well isn't 0.0.0.0 in linux means all interfaces? i didn't just want
dnscache to listen to localhost which is the default, i also wanted it
to listen to eth0. so i configured it to listen to all interfaces. all
applications that rely on resolv.conf works fine i guess except for
spamdyke v4.
# netstat -anp |grep 53
tcp 0 0 0.0.0.0:53 0.0.0.0:*
LISTEN 3075/dnscache
udp 0 0 0.0.0.0:53 0.0.0.0:*
3075/dnscache
# cat /etc/resolv.conf
nameserver 0.0.0.0
