Can not deploy using multicast - read image_hdr block_size error

@rurap If you simply rerun the fog installer it will recreate these files in the proper location.
Also you can search the entire disk for these files with
sudo find / -name undionly.kpxe -
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 ;]

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? -
@rurap Some small/older switches don’t have the internal bandwidth capable to send out multicast streams to all switches. On your tp-link switch, if it has a management interface see if it has an option for igmp snooping or anything regarding to multicasting and sparse mode or dense mode. You may just want to shop on ebay for older enterprise switches from HP or Cisco.
As for wake on LAN, that is a feature that needs to be enabled in the computer’s firmware to support WOL. I’m sure the FOG server is sending out the WOL packet, the computer has to be configured to accept it.

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
