Folks,
I'm trying to get BSD 4.2 running on a VAX 11/780/simh setup.. I'm
having difficulty with networking.
Are you trying to tunnel your traffic over a wireless interface on the host
machine running simh? 802.11 is not 802.3, but it's a common thing
people try to do on laptops.

No; this is on a server, where I spun up its own OpenBSD VM to run
SIMH underneath it. It's all wired ethernet. I think the issue is with
4.2BSD and not with SIMH or anything else. I used the distribution
In playing around in the 4.2 userland that is created I found...
1) MAKEDEV doesn't have info for "en0"
2) running "strings /vmunix | grep en%" doesn't find anything, like
the kernel doesn't have ethernet device (xu) support built in
3) There is no uname in 4.2 BSD, so all I know is that the /vmunix
supplied is "4.2 BSD UNIX #9: Wed Nov 2 16:00:29 PST 1983"
4) Looking at /sys/conf/GENERIC there is no entry for en0 (and on
further examination, the compiled GENERIC is the same size/checksum as
/vmunix)
So, it looks like the default 4.2 BSD kernel doesn't have ethernet
drivers. Off to compile a new kernel. I'm worried that even with a new
kernel, I don't have the right MAKEDEV script and don't have the right
major/minor numbers to even manually mknod the en0 device on my
system. But I'll cross that bridge when I get there.
