ISSUE
What Is NetWare Connect?
NetWare Connect is a server based solution for remote
computing. It supports remote node and remote control.
REMOTE NODE
All data including network protocols is transferred back and
forth over the communications link.
REMOTE CONTROL
Only keystrokes and screen updates are transferred over the
communications link.
Netware Connect allows multiple remote users to access
NetWare LANs, and enables LAN workstations to access host
computers via telephone lines, ISDN lines, leased lines,
X.25 packet-switched networks, or direct connections.
NetWare Connect provides the following three services:
- (ARAS) AppleTalk Remote Access Service (ARAS)
- (NCS) NASI Connection Service
- (RNS) Remote Node Service
ARAS and RNS support Macintosh and DOS clients,
respectively, to dial in and become remote nodes on the LAN.
NetWare Connect supports AppleTalk, Internetwork Packet
Exchange (IPX), and Transmission Control
Protocol/Internetwork Protocol (TCP/IP) protocols.
NCS establishes a logical connection between a NetWare
Connect port and a DOS or Microsoft (MS) Windows
workstation. This connection enables LAN workstations to
dial out of the network with third party applications using
a pool of modems on the server. Similarly, dial-in users
can use a third-party application to remotely control a
dedicated workstation on the LAN via NCS.
Each of the NetWare Connect services on the server requires
a corresponding client component that is installed on the
workstation:

ARAS AppleTalk Remote Access
NCS NASI.EXE and third party
applications
RNS NetWare Remote Node (NRN) and the
Dial utility
Refer to Workstation Requirements below for information on
the availability of the workstation software.
NetWare Connect Features
The primary features in NetWare Connect are:
- Dynamic port allocation: Ports are dynamically
allocated as users require them. Ports used for
incoming calls may also be used for outgoing calls, but
not simultaneously.
- Resource pooling: NetWare Connect maximizes
communication resources by sharing modems, multiport
adapters, telephone lines, multiplexers, and X.25
virtual circuits. Ports need not be dedicated to
specific services. The Service Selector module in
NetWare Connect automatically routes incoming calls to
the appropriate service.
- Support for modem independence: The modem
independence feature allows NASI users to use the same
generic modem initialization regardless of the port and
modem type they connect to in NCS. This feature makes
it easier for third-party applications to establish
connections to NCS.
Although the NetWare Connect administrator must select
the types of modems attached to the NetWare Connect
ports, users can specify any modem type in their
third-party applications regardless of the modem type
connected to the NetWare Connect port.
- Security: NetWare Connect enables you to limit users
or user groups to accessing specific services or ports.
You can also restrict services by ports and set maximum
connection time and dialback parameters -- for example,
you can force callers to dial back to a specific
number.
- Management: Simple Network Management Protocol
(SNMP) support allows NetWare Connect to forward alerts
to Novell's NetWare Management System (NMS) product.
If an IBM host is on the LAN, NetWare Connect alerts
are forwarded to the NetView console, as well.
- Audit trail maintenance: NetWare Connect maintains
an audit trail that records information about each
connection for example, the time at the start and end
of the connection.
- Scalability: NetWare Connect allows you to add port
licenses to a previously installed system without
having to reinstall the product.
- Development platform for third-party services:
NetWare Connect provides an open platform on which
third-party communication services can be developed.
NetWare Connect Licenses
NetWare Connect can be purchased with the following
licenses:
- 2 ports
- 8 ports
- 32 ports
You can customize the number of ports by installing two or
more licenses on a single server. A maximum of 64 ports is
supported on a single server. Although NetWare Connect
allows you to install more ports, doing so may degrade
performance.
NetWare Runtime software is bundled with the 8- and 32-port
licenses of NetWare Connect. The ports that NetWare Connect
uses can be COM ports built into the communications server,
ports on a communications adapter, or virtual connections
provided through an X.25 adapter.
SERVER REQUIREMENTS AND RECOMMENDATIONS
NetWare Connect requires the following hardware and
software.
Hardware Requirements
A NetWare server requires the following hardware to run
NetWare Connect:
- An 386 or greater PC. NetWare Connect should operate
on any file server tested and approved by Novell Labs.
Appropriate LAN and video adapters must be installed.
- At least one standard serial port or one of the
communications adapters listed under Communications
Adapters below.
- Appropriate communications hardware, such as modems,
multiplexers, null modem cables, analog telephone
lines, or leased lines.
- In addition to the memory required for the server,
you need an additional 2 MB of RAM to support 64 ports.
- A minimum of 7 MB of disk space. Additional disk
space is required to store the audit file. Because the
audit file grows with each connection and
disconnection, NetWare Connect requires more disk space
the more it is used.
If you install the Novell ElectroText online version of the
NetWare Connect 1.0 Administration Guide, you will need an
additional 12 MB of disk space.
SOFTWARE REQUIREMENTS
To install NetWare Connect, you need the following software:
- NetWare Connect
- DR DOS 6.0 (or greater) or MS-DOS 3.3x (or greater)
- NetWare 3.1x or greater, or NetWare Runtime 3.1x or
greater
NetWare Runtime is bundled with the 8 and 32 port license of
NetWare Connect. It is not packaged with the 2 port NetWare
Connect.
WORKSTATION REQUIREMENTS
A remote PC dialing in to become a remote node on the LAN
(NRN dial-in) requires the following hardware and software:
- An IBM PC, XT, AT, PS/2, or compatible computer with
a high capacity (1.2MB, 5.25" or 1.44MB, 3.5") disk
drive and an optional hard disk. A hard disk is
recommended if you will execute NetWare utilities from
the remote PC.
- A modem. See the list.
- At least one COM port or an equivalent serial
adapter.
- DR DOS 6.0 (or greater) or MS-DOS 3.3x (or greater).
- NRN and the DIAL utility provided with NetWare
Connect. These files are installed during NetWare
Connect installation on the server in the
SYS:SYSTEM\NRN subdirectory. All the files in this
subdirectory must be copied to the remote PC.
- NetWare utilities provided with NetWare. To make the
best use of the line speed, copy commonly used
executables such as LOGIN.EXE, SLIST.EXE, MAP.EXE, and
ATTACH.EXE onto the remote PC.
A remote Macintosh dialing in to become a Macintosh node on
the LAN requires the following hardware and software:
- A Macintosh computer with at least 2 MB of memory.
- OS version 7.0 or later.
- A modem. See the list below.
- AppleTalk Remote Access software. This product must
be purchased from Apple.
- The Set ARAS Passwords utility provided with NetWare
Connect. This utility is shipped with NetWare Connect
on a Macintosh disk. To make the utility available to
remote users, the administrator can do one of the
following:
- Copy the utility from a Macintosh on the LAN
onto a NetWare server that supports Macintosh Name
Space.
- Make copies of the utility and distribute it to
users on diskette.
A NASI workstation (NCS dial-out) on the LAN dialing out
requires the following hardware and software:
- A regular NetWare LAN workstation with at least 640
KB of memory.
- Access to NASI.EXE. When you install NetWare
Connect, NASI.EXE is copied to SYS:SYSTEM\NCS. Copy the
NASI.EXE file to the SYS:PUBLIC directory so that users
can access it.
- A third-party application. The third party
application must support NASI or interrupt 14. For a
list of third party applications, see below.
If you are using interrupt 14 applications, you need access
to the Int14 Redirector provided with NetWare Connect. The
files for the Int14 Redirector are installed in the
SYS:SYSTEM\NCS subdirectory. Copy the files to the
SYS:PUBLIC directory so that users can access it. The Int
14 Redirector supports standard IBM BIOS interrupt 14
function calls.
A Remote PC or a Macintosh computer dialing in to a
dedicated PC on the LAN requires the following hardware and
software:
- A communications program compatible with either a
remote control application or an application server
that supports NASI and runs on a dedicated PC on the
LAN.
For a list of remote control applications or application
servers, see page 12.
If you are running NetWare Access Services on the dedicated
PC on the LAN, the remote PC and the Macintosh computer can
run the ONLAN/PC and ONLAN/MAC software, respectively,
provided with NetWare Access Services.
- A modem. See the list below.
COMMUNICATIONS ADAPTERS
NetWare Connect supports the COM ports on the server or
third party communications adapters. Communications
adapters installed in the server support connections via
direct cable, modem, multiplexer, and X.25 public data
networks.
For X.25 connections, use the Novell Synchronous+ Adapter
that is available in three types of serial interfaces: V.35,
RS-422, and RS-232.
We recommend using the following adapters that support the
standard RS-232 serial interface.

NetWare Access Services 1.3
WinView for Networks
AUTOMATING NASI CONNECTIONS
When you load NASI.EXE, it prompts you for a NetWare
username, password, and session name unless you have
disabled the prompting by specifying the /ns (no security)
option.
If you disable the prompts with the /ns option and use the
features in NCS, the third-party application must provide
security with the NASI Extended Function SetSessionName.
To provide security and automate the NASI connection,
specify the following options when you load NASI:
/n="USERNAME" /p="PASSWORD" /s="SESSION_NAME"
Replace USERNAME with your NetWare username, PASSWORD with
the NetWare password, and SESSION_NAME with a unique string
of up to 16 alphanumeric characters without spaces
describing your session. All three entries must be enclosed
with quotation marks.
If you do not have a password specified, you must enter
/p="".
To run NASI from a batch stream, create a file that contains
the NetWare username, password, and session name in that
order. All three entries must be terminated with a carriage
return.
For example:
"supervisor"
"mypasswd"
"session1"
Then at the DOS prompt, enter
nasi < filename.ext
Replace FILENAME.EXT with the name of the file and the
extension that contains the options. Note that storing the
NetWare username and password in a batch file to automate
login may compromise security.
DIALING BACK AND ENABLING MODEM COMPRESSION FOR NCS
NCS supports forced dialback only when the dialback number
is configured on the server. Initially, modem compression
is disabled on a dial-in port. However, if NCS performs
dialback, compression is enabled. This capability applies
to ports that are members of the DIAL-IN group. If you are
dialing in to a port that does not belong to the DIAL-IN
group, then dialback operations are handled by third-party
applications.
TROUBLESHOOTING NRN
Problems Establishing Connections
If you have problems establishing a connection to NetWare
Connect using NRN, check the following:
- Make sure the frame type specified in the Dial
utility (DIALCON) is identical to that specified in RNS
on the server.
- Make sure the interrupt (IRQ) values used by NRN
driver do not conflict with the IRQ values used by
other hardware devices on the remote PC.
- Make sure the modem type and data rate selected are
correct.
Other Considerations
- If you modify port configurations after you load NRN,
you must reload NRN for the changes to take effect.
- After establishing a connection, if the remote user
fails to attach to a NetWare server, edit the NET.CFG
file to include the following command. (This command
is required if you installed NetWare Connect on a
NetWare Runtime server.)
preferred server=server_name
Replace server_name with the name of the server that
you are logging in to.
- If you are running NRN on a video graphics array
(VGA) monochrome monitor, enter the following command
at the DOS prompt to change your VGA monochrome to
standard monochrome:
mode co80
NOTES ON COMPATIBILITY AND USABILITY
The following information may apply to your NetWare Connect
environment.
Remote Installation
Do not install NetWare Connect remotely on NetWare Runtime
3.11.
Communication Executive 1.2 and NetView
If you have NetWare Connect and the Communication Executive
1.2 running on the same server, then NetWare Connect alerts
are not directed to the NetView console. Upgrade your
Communication Executive software to version 1.3 to view
NetWare Connect alerts on the NetView console.
NetView and NetWare Runtime
The NetView software bundled with NetWare Runtime 3.11 is
incompatible with NetWare Connect. To provide support for
NetView, download the NetView files from the Client Kit
section of NOVFILES.
NetExplorer and NetWare Connect
NetExplorer is a component of NMS. If you install
NetExplorer from a version of NMS earlier than 1.15 on the
server running NetWare Connect, you cannot load ARAS and
RNS. To enable these services to load, you must upgrade
your NMS software to version 1.15 or greater.
X.25 Connections
- To configure for X.25 support in NetWare Connect,
load the X.25 driver before you load AIOPAD.
- The X.25 support in NetWare Connect is incompatible
with the NetWare MultiProtocol Router (MPR) 2.0.
Upgrade MPR 2.0 to version 2.1 or greater before you
install NetWare Connect.
OnLAN/MAC via AppleTalk Remote Access
Make sure you are using OnLAN/MAC v1.3 if you are running
OnLAN/MAC over an ARAS connection.
