1. Systems that only have one drive should have the Installation disc inserted into that drive but the user should be prepared to swap the System and Installation discs around during the Installation process This is a particularly tedious process and you might prefer to use the RAM Disk to copy all the AMIGANET System Files to your SYS disc 4 Double click on the AMIGANET disc Icon A Workbench window will appear on the screen 5 For Hard and dual drive Systems locate the Install Icon in the new Workbench window and double click on it For single drive Systems double click on the Install Single Icon instead SECTION TWO 6 The installation process will now start copying Files from the AMIGANET disc to your System disc You should expect the following Files plus other Files depending on Rev level to be copied from your Installation disc to directories on the System discs DIRECTORY DESCRIPTION DEVS ANET services STARTNET REMOTEMOUNT TIME CHAT WHO amiganet device AFS server AFS handler anet dateserver anet services anscreen server anscreen ANET mountfiles SPL ANET blibs RHO TUBE LexLib CommonLib AnotherLib When the process is complete screen you may need to clear and reload the window from the SYS disc Icon Activates your computer on the Net Used to access other computers disc drives or other facilities Sets current date and time from th2. ADDRESS ALI Example 1 who Finds the current status of all the sites in the file anet addresses Example 2 who fred Finds out if there is an alias fred on the Net and if so returns the Ethernet address of fred Example 3 who fred all As above plus returns all services available at that site Description This command returns current status information about computers users on the Network and the services that are available at those sites The enquiry is made based on parameters read from the local File anet addresses This File must therefore be constructed at least once to contain all user addresses and aliases and be kept up to date It could be maintained on a central disc and down loaded periodically to ensure that all users have consistent information If the local copy is altered after STARTNET for example via a down load changes will not be valid until a re boot The information returned by WHO is in the following format lt address gt alias1 alias2 alias3 service service The at the start of the line denotes that the site is on line Command CHAT Template ADDRESS This argument is required Example 1 chat SALES Talks to the computer operated by the user with the alias SALES Example 2 chat AE4742000023 Talk to site as number No quotes Description This command instructs the service anscreen at the target site opening a small window at that site Text entered locally will be passed

6. Remote File System from the Workbench If you do copy the info File remember to set its default tool to C REMOTEMOUNT via the Workbench info command You can alter the mountfile with any standard ASCII editor that you may be familiar with such as ED Once you have edited the File to your satisfaction you can then use the CLI command REMOTEMOUNT to mount the Remote disc on your System For instance if the mountfile is called sales you would issue the command REMOTEMOUNT SALES It is not absolutely necessary to add a colon at the end of the name When the Remote disc has been mounted you can access it in the same fashion as a disc drive directly connected to your System That is to say all the standard CLI commands LIST COPY RENAME CD ASSIGN and so on will operate correctly on it For instance after using the command REMOTEMOUNT JAY where JAY is a mountfile in ANET mountfiles you can copy the File MYFILE from your current directory to JAY by typing COPY MYFILE TO JAY MYFILE You may use a Remote directory as the default path to run programs from by typing for example ASSIGN C JAY C The CLI then looks in the C directory of JAY whenever you type a command if it finds the command there it executes it Accessing Remote Discs via the Workbench If you intend to access Remote File Systems via the Workbench the following approach to creating new mountfiles ca
7. backup of the original Workbench disc that came with your Amiga and of the environment that you normally use The actual INSTALL program you should use for a particular computer depends on the number and type of disc drives attached to that machine To install the AMIGANET software perform the following steps 1 Boot the Amiga System using a COPY of Workbench or a COPY of your favourite Amiga working environment 2 Make sure that you have enough room on your System disc for the AMIGANET Files to be installed You will require at least 320 disc blocks 160 kilobytes of space for the Rev 1 4 Software as shipped The installation can be be tailored subsequently by deletion of any unnecessary services and this will reduce the space requirement To check whether you have enough space on the disc select the System Boot Disc Icon with a single click of the mouse and then choose the info option from the Workbench menu The box labeled Number free details the number of free disc blocks If this is less than 320 you must delete some Files from your System disc For instance if you have any drawers containing PC emulation related Files and you don t have a PC card in your Amiga then these items will be suitable for deletion 3 For Hard Disc Systems insert the Installation disc in any floppy drive say DF1 Dual drive Systems should have the Installation disc inserted in drive DF1 leaving the System disc in drive DFO
8. boot your computer NOTE that you must add this command after the STARTNET command Users should also note that computers with synchronised clocks will complete Workbench activity with Remote Files more quickly This effect is less significant when the Fast Filing System is used 13 SECTION THREE C Sharing Files and resources Via The Network Users on the Network can be allowed access to the disc drives of other computers as if the discs were connected to their own computer To access another Site s disc drive you must first mount it on your Amiga This can be done from the Workbench or from the CLI to mount a disc you must first modify a File in the ANET mountfiles directory This File will define the Networked disc that you wish to access Mountfile Contents An example mountfile is provided called RHO Remote Hard disc 0 This was placed in the ANET mountfiles directory during the Software Installation process and you should duplicate and modify this File to create your own specific mountfile The format of the File is similar to an entry in the standard AmigaDOS mountlist and is as follows Handler L afs handler Resident StackSize 1000 GlobVec 0 Priority 5 Startup 2 serialnumber AFS Startup SYS When you edit this example File to suit your own requirements for disc access you need only alter the last two Startup lines DO NOT alter the lines above these two The first Startu

13. the File AFS from the Site s services directory This also releases about 25k of memory To prevent users talking to you via the CHAT facility at your computer you should disable the screen service The service File for CHAT is called anscreen If a Site providing the date and time service has a problem with its clock for example when its batteries are discharged you can disable the service by deleting the File andate NOTE if the Network is already active STARTed at the Site in question the service s disablement will not be effective until the computer is re booted TIL SECTION THREE A USING AMIGANET This chapter details the Operating Modes of the AMIGANET System In particular it covers the following topics Starting up and running the Network Using the Network services Sharing Files via the Network Printing on the Network printers Talking to other users on the Network Listing current users of the Network INTRODUCTION TO AMIGANET O S The AMIGANET Operating System software provides a sophisticated interface between the Network hardware and the AmigaOOS Operating System There are various elements of this interface and it is worth understanding some of the functions At the lowest level the amiganet device provides a normal Amiga device interface to the Network Board This is a very low level interface providing primary physical movement of Data in blocks The Data arriving via
14. the Network at a particular computer consists mainly of messages for different processes within the machine These must be carefully routed for use within the File System and passed onto the correct process For this reason user programs should never read or write to the amiganet device but instead communicate with the Network via the AMIGANET System libraries Any computer which is capable of providing a service to other computers on the Network will be running a copy of the Network Services task This task is responsible for accepting service requests from Network users When a request appears that matches a service name given in the ANET services directory the Net Services task starts up a new task which will handle the service requested Commonly used services remain resident in memory as long as the Amiga is powered once they are started for the first time and the Net services task keeps track of where these tasks are There are a number of services supplied as standard with AMIGANET Among these are the date and time service the screen communications service and the AMIGANET File System AFS These services and the way in which they are used are described in later sections of this manual You may have other services installed on your Network such as a Print Spooler or TCP IP support which will have their own documentation AMIGANET has been designed to cope with problems such as discomection of the Network cabling If this

31. redibly fast but not very practical SECTION ONE AMIGANET 500 The installation procedure for an A500 Network Board is somewhat simpler just place the unit on the left of the A500 and wait for them to mate This normally takes place under conditions of darkness if you are in a hurry you can help the process along by pushing them gently together making sure that plug and edgeconn are aligned WIRES When all the Network Boards are installed either connect the computers to each other with the supplied Cheapernet BNC cables using the BNC socket s protruding from the rear of each machine or attach an Ethernet Transceiver Drop Cable between each Board s 15 pin D type connector and its respective MAU Media Access Unit IF YOU USE CHEAPERNET YOU MUST PLUG IN A 50 OHM TERMINATOR AT EACH END OF THE CABLE SYSTEM TOTAL TWO PER SYSTEM THIS IS NOT DISCRETIONARY These terminators are supplied with your AMIGANET Boards If the Network Board has two BNC sockets fitted they are connected in parallel and you may daisy chain the Sites by connecting one cable in and one cable out If there is only one socket fitted you must use a BNC T connector which plugs onto the Network Board and which provides two sockets for cable connection Even if there are two sockets on the Board some discretion must be used concerning the method of attachment using daisy chaining there might be some disruption to Network activity if it

34. sm which makes it impossible to overload an AMIGANET Site that is denied convenient DMA access however this will lower throughput capacity and therefore operating speed For other implementations of Operating Systems using AMIGANET Boards such as TCP IP flow control may not be used which makes the slot issue more sensitive An easy way to summarise these factors is this Put the AMIGANET Board in the slot nearest to the disk drives SECTION TWO INSTALLING THE SOFTWARE In order to use AMIGANET you must first install the Network Driver and Fileserver Software the first step is to install the Driver programs and their associated Data Files at every machine on your Network the second is to install the date and time services on some machines and File or other servers where appropriate The AMIGANET Software includes a number of Data and Code Files which must be installed in standard directories on your System disc The AMIGANET Installation disc contains a program that will copy the relevant Files into these directories automatically The Installation process will create a new directory called SYS ANET on your System disc If you need to have a different name for this directory install the System by hand and add an ASSIGN command to your S startup sequence File such as ASSIGN ANET different directory Most users will not need to do this CAUTION If you are installing AMIGANET onto a floppy disc machine make sure that you have a
35. ust place this entry after the line containing the STARTNET command Once you have added this line your Amiga will automatically send all printer output over the Network to the Remote printer Once SPL has been mounted all output to PRT will print on the Remote printer that you have specified in the mountfile For instance the commands TYPE report TO PRT prints the contents of the File report on the Remote printer Alternatively you can specify the SPL device directly as in TYPE report TO SPL to achieve the same effect If you subsequently wish to add and use a local printer at your Amiga you should use CMD to un direct PRT output 17 SECTION THREE D SECTION THREE E A simpler way of adding a local printer but a less efficient one would be to alter the first startup line to include your own Site s Network serial number The inefficiency here results from sending your printer output around the AMIGANET Operating System and back to yourself rather than sending it directly to your local printer For instance if your Network serial number is AE4742002C41 and the printer is connected to the serial port on your Amiga the startup lines should read as follows AK4 742002C41 AFS SER startup startup SECTION THREE E Listing Other Users on the Network To obtain a list of other users currently using the Network use the CLI command WHO This will provide information on the Ethernet Site address and
