<pre wrap="" class="">Hi,
I am trying to get SIMH up and running on the ethernet interface of a
Raspberry Pi 3. I have followed the intructions in 0readme_ethernet.txt,
installing the libpcap-dev, bridge-utils and uml-utilities packages before
building SIMH itself. I just ran 'make vax' and let it go, and the build to
completion.

<pre wrap="" class="">Are you sure this applies to the machine running the “stretch” release?
The ‘ifconfig’ command on that system (well, on mine, anyway!) doesn’t display “inet addr” anywhere in its output, it just has “inet”.
So the various grep commands in your example don’t work.
Thanks

Oops, my bad. I did not realize that this Pi is the one remaining
that still runs jessie. I hate to convert because it doubles as my
OpenVPN server.<br class="">
