Glossary M MIB Management Information Base. A directory listing information used and maintained by a network's management protocol, such as SNMP. N name server Network Time Protocol NTP A name server is a computer server that implements a name-service protocol. It will normally map a computer-usable identifier of a host to a human-usable identifier for that host. For example, a DNS server might translate the domain name en.wikipedia.org to the IP address 145.97.39.155. See NTP. Network Time Protocol. A protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. NTP uses User Datagram Protocol (UDP) port 123 as its transport layer. NTP is designed particularly to resist the effects of variable latency (jitter). NTP is one of the oldest Internet protocols still in use (since before 1985). NTP was originally designed by Dave Mills of the University of Delaware, who still maintains it, along with a team of volunteers. NTP is not related to the much simpler DAYTIME (RFC 867) and TIME (RFC 868) protocols. P port In IP terminology, an upper-layer process that receives information from lower layers. Each numbered port associates with a specific process. For example, SMTP associates with port 25. S Secure Shell server Simple Network Management Protocol See SSH. An application or device that performs services for connected clients as part of a client-server architecture. A server application, as defined by RFC 2616 (HTTP/1.1), is "an application program that accepts connections in order to service requests by sending back responses." Server computers are devices designed to run such an application or applications, often for extended periods of time, with minimal human direction. Examples of servers include web servers, e-mail servers, and file servers. See also client. See SNMP. OL-18996-01 CLI Reference Guide for the Cisco Secure Access Control System 5.1 GL-3
