Figure 34-37. Configuration > Inbound Proxy page NTP tab
The Proxy NTP Servers section is used to create the list of Ranger Gateway/NTP Servers pairs
to process NTP requests from ZoneRanger managed devices. In the case of multiple entries in
the list, ZoneRanger will continue to use a Ranger Gateway/NTP Server pair that successfully
responds to NTP requests. If a Ranger Gateway/NTP Server fails to respond, another entry in
the list is chosen.
This Configuration > Proxy page NTP tab will be disabled if the ZoneRanger has been
configured to act as an NTP server on the Configuration > System page Time tab using the
ZoneRanger Acts As NTP Server checkbox.
The NTP Proxy Logging levels are:
Log Level
None
Short
Full
This NTP Proxy log can be downloaded by the downloadFile command on a Ranger
Gateway. The log file is called /log/ntpProxy.log . The log file may also be viewed on
the View > Service Logs page.
If Validate Authentication is checked, all NTP proxy requests are first validated to ensure that
they match one of the listed keys. This is useful to eliminate spurious NTP requests from
unsecure devices. The Keys section is used to create the list of specific NTP keys ZoneRanger
can use to authenticate the incoming NTP request.
