Cant Get dhcpd to start after installing FOG on centOS 6.5
-
Hello All, I’m a newby as far as FOG and DHCP are concerned. After reading the install doco on FOG, I was able to install it and bring up the web interface. A bit more detail is that Fog is installed on the same server that will be be the dhcp server. In /etc/dhcp the file dhcpd.conf. Mine looks like this:
DHCP Server Configuration file.
see /usr/share/doc/dhcp*/dhcpd.conf.sample
This file was created by FOG
use-host-decl-names on;
ddns-update-style interim;
ignore client-updates;Fog’s IP address:
next-server 10.45.60.4;
Subnet where you are going to use Fog
subnet 10.45.60.0 netmask 255.255.0.0 {
option subnet-mask 255.255.0.0;
range dynamic-bootp 10.45.60.50 10.45.60.200
default-lease-time 21600;
max-lease-time 43200;
option domain-name-servers 10.24.55.1 10.24.55.10;
filename “pxelinux.0”;
}This is my present “not working” dhcpd.conf
Let me also add that this server has 2 interfaces 10.45.60.XX and 10.45.110.XX.
I created this file from a file I found when searching under /etc/dhcp post FOG install.
No matter how I change it to meet several examples “other than changing my ip info…” I found on line, I’m unable to start the dhcpd daemon. My goal is to have a FOG & DHCP server providing ip’s for both the 10.45.60 and 10.45.110 subnets. I’m perplexed at this point and figured I need help from the experts…
If anyone has come across this scenario and can help, I would appreciate it. Also, if further information is needed I will provide it ASAP.
Thanks in advance!

Forgot to add that the images I will take and restore are a Windows/Linux dual boot image I keep on the FOG server under a filesystem names /images. This is a 1tb filesystem due to the several images that will reside there.

Hello again. I have been trying to solve this on my own and was able to get dhcpd running by changing the subnetmask to 255.255.255.0. I’m not sure why 255.255.0.0 will not work. I know this is not correctMy updated dhcpd.conf is below:
DHCP Server Configuration file.
see /usr/share/doc/dhcp*/dhcpd.conf.sample
This file was created by FOG
use-host-decl-names on;
ddns-update-style interim;

default-lease-time 21600;
max-lease-time 43200;
option domain-name-servers 10.24.50.1;

}Forgot to give the interface info, sorry:

The reason 255.255.0.0 won’t work is you’re trying have two dhcp servers within the same subnet. 255.255.0.0. Will provide dhcp to all systems with a 10.45.x.x address. To limit the address range to specific 10.45.60.x. You would need a subnet of 255.255.255.0. Same for the 10.45.110.x subnet.

Thank Tom!
I will reconfigure and give it another try. I appreciate your reply!!! -
I’m now getting the following error:
None of the machines were able to be queued!
[ftwlx132] Unable to connect to tftp server.
Please excuse my ignorance and lack of experience with tftp and dhcp…
Not sure where to go next. -
Adding more information related to tftp:
]# netstat -a|grep -i tftp
