Nothing to Boot error..any solution?

[Sebastian Roth]

In the pcap file I only see DHCP answers from 192.168.56.100. Which machine is this?

This seams kind of weird as there is no information about next-server or filename set in those DHCP answers. The client actually does not even try to boot from network or even get iPXE via TFTP.

Please run this again to the point where you see the above error.

Again my question: How are your network interfaces configured in virtualbox (hostonly, bridge, …)?

@Uncle-Frank
let me check back the cconfig…both virtualbox config with host-only adapter…

How do I setup my fog server as dhcp server?

[Sebastian Roth]

@adi I was a little confused about not seeing TFTP traffic in the packet dump (meaning that iPXE binary didn’t get transferred to the client to boot from) but you still see an iPXE error message. Haven’t used virtualbox for netbooting much lately and so I did not know that it actually uses iPXE as network boot binary in the first place (http://www.virtualbox.org/svn/vbox/trunk/src/VBox/Devices/PC/ipxe/src/usr/autoboot.c).

IMHO the easiest solution for you here is to add a proxyDHCP using dnsmasq on the FOG server. The virtualbox DHCP server will go on handing the IP address to the client and dnsmasq will add the important information to netboot the client.

sudo apt-get install dnsmasq
sudo apt-get remove isc-dhcp-server tftpd-hpa

The second command might fail but I just want to make sure that ISC DHCP and TFTPd are not getting in the way as dnsmasq will do the job for you. Then edit /etc/dnsmasq.conf to your needs. Here is an example for your setup. I am not able to test this so there could be minor errors in it. Look over it and make sure to correct things as needed:

# Don't function as a DNS server:
port=0

# Log lots of extra information about DHCP transactions.
log-dhcp

# Dnsmasq can also function as a TFTP server.
enable-tftp

# Set the root directory for files available via FTP.
tftp-root=/tftpboot

# The boot filename, Server name, Server Ip Address
dhcp-boot=undionly.kpxe,192.168.56.102,192.168.56.102

# Disable re-use of the DHCP servername and filename fields as extra
# option space. That's to avoid confusing some old or broken DHCP clients.
dhcp-no-override

# PXE menu.
pxe-prompt="Press F8 for boot menu", 3

# Tells the client to load undionly.0 from TFTP
pxe-service=X86PC, "Boot from network", undionly

# This range(s) is for the public interface, where dnsmasq functions
# as a proxy DHCP server providing boot information but no IP leases.
dhcp-range=192.168.56.102,proxy

And to finish things up you need to link the boot file and restart dnsmasq:

sudo ln -s /tftpboot/undionly.kpxe /tftpboot/undionly.0
sudo service dnsmasq restart

Then bootup your windows client and keep fingers crossed.

Hi

Seem like it tried to contact fog server…but it keeps on restarting

[adi]

@Uncle-Frank
here is my tcpdumplog1.pcap

fog server :192.168.100.10
client:192.168.100.11(get ip via dhcp from fog server)

[Sebastian Roth]

Could you please help us with some more information. Why have you changed IP addresses (is there a reason we should know)? Seams like you have configured a “normal” DHCP now, not proxyDHCP. Also your FOG server MAC address seams changed. Please tell us what you’ve done and best also post the configs you are running. Otherwise it is all very hard guesswork.

Hi

It success upload image now.\0/. THANKS

Any private IP address can be set. In virtualbox environment, I just want to test that the Fog server is able to contact with client DIRECTLY without any dhcp server in the middle between fog server and client…This is what I did

step 1
just install fog server with you reference link or wiki.when it comes to part saying “If you already have DHCP configured, Press NO to disable FOG DHCP”…click YES. the reason is you want your fog server act as dhcp server and will give IPs to client.

step 2
Make sure both client and fog server interface adapter on virtualbox are set into Internal Network. On client system boot order on virtualbox, set to harddisk first.

Step 3
Set static IP for server and set obtain DHCP on client.(fog server will give IP to client)

Step 4
On Fog server run command ufw disable, service tftpd-hpa restart and service isc-dhcp-server restart. While on client just monitor until client received IP from FOG server. Once received IP, test both can ping each other.

Step 5
Once both can ping each other, install FogPrep on client then click shutdown. On Fog server run upload image (follow reference link)

Step 6
Go to client system boot order, change to Network. and then start client virtual. Fog GUI will appear.

Done.

Great to see that you got it solved yourself. Quite different to how I would have done it but that’s the good thing about FOG and IT in gerneral: There is always more than one way of doing it. Have fun with FOG!
