I can tell from the packet trace that iPXE's DHCP client believes that it hasn't received any DHCPOFFERs, since bits 0 and 1 of the "secs" field are always zero. (Inspired by this, I've also just added code that will enable me to tell from a packet trace whether or not iPXE has received any packets at all.) There are some helpful hints (some of which are new) on the relevant error page: http://ipxe.org/4c106035 What does "ifstat" show after the failed DHCP attempt? What happens if you try a static IP address? Michael _______________________________________________ ipxe-devel mailing list [email protected] https://lists.ipxe.org/mailman/listinfo/ipxe-devel
