-d Enables debugging (exceptional conditions and dump)
-v Logs all interesting events (daemon.info and console)
7.1.8.9 inetd Daemon
The inetd daemon creates AF_INET sockets for services that are tcp4 and udp4
and AF_INET6 sockets for services that are tcp6 and udp6. If the -6 option is
used, inetd creates AF_INET6 sockets for services that are TCP and UDP.
Otherwise, it creates AF_INET sockets for these services. The new members of
the servtab structure are se_family (address family) and se_ctrladdr_size (for the
differences in size of sockaddr_in and sockaddr_in6). Also, the se_un member
was modified to include the sockaddr_in6 structure. The config() function has an
added AF_INET6 case.
7.1.9 IPv6 Socket Library Support
Socket library support has been modified to allow for application developers to
begin porting to IPv6:
• IPv6 data structures (include files define these).
• socket(), bind() and connect() support the AF_INET6 address family and the
sockaddr_in6 address structure.
• ASCII print function is provided with inet_pton() and inet_ntop().
• Address/name translations with IPv6 addresses.
• Interface/index information retrieval.
• Address manipulation/query (in6_ifXXX(), XXX_ADDR6()).
• IPv6-specific getsockopt() and setsockopt() calls.
7.1.10 System Management Changes and Additions
The recommended method of configuring IPv6 is through SMIT. New SMIT
panels have been added and existing ones changed to achieve this. Existing
system configuration commands, such as mkdev and chdev, can also be used but
will not be described here.
The IPv6 configuration panels are reached through a new option added to the
standard TCP/IP panel, as shown in Figure 39.
