Hello all,
In the environment that I work, I have to NIC's. One ethernet, one
token ring. I only want the dhcp server to listen for requests on the
token ring nic. So, I read the dhcpd manual page and found that if
interfaces are specified on the command line that dhcpd will only listen
on those addresses.
Ok, so I found the dhcpd script (later I found that I should have added
this to /etc/sysconfig/dhcpd but the result is the same) in /etc/init.d
to include the following line:
DHCPDCMDARGS="tr0"
Then, later on this is referenced when dhcpd is started. Ok, now comes
the problem. After starting dhcpd, I do a nmap -sU on both interfaces
and see the both eth0 and tr0 (when I call nmap, I call their respective
IP addresses) have port 67 on udp open. Why is this? If the addition
of "tr0" to the command line options is supposed to keep this from
happening, why is it happening? Am I missing something?
