APPENDIX E: Terminology TERM Gateway Hub Internet Intranet IPMI Key lifetimes LAN LDAP LED MAC address MSCHAP NAT Net mask NFS NTP OUT OF BAND PAP PPP RADIUS MEANING 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 that 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. Local Area Network. 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. Light-Emitting Diode. 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 devices. The MAC address is used by the local Internet router in order to direct console server traffic to it rather than someone 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. Network File System is a protocol that allows file sharing across a network. Users can view, store, and update files on a remote computer. Network Time Protocol (NTP) used to synchronize clock times in a network of computers. Out-of-Band (OOB) management is any management done over channels and interfaces that are separate from those used for user/customer data. Examples include a serial console interface or a network interface connected to a dedicated management network that is not used to carry customer traffic, or to a BMC/service processor. Any management done over the same channels and interfaces used for user/customer data is In Band. Password Authentication Protocol (PAP) is the usual method of user authentication used on the internet: sending a username and password to a server where they are compared with a table of authorized users. Whilst most common, PAP is the least secure of the authentication options. Point-to-Point Protocol. A networking protocol for establishing simple links between two peers. The Remote Authentication Dial-In User Service (RADIUS) protocol was developed by Livingston Enterprises as an access server authentication and accounting protocol. The RADIUS server can support a variety of methods to authenticate a user. When it is provided with the username and original password given by the user, it can support PPP, PAP or CHAP, UNIX login, and other authentication mechanisms. 281
