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.

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

@george1421

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?

@george1421

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:

@Sebastian-Roth

So it’s easiest to install FOG on a separate server with one card and plug it into the switch. Do I understand correctly?
