User Summary
Gets the time and configuration variables from an NTP server. We send two
requests: a time request and a "read variables" (opcode 2) control message.
Without verbosity, the script shows the time and the value of the
version, processor, system,
refid, and stratum variables. With verbosity, all
variables are shown.
See RFC 1035 and the Network Time Protocol Version 4 Reference and Implementation Guide (http://www.eecis.udel.edu/~mills/database/reports/ntp4/ntp4.pdf) for documentation of the protocol.
Example Usage
nmap -sV -sC <target>
