- The BBSNet Product
-
- BBSNet provides real-time Internet connectivity to most popular BBSs.
- This includes incoming access (from the Internet) via the Telnet
- protocol, as well as Telnet, FTP, Archie and Gopher access to the
- Internet for dial-up users.
-
- BBSNet uses an existing Internet connection in conjunction with Novell
- Netware 386 version 3.11 or 3.12 to provide this capability to MS-DOS
- compatible BBS systems.
-
- Incoming Telnet
-
- Telnet, the Internet standard for remote login, is an application
- protocol that runs on top of TCP/IP. Internet users with networked Unix,
- DOS, Vax and other workstations can Telnet to your BBS and log in as if
- they had dialed your system directly with a modem.
-
- Non-networked users can dial a local terminal server, POP (Point of
- Presence) or other network service (such as Delphi) with their existing
- modem and terminal emulation software. Once connected via modem, they
- can issue the Telnet command to connect to your BBS as if they had
- dialed it directly with a modem.
-
- One of the biggest advantages of providing incoming Telnet access to
- your BBS is that you open up your system to a potential 10 million
- `callers', the majority of whom will be making a local telephone call to
- reach your BBS via the Internet.
-
- Users who Telnet into your BBS access it in the same manner as regular
- dial-up users. File transfers can take place through the Telnet
- connection if the user's terminal server is properly configured.
-
- Users coming from networked Unix systems can also use the File Transfer
- Protocol (FTP) to download files from or upload files to your BBS.
-
- Outgoing Telnet
-
- Your dialup users can Telnet to other hosts on the Internet as well. In
- many respects, your BBS becomes a terminal server for your local
- callers.
-
- Callers execute a `telnet door' (depends on BBS type) to access the
- Telnet client software. They enter the Internet name of any remote host,
- or select from a list of popular sites which you configure.
-
- FTP / Archie
-
- FTP (File Transfer Protocol) is the Internet standard for file transfer.
- Archie is a search mechanism that works in conjunction with anonymous
- FTP archives, allowing users to search for files on multiple anonymous
- FTP archives.
-
- BBSNet provides a combined FTP/Archie client for dial-up users. Callers
- may FTP directly to a remote site of their choice, or ask the Archie
- client for assistance in locating a file. Once found, Archie instructs
- the FTP client where to locate the selected file and automatically
- retrieves it.
-
- The selected file is returned to the BBS and downloaded to the caller
- using Zmodem.
-
- Callers may also upload files using Zmodem, then use the FTP client to
- transfer the files to a remote host.
-
- Gopher
-
- Gopher, a distributed information retrieval system, is fast becoming the
- hottest item on the Internet. Gopher users can obtain information from
- around the world on a variety of topics.
-
- BBSNet includes a gopher client application. Retrieved information can
- be displayed on the screen as it is obtained, or saved in a file for
- subsequent downloading at the end of a session.
-
- Questions and Answers
-
- Which BBSs are supported?
- BBSNet supports most popular MS-DOS based systems, including: PCBoard
- (/M version required for incoming Telnet), The Major BBS (advanced LAN
- option required for incoming Telnet), WildCat (Version 4 required for
- incoming Telnet access), Searchlight, RoboBoard,TurBoard and other
- Fossil compatible BBSs.
-
- If your BBS can run on top of a Fossil driver, it can support incoming
- Telnet access.
-
- If your BBS can execute a DOS door, and provide a Fossil interface to
- your async port, it can support outgoing telnet, ftp/archie and gopher.
-
- What other software/hardware do I need?
- The first release of BBSnet operates as a series of Netware NLMs.
- Therefore you will need a Novell Netware 386 3.x (fileserver version 4.x
- is not supported at this time). Often a 5-user version of Netware 386
- will be sufficient, depending on the number of nodes you have. A 5-user
- version of Netware 386 3.x can be found mail-order in the $400 to $500
- price range.
-
- BBSNet uses the TCP/IP stack included in Netware 386, therefore
- Lantastic, Netware LITE and Personal Netware are not supported. However,
- Lantastic version 6 running with a network server is supported.
-
- How does my BBS connect to the Internet?
- Figure 1 represents the typical method for connecting your BBS to the
- Internet.
-
- How do I get an Internet Connection?
- You should contact several Internet service providers to find one that
- matches your needs. The book, Connecting to the Internet, is one of
- several information sources which will help you find a service provider.
- See the listing at the end of this newsletter for book references.
-
- What kind of Internet connection do I need?
- At a minimum you will need a high-speed SLIP or PPP dial-up connection.
- You may also use a dedicated 56K or T1 leased-line, though dedicated
- circuits are expensive.
-
- Because you can not connect a SLIP/PPP line directly to a Netware
- server, you will need at least two IP addresses for your site, one for
- the Netware server and one for your router.
- This means that individual dial-up SLIP/PPP connections are not
- suitable. Ask your service provider for a Class C address (which
- actually consists of 256 possible IP addresses).
-
- How do I connect to the Internet?
- Your Internet service provider will probably have minimum hardware
- requirements for leased-line and dial-up access. You will most likely
- need some kind of router.
-
- The router is represented as the left-hand box in figure 1. It connects
- your local ethernet (heavy black line) to the Internet through a leased-
- line or dial-up connection.
-
- For dial-up SLIP/PPP connections, commercially supported products such
- as the Telebit Netblazer, or Rockwell NetHopper are good, if not
- expensive, options for connecting your system to the Internet.
-
- Another good possibility for SLIP/PPP is using an Intel based BSD Unix
- system to route packets between the SLIP/PPP connection and your local
- ethernet. BSD Unix for Intel can be obtained relatively cheaply, runs on
- minimally configured 386 or better processors and can perform other
- duties such as mail and Usenet news handling.
-
- There are two free BSD work-alike Unix's for Intel available from some
- Internet archives (also available on CD-ROM), Linux and 386BSD.
-
- A very good, commercially supported BSD Unix for Intel can be obtained
- from Berkeley Software Design, Inc. (800)800-4BSD, (703)204-8086.
-
- How many user's can be connected?
- The answer to this question depends on the type of Internet connection
- you have, what users are doing with the connection, and the number of
- 'nodes' you have.
-
- A high-speed dial-up SLIP/PPP connection should be able to support up to
- four or five interactive Telnet users (either incoming or outgoing) so
- long as they are not transferring files. As soon as one user begins a
- file transfer through the Internet connection, the echo delay time for
- the other users will typically be intolerable.
-
- Therefore, if you expect heavy file transfer activities to and from your
- BBS, you should consider a 56K or better dedicated Internet connection.
-
- Can I use Desqview or OS/2?
- Yes. Both Desqview and OS/2 are supported. You may run multiple copies
- of your BBS under either system for both dial-up and Internet users.
-
- How does BBSNet work?
- Figure 1 provides a rough representation of an incoming Telnet session
- (Internet to BBS).
-
- A remote Internet user Telnets to your Netware server. Telnet is a
- TCP/IP protocol, and its data packets are shown entering the Netware
- server from the left-hand side.
-
- The BBSNet NLMs executing on the Netware server process the Telnet
- connection and extract the user's data (ie: keystrokes) from the
- protocol stream. These keystrokes are then sent back out on the local
- ethernet using the SPX protocol (a native Netware protocol) to the BBS
- node to which the remote user is attached.
- When a remote user first initiates a connection to your BBS, the BBSNet
- NLMs search the local ethernet to find the first physical node (PC) with
- a free virtual node.
-
- For example: Given two PCs, each running Desqview, with four copies of
- PCBoard running on each of those PCs. The BBSNet software will ask the
- first PC if one of those four PCBoard copies is not in use. If all four
- are in use, BBSNet will ask the second PC if any of it's copies of
- PCBoard are not in use. This continues until all PCs running the BBSNet
- software have been checked, or until a free virtual node (copy of
- PCBoard) has been found.
-
- If no nodes are free, the remote Telnet user is asked to `call back'
- later.
-
- For dial-up users accessing the Internet, the reverse process is used.
- A custom DOS Door communicates with the Netware server. The BBSNet NLMs
- on the Netware server convert the SPX packets into Telnet, FTP, Archie
- or Gopher requests and sends them out to the Internet using TCP/IP.
-
- What about electronic mail?
- BBSNet does not currently support electronic mail. However, an SMTP
- option will be available as an add on feature at a later date. SMTP
- (Simple Mail Transport Protocol) is the Internet standard for the
- exchange of mail messages.
-
- Our SMTP option will allow you to send and receive mail using your
- Internet connection.
-
- In the meantime, you may continue to use your existing UUCP connection
- (if you have one) to send and receive mail. Or, you may set up a local
- Unix box (several options mentioned previously). This Unix system can
- communicate with the Internet using SMTP, then use UUCP to communicate
- with your existing UUCP `tosser' if you have one.
-
- What about Future Development?
- As previously mentioned, we'll be supporting SMTP electronic mail.
-
- For small BBSs, we will move the NLMs from Netware to OS/2. Using IBM's
- TCP/IP for OS/2 in conjunction with BBSNet, this combination would
- provide simple connectivity for a one to five node DOS based BBS under
- OS/2 with dial-up SLIP/PPP.
-
- How much does BBSNet cost?
- The BBSNet package is licensed based on the number of simultaneous
- Internet connections. For example one incoming Telnet connection and one
- Gopher session count as a total of two simultaneous connections.
-
- Connections Price
- 2 $325
- 5 $525
- 10 $825
- 15 $1025
- 20 $1325
- > 20 $275 /each additional
- 5 user pack
-
- When will BBSNet be available?
- We expect to begin shipping the software in early August, 1994.
-
- Our software comes with a 60-day money back guarantee of satisfaction
- and one year of free upgrades.
- Where can I get more information about the Internet?
- The Online User's Encyclopedia Bulletin Boards and Beyond, is a good
- reference guide for the kinds of things you can do on the Internet.
