OS: Debian Wheezy
DHCP Server: isc-dhcp-server 4.2.2
I need dhcpd to listen to the specific interface on a machine with 2 active NICs. I added INTERFACES="eth5" to /etc/default/isc-dhcp-server but dhcpd still listens to all interfaces:
root@server:~# netstat -46lpn | grep dhcp
udp 0 0 0.0.0.0:67 0.0.0.0:* 3229/dhcpd
udp 0 0 0.0.0.0:2174 0.0.0.0:* 3229/dhcpd
udp6 0 0 :::56980 :::* 3229/dhcpd
raw 0 0 0.0.0.0:1 0.0.0.0:* 7 3229/dhcpd
