\f1\b\fs36 Open Transport 2.0 Read Me - Part 1\ \ \

\fs24 Introduction\

\f0\b0\fs28 This Read Me document contains late-breaking information about Open Transport compatibility, add-on software, and solutions to known problems with third-party software. \f2\i For instructions about how to use the Open Transport control panels (AppleTalk and TCP/IP), use the Help Center, or open one of the Open Transport control panels and click on the help icon. \f0\i0 For additional technical information about Open Transport, see the \'d2Open Transport 2.0 Technical Info\'d3 file that came with Open Transport.\ \ \

\f1\b\fs24 Contents \f0\b0 \

\fs28 What\'d5s new in Open Transport 2.0 - general\ Bugs addressed\ Network interface options\ General compatibility\ Apple product compatibility update\ Dialup network connectivity - AppleTalk\ Dialup network connectivity - TCP/IP\ Native dialup network connectivity - AppleTalk\ Native dialup network connectivity - TCP/IP\ Tips for SLIP and PPP configurations\ Known limitations and other issues\ \ \

\f1\b\fs24 What\'d5s new in Open Transport 2.0 - general\

\f0\b0\fs28 \'a5 Open Transport 2.0 now supports AppleScript. Through the use of Network Setup Scripting (NSS) Macintosh owners can use AppleScript to configure all of the features of network communications currently available in the AppleTalk, Infrared, Modem, Remote Access, and TCP/IP control panels. These control panels continue to operate, with updates in this release. NSS will operate locally and remotely, offering powerful automation capabilities to end users and network administrators. \

\f3\b \

\f0\b0 \'a5 Open Transport\'d5s implementation of the Dynamic Host Configuration Protocol (DHCP) has been Improved to support a number of requested features: \ Client Identification. \ Retention of the lease on a given IP address across reboots.\ These changes address concerns about OT\'d5s DHCP compatibility with Windows NT DHCP servers.\ \ The Open Transport DHCP implementation has been enhanced to now support RFC 2131.\cf2 \ \cf0 Temporary generation of an IP address when no DHCP server is available (See OT 2.0 technical info document for more information).\ \ \'a5 When using the new DHCP Client ID feature, the Client ID is entered into a new field in the TCP/IP control panel. \ \ \'a5 Support for the Simple Network Management Protocol (SNMP) is available for Open Transport. Support for the version 2 Management Information Base (MIB II), instrumentation for AppleTalk and TCP/IP protocols and transports, administrative tools, and system agent support for the PCI bus is now provided. See the Open Transport SNMP Read Me on your Mac OS 8.5 CD for additional information.\ \ \'a5 In the latest release of the TCP/IP control panel (version 2.0), a feature has been added to simplify inputting the IP address and subnet mask for static IP addressing. Users can enter an IP address in standard "dot" notation in the "IP Address" text box, and immediately follow it with a slash ("/") and a number ranging from 1 to 32 indicating the number of contiguous one bits in the subnet mask, counted from the high-order bit. For example, if a user's IP address was "198.162.22.10", and the appropriate subnet mask was "255.255.255.252", the user could enter "198.162.22.10/30" in the "IP Address" text box. Once the box was tabbed past, the corresponding values would be entered into the "IP Address" and "Subnet Mask" text boxes. (This form of notation is supported in IPv6).\ \ 

\

\f1\b\fs24 Bugs Addressed \f0\b0\fs28 \ \'a5Open Transport 2.0 addresses an issue in which copying a large number of files from a mounted server could cause the server connection to time out and the client system to crash. 2223780\ \ \'a5This release fixes a problem where incorrect DNS lookups could crash OT DNR. 2217078 \ \ \'a5A bug in which rejected TCP connections could induce a relatively lengthy delay on the system initiating the connection has been fixed. 2206655\ \ \'a5Open Transport 2.0 now fixes several problems with the OT Printer Access Protocol (PAP) Server: \ OT PAP server would only allow 31 connections. 1656463 \ OT crashes after PAP spooler closed, after statechange error occurs. 1614825\ Crash when trying to print more than one document on LaserWriter software version 8.0 2209575 \ PAP server written to handle multiple connections will stop processing incoming data under some circumstances when there are multiple simultaneous connections. 2203018\ \ \'a5This version of Open Transport addresses cases where sleep could cause a crash or unexpected system behavior. 2218636\ \ \'a5Open Transport 2.0 has improved support for third party LocalTalk devices. 2235247\ \ \'a5 This release includes multiple fixes to improve compatibility, performance and stability on servers using AppleShare IP 5.0.2 and beyond.\ \ \'a5\'caAdditional bug fixes are included to the Open Transport to address problems with DHCP functionality, SNMP functionality, and to increase overall performance. \ \ \

\f1\b\fs24 Network interface options \f0\b0\fs28 \ Open Transport supports PCI bus, NuBus, communications slot, and PC Card network interface cards, as well as built-in LocalTalk, Ethernet, and Token Ring network adapters. For supported computers without expansion options, Open Transport 2.0 also supports a SCSI-attached network adapter. Third party network interface options available for Open Transport include Fast Ethernet, ATM, and FDDI.\ \ \

\f1\b\fs24 General compatibility \f0\b0\fs28 \ Open Transport is compatible with:\ \'a5 existing applications that use AppleTalk as specified by Apple Computer, Inc.\ \'a5 existing applications that use MacTCP as specified by Apple Computer, Inc.\ \'a5 existing devices (such as printers) that you select in the Chooser\ \'a5 existing NuBus network interface cards for the Mac OS\ \ Computers running Open Transport can be added to an existing AppleTalk or TCP/IP network without upgrading other computers on the network. \ \ \

\f1\b\fs24 Apple product compatibility update \f0\b0\fs28 \ \'a5 At Ease version 2.x or 3.x may encounter problems when starting up with Open Transport. At Ease Update 1.0 will update non-Workgroup versions of At Ease 2.x or 3.x to include Open Transport compatibility. If you are using At Ease for Workgroups, you should upgrade to version 3.0.2 or later. Both can be found on Apple Software Update sites on the Internet and selected online services. \ \ \'a5 Apple has exited the market as a vendor for Token Ring products. Apple has no plans for any new Apple-branded Token Ring products for Mac OS. The company also does not plan to offer any additional driver updates or hardware/software fixes for Apple's NuBus or PCI Token Ring cards. We will not be testing or shipping legacy Token Ring software in our new releases of Mac OS.\ \ Even though no further products, updates, or fixes are planned, Apple continues to recognize that selected Mac OS users have an ongoing requirement for Token Ring products. Towards this end, Apple has been closely working with Madge to ensure the availability of 3rd party Token Ring products that are compatible with the latest Apple hardware and the Mac OS operating system. Madge Token Ring products are available through authorized Madge resellers. Visit their web site at http://www.madge.com for more information.\ \

\f2\i \'a5 \f0\i0 Apple LocalTalk Bridge 2.1 is compatible with Open Transport. (See known incompatibilities for more information)\ \ \'a5 Apple Remote Access (ARA) Multiport Server 2.1, ARA Client 2.0.1 and later, and ARA Personal Server 2.0.1 and later are compatible with Open Transport 1.1 and later.\ \ \'a5 Apple PCI-based Workgroup servers (Application, AppleShare, and Internet) are compatible with Open Transport 1.1 or later.\ \ \'a5 Computers running the current versions of Apple IP Gateway and AppleTalk Internet Router must not be updated to Open Transport; these products are based on classic networking. These products do, however, interoperate with computers using either classic or Open Transport networking. Apple has not yet announced plans regarding future versions of these products.\ \ \'a5 Apple\'d5s MacTCP Ping is not fully compatible with Open Transport; no update is planned. MacPing from Dartmouth, available at \f1\b\fs20 <ftp://www.dartmouth.edu/pages/softdev/> \f0\b0\fs28 , OTTool from Neon Software, available at \f1\b\fs20 <ftp://ftp.neon.com> \f0\b0\fs28 and Mac TCP Watcher v2.0 from Peter N. Lewis & Stairways Software available at \f1\b\fs20 <http://www.stairways.com> \f0\b0\fs28 are Open Transport-compatible alternatives.\ \ \'a5 ZapTCP is a classic networking tool and is neither compatible nor needed with Open Transport. Functionality similar to ZapTCP is built into Open Transport. \
