Never mind, it looks like this was a permission error, I wasn't using sudo. I suppose it would be helpful to log the reason for the open error.

I have been using SIMH successfully for quite some time on a Raspberry Pi, with my network adapters connected to eth0. However I recently bought a new Raspberry Pi 3, now I get this: MicroVAX 3900 simulator V4.0-0 Beta git commit id: f081ddf9 NVR: buffering file in memory libpcap version 1.6.2 Eth: Must specify actual tap device name (i.e. tap:tap0) ./microvax3900.ini-29> attach xq eth0 File open error I don't have any TAP interfaces defined on either Pi, to be honest I don't know a whole lot about them and I am not sure if I need to define one or why. Any ideas why it won't attach to eth0 anymore? Regards Rob
