2.9.3 Network Services
Several standard network services can be enabled or disabled via the easily accessible Net-
work Services Panel under MANAGEMENT > Network Setup :
The Network Services panel has ON/OFF toggle switches for the following daemons and
features:
SSH : Secure Shell cryptographic network protocol for secure data communication
HTTP : Hypertext Transfer Protocol
tcpdump : A LINUX program that can be used to monitor network traffic by inspect-
ing tcp packets. Default = ON.
If not needed, or wanted (out of concern for potential security risks),
tcpdump can
be disabled permanently: Once toggled to OFF, and after executing a page reload,
tcpdump will be deleted from the system: The toggle switch will be removed, and
the function cannot be enabled again (even after a software upgrade).
2.9.4 Access Rules
Network access rules restrict access to only those assigned networks or nodes defined. If
no access rules are defined, access will be granted to all networks and nodes.
Note: In order to configure Access Rules, you need
ADMINISTRATOR rights.
To configure a new, or delete an existing access rule:
1.
Navigate to the MANAGEMENT > Network Setup screen.
2.
In the Actions panel on the left, click on Access Control.
