YES, It’s works !!! Such a simple misteake, thx for patience and everything

I was looking for this file, it wasn’t there, I reinstalled FOG and magic happend ;]

Now I will be testing multicast !!! Keep your fingers crossed, i will let you know

@george1421

Thank you for your response. I don’t know why but I thought all the time that FOG should be installed on the server / router behind NAT. It didn’t occur to me that it could be a normal host on the network. I don’t need Fog working as a router and image server. Now I see that it makes no sense. So I’ll try to install it on a separate host computer and see what happens.

My switch is TP-LINK TL-SF1024. So it’s not an advanced device. But if I can run FOG on it, I’ll talk to my boss about something better.

Thanks to everyone for the answers, I will let you know if it works.

I had a problem when capturing an image when the computer was in legacy mode, when it was in UEFI mode everything worked. Then I reinstalled FOG on PROXMOX and I didn’t check Legacy mode anymore, but now I just tested imaging in legacy mode and everything works. That’s why I thought it was somehow dependent on whether fog was installed in UEFI/Legacy mode. Topic to close then.

Hi, I’m moving FOG to Proxmox. I currently have FOG installed on a physical computer on Ubuntu Server in Legacy mode, and I’m restoring systems in legacy mode. On the second computer I put Proxmox and there I created a VM with Ubuntu using the default SeaBIOS. Both FOG servers use dnsmasq with the same config (only different FOG server IP addresses). However, during registration and later restoring images from FOG on Proxmox, FOG uses booting after UEFI, not BIOS. Can someone explain to me why this is happening? Is it related to SeaBIOS? Or is it because Proxmox is based on UEFI?
I would like to be able to restore systems on Proxmox in both Legacy and UEFI mode, how to set legacy mode on VM in Proxmox?

Hello everyone, I have Fog installed on Ubuntu 24.04.1 on a virtual machine on proxmox. I get this error on the client:

“https://192.168.25.11/fog/service/ipxe/boot.php… Error 0x420c6001 (https://ipxe.org/420c6001)
Could not boot: Error 0x420c6001 (https://ipxe.org/420c6001)”

what could this mean?

edit:
It looks like I messed something up during the installation. I suspect it’s the DNS. I didn’t notice, but it detected the DNS as localhost by default. When I changed it, FOG started on the client.

@george1421

thank you george, the current switch is unmanaged, it’s a simple switch. There is not much in the specification of the switch, so I bet that switch is the problem.
All PCs are the same and support WOL and on the old switch they all turn on, but I will check it, maybe one of the students has changed something in the BIOS

Multicast is working, but …

First I used my old switch TP-LINK TL-SF1024 and it’s faild. Two PCs restored at a rate of 150MB/min,

Second time I used LinkSys LGS308, 8 x 1Gb ports. I start to restore 2 other PC and only one turn on from network, second i turn on by my self but the multicast session starting, and both PC restore at rate of 10GB/mmin. Then I connect third PC to the switch and strat multisession once again one PC turn on but second and third i have to turn on. Again multicast worked very well (10GB/min at each PC)

Do you have an idea why only one PC wake on LAN?
Whether the old switch may not support multicast?

There is no / tftpboot directory.

I install everything again, I have no idea what happened to this catalog. I could have sworn that this catalog was yesterday.

@george1421
your suggestion did not work. I looked for TFTP troubleshoting like @Sebastian-Roth says and used the command:

tftp -v x.x.x.x -m binary -c get undionly.kpxe

and i have got nothing.
I searched the system a bit and found something like this:
this is my tftp-hpa configuration file

# /etc/default/tftpd-hpa

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/var/lib/tftpboot"
TFTP_ADDRESS=":69"
TFTP_OPTIONS="--secure"

there are no files in this directory, so where is the undionly.kpxe?

@george1421

This is from Ubuntu server 18.1 and dnsmasq 2.9 verssion:

Hi again.
Now I have one network interface - the FOG server plugged in the switch. Switch is plugged into hardware dhcp so I used dnsmasq from here and then soluion from here

in both cases I get something like this:
