Domain Name System that allocates Internet domain names and translates them into IP addresses. A domain name is
a meaningful and easy to remember name for an IP address.
The technique for converting a readable message (plaintext) into apparently random material (ciphertext) which cannot
be read if intercepted. The proper decryption key is required to read the message.
A physical layer protocol based upon IEEE standards
A network gateway device that protects a private network from users on other networks. A firewall is usually installed to
allow users on an intranet access to the public Internet without allowing public Internet users access to the intranet.
A machine that provides a route (or pathway) to the outside world.
A network device that allows more than one computer to be connected as a LAN, usually using UTP cabling.
A worldwide system of computer networks - a public, cooperative, and self-sustaining network of networks accessible to
hundreds of millions of people worldwide. The Internet is technically distinguished because it uses the TCP/IP set of
protocols.
A private TCP/IP network within an enterprise.
Intelligent Platform Management Interface (IPMI) is a set of common interfaces to a computer system which system
administrators can use to monitor system health and manage the system. The IPMI standard defines the protocols for
interfacing with a service processor embedded into a server platform.
The length of time before keys are renegotiated
The Lightweight Directory Access Protocol (LDAP) is based on the X.500 standard, but significantly simpler and more
readily adapted to meet custom needs. The core LDAP specifications are all defined in RFCs. LDAP is a protocol used
to access information stored in an LDAP server.
Every piece of Ethernet hardware has a unique number assigned to it called its MAC address. Ethernet is used locally
to connect the console server to the Internet, and it may share the local network with many other appliances. The MAC
address is used by the local Internet router in order to direct console server traffic to it rather than somebody else in the
local area. It is a 48-bit number usually written as a series of 6 hexadecimal octets, e.g. 00:d0:cf:00:5b:da. A console
server has a MAC address listed on a label underneath the device.
Microsoft Challenge Handshake Authentication Protocol (MSCHAP) is authentication for PPP connections between a
computer using a Microsoft Windows operating system and a network access server. It is more secure than PAP or
CHAP, and is the only option that also supports data encryption.
Network Address Translation. The translation of an IP address used on one network to an IP address on another
network. Masquerading is one particular form of NAT.
The way that computers know which part of a TCP/IP address refers to the network, and which part refers to the host
range.
