Network Services

Several standard network services can be enabled or disabled via the easily accessible Network Services Panel under MANAGEMENT > Network Setup:

The Network Services panel has ON/OFF toggle switches for the following daemons and features:

• System Time Message: A once-per second Time Message sent out via Multicast; for details, see System Time Message.
• Daytime Protocol, RFC-867: A standard Internet service, featuring an ASCII daytime representation, often used for diagnostic purposes.
• Time Protocol, RFC-868: This protocol is used to provide a machine-readable, site-independent date and time.
• Telnet: Remote configuration
• SSH + SFTP: Secure Shell cryptographic network protocol for secure data communication and secure access to logs.
• HTTP: Hypertext Transfer Protocol. Default = OFF.
• tcpdump: A LINUX program that can be used to monitor network traffic by inspecting tcp packets. Default = ON.
  If not needed, or wanted (out of concern for potential security risks), tcpdump can be disabled permanently: Once Remove is selected, tcpdump will be deleted from the system: the Web UI section will be removed, and the function cannot be enabled again (even after a software upgrade) unless a full CLEAN upgrade is performed. Removing tcpdump on this page will also remove the PTP-specific functionality (see The PTP TCP Dump Collection Panel).
