Domain Time II Server
Version 5.2

Settings on this page control how Domain Time listens and sends traffic to the network.

CAUTION: The default settings on this page are usually correct for most applications. Only make changes if you are sure you need them and you fully understand the effects of the change.

These settings are unique to each machine, and therefore cannot be saved or imported using the Import/Export utilities.

 

 Network Listen 

  Address Family:  

Listen on all IP addresses available
Listen only on these addresses:

 Enter one IP address or hostname per line. You may use any combination of IPv4 and IPv6 addresses. The addresses you enter must exist and be permanently assigned to this machine

Use these settings to tell Domain Time which IP addresses to use when listening for incoming network traffic.

    IMPORTANT: Keep in mind that there can only be one network service listening on any one network port on any one IP address. Domain Time will attempt to control all the enabled time protocol ports on the selected IP address(es) when the service starts.

    You may select which protocols are enabled on the Serve the Time property page.

    DT2: 9909 UDP and TCP (cannot be disabled)
    DT2 over HTTP: 80 TCP (configurable on the Serve the Time property page)
    DT2 Status Monitor: 9911 UDP or TCP (configurable on the Status Reports property page)
    NTP: 123 UDP
    NIST Daytime: 13 UDP and TCP
    TIME/ITP: 37 UDP and TCP

    IPv6 requires operating system support, which is present by default in Vista or above, but must be specifically installed/enabled on XP. Domain Time will function in IPv4-only mode if IPv6 is not present. If both are present, you may choose which to use, or let the system figure it out.

    Domain Time assumes your TCP/IP and Windows networks are configured properly, i.e. name resolution is functioning, rules are in place to permit traffic through switches, routers, and firewalls, any Active Directory/Domain structure is functioning correctly, etc.

 

 Network Send 

DT2:  
NTP:  
TIME/ITP:  
Use blank (or zero) to mean the system should choose a random source port

Use this section to specify a fixed source port for time protocol traffic.

    These settings should be left blank unless you have a specific requirement to send traffic from a specific source port. If you do need to set this port, it is usually best to use the same port that is used for listening (see above).

    Note: Take care in assigning this port to avoid conflicts with any other port that may be used by any other service. In particular, you should not assign a port number in the ranges Windows will use for random source port assignment.
