We've moved to GRUB 2 as a development platform. Unfortunately, GRUB 2 doesn't have network support yet, although there's ongoing work to implement it. If you want to help on that, please contact <grub-devel@gnu.org>.

In the meantime, this bug doesn't apply. I'm closing it.

It is the bug on the implement of the UDP/IP stack in diskless patch. I'll fix it in the next version of diskless patch (grub-0.95-diskless-patch-2).

When using Grub to Net Boot Cluster Knoppix 3.4 via a RTL8169, grub hangs if it receives ARP or unsolicited UDP traffic before starting any TFTP download (kernel or cfg file).
I compiled the latest CVS Grub (June 5th 2004) patched with the diskless pack 3.
I can systematically reproduce this after resetting and net grub rebooting one of the machine previously active on the network used by a Knoppix cluster of at least 2 computers. AS info, the machines of the cluster knoppix exchange UDP info every seconds and continue trying to do so after the reset of the computer which prevents grub to net reboot via tftp even though the DHCP transaction is ok.
Grub works fine if no traffic hits grub before the tftp download (tcpdump), by disconnecting the 2nd cluster knoppix computer before grub starts on the first computer.
I don't know if this is tight to the RTL8169 only or if this is a general problem with all network card adapters yet. More info later...
Hope this will help the Grub development and debug, Gilles.
