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).
iptables
While not accessible via the Web UI,
iptables
(an application allowing for customizable access
restrictions) have been supported since NetClock Software Version 5.4.1.
Note that
iptables
is always ON, and its policies can only be accessed via the Command Line
Interface (see "CLI Commands" on page 382) in combination with the
Sudo
command. Please
also note that you need to have admin user rights to run this command.
Note:
A listing of recommended and default network settings can be found under
"Default and Recommended Configurations" on page 319
.
