Yes, I did create a new kernel and copy it to the correct place and
chmod 644 the new unix file.
On my Debian system I can install ftpd and telnetd (they are still in
the Debian package list) which are the unsecure ones, but I don't know
how to configure them or start them. As in, # systemctl restart ftpd
It turns out to not be a hot topic: "How do I make my Liinux system less
secure?", but for us that noodle around with old computers with
obsolete operating systems it is exactly what we need. In the past I
remember using Filezilla to go from a Windows7 machine into a Vax
without any problem.
