My first thought would be "don't run Linuxconf", but I realize that doesn't
help much. Although it appears to be improving, I still find it doing
things I don't want, not doing things I do want and doing other things for
reasons unknown.
I don't know why linuxconf/netconf would be doing this as I don't use it on
my production servers, but what you may want to do is edit dhcpd's startup
script ( /etc/rc.d/init.d/dhcpd ) like so:
case "$1" in
start)
# Start daemons.
echo -n "Starting dhcpd: "
daemon /usr/sbin/dhcpd eth0 <--CHANGE THIS LINE
echo
touch /var/lock/subsys/dhcpd
;;
In the above script, add the ethernet devices that dhcpd should listen
on. I *don't* know if linuxconf/netconf will (a) modify this line later or
(b) still stop/restart dhcpd with incorrect interfaces.
