Group and User Security Access Options (Cont.)
Option Description
Telnet Access: If selected, a valid username and password is required for Telnet Access. Telnet
access allows communication over either the Telnet and/or SSH Ports.
Note: SSH version 2 (only) is supported.
• To establish a secure Telnet connection, an administrator can decide to disable
the Telnet Port and then enable the SSH Port. Refer to the Manage System -
Server Options section on page 51.
Configuration: If selected, a valid username and password is required before allowing a group/
user to alter the current Master’s security and communication settings via
NetLinx Studio.
This includes such things as: IP configuration/Reset, URL list settings, Master
communication settings, and security parameters.
ICSP Connectivity: If selected, a valid username and password is required to communicate with the
NetLinx Master via an ICSP connection (TCP/IP, UDP/IP, and RS-232).
• This feature allows communication amongst various AMX hardware and
software components. This feature works in tandem with the Require
Encryption option (see below) to require that any application or hardware
communicating with the Master must provide a valid username and password.
• In a Master-to-Master system, the Master which accepts the IP connection
initiates the authentication process. This configuration provides compatibility
with existing implementations and provides more flexibility for the
implementation of other devices.
Note: The ICSP Connectivity option is required to allow authenticated and/or
secure communication between the Master and other AMX hardware/software.
To establish an authenticated ICSP connection (where the external AMX hard-
ware/software has to provide a valid username and password), this option must
be enabled.
Encrypt ICSP Connection: If selected, this option requires that any data being transmitted or received via an
ICSP connection (among the various AMX products) be encrypted, and that any
application or hardware communicating with the Master over ICSP must provide
a valid username and password.
Note: When enabled, this option requires more processor cycles to maintain.
