7.1.11 IPv6 and IPSec-Related RFCs Implementation Table 36 shows the RFCs that have been implemented in the IP Version 6 support included with AIX Version 4.3.0. Please consult these RFCs, or their successors, for the latest information on IP Version 6 protocols. Table 36. RFCs Implemented in AIX Version 4.3.0 RFC number RFC Title 1825 Security Architecture for the Internet Protocol 1826 IP Authentification Header (AH) 1827 IP Encapsulating Security Payload (ESP) 1828 IP Authentification Using Keyed MD5 1829 The ESP DES-CBC Transform 1883 Internet Protocol, Version 6 (IPv6) Specification 1884 IP Version 6 Addressing Architecture 1885 Internet Control Message Protocol (ICMPv6) for IPv6 1933 Transition Mechanisms for IPv6 Hosts and Routers 1970 IPv6 Stateless Address Autoconfiguration 1971 Neighbor Discovery for IP Version 6 (IPv6) 7.2 IP Security Enhancements (4.3.1) AIX 4.3.1 has added new functions to IP Security: • Triple-DES is an additional choice for U.S. and Canada customers. • Performance improvements have been made to the CDMF and DES encryption. • The filter table now supports unlimited number of rules. • Any combination of installed authentication and encryption algorithms can be used for ESP with Authentication. In addition, new parameters have been added to the following IPSec commands: • exptun • imptun • mktun • rmfilt 7.3 TCP/IP Command Security Enhancement (4.3.1) AIX Version 4.3.1 offers secure remote TCP/IP commands: rsh, rcp, rlogin, telnet, and ftp. With this capability, Kerberos 5 authentication is used between these commands and server daemons, avoiding the need for user passwords to pass in the clear on the network. Instead, Kerberos 5 credentials are used to authenticate users. User credentials can be forwarded to the server. 166 AIX Version 4.3 Differences Guide
7.4 Dynamic Host Configuration Protocol Enhancements (4.3.1) A new command dadmin has been added to assist the DHCP administrator. The dadmin command lets the DHCP administrator query and modify the state of his DHCP servers’ databases. It gives the administrator the ability to locally or remotely query the DHCP server for the status of an IP address, query for a pool of IP addresses, query for a client, delete an IP address mapping, refresh the server, and change the server’s tracing level. The dadmin command is backwards compatible with previous AIX release DHCP servers to list their IP address status and refresh. When querying for IP address information, the dadmin command returns the IP address’s status, and depending on this, may return the lease duration, start lease time, last leased time, whether the server supports DNS A record updates for this IP address, and the client identifier that is mapped to this IP address. When querying for client information, the dadmin command returns the client’s IP address and IP address status, whether the server supports DNS A record updates for this IP address, the last time the client was given any IP address, and the hostname and domain name used by the client. When modifying the server tracing level, the dadmin command sets and returns the server tracing level in the form of a tracing mask. This mask represents a bit string, where each bit represents whether a specific log item is being traced by the server (see DHCP Server Configuration in the online documentation). From least significant to most significant order, these log items are LOG_NONE, LOG_SYSERR, LOG_OBJERR, LOG_PROTOCOL and LOG_PROTERR (same value), LOG_WARN and LOG_CONFIG (same value), LOG_EVENT and LOG_PARSEERR (same value), LOG_ACTION, LOG_INFM, LOG_ACNTING, LOG_STAT, LOG_TRACE, LOG_START, and LOG_RTRACE. 7.5 TFTP Block Size Option (4.3.1) The implementation of TFTP in AIX Version 4.3.1 has been enhanced to include the Block Size Option proposed in RFC 1783. Older implementations of TFTP relied upon a fixed block size of 512 octets that although easy to code and implement in the limited ROM space available in some clients, proves to be very inefficient on LANs whose MTU size may be 1500 octets or more. This implementation of TFTP has modified the TFTP Read Request and TFTP Write Request packets to include a block size option. When a client sends a read or write request, it can now include an option to request that the server uses a block size other than 512 octets. If the server is willing to accept the blocksize option, it responds with an Option Acknowledgment (OACK) containing the blocksize that must be equal to, or smaller than, that requested by the client. If the client is unable to accept the blocksize returned by the server, it must reply with an error packet and terminate the transfer. Tests on the performance of TFTP with different blocksizes have revealed that file transfer time can be reduced by as much as 80 percent by using larger block sizes. Networking Enhancements 167
