-
- One such package is "A Remote Network Server for Appletalk" (ARNS),
- developed and available from the University of Melborne (Australia).
-
- I've attached some of the documentation provided with the client
- software they provide.
-
- At this time, the software appears to be stable and functioning well.

- ARNS
- A Remote Network Server
- for AppleTalk
-
- The University of Melbourne
- djh@munnari.OZ.AU
- January, 1992
-
-
- ARNS remote clients are currently:
-
- 1. Asynchronous AppleTalk for UNIX, version 2.0
- 2. UDPRemote AppleTalk, version 1.0
- 3. IPRemote AppleTalk, version 1.0
-
- All of which are 'adev's (clients of the 'Network' Control Panel device).
- To install the adevs, copy them to the System Folder ('Extensions' under
- System 7.0) and ensure that the 'Network' cdev is installed from an Apple
- Network Products Installation disk (see "OTHER PROBLEMS" below).
-
- The "UDP Remote A/Talk" adev uses MacTCP to communicate via UDP/IP with the
- ARNS server (IE: AppleTalk services are available from any EtherNet connected
- Macintosh that has IP connectivity to the ARNS server). MacTCP 1.1 or greater
- is required. To change the ARNS server host, hold the shift key down when the
- UDPRemote ICON is selected from the Network cdev (which happens automatically
- if no host is already set). Enter an ARNS server hostname and password into
- the dialog box. Select "Connect", and open the Chooser.
-
- In addition, the "IP Remote A/Talk" adev file is capable of switching the
- link to TCP upon request or if it determines that the link delay is greater
- than ~200ms (the ARNS server host must have 'arnsrd' installed). If the ARNS
- server uses the '-p' option, "IP Remote A/Talk" allows a connection to be
- made with a server host user name and user password.
-
- The "Async AppleTalk2" adev connects to a UNIX host via a serial line. To
- connect to the AppleTalk network, compile async.c and install it on a UNIX
- host. Select the Async ICON from the Network cdev, use the dialog box to set
- the session parameters (NB: the parity, stop and data bits affect the login
- session only, the link must be 8-bit clean to support an async appletalk
- connection). After selecting "Connect", use the async login window to login
- to the UNIX host and run async with the name of the ARNS server host as an
- argument (see the ARNS README file for more details). Open the Chooser.
-
- Under System 6.0, opening the Chooser starts the async appletalk connection
- process; there will be some delay as the address is negotiated and the zone
- list read. If MacTCP is installed and set to obtain an address from a network
- server then this process also occurs at this point. Under System 7.0 or with
- later versions of the Network Control Panel device, the connection process
- starts immediately after the async appletalk login window is closed.
-
- Protocol Timeouts:
-
- The adevs contain code to adjust protocol timeouts for NBP, ATP and ASP.
- Timeouts for ADSP are not yet supported. Additionally, the async appletalk
- adev adjusts MacTCP over async command timeouts for use with Eudora, XferIt
- and BYU/NCSA Telnet/FTP etc. Users of QuickMail need to install and use the
- QuickMail timeout thingy. Timeouts are adjusted appropriately for delays
- involved in connecting via satellite links.
-
-
- ASYNC BETA RESTRICTIONS:
-
- Speeds above 9600 have not been exercised, 38400 will almost certainly fail
- (the "Use Standard Serial Drivers" checkbox is intended to handle high speeds).
- Similarly, use of the Printer Port with the standard drivers is dubious.
- Async connections at boot time will fail on a Mac Plus running System 6.N,
- use System 7.0 :-(
-
- ** async.c does not yet support the original connection methods via UAB or
- Multigate/FastPath/atalkad. The async adev does not yet support the original
- AsyncTerm DA, a new version is in progress.
-
- UDPREMOTE BETA RESTRICTIONS:
-
- TCP links to arnsrd are not yet supported.
- Server passwords are not disguised in the dialog box text field.
- Naturally, MacTCP ***MUST*** be configured to use EtherNet directly.
-
- IPREMOTE BETA RESTRICTIONS:
-
- Naturally, MacTCP ***MUST*** be configured to use EtherNet directly.
-
-
- OTHER PROBLEMS:
-
- The Network Control Panel is a continuing source of angst. It is strongly
- recommended that version 2.0 be used with System 6.0 macs and 2.3.2 or
- later under System 7.0. Recent versions of the Network Control Panel are
- prone to crash when used with System 6.0, particularly on machines that
- don't normally have alternate network connections, IE: Plus, Classic and SE.
-
- Under MultiFinder, it is possible for a memory shortage to cause low end
- Macs to freeze. If this is a problem, use Finder for async connections.
- Other memory problems can be avoided by copying the file SHeap to the
- System Folder and rebooting. SHeap reserves sufficient memory in the
- System Heap for the Async or IPRemote connection to be opened later.
