I have UCX on both of them; I use LOKI by far the most. If you were willing to switch to Multinet (which has a free hobbyist license _and_ is a lot better than UCX) you'd be all set to connect. Quick question--LOKI already has DECnet-Plus installed, that will work for HECnet, right? As I understand it, DECnet-Plus is backwards compatible with Phase IV? It's supposed to be, but I don't know anyone on HECnet who is actually using it. Many/most HECnet nodes are rather old and can barely manage Phase-IV :-) Bob
