Re: Mopd which works with ELF and a.out in Linux and can netboot ULTRIX
I can't really figure out what you are doing, or where you get into trouble.
I can report that I successfully am booting NetBSD/vax over the network
from time to time. In my case a MicroVAX-4000/90, and it is served by a
simh VAX-8650 running NetBSD as well. I use this whenever I mess up my
boot block or /boot on the 4000. Especially /boot often gets into
trouble, as recently built /boot always seem to fail. But I have an
older version around, that I fall back to. But in order to fall back, I
need to netboot, and then mount the disk and replace /boot.
I think I am using a fairly recent installation system for the

Thanks to Boris's help below, I now have it booting up to a point. Wireshark shows 7594 packets to and from the microvax.
I had previously tried all the config files setting suggestions to get NFS to support V2, but found this little gem that solved the problem:
rpc.nfsd 0 && sleep 1 # Stop all previous threads
rpc.nfsd --nfs-version 2,3 8 # Restart 8 threads with versions 2 and 3
I haven't tried these particular things, but recently I was doing some work with the Linux NFS server and found that it supports NFS V2 out of the box. In fact, that is the default support; V3 and V4 are both optional, interestingly enough. However, V2 is not enabled by default. A setting in the [nsfd] section of /etc/nfs.conf takes care of that:
This is also where you can enable NFS over UDP (which also defaults to off).
I verified the V2 support by asking my Mac to mount a Linux NFS volume using V2. Yes, Mac OS supports V2 in its client, to my great surprise. Wireshark confirms that it really is using V2.
All this is with a shiny new Linux kernel, 5.8.16, the one that comes with Fedora Core 32.
