Open Transport
2.0.1
|
Open Transport is the networking technology for
Mac OS 8.5. Open Transport 2.0.1 contains SNMP and OT
SNMP Admin, DHCP enhancements for improved compatibility
with Windows NT, including Client ID, new APIs for
manipulating configurations, scriptability for AppleTalk,
TCP, Modem, Remote Access, Infrared control panels, and
bug fixes.
- The Dynamic Host Configuration Protocol (DHCP)
implementation now supports a number of much-requested
features, including Client Identification, retention of
the lease on a given IP address across boots, better user
feedback in the event that the DHCP server is
unavailable, and better support of RFC 2131. Many of
these changes address customer concerns about OT's DHCP
compatibility with Windows NT DHCP servers.
- 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 will be provided.
- Minor changes to Open Transport support for Apple
Remote Access to allow feature requests such as support
for MS-CHAP Authentication support and RFC 1877 to
automatically negotiate DNS address with a server. These
changes address customer concerns about OT's
compatibility with Windows NT PPP servers.
- If Open Transport TCP/IP is configured to use DHCP
and it receives no response from any DHCP server within
30 seconds, it will dynamically assign a temporary
address in the local non-routable self-assignment range
(169.254.x.x) and operate using this address until a DHCP
server becomes available. This allows hosts on the same
Ethernet to communicate with each other using IP (for
example, to allow high-performance TCP/IP access to an
AppleShare IP server) even if no connection to the
Internet is available.
