Share modems among machines
Does everyone in your company want a modem and a telephone line to dial out to the Internet? Do different members of your MIS department need access to a
modem to download patches and drivers from vendors? How can you create the
equivalent of an inbound modem pool for outbound use? WINport, from LANSource
Technologies, is the product that can meet all these needs.
WINport is a modem-sharing program that includes both a server component
and client components. On the client side, WINport installs a redirector that
fools your operating system into thinking a real modem is connected to your COM
port. This redirector then communicates with the server software over your
network to establish your communications session, as shown in Screen 1.
Redirectors are available for Windows NT, Windows 95, Windows 3.11, and MS-DOS.
The server side requires an NT 4.0 or NT 3.51 machine for operation. The
software runs over a TCP/IP, IPX/SPX, or NetBEUI network.
The beauty of WINport is that all of your existing communications software
will work with the software. For instance, if you use NT or Win95, you can use
the Windows Dial-Up Networking (DUN) component to access the Internet through
WINport. You can even use a communications program such as HyperTerminal to dial
vendor bulletin board systems (BBSs) for updated patches and drivers.
Dialing for Dollars
Installing and setting up WINport requires a little bit of work, but is not
overly difficult. I installed the server software on my NT 4.0 server and used
my Win95 machine as the client. I then used Hilgraeve's HyperACCESS
(HyperTerminal's big brother) and DUN to test WINport. I installed and set up
the software in less than 15 minutes.
After you complete the install process, you must configure the software and
make it operational. This process takes a little more planning than installation
does, especially when you decide to implement security, because of the variety
of security options.
WINport has extensive security to let you tailor access to your outbound
modem pools. At the basic level is user- and group-level security. This security
level operates similarly to NT's user and group-level security. You can permit
or deny access to specific modems or, if you create modem groups, specific
groups of modems. Using this level of security lets you ensure that a modem will
always be available for high-priority users on your network. WINport lets you
authenticate users based on their network username or a separate WINport server
sign-on.
In addition to modem access restrictions, you can restrict dialing for both
users and groups. Dialing restrictions include the ability to dial long-distance
numbers, specific area codes, or local numbers. This feature lets you prevent
abuse of your telephone network. For example, by limiting who can dial
long-distance numbers, you can prevent your users from running up expensive
phone bills. Naturally, if you decide not to restrict dialing, WINport still
maintains a log of all activity, so you can track abuse should it occur.
But Wait, There's More
LANSource includes RASport for free with WINport. RASport is LANSource's
Remote Access Service (RAS)-sharing utility for NT. Using this utility, you can
share your WINport modems with NT RAS for dial-in access. The benefit of this
utility is that you do not need to dedicate one or more of your modems in your
modem pool to RAS and the others to WINport. With RASport, all of your modems
can work with both WINport and RAS for inbound and outbound calls.
You can integrate WINport with FAXport, LANSource's fax-sharing program. If
you integrate all three components--FAXport, RASport, and WINport--your entire
user community can share a single modem pool for fax, data, and RAS
capabilities. This combination can save you thousands of dollars in extra modem
costs, and LANSource offers special packages that let you purchase all three
products at a reduced cost.
WINport is a highly versatile, extremely useful program. It is a system
utility that nearly every systems administrator has searched for since the
advent of modem communications on PCs.
