Bob,
I've seen a couple of these lately. I'm starting to feel that it is a
kernel bug, or that the net-tools are somehow trailing behind the
kernel development. I'll have a chance to follow this up in some detail
this weekend when I bring my own test configuration up to 2.1.42 and
the ax25-utils to to it as well.

Could I get you to try:

# ifconfig ax0 arp
# arp -H ax25 -i ax0 -s 44.10.0.169 WD6DOD-3

ie, manually enable arp on the interface,

and if that doesn't work, then try:

# strace arp -H ax25 -i ax0 -s 44.10.0.169 WD6DOD-3

and to post arp.strace to the list please ? This will give us
some idea of what is happening internally.

Syntactically it looks correct enough.

Terry
