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
ISP s 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
