Just Trying To Get Started
-
I restarted the tftpd-hpa service on the FOG machine, and I am now able to tftp the undionly.kpxe file inside a windows machine. Yay!
BUT, when I attempted to PXE boot the client machine (the HP Elitebook), the F8 menu timed out super-fast (as it had before).
Jaymes, I have started a download from cisco.com of the cna of which you speak. You may have opened a door to a whole new world for me:)
I will hopefully use it to check my switches for Port Fast functionality.
-
By the way, is it strange that I can’t use my FOG box to access the internet?
I was previously able to access the internet on the Ubuntu machine (I obviously downloaded the update to FOG 1.1.2 yesterday), but now I can’t browse to anywhere, other than local web servers (like the FOG interface or my web filter interface).
Just wondering if this has something to do with the major problem.
-
It could be possible, I know it is set this way in my environment as I work in education, that every devices is defaulted to a filter that is not allowing it to communicate with the outside world. This shouldn’t cause issues with pxe booting, but it will cause issues when trying to download directly to the server or to perform upgrades.
We are a Novell network with a cymphonix webfilter, I had to add my admin machines and my fog boxes to the filter bypass group, you may need to do something similar.
I am curious if you move the FOG server and a machine to a switch by themselves if the pxe menu will display, it should, but I am worried there may be more in your infrastructure that could cause issues with receiving the boot file in a timely manor.
Never fret, I have a solution if we need to use it, for now can you isolate a host and the fog server and verify that the host can load the pxe menu?
-
We are a Windows network with a Lightspeed filter, and my FOG machine is already a part of a filter bypass group, so its inability to access the internet is a little dumbfounding. In fact, when I check my web filter logs to see where the FOG machine has tried to go, it shows no attempts to access the internet at all (since yesterday). Weird?!?!
Anyway, thanks for the CNA information, I have it right now discovering my switches on the IP subnet where I have them all assigned!!
When you suggest moving the FOG server and a host machine to an isolated switch, do you mean just connecting the two machines to a single switch that is not connected to anything else?

That is very odd, however, I don’t have any experience with lightspeed.
In theory, yes, just connecting the two machines on the same switch without any other network access should work, as long as you can supply some kind of DHCP information.
If you would like we can set up the DNSMASQ service, I use this in my environment and it is actually the only way to resolve to my FOG server. It’s a quick easy set up, and it’s just as easy to remove. The DNSMASQ will act as a proxy dhcp server for machines looking to boot via TFTP, it will also help to point those machines to the correct boot file.

Jaymes, I have installed the FOG machine and a client machine (the HP Elitebook) on a spare Cisco 2960. I have also edited my ltsp.conf to match the one you showed me at [URL=‘http://fogproject.org/wiki/index.php/Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server#DNSMASQ_settings_for_iPXE’]http://fogproject.org/wiki/index.ph...with_no_DHCP_server#DNSMASQ_settings_for_iPXE[/URL]
I have also restarted the dnsmasq service.
Where is the tftpboot folder, so I can symlink according to your directions?

It is on the root of the drive.

cd /tftpboot [/code] -
On HP Elitebook (client):
no DHCP or ProxyDHCP offers were received.
I am using the exact ltsp.conf that you showed me (no changes).
FOG machine and Elitebook both plugged into Cisco 2960 ports 1 & 2
-
Since the FOG machine is not hooked up to my network anymore (because you had me move it to an isolated switch) I don’t know its IP address so I couldn’t modify to ltsp.conf to be any more specific.
-
I’m going to step in a little bit. You’re over thinking I think a little bit.
If you take the client system and place the network on the same switch as your FOG server does all work?
If it doesn’t work, then the problem is either DHCP isn’t handing out the right pointers to your FOG Server (Option 66/Option 67) or your switch is blocking the passing of this data to the FOG Server, or the service isn’t running on the FOG Server.If the first switch works, then step to the next switch and try again, if that doesn’t work then something in that second switch is blocking access out. If all works fine, step back to the next switch in the chain. And so forth.

You should set a static ip address for the machine. It shouldn’t matter what switch you move it to, you should always have the same ip address.
-
Okay, here’s where I am:
Both the client and the server are connected to a small 8 port hub (which is also connected to the network, so my server could have its IP address, 10.10.0.178).
I edited the ltsp.conf file from here [URL=‘http://fogproject.org/wiki/index.php/Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server#DNSMASQ_settings_for_iPXE’]http://fogproject.org/wiki/index.ph...with_no_DHCP_server#DNSMASQ_settings_for_iPXE[/URL]
the only active lines in the ltsp.conf are
[CODE]port=0
log-dhcp
tftp-root=/tftpboot
dhcp-boot=undionly.kpxe,10.10.0.178
dhcp-no-override
pxe-prompt=“Press F8 for boot menu”, 5
pxe-service=X86PC, “Boot from network”, undionly
dhcp-range=10.10.0.178,proxy[/CODE]When I PXE boot the client, TFTP picks up so fast that I can’t see without slow-mo what it’s saying. Then the screen reads “iPXE initializing devices…”
Then (thanks to slow-mo) it errors out with “/default.ipxe… Error 0x3d126001 ([url]http://ipxe.org/3d126001[/url])”
-
Well, since no one has had anything to say on this thread for many days, let me see if I can revive the discussion…
I have decided to scrap my current install and reinstall 13.10 and 1.1.2, with the intention of modifying my DHCP server settings to point PXE booting devices to the FOG server. The ProxyDHCP approach was my first choice because it wasn’t going to involve screwing with my DHCP server settings, thereby maintaining the integrity of my old system (Windows Deployment Services).
But, at this point, I am willing to “jump all in” to get a FOG server that works.
So, as I am getting ready to install FOG, what choices should I make during the install process, considering what I intend to do? Should I just choose the defaults, or does some special configuration need to happen?

Hi,
i think you are good with:
[LIST=1]
[][LIST]
[]Type 2 and press Enter for Ubuntu installation.
[]Type N and press Enter for Normal installation
[]Supply IP Address, it SHOULD be the static IP address you set up earlier, if it is not please revert to step 5 and try again.
[]Type Y and press Enter setup DHCP Server.
[]Enter the IP Address associated with your DHCP Server
[]Type Y and press Enter to set up DNS.
[]Enter the DNS Server address and press Enter.
[]Type N and press Enter to leave the default Network Card the same.
[]Type N to disable DHCP Service.
[][B]NOTE: It tells you that in order to use your PXE server you have to run a few commands on your DHCP server, this is not entirely true, but it definitely helps, this will point your clients to your server, or you can disconnect your server from the outside world while you image.[/B]
[]Type N to not install Additional Languages.
[]Type Y and press Enter.
[/LIST]
[]Next it will verify the settings, make sure everything has been entered correctly.
[LIST]
[][B]NOTE: I set up Fog with default passwords for MYSQL and users, you can supply information if you like, just make notes.[/B]
[]Type a password for the “root” user in MySQL and press enter.
[]Type the Password again and press enter.
[]Type the Password again and press enter.
[]Type Y to send your install information to the Project, and it will take some time to complete.
[/LIST]
[]Now we need to set up the web GUI for FOG. Open your browser and navigate to [URL=‘http://%28serveripaddress%29/fog/management’]http://(serveripaddress)/fog/management[/URL]. Or click the link in the Terminal window.
[]The web GUI will alert you to back up your database for MYSQL Server and install the upgrades, do so and follow the upgrade instructions.
[]Next log in, default user name is FOG and the password is password.

If you already have a DHCP server setup on your network you don’t want two. So if you chose to not install DHCP during FOG installation you will need to set some options in your current DHCP server to point PXE services to the FOG server.
[SIZE=5][B]Windows[/B][/SIZE][SIZE=4][B]0.33 and up[/B][/SIZE]
To set options 066 and 067 on Windows Server:
[LIST=1]
[]Open DHCP configuration [B]Start[/B] > [B]Administrative Tools[/B] > [B]DHCP[/B].
[]Then expand your server, expand the applicable scope (often only one is there)
[]right click on [B]Scope Options[/B]
[]click [B]Configure Options[/B]
[]tick [B]066[/B] and enter the IP Address of the FOG server
[]tick [B]067[/B] and enter [B]undionly.kpxe[/B].
[*]Make sure that 060 is unticked.

[]Edit your dhcpd.conf file (ie: vim /etc/dhcpd.conf)
[]In the global section or in a subnet declaration add [B]next-server X.X.X.X;[/B] and [B]filename “undionly.kpxe”[/B]; where X.X.X.X is the IP of your FOG server.
[]Restart your dhcpd server (ie: service dhcpd restart)

Scratch that.
I found these:
[url]http://www.fogproject.org/wiki/index.php/Integrating_FOG_into_an_Existing_Network[/url]
I have changed the DHCP settings (066 & 067) for a couple of scopes in my network (just to test), according to the above directions.
Now, to test!

Thanks, X23.
Your post must have been formulated as I was looking for the very answers you provided.

Well, still no joy:(
I get to a screen during the process that says:
iPXE 1.0.0+ (1639) – Open Source Network Boot Firmware – [url]http://ipxe.org[/url]
Features: NFS FTP HTTP HTTPS iSCSI DNS TFTP VLAN AoE bzImage ELF MBOOT PXE PXEXT

Configuring (net0 a0:1d:48:a9:e6:62)… ok
Could not start download: Operation not supported ([url]http://ipxe.org/3c092003[/url])The reference page at ipxe.org doesn’t make much sense to me, except that it suggests I am trying to use a protocol that is not supported by the ipxe build.
What have I done wrong?!
