NetLinx Security with a Terminal Connection

NetLinx ME260 Masters (build 139) have built-in security capabilities. It will require a valid user
name and password to access the NetLinx System's Telnet, HTTP and FTP servers.
The security capabilities are configured and applied via a Telnet connection or the NetLinx
Master's RS-232 terminal interface (the RS232 Program port).
Always use the RS232 Program port when entering potentially sensitive security information. The
Telnet server interface exposes this security information to the network in clear text format, which
could be intercepted by an unauthorized network client. By using the RS232 Program port, there is
security during the configuration of the database due to the physical proximity of the user to the
system.

NetLinx Security Features

NetLinx security allows you to define access rights for users or groups.
A "User" represents a single potential client of the NetLinx Master, while a "Group" represents a
logical collection of users. Any properties possessed by groups (i.e., access rights, directory
associations, etc.) are inherited by all the members of the group.
The following table lists the NetLinx features that the administrator (or other 'qualified' user) may
grant or deny access to.

Initial Setup via a Terminal Connection

Security administration and configuration is done via a Terminal communication through the
RS232 Program port on the NetLinx Master.

Establishing a Terminal connection

1. Launch the HyperTerminal application from its' default location (Start > Programs >
Accessories > Communications).
2. Apply power to the NetLinx Master and allow it to boot up.
3. Connect the PC COM (RS232) port to the RS232 Program port on the NetLinx Master. Note
the baud rate settings for the Master.
