That's probably not the bug.  We use a perfectly normal sun kernel
with an IEN116 nameserver with the UB products.  The problem that
we have is that the UDP checksum code in the UB box is defective.
If you do not have udp checksumming turned on (you leave the checksum
field zero), the box doesn't realize that you are not computing checksums
and ignores you.  The quick solution is to turn on checksums on the
machine that is providing name service (on BSD UNIX poke _udpcksum to
1).
