o When Open Transport is installed, the Network control panel is replaced
the AppleTalk configuration utility program. The MacTCP control panel is
replaced by the TCP/IP configuration utility program. Both AppleTalk and
TCP/IP are located in the Control Panels folder. For simplicity and
consistency, user documentation generally refers to AppleTalk and TCP/IP
"control panels" even though technically they are utility programs.

o For Customers with the Power Macintosh 9500, 8500, 7500 or 7200
Apple Recommends you install the following updates to System 7.5.2. See
Read Me that accompanies each patch for additional details. These updates

7. On the Power Macintosh 9500, 8500, 7500, 7200 computers you will need
reinstall networking software using either the Open Transport 1.0.8
or the System Software that came on your system CD. If you use the system
software that came with your system, perform a custom install of the

Network Interface Options

Open Transport 1.1b16 supports PCI bus, NuBus, communications slot, and
PC-card network interface cards as well as built-in LocalTalk and ethernet
network adapters. For Macintosh models without expansion options, Open
Transport 1.1b16 supports SCSI-attached network adapters.

Third party network interface options available for Open Transport include
fast ethernet, ATM, and FDDI.


Open Transport is compatible with:
o existing applications that use AppleTalk as specified by Apple Computer,
o existing applications that use MacTCP as specified by Apple Computer,
o existing devices (such as printers) that you select in the Chooser
o existing NuBus network interface cards

Open Transport is compatible with existing AppleTalk, TCP/IP LocalTalk and
ethernet networks. Macintosh computers running Open Transport can be
added to
an existing network without upgrading other computers on the network.

Dial-up Network Connectivity

For connectivity to AppleTalk networks, Open Transport supports Apple
Access version 2.0.1 or later.

For dial-up connectivity to TCP/IP networks, including the Internet, Open
Transport supports third party MacTCP software extensions known as Link
Modules, or "mdevs." Serial Line Interface Protocol (SLIP) and Point to
Protocol (PPP) connectivity are provided through mdevs.

With the appropriate mdev installed, you use either SLIP (Serial Line
Interface Protocol) or PPP (Point to Point Protocol) to connect to
Service Providers and other dial-up IP-access points. However, not all
versions of all mdevs are supported by Open Transport 1.1b16. For best
results, be sure to use the versions of software recommended below.

Open Transport 1.1b16 recognizes and is compatible with the following
mdevs. When installed on your system, they are available in the "Connect
pop-up menu in the TCP/IP control panel:

o FreePPP - version 1.0.4 or later
o MacPPP - version 2.1.4 SD or later (version 2.2.0 is not recommended).
o InterPPP - version 1.2.9 or later
o InterPPP II - version 1.1 or later
o InterSLIP - version 1.0.1 or later
o MacSLIP - version 3.0.2 or later
o VersaTerm SLIP - version 1.1.4 or later
o Sonic PPP - version 1.0.2 or later
o AOL Link - the most current version is recommended

In addition, there are a number of third party PPP mdevs (including Pacer
FCR PPP and Tribe PPP) which have a common technology base and as a
result are
indistinguishable from one another to Open Transport. When installed,
appear in the "Connect Via:" pop-up menu in the TCP/IP control panel as
"TCP/IP PPP." Other 3rd Party PPP packages which share this technology
will also appear as "TCP/IP PPP." in the "Connect Via:" pop-up menu.

Obtaining Connectivity Software

FreePPP is shareware and can be found on a variety of Internet sites;
typically at "info-mac" mirror sites in the comm/tcp/conn directory. A
list of
info-mac mirror sites can currently be found at:

Some sites where FreePPP can be found currently include:

MacPPP and FreePPP

If you experience problems using MacPPP or FreePPP when Virtual Memory is
turned on, try turning off Virtual Memory. To find out how to turn off
Memory, see the topic "How do I use hard disk space as memory" in
Guide, available from the Guide (question mark) menu. Macintosh Guide is
available in Mac OS version 7.5 and later.

Upgrading SLIP and PPP Configurations

When installing Open Transport on computer set up to use PPP or SLIP with
MacTCP, Open Transport is automatically set up to configure via a BootP
over the PPP or SLIP connection. Depending on your Internet Service
this may not be appropriate for you.

If you experience connection difficulties using PPP or SLIP after
Open Transport, follow these steps:
1. Open the TCP/IP control panel.
2. Choose "Using PPP Server" or "Using SLIP" from the "Configure" popup
3. Close the TCP/IP control panel.
A dialog box appears asking if you want to save the changes in your
4. Click Save.
5. Try connecting again.

Changes to AppleTalk for Open Transport

The info button available in advanced mode now displays the hardware
of built-in ethernet.

The AppleTalk radio buttons in the Chooser are now synchronized with the
on/off option in the AppleTalk control panel.

Compatibility has been improved with Shiva Net Manager version 3.5.

The "zone Hopping" problem is fixed. (On some extended AppleTalk Phase 2
networks where a segment was configured with multiple zones, a Macintosh
sometimes change to the default zone from the selected zone.)

Wildcard NBP lookups (for example, when using a program like Checknet or
Interpoll) no longer report scrambled entries.

Open Transport is now compatible with PowerShare 1.1, QuickMail 3.5 and
Meeting Maker XP Servers.

Changes to TCP/IP for Open Transport

Rebooting is no longer required between separate SLIP or PPP connections.
IP address may be different for each connection. You may need to quit and
reopen some applications (e.g., NSCA Telnet) between SLIP/PPP connections.

TCP/IP is now compatible with Netscape 2.0 as well as Netscape 1.12.

Compatibility with the StarNine Internet PMSAM, WebStar and some other
products has been improved. (A bug in the TCP/IP Backward Compatibility
library that related to re-using a closed TCP stream was fixed.)

Support for multiple simultaneous inbound connections (for example, in
applications such as WebStar) has been enhanced. (The TCP/IP Backward
Compatibility LISTEN architecture has been improved.)

A bug causing WebStar and similar applications to crash after receiving
numbers of connections has been fixed. Apple has run WebStar for
750,000 connections over 24 hours on various configurations without

Open Transport 1.1b16 now works with FTPd versions 2.3, 2.4, 3.0 & 4.0
NetPresenz. We believe FTPd versions 2.4 & 4.0 work better than version

Open Transport is working closely with the Apple Internet Mail Server
development team on compatibility requirements.

TCP/IP no longer ignores the hosts file when no DNS server address is

A Generic DNR interface is now provided offering developers an enhanced
interface to the DNR. Third-party software can now submit a pre-formatted
request to the DNR It will be transmitted and results returned to the
requesting program. Results are limited only by the number of memory
code allocated by the requesting program. Third-party developers can now
HESIOD support to applications using the new DNR generic interface.

MXInfo and SysInfo interfaces are now supported by MacTCP Emulation in
Transport TCP/IP.

Open Transport 1.1b16 now automatically adapts to DHCP servers' packet
requests whether padding to a fixed packet size is required or prohibited.

Compatibility with BOOTP and DHCP servers has been improved, including
for servers more than zero hops away.

A compatibility problem between Timbuktu 2.0 using TCP/IP was fixed.
versions 1.0.8 and later are compatible with Open Transport TCP/IP.

Open Transport now works correctly with The Starnine PowerTalk Internet
PMSAM's ping option. This software is available for free from Apple at:

Resolution of several bugs has yielded increased performance for Open
Transport native applications using TCP_NODELAY (for example, FileMaker

This version of Open Transport is compatible with CU-SeeMe from Cornell

Compatibility has been improved with eXodus from White Pine Software,
XSoftware from AGE and MacX.

The Cornell Comet 3.1.3 Terminal Emulator no longer reports "MacTCP:
Length" when trying to make a connection.

Compatibility with third-party SLIP and PPP mdevs has been extended to

Open Transport is now compatible with Nubus Token-Ring adapters. Because
of a
need to be compatible with existing Nubus Token-Ring drivers, Open
TCP/IP artificially imposes a MTU of 1500 bytes. This limit is expected
to be
raised in a future release.

Old style (obsolete RFC 793) OOB (Out-Of-Band) has been added to Open
Transport TCP/IP (MacTCP Emulation only) to increase compatibility with
Sybase 68k 10.0.3 client. Previously, cancelling a request made the next
request hang.

A bug in Bolo was fixed. (If you experience problems, make sure you have
most recent version of Bolo.)

Spyglass Mosaic now works properly through a proxy server.

Meeting Maker XP now works properly when TCP/IP preferences are not set up
(whether you use TCP/IP or AppleTalk).

The TCP/IP control panel was changed to more accurately reflect the
reality of
MacIP usage today. In MacIP server mode, the subnet mask and router
fields now disappear because they aren't used. In MacIP manual mode, the
subnet mask doesn't exist, but the router address does. In previous
these fields contained "<returned by server>" initially, then "<not

The TCP/IP control panel obtains multiple gateway and name server
via DHCP and BOOTP, but displays only the first one. This is expected to
addressed in a future release.

When TCP/IP is configured to connect via AppleTalk (MacIP), it now
all AppleTalk zones on large networks. The only limit is memory available
the list of zones.

When TCP/IP is set to "Load Only When Needed" (in the Options window),
"pinging" an Open Transport workstation may fail if TCP/IP is not
being used.

Balloon Help has been enhanced in the TCP/IP control panel.

Known Incompatibilities and Limitations

Open Transport 1.1b16 does not work with and cannot be installed on
and Power Macintosh 5200, 5300, 6200, and 6300 series computers, or on
Macintosh IIvi computers.

Open Transport 1.1b16 has problems on Macintosh PowerBook 190, 2300,
5300, and
upgraded 540 computers that use Mac OS 7.5.2. Apple recommends against
installing Open Transport 1.1b16 on these computers.

On the PowerBook 540, AppleTalk is turned off at boot time, requiring
AppleTalk to be turned on each time you restart. The workaround is to
version 1.2 or earlier of the "Assistant ToolBox" from the Extensions

If you use the 802.3 setting in the TCP/IP control panel, ensure that all
stations on your network segment are also configured to use 802.3 and not
ethernet II.

If you experience problems using MacPPP or FreePPP when Virtual Memory is
turned on, try turning off Virtual Memory. To find out how to turn off
Memory, see the topic "How do I use hard disk space as memory" in
Guide, available from the Guide (question mark) menu.

Open Transport 1.1b16 conflicts with the software that dims the screen of
PowerBook Duo computers when the PowerBook is docked and idle. The
is to replace this software with a 3rd party screensaver.

DHCP is not supported by a standard mechanism over dialup. A Windows NT
Server, when connected via Windows NT Client, uses proprietary mechanisms
support DHCP over dial-up links. This is documented in the DHCP FAQ
at :
The following is an excerpt from the DHCP faq:

"I am not currently aware of any way in which DHCP can support
served solely by PPP or SLIP. Such a computer doesn't have the IEEE-style
MAC address that DHCP requires to act as its key to determining which
client-computer is which within the same subnet. Communications servers
acquire IP numbers for their clients via DHCP run into the same roadblock
they have just one MAC address, but need to acquire more than one IP

NFS/Share 1.3.x and 1.4 are not compatible with Open Transport. NFS/Share
1.4.1 is compatible with Open Transport. To use NFS/Share with Open
contact InterCon to obtain a version of NFS/Share that is compatible with

Microsoft Mail 3.1 client software is compatible with Open Transport.
Microsoft Mail 3.1 server software is not compatible with Open Transport
will require an update.

MacTCP Ping is not compatible with Open Transport. No update is planned.
MacPing from Dartmouth is an alternative that is Open Transport

The LaserWriter Bridge and LocalTalk Bridge version 2.0.1 or earlier are
compatible with Open Transport

The currently shipping versions of Apple IP Gateway and AppleTalk Internet
Router are not compatible with Open Transport.
