[quote=“purpleturtle99, post: 33427, member: 23775”]Okay when I stop the DNSMASQ services and let my Cisco router dish out IP’s via DHCP then laptop receives an IP address and the errors are PXE-E53 and PXE-M0F

To be expected there is probably a misconfiguration with the DHCP next server and bootfile name, but some people don’t even attempt settings at the DHCP server if they intend to use DNSMASQ as it will not be necessary.
[quote=“purpleturtle99, post: 33427, member: 23775”]When I start the DNSMASQ services and remove the fog from the config file I get errors PXE_E51 no DHCP or proxyDHCP offers were received
And wiresharks shows the same result DHCP discover only messages. So I think the laptop never gets an DHCP offer from the fog server running DNSMASQ…What am I missing here???
BTW also from the ltsp.conf file what range of IP address is my fog server dishing out anyway???and how do I check this in the ltsp.conf file[/quote]
It might be worth downloading the Cisco CNA program from the cisco website so that you can check the settings of your switches.
Now load up the CNA program and select the switch in question (they will probably ALL have to be configured this way to pass the boot file) Log into your managed switch with the administrative username and password.
Click Configure on the left hand side. Choose Port Settings from the list.
Select all ports to be used for PXE boot. Click Modify. Enable Port Fast. Save. Close open windows.
This might help to solve some of the problems you are facing. Now To answer the question about DNSMASQ:
#[B] This range(s) is for the public interface, where dnsmasq functions[/B]
[B]as a proxy DHCP server providing boot information but no IP leases.[/B]
#[B] Any ip in the subnet will do, so you may just put your server NIC ip here.[/B]
[B]Since dnsmasq is not providing true DHCP services, you do not want it[/B]
[B]handing out IP addresses. Just put your servers IP address for the interface[/B]
#[B] that is connected to the network on which the FOG clients exist.[/B]
#[B] If this setting is incorrect, the dnsmasq may not start, rendering[/B]
[B]your proxyDHCP ineffective.[/B]
dhcp-range=10.0.0.10,proxy
I bolded the important parts, funny they are included in your text file and the wiki… That 10.0.0.10 is what you want to change to your fog server ip address, or something similar.
