I just "dd"ed mine to an ISO file. No problems there. If you have some ftp site that I can upload it to, I can send you my .iso later tonight. Thanks, that would be quite helpful. Can you sftp? If so, I'll send you a login you can use. If my math is right, aa:00:04:00:11:08 works out to 2.17 (and that's the right address). It does look like Charon-AXP changed the hardware address of the interface correctly, then. # The trailing zone network interface auto eth1 iface eth1 inet manual pre-up /sbin/ifconfig eth1 hw ether aa:00:04:00:d5:08 I'll give that a try next. Question - is "auto eth1" the right thing to do? That makes the interface start up when the boot does an "ifup -a", right? I didn't do that (I figured Charon would start it when it got around to it). I'm far from an expert on Linux network interfaces. It doesn't seem to harm anything, and I do want the interface to be up for the emulated system. Since Charon-AXP is expecting to have dedicated access to the interface, it may do a lot more configuration and management of the interface than I expect. I've been using this setup with SIMH VAX and PDP-11, and something similar for Panda (TOPS-20), so it's just a matter of course for me when I'm setting up an emulated system (that uses DECnet, anyway). --Marc
