I need some help with a PXE/TFTP problem. My cobbler server has two
NICs; the "primary" is connected to the 'net, and the secondary is
dedicated to a deployment LAN.
DHCP and PXE/TFTP work very well when both NICs are connected. However,
when I disconnect the primary (internet) NIC, TFTP does some ... weird
things
When I PXE boot a system that isn't defined in cobbler (because I want
to just use the boot menu), the search for the boot file takes 20
seconds between each failure:
Trying to load: pxelinux.cfg/44454c4c-4a00-1057-8035-cac04f314431
[~20 second pause...]
Trying to load: pxelinux.cfg/01-00-19-b9-cd-8c-43
[~20 second pause...]
Trying to load: pxelinux.cfg/C0A80A69
[~20 second pause...]
Trying to load: pxelinux.cfg/C0A80A6
[etc...]
(full log at

This problem does not occur when the primary NIC is connected. When its
connected, it still searches, but each one immediately fails, until it
gets to pxelinux.cfg/default -- then it gives me the menu as expected.
The whole process takes under 1 second.
Also, if I start a PXE boot with the primary disconnected, then connect
the primary NIC while the boot is stalled, it returns to its normal
speedy boot.
Not sure if relevant -- In "settings" my "manage_dns" is 0.
Any ideas what is causing the delay?
