<div class="moz-cite-prefix">My SIMH VAX is behind a reliable
IDS/IPS, so I wrote a stupid program to do a "RUN
SYS$SYSTEM:OPCCRASH" when a TCP connection is made to a specific
port. It's at QCOCAL::REMOTE-SHUTDOWN-LISTENER.ZIP if you are on
HECnet. An obvious minimum improvement would be to support some
sort of port-knocking.<br>

I have also been in search of a solution for this. I'm OK with using
screen if necessary.

It's the shutting down part that's the problem for me. The operating
systems I'm interested need to have a user login and type a command to
shut down cleanly. This is hard to do reliably.
Possible workarounds for this include abusing the hardware power fail
interrupt to initiate shutdown, or listening for a signal from the
network.
