dhcpd のインストール
$ sudo port -vc install dhcp
###########################################################
# A startup item has been generated that will aid in
# starting dhcp with launchd. It is disabled
# by default. Execute the following command to start it,
# and to cause it to launch at startup:
#
# sudo port load dhcp
###########################################################
NOTE:
-The dhcpd .conf and .leases files must be named and located as shown for dhcpd to find them:
/opt/local/etc/dhcp/dhcpd.conf (there is a sample file)
/opt/local/var/db/dhcpd/dhcpd.leases (use the touch command to create a blank one)$ port contents dhcp
Port dhcp contains: /Library/LaunchDaemons/org.macports.dhcpd.plist /opt/local/bin/omshell /opt/local/etc/dhcp/dhclient.conf.sample /opt/local/etc/dhcp/dhcpd.conf.sample /opt/local/etc/LaunchDaemons/org.macports.dhcpd/org.macports.dhcpd.plist /opt/local/include/dhcpctl.h /opt/local/include/isc-dhcp/boolean.h /opt/local/include/isc-dhcp/dst.h /opt/local/include/isc-dhcp/int.h /opt/local/include/isc-dhcp/lang.h /opt/local/include/isc-dhcp/list.h /opt/local/include/isc-dhcp/result.h /opt/local/include/isc-dhcp/types.h /opt/local/include/omapip/alloc.h /opt/local/include/omapip/buffer.h /opt/local/include/omapip/omapip.h /opt/local/lib/libdhcpctl.a /opt/local/lib/libomapi.a /opt/local/sbin/dhclient /opt/local/sbin/dhclient-script /opt/local/sbin/dhcpd /opt/local/sbin/dhcrelay /opt/local/share/man/cat1/omshell.1.gz /opt/local/share/man/cat3/dhcpctl.3.gz /opt/local/share/man/cat3/omapi.3.gz /opt/local/share/man/cat3/omshell.3.gz /opt/local/share/man/cat5/dhclient.conf.5.gz /opt/local/share/man/cat5/dhclient.leases.5.gz /opt/local/share/man/cat5/dhcp-eval.5.gz /opt/local/share/man/cat5/dhcp-options.5.gz /opt/local/share/man/cat5/dhcpd.conf.5.gz /opt/local/share/man/cat5/dhcpd.leases.5.gz /opt/local/share/man/cat8/dhclient-script.8.gz /opt/local/share/man/cat8/dhclient.8.gz /opt/local/share/man/cat8/dhcpd.8.gz /opt/local/share/man/cat8/dhcrelay.8.gz /opt/local/var/db/dhcpd/.turd_dhcp /opt/local/var/db/dhcpd/dhcpd.leases
