• Use the supplied defaults for the data_bits (8), stop_bits (1), and parity (none) parameters.
• To configure the port for EIA flow control, set the control_lines parameter to both and the
input_flow_control and the output_flow_control parameters to eia.
• Set the arap_v42bis parameter to Y.
• Setting the at_guest parameter to Y enables guest access.
• The at_nodeid parameter defines the AppleTalk node address for the remote Apple PowerBook
or Macintosh.
ARA Security
The Model 5390 server provides comprehensive security features that assist you in securing your
Model 5390 servers and the network from unauthorized access. Using these features, you can select
between host-based security (where at least one host on the network is functioning as a security
server) and local password protection (where the passwords are stored on the Model 5390 server).
Optionally, you can use local password protection as a backup to host-based security.
The Model 5390 server provides protection through the use of an administrative password that
controls access to the superuser CLI commands. This password can also protect access to the Model
5390 server through na. The security system provides audit trails that monitor users and their
activities. The Model 5390 server also provides the source code for the Access Control Protocol
(ACP) security system, and the flexibility to integrate Model 5390 security with existing security
for a network-wide system.
The following subsections briefly describe Model 5390 security as it relates to ARA. For a detailed
description of ACP, host-based security, and the acp_userinfo file, see Using Model 5390 Security
starting on page A15-1.
NOTE:
ARA is an 8-bit protocol. If data_bits is set to 7, and parity is
not set to none, the Model 5390 server forces the data_bits setting to 8
and the parity setting to none. Otherwise, the Model 5390 server gener-
ates an error message for the port.
NOTE:
If you are using host-based security, you must define the user
name and password in the acp_userinfo file (see Creating the
acp_userinfo File on page A15-16).
