NTP Servers

The NTP protocol enbles your operating system to automatically set the correct time of day, accurate to within a few milliseconds.

For security reasons, the UCD network is configured to block outgoing connections to external NTP servers. This means that your computer or server may will not be able to automatically update it's time of day to a correct and accurate value.

UCD IT Services therefore provide two internal NTP servers that can be used by client or server machines on the UCD network:

  • ntp0.ucd.ie
  • ntp1.ucd.ie

Your operating system(s) will need to be configured to point to these servers rather than using the operating system defaults. Click below to find instructions for doing this for your operating system:
