i just installed a woody DHCP server last night and ran accross your
2nd problem..
for the first, i would check /etc/resolv.conf, or do a WHOIS on the
domain your ISP uses and use those servers, they are less likely to
change, its possible the nameservers for their end users may change
for some reason ..
as for why dhcp complains I am not sure, but my setup involves only
running DHCP on eth1, i edited /etc/init.d/dhcp and changed the
INTERFACES variable from eth0 to eth1 but that still did not work
so i hard coded it into the script like this:
case "$1" in
start)
echo -n "Starting DHCP server: dhcp"
start-stop-daemon --start --quiet --pidfile $DHCPDPID \
--exec /usr/sbin/dhcpd -- -q eth1
echo "."
and it started immediately without complaining. i don't understand
why using the $INTERFACES variable did not work, but when I used
it with that variable my log said:
