Info

There are new no options added: • ip6forwarding This option works like the existing ipforwarding only for IPv6 packets. The IP packets forwarding function will be enabled by the following command: #no -o ip6forwarding=1 The value of ipforwarding specifies whether the kernel should forward packets. The default value of 0 prevents forwarding of IP packets. A value of 1 enables forwarding. • multi_homed • main_if6 • main_site6 • site6_index 7.7 Enhancement for ifconfig Command (4.3.2) The new flags introduced to ifconfig command are: ifconfig [ -m ] Interface [ ProtocolFamily ] Interface ProtocolFamily ifconfig -a [ -m ] [ -d ] [ -u ] [ ProtocolFamily ] Table 37 provides the descriptions of the new ifconfig flags: Table 37. ifconfig New Flags for Display Interface Information Flags Descriptions -a The -a flag can be used instead of an interface name. This flag instructs ifconfig to display information about all interfaces in the system. -d The -d flag displays interfaces that are down. -m If the -m flag is passed before an interface name, ifconfig will display all of the supported media for the specified interface. -u The -u flag displays interfaces that are up. 7.8 Latest BIND DNS (NameD) Support (4.3.2) The Domain Naming System (DNS) is a method to distribute a large database of IP addresses, hostnames, and other record data across administrative areas. The end result is a distributed database maintained in sections by authorized administrators per domain. AIX, similar to other UNIX platforms, offers the BIND DNS server. BIND, or the Berkeley Internet Name Daemon, is a DNS server implementation provided by the Internet Software Consortium. It has become the standard for DNS server implementations and a benchmark for DNS server intercompatibility. AIX 4.3.2 incorporates IBM DNS value-added functions to the latest level of BIND, Version 8.1.2. This involves adding IBM secure dynamic DNS update protocol and incremental zone transfers to BIND 8.1.2, as well as extending this BIND's NOTIFY ability and parameter configuration. 172 AIX Version 4.3 Differences Guide
The following are the new functions provided Bind Version 8.1.2: • Secure dynamic DNS updates Currently, BIND offers only the unsecured RFC 2136 update protocol. This is an insufficient offering to customers desiring to implement a dynamic DNS environment in their networks. The secure update protocol is added as the solution for RFC 2136's insecure shortcomings and to provide backward compatibility with current AIX dynamic DNS customers. • Incremental zone transfer Implement the RFC 1995 Incremental Zone Transfer protocol. This protocol defines a method through which secondary DNS servers can update their existing zone data to incorporate all the cumulative changes to the primary zone since the last transfer. This protocol supersedes the performance of ordinary zone transfers by limiting the amount of network traffic between primary and secondary DNS servers and the subsequent computation time in incorporating an entirely new zone. The protocol ensures that incremental zone transfers can be sent to indicate changes from both dynamic updates and from zones changed on disk (those reincorporated through a refresh signal or server restart). • Notify Implementing the RFC 1996 Notify process. This is a method by which the primary DNS server can indicate to its secondary nameservers that zone data has been updated. This decreases the time periods in which a secondary DNS server will have data out of synchronization with its primary DNS server. • File Conversion Utility Extending the configuration file conversion utility to support IBM functional additions to previous BIND releases. This involves mapping the dynamic keywords of previous named.boot files to a functional equivalent in the named.conf configuration file. • Proprietary protocol for secure updates of dynamic notify dynamic zones. Bind 4.9.3 is available using named4. Bind 8.1.2 uses named8. 7.9 Web Server Performance Improved (4.3.2) Web server workload has a large number of small file operations. In smaller file operations, the cost of processing connection set-up/tear-down far exceeds the data touching (such as copy or checksum) operations. By reducing the number of packets that are sent or received for connection set-up/tear down, performance is improved. IBM has developed a set of TCP changes to reduce the number of packets from 9 to 7 or 6. For Web transaction oriented environments using HTTP protocols, AIX Version 4.3.2 reduces the number of network packets that are exchanged between the workstation and the server. This lowers the CPU packet processing overhead, increasing server performance and capacity. Networking Enhancements 173
