Contribution of a working dhclient-script for AIX would be welcome. + MacOS X + +The MacOS X system uses a TCP/IP stack derived from FreeBSD with a +user-friendly interface named the System Configuration Framework. +As it includes a builtin DHCPv4 client (you are better just using that), +this text is only about the DHCPv6 client (``dhclient -6 ...''). The DNS +configuration (domain search list and name servers' addresses) is managed +by a System Configuration agent, not by /etc/resolv.conf (which is a link +to /var/run/resolv.conf, which itself only reflects the internal state; +the System Configuration agent's Dynamic Store). + +This means that modifying resolv.conf directly doesn't have the intended +effect, so the macos script sample uses its own resolv.conf.dhclient6 in +/var/run, and inserts the contents of this file into the System +Configuration agent. Because the System Configuration agent expects the +prefix along with the configured address, and a default router, this is +not usable (the DHCPv6 protocol does not today deliver this information). +Instead, ifconfig is directly used for address configuration. + +Note the Dynamic Store (from which /var/run/resolv.conf is built) is +recomputed from scratch when the current location/set is changed, for +instance when a laptop is resumed from sleep. In this case running the +dhclient-script could reinstall the resolv.conf.dhclient6 configuration. + SUPPORT The Internet Systems Consortium DHCP server is developed and distributed |
