I have no idea. Only thing I can think of is virtualBox not applying the port forward.
Everything else was identical.

I'm using:
cat hubfs/io1 &
cat hubfs/io2 &
cat >>hubfs/io0

with rlwrap to get something like a terminal.
Is there a way to send sigint? Is there some other way to get a terminal that can be wrapped in rlwrap and support sigint?
