Access Rules - Spectracom VersaSync User Manual

2.7 Configuring Network Settings
The Network Services panel has ON/OFF toggle switches for the following daemons and fea-
tures:
Daytime Protocol, RFC-867 : A standard Internet service, featuring an ASCII daytime rep-
resentation, often used for diagnostic purposes.
Time Protocol, RFC-868 : This protocol is used to provide a machine-readable, site-inde-
pendent date and time.
Telnet : Remote configuration
FTP server: Access to logs
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 inspecting tcp
packets. Default = ON.
If not needed, or wanted (out of concern for potential security risks), tcpdump can be dis-
abled 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 can-
not be enabled again (even after a software upgrade).
