@Tom-Elliott YESSSSSS!!! I commented out line "port=0 ", and…voilá! I have full clonning system working, with fog machine capable to access the internet!
Thanks a lot my friends!

SOLVED!

@Tom-Elliott Hi Tom. Thanks for answering. Do you mean this line?:

• Don’t function as a DNS server:
  port=0

I have that line uncommented, I mean, it is runnning.

So you thought you´ll get rid of me easyly!..No sir, here I am again!..And of course…with troubles!
My old “dnsmasq issue” about the bug of the pxe boot file name (undionly.0 instead of undionly.kpxe) was solved, and my settings to make Fog work on my lan combined with my TPLINK router and its dhcp server works great!
Now, the new point is: when the ltsp.conf file is present (at /etc/dnsmasq.d), the fog clonning system works fine. But fog server machine LOSES INTERNET ACCESS!
But if I delete the ltsp.conf file and leave the dnsmasq.d folder empty, fog machine RECOVERS INTERNET ACCESS!
So, this make me think I could add a line or lines to ltsp.conf file, in order to keep Internet access. Is this correct? Whis are this lines? Or how to achive this?
Internet supplied by tplink router with dhcp embeded.
Thanks in advance to all of you.

@pabloinza Hi my friends. Finally i could solve this changing Ubuntu to ver 12.04. Here muticast works fine.

@Wayne-Workman Wayne!!..Ah ah!!..Savior of the Universe! Finally the solution! It finally works! I think the error is an issue of dnsmasq, since when I tried all of this stuff configuring Fog server machine as dhcp server, all worked fine, and in the dhcpd.conf file, the proper line said “undionly.kpxe”. So, I think dnsmasq is who´s mistaking the name of the file.
Well, what ever, it works!
Thanks a lot my friend! I really appreciate your help.
I don´t know how to tag this post as “SOLVED”. Would you please tell me?

@Wayne-Workman I´ve tried changing the line:

• dhcp-boot=pxelinux.0
  to
• dhcp-boot=undionly.kpxe
  and then the clients say “tftp file not found”

@Wayne-Workman Yes Wayne, I suppose that. In fact, I read that in this forum. But with my pour knowledge about Linux and all of this, I can´t achieve this. Would you please type for me the EXACT lines I need to put in my ltsp.conf file, and in any other place what ever I need to type or add or delete?

@Wayne-Workman Here is the screen capture of a pxe clien during boot process. This is the farther point I could reach

And if I change pxelinux.0 by undionly.kpxe, then it says “tftp file timeout, pxe file not found”

@Wayne-Workman Here is my ltsp.conf file:

- Sample configuration for dnsmasq to function as a proxyDHCP server,
- enabling LTSP clients to boot when an external, unmodifiable DHCP
- server is present.
- The main dnsmasq configuration is in /etc/dnsmasq.conf;
- the contents of this script are added to the main configuration.
- You may modify the file to suit your needs.



- 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. You may uninstall
- tftpd-hpa if you like, and uncomment the next line:
- enable-tftp

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

- The boot filename.
dhcp-boot=pxelinux.0

- rootpath option, for NFS
dhcp-option=17,/images

- kill multicast
dhcp-option=vendor:PXEClient,6,2b

- 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.  The first part is the text displayed to the user.  The second is the timeout, in seconds.
pxe-prompt="Press F8 for boot menu", 3

- The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86,
- Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI
- This option is first and will be the default if there is no input from the user.
pxe-service=X86PC, "Boot from network", pxelinux

- A boot service type of 0 is special, and will abort the
- net boot procedure and continue booting from local media.
pxe-service=X86PC, "Boot from local hard disk", 0

- If an integer boot service type, rather than a basename is given, then the
- PXE client will search for a suitable boot service for that type on the
- network. This search may be done by multicast or broadcast, or direct to a
- server if its IP address is provided.
- pxe-service=x86PC, "Install windows from RIS server", 1

- This range(s) is for the public interface, where dnsmasq functions
- as a proxy DHCP server providing boot information but no IP leases.
- Any ip in the subnet will do, so you may just put your server NIC ip here.
- Since dnsmasq is not providing true DHCP services, you do not want it
- handing out IP addresses.  Just put your servers IP address for the interface
- that is connected to the network on which the FOG clients exist.
- If this setting is incorrect, the dnsmasq may not start, rendering
- your proxyDHCP ineffective.
dhcp-range=10.10.10.101,proxy

- This range(s) is for the private network on 2-NIC servers,
- where dnsmasq functions as a normal DHCP server, providing IP leases.
- dhcp-range=192.168.0.20,192.168.0.250,8h

- For static client IPs, and only for the private subnets,
- you may put entries like this:
- dhcp-host=00:20:e0:3b:13:af,10.160.31.111,client111,infinite

@Wayne-Workman. Okay, but how come? The escenario works great if I disconnect the tplink router, connect all pc to a standard switch, and set the fog server pc as dhcp server; and there I don’t turn off anything, I don’t need to touch the fog server, default installation. So, why the need to touch its firewall?

Tomorrow I’ll post my dnsmasq file. Now, when you say “firewall off”, you mean my Tplink router’s firewall? Isn’t any specific port to open and forward in the Tplink router, in order to make this work, and avoid turning off all the firewall completely?

Hi my friends. My dhcp is that with comes embedded inside the TP-LINK WR 941 ND Router. So, I’d Iike to keep it using as dhcp sever, the clients leasing ip from it, and the clients being able to load the pxe file from the fog machine. And yes, all pc are in the same lan and same segment.

Hi folks. Has anybody could ever make Fog work on a lan, where a hardware router dhcp is already running and searving IP and DNS to the client computers (and don´t want to disable it).
I know we need dnsmasq to achieve that. Well, I follow this instruccions: https://wiki.fogproject.org/wiki/index.php/Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server
But couldn´t make it work yet.
During the PXE clients boot process, they get IP correctly (from the hardware router), they properly inform that there is a PXE file server (the Fog machine indeed), but then they stop booting informing that they couldn´t find the PXE file or something.
Any tip or intructions line by line to achieve this?
Thanks a lot.

@ch3i No problem pal. I´ll try to investigate. Thanks!

@Wayne-Workman said:

service FOGMulticastManager restart

Hi there. I colud solve this just restarting the pc and then it lets me restart the service whith: service FOGMulticastManager restart

@ch3i Ok, great! By the way, I´d like to install Fog WITHOUT dhcp service, on a PC which is currently running on a network that gets IP from the dhcp of a TP-LINK Router. I know I need to install dnsmasq service. I did it, the pxe clients get ip from the tplink router, but thay can´t reach properly the pxe boot file. Would you please give a hand whith this? The name of the files to edit and lines to type so as to let pxe clients boot prperly? Thanks so much!

@ch3i Hi ch3i. Thanks fot contacting. If I decide to try a newer version of Ubuntu, which one would you recomend me? What is SVN?

@ch3i Well well well…my last update of this thread:
I restart the system, restart fog server, restart FOGMulticastManager service, and yes!..now it restart successfuly and let me do a multicast!
I don´t know if it´s a momentary failure, if it´s my mistake or what. The point is I could solve it. I hope it keeps working!
Thanks to all of you. If I have nes I tell you.

@ch3i
/etc/init.d/FOGImageReplicator
/etc/init.d/FOGMulticastManager
/etc/init.d/FOGScheduler

Finally now I understand the sentences in Ubuntu are CASE sensitive!

So, I type again:
service FOGMulticastManager restart

and I get:
start-stop-daemon: warning: failed to kill 948: No such process

and the it fails to restart the service

How to solve it?
