Network Boot Problems/Computer won't communicate with Ubuntu/FOG

Matt Harding

Can you post your configs here? I’m not saying I’ll be able to help as I dont use a DHCP Proxy myself, I have full control over my DHCP setup so I’ve no need of one, but there are plenty of people on this forum with loads of experience that may spot the problem straight away.

Adam Kohnert

What is the best way to show you how I have it set-up?

Matt Harding

I was hoping to see your dhcpd.conf file on your dhcp server. When you say you had no luck I take it then that you mean you couldn’t get onto it to alter the config? I thought perhaps you meant that you had tried unsuccessfully to modify it.

Have you used Wireshark before? Great tool for finding out whats going on at the heart of a network. I think it’d come in real handy for you in dealing with this issue too. Give it a go. If you’ve never used it before it can seem very complicated and overwhelming, but its quite straight forward for beginner use anyhow. Install it, run it, and select your chosen interface to watch on near the top left. Once you’ve done that it will immediately start live capture of packets.

What I suggest you do is run this on a machine on your network to observe what is happening, and while its running, try to boot another PC from the network. Watch for packets of the DHCP variety. You’ll see them come up under the DHCP Protocol, and in the INFO field next to it will be “DHCP Request” followed by a couple of “DHCP Discover” entries. Click on the discover line(s) and take a closer look in the main information window below the list (bottom half of the screen). Somewhere down there will be an entry that says “Bootp flags” and within that will be the line “Next Server IP address”. If there is nothing there but “0.0.0.0 (0.0.0.0)” then your dhcp server is not giving out bootp addresses which is what gives a network booting machine the ability to talk to fog’s tftp server.

In short if you only get 0.0.0.0 there then your good to go and can use the dhcp proxying method of supplying the extra details. If it does pick up an address, you really need to get in touch with the people who maintain the system giving out the addresses and explain your situation because if its giving bootp addressing out, its not directing you where you need to go, and you cant change it.

Hope I haven’t confused you too much

I’m sure there’s easier ways to say what I’m trying to get accross and perhaps if you are still in need of help with this, someone can convey in a more human friendly way the essence of what I am trying to get across.

Oh incidentally the URL for the wireshark download is:

The FOG project wiki article on proxyDHCP is based on Ubuntu and LTSP, and has specific instructions. search the wiki for proxyDHCP

Adam Kohnert

Good news all!

We purchased a new Firewall/Filter (CIPA) and it came in today and it is up and running!

It looks like there is a place for us to modify it so we can add:

next-server 10.0.175.162;
filename “pxelinux.0”;

Note the filename end of .0 is a zero.

Is there anything else that we need to add???

YeeHaa

Thanks

Matt Harding

Put those settings in (Remember to make note of what you do in case you need to take it out again).

Register a client PC with fog through the web frontend, set it to PXE boot, then see if it boots from network and shows you a FOG menu. If you get the fog menu, its worked.

Adam Kohnert

Well…

We can’t seem to change any settings on the DHCP server

Plan D

Can we set up our own network? Just have the fog server hooked up to a switch then have some computers hooked up to a switch? And then have the FOG server give out DHCP address?

I am at a loss…I have about 75 computers to do

Thanks

During the install process for FOG it asks if you would like to have FOG manage your DHCP. If you don’t have any images or a long list of hosts added to FOG already, it might be easiest to just set it up one more time from scratch on an isolated switch, making sure to let FOG handle DHCP.

Adam Kohnert

OK, is there a way I can change my current settings without uninstalling FOG? Should I be connected to our current network when I install FOG? What IP address do I use for the FOG server?

Thanks again

chad-bisd

Yes. install the DHCP daemon and configure it manually.

Adam Kohnert

Hello again!

Here is what I did and it didn’t work, I know shocking:

Set up my fog server to handle DHCP…I think
Connected my fog server to a switch no hooked to the internet
Connected the client to the same switch as the fog server
And…nothing

Can someone check my fog settings?

I can’t have my fog server hooked to our current network…it causes some problems

Thanks!!!

chad-bisd

post your dhcpd config file (use code tags or attach the file).

When you says “And…nothing” what part of the process gives you nothing? Maybe if you spelled out the exact steps you are taking when trying to use FOG when the “And…nothing”, we might be able to help. You can configure FOG all day long, but if you don’t turn on the clients “and…nothing” is an expected and acceptable result.

Adam Kohnert

Sorry for being vague
And…nothing—this means the client machine did not boot from PXE

Did I miss a step?
Probably something simple

Thanks Again

chad-bisd

Did you go into the BIOS on the clients and set them to network book, and then actually make sure they are network booting. Some require you to hit F12, or hold down a key before they network boot, even if it’s set in the BIOS. I have some tablets that I have to hold down a special button on the front while turning them on, or they ignore the boot order and quick boot to windows.

Adam Kohnert

Yes, I hit F12 and selected Boot From PXE.

Ill keep trying.

Thanks again

Adam Kohnert

Hello again!

I was thinking one day and thought I may need 2 network cards for my computer to make FOG work? Not sure why, So I tried it and the computer did not boot from PXE.

So then my next venture was to start from scratch, so I reinstalled FOG. Then I got this message-- * Setting up and starting Apache Web Server…Failed!

So here is my current set-up

That is as far as I got. I did take out the extra card. Here is my network information.
IP-10.0.175.162
Broadcast Address-10.0.255.255
Default Router-10.0.0.2
Primary DNS- 64.33.128.10

Our current DHCP server can’t be modified. So I selected FOG to handle DHCP. I hope I was detailed enough! Thanks!

I am going to get a fresh start. I am going to reinstall Ubuntu 11.04 version

Adam Kohnert

Success!!! I am in the process of uploading an image!!!

Woohooo!!!

Adam Kohnert

Cloned 6 computers in about 20 minutes!!!

Thanks for the all the help

@Adam-Kohnert In case there are others who may have had this issue I have corrected a PC not booting into PXE a few times.

Steps I have taken to correct:

Boot into BIOS
Change the security settings to remove Secure boot
change boot type (away from UEFI to BOTH)
Set Legacy to first on the boot options.

This has corrected my issues every time
