NXC-ME260 NetLinx Master-Ethernet Card/Module

NetLinx Security

NetLinx Masters (version 2.10.80 or later) 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 DB9

PROGRAM port on the rear of the Controller).

NetLinx Security Features

NetLinx security allows you to define access rights for users or groups.

The following table lists the NetLinx features that the administrator (or other 'qualified' user) may

grant or deny access to.

Security Terms Used in This Document

User

A user is a single potential client of the NetLinx Master.

Group

A group is a logical collection of users. Note that any properties possessed by groups (i.e., access

rights, directory associations, etc.) are inherited by all of the members of the group.

Always use the Program port when entering potentially sensitive security information. The Telnet

server interface exposes this security information to the network in clear text format, which would

be rather easy to intercept by an unauthorized client. By using the Program port, there is some

level of security during the configuration of the database, due to the physical proximity of the user

to the system.

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.

NetLinx Security Features

NetLinx Master Security Configuration The user has access to the security configuration commands of the

Master. Only those users with security configuration access rights

granted will have access to the security configuration

commands.

Telnet Security The user has access to the Telnet server functionality. All basic

commands are available to the user.

Terminal (PROGRAM port) Security The user has access to the Terminal (RS232 PROGRAM port) server

functionality. All basic commands are available to the user.

HTTP (web server) Security The user has access to the HTTP server functionality. Directory

associations assign specific directories/files to a particular user.

FTP Security The user has access to the FTP server functionality. Only the adminis-

trator account has access to the root directory; all other 'qualified' cli-

ents are restricted to the /user/ directory and its 'tree'.
