Hmm. I also got that error when I set the correct hardware address on the tap0 interface before launching pydecnet.

Ah, using the pcap option to talk to the tap virtual device? I'll try that.



And regarding the http server, I pulled out the routing line when pydecnet complained about both it and http existing in the same file, but I didn't catch that I also had to have the routing line defined in a separate file. I'll try that, too.

Dumb question time, because I struggle with VMS: Is there a DECnet equivalent to "ping" that I can use to verify that my emulations can talk to pydecnet? I gather that's what the mirror server is for, but I don't know how to invoke it on the VMS side.
