- LANtastic Network Operating System Version 4 Compatibility
- Bulletin
-
- Product Reviewed: Pathway/Access Release 2.0 and WIN/ROUTE
- Release 2.1 by The Wollongong Group
- Classification: TCP/IP Connectivity
- Date: 04/03/91
- Engineer: JAG
-
-
- Compatibility Statement:
- Pathway/Access Release 2.0 and WIN/ROUTE Release 2.1 are
- compatible with LANtastic NOS 4.xx.
-
- Product Overview:
- The Pathway/Access and WIN/ROUTE products can be used together to
- provide TCP/IP connectivity between a PC-based LANtastic network
- and a varity of machines that are connected on an Internet
- network. A dedicated PC running WIN/ROUTE provides the link
- between the LANtastic and the TCP/IP world, while Pathway/Access
- provides TCP/IP transport layer and applications services for the
- LANtastic side of the link. In general, the Pathway drivers
- convert LANtastic's standard NetBIOS packets into TCP/IP format,
- allowing IP-based applications to establish links via the
- WIN/ROUTE gateway. We tested and found compatible the TELNET
- terminal emulation program, FTP file transfer utility, FTPD file
- transfer server, PING network communication test, LPR remote
- printing utility, and the Berkeley R-series commands RCP (remote
- copy), RSH (remote shell), and RLOGIN (remote login).
-
- Test Equipment Configuration:
- The following machines were used for Pathway/Access-WIN/ROUTE
- testing. All machines running LANtastic used Artisoft AE-2 or
- AE-3 NICs and testing was completed using LANtastic NOS v4.1.
- Machines running as LANtastic peer-to-peer servers are designated
- by (S).

- A Western Digital WD8003E network adapter was the network
- interface for the UNIX system. The dedicated router used both an
- AE-2 and a WD8003E card to route packets between the DOS and UNIX
- systems.

- Product Installation Notes:
- Installation of both Pathway/Access and WIN/ROUTE is accomplished
- by running a batch file included on the installation diskettes.
- We recommend Installing WIN/ROUTE first, since the router must be
- operating properly before TCP/IP services can be used from a
- LANtastic station. The router PC must be dedicated to the
- function of routing and cannot be used as a LAN workstation.
- It requires two LAN adapter cards, one for the LANtastic side of
- the network and one for the TCP/IP side. In the example depicted
- in Figure 1 above, the LANtastic interface card is an Artisoft
- AE-2 or AE-3 adapter and the Western Digital WD8003E card is used
- for the TCP/IP interface. WIN/ROUTE installs to a directory
- called WINTCP from a single program diskette. During
- installation, the install routine appends the following line to
- the CONFIG.SYS file:
-
- DEVICE=C:\WINTCP\WINTCP.SYS
-
- The WINTCP.SYS driver is really a data structure that holds
- configuration information for the routing TCP/IP kernel,
- ROUTETCP.EXE. Before the kernel can be run for the first time,
- this information needs to be configured, or "customized," via the
- CUSTOM program. The WIN/ROUTE documentation covers the
- appropriate values for the configurable parameters, but there are
- some that must be set to specific values. These are:
-
- 1) Set the number of interfaces to two (2). This number is the
- number of network adapter cards that are installed in the
- router.
-
- 2) Set the Internet (or IP) address for each interface. The
- actual addresses depend on what IP addresses are assigned to
- the site. If there are no IP addresses officially assigned
- to the site and the LAN will not be connected to a larger
- network, these addresses can be arbitrarily determined. You
- must, however, make sure that the correct IP address is
- assigned to its proper interface number. See the "Hardware
- customizing Procedure" section in Chapter 2 of the
- "WIN/ROUTE Installation and User Guide" for details. Refer
- to the WIN/ROUTE and Pathway/Access documentation for
- general information regarding IP addressing.
-
- Once customization is complete, reboot the PC to effect the new
- configuration.
-
- For Pathway/Access installation there are two diskettes, one each
- for the network interface drivers and the application programs
- (e.g. FTP, TELNET, etc.). The installation process places the
- files in a directory named PATHWAY on the hard drive.
- Additionally, it appends a line to the CONFIG.SYS file that loads
- the PWTCP.SYS driver. This driver is similar to the WINTCP.SYS
- driver and contains configuration information that is used by the
- Pathway kernel program, PWTCP.EXE. As with the WINTCP.SYS
- driver, use the CUSTOM program to customize the PWTCP.SYS
- information before it can be used by the kernel. Variables such
- as the Internet address, host name, and user name for a
- particular PC are set using CUSTOM. Appropriate values and
- ranges for these settings are documented in the Pathway/Access
- Installation Guide, but there are some that must be set to
- specific values to ensure correct network operation. These are:
-
- 1) The Default Gateway address must match the Internet address
- of the LANtastic interface on the router. Set it using the
- "Set default gateway's address" selection on the main CUSTOM
- menu.
-
- 2) Using the "Select program parameters" selction from the main
- CUSTOM menu choose the "Set expert parameters" on the
- Program Customization menu. Set the number and size of
- "large packet buffers" to 10 and the size to 512.
-
- Reboot the PC once customization is complete to load the new
- values.
-
- Product Execution Notes:
- Starting the router is a matter of running the drivers for the
- adapter cards and then bringing up the routing kernel and the
- routing software. As mentioned above, the router must be a
- dedicated machine. In the example in Figure 3 on page 2, the
- AEX.EXE and AILANBIO.EXE TSRs are loaded as the basis of the
- LANtastic network interface. Wollongong's NB_DRV.EXE is loaded
- on top of them in order to provide NetBIOS to IP translation for
- the kernel. The other interface - via the WD8003 adapter - is
- pure IP, so Wollongong's WD80X3.EXE TCP/IP driver is all that is
- needed. The ROUTETCP kernel is then loaded to provide basic
- TCP/IP transport layer services, and WINROUTE runs as the top
- layer, providing the packet routing function. The following is a
- sample batch file for loading all the required software for the
- router:
-
- AE2 IOBASE=340 IRQ=2
- AILANBIO
- NB_DRV -N:60
- WD80X3 -I:3 -M:D800 -B:280 -N:61
- ROUTETCP
- WINROUTE
-
- Note: In order for the router and the UNIX computer to
- communicate properly, the address of the router must be added to
- the TCP/IP routing table on the UNIX machine. Refer to Chapter
- 3, "Setting Up Routes," in the WIN/ROUTE Installation and User
- Guide for specific instructions.
-
- Figure 2 on page 2 shows the protocol stack for the PCs on the
- LANtastic side of the link. As it suggests, all of the LANtastic
- TSRs are loaded before running any of the Pathway/Access
- programs. The LANtastic NOS TSRs may be loaded into upper memory
- on machines with support for upper memory functions, but the
- Pathway TSRs should be loaded in low DOS memory. After loading
- the desired NOS programs, run the Pathway NB_DRV.EXE and
- PWTCP.EXE programs. As with the router, the NB_DRV driver
- provides IP to NetBIOS translation, and PWTCP is the support
- layer for TCP/IP applications. The following batch file could be
- used to install both LANtastic and Pathway/Access on a typical
- PC:
-
- AEX IOBASE=340
- AILANBIO
- REDIR TEST LOGINS=10
- NB_DRV
- PWTCP
-
- Once the above batch file has run, TCP/IP applications such as
- PING, FTP, and TELNET can be used to access the IP network.
-
- Compatibility Notes:
- Artisoft has successfully tested the PING, FTP, FTPD, TELNET,
- RCP, RSH, RLOGIN and LPR functions in the configuration outlined
- in the Test Equipment Configuration section above. In addition,
- Pathway/Access includes a Windows 3.0-based program that includes
- FTP, TELNET and LPR services. We tested this utility and also
- found it compatible with LANtastic and LANtastic for Windows.
- Running FTPD in "background mode" (using the -b command line
- switch) is not supported.
