Here's what I did to get DECnet running on my TOPS-20 system (Panda distribution). 1) Preconfigure the Ethernet interface with the right MAC address with ifconfig xxx ether aa:00:04:00:xx:xx Happen to know what MAC i'd want for 33.254? I'm bad with figuring hexadecimal stuff and i've not quite figured out the order for DECnet mac addresses yet. If my math is correct, it'd be aa:00:04:00:fe:84. It's 33*1024 + 254 = 84fe, and then you swap the bytes. Does that sound right to others? --Marc
