NetLinx Security - Web Server
System Level Security Page (Cont.)
Feature Description
Terminal (RS232) Access: This selection determines if a username and password is
required for Terminal communication (through the RS232
Program port).
• If Terminal Security is enabled, a user must have sufficient
access rights to login to a Terminal session and communicate
with the Master.
HTTP Access: This selection determines if a username and password is
required for communication over HTTP or HTTPS Ports (see
FIG. 50).
• If enabled, a user must have sufficient access rights to browse
to the NetLinx Master via a Web Browser.
• Enabling this field requires the user (within a new session)
submit a valid username and password before being able
to view the web server pages.
• If disabled, the Master is open for viewing and does not ask
for this information during any consecutive sessions
(until the user attempts to access a feature which is
enabled within this page).
• This requirement of a valid username and password affects
both HTTP and HTTPS communication with the target
Master using the web server.
Telnet Access: This selection determines if a username and password is
required for Telnet Access (see FIG. 50).
• If Telnet access is enabled, a username and password is
required before allowing communication over either the Telnet
and/or SSH Ports. SSH version 2 is only supported.
• This authorized user must have sufficient access rights to login
through a Telnet session to the Master.
• To establish a secure Telnet connection, an administrator can
decide to disable the Telnet Port and then enable the SSH
Port. Refer to the Setting the Master’s Port
Configurations section on page 94.
Configuration (security): This selection determines if a username and password is
required before allowing a group/user to alter the current Master’s
security configuration and communication settings (see FIG. 50).
• Configuration access provides the user with the ability to
perform configuration functions on the NetLinx system through
NetLinx Studio. This includes such things as: IP
configuration/Reset, URL list settings, Master
communication settings, and security parameters.
• If security Configuration is enabled, a user/group must have
sufficient access rights to access the Main Security Menu.
• Any time a configuration operation is performed, the Master
verifies the current access rights for that feature and then
requires a valid username and password
(if not already logged in).
- An example would be if you are trying to add a New User or
modify the rights of an existing Group.
