<![CDATA[incorrect IPs in IPXE]]>Server
  • FOG Version: 1.4.4
  • OS: Ubuntu server LTS 16.04
Client
  • Service Version: hyperV/HP 800 G1
    (Same error on VM and workstation)
  • OS: Windows 7
Description

DHCP is served from a separate windows server. Option 066 (ip for fog server) and 067 are (undionly.kpxe) is correctly configured. Initially IP address and option 066 are correctly passed onto the PXE boot process.

Then when ipxe configures net0 with completely different information with IPs not even in the network scope. (see the below screenshot)

I manually configured ipxe ‘config’ command and it worked fine.

DHCP is configured with a second failover server (windows). I’ve double checked there are no other proxyDHCP or a rouge DHCP server connected to the network. Could someone shed some light into this issue. Is there any thing should I manually configure in FOG server?

Thanks In advance.

It was running from a VM on a regular PC. Network admins were able to locate the port relates to the MAC address of the rouge server.

Now PXE is booting to FOG smoothly

The OP is currently addressing the second dhcp server issue.

For this test your dhcp server, fog server, and pxe booting client should be on the same subnet so that we can see the entire pxe booting conversation. Capture the pcap and post to a google drive or dropbox. Either post the link here or send me an IM and I will take a look at it and tell you what is going on.

My DHCP settings are in 172.16.1.xxx range
