What isn't made clear here is that Decnet aliases the hardware ethernet
address of your interface so if you 'arp -a' from your tcpip system
you should see what looks like a bogus hardware address for the system
running Ultrix-Decnet.
-more like 'aa:0:4:0:4:dc' instead of '8:0:2b:7:64:de'. The 'aa' is a
tipoff as all DEC systems start with 8:0:2b - if you see the real hardware
address do an 'arp -d targetname' to get
the decnet aliased address in the arp table. (by deleting the earlier one)

In your /etc/rc.local start up decnet and sleep or do something else
for a few seconds before starting 'ifconfig' so ifconfig picks up the
aliased address. (Why is this, Fred? - not complaining a bit - just
curious - the Ultrix Decnet is so nice to have)
