NetLinx Security Terms
The following table lists those commonly used NetLinx Security terms:
When using Mozilla on a Linux machine, the Group Rights column checkboxes (from
within the Modify User page) can become greyed-out but are actually present.
Installation of this new SSL functionality onto your Master will cause security
setup via Telnet to be disabled. Although Telnet security configuration access can
no longer be used with the Master, a Terminal connection (using HyperTerminal) can
still be established using the Master’s RS232 Program port. Refer to the NetLinx
Security with a Terminal Connection section on page 93 for detailed Terminal security
setup procedures.
NetLinx Security Terms
User A user is a single potential client of the NetLinx Master.
Administrator An administrator has privileges to modify existing NetLinx Master access
groups, users, and their rights. The administrator can also assign NetLinx
communication access rights for different users or groups (ex: Telnet and
HTTP access) and configure the SSL server certificate.
Group A group is a logical collection of users. Note that any properties possessed by
groups (ex: access rights, directory associations, etc.) are inherited by all of the
members of the group.
User name A user name is a valid character string (4 - 20 alpha-numeric characters)
defining the user. This string is case sensitive. Each user name must be
unique.
Group name A group name is a valid character string (4 - 20 alpha-numeric characters)
defining the group. This string is case sensitive. Each group name must be
unique.
Password A password is a valid character string (4 - 20 alpha-numeric characters) to
supplement the user name in defining the potential client. This string is also
case sensitive.
Access Rights Each of the NetLinx Master features has security procedures defined for them.
The access right for a particular feature determines if the user or group will
have access to the feature.
