of the Internet Engineering Task Force (IETF). PPP is

 

commonly used when remote computers call an Internet

 

service provider (ISP) or a corporate server that is configured

 

to receive incoming calls.

Profile

Usage setup of the ACS either as a Console Access Server

 

(CAS), a Terminal Server, or a Remote Access Server.

Proxy ARP

The technique in which one machine, usually a router,

 

answers ARP (Address Resolution Protocol) requests

 

intended for another machine. By "faking" its identity, the

 

router accepts responsibility for routing packets to the "real"

 

destination. Proxy ARP allows a site to use a single IP

 

address with two physical networks. Subnetting would

 

normally be a better solution.

RADIUS

Remote Authentication Dial-In User Service is a client/server

 

protocol and software that enables remote access servers to

 

communicate with a central server to authenticate dial-in

 

users and authorize their access to the requested system or

 

service. RADIUS allows a company to maintain user profiles

 

in a central database that all remote servers can share.

Root Access

Root is the term for a very highly privileged administrative

 

user (particularly in unix environments). When an ISP grants

 

you root access, it means you will have full control of the

 

server. With full control, you will be able to install any

 

software and access any file on that server.

Routing Table

The Routing Table defines which interface should transmit an

 

IP packet based on destination IP information.

Secure Shell (SSH)

SSH has the same functionality as Telnet (see definition for

 

Telnet), but adds security by encrypting data before sending

 

it through the network.

Server Farm

A collection of servers running in the same location (see

 

Cluster).
