	I've got two NICs on my primary.  dc0 goes to my router;
	dc1 goes to my hub.  All are running unix.  So far, I 
	have rebooted only my laptop.  I can immediately ssh from
	my latop *into* my primary (DNS) server, but when I try to
	ping anywhere from my laptop, nothing--it times out.
	So my dhcpd isn't handing out leases.  

	In /etc/rc.conf I've got:

	dhcpd_flags="-q"                                # command option(s)
	dhcpd_conf=/usr/local/etc/dhcpd.conf    # configuration file
	dhcpd_ifaces="dc1"              # ethernet interface(s)
	dhcpd_withumask="022"                   # file creation mask

	So far, the dhcpd_ifaces doesn't seem to be working, 
	although I *do* see it when I do a grep on 
	'sh -x on /usr/local/etc/rc.d/isc-dhcpd.sh::

	+ network_interfaces=dc0 dc1 lo0
	+ ifconfig_dc1=inet 10.0.0.1  netmask 255.0.0.0
	+ dhcpd_ifaces=dc1

	So the script at least is reading /etc/rc.conf.  Why dhcpd
	isn't seeing this is unknown.


	Here is part of my dhcpd.conf:


option dhcp-server-identifier 10.0.0.1;
option domain-name "thought.org";
option domain-name-servers 216.231.41.2, 66.93.87.2;
option routers 10.0.0.1;
option subnet-mask 255.0.0.0;
server-name "sage";
server-identifier 10.0.0.1;

	So far, rebooting ns1.thought.org (== sage) and my laptop
	don't change anything.
