14 Terminal Security Commands
The terminal commands allow a security administrator to add and manage terminal
definition records. When you add a terminal definition record, the Safeguard software
takes control of the logon dialog at that terminal. When you define a terminal, you can
also specify a particular command interpreter to be started automatically at the terminal
after user authentication. Terminal definitions can be added selectively for some or all
of the terminals on your system.
The automatic starting of specific command interpreter is available only at a Safeguard
terminal. Even though this features can also be specified in a user authentication
record and in a Safeguard configuration record, it is enforced only at terminals
controlled by the Safeguard software.
Previously, an extended logon dialog was available only at Safeguard terminals.
Effective with D30, the TACL command interpreter also provides these extended
features as long as Safeguard is running.
You cannot specify access authorities with the terminal commands. These commands
do not allow you to specify an access control list (ACL). To specify an ACL for a
terminal, you must use DEVICE or SUBDEVICE commands, depending on how
terminals are named on your system.
Except for the INFO TERMINAL command, use of the terminal commands is restricted
to security group members. INFO TERMINAL can be executed by any user. If you
have not defined the SECURITY-ADMINISTRATOR and SYSTEM-OPERATOR
groups, any super-group member can use the terminal commands. (For information
about how to define security groups, see Section 13, Security Group Commands.)
Terminals controlled by the Safeguard software can also be configured for exclusive
access, which insures that any user who is logged on to a Safeguard terminal has
exclusive access to the terminal until the user logs off. For more information, see
TERMINAL-EXCLUSIVE-ACCESS { ON | OFF } on page 16-26.
