t. e. The Network Time Protocol ( NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable- latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware .
TCP: Allow traffic to all destinations on ports: 28910, 29900, 29901, 29920, 80, and 443. UDP: Allow all traffic to all destinations. (Necessary for peer-to-peer connections and game play). ... ^ "Ports Used for Call of Duty Games". Activision Support.

MikroTik RouterOS is an operating system based on the Debian GNU/Linux kernel, specifically designed for routers. It is installed on the company's produced networking hardware - RouterBOARD ...
NTP server misuse and abuse covers a number of practices which cause damage or degradation to a Network Time Protocol (NTP) server, ranging from flooding it with traffic (effectively a DDoS attack) or violating the server's access policy or the NTP rules of engagement. One incident was branded NTP vandalism in an open letter from Poul-Henning ...
The Stream Control Transmission Protocol (SCTP) is a computer networking communications protocol in the transport layer of the Internet protocol suite.Originally intended for Signaling System 7 (SS7) message transport in telecommunication, the protocol provides the message-oriented feature of the User Datagram Protocol (UDP), while ensuring reliable, in-sequence transport of messages with ...
A time server is a server computer that reads the actual time from a reference clock and distributes this information to its clients using a computer network. The time server may be a local network time server or an internet time server. The most important and widely used protocol for distributing and synchronising time over the Internet is the ...
SNMP and NTP can also be exploited as reflectors in an amplification attack. An example of an amplified DDoS attack through the Network Time Protocol (NTP) is through a command called monlist, which sends the details of the last 600 hosts that have requested the time from the NTP server back to the requester. A small request to this time server ...
Clock synchronization. Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.
