[HECnet] SIMH VAX config changes

Hello All, I've just cycled one of my old systems which in addition to regular duties also ran my VMS on SIMH system which participated with some of my real VAXen and Alpha systems. I've built v3.11 of simh and I'm having difficulty with the newer Pcap device and wondered if someone else knows the silly obvious thing I'm doing wrong. Setup: Ubuntu Server 18.xx LTS. 2x NIC's on the system. One's "eth0" (primary) and a secondary USB one which is obviously called "enx00e04c360059". Ideally, I'd like to use one NIC for a promiscuous mode Ethernet, the other for regular scheduled programming. I've built SIMH in the usual fashion and dumped the binary's symbol tab via nm and the usual suspects from libpcap seem to be statically linked and present. I can: # id uid=0(root) gid=0(root) groups=0(root) # /tmp/simh/BIN/vax VAX simulator V3.11-0 sim> attach xq eth0 Eth: Pcap capable device not found. You may need to run as root File open error sim> attach xq enx00e04c360059 File open error sim> show xq eth ETH devices: eth0 udp:sourceport:remotehost:remoteport (Integrated UDP bridge support) sim> This seemed to work quite happily in the old O/S combo and with an older simh + pcap. Can someone please point me in the correct direction? Thanks in advance.
