dhcp question


Do you need to configure /etc/network/interfaces when setting up a DHCP server?

Not to my knowledge. You need to configure /etc/dhcpd.conf

Also if you have multiple interfaces, then you can specify which interface to provide the service in dhcpd.conf by adding
DHCPDARGS=eth0
this will provide dhcp service only on eth0.

It looks like you didn't specify a subnet. What does your dhcpd.conf look like?

Here is mine as an example:

Quote:
ddns-update-style interim;
ignore client-updates;
DHCPDARGS=eth0;

subnet 192.168.2.0 netmask 255.255.255.0 {

# --- default gateway
option routers 192.168.2.1;
option subnet-mask 255.255.255.0;

option nis-domain "egtech.us";
option domain-name "egtech.us";
option domain-name-servers 66.189.0.100,24.159.64.23,24.247.24.53,208.67.222.222,208.67.220.220;

option time-offset -18000; # Eastern Standard Time
# option ntp-servers 192.168.2.1;
# option netbios-name-servers 192.168.2.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
# option netbios-node-type 2;

range dynamic-bootp 192.168.2.128 192.168.2.254;
default-lease-time 21600;
max-lease-time 43200;

# we want the nameserver to appear at a fixed address
#host ns {
# next-server marvin.redhat.com;
# hardware ethernet 12:34:56:78:AB:CD;
# fixed-address 207.175.42.254;
#}
}

I figured it out, I had installed KestrelHPC before DHCP3-server. Apparently, this is a no no as KestrelHPC modifies the DHCP.conf and takes over DHCP duties.

Thanks for your help though! It's MUCH appreciated!
