| I've seen this error before with multiple different O/S netboot files, including even Solaris. The problem is almost always an interrupted transfer (from the perspective of the OBP TFTP client, which is very basic). This can sometimes be due to an incompatibility between the OBP and the network infrastructure or TFTP server - especially around IP-fragmented UDP packets, or shorter-than-expected (but completely valid and complete) packets. Getting an older TFTP server software or upgrading the OBP version can help avoid this issue. As always, YMMV. -- Mike -------- Original message -------- From: Matt Wallis <mattw%madmonks.org@localhost> Date: 28/04/2025 05:59 (GMT+00:00) To: port-sparc%netbsd.org@localhost Subject: Failing to netboot What am I missing here? I’m trying to netboot my IPX, I have rarpd and tftp running on an rpi, and I can see rarp and tftp responses to the IPX.

The DHCP server is currently running on a Ubiquiti Dream machine, the interface can make seeing what options are configured a bit difficult, but I can enter any custom options I want. Even setting the DHCP protocol number on it. If anyone has any thoughts on what I might be missing, appreciate all the help. Matt. |
