Brian: Going out on a limb here, my intuition is telling me that if you remove the "attach xq0 ethX" line in your vax.ini file, the Simh will start normally.
Are you running Simh as root? On my system, at least, I have to run it as root. According to Wherry this is due to the Simh ethernet code needing to put the NIC into promiscuous mode. When I try to run Simh as a normal user, I don't get a segfault. I get: ./vax.ini> attach xq0 eth1 File open error You're system may be configured differently than mine, however, resulting in a segfault at the same place. By the way, do you have a dedicated NIC for the Simh or are you doing the TUN/TAP thing?
