Re: dhcpd.conf for kickstart

[Chandler Wilkerson <chwilk@xxxxxxxx>]

The problem you're running into with the second file is that your dynamic range overlaps your static host entries. Dynamic is used as a fallback when your host doesn't match any of the static rules. If you shrink the dynamic range, your statically defined hosts should start getting static IPs and PXE booting.

When I use the first dhcpd.conf my kickstart works fine

When I use the 2nd one I get

 

PXE-E53: No boot filename received

I am trying to get the dhcp server to assign a specific IP address based on the mac address and download the exact ks.cfg for that server.

What am I doing wrong?
