Version 3 is the last release to support
trusted systems functionality.
