Problem with dhcp options configuration

[Leandro Silva]

Hello i instaled the fog version 1.0.1 yesterday and tried to configure it with my existing mikrotik dhcp server.

The fog is on the same netowork as my host machines, in the dhcp server i created the 66 and 67 options as follows:

Name Code Value
next-server 66 172.16.8.2
bootfile 67 pxelinux.0

but my host machines give me a message that no configuration are recieved from dhcp, is there any other option that i have to create?
When i installed fog i choose no when it prompt for it to be the dhcp server.

[B]Fog v1.0.1 bootfile should be undionly.kpxe[/B]

FOG now has everything it needs to setup your server, but please
understand that this script will overwrite any setting you may
have setup for services like DHCP, apache, pxe, tftp, and NFS.

It is not recommended that you install this on a production system
as this script modifies many of your system settings.

This script should be run by the root user on Redhat or with sudo on Ubuntu.

** Notice ** Redhat users will need to disable SELinux and iptables in
order to use FOG
Please see our wiki for more information at [url]http://www.fogproject.org/wiki[/url]

Here are the settings FOG will use:
Base Linux: Debian
Detected Linux Distribution: Ubuntu
Installation Type: Normal Server
Server IP Address: 172.16.8.2
DHCP router Address: 172.16.8.1
DHCP DNS Address: 172.16.0.106
Interface: p4p1
Using FOG DHCP: 0
Internationalization: 0
Donate: 0

     DHCP will NOT be setup but you must setup your
     current DHCP server to use FOG for PXE services.

     On a Linux DHCP server you must set:
         next-server

     On a Windows DHCP server you must set:
         option 066 & 067

               Option 066 is the IP of the FOG Server: (e.g.
               Option 067 is the undionly.kpxe file: (e.g. undionly.kpxe)

it’s complaining it can’t get an IP address.

what is your DHCP server running on?

I’ve had this a small amount at my current place of work, but it is only laptops plugged in via their Ethernet ports…

Is this a type-o or did you really enter your ip address as 172.16. 8.1 because there is a space in there.

[Leandro Silva]

i’m using a mikrotik as router and dhcp server for this network segment and my fog server and host machines are geting dhcp from it.

Another possibility is to install the dnsmasq service to help alleviate the issues of trying resolve your dhcp information.

Now something came to my mind, i’m using supernetting in this network, my network is 172.16.8.0/21, the pxe protocol supports supernetting?

[Leandro Silva]

sorry subnetting, bad english

[VincentJ]

I use a 10.x.x.x with 255.255.248.0 subnet mask, works fine for me.

[Leandro Silva]
