I suppose it might be worth opening the query up to the list anyway - any good reason why I shouldn't be able to connect the Digital UNIX implementation of DECnet/OSI to HECnet? The Software Product Description attached to the previous email has more details of the implementation. Regards, Mark. Should work just fine. People have been running DECnet Phase V on VMS systems on HECnet. This is no different. I don't know if DECnet Phase V also use some other ethernet protocol number for V <-> V communication, but when talking with Phase IV nodes, it's the same standard protocol number as it has been all along.
