NetLinx Security

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 DB-9 PROGRAM port on the front panel of the Master).

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.

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.
