Summary of my last experiments:

Node A & node B inside VirtualBox (Linux) : that's the configuration i am running since the beginning of this discussion.

Node A & node B on a same MacMini (BSD). VirtualBox out of the loop.
=> same problem.

Node A on a MacPro, node B on the MacMini. VirtualBox out of the loop again.
=> same problem.

Node A inside VirtualBox Linux (MacPro), node B on the MacMini (BSD).
=> same problem.

We can rule out VirtualBox.

We can rule out a Linux/BSD/pcap problem.

We can rule out running multiple nodes on the same host (MAC addresses, etc).

Two versions of simh were used, 3.6 and 3.9, in Mac and Linux build.



[ Note: since simh 3.7, set console pchar=37777777777 if you want to use EDT/RMD/NTD at the console, took me an hour to figure. ]
