The init scripts attempt to start it, but it isn't running.
start-stop-daemon ends up exiting with an error about /proc
(about not being mounted).

While we're here, why is that?

Outdated version of start-stop-daemon or is something supposed
to be attacthed to /proc ?

It's something I wrote myself. It just calls connect() on each port
in a given port range.

Although I'm assuming inetd isn't starting, the portscanner seems to
trigger on all of the ports that have been specified in /etc/inetd.conf

I'll follow up
