NTP Enumeration

 

What is NTP?

 

The Network Time Protocol is a protocol for synchronising time across your network, this is especially important when utilising Directory Services.  As SMTP, NTP has been around for 20+ years.  There exists a number of time servers throughout the world that can be used to keep systems synced to each other.

 

NTP utilises UDP port 123 as its primary means of communication.

 

A more detailed explanation and links to associated documentation and RFC's etc. can be found here.

 

Hopefully the tools I have reviewed will go some way to help you enumerate any NTP servers you find.
