Hi, folks,
We've been using pxeboot to pull up a menu, to build or rebuild machines for years. We have this new server, and it fails. Times out. What's happening is that it tries in this order .../pxelinux.cfg/b8945908-d6a6-41a9-611d-74a6ab80b83d .../pxelinux.cfg/01-88-99-aa-bb-cc-dd .../pxelinux.cfg/C0A8025B .../pxelinux.cfg/C0A8025 .../pxelinux.cfg/C0A802 .../pxelinux.cfg/C0A80 .../pxelinux.cfg/C0A8 .../pxelinux.cfg/C0A .../pxelinux.cfg/C0 .../pxelinux.cfg/C .../pxelinux.cfg/default
The first are MAC addresses, etc. I want it to pull default. It takes *minutes* to time out each option, so after a dozen or 15 min, when it gets to defaul, tftp has timed it out.
I've never seen that sort of delay before, but it's tough to strace an PXE environment. :-)
Now, our dhcpd config has this for pxeboot: group { allow booting; allow bootp; filename "gpxelinux.0"; option-209 = "pxelinux.cfg/default"; option subnet-mask 255.255.254.0; option routers <our router>; default-lease-time 172800; # 2 days. max-lease-time 432000; # 5 days.
Do you have a next-server option that points to your tftp server? I've always hardcoded an IPv4 address into that setting:
group { # normal stuff next-server 10.11.12.13; filename "gpxelinux.0"; }
Also, in case you're ever interested, I've written a script that generates suitable IPv4-based filenames for pre-default usage:
