@george1421 you are the man!

Finally getting to see the PXE menu. I haven’t tried to deploy or capture an image yet but it seems like it should work no problem. One thing though… when trying to live boot an ISO (DLC, True Image, etc.) I get the error =:

El Torito BVD sanity check failed
El Torito boot catalog sanity check failed

MEMDISK: bootstrap too large to load.

Any ideas?

P.S sorry for the late reply. UK time!

@george1421 Thanks for getting back. I’ll explain the situation. I work for a computer repair shop and our IT support is outsourced so I don’t have any access to the router. All the machines that we’ll be imaging are on the same subnet (192.168.0.0/24) and received DHCP info from the router/gateway at 192.168.0.1. If things get really tough I suppose I could contact support and ask them to change some settings on the DHCP server but I’d rather find a work around.

I’m totally new to dnsmasq and isc-dhcp so to be honest I’m not 100% sure what the best route to take is. It looks from what you’ve explained that dnsmasq is probably the best path for me.

dnsmasq is on version 2.78 and I got the same response as yourself.

I’ve now replaced the ltsp.conf file to what you recommended. Whats next?

Hi guys,

I’m having trouble getting tftp to work using dnsmasq. I followed the wiki and set up dnsmasq, and can get the client to retrieve an IP address and begin the tftp process from the server @ 192.168.0.66 but it fails to retrieve any files and fails.

And the output for ltsp.conf for dnsmasq:

Once again, appreciate any help with this guys.

@wayne-workman @george1421 It worked! in hindsight I should have just changed the management user, my bad.

Thanks again!

dylz

Thanks for the quick reply. I spent so long trying to modify everything so the Fog user was being used for TFTP but then I decided to edit everything for the user I set on startup. Running now so hopefully it works.

Appreciate the time you guys take to comment so quickly!

Hi guys. Back again with some new issues. So I had to do a clean install of Ubuntu and Fog and I’ve managed to get everything working up until it’s time to update the database with the image file after a capture task is complete.

So I have tried “passwd fog” and “passwd -d fog” and retried but the issue persists. The weird thing is that there wasn’t a home folder created for the Fog user initially so I created one and tried again to no prevail.

I’ve had a look past previous forums too and tried some solutions but nothing seems to work. I’m on the latest updated version. So there’s clearly an issue with ftp/tftp here trying to access the server through the Fog user. I changed the default Fog user and password instantly after setup but I also created a new user named Fog when trying to troubleshoot this but there’s no success.

Really appreciate the help guys. Thanks in advance!

I have finally figured it out. The ISO’s won’t boot in UEFI mode and must be set to legacy (BIOS)
For now everything is working. Thanks for the help guys.

dylz

@sebastian-roth I see. I suppose I’ll need to try dig in to this a lot more and figure out how to get this working. DLC boot is a diagnostics iso that I got from a colleague in work. It is similar to hirens with that it boots to a menu with mini windows environments, clonezilla, partitioning tools etc…

I also have a custom Win10PE environment that I am going to try out and see if the results are any different. Should the ISO typically boot up as soon as it is done downloading the image to RAM?

dylz

@george1421 Thanks for the advice that helped big time. But there’s still an issue. The ISO seems to download but nothing boots. I take it I need to replace “goto MENU” with a command that makes it boot the live cd now?

dylz

@sebastian-roth Thanks I’ll open a new thread. I tried removing the $ sign but it just takes me back to the menu.

The new thread has been opened up here

Failing to get DLCboot ISO to boot through this method.

I have tried with the iso in 2 locations: /ISO/DLCD/DLC.iso and /var/www/service/ipxe/DLCD/DLC.iso

I keep getting similar errors. First I tried with these paramaters

:DLCD
initrd http://$192.168.25.66/var/www/fog/service/ipxe/DLCD/DLC.iso
chain memdisk iso raw ||
goto MENU

And I got this error:

Then I tried with

:DLCD
initrd http://$192.168.25.66/var/www/fog/service/ipxe/DLCD/DLC.iso
boot || echo failed to boot
prompt
goto MENU```

and got this error

I then tried removing the $ from the beginning of the IP address but it just takes me back to the FOG menu automatically

Any help or suggestions on why this is timing out or what I am doing wrong would be greatly appreciated. Tearing my hair out with this one.

Thanks
