(Error code 4c1060)

Possible sources

This error originated from one of the following locations within the iPXE source code:

General advice

  • Try using the latest version of iPXE. Your problem may have already been fixed.
  • You can contact the iPXE developers and other iPXE users.
  • Refresh this page after 24 hours. This page is actively monitored, and further information may be added soon.

Additional notes

(Please edit this page to include any of your own useful hints and tips for fixing this error.)

This error indicates that DHCP has timed out without receiving a response from a DHCP server.

Things to try:

* Watch traffic on the DHCP server in real time

* If your VM bridge network doesn't have multiple routes, then you may not need STP at all, in which case set

bridge_stp off

in /etc/network/interfaces (Debian).

Here be dragons

Advanced troubleshooting

You can use a packet trace to determine which types of DHCPOFFER have been received by looking at the “seconds elapsed” field in any DHCP packets transmitted by iPXE:

Bit 0 Indicates that a DHCPOFFER containing PXE options has been received
Bit 1 Indicates that a DHCPOFFER containing an IP address has been received

For example, suppose that the packet trace shows a DHCPDISCOVER containing:

DHCP packet showing "Seconds elapsed: 14"

The “seconds elapsed” value in this example is 14, which is 0b1110 in binary. Bit 1 is set, indicating that a DHCPOFFER containing an IP address has been received. Bit 0 is not set, indicating that no DHCPOFFER containing PXE options has been received.
