-
- The primary purpose of a FAQ is to preserve network bandwidth by answering
- Frequently Asked Questions. A FAQ's second purpose is to provide an altruistic
- public service to users and vendors.
-
- The Amiga Guide version of this FAQ is available on Aminet in the
- /pub/aminet/docs/help directory.
-
- Due to the method I'm using to write the FAQ, marking the margins to indicate new
- material is not feasible. Look for new questions towards the end of each list.
- Also look for "!!!!", strings of exclamation points represent new material or news
- flashes.

- --------------------
-
- What is a network?
-
- short answer: Interconnected computers.
-
- A network is two or more computers that can interconnect in a peer to peer or
- client to server fashion most often over a shared and often virtual connection.
- This is in direct contrast to the old terminal to host hard wired connection. A
- network can still support terminal to host connections via terminal emulators or
- terminal servers, but provides much greater flexibility in switching connections.
-
- A network is accomplished using three basic components. Hardware, protocols
- (software), and Applications (useful software ;-) Each of these is actually
- comprised of several layers, but we won't worry with the details. There are many
- books on the subject as well as technical specs for the standards. But you will
- need some knowledge of the lingo in order to configure your networking software
- correctly. Consulting with your LAN administrator or WAN service provider is also
- highly advisable for checking your network software configuration.
-
- Among the many books on the subject is "Connect your Amiga!" by Dale Larson of
- IAM . I mention Dale's book because it explicitly deals with the Amiga whereas
- most of the rest are generic.
-
- The concept of layers is very important to networking and computer designs as
- well. Each layer "protects" the layer above from the layer below so that one layer
- can change with minimum impact on the upper layers. In some cases this protection
- is so good that an application may not know that it is running on different
- hardware. The OSI network model defines seven layers, but we are going to reduce
- it to three broad categories.

- ------------------------
-
- Hardware
-
- At the heart of a network is a shared cable often called a Backbone. In the simple
- case this is a PARnet cable to connect two Amigas via the parallel port. Both
- machines share the cable. A more complex example is an ethernet cable which
- without special equipment can be 1000ft in length or more with a hundred or so
- computers attached all interconnecting at once. This is known as a LAN or Local
- Area Network. A cheaper but far more limited LAN Backbone is Localtalk which
- Apple unleashed upon the world.
-
- bridges, routers, and gateways Oh my!
-
- To overcome the distance and node limitation of ethernet wiring you need at least
- a bridge which basically acts as a repeater. A bridge can also do a limited
- amount of filtering so that traffic between the LAN segments is more efficient.
-
- There are also distance limitations with bridges, so a more complex piece of
- equipment is needed called a router. A router provides many more tools for
- controlling the flow of information between segments, and can even provide some
- level of security. Special security configurations of routers are know as
- firewalls. For really long distances leased lines or satellite links are used
- between the routers thus forming a Wide Area Network or WAN. These links are
- usually provided by common carriers or some WAN providers .
-
- This all works great as long as the two machines are the same brand, but since
- there is more than one vendor there is more than one "language" called a protocol
- for communicating. A gateway must be used to translate between the protocols. As
- an alternative to a gateway, some routers are able to handle multiple protocols
- at the same time. Gateways are also used most heavily for converting between
- electronic mail formats or to go between two different physical media such as
- ethernet and Localtalk or ethernet and SLIP. See the Envoy specific question
- section for an example of an ethernet to SLIP gateway.
-
- The gateway provides access to other parts of a network that would not otherwise
- be directly accessible. A router is dedicated to keeping track of routes through
- gateways and other routers to various domains. On large networks your default
- gateway will often point to a router.
-
- The distinction between gateways, routers, and bridges is not absolute since many
- of the functions of each can be included in a single product. In fact some
- companies call their product a brouter because it performs both as a bridge and a
- router.
-
- Computers use numbers, but humans use names. Therefore, another device that is
- used on large networks is called a _NAMESERVER_. A nameserver maintains a
- database of machine names and their corresponding numeric addresses. The
- nameserver allows the computer to look up the numeric address when you use a
- name. In addition to the nameserver you can maintain a HOSTS file locally which is
- used first by your computer when trying to translate a name into a number.
-
- The above terminology is slanted towards the TCP/IP protocol because that is (for
- better or worse) what you will most likely encounter.

- ethernet cable
- ------------------------------------
-
-
- While looking through the What's New page of Mosaic, I stumbled across the
- Ethernet Web Page. It references an ethernet FAQ from the comp.dcom.lans.ethernet
- news group. So if you don't find your answer in this crude introduction then try
- their FAQ.
-
- the URL for the web page is:
-
- http://wwwhost.ots.utexas.edu/ethernet/ethernet-home.html
-
- the gopher URL for the FAQ is:
-
- gopher://mojo.ots.utexas.edu/11/netinfo/ethernet/ethernet-faq
-
-
- An ethernet cable comes in several flavors. The maximum length of your LAN
- segment is determined by which flavor you choose or which flavors you intermix.
- There is twisted pair, thin coax and thick coax ethernet cables. Each of these
- are rated at 10Mbit per second.
-
- Note that this is the TOTAL capacity (bandwidth) of the cable NOT the speed
- between any two nodes. The speed between nodes is determined by how many nodes
- are trying to communicate at any given time. Even with only two nodes
- communicating you will NOT get the entire bandwidth of the cable. The maximum is
- usually only around three Mega bits per second.
-
- The thick coax was the first used. It ran as a backbone through a building with
- taps and drop cables for each node (computer).
-
- Thin coax came into favor because of lower cost and ease of installation. Thus
- thin coax is often called cheaper net. It has a shorter overall maximum length
- than thick. It is routed in a daisy chain style using tee connectors at each
- node. There are adapters to go between thick and thin, but your overall length
- can be reduced to that of thin. There are devices called hubs which may not reduce
- the limit and can provide conversion between one cable type to another.
-
- Twisted pair is the current rage because it can be used for other things as well,
- such as voice. You can wire an entire building with twisted pair and decide at the
- wiring closet what service will be provided. Ethernet over twisted pair is called
- 10BaseT and is most often configured as a star with an ethernet concentrator at
- the center usually in a wiring closet. The concentrator allows for the longer
- length required for a star configuration. Using a concentrator provides the LAN
- administrator a lot of other benefits and options such as diagnostic tools and
- functions for monitoring the health of the LAN segment.
-
- Several grades of twisted pair wire exist. The best class can also carry FDDI
- which is a fairly new high speed token-ring style network architecture. FDDI can
- handle speeds of 100Mbit per second. FDDI is usually carried over fiber optic
- cable for long distances. There are also Gigabit per second network architectures
- for short distance applications such as a cluster of compute servers. As far as I
- know there are NO FDDI or faster adapters for the Amiga at this time.
-
- So the same wire can carry either FDDI or Ethernet so how do they differ? Good
- question. It is obviously NOT just the wire. Ethernet and FDDI are also
- specifications for how the electrical signals will be transmitted and interpreted
- over the wire. The Ethernet spec was originally developed by Xerox and DEC, and is
- now defined by the IEEE standards committee. IEEE 802.3 is one of the main
- ethernet standards in use.
-
- One reason FDDI came into being is that ethernet performance degrades rapidly as
- you approach the capacity of the bandwidth. This means you are limited in the
- number of nodes that a LAN segment can support. Depending on the activity level
- of the nodes you may be able to support as many as 100 nodes on a LAN segment.
- Beyond that and you should consider subdividing into multiple LAN segments with
- bridges and routers.
-
-
- !!!!! new info !!!!
-
- A new wrinkle is FAST ethernet which also runs at 100 Mbs but unlike FDDI it can
- coexist on the same wire as regular ethernet. They even make hybrid cards that can
- do both 10 and 100 Mbs depending on what the host they are talking to can support.
- The catch to FAST ethernet is that it has an even shorter distance limitation than
- regular ethernet. Also, FAST ethernet only runs over category 5 twisted pair or
- thick coax not the thin. Unfortunately there are no FAST ethernet cards for the
- Amiga yet.

- ------------------------
-
- Protocols
-
- A protocol is software that is required to use the physical connection. It is
- responsible for establishing the connection and sending and receiving the data in
- packets. Modem software is a crude example.
-
- The software is called a protocol because there must be cooperating software on
- each end, but they don't have to written by the same vendor. Instead a
- "protocol" for the proper exchange of data is defined and released as a standard
- (such as TCP-IP ) or licensed as proprietary (such as DECnet ). As long as the
- vendor on each end adheres to the protocol a connection can be sustained which
- will support an application.
-
- TCP/IP is in the broadest use for several reasons, but mostly because vendors
- could get and use the standard for basically free. DECnet was very popular
- because of its robustness and the quality of the VAX systems. The low cost,
- graphics power, and lure of a standard operating system drew users to UNIX
- systems which used TCP/IP because of the cost and availability. This has resulted
- in DECnet falling way behind in numbers. Other examples of protocols are
- Appletalk, IPX, and SNA. They also suffer from being proprietary.
-
- Due to the constant growing of the size of the wide area networks (WAN), a more
- robust protocol is required which will support a large number of addresses which
- is the numeric value assigned to each computer on a network. Two approaches are
- being worked currently. One is to revamp and extend TCP/IP while maintaining
- backwards compatibility. The other is an international standards effort called
- OSI Open Systems Interconnect. OSI is moving very slowly which is making it
- difficult to gain vendor support. TCP/IP will almost certainly be enhanced
- regardless if OSI is successful or not.
-
- In addition to these major protocols there are numerous other proprietary
- protocols such as SNA by IBM or IPX by Novell. Some fill special niche
- requirements, and some of them don't scale well to the WAN environment. Some are
- so proprietary they will not run on but a single vendor's hardware.
-
- The latest wrinkle in the protocol world are SLIP and PPP which allow the
- TCP/IP protocol to be used over a modem connection. Typically a remote machine
- such as a laptop is hooked by modem to a new generation of terminal servers which
- can convert between SLIP or PPP and regular TCP/IP. The terminal server is
- connected to both the modem and the LAN. This setup gives the remote user full
- (although slower) TCP/IP access to the LAN.
-
- DECnet can also be configured to use a serial connection.

- TCP-IP
- ------------------------
-
- TCP-IP is a protocol that has been released as a standard which means that
- vendors can implement it independently and freely and yet it still works. The
- standard is defined and described in RFC documents which are available
- electronically. Lots of free source code and the ability to use it royalty free
- make TCP/IP attractive to vendors. It has been implemented by a large number of
- different vendors and therefore is popular on the Internet. For more information
- on the Internet and TCP-IP concepts see ZEN
-
- TCP/IP as the name implies is more than one layer. The IP layer takes care of the
- lowest layers of the protocol and is responsible for talking to the device drivers
- (data link layers). The TCP is one of two "transport" layer protocols which
- handles the packetizing of the data. TCP is a reliable service because it insures
- that the packets are put back into the right order and that they are all received.
- If you send packets "a", "b", "c", then TCP will make sure they are received as
- "abc" and not "bca".
-
- UDP is the other transport protocol and it is unreliable, but has less overhead.
- The applications ride on these lower protocol layers. There are a number of
- applications defined in the TCP/IP standards, but vendors are only required to
- supply the lower layers. See the applications section for a partial list of
- TCP/IP applications. For instructions on using the FTP application see the
- FTP FAQ
-
- TCP/IP standard also provides for programming hooks which can use ports and
- sockets to allow programs to talk to one another over the network. The World Wide
- Web (WWW) and Internet Relay Chat (IRC) are two examples of how these hooks can
- be exploited. Any programmer can use these hooks for their own programs.
-
- See the software by category section for a list of Amiga implementations of
- TCP/IP.
-
- DECnet
- --------------------------
-
- DECnet is a proprietary standard belonging to DEC which is also made up layers in
- a similar manner to TCP/IP. They break up the job quite a bit differently. For
- instance with DECnet there is no need for a separate NFS application. You can see
- a remote nodes disk drives by simply including the DECnet node name in the
- directory command. DECnet has two ways of handling terminal traffic. For the WAN
- you use the SET host function of DECnet, but it is more efficient for local
- traffic to use the LAT protocol. The older model DEC terminal servers only
- supported LAT or asynchronous DECnet. Newer models also support SLIP and PPP
- (check the manuals) since DEC now makes computers that use TCP/IP as well.
-
- TSSnet DECnet is an Amiga implementation of DECnet.
-
- SLIP
- -----------------------
-
- SLIP Serial Line Internet Protocol See RFC 1055 for details. CSLIP adds a
- compression technique. For details read RFC 1144.
-
- SLIP allows your computer to run TCP/IP over the serial port. This allows your
- computer to have a TCP/IP address. TCP/IP applications such as FTP can now use
- TCP/IP to deliver packets directly to your address. An analogy would be instead
- of having to go to the post office to get your mail, you now have a mailbox to
- which the postman can deliver your mail. In more technical terms you are no
- longer a terminal; you have become a node.
-
-
- SLIP is a "data link" protocol. It sits between the serial port and the IP stack.
- It pretty much takes the packets from IP, adds a wrapper to them, and sends them
- out the serial port. It also takes packets from the serial port, unwraps them, and
- passes them up to IP. SLIP has several problems, including the fact that it is
- designed entirely for TCP-IP, and is therefore of limited use for other
- protocols. Too many people ask for "SLIP" when they really want "TCP/IP" with a
- SLIP driver. You have to have both. Just like a terminal program is of little use
- without a serial.device driver.
-
- SLIP is not a full protocol. It fits in one of the layers between hardware and the
- TCP/IP protocol. It acts more like a device driver. It also acts like a protocol
- because it has to be at both ends of the physical link, but it must have the
- TCP/IP protocol in order to talk to the applciations.

-
- PPP allows your computer to run TCP/IP over the serial port. This allows your
- computer to have a TCP/IP address. TCP/IP applications such as FTP can now use
- TCP/IP to deliver packets directly to your address. An analogy would be instead
- of having to go to the post office to get your mail, you now have a mailbox to
- which the postman can deliver your mail. In more technical terms you are no
- longer a terminal; you have become a node.
-
- PPP is the committee-designed protocol which is supposed to be a sort of
- "universal" SLIP. It is intended to replace SLIP, while providing for all sorts
- of conditions, including the ability of use over non TCP/IP protocols. The two
- state machines in PPP are a real pain to implement. UNIX folks love it because a
- PPP implementation exists, and they pretty much type "MAKE" and it works.
-
- PPP's good points:
-
- - PPP users checksums (FCS) SLIP does not
- - PPP allows more than one protocol at a time, SLIP does not
- - PPP automatically negotiates IP addresses, SLIP does not
- - PPP can be used on non-transparent lines (e.g. when XON/XOFF is
- used by the modems), SLIP cannot
-
- Several Amiga versions of PPP are in the works.
-
- A shareware version called ppp.device by Holger Kruse has been released on
- Aminet Downloading "HowToUsePPP.lha" from Aminet probably wouldn't hurt either.
-
-
- PPP is not a full protocol it fits in one of the layers between hardware and the
- TCP/IP protocol. It acts more like a device driver, but it is also a protocol
- because it is required at both ends of the physical link. PPP requires TCP/IP or
- similar protocol to talk to the applications.

- SANA II
- ---------------------------
-
- SANA was an experimental DATA-link and API paper written by Dale Luck for a
- DevCon several years ago. Dale suggested two schemes for creating standard
- interfaces for the data-link layer and protocol stack APIs. After Dale left
- Commodore, the work passed to several other people-- and the "API" part was
- removed. After it had touched several people's hands, SANA-II was put together.
-
- SANA-II is nothing more than a standard for writing device drivers. Having
- something which is SANA-II doesn't help you do networking unless you have a real
- protocol stack communicating through it. FAR too many people have seen
- "SANA-II", and "Amiga networking standard", and assumed too much. It is just a
- device driver standard whose purpose is to prevent networking packages from hard
- coding to specific hardware. This is similar to the reason for packet drivers in
- the PC clone arena. A side benefit to SANA-II is that it allows multiple
- protocols to share the same ethernet card.
-
- UUCP
- ---------------------------
-
- UUCP (Unix to Unix CoPy) is an old protocol used for transferring files between
- un*x boxes. Versions of UUCP were written for other operating systems and
- platforms including the Amiga.
-
- UUCP is not interactive like a terminal program, but more of a batch process. You
- give a list of commands ahead of time and then at the specified time it calls
- another machine, executes the commands which usually sends some files and
- receives what the other machine has for it, and then hangs up. A store and forward
- methodology as opposed to a dynamic constantly available method.

-
- Applications
-
- The applications are the part of the network that a user is most likely to see,
- but are useless without the hardware and protocols. Applications allow a user to
- emulate a terminal, copy files, send electronic mail, browse and search
- databases, and use applications remotely.
-
- Some of the applications are included with the protocol software, but NOT all of
- them. Some applications are extremely difficult and complex to write and therefore
- are commercial products.

- For TCP-IP I also included NNTP, and HTTP which are protocols, but they ride on
- top of TCP-IP and therefore constitute a form of a client-server application as
- opposed to a full protocol.
-
- TCP/IP applications:
-
- """""""""""""""""""
-
- telnet ----- terminal access
-
- telnetd ---- the telnet server which allows incoming telnet
- connections to your machine

- to your machine
-
- SMTP ------- Simple Mail Transfer Protocol (email) or
- Send Mail To People as my friend calls it.
-
- NFS -------- Network File System (remote mount disks)
- PARnet provides a similar service on a much
- smaller scale.
-
- NFSd ------- the NFS server which allows incoming NFS connections

-
- NSLookup -- find address corresponding to a host name or vice-versa.
- Also provides access to other info in the DNS database
-
-
- Finger ----- See who is logged in

-
- Xwindows -- Use graphics programs on a remote system. An attempt at a
- hardware independent terminal emulator. Cost and speed are
- its biggest drawbacks.
-
- NEWS ----- A BBS style messaging system global in scale

-
- html
- ------------------
-
- HTML stands for HyperText Markup Language.
-
-
- HTML is used to build WWW pages which can be accessed locally or served to the
- world using a WWW server running http . HTML files are ASCII text files. The html
- commands are included with the text and are interpreted by the browser rather than
- shown. HTML commands include page formatting and URL links. Universal Resource
- Locators (URL) are the links between this page and other pages throughout the WWW.
- Any page you view with a browser can be saved locally as an HTML text file. These
- files can be edited locally which allows you to cut and paste interesting links
- (URL) into your own HTML page of favorite links.
-
-
- Although studying how other web pages are built can be helpful, it is not the best
- way to learn proper HTML.
-
- There are numerous online documents describing HTML, but for the basics take a
- look at "A beginner's Guide to HTML." For other sources of info on HTML check out
- the WWWFAQ at
-
- http://sunsite.unc.edu/boutell/faq/
-
- CERN wrote the original HTML and HTTP. NCSA wrote Mosaic and added features to
- html. Since HTML is an evolving standard, what works on one browser may not work
- on another browser which uses an earlier version of HTML. HTML 2.0 is the current
- version, and version 3.0 has been abandoned in favor of version 3.2. The reason
- was that the market was changing way to fast for the standards process. There is
- now a more formal organization. For the latest info go to:
-
- http://www.w3.org/
-
-
- Another problem is that certain server/browser vendors like to throw their weight
- around and add neat new features which are not part of the standard. This leads to
- confusion and frustration when someone tries to use a standard browser to access
- the non-standard page.
-
-
- !!!!!!!! WARNING !!!!!!!!!!!!!
-
-
- Would-be web masters beware: You do NOT make a good impression on a _customer_
- when you crash their browser and/or machine!! Please put experimental and
- non-standard features (crap) on _optional_ pages.
-
-
- !!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
- Thus web authors who want the customer to be able to access their info will steer
- clear of non-standard features on the primary pages, and offer secondary or
- alternate pages for advanced features. Burying a link to a text page on a
- non-standard page does NOT work when the non-standard page crashes the customer's
- browser. So if you want your customer to see your info, you better put the
- standard pages FIRST!
-
- http
- -------------------
-
- http is the protocol that is used between the client (browser) and the server. The
- client submits requests to the server and the server satisfies them if it can.
- Most often the request is for a file, but it can also be a request to run a script
- and return the result. Thus the client is allowed to browse what the server has to
- offer.
-
- Without an http server no one can see what you have to offer. Servers should be
- available at all times so a direct fulltime Internet connection is required.
-
-
- There are three http servers for the Amiga. There is one based on the NCSA httpd
- software and it is freeware. It comes with Amosaic or is available separately at:
-
- ftp://ftp.ominpresence.com/pub/amiga/amosaic/
-
- Secondly there is AWS which is also freeware and much faster than the NCSA
- version. AWS is written by Mike Meyer and is available at:
-
- http://www.phone.net/aws/
-
-
- Thirdly, there is Aserve which is a commercial version of AWS.
-
-
- Even if you don't have a full time connection you can build and test your pages on
- your Amiga. Pages are written in plain text using HTML . You can test your pages
- using the open local option of the client (Amosaic). When they work it is simply a
- matter of finding someone with a server who will serve them for you to the WWW.
-
- MIME
- ---------------
-
- MIME -- Multipurpose Internet Mail Extensions
-
- MIME allows for attaching binary files to email messages.
-
-
- You can find out more about the MIME standard by reading RFC 1521
-
- You can use archie and look for the file /rfc/rfc1521.txt
-
-
- If your email program does not understand MIME attachments, you can use a separate
- program such as MUNPACK for the Amiga.
-
- There are also MIME tools on Aminet such as METAMAIL and MetaTool.
-
-
- Some of the email packages such as THOR support MIME, and some of the web
- browsers such as Ibrose use mime types for specifying helper applications.
-
- G02
- ---------------------
-
- What is the Internet and Usenet?
-
- Two examples of WAN's which use entirely different techniques, but whose services
- are overlapping. There are interconnections and usenet traffic can and does
- travel across the internet, but for the most part they are separate networks.
- Also the Internet is actually many networks which are interconnected on a world
- wide scale.
-
- Usenet utilizes the phone system and temporary links to move information between
- systems. It uses a system of store and forward. It stores up outgoing messages.
- Then on a periodic basis makes a connection to a specific computer and forwards
- the messages, and downloads any incoming messages then breaks the connection. A
- popular usenet protocol is UUCP and the most popular application is NEWS which
- is also now on the Internet.
-
- The Internet on the other hand is mostly a shared backbone which is always
- available between the primary systems. The usenet does not use dynamic routers.
- An Internet router is always on and always connected to other routers. An
- internet router immediately determines an incoming message's next destination and
- immediately sends it on its way. A usenet "router" waits until the next scheduled
- connection time before sending the message on its way. The most common protocol
- on the Internet is TCP-IP and one of the most popular applications is Mosaic
- which relies heavily on FTP and Gopher.
-
- G03
- ---------------------
-
- How do I connect?
-
- There are three basic ways with more to come hopefully.
-
- A) modem to modem
-
- B) modem to commercial service
-
- C) direct to WAN or ISP provider
-
- Or if the company where you work has a network, you should contact your local
- network administrator about the procedures for getting network access at your
- company.
-
- Other modes of free access are available through schools, universities, libraries,
- and government programs. Ask around your local user groups, etc.
-
- G03a
- -------------------------
-
- modem to modem
-
- This is basically the poor man's network, but it works well. Usenet uses this
- method. Since there is some overlap between usenet and the internet you can gain
- some access to the internet such as mail or news which do not require immediate
- response (i.e. messages are usually only sent once a day).
-
- To get on the Usenet you have to either know someone who is already on it and
- daisy chain from them. Or you can access a BBS which offers usenet access. User
- groups and BBS are also good places to ask for usenet access. Also you can check
- the UUCP FAQ UUCP FAQ for information.
-
- If you can get a modem connection to a machine on the internet, then you can use
- it as an intermediate host to access most of the internet by using command line
- utilities such as ftp or telnet. Because of this restriction to command line mode
- this style of connection is often referred to as a _shell account_. Since your
- machine is acting as just a terminal to the intermediate host, this type of
- connection requires a two step process to download a file to your machine. First
- you must FTP it to the intermediate host, and then you will need a file transfer
- program (such as xmodem or kermit) to transfer from the intermediate machine to
- your machine.
-
- There are several ways around the two step. For Shell accounts you can ask your
- provider about TIA or mlink which is on Aminet. Also, two recent protocols have
- evolved called SLIP and PPP which make the intermediate system transparent
- and provide full TCP/IP connectivity over a modem. In fact the intermediate
- system need be nothing more than a terminal server which supports SLIP or PPP.
- Both SLIP and PPP allow your computer to have an address so that TCP/IP
- applications can talk directly to your node. (i.e. your machine becomes a node,
- not a terminal). PPP can support other protocols than TCP/IP.
-
- Some universities and public access programs such as FREEnet offer free dial up
- shell accounts. If you can't find one of these or USEnet access, then you will
- need to try
-
-
- option B modem to commercial services, or
-
- option C direct to WAN or ISP provider.
-
- G03b
- --------------------------
-
- modem to commercial services
-
- Several commercial services such as Portal, BIX, and Compuserve now provide
- internet access to varying degrees as part of their service. and in essence have
- become ISP providers , but they offer their own services as well such as stock
- quotes or discussion groups.
-
- If you can reach one of these services via a local call, then you can use them to
- gain some access to the internet. If you can only reach them via a toll call, then
- you will want to find a local internet service provider. Once on the internet you
- can access these commercial services without running up your phone bill.
-
- As mentioned before, if you access the internet through a shell account, file
- transfer is a two step process. However, more and more commercial services are
- providing SLIP and PPP connections which eliminate the two step process by
- giving your Amiga it's own internet address. SLIP and PPP also provide full
- internet access, but some applications require more speed than an analog modem can
- provide.
-
- Since SLIP and PPP accounts cost more than shell accounts, some providers are
- allowing their shell account users to use TIA or MLINK which provide access out to
- the internet.
-
- G03c
- -------------------------
-
- direct to WAN or ISP provider
-
- WAN -- Wide Area Network
-
- ISP -- Internet Service Provider
-
- The WAN providers offer many kinds of connectivity from a normal dial up BBS to
- a full blown high speed WAN connection.
-
- Full Blown WAN
-
- ISP the Cheaper WAN
-
- WAN-shopping
-
- WAN and ISP providers
-
- Full Blown WAN
- --------------------------------------
-
- WAN -- Wide Area Network
-
- The full blown WAN connection is the FASTEST, most flexible and the most
- expensive. This type of connection is most useful for a group such as a business
- with a LAN, since this type of connection provides a router at your site.
- Generally connection speeds start at 56 Kbit/sec and go up. Contact a WAN provider
- for details.
-
- A full blown WAN connection also requires a great deal of expertise to manage. You
- must learn security, configuration, and troubleshooting techniques. Some WAN
- providers will provide these services for additional fees.
-
- The setup of a WAN connection is WELL beyond the scope of an FAQ, but there are
- numerous courses and books available if you wish to do the job yourself. Also the
- documentation that comes with the software and hardware is mandatory reading.
-
- Cheaper WAN
- --------------------------------------
-
- ISP the Cheaper WAN:
-
- ISP -- Internet Service Provider
-
- WAN -- Wide Area Network
-
-
- With this kind of connection all you have at your end is your Amiga, a modem, and
- a phone line. The ISP has all the network equipment at their site. You merely pay
- to use it.
-
- Over this connection they provide SLIP and PPP which require some networking
- knowledge on the user's part but not as much as managing a LAN. SLIP and PPP
- offer a full set of internet services, but at a lower speed. Generally you are
- limited to what speeds the local telco can provide. The fastest is currently
- ISDN but that can be expensive and has limited availability. So most ISP's
- will also offer standard analog modem connections of 14.4K or higher. For those
- on a budget and who aren't afraid of command line mode you can usually get a shell
- account from ISP pretty cheap. They may even let you use TIA or a similar utility
- at no extra charge. Shop around.
-
- Since these are normal phone lines and used on a part time dial up basis, this is
- nothing more than a fancy BBS, and thus the rates are lower. If you want a full
- time connection or ISDN speeds most ISPs can accommodate you...for a fee.
-
- The other big difference between an ISP and a WAN provider is that most ISP's do
- not own any phone lines. Most ISP's rent them from WAN's and recoup the costs by
- selling dial up access. This has lead to a new cottage industry and it pays to
- shop around for service.
-
- So how do you find an ISP? It is kind of ironic. If you have internet access, it
- is easy to find internet access. But if you don't have internet access, check the
- local papers, local BBS systems, user groups, etc. Once online you can usually
- keep abreast of what ISP's are available via a service called Yahoo which can be
- accessed via Mosaic at http://www.yahoo.com. Once connected look under the
- regional section. It goes down to the city level and if your city is listed
- chances are real good there will be a list of ISP's for your city.
-
- Got deep pockets and want full time connectivity? go to the
- Full blown WAN section.
-
- WAN-shopping
- ------------------------------------
-
- Shopping for the right level of WAN connectivity can be difficult.
-
- Shell accounts are the cheapest, but may not offer all the access you want. SLIP
- and PPP offer full two way communication, but at a slightly higher cost than shell
- accounts. Commercial accounts, such as AOL, may incur extra phone charges or put
- limits on your internet access, but do usually offer additional services not found
- on the internet. Direct connections can be fast, and with a full time direct
- connection you can host your own web sites and offer services. The down side to
- direct connection is that it is expensive.
-
-
- You have to run the cost comparisons yourself to see what level of access is right
- for you.
-
- Books on the subject:
-
- O'Reilly & Associates, Inc publishes book that offers some good ideas for doing
- cost comparisons. It is called "Connecting To The INTERNET" an O'Reilly Buyer's
- Guide.
-
- Another book to look for is "Connect your Amiga!" by Dale Larson of IAM .
-
-
- I'm sure there are other books as well. Time to head to the bookstore ;-)
-
- WAN providers
- --------------------------------------
-
- ISP and WAN providers.
-
- ISP -- Internet Service Provider
-
- WAN -- Wide Area Network
-
- WAN providers come in a variety of sizes and levels of service. Most of the really
- big WAN providers you probably already know such as MCI, Sprint, AT&T, BBN, etc.
- Some of the smaller ones came from government networks which have gone commercial.
- At least that is the way it is in the USA. Sorry I don't have any details on the
- European, Asian, or DownUnder markets.
-
-
- ISP's are a fairly new breed of WAN provider. ISP's are dependent on WAN providers
- for the "infrastructure" i.e. phone lines. ISPs merely sell a service, and provide
- the direct support to the customer. Most ISPs are local Ma and Pa shops, and can
- keep their costs low. Others are larger and provide more service. Also online
- services such as Portal and Compuserve have become ISPs. Since ISP's can be local,
- check your paper or local user group for leads.
-
- To get a fairly current list of WAN providers you can check your local bookstore.
- Most books on the Internet contain lists of WAN providers and ISPs.
-
-
- Of course, if you can gain internet access, you have lots of ways to find
- providers. With Mosaic you can go to indexes such as Yahoo or NCSA and search.
- Also, most of the major providers have URL's which are easy to guess; www.mci.com
- for example.
-
-
- Also, you can use electronic mail to get a copy of Peter Kaminski's PDIAL list.
- Send a message with "Send PDIAL" as the subject line. Send the message to
- info-deli-server@netcom.com Or you can subscribe by using "Subscribe PDIAL" as the
- subject line. You will then automatically get any updates to the list.
-
- PDIAL is also available from the news.answers FAQ archive .
-
- ISDN
- -----------
-
- ISDN -- Integrated Services Digital Network
-
- ISDN -- Ithaca Swing Dance Network (you never know what you'll learn on the web
- ;-)
-
-
- Since I don't have ISDN, please forgive any mistakes, and please do check out the
- other sources mentioned below.
-
-
- ISDN offers all digital transfer at much higer data rates than analog lines and
- modems. ISDN can also multiplex the line between several devices (you can talk to
- someone while you surf the net).
-
- ISDN lines can also handle POTS (plain old telephone service) phones. ISDN is more
- expensive than the analog POTS lines. Also, different areas of the USA have
- different ISDN rates and installation charges, if ISDN is even available at all.
-
- If you want to use ISDN to connect to an Internet provider, the provider will also
- charge a premium because they have to have ISDN connectivity also. Dialup ISDN is
- cheaper than dedicated service, of course.
-
- For connecting your computer to ISDN there are several options to consider: ISDN
- card, a Terminal Adapter, and a router.
-
-
- A router is useful for allowing you to connect multiple ethernet nodes to a single
- ISDN line. The router has an ISDN port for connecting to the line and an ethernet
- port for connecting your LAN segment. A router not only makes the connection it
- also can handle multiple protocols, perform routing decisions, perform security
- checks, and other features. There is now a wide range of models to choose from
- depending on how many and which of these routing features you really need. As you
- might of guessed, there is also a wide range of prices, too. Since ethernet cards
- are expensive for the Amiga, and if you have only one or two computers, you might
- consider the other options.
-
-
- A terminal adapter (TA) allows serial lines to be connected as well as POTS
- phones. For the Amiga you will need a serial port card, such as the MFC IV, that
- can handle the higher ISDN speeds. TA's are cheaper than routers, because they do
- not provide as many functions such as ethernet support, but for the Amiga you have
- the added expense of a high speed serial card.
-
-
- An ISDN modem card is another option and is really just a form of TA. It is not as
- flexible as a TA or a router because it is made to work with a specific computer
- (both hardware and software). For the Amiga there is the ISDN Master One problem
- for US residents is that the european cards use S interfaces and the US uses U
- interfaces. This means US residents will also need a NT-1.
-
- For more authoritative information on ISDN start with ACC's ISDN primer at
-
- http://www.acc.com/internet/technology/about/isdn.html
-
- which is a short document which explains most of the basic terminology. Then read
- the comp.dcom.isdn ISDN FAQ document which is available at the FAQ Archive
-
- !!!!!!!!!!!!!
-
- Another good ISDN FAQ I just found:
- http://www.HiWAAY.net/hiwaay/support/isdn.html
-
- !!!!!!!!!!!!!
-
- Both documents have pointers to lots of ISDN info. Or you can start like I did
- with a web search on ISDN at www.yahoo.com or similar site.
-
- G04
- --------------------
-
- What is a server?
-
- A server is a computer which acts like a library for files, and programs. It can
- also be set up to allow users to change the information as well. Several programs
- and protocols exist for creating a server: Appleshare, NFS, Xwindows, FTP, news,
- gopher, WWW, DCE, SQL, and user written applications.
-
-
- Appleshare and NFS make remote disks seem like local disks. Thus allowing a group
- of users to share disk space and information if so desired.
-
- Xwindows is a device independent network terminal package which supports a
- graphical user interface. It can be thought of as an display server. The
- application can be run on one machine and the display served to any Xwindow
- device on the network. If Excel had a X window version it could be run on a Mac
- or PC and the display could be on any Xwindow device anywhere on the network. It
- could even be displayed on an Amiga using X11R4 .
-
- FTP server software allows you offer a portion or all of your disk drive for
- remote access. Unlike Appleshare or X windows you cannot run applications
- remotely. FTP stands for File Transfer Protocol and file transfer is all that it
- does. It does provide a binary mode of transfer so that you can copy applications
- to your local hard drive or ram and then run them.
-
- News, gopher, and WWW are special servers for information which require a client
- software package to access. They can be thought of as network databases. These
- are explained in other sections. G07
-
- Database servers are usually custom written to fit a need such as inventory. SQL
- is standard query language and DCE is distributed computing environment. SQL and
- DCE can be used in vendor or user written applications to create or access
- multiple database servers. This allows the programmer to distribute the load
- across several machines. Also it allows for more seamless integration of data from
- several non-similar computer systems in a transparent manner to the user. For
- example, very few executives want to FTP to three or four machines to pull
- together the information for review. They tend to like to click on a weekly report
- button and have the program do all the work. Since SQL and DCE are standards, the
- weekly report program is somewhat shielded from hardware specifics or changes.
-
- G05
- ---------------------
-
- What is an archive?
-
- A computer site which advertises and stores a large amount of public domain and
- share ware software and documentation.
-
- G06
- ---------------------
-
- What is a mirror?
-
- Some archives are heavily used and therefore must be supported by multiple sites
- which are often located very far apart. Each site should ideally have identical
- information available therefore they are mirrors of each other. When one site gets
- a new file it must be mirrored to the other sites usually using FTP.
-
- G07
- ---------------------
-
- What are Gopher, WAIS, and WWW?
-
- Three kinds of network information servers. Each more powerful than the next, but
- with some interconnectivity. Each server requires a client application to allow
- the user to access the information. For Example, a Mosaic client can access all
- three servers. The main purpose of these client/servers is to help a user
- navigate the Internet to find information and files.
-
-
- Gopher:
-
- Gopher is a menu utility which simply uses FTP for retrieving files from archive
- sites. Gopher also uses a search utility called Veronica for aiding users in
- finding files in the gopher archive sites. Veronica can do keyword searches
- whereas Archie can only search for file names.
-
-
-
- WAIS:
-
- WAIS is Wide Area Information Server which provides information lookup services
- to libraries and databases on the Internet. A simple WAIS client allows the user
- to select databases to search from a list. The user then provides keywords to
- search for, and the WAIS client allows the user to view any matches found. This
- is cumbersome once the list of databases grows into the thousands. Screenfull
- after screenfull of database names scroll by.
-
- As of March 16, 1994 future versions of WAIS server & client library will be
- known as ZDist NOT freeWAIS. freeWAIS is based on the older version of the
- search and retrieval protocol Z39.50-1988. The newest version of that protocol
- Z39.50-1992 is NOT backwards compatible.
-
- Since both versions will be around for awhile, a name change for the server/client
- software libraries had to be established. Both freeWAIS and ZDist are maintained
- by CNIDR. Kevin Gamiel is the contact.
-
- It should be noted that the Z39.50 protocol is a standard which is NOT published
- or maintained by CNIDR, but is publicly available. Z39.50-1992 is the protocol of
- choice for many other network based information search and retrieval applications
- besides WAIS.
-
- Much more info is available thru Mosaic by searching on CNIDR, WAIS, or Z39.
-
-
-
-
- WWW:
-
-
- WWW stands for world wide web which is name used to describe the global system of
- hypertext and multimedia services. WWW consists of clients called browsers and
- servers called web servers. Web servers use http and html to make the WWW
- hypertext and multimedia services available to mosaic and AMosaic clients over
- the Internet. WAIS support is being added to Mosaic. Mosaic offers WAIS an
- effective interface and WAIS offers Mosaic an effective search engine. Other
- commercial search engines are also available.
-
- All three of these servers use the TCP/IP protocol, and all have both public
- domain and commercial versions of the clients.
-
- G08
- ---------------------
-
- What are Mosaic, html, http, and browser?
-
- Mosaic is a hypertext based multimedia interface for browsing the Internet, thus
- it is referred to as a browser. Mosaic is the name of the browser created by NCSA
- for Xwindows, Macs, and Windows. In the last year several other browsers have
- been created for the various platforms. Some are free and others are commercial.
-
- Amosaic is developed by public domain effort for the Amiga. Although it may not
- have all the toots and whistles of the other browsers, it is free! Also, it was
- started after the others and thus has to play catchup. Development of all of the
- browsers has been slowed down because they are all dependent on html and http
- which are in a state of change.
-
- The browsers are primarily used to access the thousands of World Wide Web (WWW)
- servers, but can also be used to access WAIS, Gopher, and others. They enable
- the user to click on hypertext links which will automatically use the network
- services such as FTP to retrieve the information pointed to by the link
- regardless if it is text, sound, or graphics. They utilize shareware and public
- domain viewers and players of the users choice to play the sounds or to display
- the pictures or animations. Thus the browser is a point and click front end to a
- wide array of other software.
-
- Navigating the Web can be a challenge due the enormous size, but there are
- several tools that make it easier. The simplest tool is the usage of a common
- naming convention for the main WWW servers. Most large organizations have their
- primary server named www. For example, NASA's primary server is called
- www.nasa.gov. Microsoft's server is called www.microsoft.com. Can you guess what
- NewTek's server is called ?
-
- Once you know the name of the server, it is very easy to create the URL which the
- browser needs to make the connection. URL stands for Universal Resource Locator
- which is just a scheme for specifying the type of link to make, to which host,
- and optionally which file. To open NASA's front door (primary home page) just use
- the Open URL menu option and type: http://www.nasa.gov This says make an http
- connection to www.nasa.gov. Since no file was specified it will get the default
- home page for that server.
-
- Other navigation tools include search utilities, the what's new page, and indexes
- by category or subject. Most of this is explained on line. Just go explore.
-
- G09
- --------------------
-
- What are Veronica and Archie?
-
- Archie is the older of the two search tools. A user submits a query to Archie or
- Veronica and they search their database for the location of files or programs.
- Veronica is associated with the Gopher servers.
-
- Both require TCP/IP at some point. Although both can be queried by electronic
- mail.
-
-
- There is an Archie client available for AmiTCP via anonymous FTP from
- ftp.demon.co.uk in the /pub/amiga/amitcp directory.

-
- What is news?
-
- NEWS is a global BBS run by everyone and no one. I will describe it briefly here,
- but see the NEWS FAQ for details.
-
- NEWS is made up of broad topics called news groups, to which people can post or
- respond to posts. Anyone can create a new post, but new news groups are added
- based on an email voting system. A few groups are moderated, but most are not.
- NEWS is available via usenet, the internet, and some commercial services. Almost
- NOBODY carries ALL the news groups. User access is through a news reader
- application that accesses a news server. There are many variations of news
- readers. Several for the Amiga can be found on Aminet and Fred Fish .
-
- GRn by Michael Smith is one Amiga News reader.
-
- Arn by Roland Bless (rob@spirits.ka.sub.org) is another.
-
- THOR and Offline-Orbit are offline news and message readers.
-
-
- NEWS began life on a college campus and then became the USENET news as it spread
- to other college campuses and beyond via UUCP . Today it is also carried across
- the Internet using the NNTP application over TCP/IP. The links between servers
- are set up manually by news server administrators and the links are called news
- feeds. A lot of the feeds come and go, since they are done on an informal basis.
-
-
- GRn in combination with INetUtils allows you to access news over either NNTP or
- UUCP.

-
- What is a Set top?
-
- A twinkle in some entrepreneur's eye. It will most likely occupy the __TOP__ of
- your television __SET__. Some call it Interactive TV. Some call it info-pliances.
- It could possibly bring the internet to your home via cable TV or phone lines,
- but more than likely it will only bring limited expensive services.
-
- AT&T says, "YOU WILL." I say, "I AIN'T YET." ;-)
-
- A newspaper article listed the following companies as competition for IBM in the
- set top market: General Instrument, Scientific Atlanta, 3DO, and Nintendo. NO
- mention of HP, Sony, SEGA, or <insert Amiga owner of the week here>. Hmmmmmmm.
-
-
- AS most of you know ESCOM's Amiga Technologies is hawking the Amiga as THE
- platform for making set top boxes. So we shall see. VIScorp is also very
- interested in the Amiga as a set top box.
-
-
- The race will be to develop a box and service that will sell (i.e. it has to be
- cheap and yet do a lot.)
-
- The starting gun has sounded in the States with the telecommunications bill which
- opens up the phone and cable markets.
-
-
- Several operating systems are being developed for set top boxes. Since the box has
- to be cheap, Win NT is obviously not in the running. JAVA is Sun's bid which is
- gaining a foothold in the Web market. Apple is rumored to have an OS tailored
- specificly for set top's. So keep the top of your set open ;-)
-
- xwindows
- ------------
-
- X-windows allows you have a graphical user interface similar to workbench where
- you can run programs (clients) both locally and remotely.
-
-
- A breif description of how X-windows works:
-
- X-windows involves two cooperating programs. One program acts as a server, and the
- other as a client. The client programs need not be on your machine, but the server
- program must be on your local machine. For remote clients to talk to your server
- you must be running a networking protocol either TCP-IP or DecNet. Of course if
- your clients are local, no network is required.
-
- The first step to starting X-windows is run the x-server program which isn't very
- exciting by itself. The server just opens a plain root window and starts listening
- for clients to give it commands. One of the first clients you will want to run is
- a window-manager. As the name implies it helps you manage the windows that your
- clients will open. Similar to running workbench, but it is much more limited.
-
- Once the server and a window manager are running you can begin running other
- clients which can be local or on a remote machine. You can even cut and paste data
- between clients.
-
- The benefit of x-windows is that the client programmer does not have to write a
- special user interface for each type of machine on the market. Any machine with an
- x-server should be able to accept the display from the x-client regardless of what
- kind of machine the client is running on. This also means that the client does not
- have to written to run on your machine. For example, you can use a word processor
- written for a cray from your amiga as long as the word processor supports
- x-windows and you have a cray to run the client on ;-)
-
- The downside of x-windows is that it requires a lot of bandwidth to operate. You
- can get it to work over a 14.4 baud modem, but it is slow. Even over ethernet
- graphic intensive clients can be sluggish. Also, more than one flavor of x-windows
- emerged so that the main benefit is somewhat negated. Motif is one of the main
- flavors of x-windows, but others exist.
-
-
-
- Also check out the X11 FAQ for help with X specific questions.
-
- TIA
- -------------------
-
- What is TIA and Mlink, and are they useful to an Amiga User?
-
- TIA ==> The Internet Adapter (TM)
-
- by Cyberspace Development, Inc. (CSD).
-
- marketplace.com
-
- It is a commercial software product that enables shell account users to have
- partial SLIP access to the Internet without paying the extra monthly surcharge of
- having a full SLIP account, and without having to have an Internet address. Since
- TIA runs on the service providers host, Amiga users can take advantage of it too.
-
-
- Although the service provider misses out on some revenue, they also miss out on a
- lot of management headaches from SLIP. Check with your service provider to see if
- TIA or Mlink is endorsed.
-
- The drawback to TIA is that you don't have your own internet address, and
- therefore no one can telnet or FTP to your machine. This does not stop you from
- running Mosaic or FTP *OUT*. Just the incoming is unavailable. In other words you
- can act only as a client not a server.
-
- Another drawback is that you still have to have SLIP on the Amiga side. TIA
- basically sets up a software gateway that speaks SLIP to your Amiga over the
- serial port of the host, and TCP/IP over the host's ethernet card. TIA doesn't
- allow the AmiTCP packets to pass directly to the Internet therefore your machine
- has no address as far as the Internet is concerned. The Internet only sees the
- service host. TIA makes the service host make TCP/IP requests on your behalf and
- then passes you back the results. This does not work for some TCP/IP utilities
- such as ping. Think of it as layers or stacks the data must filter through with
- TIA as a middleman or translator.
-

-
-
- There are well written docs available on line from CSD that explain TIA much
- better. You can FTP them from marketplace.com. You can also use gopher and
- Mosaic to the same site.
-
-
- Mlink is available on Aminet and performs a similar function as TIA. It allows
- you to use a cheaper shell account to access the Internet, but just like TIA it is
- a one way glass: you can see out, but no one can see in.
-
- G15_SAMBA
- ---------------
-
- What is SAMBA and is it available?
-
-
- SAMBA is a suite of programs which work together to allow clients to access Unix
- filespace and printers via the SMB (Session Message Block) protocol.
-
- In practice, this means that you can redirect disks and printers to Unix disks and
- printers from LAN Manager clients, Windows for Workgroups 3.11 clients, Windows NT
- clients and OS/2 clients. There is also a Unix client program supplied as part of
- the suie which allows Unis users to use an ftp-like interface to access filespace
- and printers on any other SMB servers.
-
-
- Summary of SAMBA suite components:
-
- smbd the SMB server. This handles actual connections from clients
- nmbd the Netbios name server, which helps clients locate servers
- smbclient the Unix-hosted client program
- smbrun a little "glue' program to help the server run external programs
- testprns a program to test server acess to printers
- testparms a program to test the SAMBA config file for corectness
- smb.conf The SAMBA config file
- smbprint a sample script to allow a Unix host to use smbclient to print
- to an SMB server
-
- Although this is the UNIX suite summary, the source code is available and SAMBA
- has been ported to the Amiga. SAMBA is of particular use to Lightwave users to
- move files between the Amiga and a PC.
-
- JAVA_VRML
- -------------
-
- What is JAVA and VRML, and are they available for the Amiga?
-
-
- JAVA is being spearheaded by SUN Microsystems,and you can check their web site for
- details.
-
-
- JAVA is a new language for the WWW that has more power than HTML . Don't expect
- it to replace HTML any time soon though. JAVA is intended to augment HTML by
- allowing web page authors to provide programs which run on the client's machine.
- These programs can be anything from an animation to a full blown user interface
- into a remote database or application. In fact there is more than one form of
- JAVA: JAVA as applets, JAVA as applications, and JAVAScript.
-
- JAVA applets run in the context of a web browser. Currently there are no Amiga web
- browsers that support JAVA applets, but that could change soon.
-
- JAVA applications require an interpreter called a virtual machine (VM).
-
- JAVAScript is more of a Basic langauage which is only supported by Netscape and
- Microsoft's Internet Explorer. It was developed by Netscape and SUN.
-
- Since JAVA is a programming language, you can find tools on the new GEEK GADGETS
- cd rom from Cronus .
-
-
-
- JAVA is being ported to the Amiga. Niall Teasdale has a web page on the project
- which is being called P'Jami.
-
-
- There are also several other ports of JAVA underway. One is called Kaffe and it
- supplies a VM to run JAVA applications. Another is the JAVA JIT compiler.
-
-
- VRML is Virtual Reality Markup Langauge which is being spearheaded by SGI. This
- language also augments HTML and allows web authors to add 3d graphics, or to build
- 3d graphics worlds (virtual reality) which can be navigated over the web or
- locally.
-
- Remember Calagari? The Amiga 3d graphics package which became Truespace when they
- ported to the PC. Well they are heavily involved with SGI in developing VRML
- tools. Even if there is no Amiga port of VRML viewers, you can still get your
- Amiga 3d graphics objects into VRML format. Lightwave has a VRML saver. Also
- there are DXF to VRML converters on other platforms.
-
-
- You can always use one of the web search engines to find tons of Java and VRML
- stuff.
-
- IRC
- ------------
-
-
-
- IRC == Internet Relay Chat
-
-
- Sort of like a conference call but instead of speaking you type. They can be
- somewhat structured with a moderator and guest which accept questions sort of like
- a call in show on TV.
-
- There are some IRC clients such as Grapevine for the Amiga on Aminet.
-
- You might also want to check out CLChat.
-
- proxy
- -----------
-
- !!!!!!!! new section !!!!!!
-
- Proxy
-
-
- Proxies are intended as a security measure for firewalls, but as Randall Lasini
- describes on his web page it can also be used to connect multiple machines to the
- internet over a single dial up line without having to get a unique internet
- address for each machine. I'll describe the basic idea here and you can get more
- info from his web page at
-
- http://www.eck.net.au/~suicyde/AmiLAN.html
-
-
- Although it is not a perfect solution, it is quite interesting. Your Internet
- Service Provider (ISP) does not have to provide an internet address for each of
- your machines, but it would still be a good idea to get your ISP's blessing in
- case there are any unforseen problems or if your ISP considers it as a different
- form of service.
-
- The solution requires httprox14 and HiJack which are both on Aminet and assumes
- you will be using an Amiga to dial into your ISP. Randall's solution was done
- using all Amigas with Arcnet cards, but it should be doable with any physical
- media that has a SANA II device driver. The solution was also performed using
- AmiTCP 4.2.
-
-
- HiJack and httprox14 are installed on the Amiga which is connecting to the ISP.
- This Amiga must also being running a TCP-IP stack which supports the Gateway
- function. AmiTCP supports the gateway function, but it must be enabled by editing
- the amitcp:db/amitcp.config file. This Amiga has now become a special kind of
- gateway called a firewall.
-
-
- Point each of your "hidden" machines to use the gateway. This is done on an
- application by application basis, and is not supported by all applications.
- Ibrowse has a preferences tool for setting a proxy gateway, but others use
- environment variables such as "setenv nntpserver gw-net.amiga.net" or "setenv
- http_proxy gw-net.amiga.net:8080" where gw-net.amiga.net is the name of your Amiga
- which is acting as a gateway.
-
- The HJprox will route your applications packets to the internet and remember where
- the returning packets go to. Currently httpprox14 will not handle "refresh" or
- random links like the one at Yahoo, but if you have an upstream proxy available
- you might be able to use the random links.
-
- As I said it isn't a perfect solution, but it looks quite interesting. Let me
- know ( and Randall!) what setups you get to work, and I'll add them to the FAQ.

-
- GHC01
- ----------------
-
- I only have two machines, an Amiga and __________.
-
- How can I exchange data without a net?
-
- Four solutions come to mind. From least to most expensive:
-
- 1) Floppies
- 2) a) NULL Modem cable (serial/modem port)
- b) Parallel cable (may require special wiring. consult software)
- 3) External SCSI or IDE
- 4) Ethernet (Ok, OK, so this one is a net.)
-
-
- 1) Floppies
-
- If the data will fit on a 720k or 1.4M floppy then you have it made. See
- appropriate section below for details on your computer setup.
-
- 2) a) NULL Modem cable
-
- If the two machines are in the same room a null modem cable is useful for moving
- larger amounts of data. You will need software in addition to the cable. You can
- write your own or use something like TwinExpress which is on Aminet . In
- addition to moving files TwinExpress will also allow you to print remotely. For
- example, If you have a postscript printer hooked to the PC's LPT2 port, then
-
- copy hd0:psfiles/mydoc.ps ~LPT2
-
- will send the postscript file over the nullmodem cable to the PC printer.
-
- b) Parallel cable
-
- If the computers are close together (6 to 12 feet), then a special parallel cable
- can be used to connect them.
-
- PARnet is available for PC's and can be made to work with the Amiga version of
- PARnet . Sorry, I don't have any details. If someone wants to send some, I'll add
- them to the FAQ.
-
- Link It! is a commercial solution that will work with either serial or parallel,
- and comes with a parallel cable.
-
- PLIP , is also a possibility but I don't have any details.
-
- Also there is a program on Aminet called PC2Amiga.
-
-
- 3) External SCSI or IDE
-
- The next cheapest solution is to get a SCSI external drive with removable media
- such as a Syquest or Bernoulli. See below for details and an example of
- sneakernet.
-
- 4) Ethernet
-
- Of course there is nothing wrong with setting up an ethernet LAN between just two
- machines other than cost.
- NFS solutions:
- Amiga -- NFSd by Interworks
- Amiga -- ch_NFS (comes with AmiTCP)
- MAC -- MacNFS by Thursby Software http://www.thursby.com
- PC -- PcNFS by Sun
-
-
-
-
- PC clone to/from Amiga
-
- --------------------------------
-
- Floppies and removable media can be formatted in MSDOS format. The Amiga can then
- read and write to them using CrossDos which is included in AmigaDOS 2.x and
- higher. CrossDos can also format a MSDOS disk, but it takes a while. To preserve
- long file names you can use LhaNT under Windows NT.
-
- For PC you can get Conversions Plus by DataViz which allows the PC to read MAC
- disks. It also provides file conversions such as Pict to tiff. Combine this with
- MaxDos on the Amiga and you can exchange data between a PC and Amiga using a Mac
- formatted disk! Now that's Mondo.
-
-
- Mac to/from Amiga
-
- --------------------------
-
- There are now commercial products which allow the Amiga to read Mac formatted
- floppies and disks (both removable and hard). MaxDos and CrossMac.
-
- Under System 7:
-
- The Mac will automatically recognize a MSDOS disk. Another trick learned from the
- Amiga. It is called PC Exchange and has a control panel for dealing with SCSI
- disks.
-
-
- Under system 6:
-
- The Mac can also read and write MSDOS format floppies using the Apple File
- Exchange utility which comes with the Mac operating system. AFE is not
- automatically installed so you may have to get off the master diskettes if you
- cannot find it on your Mac. AFE can also format a disk as MSDOS. AFE MUST BE
- RUNNING BEFORE you insert the MSDOS disk or it won't recognize it!!
-
-
-
- Lee Stranahan's Mondo-Sneakernet system:
-
- ---------------------------------------
-
- From video and back to video by way of a Mac and PC.
-
- Load digitized footage from Exabyte tape into Mac using Missing Link;
- Process in AfterEffects;
- Store sequence of PICTS on Mac EZ (removable MSDOS format) drive;
- Move cart to EZ IDE in PC;
- Load PiCTS into Perception...
-
- Of course, there are mucho other ways to skin a file.
-
- GHC02
- -----------
-
- How do I connect a thin or thick net card to a 10baset net?
-
- You need a 10baset transceiver called a TPAU (Twisted Pair Access Unit). The TPAU
- should have an RJ-45, and an AUI connection.
-
- Set the jumper on the card for thick net. Use the thick network connector called
- an AUI and connect it to the TPAU's AUI connector and then connect the TPAU's RJ45
- connector to your network. This setup requires two cables: one AUI, and one
- RJ-45.
-
- For connecting the Thin net connection to twisted pair thin net instead of a co-ax
- thin net, you will need a ballun.
-
- GHC03
- ------------------
-
- What do I need to hook up my Amiga 2,3, or 4000 to ethernet?
-
- If the following sounds like geek 8-)
-
- then try the Generic (G) section.
-
- Also you can try the book store for a variety of books on the subject including
- "Connect your Amiga!" by Dale Larson of IAM . They can go into a lot more detail
- than an FAQ.
-
- You basically have two choices: a direct connection which requires a ethernet card
- or a much slower remote connection via the serial port. An ethernet card is also
- referred to as an ethernet adapter, an ethernet controller, or as a network
- interface card. One reason it is called a network interface card is that there are
- other types of networks out there besides ethernet ( ARCNET for example).
- Ethernet is just extremely popular.
-
-
- There are several cards to choose from and they support different ethernet cable
- types. See the generic section for a description of cable types. See the product
- specs section to see which cards support which cables.
-
- In addition to the card you will need a protocol to communicate to other hosts or
- nodes. See a description of protocols in the generic section. The protocols all
- require configuration such as an address which you should get from your network
- administrator or service provider.
-
- Last but not least you will need some network applications to use over your
- network link. Telnet and FTP usually come with the TCP/IP protocol, but there are
- many others available.
-
- In summary, you will need: 1) NIC 2) Protocol 3) Application.
-
-
- Ethernet cards:
-
- The A2065 was by Commodore Business Machines.
- The A4066 is by Ameristar supersedes the A2065 card.
- The LAN Rover was by ASDG and is also called the EB920.
- The Hydra is by Hydra Systems
- The Ariadne is by Village Tronic
-
- Also cheap PC ethernet cards can be used with GG2 bus+ card from
- Software Results Enterprises .
-
- The Ariadne is a hybrid card which includes both ethernet and parallel ports on
- the same card.
-
- All of these cards are full size and most are SANA II compatible.
-
- Protocol:
-
- All these cards can be used with protocol software such as
- TCP-IP:
- AmiTCP by NSDi
- I-NET 225 by Interworks
- AmigaNOS
- AS225 was by CBM
- Other:
- TSSnet DECnet software by Thunder Ridge, Inc. ,
- Novell Netware client by Oxxi
- Amiga to Amiga:
- ENLAN-DFS
- Envoy
- DNET (also does Amiga to Unix)
- SAMBA (also does Amiga to Unix or PC)
-
- Resource Management Force
- has a zorro II card called QuickNet which uses
- thin ethernet, and special Amiga to Amiga software.
-
- Serial port:
-
- The serial port offers a much slower, but much cheaper way to build a network. By
- using a high speed modem connection to an Internet Service Provider you can use
- your Amiga serial port to become a full fledge node on the Internet. The internet
- requires the TCP-IP protocol and you will need either SLIP or PPP to drive
- the serial port. SLIP comes with AmiTCP and PPP.device is available on Aminet.
-
- If you plan on tying several machines to the internet over a single SLIP or PPP
- line, you will HAVE to coordinate it with your service provider, otherwise only
- one machine will be seen. Unless of course you are clever like Randall Lasini and
- figure out a way around it.
-
- Other types of networks can also be supported via the serial port such as DECnet .
- Again the tradeoff being giving up speed for distance and cost.
-
- No place to dial into? You can usually find a book on the Internet at a bookstore
- that lists the major providers, but your local user groups and BBS users can
- provide good insight into which are the best or cheapest.
-
- GHC04
- ----------------
-
- Can I hook up an Amiga 500,1000, 1200 to ethernet?
-
- Yes, Almost all Amiga models can be hooked to the ethernet. Using the serial port
- is the cheapest, but the fastest is a direct connect using an ethernet adapter
- card.
-
- For the 1200 Interworks has an ethernet card called ICard that will support
- the major protocols. They also have some Amiga peer to peer software products for
- the ICard.
-
- For the 500 and 1000:
-
- The A2065 has reportedly been used successfully with third-party expansion
- boxes, such as Bodega Bay. It has also been reported that the A2065 card can be
- used with the Slingshot expansion device used with an Amiga 500 and a SupraDrive
- 500XP's pass-through.
-
- The A2065 has been superseded by the Ameristar A4066 . Don't know if it
- works with the A500 or A1000 expansion buses.
-
- The serial port approach for TCP/IP is supported by:
-
- several flavors of AmigaNOS
- AmiTCP
- I-Net 225
- Miami
- TermiteTCP
-
-
- all of which require SLIP or PPP to use the serial port. DECnet and DNET
- can be also be used with the serial port.
-
- GHC05
- ------------------
-
- Arcnet runs at about 2.5 Mbits/sec which is a lot faster than parnet or Appletalk,
- but not as fast as ethernet. Arcnet hardware is cheaper than ethernet, however, so
- for a small shop they may be a better deal.
-
-
- Once upon a time, CBM released the A2060 for the Amiga 2000, and the A560 for the
- A500. You can probably still find these used, and apparently there is a SANA II
- driver for them called ch2060.device by Carsten Heyl. Look on Aminet.
-
-
- CSA was working on some, but are on hold pending the outcome of the CBM
- liquidation. Contact CSA if you are interested.
-
- GHC06_ISDN
- ----------
-
- Can I hook an Amiga to ISDN?
-
- Yes, ISDN Master is one solution for hooking an Amiga to ISDN .
-
- Since I haven't done this myself, I'm interested in hearing from those who have
- as to what solutions are available and what specifically is required.
-
- GSC01
- -----------------
-
- What terminal emulations are available over ethernet?
-
- The AS225 package allows rlogin using the Amiga console (a termcap is supplied)
- only. A separate rloginVT program is supplied for VT100 emulation. Under X
- Windows, xterm provides terminal emulation that typically works with all software
- available on the host.
-
- AS225r2 provides telnet and nterm (telnet with VT100).
-
- TSSnet DECnet provides VT100 terminal emulation using the DECnet CTERM
- facility or use your favorite VT compatible Amiga terminal program including
- VLT.
-
- VLT works with TSSnet DECnet, Enlan, and with tn3270.device for AS225r2 . VLT
- provides Tektronix and DEC terminal emulation.
-
- telser opens the door to user your favorite modem software's terminal emulator
- with telnet.
-
- GSC02
- ------------------
-
- Can I use multiple protocol stacks on my Amiga at the same time?
- If all desired protocol stacks support the SANA II standard, several
- protocols can be run simultaneously on the same A2065 card. Some commercially
- available versions of the network protocol stacks support the SANA II
- specification now. But if they don't, you can have multiple hardware interfaces to
- run different protocols on the same machine simultaneously (i.e. one A2065 used
- for TCP/IP and one used for Netware).
-

- How can I uudecode messages from binary newsgroups?
-
- MASSDECODE is an ARexx script by Gregg Giles which will scan all newsgroups for
- uuencoded binaries, joins the parts of a single binary, and decodes the binary.
- Ideal for those who want to have binary newsgroups decoded automatically and have
- the resulting binaries put online for their users to download and/or access.
-
- It is available from Aminet as comm/news/MassDecode1.1.lha
-
- Or you can use MunPack if the file is MIME encoded.

-
- Adding to the PATH doesn't seem to work from the Shell, why?
-
-
- Each shell has it's own copy of the workbench PATH structure. This allows each
- shell to be customized, but does lead to confusion because adding to the PATH in
- one shell does not affect the other shells. To change the PATH for the workbench
- and thus all new Shells you must use the NEWPATH option of the LOADWB command. For
- example, to add work:newdir to the PATH system wide you'd type:
-
- >PATH work:newdir add
- >LOADWB NEWPATH
-
- Now work:newdir will be added to the search path system wide.

-
- Are there any peer-peer network packages for the Amiga?
-
- Yes, several.
-
- ENLAN-DFS from Interworks provides peer to peer networking and Distributed
- File System over SANA II compatible hardware.
-
- Envoy from IAM provides peer to peer networking for Amigas that is tied very
- close to the operating system. It too is SANA II compatible.
-
- Resource Management Force has a zorro II card called QuickNet which uses thin
- ethernet, and special Amiga to Amiga software.
-
-
- ALAN-FS is a peer-to-peer network package that allows full transparent
- file-sharing, device sharing over ethernet. It requires WB2.0 and the Commodore
- AS225 package. It is available from GfxBase, Inc , or
- Canadian Prototype Replicas . NOTE: Current Product status unknown. FEEDBACK
- appreciated.
-
- Dnet --- Dnet has client/server software for both Amiga-Amiga and Amiga-UNIX
- networking over a serial line. Among other things Dnet supports shells, file
- transfer, IRC, and something like NFS. Dnet is available on Aminet .
-
-
- PARnet/PARbench --- PARbench is a workbench installable version of PARnet which
- allows two Amigas to be networked using a parallel port and cable. It is basically
- file sharing similar to NFS, but Amiga only. PARbench greatly simplifies
- installing and using PARnet.
-
- GSC06
- ----------------
-
- What electronic mail options are available?
-
- The DECnet package from Thunder Ridge, Inc. supports VMSmail. AmigaELM
- supports UUCP mail.
-
- Both packages require a mail utility on a remote host.
-
- You should also pick up a copy of InetUtils from Aminet. InetUtils allows AmigaELM
- and other mail utilities to use SMTP instead of relying on a remote host.
-
- Graham Walter has uploaded a SMTP daemon for AmiTCP to Aminet
-
- Also available for both AmigaNOS flavors is a mail agent called BM, B-Dale's
- Messy-Dos Mailer. It doesn't have as nice an interface as Elm, but is easy to
- use and can build RFC822 formatted files.
-
- GMail is available as part of INET225 .
-
- VooDoo is available on Aminet. It provides a graphical user interface (GUI) but
- requires WB3.0 or higher.
-
-
- To handle MIME attachments you might also want to pick up a copy of MUNPACK
- or MetaMail.
-
- GSC07
- ----------------
-
- Is network based multimedia available?
-
- InfoChannel is a SCALA, Inc. product that can run over LAN's or modems. It
- allows remote Amiga multimedia stations to be controlled from a central Amiga
- host. Data can also be stored centrally and supplied upon demand. InfoChannel
- also comes with tools and graphics for creating a multimedia service such as a
- kiosk.
-
- Also Amosaic can be used as a multimedia hypertext user interface for both
- local and remote data.
-
-
- Also JAVA can be used as multimedia development tool. JAVA is being developed by
- Sun Microsystems, but an Amiga port is in the works by someone other than Sun.
-
- GSC08
- ---------------------
-
- Is network parallel programming available?
-
- TorqueWare (TM) is by AugmenTek and allows parallel programming between
- several Amigas. Also an Amiga running AugmenTek's TorqueWare can act as a client
- to a SGI or Mac running TorqueWare by Torque Systems.

- ---------------------------------------
-
- Questions about Commodore's TCPIP software
-
- B01 I can't login to my Amiga over the network. Why?
-
- B02 When I FTP to some hosts, I get part of an introductory
- message and then either the network hangs up or
- the connection gets closed. Why?
-
- B03 Is Domain Name Resolution available with the AS225 software?
-
- B04 Can I use NFS to mount a partition on my Amiga from a remote
- machine?
-
- B05 I can't use FTP, rsh or rcp into my Amiga. Why?
-
- B06 FTP into my Amiga works, but rsh and rcp into my Amiga don't.
-
- B07 I can communicate with machines on my network/floor/building,
- but I can't communicate with other machines even though they
- are in my inet:db/hosts file.
-
- B01
- --------------------
-
- I can't login to my Amiga over the network. Why?
-
- The AS225 software does not support interactive remote logins to the Amiga. It
- does have servers for rsh (remote shell), rcp (remote copy) and does support
- remote FTP logins. rsh allows you to execute commands on the Amiga, but does not
- allow an interactive shell.
-
- I-NET 225 has numerous servers including telnetd.
-
- For AmiTCP there are two utilities on Aminet called tnserv.lha and
- FtpDaemon.lha that provide remote telnet and FTP to an Amiga.
-
- B02
- -------------------
-
- When I FTP to some hosts, I get part of an introductory message and then either
- the network hangs up or the connection gets closed. Why?
-
- There apparently is a bug in the AS225 software that causes trouble when ftp'ing
- to a system that has a long login message. You can suppress this login message on
- some systems by typing a hyphen ('-') as the first character in your password.
-
- B03
- -------------------
-
- Is Domain Name Resolution available with the AS225 software?
-
-
- For AS225r1: No. You must have an entry in the host table for each machine you
- wish to reference by name (as opposed to IP address). Also the gateways file is
- not currently used.
-
- For As225r2: Yes. All variants support DNS, and gateway. These functions are
- turned off and on via the config files and the ConfigINet utility.
-
- B04
- --------------------
-
- Can I use NFS to mount a partition on my Amiga from a remote machine?
-
- For AS225r1: No. Currently, the AS225 software only supports NFS as a client. An
- NFS server is not included.
-
- For AS225r2: Yes. NFSd the NFS server is included. The 'd' stands for daemon which
- is a term used by the un*x community for a program which runs continuously and
- watches for certain events, and then loads the appropriate program to handle a
- given event.
-
- Not all variants of AS225r2 contain the NFSd.
-
- B05
- ------------------
-
- I can't use FTP, rsh or rcp into my Amiga. Why?
-
- Make sure that you are running inet:s/start-inet with the servers keyword (i.e.,
- "execute inet:s/start-inet servers").
-
- B06
- --------------------
-
- FTP into my Amiga works, but rsh and rcp into my Amiga don't.
-
-
- Make sure that you have an entry in inet:db/passwd for the user who is rshing
- into the Amiga (you can use the -l option to change the user trying to do the
- remote access.) Make sure that you have an entry in inet:db/hosts.equiv for the
- machine being rsh'd from.
-
- B07
- -------------------
-
- I can communicate with machines on my network/floor/building, but I can't
- communicate with other machines even though they are in my inet:db/hosts file.
-
-
- Make sure that you have routes set up to other networks. Many networks have one
- primary gateway which you should make your default route for reaching all other
- networks. See the commented-out "route add default" line in inet:s/start-inet.
-
- Envoy (E)
- ---------------------------------------
-
- Questions about Envoy
-
- E1 How do I configure a machine which has both an Amiga Link
- and an ethernet connection so that machines on either network
- can see each other?
-
- E1
- -----------------
-
- How do I configure a machine which has both an Amiga Link and an ethernet
- connection so that machines on either network can see each other?
-
- Given machines A, B, and C with node B having both Amiga Link and Ethernet card
- (Quicknet) as shown below, and all running Envoy.
-
-
- A <=== Alink ===> B <=== Ethernet ===> C
-
- In order for node A to access node C or vice versa use the following configuration
- scheme: (IP addresses for example only!)
-
-
- node A node B node C
-
- IP-Address: 244.1.a.a 244.1.b1.b1 244.1.c.c
-
- 244.2.b2.b2
-
- Subnet Mask: 255.255.0.0 255.255.0.0 255.255.0.0
-
- 255.255.0.0
-
- Use Realm: yes yes yes
-
- Realm-Serv: NO yes yes
-
- Realm-Name: NET NET NET
-
- Serv-Addr: 244.1.b1.b1 244.1.b1.b1 244.2.b2.b2
-
- Def GateWay: 244.1.b1.b1 ------ 244.2.b2.b2
-
- Loc Realms: ------ NET 244.1.0.0 -------
-
- Loc Realms: NET 244.2.0.0
-
- Rem Realms: ------ ------ ------
-
-
- where b1.b1, and a.a are the AmigaLink hardware addresses. i.e. the last two bytes
- of the IP address MUST match the hardware address on the AmigaLink interfaces.
-
- On the ethernet interfaces, however, b2.b2 and c.c can be anything since Envoy
- supports ARP on ethernet.
-
- NOTE: the IP addresses are for example ONLY! Unless you manage all the nodes
- concerned you must coordinate the IP addresses with your network administrator or
- provider.
-
- This example basically creates two TCP/IP domains: 244.1 and 244.2 Each domain can
- have multiple nodes. Node B serves as the gateway between the two domains. If you
- were to set up additional gateways to other domains, you would use the route
- command on each node that you wished to enable communications to the new domain.
- The route command merely tells TCP/IP which gateway or router to use for data
- that is to be sent to a particular domain thus providing a more direct path, and
- avoiding sending unnecessary traffic to other parts of the network.
-
- The gateway provides access to other parts of a network that would not otherwise
- be directly accessible. A router is dedicated to keeping track of routes to
- various domains. On large networks your default gateway will often point to a
- router thus negating the need to maintain route commands on each node.
-
- For further discussion of domains and beginner info on the Internet you should
- refer to ZEN

- below)
-
- * For modem connections: SLIP (included with AmiTCP) or PPP
-
- * INetUtils (optional adds SMTP, etc.)
-
- * FTPd (optional allows inbound FTP)
-
- * The following utilities are used by default by Amosaic, but you can
- use others: amisox, edplay, zgif, ams
- They are available via Amosaic once you get it up and going.
-
-
- Summary of TCP-IP software solutions:
-
- Two new entries are TermiteTCP and Miami . Both stacks are designed with "ease
- of use" in mind, and are primarily targeted at the home user who is dialing up an
- ISP by modem to connect to the internet.
-
- INet-225 is a new product from Interworks which will provide full TCP/IP
- connectivity plus includes several other useful applications.
