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

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

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?
This is from Ubuntu server 18.1 and dnsmasq 2.9 verssion:
# Don't function as a DNS server:

# Log lots of extra information about DHCP transactions.
log-dhcp
# Set the root directory for files available via FTP.

# Disable re-use of the DHCP servername and filename fields as extra
# option space. That's to avoid confusing some old or broken DHCP clients.

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:
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.
So it’s easiest to install FOG on a separate server with one card and plug it into the switch. Do I understand correctly?
@Sebastian-Roth said in Can not deploy using multicast - read image_hdr block_size error:
Are you aware of the NAT configuration on your system? Why do you seem to have two network interfaces on this machine?
It seems to me that some misunderstanding has crept in. Maybe because of the lack of my language skills.
my network looks like this:
I have an ubuntu 16.04 server set up on a regular pc (dell optiplex 7010) with 2 network cards.
To one card I connected the network from the outside and the other card I connected to the switch and then to other computers in the class
I installed and configured the dhcp server, shared the internet from the first card to the second, so that the internet works in the classroom. Then I installed and configured FOG
Everything works, imaging, restoring and internet. Only multicasting does not work.
I don’t have much experience in networks, did I do something wrong up to this point?
