Point-to-Point Tunneling Protocol (PPTP)

A network protocol for linking remote locations over the Internet rather than over costly long-distance or leased lines. To accomplish this, PPTP encapsulates other network protocols (such as TCP/IP, IPX, and NetBEUI) and uses encryption to secure the data sent over the Internet. PPTP was developed jointly by Microsoft and U.S. Robotics (3Com).

Policy

A set of rules that governs how remote users log onto the corporate network. Corporate policies are defined by the network administrator and maintained on the Aurorean Policy Server. Policies fall into two general

categories: Internet access and user/group administration. For Internet access, the network administrator determines which ISPs and telephone carriers the remote user can select, what rates are acceptable for phone calls and Internet connection periods, and which regions of the country the remote

user may connect from. These policies are reflected in the customized TollSaver database that is distributed as part of the Aurorean Client. For

user/group administration, the network administrator establishes the log in methods for both ISP access and corporate network access; specifies the use of protocols, encryption, and compression; and determines the user’s right to change his or her username or password.

POP Package

A set of ISPs that can be assigned to one or more client groups. RiverMaster

creates a POP package as the first, most time-consuming step of the Aurorean Client Installation Kit build when the TollSaver database is generated. The

second step of the kit build incorporates configuration values for the system with the POP package and its associated ISPs.

Prescriber

A feature of Enterasys Networks products that diagnoses why a tunnel

connection failed and attempts to correct the problem, either on its own or with user assistance. On Enterasys Networks Aurorean Client, the

Prescriptive Diagnostics Engine performs a step-by-step check of each tunnel connection element, including the COM port or serial driver used, modem or terminal adapter, line to a PBX or the telephone network, local or long
