Re: Mopd which works with ELF and a.out in Linux and can netboot ULTRIX

I thought that you may have provided the very last little nugget of
configuration that would get me going, but alas, it still gets a kernel
panic after many thousands of packets have gone across the wire:

Any help appreciated!

Merry Christmas, Happy Holidays. Have a cool yule, etc

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:
