[HECnet] Alpha emulation?

Guys - Sorry to bother you with a question, but I was wondering if anyone who had tried Charon-AXP-nce was successful at getting DECnet running on OVMS 8.3 under the Charon emulation? I installed Charon-AXP-nce (no sweat there, and thanks for the pointer to it). It boots and runs OVMS8.3 just fine. First I used their sample pre-installed system disk image, and then I mounted the OpenVMS Hobbyist Alpha CD on the simulated CDROM and re-installed my own OpenVMS. Registered hobbyist licenses, etc. No problems. Then I installed a second Ethernet card on my Linux host system. Had a little bit of trouble getting udev, Network Manager and DECnet/Linux to all cooperate on which interfaces to name and use, but I eventually got that all straightened out. Now I have an eth1 device which nobody on the Linux host is messing with. I modified the start_es40_nce to use eth1 for EWA0. It appears to work - I can start DECnet on the emulated OVMS system, and I get circuit up and adjacency up events from DECnet. Looks great, but... Whenever I try any outgoing connection from the emulated Charon-AXP system, I always get "network communication error" and "network partner aborted logical link". No outgoing connection seems to work; not SET HOST, not FAL, not NCP, nothing. BUT the really weird thing is that it works in the other direction. I can go to CODA (a real Alpha system) and SET HOST to the Charon emulated system. That works just fine, as does NCP, FAL, etc as _inbound_ connections. Has anybody seen this behavior with DECnet before, either under emulation or on real hardware? What could cause this? Thanks, Bob
